US secondary schools and food outlets

We examined the availability of fast food restaurants and convenience stores within walking distance (0.5 miles or 805 m) of US public secondary schools. We found that one-third of schools nationwide have at least one fast food restaurant or convenience store within walking distance. In multivariate analyses, schools in the lowest-income versus the highest-income neighborhoods have more fast food restaurants and convenience stores, while schools in African-American versus White neighborhoods generally have fewer food outlets. Furthermore, urban neighborhoods with a high school versus no secondary school have more food outlets. Curbing the obesity epidemic among adolescents requires addressing the food environment surrounding schools.
