The Hispanic Paradox: Socioeconomic Factors and Race/Ethnicity in Breastfeeding Outcomes

Le résumé fourni par la source

BACKGROUND: Breastfeeding has multiple benefits for both mother and infant. Previous studies have shown that Hispanic/Latina women have higher rates of breastfeeding and better health outcomes than non-Hispanic black (NHB) women of similar socioeconomic status. Our primary objective was to explore the association of race/ethnicity with breastfeeding rates and the impact of socioeconomic factors on initiation and continuation of breastfeeding. MATERIALS AND METHODS: We performed a hypothesis-generating secondary analysis of a prospective cohort study of perinatal mental health in a diverse sample of 213 mothers. Twenty-eight participants self-identified as non-Hispanic white, 43 as NHB, and 142 as Hispanic/Latina. We examined bivariate relationships and performed logistic regression analysis for a series of maternal, infant, and psychosocial factors to examine their individual effect on the breastfeeding and race/ethnicity relationship odds ratio (OR). RESULTS: Hispanic/Latina women were more likely to initiate exclusive breastfeeding at delivery compared with NHB women (OR 2.4, 95% confidence interval: 1.2-4.9, p = 0.01). Adjustment for maternal, infant, and psychosocial factors measured did not statistically significantly attenuate the OR for initiation of breastfeeding between NHB and Hispanic/Latina women. Women with a history of sexual abuse were also more likely to initiate exclusive breastfeeding (67%) compared with women without a sexual abuse history (54%, p < 0.05). CONCLUSIONS: In this low socioeconomic status cohort study, Hispanic/Latina women had higher proportions of any amount of breastfeeding compared with their NHB counterparts. This difference was not attenuated by any of the maternal, infant, or psychosocial factors examined, although our secondary analysis of this prospective cohort was limited by the available covariates in the parent study.
