Randomized Controlled Trial Multicenter Study
Effects of changes in lunch-time competitive foods, nutrition practices, and nutrition policies on low-income middle-school children's diets.
The School Nutrition Advances Kids project tested the effectiveness of school-initiated and state-recommended school nutrition practice and policy changes on student dietary intake in low-income middle schools. ⋯ New USDA nutrition standards for à la carte and vending will likely increase the healthfulness of middle school children's diets.

Randomized Controlled Trial
The impact of a 3-year after-school obesity prevention program in elementary school children.
Children tend to be sedentary during the after-school hours, and this has deleterious effects on their health. The objective of the present study was to determine the effects of a 3-year after-school physical activity (PA) program, without restriction of dietary energy intake, on percent body fat (%BF), cardiorespiratory fitness (CRF), and cardiometabolic markers in children. ⋯ An after-school PA program was effective in reducing adiposity and improving CRF, especially in the children who attended the sessions at least 3 days/week. However, the favorable effects on %BF and CRF were lost over the summer. Thus, it is critical to incorporate strategies that attract and retain the children to receive an adequate dose of PA year-round.
