Maternal Prenatal Mental Health Effects On Infant Emotional And Cognitive Development Trajectories

Abstract

Background: Maternal mental health during pregnancy is a major determinant of infant developmental outcomes. Psychological states such as stress, anxiety, and depression during pregnancy may influence fetal brain development through biological and behavioral pathways, which could have implications for children's emotional regulation, cognitive functioning, and developmental trajectories in early childhood. Objective: To examine the association between maternal mental health during pregnancy and trajectories of infant emotional and cognitive development.  Methodology: A quantitative cross-sectional study was conducted on 280 pairs of mother and infant. Data was collected by using maternal mental health assessment questionnaires, prenatal health records and standard infant emotional and cognitive developmental evaluation scales. Associations between maternal mental health and infant developmental outcomes were assessed using descriptive statistics, correlation analysis and multiple regression models. Findings: The results indicated that 31.8% of the mothers had moderate to high levels of prenatal psychological distress. Infants of mothers with positive prenatal mental health showed higher emotional development scores (Mean = 85.7, SD = 7.9) and cognitive development scores (Mean = 87.4, SD = 8.1) compared to infants exposed to elevated maternal distress (Mean = 72.3 and 74.1, respectively). Maternal prenatal mental health was positively correlated with emotional development (r = 0.63, p < 0.001) and cognitive development (r = 0.66, p < 0.001).  Conclusion: Prenatal maternal mental health has an important impact on infant emotional and cognitive development trajectories. Early detection and support for maternal mental health may improve child developmental outcomes and promote long-term emotional and cognitive well-being.
