Antenatal depression: An examination of prevalence and its associated factors among pregnant women attending Harare polyclinics

Abstract

Background: Antenatal depression is the most prevalent common mental health disorder affecting pregnant women. Here, we report the prevalence of and associated factors for antenatal depression among pregnant women attending antenatal care services in Harare, Zimbabwe. Methods: From January-April 2018, 375 pregnant women, aged 16-46 years, residing mostly in Harare's high-density suburbs were recruited from two randomly-selected polyclinics. Antenatal depression was measured using the Structured Clinical Interview for DSM-IV. Sociodemographic data including; maternal age, education, marital status, economic status, obstetric history and experiences with violence were also collected. Chi-square tests and multivariate logistic regression analysis were used to determine the association between antenatal depression and participants' characteristics. Results: The prevalence of antenatal depression was 23.47% (95% CI: 19.27-28.09). Multivariate logistic regression analysis revealed intimate partner violence (IPV) [OR 2.45 (95% CI: 1.47-4.19)] and experiencing negative life events [OR 2.02 (95% CI: 1.19-3.42)] as risk factors for antenatal depression, with being married/cohabiting [OR 0.45 (95% CI: 0.25-0.80)] being a protective factor. Conclusion: The prevalence of antenatal depression is high with associated factors being interpersonal. Context-specific interventions are therefore needed to address the complexity of the factors associated with antenatal depression.
