As more U.S. children grow up in Latino families, understanding how social class, culture, and environment influence feeding practices is key to preventing obesity. The authors conducted six focus groups and 20 in-depth interviews among immigrant, low-income Latina mothers in the Northeast United States and classified 17 emergent themes from content analysis according to ecologic frameworks for behavior change. Respondents related environmental influences to child feeding, diet, and activity, namely, supermarket proximity, food cost, access to recreational facilities, neighborhood safety, and weather. Television watching was seen as integral to family life, including watching during meals and using TV as babysitter and tool to learn English. Participation in the WIC program helped families address food insecurity, and child care provided healthy eating and physical activity opportunities. Health promotion efforts addressing obesity trends in Latino children must account for organizational and environmental influences on the day-to-day social context of young immigrant families.
