Parental mental disorders and school performance among non-immigrant and second-generation immigrant children in Sweden

Introduction: Immigrant children are often challenged at school. School performance is an important predictor of future socioeconomic position and mental and physical health. While studies have investigated parental mental disorders as a potential factor for poor school performance, no studies have investigated this among children with foreign-born parents, i.e., second-generation immigrant children. We aimed to examine whether parental depressive, anxiety, and personality disorders, affect school performance among non-immigrant children and second-generation immigrant children in Sweden. Methods: Multiple nationwide population register data in Sweden were used. Non-immigrant children, i.e., children born to two Swedish-born parents (n = 593,515), and second-generation immigrant children with two foreign-born parents from non-Western regions (n = 71,721) were included. School grades in the final compulsory school year were used as outcome. Parental mental disorders were measured in the inpatient and outpatient registers. While adjusting for potential confounders, the association between parental mental disorders and school grades was assessed by a linear mixed model. Interaction terms were included to examine whether the association between parental mental disorders and school grades differed by children's immigration status. Results: Parental mental disorder was associated with lower school grades for both non-immigrant and secondgeneration immigrant children and in both males and females. The school grades were lower among secondgeneration immigrant children but the effect of parental mental disorder was smaller among secondgeneration immigrant children than among non-immigrant children. Conclusion: Parental mental disorders affected the school performance of all children negatively. Future studies could examine what type of support at school for both second-generation immigrant children and non-immigrant children of parents with mental disorders are most beneficial.
