Association between maternal history of mental illness and neurodevelopment of children during the first 3 years: The Japan Environment and Children's Study.

Aim: The impact of maternal mental illness on children's neurodevelopment has been insufficiently investigated, particularly in large populations. In this study, we examined the association between maternal mental health history and child neurodevelopment during the first 3 years postpartum, using large-scale data from the Japan Environment and Children's Study (JECS).

Methods: We analyzed data from 64,389 mother-offspring pairs enrolled in JECS.
