Maternal postnatal depressive symptoms and early achievement of developmental milestones in infants and young children: A meta-analysis

Abstract

Screening for social determinants of health, including maternal depression, is a recommended pediatric practice. However, the magnitude of association between maternal and child screening tools remains to be determined. The current study evaluated the association between maternal postnatal depressive symptoms and child developmental milestones, as well as moderators of these associations. A comprehensive search strategy was carried out in four databases (MEDLINE, EMBASE, APA PsycINFO, and Cochrane Central Register of Controlled Trials) from database inception to September 2022. Studies that examine postnatal depressive symptoms and associations with infant and early child (<6 years) achievement of developmental milestones were included. Data were extracted by two independent coders and a random-effects meta-analysis was used to estimate pooled effect sizes and test for moderators. A total of 38 non-overlapping studies (95,897 participants), all focused on maternal postnatal depression, met inclusion criteria. The pooled effect size for the association between postnatal depressive symptoms and early achievement of infant and child developmental milestones (N = 38; r = −.12; 95% CI = −.18, −.06) was small in magnitude. Child age at maternal depression measurement was a moderator, whereby effect sizes became greater for older children. Despite small effects, maternal postnatal depressive symptoms should be included in screening during routine well-child visits to enhance child development outcomes.
