Impact of breastfeeding self-efficacy and sociocultural factors on early breastfeeding in an urban, predominantly Dominican community.

Abstract

Latinas have high breastfeeding initiation rates that decrease significantly in the first postpartum months. Little is known about the effects of self-efficacy and sociocultural factors on early breastfeeding among low-income Latinas. This study quantifies early breastfeeding rates and identifies factors associated with breastfeeding at 4-6 weeks postpartum in our community. Mothers were recruited from a newborn clinic (NBC) in the first postpartum week. Questionnaires in the NBC and 4-6 weeks later assessed feeding practices, breastfeeding self-efficacy, and sociocultural factors. Feeding practices in the well baby nursery (WBN) were obtained by chart review. A scale from "1" (exclusive formula feeding) to "5" (exclusive breastfeeding) characterized feeding practices. Paired-sample t tests assessed change in feeding practices, and regression analysis assessed the impact of factors on breastfeeding at 4-6 weeks. We interviewed 209 women: 86.1% Latina, 47.3% foreign-born, and 94.2% Medicaid-recipients. Breastfeeding increased from WBN to NBC (2.6±1.2 to 2.9±1.4; p<0.05) and then decreased by 4-6 weeks (2.9±1.4 to 2.5±1.44; p<0.05), without significant change between WBN and 4-6 weeks. Higher levels of education [β=0.21 (0.08, 0.56)], breastfeeding a previous child for ≥6 months [β=0.35 (0.57, 1.8)], foreign birth [β=0.2 (0.06, 1.07)], and higher breastfeeding self-efficacy scores [β=0.38 (0.02, 0.05)] were associated with more breastfeeding. Higher breastfeeding self-efficacy scores were associated with exclusive breastfeeding [adjusted odds ratio=1.18 (1.05, 1.32)]. Breastfeeding self-efficacy was the sole, modifiable factor associated with exclusive breastfeeding. Efforts to improve breastfeeding self-efficacy may serve to support breastfeeding in this population.
