Reducing overweight through a multidisciplinary school-based intervention.
OBJECTIVE
This study sought to evaluate the effectiveness of a multidisciplinary elementary school-based intervention entitled Wellness, Academics & You. The primary areas of impact examined were BMI, consumption of fruits and vegetables, and physical activity.


METHODS
The sample consisted of 1013 students in fourth and fifth grades from 69 classes in four states. Intervention and comparison classes were randomly selected at each school. Intervention teachers participated in workshops on the intervention and received program materials. BMI was calculated for baseline and post-data points based on measured height and weight collected by trained research teams. Baseline surveys were administered by the students' teacher in the presence of one of the research team members and collected.


RESULTS
SPSS (SPSS, Inc., Chicago, IL) analysis of post-data shows significant positive shifts (p = 0.01) in BMI in the intervention group compared with the comparison group. Notable increases in the consumption of fruits and vegetables and increased physical activity levels were reported in the intervention group.


CONCLUSIONS
Data from this study indicate that this school-based program may contribute to the reduction of overweight and obesity. The intervention was well received by the classroom teachers and shows promise for a school-based obesity prevention initiative. This program has shown the capacity to effect positive changes in BMI through consumption of fruits and vegetables and physical activity. The evaluation covered a limited time period and, therefore, warrants additional studies to determine whether long-term program fidelity will result in continued improvement.
