Abstract
Few studies examined breastfeeding initiation and duration among mothers who were eligible for the Women Infants Children (WIC) program and did not participate. This study is sought to understand the role of WIC participation and poverty level in breastfeeding initiation and duration in South Carolina. The data came from the 2009–2010 South Carolina Pregnancy Risk Assessment Monitoring System (unweighted N = 1,796). All participants were classified as WIC participants, income-eligible non-WIC participants, and income-ineligible non-WIC participants. Logistic regression models were used to analyze the association between breastfeeding initiation and WIC participation. The Kaplan–Meier method and Cox proportional hazards models were used to determine whether the continuation of breastfeeding and hazards of discontinuing breastfeeding differed by WIC participation groups. In South Carolina, two out of three women (67.2 %) initiated breastfeeding. The breastfeeding initiation rate was higher among income-ineligible (84.0 %) and income-eligible (78.9 %) non-WIC participants than among WIC participants (55.5 %). Compared to WIC participants, both income-ineligible [odds ratio (OR) = 2.1, 95 % confidence interval (CI) 1.2–4.0] and income-eligible (OR = 2.6, 95 % CI 1.1–4.3) non-WIC participants were more likely to initiate breastfeeding. Among mothers who already initiated breastfeeding, after adjusting covariates, the hazard ratios for weaning within 34 weeks postpartum were not significantly different by WIC participation groups. This study confirmed WIC participants were less likely to initiate breastfeeding. Once initiated, WIC participation did not significantly impact breastfeeding duration in the early postpartum period. Poverty status may not play an important role in explaining disparities in breastfeeding initiation between WIC and non-WIC participants.
