Commentary: Promoting positive mental health during pregnancy-reflections on Lahdepuro et al. (2022)

Lahdepuro et al. performed a sound large-scale prospective pregnancy cohort study showing an association between positive maternal prenatal mental health and a reduced risk of developing clinically diagnosed childhood mental and behavioral disorders. Beneficial effects were also observed among the offspring of mothers experiencing mental health problems before and during pregnancy. The pathbreaking findings of Lahdepuro et al. set the stage for future research to shed more light on the so far almost unknown (neuro)biological mechanisms underlying the link between positive maternal prenatal mental health and child outcomes. More knowledge is needed about prenatal psychological and social factors enacting the potential of positive mental health as a resilience source buffering against maternal prenatal mental health problems and by this protecting subsequent child development. This also calls for further development, optimization, and evaluation of positive mental health-enhancing interventions during pregnancy, especially for future mothers having mental health problems.
