Asking about alcohol consumption during pregnancy: how prevalence rate is affected by the formulation of the question
(English)Manuscript (preprint) (Other academic)
Studies of alcohol consumption during pregnancy in Sweden have reported prevalence rates from 6% to 30%. The reason for these differences is unknown. The aim of this study was to compare how alcohol consumption is reported by pregnant women when asked explicitly to report drinking after pregnancy recognition compared with asking about drinking during pregnancy without stating if the time before pregnancy recognition should be included. Data were collected from two groups of women. The women in group A were asked to estimate their alcohol consumption during pregnancy and the women in group B were asked to estimate their alcohol consumption during pregnancy, after pregnancy recognition. There was a significant difference in the reported prevalence rate between the cohorts: 9.3% in cohort A (n=1041) and 6.8% in cohort B (n=933). The results from this study may explain some of the variations in previously reported prevalence rates. To be able to compare different studies, it is important to be clear about the methodological aspects.
