Objectives This longitudinal population study aimed to investigate if maternal depression at different time points during the perinatal period impacts children's social-emotional development at 2 years of age. Methods Participants were women (n = 1235) who gave birth at Akershus University Hospital in Norway. Maternal depressive symptoms were assessed by using the Edinburgh Postnatal Depression Scale at pregnancy week 32 and at 8 weeks and 2 years postpartum, whereas children's social-emotional development at the age of 2 years was assessed by using the Ages and Stages Questionnaire: Social-Emotional. Bi- and multivariate logistic regression analyses were conducted to examine the linkage between maternal perinatal depression and children's early social-emotional development. Results Multivariate analyses showed that social-emotional problems in the child 2 years after birth were strongly associated with maternal depression at pregnancy week 32 (adjusted odds ratio (aOR) 3.4; 95 % CI 1.4-8.0), depression at 8 weeks postpartum (aOR 3.8; 95 % CI 1.7-8.6), and with depression at both time points (aOR 3.7; 95 % CI 1.5-10.1). Conclusion Findings indicate pre- and postnatal depression each bears an independent, adverse impact on children's social-emotional development.
