Social well-being and problematic school absence among Danish adolescents: A nationwide cross-sectional study

Adolescents' well-being and school absence are important factors for public health. The aim of this study was to examine the association between social well-being and problematic school absence among Danish adolescents in the ninth grade, as well as to examine potential sex differences, using a large cohort of adolescents.

In this cross-sectional study, information on social well-being was obtained from the yearly Danish National Well-being Questionnaire mandatory in compulsory school. Data on school absence was obtained from the Ministry of Children and Education. The study population comprised 203,570 adolescents in the school years 2014/2015 to 2019/2020. The association between social well-being and problematic school-absence was analysed using logistic regression. A stratified analysis was made to investigate potential sex differences.

A total of 17,555 (9.16%) adolescents had problematic school absence, defined as >10% illegal absence and/or sickness absence in the ninth grade. Adolescents with low social well-being had higher odds for having problematic school absence compared with adolescents with high social well-being, adjusted odds ratio=2.22 (95% confidence interval 2.10-2.34). When stratifying for sex, the association was strongest for girls. The results remained after adjustment for parents' educational level and family structure.

Associations between adolescents' social well-being and problematic school absence were found, where girls had the strongest association. These findings might provide knowledge about social well-being as an important factor for problematic school absence, while underlining the importance of early focus and prevention, which is of importance for both the adolescents and society.
