Antenatal depression: Associations with birth and neonatal outcomes among women attending maternity care in Harare, Zimbabwe.

ABSTRACT

INTRODUCTION: Antenatal depression is highly prevalent and is associated with negative birth and neonatal outcomes. However, the mechanisms and causality behind these associations remain poorly understood as they are varied. Given the variability in whether associations are present, there is need to have context-specific data to understand the complex factors that go into these associations. This study aimed to assess the associations between antenatal depression and birth and neonatal outcomes among women attending maternity care in Harare, Zimbabwe. METHODS: We followed 354 pregnant women in second or third trimester, attending antenatal care services in two randomly selected clinics in Harare, Zimbabwe. Antenatal depression was assessed using the Structured Clinical Interview for DSM-IV. Birth outcomes included birth weight, gestational age at delivery, mode of delivery, Apgar score, and initiation of breastfeeding within one-hour postdelivery. Neonatal outcomes at six weeks postdelivery included infant's weight, height, illness, feeding methods and maternal postnatal depressive symptoms. The association between antenatal depression and categorical and continuous outcomes were assessed by logistic regression and point-biserial correlation coefficient, respectively. Multivariable logistic regression determined the confounding effects on statistically significant outcomes. RESULTS: Prevalence of antenatal depression was 23.7%. It was associated with low birthweight [AOR = 2.30 (95% CI 1.08-4.90)], exclusive breastfeeding [AOR = 0.42 (95%CI 0.25-0.73)] and postnatal depressive symptoms [AOR = 4.99 (95%CI 2.81-8.85)], but not with any other birth or neonatal outcomes measured. CONCLUSIONS: The prevalence of antenatal depression in this sample is high with significant associations demonstrated for birth weight, maternal postnatal depressive symptoms and infant feeding methods Effective management of antenatal depression is thus crucial to the promotion of maternal and child health.
