This study will examine associations between neighborhood food environments, dietary intake and weight status among Latino families with preschool-age children. The specific aims of this work are to: (a) identify individual, familial and environmental predictors of perceived neighborhood food environments among Latino parents, (b) examine the association between parents’ neighborhood perceptions and children’s dietary intake and weight status, (c) evaluate food acquisition behaviors as a potential mediator of the relationship between perceived neighborhood food environments and children’s dietary intake; and (d) evaluate if perceived neighborhood food environments mediate and/or moderate effects of a family/school-based intervention on changes in dietary intake and weight status. The proposed study builds on a recently NIH-funded overweight prevention trial, the ‘Family Based Obesity Prevention in Latino Families’ study (FBOP), using baseline and post-intervention data from FBOP and adding measures of the perceived and objective food environments and activity space.
