    The intervention program-the School Nutrition Policy Initiative-included teacher training, nutrition education for students, a school nutrition policy, social marketing, and communication and collaboration with parents. The program incorporated healthy eating throughout the school day, thus changing the whole school environment. For example, soda was replaced with water, 100% fruitjuice, and low-fat milk; candy was eliminated completely; and only healthy snacks were provided. Students were also encouraged to be more physically active and were rewarded for making healthful decisions.

    The study results show that a school-based intervention can help reduce the development of overweight among children. However, the fact that 7.5 percent of students in the intervention schools still gained weight over the course of two years suggests that more aggressive prevention programs may be necessary and that they should be implemented earlier than the fourth grade.
