Association between family members and risk of postpartum depression in Japan: Does “who they live with” matter? -The Japan environment and Children's study

We found that “who a pregnant woman lives with” affects the risk of PPD in the first month postpartum, and high levels of perceived partner's involvement in childcare reduced harmful effects/increased protective effect of family members on PPD incidence. These findings suggested that interventions to increase perceived partner's support for childcare may be effective in preventing PPD, regardless of living situation.
