    Measurement and stratification of nonsuicidal self-injury in adolescents2024Ingår i: BMC Psychiatry, E-ISSN 1471-244X, Vol. 24, nr 1, artikel-id 107Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BackgroundNonsuicidal self-injury (NSSI) is highly prevalent in adolescents. In survey and interview studies assessing NSSI, methods of assessment have been shown to influence prevalence estimates. However, knowledge of which groups of adolescents that are identified with different measurement methods is lacking, and the characteristics of identified groups are yet to be investigated. Further, only a handful of studies have been carried out using exploratory methods to identify subgroups among adolescents with NSSI.MethodsThe performance of two prevalence measures (single-item vs. behavioral checklist) in the same cross-sectional community sample (n = 266, age M = 14.21, 58.3% female) of adolescents was compared regarding prevalence estimates and also characterization of the identified groups with lifetime NSSI prevalence. A cluster analysis was carried out in the same sample. Identified clusters were compared to the two groups defined using the prevalence measures.ResultsA total of 118 (44.4%) participants acknowledged having engaged in NSSI at least once. Of these, a group of 55 (20.7%) adolescents confirmed NSSI on a single item and 63 (23.7%) adolescents confirmed NSSI only on a behavioral checklist, while denying NSSI on the single item. Groups differed significantly, with the single-item group being more severely affected and having higher mean scores on difficulties in emotion regulation, self-criticism, number of methods, higher frequency of NSSI, higher rates of suicidal ideation and suicidal behavior and lower mean score on health-related quality of life. All cases with higher severity were not identified by the single-item question. Cluster analysis identified three clusters, two of which fit well with the groups identified by single-item and behavioral checklist measures.ConclusionsWhen investigating NSSI prevalence in adolescents, findings are influenced by the researchers' choice of measures. The present study provides some directions toward what kind of influence to expect given the type of measure used, both with regards to the size of the identified group and its composition. Implications for future research as well as clinical and preventive work are discussed.

    A many-analysts approach to the relation between religiosity and well-being2023Ingår i: Religion, Brain & Behavior, ISSN 2153-599X, E-ISSN 2153-5981, Vol. 13, nr 3, s. 237-283Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N = 10, 535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-being, and (2) whether the relation between religiosity and self-reported well-being depends on perceived cultural norms of religion (i.e., whether it is considered normal and desirable to be religious in a given country). In a two-stage procedure, the teams first created an analysis plan and then executed their planned analysis on the data. For the first research question, all but 3 teams reported positive effect sizes with credible/confidence intervals excluding zero (median reported beta = 0.120). For the second research question, this was the case for 65% of the teams (median reported beta = 0.039). While most teams applied (multilevel) linear regression models, there was considerable variability in the choice of items used to construct the independent variables, the dependent variable, and the included covariates.

    Acoustic Features Distinguishing Emotions in Swedish Speech.2023Ingår i: Journal of Voice, ISSN 0892-1997, E-ISSN 1873-4588, artikel-id S0892-1997(23)00103-0Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Few studies have examined which acoustic features of speech can be used to distinguish between different emotions, and how combinations of acoustic parameters contribute to identification of emotions. The aim of the present study was to investigate which acoustic parameters in Swedish speech are most important for differentiation between, and identification of, the emotions anger, fear, happiness, sadness, and surprise in Swedish sentences. One-way ANOVAs were used to compare acoustic parameters between the emotions and both simple and multiple logistic regression models were used to examine the contribution of different acoustic parameters to differentiation between emotions. Results showed differences between emotions for several acoustic parameters in Swedish speech: surprise was the most distinct emotion, with significant differences compared to the other emotions across a range of acoustic parameters, while anger and happiness did not differ from each other on any parameter. The logistic regression models showed that fear was the best-predicted emotion while happiness was most difficult to predict. Frequency- and spectral-balance-related parameters were best at predicting fear. Amplitude- and temporal-related parameters were most important for surprise, while a combination of frequency-, amplitude- and spectral balance-related parameters are important for sadness. Assuming that there are similarities between acoustic models and how listeners infer emotions in speech, results suggest that individuals with hearing loss, who lack abilities of frequency detection, may compared to normal hearing individuals have difficulties in identifying fear in Swedish speech. Since happiness and fear relied primarily on amplitude- and spectral-balance-related parameters, detection of them are probably facilitated more by hearing aid use.

    Doubtful Clinical Value of Subtyping Anti-U1-RNP Antibodies Regarding the RNP-70 kDa Antigen in Sera of Patients with Systemic Lupus Erythematosus2023Ingår i: International Journal of Molecular Sciences, ISSN 1661-6596, E-ISSN 1422-0067, Vol. 24, nr 12, artikel-id 10398Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The detection of antinuclear antibodies is central to the diagnosis and prognosis of systemic lupus erythematosus (SLE), primary Sjogrens syndrome (pSS) and mixed connective tissue disease (MCTD). Anti-U1-RNP and anti-RNP70 antibodies were assayed in the sera of patients with SLE (n = 114), pSS (n = 54) and MCTD (n = 12). In the SLE group, 34/114 (30%) were anti-U1-RNP positive, and 21/114 (18%) were both anti-RNP70 positive and anti-U1-RNP positive. In the MCTD group, 10/12 (83%) were anti-U1-RNP positive, and 9/12 (75%) were anti-RNP70 positive. Only one individual with pSS was antibody positive (for both anti-U1-RNP and anti-RNP70). All anti-RNP70-positive samples were also anti-U1-RNP positive. Anti-U1-RNP-positive subjects with SLE were younger (p < 0.0001); showed lower concentrations of complement protein 3 (p = 0.03); had lower eosinophil (p = 0.0005), lymphocyte (p = 0.006) and monocyte (p = 0.03) counts; and had accrued less organ damage (p = 0.006) than the anti-U1-RNP-negative SLE patients. However, we observed no significant clinical or laboratory parameter differences between the anti-U1-RNP-positive individuals with/without anti-RNP70 in the SLE group. In conclusion, anti-RNP70 antibodies are not exclusive to MCTD but are rarely detected in pSS and healthy individuals. In SLE, anti-U1-RNP antibodies are associated with a clinical phenotype that resembles MCTD, with hematologic involvement and less damage accrual. Based on our results, the clinical value of subtyping anti-RNP70 in anti-U1-RNP-positive sera appears to be of limited value.

    General lifestyle factors explain young athletes’ mental health more than perceived coach autonomy support: a cross-sectional study on basketball players and gymnasts aged 10–222023Ingår i: BMJ Open Sport & Exercise Medicine, ISSN 2055-7647, artikel-id 9:e001648Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives This study described differences in lifestyle factors (sleeping problems/fatigue, pressure/activation), perceived coach autonomy support and  indicators of mental health (well-being and poor general mental health) across various age groups (children ≤12 years, youths 13–15 years, junior to senior ≥16 years) and sports (basketball and gymnastics). Second, the relationships between lifestyle factors and mental health indicators were explored, hypothesising that the relationships would be mediated by perceived coach autonomy support.

    Methods A cross-sectional study design was implemented by using an online survey which assessed lifestyle and environmental factors as well as mental health indicators. Participants were recruited through sports clubs in basketball and gymnastics. A total of 209 athletes (77 basketball players and 132 gymnasts) in the age range of 10–22 (median=13) years volunteered to complete the survey.

    Results Separate two-way analyses of variance showed significant main effects for age group on sleeping problems/fatigue, sleep quantity, pressure/activation, well-being and poor general mental health, with higher scores reported for older age groups of athletes. Path analysis displayed sleeping problems/fatigue and pressure/activation to significantly affect decreased well-being and poor general mental health; however, the relationships were not mediated by perceived coach autonomy support.

    Conclusion Lifestyle factors play a prominent role in mental health outcomes. Researchers studying athlete mental health should consider both general lifestyle and sports-related factors, considering developmental phases in the young athlete’s sporting context and overall life.

    Injury acknowledgement by reduction of sports load in world-leading athletics (track and field) athletes varies with their musculoskeletal health literacy and the socioeconomic environment2023Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 57, nr 13, s. 849-854Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective Although injury burden prompts elite athletics (track and field) athletes to engage in injury management, little is known about their health literacy. We investigated musculoskeletal (MS) health literacy in world-leading athletics athletes and associations with prechampionship injury acknowledgement by reduction of training load in different socioeconomic environments. Methods Adult and youth athletics athletes (n=1785) Methods Adult and youth athletics athletes (n=1785) preparing for World Championships were invited to complete the Literacy in Musculoskeletal Problems instrument and report acknowledgement of injury by reduction in training load during prechampionship tapering. Their socioeconomic standing was estimated through the Human Development Index of their home country. Demographic differences were examined using X-2 tests and determinants of injury acknowledgement assessed using logistic regression. Results Complete data were obtained from 780 athletes (43.7%) with 26% demonstrating sufficient MS health literacy, higher in adult (41%) than youth (13%) athletes (p<0.001). Adult athletes at the uppermost socioeconomic level showed higher MS health literacy than athletes at lower socioeconomic levels (p<0.001). At the uppermost socioeconomic level, adult athletes with sufficient MS health literacy had increased likelihood of acknowledging an injury by reduction in training load compared with peers demonstrating insufficient MS health literacy (OR=2.45; 95% CI 1.33-4.53). Athletes at middle socioeconomic levels with sufficient MS health literacy had decreased likelihood for acknowledging an injury during tapering (OR=0.29; 95% CI 0.11-0.78). Conclusions The prevalence of sufficient MS health literacy in world-leading athletics athletes is low. Associations between MS health literacy and injury acknowledgement in these athletes vary with the resourcefulness of the socioeconomic environment, implying that health literacy and resources for medical and performance support should be ascertained concurrently.

    Mental health, sleep, and pain in elite Para athletes and the association with injury and illness-A prospective study2023Ingår i: PM&R, ISSN 1934-1482, E-ISSN 1934-1563, Vol. 15, nr 9, s. 1130-1139Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    IntroductionThe interest in the health of Para athletes continues to increase. Still, there are few studies that have evaluated health parameters beyond injury and illness in this athlete population. ObjectiveTo assess (1) the weekly proportion of elite Para athletes reporting anxiety/depression, low sleep levels (<= 7 hours), and pain over 52 weeks; (2) and to explore whether these health parameters are associated with the risk for a sports injury or illness. DesignA 52-week prospective study, part of the Sports-related Injury and Illness in Paralympic Sport Study (SRIIPSS). SettingA total of 107 Swedish elite Para athletes with physical, visual, and intellectual impairment participated. Main outcome measuresData on self-reported anxiety/depression, sleep levels, pain, and injuries/illnesses were collected weekly. Comparisons of these parameters preceding an injury/illness were made using Friedmans analysis of variance (ANOVA). ResultsThe proportion of athletes reporting weekly anxiety/depression was 34.1%; 60.9% of athletes reported sleeping <= 7 hours and 49.9% reported pain. In exploratory analyses, there were no significant differences between weeks before an injury for any of the variables. There were significant differences in levels of sleep over the weeks, where sleep levels were significantly higher (>10 hours) 4 weeks prior to an illness (p = .016). ConclusionThis cohort of elite Para athletes reported relatively high levels of anxiety/depression, low sleep levels, and pain, which is a concern. High sleep levels and the risk for illness might be an indication of overtraining, which commonly leads to persistent fatigue and an increased susceptibility to infections. Monitoring of the health of elite Para athletes is recommended to be able to improve performance and health in this population.

    No concurrent correlations between parental mental state talk and toddlers language abilities2023Ingår i: Journal of Child Language, ISSN 0305-0009, E-ISSN 1469-7602Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Mental State Talk (MST) is utterances describing invisible mental aspects. The first aim of this study was to investigate the characteristics of Parental MST and Child MST and their concurrent association in a Swedish population, and the second aim was to relate these MST measures to the childrens general language abilities. Seventy-seven dyads of parents and their 25-month-old toddlers participated. MST was assessed by videotaping the dyads during free-play sessions in a laboratory and general language abilities were based on parental reports. Forty-nine toddlers did not produce MST, while all parents used MST. Child MST was positively associated with vocabulary and grammar. Parental MST was not associated with Child MST nor the childrens general language abilities. In exploratory analyses, Parental MST referred to another than the child was positively correlated with vocabulary and grammar. Further studies are needed to confirm these findings and continue studying MST in different linguistic contexts.

    Resilience in Swedish adolescents—Does resilience moderate the relationship between trauma experience and trauma symptoms?2023Ingår i: Psychological Trauma, ISSN 1942-9681, E-ISSN 1942-969X, Vol. Suppl 1, s. S125-S134Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Research shows child abuse to be devastating for psychological health, but children and adolescents display varying reactions from maltreatment. Resilience is known as a protective factor, but sparse research is conducted on adolescents or assess resilience with consideration of ecological theories. Adolescent Resilience Questionnaire (ARQ) was developed to assess the five dimensions: Individual, Family, Peers, School, and Community and covers the broader ecological resilience spectrum. Objective: As resilience is a part of the human being survival system we wanted to investigate if resilience measured with ARQ, could moderate associations between experiences of trauma and trauma symptoms. Method: Six hundred fifty adolescents between 15 and 17 years old were asked to complete the Linkoping Youth Life Experience Scale (LYLES), the Trauma Symptom Checklist for Children (TSCC), and the Adolescent Resilience Questionnaire (ARQ). Result: The results showed that high scores on any dimension of the ARQ were negatively associated with trauma symptoms and that the dimension Peers moderated the effect of trauma symptoms on both interpersonal traumatic events and adverse childhood circumstances for males. The dimension Family moderated the effect of trauma symptoms on noninterpersonal traumatic events for females. Conclusion: Resilience seems to be an important factor when it comes to evaluating posttraumatic symptoms and that different resilience factors have different meanings for different types of traumas as well for boys and girls.

    Risk factors for injury and illness in youth floorball players- A prospective cohort study2023Ingår i: Physical Therapy in Sport, ISSN 1466-853X, E-ISSN 1873-1600, Vol. 59, s. 92-102Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To investigate risk factors for injury and illness in female and male youth floorball players (12-17 years) during a 26-week floorball season. Design: Prospective cohort study. Setting: Recreational youth sport. Participants: 471 players (142 females) 12-17 years. Main outcome measures: Weekly survey including questions about stress, sleep quality, well-being, sport exposure and average weekly rating of perceived exertion (RPE). Acute:chronic workload ratio (ACWR) was calculated. The Oslo Sports Trauma Research Center questionnaire on health problems was used. Predictors of new injury and illness were examined using multi-level logistic regression models with weekly measures nested within individuals. Results: Higher stress, poorer sleep quality and well-being increased the odds of a new injury in the subsequent week by 8% (2.0-13.5%), 10% (4.2-15.9%) and 8% (2.4-13.5%) per 1 unit increase. Higher stress, and poorer well-being increased the odds of illness by 8% (2.6-12.6%), and 12% (7.2-16.6%). ACWR below 0.8 or above 1.3 increased the odds of illness by 34% (4.9-70.8%). Conclusions: Perceived stress, well-being, and sleep quality were associated with injury and illness occurrence in the subsequent week. ACWR outside the range 0.8-1.3 was associated with illness the subsequent week. Trial registration: Clinical Trials registration NCT03309904. (c) 2022 The Authors. Published by Elsevier Ltd.

    Time to workforce exit after a Parkinsons disease diagnosis2023Ingår i: NPJ PARKINSONS DISEASE, ISSN 2373-8057, Vol. 9, nr 1, artikel-id 72Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The impact of Parkinsons disease (PD) on workforce participation has received little attention even though demographic, lifestyle, and political changes together will result in an increased burden of PD on the working-age population. In this study, we investigate workforce survival after a PD diagnosis, as well as what demographic factors that are associated with workforce survival. As an exploratory outcome, we investigate workforce survival in persons with and without device-aided treatment (DAT). This is a nested case-cohort study based on Swedish national data from 2001-2016. Controls were matched on year of birth, sex, and municipality of residence. The used registers contain data on demographics, social insurance, in- and outpatient visits, filled drug prescriptions, and cause of death on the person-level. A total of 4781 persons with PD and 23,905 controls were included. The median survival until all-cause workforce exit was 43 months among persons that were workforce-active at the time of PD diagnosis, compared to 66 months in non-PD controls. Being female, >= 50 years old at diagnosis, or having a lower education were contributing factors to health-related workforce exit. Persons receiving DAT during follow-up exhibited shorter workforce survival than controls. However, this needs further investigation, particularly as patients have generally already left the workforce at the time for start of DAT. It is evident that PD has grave negative effects on workforce participation. Thus, supportive measures need to start at an early stage after diagnosis, and the development of new interventions is urgently needed.

    Universal prevention through a digital health platform reduces injury incidence in youth athletics (track and field): a cluster randomised controlled trial2023Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 57, nr 6, s. 364-371Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives To examine whether universal prevention via a digital health platform can reduce the injury incidence in athletics athletes aged 12-15 years and if club size had an influence on the effect of the intervention. Methods This was a cluster randomised trial where young athletics athletes were randomised through their club following stratification by club size into intervention (11 clubs; 56 athletes) and control (10 clubs; 79 athletes) groups. The primary endpoint was time from baseline to the first self-reported injury. Intervention group parents and coaches were given access to a website with health information adapted to adolescent athletes and were encouraged to log in and explore its content during 16 weeks. The control group continued training as normal. Training exposure and injury data were self-reported by youths/parents every second week, that is, eight times. The primary endpoint data were analysed using the log-rank test. Cox proportional hazards regression was used to analyse the second study aim with intervention status and club size included in the explanatory models. Results The proportion of completed training reports was 85% (n=382) in the intervention group and 86% (n=545) in the control group. The injury incidence was significantly lower (HR=0.62; chi(2)=3.865; p=0.049) in the intervention group. The median time to first injury was 16 weeks in the intervention group and 8 weeks in the control group. An interaction effect between the intervention and stratification factor was observed with a difference in injury risk between athletes in the large clubs in the intervention group versus their peers in the control group (HR 0.491 (95% CI 0.242 to 0.998); p=0.049). Conclusions A protective effect against injury through universal access to health information adapted for adolescent athletes was observed in youth athletics athletes. The efficacy of the intervention was stronger in large clubs.

    Autoantibodies associated with systemic sclerosis in three autoimmune diseases imprinted by type I interferon gene dysregulation: a comparison across SLE, primary Sjogrens syndrome and systemic sclerosis2022Ingår i: Lupus Science and Medicine, E-ISSN 2053-8790, Vol. 9, nr 1, artikel-id e000732Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    ObjectiveSLE, primary Sjogrens syndrome (pSS) and systemic sclerosis (SSc) are heterogeneous autoimmune diseases with a dysregulated type I interferon (IFN) system. The diseases often show overlapping clinical manifestations, which may result in diagnostic challenges. We asked to which extent SSc-associated autoantibodies are present in SLE and pSS, and whether these link to serum IFN-alpha, clinical phenotypes and sex. Samples with clinical data from patients with SSc and healthy blood donors (HBDs) served as controls. Finally, the diagnostic performance of SSc-associated autoantibodies was evaluated.MethodsSamples from well-characterised subjects with SLE (n=510), pSS (n=116), SSc (n=57) and HBDs (n=236) were analysed using a commercially available immunoassay (EuroLine Systemic Sclerosis Profile (IgG)). IFN-alpha was quantified by ELISA. Self-reported data on Raynauds phenomenon (RP) were available.ResultsWith exceptions for anti-Ro52/SSA and anti-Th/To, SSc-associated autoantibodies were more frequent in SSc than in SLE, pSS and HBDs regardless of sex. IFN-alpha levels correlated with the number of positive SSc-associated autoantibodies (r=0.29, p<0.0001) and associated with Ro52/SSA positivity (p<0.0001). By using data from SLE, SSc and HBDs, RP was significantly associated with topoisomerase I, centromere protein (CENP)-B, RNA polymerase III 11 kDa, RNA polymerase III 155 kDa and PM-Scl100 whereas Ro52/SSA associated inversely with RP. In SLE, CENP-A was associated with immunological disorder, CENP-B with serositis and Ku with lupus nephritis. By combining analysis of ANA (immunofluorescence) with SSc-associated autoantibodies, the diagnostic sensitivity reached 98% and the specificity 33%.ConclusionsThe 13 specificities included in the EuroLine immunoassay are commonly detected in SSc, but they are also frequent among individuals with other diseases imprinted by type I IFNs. These findings are valuable when interpreting serological data on patients with suspected SSc, especially as patients may present with disease manifestations overlapping different rheumatological diseases. In SLE, we observed associations between manifestations and SSc-associated autoantibodies which have not previously been reported.

    Design of the performance outcome scoring template (POS-T) with example application on CO2 emissions reduction amongst 36 OECD member countries2022Ingår i: Scientific Reports, E-ISSN 2045-2322, Vol. 12, nr 1, artikel-id 4404Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In applied program settings, such as in natural environment control and education, performance evaluation is usually conducted by evaluators considering both self-comparison and comparison with peers. We have developed the performance outcome scoring template (POS-T) for assessments with high face-validity in these settings. POS-T puts achievements of individuals or groups in context, i.e. the resulting performance outcome score (POS) reflects a meaningful measure of performance magnitude with regards to internal and external comparisons. Development of a POS is performed in four steps supported by a statistical framework. Software is supplied for creation of scoring applications in different performance evaluation settings. We demonstrate the POS-T by evaluation of CO2 emissions reduction amongst 36 OECD member countries.

    Effectiveness of the BNT162b2 mRNA Vaccine Compared with Hybrid Immunity in Populations Prioritized and Non-Prioritized for COVID-19 Vaccination in 2021-2022: A Naturalistic Case-Control Study in Sweden2022Ingår i: Vaccines, E-ISSN 2076-393X, Vol. 10, nr 8, artikel-id 1273Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The term hybrid immunity is used to denote the immunological status of vaccinated individuals with a history of natural infection. Reports of new SARS-CoV-2 variants of concern motivate continuous rethought and renewal of COVID-19 vaccination programs. We used a naturalistic case-control study design to compare the effectiveness of the BNT162b2 mRNA vaccine to hybrid immunity 180 days post-vaccination in prioritized and non-prioritized populations vaccinated before 31 July 2021 in three Swedish counties (total population 1,760,000). Subjects with a positive SARS-CoV-2 test recorded within 6 months before vaccination (n = 36,247; 6%) were matched to vaccinated-only controls. In the prioritized population exposed to the SARS-CoV-2 Alpha and Delta variants post-vaccination, the odds ratio (OR) for breakthrough infection was 2.2 (95% CI, 1.6-2.8; p < 0.001) in the vaccinated-only group compared with the hybrid immunity group, while in the later vaccinated non-prioritized population, the OR decreased from 4.3 (95% CI, 2.2-8.6; p < 0.001) during circulation of the Delta variant to 1.9 (95% CI, 1.7-2.1; p < 0.001) with the introduction of the Omicron variant (B.1.617.2). We conclude that hybrid immunity provides gains in protection, but that the benefits are smaller for risk groups and with circulation of the Omicron variant and its sublineages.

    Effects of mild-to-moderate sensorineuralhearing loss and signal amplification on vocalemotion recognition in middle-aged–olderindividuals2022Ingår i: PLOS ONE, E-ISSN 1932-6203, Vol. 17, nr 1, artikel-id e0261354Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Previous research has shown deficits in vocal emotion recognition in sub-populations of individuals with hearing loss, making this a high priority research topic. However, previousresearch has only examined vocal emotion recognition using verbal material, in which emotions are expressed through emotional prosody. There is evidence that older individualswith hearing loss suffer from deficits in general prosody recognition, not specific to emotionalprosody. No study has examined the recognition of non-verbal vocalization, which constitutes another important source for the vocal communication of emotions. It might be thecase that individuals with hearing loss have specific difficulties in recognizing emotionsexpressed through prosody in speech, but not non-verbal vocalizations. We aim to examinewhether vocal emotion recognition difficulties in middle- aged-to older individuals with sensorineural mild-moderate hearing loss are better explained by deficits in vocal emotion recognition specifically, or deficits in prosody recognition generally by including both sentencesand non-verbal expressions. Furthermore a, some of the studies which have concluded thatindividuals with mild-moderate hearing loss have deficits in vocal emotion recognition abilityhave also found that the use of hearing aids does not improve recognition accuracy in thisgroup. We aim to examine the effects of linear amplification and audibility on the recognitionof different emotions expressed both verbally and non-verbally. Besides examining accuracy for different emotions we will also look at patterns of confusion (which specific emotionsare mistaken for other specific emotion and at which rates) during both amplified and nonamplified listening, and we will analyze all material acoustically and relate the acoustic content to performance. Together these analyses will provide clues to effects of amplification onthe perception of different emotions. For these purposes, a total of 70 middle-aged-olderindividuals, half with mild-moderate hearing loss and half with normal hearing will perform acomputerized forced-choice vocal emotion recognition task with and without amplification

    Emotional Dysregulation and Trauma Symptoms Mediate the Relationship Between Childhood Abuse and Nonsuicidal Self-Injury in Adolescents2022Ingår i: Frontiers in Psychiatry, E-ISSN 1664-0640, Vol. 13, artikel-id 897081Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BackgroundNonsuicidal self-injury (NSSI) is common in adolescents. Emotion dysregulation has been identified as a core mechanism in the development and maintenance of NSSI and it is therefore an important target when addressing NSSI. The pathogenic connection between different kinds of childhood abuse, difficulties in emotion regulation and NSSI needs further investigation. The objective of this study was to examine whether difficulties with emotion regulation and trauma symptoms, separately and together, mediate the relationships between sexual, physical and emotional abuse and NSSI. MethodCross-sectional data was collected from 3,169 adolescent high-school students aged 16-19 years (M = 18.12, SD = 0.45). Data from self-reported experiences of childhood abuse, current difficulties with emotion regulation (measured with the Difficulties with Emotion Regulation Scale, DERS-16) and trauma symptoms (measured with the Trauma Symptom Checklist for Children, TSCC), and NSSI were collected. Structural Equation Modeling (SEM) was used to test the proposed relationships between variables. ResultsThe prevalence of life-time NSSI was 27.4%. Prevalence of reported childhood abuse was 9.2, 17.5, and 18.0% for sexual, physical, and emotional abuse, respectively. Childhood abuse, difficulties with emotion regulation and trauma symptoms exhibited significant positive associations with NSSI in adolescents. Emotional dysregulation and trauma symptoms were both found to mediate the relationship between childhood abuse and NSSI. Latent variable models were found to fit data well. ConclusionResults indicate that increased levels of emotional dysregulation and trauma symptoms in relation to childhood abuse contribute to the increased risk of NSSI. Further, results point to some aspects of emotional dysregulation and trauma symptoms being more important in this regard. Clinical implications are discussed.

    Nowcasting (Short-Term Forecasting) of COVID-19 Hospitalizations Using Syndromic Healthcare Data, Sweden, 20202022Ingår i: Emerging Infectious Diseases, ISSN 1080-6040, E-ISSN 1080-6059, Vol. 28, nr 3, s. 564-571Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We report on local nowcasting (short-term forecasting) of coronavirus disease (COVID-19) hospitalizations based on syndromic (symptom) data recorded in regular healthcare routines in Ostergotland County (population approximate to 465,000), Sweden, early in the pandemic, when broad laboratory testing was unavailable. Daily nowcasts were supplied to the local healthcare management based on analyses of the time lag between telenursing calls with the chief complaints (cough by adult or fever by adult) and COVID-19 hospitalization. The complaint cough by adult showed satisfactory performance (Pearson correlation coefficient r>0.80; mean absolute percentage error <20%) in nowcasting the incidence of daily COVID-19 hospitalizations 14 days in advance until the incidence decreased to <1.5/100,000 population, whereas the corresponding performance for fever by adult was unsatisfactory. Our results support local nowcasting of hospitalizations on the basis of symptom data recorded in routine healthcare during the initial stage of a pandemic.

    Objective Observer vs. Patient Motor State Assessments Using the PD Home Diary in Advanced Parkinsons Disease2022Ingår i: Frontiers in Neurology, E-ISSN 1664-2295, Vol. 13, artikel-id 935664Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The Parkinson Disease (PD) Home Diary (HD) is a commonly used clinical outcome measure, but it has not been extensively compared to direct assessments by experienced observers. Objective: Validation of patient-reported HD by investigating the agreement between motor state assessments by patients and observers. Methods: This observational study included patients with PD and motor fluctuations. Observers were physicians or research nurses. Patients completed a screening visit, one day of diary ratings at home, and then two days of ratings on-site during which patients and observers simultaneously judged the participants motor state. Results: Observers and 40 patients completed 1,288 pairs of half-hourly blinded motor state assessments. There were significant differences between observer and patient ratings (P < 0.001) and the temporal agreement was poor (Cohens kappa = 0.358). The agreement between patient and observer ratings was 71.1% for observed "On without dyskinesia", 57.3% for observed "Off", and 49.4% for observed "On with dyskinesia". Daily times spent in the three motor states as aggregated diary data showed fair to excellent reliability with intraclass coefficient values ranging from 0.45 to 0.52 for "On" and 0.77 for "Off". Conclusion: There were significant differences between observer and patient ratings. Patients and observers generally agreed on when the patients was in the "On" state (with or without dyskinesia). Patient ratings on the hour level seem to be influenced by other aspects of the patients experience than the observed motor state, but assessment of daily time spent in the different motor state provides reasonable reliability.

    Psychometric properties of the Adolescent Resilience Questionnaire (ARQ) in a sample of Swedish adolescents2022Ingår i: BMC Psychiatry, E-ISSN 1471-244X, Vol. 22, nr 1, artikel-id 468Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    The importance of resilience, and interest in it, has increased markedly in recent years, based on the need to understand why some children and young people have a resilience to stress that others lack. At the same time, there has been a lack of instruments to measure resilience. The aim of this study was to translate the Adolescent Resilience Questionnaire (ARQ) into Swedish and investigate the psychometrics of this Swedish version.

    Methods

    A normative sample of 616 students aged 15-17 was recruited through the school system in five different communities. Students filled out a digitalised composite form consisting of ARQ and three other standardised questionnaires, the Sense of Coherence Scale-13 (Soc-13), the Rosenberg Self-Esteem Scale (RSES) and the Relationship Questionnaire (RQ).

    Results

    The ARQ, with five domains and twelve subscales, showed good alpha coefficients alpha = .95 for the total scale and subscales ranging between alpha = .70 to .91, except for the subscales Emotional insight (alpha = 0.69) and Empathy/Tolerance (alpha = .61). The convergent validity, which was tested for the first time in this study, was good, especially with the Internal Domain for both SOC-13 and RSES. The confirmatory factor analysis showed a satisfactory construct validity. Finally, some gender differences were seen, with boys scoring higher on the total ARQ scale.

    Conclusion

    The study shows that the Swedish translation of ARQ has satisfactory psychometric properties. The ARQ could therefore be used as a tool for adolescents when evaluating the importance of resilience.

    Traces of pornography: Shame, scripted action, and agency in narratives of young Swedish women2022Ingår i: Sexuality & Culture, ISSN 1095-5143, E-ISSN 1936-4822, Vol. 26, s. 1819-1939Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The purpose of this study was to explore young women's experiences of pornography and how they believe pornography has affected both themselves and other adolescents in terms of sexuality and sexual experiences. Seven young women aged 17-18 years were interviewed and their narratives were analyzed through thematic analysis. The results show that the participants' pornography consumption has at times evoked feelings of shame in relation to their official feminist stance. Moreover, they all report experiences of being pressured to adopt a "supporting role" in sex and to perform in line with a narrow pornographic script, thus compromising their wish to enjoy sex and enact sexual agency. It is also evident how the participants have struggled to navigate through the conflicting positions that are available within a postfeminist culture, for instance in relation to feminism, heterosexual gender norms, and the strong ideal of being an "agent" in sex. In the pursuit of young women's healthy sexual development, the results highlight the need for safe female venues, a relational understanding of agency, cultural change rather than individualized responsibility, porn literacy training, and the advancement of broader sexual scripts.

    Vulnerability and stressors on the pathway to depression in a global cohort of young athletics (track and field) athletes2022Ingår i: Scientific Reports, E-ISSN 2045-2322, Vol. 12, nr 1, artikel-id 7901Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This research set out to identify pathways from vulnerability and stressors to depression in a global population of young athletes. Retrospective data were collected at age 18-19 years from Athletics athletes (n = 1322) originating from Africa, Asia, Europe, Oceania, and the Americas. We hypothesised that sports-related and non-sports-related stressors in interaction with structural vulnerability instigate depression. Path modelling using Maximum likelihood estimation was employed for the data analysis. Depression caseness and predisposition were determined using the WHO-5 instrument. Thirty-six percent of the athletes (n = 480) returned complete data. Eighteen percent of the athletes reported lifetime physical abuse, while 11% reported sexual abuse. Forty-five percent of the athletes had recently sustained an injury. The prevalence of depression caseness was 5.6%. Pathways to depression caseness were observed from female sex (p = 0.037) and injury history (p = 0.035) and to predisposition for depression also through exposure to a patriarchal society (p = 0.046) and physical abuse (p < 0.001). We conclude that depression in a global population of young athletes was as prevalent as previously reported from general populations, and that universal mental health promotion in youth sports should include provision of equal opportunities for female and male participants, injury prevention, and interventions for abuse prevention and victim support.

    Assessing parents, youth athletes and coaches subjective health literacy: A cross-sectional study2021Ingår i: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861, Vol. 24, nr 7, s. 627-634Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: The aim was to describe levels of subjective Health Literacy (HL), and to examine possible differences in prevalence proportions between sexes, age groups and level of educations among youth athletes and their mentors (coaches, parents/caregivers) in Swedish Athletics. Design: Cross-sectional. Methods: Data on subjective HL were collected using the Swedish Communicative and Critical Health Literacy (S-CCHL) instrument for mentors and for youth the School-Aged Children (HLSAC) instrument. Questions assessing mentors literacy on sports injury and return to play were also included. Results: The surveys were completed by 159 (91%) mentors and 143 youth athletes (87%). The level of S-CCHL was sufficient in 53% of the mentors. Of youth athletes, 28% reported a high level of HL and the item with least perceived high HL (21%) was critical thinking. Ninety-four percent of the mentors believed that it is quite possible to prevent injuries in athletics and 53% perceived having a very good knowledge about how to prevent injuries. Forty-six percent of the mentors perceived having a very good knowledge of return to sport criteria. Conclusions: The level of health literacy was low with about half of the mentors and one out of three youth athletes having adequate HL levels. Only half of the mentors stated having a good knowledge of various injury prevention strategies. To reduce health consequences in youth sport and enable talent development more work is needed to understand the facilitators and barriers for the uptake of various health promotion and injury prevention strategies.

    Lifetime Prevalence of Verbal, Physical, and Sexual Abuses in Young Elite Athletics Athletes2021Ingår i: Frontiers in Sports and Active Living, E-ISSN 2624-9367, Vol. 3, artikel-id 657624Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To examine prevalence of verbal, physical, and sexual abuses in young elite athletes, a cross sectional questionnaire-based survey was conducted during the World Athletics under 20 World Championships. This questionnaire aimed at distinguishing between abuses perpetrated in the context of Athletics from those which were unrelated to Athletics. Four hundred and eighty athletes (52.3%, male) from North America, South America, Europe, Africa, Asia, and Oceania took part in the electronic anonymous survey. Outside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and sexual abuses. However, 45 males (18% of the male population) and 34 females (15% of the female population) athletes reported sexual abuse. Asian athletes reported a slightly higher rate of sexual abuse; three quarters of them being non-touching abuses. Inside Athletics setting, no gender difference was found for the prevalence of verbal, physical, and non-touching sexual abuses. However, 58 males (23%) and 47 females (21%) reported verbal abuses. Thirty-one males (12%) and 20 females (9%) reported physical abuses, whereas 30 males (12%) and 17 females (7%) reported sexual abuses. Physical abuses were slightly more frequent in Asia and in Africa and less frequent in South America. Sexual abuses inside Athletics also differed over regions, and were unexpectedly twice more frequent than expected in Asia and slightly less frequent than expected in Europe. Friends and partners were identified as the more frequent (&gt; 50%) abusers outside or inside the Athletics settings, whereas outside Athletics and inside Athletics, coaches were identified as sexual abuse perpetrators in 8 and 25% of cases, respectively. The prevalence of verbal, physical, or sexual abuses is high but consistent with what has been reported in United Kingdom, Norway, Canada, and Sweden at national level in recreational or elite athletes. Sexual abuse, including touching or penetrative abuses, occurred significantly more often in male athletes when compared to female athletes. This finding invites healthcare and social workers, and policymakers to also consider the risk of sexual abuse of young male athletes in Athletics. These results also call for longitudinal studies on young elite athletes.

    Predictors of Sickness Absence in a Clinical Population With Chronic Pain2021Ingår i: Journal of Pain, ISSN 1526-5900, E-ISSN 1528-8447, Vol. 22, nr 10, s. 1180-1194Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Chronic pain-related sickness absence is an enormous socioeconomic burden globally. Optimized interventions are reliant on a lucid understanding of the distribution of social insurance benefits and their predictors. This register-based observational study analyzed data for a 7-year period from a population-based sample of 44,241 chronic pain patients eligible for interdisciplinary treatment (IDT) at specialist clinics. Sequence analysis was used to describe the sickness absence over the complete period and to separate the patients into subgroups based on their social insurance benefits over the final 2 years. The predictive performance of features from various domains was then explored with machine learning-based modeling in a nested cross-validation procedure. Our results showed that patients on sickness absence increased from 17% 5 years before to 48% at the time of the IDT assessment, and then decreased to 38% at the end of follow-up. Patients were divided into 3 classes characterized by low sickness absence, sick leave, and disability pension, with eight predictors of class membership being identified. Sickness absence history was the strongest predictor of future sickness absence, while other predictors included a 2008 policy, age, confidence in recovery, and geographical location. Information on these features could guide personalized intervention in the specialized healthcare. PERSPECTIVE: This study describes sickness absence in patients who visited a Swedish pain specialist interdisciplinary treatment clinic during the period 2005 to 2016. Predictors of future sickness absence are also identified that should be considered when adapting IDT programs to the patient's needs.

    Suicidal thoughts (ideation) among elite athletics (track and field) athletes: associations with sports participation, psychological resourcefulness and having been a victim of sexual and/or physical abuse2021Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 55, nr 4, s. 198-205Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective To examine associations between suicidal ideation and sexual and physical abuse among active and recently retired elite athletics (track and field) athletes. Methods The study population consisted of all athletes (n=402) selected for a Swedish Athletics team between 2011 and 2017. Data on suicidal ideation, suicidal events (estimated through the 1 year nonsports injury prevalence), lifetime abuse experiences, sociodemographics, sense of coherence and coping strategies were collected using a cross-sectional survey. The data were analysed using binary logistic regression with suicidal ideation and non-sports injury as outcomes. Results 192 athletes (47.8%) returned data. The prevalence of suicidal ideation was 15.6% (men 17.4%; women 14.2%) and the non-sports injury prevalence was 8.0% (men 11.6%; women 5.7%). Among women, suicidal ideation was associated with having been sexually abused (OR 5.94, 95% CI 1.42 to 24.90; p=0.015) and lower sense of coherence (OR 0.90, 95% CI 0.85 to 0.96; p=0.001) (Nagelkerke R-2 =0.33). Among men, suicidal ideation was only associated with use of behavioural disengagement for coping (OR 1.51, 95% CI 1.18 to 1.95; p=0.001) (R-2=0.25). Among women, non-sports injury prevalence was associated with having been sexually abused (OR 8.61, 95% CI 1.34 to 55.1; p=0.023) and participating in an endurance event (OR 7.37, 95% CI 1.11 to 48.9; p=0.039 (R-2 =0.23), while among men, having immigrant parents (OR 5.67, 95% CI 1.31 to 24.5; p=0.020) (R-2=0.11) was associated with injury outside sports. Conclusions About one out of six international athletics athletes reported having experienced suicidal ideation. World Athletics and National Olympic Committees need to include suicide prevention in their athlete protection programmes.

    The role of support from significant others in the association between disease-related factors and sickness absence in early rheumatoid arthritis: a longitudinal study2021Ingår i: Scandinavian Journal of Rheumatology, ISSN 0300-9742, E-ISSN 1502-7732, Vol. 50, nr 6, s. 427-434Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aim of this study was to analyse how support from significant others affects the associations between disease-related variables and sickness absence during the first 2 years after rheumatoid arthritis (RA) diagnosis. Method: Data from 274 people with RA (73% women) of working age (18-63 years) were retrieved from the Swedish early RA cohort TIRA-2. These data concerned disease-related variables (disease activity, activity limitations, pain intensity, and grip force), sickness absence, and perceived support from significant others. Associations of disease-related variables with sickness absence and how these associations were moderated by support from significant others were analysed using zero-inflated negative binomial regression. Results: During the 2 years after diagnosis, higher disease activity was significantly associated with increased odds of sickness absence, a connection strengthened by perceived support from family during the first year. More perceived support was also directly and significantly associated with increased odds of sickness absence during the first year. Conclusions: Support from significant others is related to sickness absence in RA, specifically during the first year after diagnosis. Although patients report high levels of support from significant others, this does not necessarily lead to more positive work outcomes. Therefore, it is important to consider other aspects of support that might influence work outcomes, e.g. type and quality of support. Future research should investigate these forms of support, and when significant others should be encouraged to support in the rehabilitation process to increase the chances of people with RA having a well-functioning and sustainable work life.

    The value of interdisciplinary treatment for sickness absence in chronic pain: A nationwide register-based cohort study2021Ingår i: European Journal of Pain, ISSN 1090-3801, E-ISSN 1532-2149, Vol. 25, nr 10, s. 2190-2201Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Interdisciplinary treatment (IDT) is an internationally recommended intervention for chronic pain, despite inconclusive evidence of its effects on sickness absence. Methods With data from 25,613 patients in Swedish specialist healthcare, we compared sickness absence, in the form of both sick leave and disability pensions, over a 5-year period between patients either allocated to an IDT programme or to other/no interventions (controls). To obtain population-average estimates, a Markov multistate model with theory-based inverse probability weights was used to compute both the proportion of patients on sickness absence and the total sickness absence duration. Results IDT patients were more likely than controls to receive sickness absence benefits at any given time (baseline: 49% vs. 46%; 5-year follow-up: 36% vs. 35%), and thereby also had a higher total duration, with a mean (95% CI) of 67 (87, 48) more days than controls over the 5-year period. Intriguingly, sick leave was higher in IDT patients (563 [552, 573] vs. 478 [466, 490] days), whereas disability pension was higher in controls (152 [144, 160] vs. 169 [161, 178] days). Conclusion Although sickness absence decreased over the study period in both IDT patients and controls, we found no support for IDT decreasing sickness absence more than other/no interventions in chronic pain patients. Significance In this large study of chronic pain patients in specialist healthcare, sickness absence is compared over a 5-year period between patients in an interdisciplinary treatment programme and other/no interventions. Sickness absence decreased over the study period in bothgroups; however, there was no support forthat it decreased more with interdisciplinary treatment than alternative interventions.

    Usefulness of Clinical and Laboratory Criteria for Diagnosing Autoimmune Liver Disease among Patients with Systemic Lupus Erythematosus: An Observational Study2021Ingår i: Journal of Clinical Medicine, E-ISSN 2077-0383, Vol. 10, nr 17, artikel-id 3820Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Abnormal liver function tests are frequently observed during follow-up of patients with systemic lupus erythematosus (SLE) but data on co-existence with autoimmune liver diseases (AILD) are scarce. This retrospective study aimed to describe the prevalence of autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) among well-characterized subjects with SLE. We also evaluated whether the presence of autoantibodies to complement protein 1q (C1q) and/or ribosomal P protein (anti-ribP) are, directly or inversely, associated with AIH, as proposed in some reports. The number of screened patients was 287 (86% females), and all cases were included in a regional Swedish cohort. Each subject of the study population met the 1982 American College of Rheumatology classification criteria and/or the Fries diagnostic principle. By applying the simplified diagnostic AIH criteria combined with persistent transaminasemia, 40 (13.9%) cases reached at least "probable AIH". However, merely 8 of these had been diagnosed with AIH (overall AIH prevalence 2.8%). Neither anti-C1q nor anti-ribP associated significantly with AIH. By applying the recent PBC guidelines, 6 (2.1%) cases were found, but only 3 of them had actually been diagnosed with PBC and one additional subject was not identified by the guidelines (overall PBC prevalence 1.4%). Compared to prevalence data from the general Swedish population, both AIH and PBC were highly overrepresented in our study population. The sensitivity of the diagnostic AIH criteria was impeccable but the specificity was less impressive, mainly due to positive ANA and hypergammaglobulinemia. Based on our findings, among subjects with SLE, the AIH criteria are less useful and liver biopsy combined with detection of other AILD-associated autoantibodies should be performed.

    Efficacy of pre-participation cardiac evaluation recommendations among athletes participating in World Athletics Championships2020Ingår i: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 27, nr 14, s. 1480-1490Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Athletes competing in athletics (track and field) at international level may be participating with underlying undiagnosed life-threatening cardiovascular conditions. Our objective was to analyse variations in pre-participation cardiac evaluation prevalence among athletes participating in two International Association of Athletics Federations (IAAF) World Athletics Championships, with regard to the human developmental level and global region of their home countries, as well as athletes’ age category, gender, event group and medical insurance type.

    Design Cross-sectional web-based survey.MethodsA total of 1785 athletes competing in the IAAF World Under 18 Championships Nairobi 2017 and World Championships London 2017 were invited to complete a pre-participation health questionnaire investigating the experience of a pre-participation cardiac examination.

    Results A total of 704 (39%) of the athletes participated. Among these, 59% (60% of women; 58% of men) reported that they had been provided at least one type of pre-participation cardiac evaluation. Athletes from very high income countries, Europe and Asia, showed a higher prevalence of at least one pre-participation cardiac evaluation.

    Conclusions The prevalence of pre-participation cardiac evaluation in low to middle income countries, and the African continent in particular, needs urgent attention. Furthermore, increases in evaluation prevalence should be accompanied by the development of cost-effective methods that can be adopted in all global regions.

    Health complaints and heat stress prevention strategies during taper as predictors of peaked athletic performance at the 2015 World Athletics Championship in hot conditions2020Ingår i: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861, Vol. 23, nr 4, s. 336-341, artikel-id S1440-2440(19)30893-XArtikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: To investigate whether self-reported health complaints and choice of heat stress prevention strategies during the taper predicted peaking at an athletics championship in hot conditions.

    DESIGN: Cohort study.

    METHODS: Data on health and heat stress prevention were collected before the 2015 World Athletics Championship in Beijing, China. Peaking was defined using the athlete's pre-competition ranking and final competition rank. Baseline and endpoint data were fitted into multiple logic regression models.

    RESULTS: Two hundred forty-five (29%) of 841 eligible athletes participated. Both sprint/power (Odds ratio (OR) 0.33 (95% Confidence interval (CI) 0.11 to 0.94), P=0.038) and endurance/combined events (OR 0.38 (95% CI 0.14 to 1.00), P=0.049) athletes having sustained concern-causing health complaints during the taper were less likely to peak. Endurance/combined events athletes who chose pre-cooling to mitigate heat stress were less likely to peak (OR 0.35 (95% CI 0.15 to 0.80), P=0.013), while sprint/power athletes reporting a sudden-onset injury complaint during the taper displayed increased peaking (OR 4.47 (95% CI 1.28 to 15.59), P=0.019).

    CONCLUSIONS: Health complaints that caused the athlete concern during the taper were predictive of failure to peak at a major athletics competition. Sprint/power athletes who experienced an acute injury symptom during the taper appeared to benefit from rest. Pre-cooling strategies seem to require further validation during real-world endurance/combined events. It appears that athletics athletes' self-reported health should be monitored during the taper, concerns addressed, and heat stress prevention strategies individually tested before championships in hot conditions.

    Injuries and illnesses in Swedish Paralympic athletes-A 52-week prospective study of incidence and risk factors2020Ingår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 30, nr 8, s. 1457-1470Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction Sports-related injuries and illnesses in Paralympic sport (SRIIPS) are a concern, but knowledge about the etiology and risk factors is limited. The aim of this study was to describe the annual incidence, type, and severity of injuries and illnesses among Swedish Paralympic athletes and to assess risk factors. Methods Swedish Paralympic athletes (n = 107) self-reported SRIIPS every week during 52 weeks using an eHealth application. Incidence proportions (IP) and incidence rates (IR) were used as measures of disease burden. Time-to-event methods (Kaplan-Meier and Cox regression) were used to identify risk factors. Results The annual IP for injury was 68% and for illness 77%. The injury IR was 6.9/1000 hours and the illness IR 9.3/1000 hours. The median time to injury was 19 weeks (95% CI: 10.5-27.4) and to illness 9 weeks (95% CI: 1.4-16.6). Most injuries occurred during training, and 34% were classified as severe (&gt;= 21 days of time loss). An increased injury risk was observed among athletes in team sports (HR 1.88; 95% CI: 1.19-2.99), athletes with a previous severe injury (HR 2.37; 95% CI: 1.47-3.83), and male athletes (HR 1.76; 95% CI: 1.06-2.93). The most common illness type was infection (84%). Athletes in team sports (HR 1.64; 95% CI: 1.05-2.54) and males with a previous illness (HR = 2.13; 95% CI: 1.04-4.36) had a higher illness risk. Conclusion Paralympic athletes report a high incidence of injuries and illnesses over time. This emphasizes the need to develop preventive strategies of SRIIPS and optimize medical services for this heterogeneous athlete population.

    Longitudinal anti-nuclear antibody (ANA) seroconversion in systemic lupus erythematosus: a prospective study of Swedish cases with recent-onset disease2020Ingår i: Clinical and Experimental Immunology, ISSN 0009-9104, E-ISSN 1365-2249, Vol. 199, nr 3, s. 245-254Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Serum immunoglobulin (Ig)G anti-nuclear antibodies (ANA) detected by indirect immunofluorescence (IF) microscopy remains a hallmark of systemic lupus erythematosus (SLE). Whether or not IF-ANA status varies over time is controversial. We therefore designed a prospective study with longitudinal follow-up of patients with recent-onset SLE. The study population consisted of 54 recently diagnosed SLE cases, all meeting the 1982 American College of Rheumatology (ACR) and/or the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria. Clinical follow-up data, including disease activity, organ damage and sera, were collected from clinical onset of SLE and onwards, in most cases yearly (0-96 months). IF-ANA was analysed on human epithelial cells-2 (HEp-2) cells and categorized regarding staining patterns. Using an addressable laser bead assay (FIDIS (TM) Connective profile), we measured IgG-ANA fine specificities against Ro52/SSA, Ro60/SSA, Sjogrens syndrome type B antigen (La/SSB), Smith antigen (Sm), Smith antigen/ribonucleoprotein (Sm/RNP), U1 RNP (U1RNP), dsDNA, ribosomal-P protein and histone. At baseline, all patients were judged ANA-positive at an abnormal titre corresponding to the 95th percentile of healthy blood donors, but seven of 54 patients (13%) lost ANA-positivity over time. Homogeneous (AC-1; 46%) and speckled (AC-4 or 5; 31%) were the most frequently observed patterns at inclusion, whereas 7% switched pattern at least once during follow-up. Established associations between ANA fine specificities and clinical data were confirmed. Levels of anti-Sm/RNP, but not of anti-dsDNA, correlated with clinical disease activity [modified SLE disease activity 2000 (mSLEDAI-2K)]. Our data indicate that a considerable proportion of Swedish patients with SLE lose ANA-positivity over time, whereas consistent staining patterns were frequent. The clinical and mechanistic relevance of ANA seroconversion remains uncertain. Further prospective evaluations in larger SLE populations with more diverse ethnicities are warranted.

    Nowcasting (Short Term Forecasting) of Influenza Epidemics in Local Settings, Sweden, 2008-20192020Ingår i: Emerging Infectious Diseases, ISSN 1080-6040, E-ISSN 1080-6059, Vol. 26, nr 11, s. 2669-2677Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The timing of influenza case incidence during epidemics can differ between regions within nations and states. We conducted a prospective 10-year evaluation (January 2008-February 2019) of a local influenza nowcasting (short-term forecasting) method in 3 urban counties in Sweden with independent public health administrations by using routine health information system data. Detection-of-epidemic-start (detection), peak timing, and peak intensity were nowcasted. Detection displayed satisfactory performance in 2 of the 3 counties for all nonpandemic influenza seasons and in 6 of 9 seasons for the third county. Peak-timing prediction showed satisfactory performance from the influenza season 2011-12 onward. Peak-intensity prediction also was satisfactory for influenza seasons in 2 of the counties but poor in 1 county. Local influenza nowcasting was satisfactory for seasonal influenza in 2 of 3 counties. The less satisfactory performance in 1 of the study counties might be attributable to population mixing with a neighboring metropolitan area.

    Abstract [en]

    BackgroundWith increased participation in Paralympic sports, the burden of sports-related injuries and illnesses may increase. However, there is limited knowledge about the epidemiology of sports-related injuries and illnesses in Paralympic sports (SRIIPS). ObjectiveTo describe among Swedish Paralympic athletes the 1-year retrospective period prevalence of severe SRIIPS and the point prevalence of all SRIIPS and to examine differences in prevalence proportions between athletes with different impairments, behaviors, and sport characteristics. DesignCross-sectional study. SettingSwedish Paralympic Programme. ParticipantsOne hundred and four Paralympic athletes with visual, physical, and intellectual impairment. MethodsAn eHealth application adapted to Paralympic athletes was used to collect self-report data on existing and previous SRIIPS, as well as impairment, behavior, and sport characteristics. Main Outcome MeasurementsOne-year retrospective period prevalence and point prevalence. ResultsThe period prevalence of severe injuries was 31% (95% CI 23-40) and the point prevalence 32% (95% CI 24-41). The period prevalence of severe illnesses was 14% (95% CI 9-23), and 13% of the athletes (95% CI 8-22) reported a current illness. More severe injuries (Pamp;lt;.05) were reported by athletes aged 18 to 25years, not using assistive device, having pain during sport, using analgesics, continuing training injured, and feeling guilt when missing exercise. Athletes who reported a previous severe injury, having pain in daily life and during sport, using analgesics, and being upset when unable to exercise had a higher prevalence of current injuries (Pamp;lt;.05). Being female, reporting previous severe illness, using prescribed medication, and feeling anxious/depressed were features associated with ongoing illnesses (Pamp;lt;.05). ConclusionParalympic athletes report a high prevalence of SRIIPS. Behavioral and psychological aspects as well as pain and use of medication appear to be associated with the occurrence of SRIIPS. The results imply that factors leading to SRIIPS are complex and call for a broad biopsychosocial approach when developing preventive measures. Level of EvidenceIII.

    Abstract [en]

    SYNOPSIS: High-quality sports injury research can facilitate sports injury prevention and treatment. There is scope to improve how our field applies best-practice methods-methods matter (greatly!). The first METHODS MATTER meeting, held in January 2019 in Copenhagen, Denmark, was the forum for an international group of researchers with expertise in research methods to discuss sports injury methods. We discussed important epidemiological and statistical topics within the field of sports injury research. With this opinion document, we provide the main take-home messages that emerged from the meeting. Meeting participants agreed that the definition of sport injury depends on the research question and context. It was considered essential to be explicit about the goal of the research effort and to use frameworks to illustrate the assumptions that underpin measurement and the analytical strategy. Complex systems were discussed to illustrate how potential risk factors can interact in a nonlinear way. This approach is often a useful alternative to identifying single risk factors. Investigating changes in exposure status over time is important when analyzing sport injury etiology, and analyzing recurrent injury, subsequent injury, or injury exacerbation remains challenging. The choice of statistical model should consider the research question, injury measure (eg, prevalence, incidence), type and granularity of injury data (categorical or continuous), and study design. Multidisciplinary collaboration will be a cornerstone for future high-quality sport injury research. Working outside professional silos in a diverse, multidisciplinary team benefits the research process, from the formulation of research questions and designs to the statistical analyses and dissemination of study results in implementation contexts. This article has been copublished in the British Journal of Sports Medicine and the Journal of Orthopaedic & Sports Physical Therapy.

    The Influence of Form- and Meaning-Based Predictions on Cortical Speech Processing Under Challenging Listening Conditions: A MEG Study2020Ingår i: Frontiers in Neuroscience, ISSN 1662-4548, E-ISSN 1662-453X, Vol. 14, artikel-id 573254Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Under adverse listening conditions, prior linguistic knowledge about the form (i.e., phonology) and meaning (i.e., semantics) help us to predict what an interlocutor is about to say. Previous research has shown that accurate predictions of incoming speech increase speech intelligibility, and that semantic predictions enhance the perceptual clarity of degraded speech even when exact phonological predictions are possible. In addition, working memory (WM) is thought to have specific influence over anticipatory mechanisms by actively maintaining and updating the relevance of predicted vs. unpredicted speech inputs. However, the relative impact on speech processing of deviations from expectations related to form and meaning is incompletely understood. Here, we use MEG to investigate the cortical temporal processing of deviations from the expected form and meaning of final words during sentence processing. Our overall aim was to observe how deviations from the expected form and meaning modulate cortical speech processing under adverse listening conditions and investigate the degree to which this is associated with WM capacity. Results indicated that different types of deviations are processed differently in the auditory N400 and Mismatch Negativity (MMN) components. In particular, MMN was sensitive to the type of deviation (form or meaning) whereas the N400 was sensitive to the magnitude of the deviation rather than its type. WM capacity was associated with the ability to process phonological incoming information and semantic integration.

    Injury Pain in Track and Field Athletes: Cross-Sectional Study of Mediating Factors2019Ingår i: SPORTS, ISSN 2075-4663, Vol. 7, nr 5, artikel-id 110Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This exploratory study aimed to investigate whether data from track and field athletes support a conceptual model where the perception of pain affects self-evaluated health directly, yet is also indirectly mediated through personal factors and external stressors. A cross-sectional study was performed among athletes (n = 278) competing at the highest national level in the sport. Data for the dependent and independent variables were collected using the EuroQol-5 dimensions (EQ-5D) standardized measure of health status, and the mediator variables were collected by the Body Consciousness Scale (BCS-HA), Perceived Motivational Climate in Sport Questionnaire (PMCSQ), Commitment to Exercise Scale (CtES), and Brief Cope survey instruments. Two hundred and twenty-five (81%) athletes provided complete data sets. A strong direct association (c = -16.49; p amp;lt; 0.001) was found between pain and self-estimated health, and a global mediation was found through the mediators (mediation effect (ME), -1.814, 90% confidence interval (CI), -3.414, -0.351). Specific mediation was observed for body competence (ME, -0.721; 90% CI, -2.028, -0.097) and private body consciousness (ME, -0.514; 90% CI, -1.761, -0.017). In conclusion, we found a negative association between perceived pain and self-evaluated health among competitive track and field athletes, and we found that a portion of the association was mediated through mediating factors. Under the assumption that the analyzed pain data primarily represented noxious pain, the conceptual model of the relationships between pain and self-estimated health among high-level track and field athletes was supported.

    Lifetime history of sexual and physical abuse among competitive athletics (track and field) athletes: cross sectional study of associations with sports and non-sports injury2019Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 53, nr 22, s. 1412-1417Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective To examine associations between lifetime sexual and physical abuse, and the likelihood of injury within and outside sport in athletes involved in competitive athletics.

    Methods A cross sectional study was performed among the top 10 Swedish athletics athletes using 1 year prevalence of sports and non-sports injuries as the primary outcome measure. Associations with sociodemographic characteristics, lifetime abuse history and training load were investigated. Data were analysed using simple and multiple logistic regression models.

    Results 11% of 197 participating athletes reported lifetime sexual abuse; there was a higher proportion of women (16.2%) than men (4.3%) (P=0.005). 18% reported lifetime physical abuse; there was a higher proportion of men (22.8%) than women (14.3%) (P=0.050). For women, lifetime sexual abuse was associated with an increased likelihood of a non-sports injury (OR 8.78, CI 2.76 to 27.93; P<0.001). Among men, increased likelihood of a non-sports injury was associated with more frequent use of alcoholic beverages (OR 6.47, CI 1.49 to 28.07; P=0.013), while commencing athletics training at >13 years of age was associated with a lower likelihood of non-sports injury (OR 0.09, CI 0.01 to 0.81; P=0.032). Lifetime physical abuse was associated with a higher likelihood of sports injury in women (OR 12.37, CI 1.52 to 100.37; P=0.019). Among men, athletes with each parents with ≤12 years formal education had a lower likelihood of sustaining an injury during their sports practice (OR 0.37, CI 0.14 to 0.96; P=0.040).

    Conclusions Lifetime sexual and physical abuse were associated with an increased likelihood of injury among female athletes. Emotional factors should be included in the comprehension of injuries sustained by athletes.

    Maintaining motivation and health among recreational runners: Panel study of factors associated with self-rated performance outcomes at competitions2019Ingår i: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861, Vol. 22, nr 12, s. 1319-1323Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To investigate health-related factors associated with self-rated race performance outcomes among recreational long-distance runners. Design: Panel study. Methods: Data were collected from runners one month before and after a community-level race event including distances from 8 to 42.2 km. The primary outcome measure was self-rated race performance outcome. The explanatory variables represented health complaints suffered during the build-up year, the pre-race month, and the race and among full marathon runners predicted objective performance outcome (mean pace equal to training pace or faster). Multiple logistic regression was used to determine factors associated with the self-rated performance outcome. Results: Two-hundred forty-five runners (29%) provided complete data sets. Seventy-four percent of the runners reached their desired race performance outcome. Achievement of the performance outcome was more likely when having avoided illness during the build-up and pre-race periods (OR = 3.8; 95% CI:1.8-8.0, p amp;lt; 0.001), having avoided per-race injury (OR=3.0; 95% CI:1.2-7.4, p = 0.02) and avoided perrace illness (OR= 4.1; 95% CI:1.3-15, p = 0.020). Having obtained the self-rated performance outcome was also associated with running a shorter distance (OR=3.6; 95% CI: 1.7-8.0,p = 0.001) and being younger than 50 years of age (OR= 2.4; 95% CI:1.1-5.3-8.3, p = 0.03). Having met the predicted objective performance outcome predisposed marathon runners to also obtain the self-rated performance outcome (OR= 4.7, 95% CI: 1.5-16, p amp;lt; 0.01). Conclusions: Having avoided illness during build-up and pre-race was positively associated with self-rated race performance outcome among recreational runners. Adjusting the desired performance outcomes with regard to recent illness and age may help recreational runners to more often achieve their goals and thereby prevent them from leaving the sport.

    Perceptions of Overuse Injury Among Swedish Ultramarathon and Marathon Runners: Cross-Sectional Study Based on the Illness Perception Questionnaire Revised (IPQ-R)2019Ingår i: Frontiers in Psychology, E-ISSN 1664-1078, Vol. 10, s. 1-11, artikel-id 2406Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Long-distance runners’ understandings of overuse injuries are not well known which decreases the possibilities for prevention. The common sense model (CSM) outlines that runners’ perceptions of a health problem can be described using the categories identity, consequence, timeline, personal control, and cause. The aim of this study was to use the CSM to investigate perceptions of overuse injury among long-distance runners with different exercise loads.

    Methods: The study used a cross-sectional design. An adapted version of the illness perception questionnaire revised (IPQ-R) derived from the CSM was used to investigate Swedish ultramarathon and marathon runners’ perceptions of overuse injuries. Cluster analysis was employed for categorizing runners into high and low exercise load categories. A Principal Component Analysis was thereafter used to group variables describing injury causes. Multiple logistic regression methods were finally applied using high exercise load as endpoint variable and CSM items representing perceptions of injury identity, consequence, timeline, personal control, and causes as explanatory variables.

    Results: Complete data sets were collected from 165/443 (37.2%) runners. The symptoms most commonly associated with overuse injury were pain (80.1% of the runners), stiff muscles (54.1%), and stiff joints (42.0%). Overuse injury was perceived to be characterized by the possibility of personal control (stated by 78.7% of the runners), treatability (70.4%), and that the injury context was comprehensible (69.3%). The main injury causes highlighted were runner biomechanics (stated by 78.3%), the runner’s personality (72.4%), and running surface biomechanics (70.0%). Among men, a belief in that personality contributes to overuse injury increased the likelihood of belonging to the high exercise load category [Odds ratio (OR) 2.10 (95% Confidence interval (95% CI) 1.38–3.19); P = 0.001], while beliefs in that running biomechanics [OR 0.56 (95% CI 0.37–0.85); P = 0.006) and mileage (OR 0.72 (95% CI 0.54–0.96); P = 0.026] causes injury decreased the likelihood. In women, a strong perception that overuse injuries can be controlled by medical interventions decreased the likelihood of high exercise load [OR 0.68 (95% CI 0.52–0.89); P = 0.005].

    Conclusion: This study indicates that recognition among long-distance runners of the association between own decisions in overuse injury causation is accentuated by increased exercise loads.

    Psychoform and somatoform dissociation among children and adolescents: An evaluation of a new short screening instrument for dissociation, DSQ-122019Ingår i: European Journal of Trauma & Dissociation, E-ISSN 2468-7499, Vol. 3, nr 4, s. 213-220Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction

    Today's assessment instruments for dissociation among adolescents are either relatively extensive or are specifically designed to identify either psychoform or somatoform dissociation.

    Objective

    A questionnaire that is shorter than any of the existing questionnaires and is concerned with both forms of dissociation would be helpful for both clinicians and researchers.

    Method

    Existing data from 462 adolescents who had answered Dis-Q Sweden and SDQ-20 were used to create a new questionnaire consisting of 12 items. A pilot study with 42 participants 15-19 years old, was carried out to test this new instrument, Dissociation Screening Questionnaire 12 (DSQ-12). DSQ-12 was then tested on 451 adolescents 10 to 20 years old. A matched clinical group of 25 adolescents in the same age range was used, in order to test the classification performance of DSQ-12.

    Results

    Results showed good reliability, convergent and construct validity was satisfactory, and dissociation differed between age groups as well as between genders.

    Conclusions

    Conclusions are that the developed DSQ-12 performed well psychometrically, was reliable and valid. DSQ-12 is easy to answer and is suitable for clinical screening purposes and future research.

    The diagnostic accuracies of the 2012 SLICC criteria and the proposed EULAR/ACR criteria for systemic lupus erythematosus classification are comparable2019Ingår i: Lupus, ISSN 0961-2033, E-ISSN 1477-0962, Vol. 28, nr 6, s. 778-782Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In a joint effort, the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR) recently proposed new criteria for the classification of systemic lupus erythematosus (SLE) with the overarching goal to identify potential participants for clinical studies. Herein, we present the first independent evaluation of these criteria in comparison with older classification grounds using an adult Scandinavian study population of confirmed SLE cases and individuals with SLE-mimicking conditions. We included 56 confirmed SLE cases meeting the 1982 ACR criteria (ACR-82) and/or the Fries diagnostic principle (antinuclear antibodies on at least one occasion plus involvement of at least two defined organ systems) and 55 controls with possible systemic autoimmune disease, including the presence of any SLE-related autoantibody. The proposed EULAR/ACR criteria showed a diagnostic sensitivity of 93% (95% confidence interval (CI), 0.83-0.98) compared with 83% (95% CI, 0.72-0.91) for the updated ACR criteria from 1997. The diagnostic accuracy of all tested classification grounds was fairly similar, achieving approximately 85%. However, the disease specificity of the EULAR/ACR criteria reached only 73% (95% CI, 0.59-0.83), which was comparable with the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria, 75% (95% CI, 0.61-0.85), but clearly lower than for ACR-82, 94% (95% CI, 0.83-0.99). In this first independent evaluation of a limited number of cases, we found comparable results with respect to diagnostic sensitivity, specificity and accuracy regarding the SLICC-12 and the proposed EULAR/ACR classification criteria. However, their specificity for SLE appeared to be lower compared with ACR-82.
