Selling sex is not uncommon among adolescents and we need to increase our knowledge of how this affects them. The aim of this study was to investigate adolescents who sell sex regarding sexual, mental and physical abuse, mental health as estimated by using the Hopkins Symptom Check List-25 (HSCL-25), self-harm behaviour and the adolescents' experience of receiving help and support. The study was carried out on a national representative sample of adolescents (mean age 18.3 years) in Swedish high schools in the final year of their 3-year programme. The study had 3498 participants and a response rate of 60.4%. Of the adolescents, 1.5% stated that they had sold sexual services. The selling of sex was associated with a history of sexual, mental and physical abuse. Poorer mental health and a higher degree of self-harm behaviour were reported among the adolescents who had sold sex. Help and support was sought to a greater extent by adolescents who had sold sex but these adolescents were not as satisfied with this help and support as the other adolescents. Adolescents that sell sex are a group especially exposed to sexual, mental and physical abuse. They have poorer metnal health and engage in more self-harm behaviour than other adolescents. They are in need of more help and support than other adolescents ant it is reasonable to assert that more resources, research and attention should be directed to this group to provide better help and support in the future.

In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.

Sex as self-injury has become a concept in Swedish society; however it is a largely unexplored area of research, not yet conceptualized and far from accepted in the research field. The use of sex as a way of affect regulation is known in the literature and has, in interviews with young women who sell sex, been compared to direct self-injury, such as cutting or burning the skin. The aim of this study was to investigate the self-reported frequency of sex as self-injury and the association to sociodemographic factors, sexual orientation, voluntary sexual experiences, sexual risk-taking behaviors, sexual, physical and mental abuse, trauma symptoms, healthcare for psychiatric disorders and non-suicidal self-injury.
