Limited access to affordable, healthy food and identifying as African-American or Hispanic-American are associated with greater risk of childhood obesity, especially for low-income individuals. To report on (1) the emergent theme of the influence of culture on primary caregivers' behaviors and motivations when preparing meals for their families; and (2) primary caregivers' perceptions of the nutritional information they receive from health care providers. Twelve focus groups with low-income, adult primary caregivers of children ages 3 to 6 years were conducted in Texas and the DC-Maryland-Virginia region and were segmented by race/ethnicity and access to grocery stores. Culture emerged as an important theme in influencing which foods participants cook at home. In some cases, that influence spilled over into the child's diet. In other instances, the food that participants reported making for their children varied from the food they make for themselves. Participants reported having high trust in health care providers, but acknowledged that health care providers' nutritional advice might not always be applicable. Our findings highlight the importance of considering the role culture might play in influencing and informing caregivers' decisions regarding children's diets, and also better understanding caregivers' perceptions of health care providers as a source of nutrition information for their children.
