OBJECTIVE: To examine the association between the maternal Stress to Resiliency Ratio (SRR) and postpartum depression (PPD).

METHODS: We used data from the Los Angeles Mommy and Baby (LAMB) study, a mailed survey based on a multistage clustered design with telephone follow-up for non-respondents. Analyses were based on the responses of 706 women who had a live birth in LA County in 2007. The maternal resiliency index comprised personal resources (self-esteem and mastery) and social resources (partner, social network, and neighborhood support) that women drew upon during pregnancy. The stress index consisted of severe life events and perceived stress during pregnancy. The stress index was divided by the resiliency index to create the raw SRR, which was then transformed into a natural log SRR. An SRR>0 signified greater stress relative to resiliency. PPD was measured using a 9-item Center for Epidemiological Studies Depression Scale (range of 0-27). Logistic regression analyses were used to assess the association between the SRR and PPD.

RESULTS: 38.2% of respondents were categorized as suffering PPD (cutoff point=7). The maternal SRR was significantly associated with having PPD (AOR=25.3, 95% CI=11.9, 53.5), even after controlling for prenatal depression, sociodemographic factors, parity, pregnancy complications, and having a low birthweight or preterm baby.

CONCLUSIONS: Experiencing greater stress than resiliency during pregnancy is significantly associated with the risk of PPD. Interventions during the preconception and prenatal periods are warranted to increase resiliency among high-stress women in order to improve postpartum mental health and long-term maternal and child health outcomes.
