Maternal mental health plays a crucial role in determining both pregnancy and child development outcomes. Mental health disorders, including depression, anxiety, and stress, are common during pregnancy and can significantly affect maternal well-being, labour complications, and neonatal health. Untreated mental health conditions during pregnancy increase the risk of preterm birth, low birth weight, and developmental delays in infants. Additionally, maternal mental health issues can hinder bonding, affect postpartum recovery, and influence the long-term emotional and cognitive development of children. Effective screening and early intervention are essential for improving both immediate and long-term health outcomes for mothers and their children. Tools such as the Edinburgh Postnatal Depression Scale (EPDS) and Generalized Anxiety Disorder-7 (GAD-7) are commonly used to identify mental health concerns during pregnancy, yet challenges such as underreporting, stigma, and cultural barriers remain. Psychosocial interventions like cognitive-behavioural therapy (CBT), peer support, and pharmacological treatments can offer relief to mothers, but these must be carefully tailored to the needs of the pregnant population. Furthermore, integrated care approaches involving obstetricians, mental health professionals, and paediatricians are essential for providing comprehensive support. Policy reforms to improve healthcare access, reduce stigma, and offer workplace flexibility can also help mitigate maternal mental health challenges. Addressing maternal mental health not only improves the health of mothers but also promotes healthier, more resilient future generations.
