Abstract

Objectives: Obesity is one of the most common metabolic and nutritional diseases in children of the 21st century. The objective of this study was to determine the effect of health education and physical activity demonstration on body mass index of 10-year old school children.

Methods: This is a randomized controlled study. Four schools in a district were randomly assigned into four groups: control (n=81), health education only (n=107), physical activity demonstration only (n=86) and both health education and physical activity demonstration (n=90). We included 10- year old pupils in the selected schools excluded those who had skeletal deformity and illiterate. All pupils were subjected to anthropometrics measurement and self-administered questionnaire of knowledge, attitude and practices on obesity, nutrition and physical activity at pre and nine weeks post intervention. Health education on obesity, dietary and physical activity were given through talks, mounting board, printed materials, handout, video and posters while physical activity demonstration were given via talk, video and actual exercise. Repeated measure analysis of variance was used for analysis.

Results: The prevalence of overweight / obesity of 10-year old ranged between 7.4-25.6%. There was a significant effect of intervention in the mean body mass index [6.123 (3, 360); p value<0.001].

Conclusion: Health education and physical activity demonstration were successful in reducing body mass index in 10-year old school children.
