Ofosu NN, et al. - Researchers assessed the impacts of APPLE Schools [a Comprehensive School Health (CSH) project, started in schools in socioeconomically disadvantaged areas where dietary habits are poor, physical activity (PA) levels are low, and obesity rates are high] on health-related knowledge, attitudes, self-efficacy, diet, PA, and weight status, seven years after the start of the project, when students were in junior high and high school, presuming that APPLE School graduates and comparison school graduates will remain at similar levels for these indicators. The effects of APPLE Schools could continue into adolescence or the new school environment could have an equalizing effect on the students as no difference was found between the APPLE School graduates and comparison school graduates. Extending CSH initiatives into junior high/high schools was recommended as lifestyle practices are adopted throughout childhood and adolescence, and the school environment has an important influence on development.
