RESUMEN
Aims: We aimed to investigate associations between mental health and sociodemographic characteristics among schoolchildren in Denmark. Methods: We performed a cross-sectional survey from January to October 2019 among 4th to 9th graders (N=1247) based on pilot data from a nationwide research project Stress-free Everyday LiFe for Children and Adolescents REsearch (SELFCARE). We assessed mental health using the five-item World Health Organization Well-Being Index and the self-report version of the Strengths and Difficulties Questionnaire. We investigated associations between mental health and sex, age in terms of grade, type of school, family setting and geographic region using regression analysis. Results: Mental health was poorer among girls in the older classes compared to girls in 4th grade, and better among boys in the older classes compared to boys in 4th grade. We found no difference in mental health among schoolchildren in municipal and private schools. Mental health was poorer among both girls and boys living alternately with their parents compared to residing with both of them. Mental health varied across geographic regions. Conclusions: We found associations between mental health and sex, age in terms of grade, family setting and geographic region.
