Human breast milk provides significant health benefits, yet breastfeeding rates in the United States remain suboptimal. Although Hispanic women generally have higher breastfeeding rates, increasing acculturation may negatively influence breastfeeding behavior. Using data from the 2000–2001 Oregon Pregnancy Risk Assessment Monitoring System (PRAMS), this study examined the association between acculturation and any breastfeeding at ten weeks postpartum among Hispanic women. Acculturation was measured by maternal nativity and survey language. Highly acculturated women were significantly less likely to breastfeed at ten weeks than women with low acculturation, even after adjustment for covariates. Acculturation remained the strongest predictor of breastfeeding, highlighting the need for culturally tailored breastfeeding promotion efforts.
