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 and underscores the need for future interventions targeted at increasing the number of support providers to prevent antepartum depression. social support, antepartum depression, marginal structural models, prenatal interventions © The Author(s) 2018.
