The relationship between postpartum depression and appropriate infant feeding practice in eastern zone of Tigray, Ethiopia: A comparative cross-sectional study.

Background: Understanding the relationship between postpartum depression and infant feeding practice may help to reduce the indirect impact of postpartum depression on infant feeding practice. This will further have a positive impact on reducing infant morbidity and mortality attributed to improper feeding practices. Although studies in the country have assessed the prevalence of infant feeding practices, those assessing the association between postpartum depression and infant feeding practices are lacking. Therefore, this study aimed to compare appropriate infant feeding practices and their associated factors among postpartum depressed and non-depressed mothers in Eastern Tigray.

Methods: A comparative cross-sectional study was conducted from March 2019 to April 2019. A multistage random sampling technique was used to select 171 mothers with postpartum depression and 342 mothers without postpartum depression. Data were collected using a structured questionnaire from the Monitoring and Evaluating for Breastfeeding Practices toolkit, then entered into Epi- info and exported into SPSS for further analysis. A binary logistic regression was applied to determine the association between postpartum depression and appropriate infant feeding practice.

Results: The overall prevalence of appropriate infant feeding practice was 37.6% (95% CI: 33.5%-41.9%). The prevalence was higher among mothers without postpartum depression 42.7% (95% CI: 42.9%-53.2%) than among postpartum depressed mothers 27.5% (95% CI: 24.7%-32.5%). The odds of appropriate infant feeding practice among mothers with infant birth orders of three or above was 58% (AOR = 0.42; 95% CI: 0.26-0.97) less than those mothers with infant birth orders of three and below. Households with monthly income 1000-1999 ETB (AOR = 2.26; 95% CI: 1.01-5.08), 2000-2999 ETB (AOR = 1.96; 95% CI: 1.21-4.73) and 3000-3999 ETB (AOR = 5.13; 95% CI: 1.97-13.4) were more likely to practice appropriate infant feeding.

Conclusion: The overall prevalence of appropriate infant feeding practices in the study area was low. A significantly higher proportion of mothers without postpartum depression practice appropriate infant feeding compared to mothers with postpartum depression. In addition, households with higher monthly incomes and mothers with infant birth orders three or above were significant determinants of appropriate infant feeding practice. Therefore, strengthening the provisions of nutritional education, integrating maternal mental health with routine maternal health care services, providing economic support to mothers with low income, and health education for multiparous women is a critical interventions to improve appropriate infant feeding practice.
