Postnatal depression (PND) has been a common depressive mental disorder among the mothers in a low-income country like Bangladesh where stunting, underweight and wasting are prevalent among infants. The present prospective cohort study was carried out among 297 non-depressed and 103 depressed mothers (ages 18-36 years) to find the association between post natal depression and growth of infants. Data were collected by face to face interview through semi-structured questionnaires and anthropometric measurements were taken with proper anthropometric techniques and calibrated instruments. Postnatal depression was assessed by the Edinburgh Postnatal Depression Scale and infants' physical growth was assessed by Z score of weight, length and Mid-Upper Arm Circumference (MUAC). The overall prevalence of post natal depression was found 22% [95% CI, 21.71-30.29]. Infants of depressed mothers were found iller in comparison with the infants of non-depressed mothers (p < 0.001) which could result in growth retardation of infants. According to the MUAC level, infants of depressed mothers were more at risk of malnutrition (p < 0.001). Early detection of postpartum depression, implementation of interventions, prevention or treatment of maternal depressive disorders and effective strategies will not only ameliorate the impact of PND among mothers but also facilitates infant growth.
