Living with parents or with parents-in-law and postpartum depression: A preliminary investigation in China.

Background: Few studies have investigated the association between puerperal women's living situation and postpartum depression. The aim of this study was to examine the association between living with parents or with parents-in-law and postpartum depression among Chinese puerperal women.

Methods: A total of 1126 participants who completed questionnaire were included in our analysis. Postpartum depression status was assessed using the Edinburgh Postnatal Depression Scale. Logistic regression models were used to estimate the association between living with puerperal women's parents or with parents-in-law and risk of postpartum depression after adjustment for potential confounders.

Results: The prevalence of postpartum depression among participants was 11.8%. Of the 1126 participants, 524 (46.5%) lived only with their husbands, 387 (34.4%) lived with their parents-in-law, and 215 (19.1%) lived with their parents. Compared with those living only with their husbands, puerperal women living with their parents-in-law had higher risk of postpartum depression after adjustment for potential confounders (OR=2.48; 95% CI: 1.20, 5.15). No association between living with puerperal women's parents and postpartum depression was found after adjustment for confounders (OR=1.05; 95%CI: 0.42, 2.65).

Limitations: Although we adjusted for a wide range of potential confounders, we cannot rule out the possibility of residual confounding by other unmeasured factors, such as breastfeeding, intimate partner violence, and marital relationship.

Conclusions: Our findings suggest that living with parents-in-law may be a risk factor for postpartum depression among Chinese puerperal women. Future preventive interventions should include strategies that target the puerperal women who lived with parents-in-law.
