Middle school health study

Intervention helps at-risk middle-school students stay healthy
Middle-school students are healthier when schools intervene in their exercising and eating, according to results of a recent study. Intervention methods used over a three-year period were found to reduce obesity rates among minority and low-income middle-school students, who are often at risk for long-term health problems.
