Background: We aimed to evaluate the effect of school- based obesity prevention and management program applied to adolescents in a middle school on body mass index (BMI), weight-related attitude, eating behavior and physical activity of adolescents.
Methods: A total of 664 adolescents (14.7±0.9 years old) in a middle school located in Busan were study subjects. The obesity prevention and management program was conducted for 6 months, from March to September, 2005. Their weight and height were measured and their weight-related attitude, eating habit and physical activity were assessed using a questionnaire at baseline and after 6 months. Their weight status was classified into under-, normal-, and overweight according to their BMI at baseline.
Results: The prevalence of underweight and overweight was 6.2% and 19.3%, respectively. Among the adolescents with overweight, the BMI significantly decreased after 6 months compared to the BMI at baseline (P＜0.05), while the BMI was not significantly changed over 6 months among the under- and normal weight groups. The adolescents were more likely to become highly concerned about obesity-related problems (P=0.002) and actively participating in obesity prevention program (P=0.007) after 6 months compared to those attitude at baseline. The BMI significantly decreased in the adolescents whose eating behavior or physical activity were improved compared to their counterparts (P＜0.05).
Conclusion: The 6-months program for obesity prevention and management seemed to reduce BMI in overweight adolescents and raise concern about obesity related problems and promote participation in obesity prevention program in adolescents as a whole. Further long-term intervention studies need to be implemented. (J Korean Acad Fam Med 2008;29:585-594)
