Interaction of maternal age and mode of delivery in the development of postpartum depression in Yerevan, Armenia

Abstract

Background: To investigate determinants of development of postpartum depression among women in Yerevan, Armenia.

Method: A case-control study of all reproductive age (18-45) women having 1-3 months old children registered in 7 Primary Health Care (PHC) facilities, in Yerevan. We used Edinburgh Postnatal Depression Scale (EPDS) and a structured questionnaire to assess possible postpartum depression status of mothers and exposure status through telephone interviews.

Results: The study had a 96.7% response rate for 63 cases and 272 controls. The prevalence of possible postpartum depression was 14.4%. The risk of possible postpartum depression associated with age less than 25 years at childbirth was increased only among women who delivered their child through C-section (OR=7.8; 95% CI: 1.5-40.7). Meanwhile, this risk was much lower among women who delivered through vaginal delivery (OR=0.9; 95% CI: 0.4-1.8).

Limitations: EPDS had not been translated and validated in Armenia. Study population included only women having 1-3 months old children.

Conclusion: The study suggested that the effect of younger age at last childbirth on the risk of possible postpartum depression development was higher for women who gave birth through C-section compared to those with vaginal delivery. Despite the stressful and crisis conditions existing in Armenia over the past 2 decades the prevalence of possible postpartum depression does not differ much from that in other societies.
