RESUMO
OBJECTIVES: To determine why mothers in El Paso, Texas, choose to breast-feed but not exclusively and why breast-feeding duration is short. METHODS: This was a cross-sectional observational study of 300, mostly Mexican American, low-income mothers delivering at a county hospital who answered questions about breast-feeding and formula feeding, sociodemographics, and health habits. RESULTS: Most mothers (92.6%) in our study initiated breast-feeding, but only 20.3% breast-fed exclusively at the time of hospital discharge. Most mothers (73%) self-identified as Mexicans or Mexican Americans living on the border of the United States and Mexico. Mothers in our study chose to breast-feed if they decided to breast-feed during pregnancy, had breast-fed a previous child, had support from a female relative, and had attended college. Distinctively, most mothers in our study chose "las dos cosas" or to breast-feed and formula feed together early after birth. Acculturation failed to explain the breast-feeding decisions. CONCLUSIONS: Mexican American mothers who decided to breast-feed during pregnancy, breast-fed another child, attended college, and enlist a female relative's breast-feeding help were more likely to choose breast-feeding exclusively. Most Mexican American low-income mothers in our study chose "las dos cosas."
