Abstract
We used marginal structural models to evaluate associations of social support with antepartum depression in late pregnancy, had everyone had high social support both pre-pregnancy and during early pregnancy, as compared to having low social support at one of the two-time points or low social support at both time points. In 2012-2014, pregnant Peruvian women (N = 3,336) were recruited into a prospective cohort study (mean gestational age: 9 weeks). A follow-up interview (N = 2,279) was conducted (26-28 weeks of gestation). Number of available support providers and satisfaction with social support were measured using Sarason Social Support Questionnaire-6. Depression was measured using Edinburgh Postnatal Depression Scale. Low number of support providers (Odds Ratio = 1.62, 95% Confidence Interval:1.12-2.34) at both time points was associated with increased risk of depression. The association for low satisfaction at both time points was marginally significant (Odds Ratio = 1.41, 95% Confidence Interval: 0.99-1.99). Depression risk was not significantly increased for women who reported high social support at one of the two-time points. Our study reinforces the importance of assessing social support before and during pregnancy ...
