Husband-wife Relationship, Neonatal Health, Breast Milk Volume and Postpartum Depression: A Prospective Cohort Study

Postpartum depression (PPD) is a major public health problem that has negative effects on mothers, infants, and society. This study was aimed at investigating the prevalence of PPD and elucidating the delivery factors implicated in PPD so as take more targeted measures for reducing the potential risk factors. A prospective cohort study was conducted. Following the criterion, 151 pregnant women were included in the study. The Edinburgh Postpartum Depression Scale (EPDS) and the general questionnaire were filled out 2-3 days after delivery. At weeks 2 and 6 postpartum, the EPDS was reassessed either online or via telephone. Also, electronic medical records based on relevant information during the delivery period were collected. Statistical significance was defined as p < 0.05. A high rate of PPD (31.13%) was reported. Univariate correlation analysis showed statistically significant differences in the husband-wife relationship (χ² = 18.497, p < 0.001), neonatal health (χ² = 14.710, p < 0.001), and breast milk volume (χ² = 5.712, p = 0.017) between PPD and normal control groups. Adjusting for other covariates, multivariate logistic regression analysis showed that satisfactory conjugal relation could reduce the risk of PPD (OR, 0.053; p = 0.022); Neonatal health problems significantly increase the risk of PPD (OR, 6.497; p = 0.001); Adequate breast milk could alleviate the risk of PPD (OR, 0.351; P = 0.045). Data analysis suggests that marital discord and unhealthy new-born are independent risk factors; nevertheless, sufficient breast milk is a protective factor against PPD. Healthcare workers such as hospital and community doctors and social workers should pay attention to PPD. Furthermore, perinatal emotional support, health education, and EPDS assessment need to be incorporated into maternity care. Screening and personalized psychological counselling should be carried out for high-risk pregnant women with PPD.
