This study will examine the food environments among YMCA after-school programs that primarily serve African-American children on Chicago’s South side, as well as factors impacting the implementation of such after-school programs and snack offerings within these programs. Specifically, the aims of this work are to use qualitative and quantitative methods to: (a) identify the potential organizational, environmental, and individual factors contributing to and/or hindering implementation of the YMCA Activate America initiative and its modification of the after-school program food environment, (b) identify factors influencing the provision of healthy snacks in these programs, (c) obtain a better understanding of the after-school program food environment during snack time, and (d) obtain a better understanding of current dietary patterns among children attending these programs.
