[Associations between Maternal Postpartum Depression and Psychosocial Factors Including Marital Relationship and Social Support].

ABSTRACT

OBJECTIVES: We aimed to investigate the psychosocial factors for postpartum depression as indicated by a high score of the Edinburgh Postnatal Depression Scale (EPDS), including marital relationship and social support. Relevant factors for antenatal depression were also analyzed. METHODS: Thirty-five wife-and-husband pairs who visited University Hospital A for the wife's antenatal health check-up participated in a questionnaire survey using the Japanese version of the EPDS. Social support from the wife's husband, kins, and others including friends at the third trimester of pregnancy and 1 month after birth was assessed. The Marital Love Scale (MLS) was also used, and two marital relationship questions were asked regarding the husband's and wife's considerate actions toward each other during pregnancy. Binary logistic regression analysis was conducted to determine adjusted associations between higher EPDS scores (≥5 for postpartum depression and ≥7 for antenatal depression) and indicators for social support and marital relationships. RESULTS: The most relevant factor for higher postpartum EPDS scores was a higher antenatal EPDS score, followed by the couple's poor communication skills (the wife did not feel any appreciation from her husband) during pregnancy and no support from the wife's husband during the postpartum period. The wife's poor marital communication skills and the husband's low MLS scores during pregnancy were associated (borderline significance) with the wife's higher antenatal EPDS scores. CONCLUSIONS: A good marital relationship before birth and support by the husband after birth may be important for preventing postpartum depression.
