Objective: Previous research suggests that children of parents with depressive symptoms have impaired mental health. However, most of the research has focused on postpartum depression in mothers. The purpose of the present review was therefore to compile data on the mental health of children over two years old whose parents have depressive symptoms in the Nordic countries, to provide a clear picture of the current state of research. Method: Systematic literature searches were conducted in the databases PubMed and PsycInfo. After a relevance review, eleven articles remained which were included in the overview. Due to the heterogeneous data of the studies, the results were compiled through narrative synthesis. Results: Positive associations were found between parents' depressive symptoms and various forms of mental health problems in children in many of the studies, while several of them could not confirm a connection. Fathers' depressive symptoms did not appear to correlate as strongly with the children's well-being as mothers' symptoms did. The results indicate that boys' problems manifest more as externalizing problems compared to girls, while internalizing problems appear to occur to a similar extent in both genders. No clear pattern could be seen regarding the children's age. Conclusion: The results suggest that children of parents with depressive symptoms are at risk for impaired mental health, which should be taken into consideration in areas such as healthcare and social services. More research is needed, for example, regarding causal relationships and effect sizes.
