Kinge JM, Øverland S, Flatø M, et al. - In this registry-based study, experts aspired to explore whether parental income was correlated with childhood diagnoses of mental disorders identified through national registries from primary healthcare, hospitalizations and specialist outpatient services. The study included 1,354,393 children aged 5–17 years, comprising 7,261,964 person-years from 2008 to 2016. Except for eating disorders in girls, there were significant differences in mental disorders based on parental income. Mental disorders were 3 to 4 times more common in children with parents in the lowest vs highest income percentiles. These associations were not fully explained by parents' own mental disorders, other socio-demographic factors, or genetic confounding.
