The aim was to test the hypothesis that parental alcohol problems and low socioeconomic position would be associated with higher odds ratio of emotional symptoms and depression as compared to high socioeconomic position and parental alcohol problems. Data came from Danish National Youth Study 2014, a web-based national survey with 75,853 high school and vocational school students participating, merged with register-data on family socioeconomic position. Multi-level logistic regression models (nesting participants within schools) were used to assess the association between perceived parental alcohol problems and frequent emotional symptoms and depression and effect modification by financial strains in the family, family income, or parental educational level. All analyses were adjusted for age, sex, education, immigration status, and cohabitation with parents. Young people with parental alcohol problems had higher odds ratio of experiencing frequent emotional symptoms (OR = 1.56 [1.46-1.66]) and depression (OR = 2.07 [1.88-2.28]), compared to young people without parental alcohol problems. There was no effect modification between severity of parental alcohol problems and the measures of socioeconomic position on the odds ratio of frequent emotional symptoms and depression. This study found that young people with parental alcohol problems in all social strata had higher odds ratios of frequent emotional symptoms and depression compared to young people without parental alcohol problems; the more severely they had been affected by parent's alcohol problems, the higher the odds ratios of frequent emotional symptoms and depression.
