The Effectiveness of the Health Promoting School Intervention Model in Reducing Overweight and Obesity Among School Children in Indonesia: a Mixed-Methods Protocol Study

Summary

The prevalence of obesity in children is increasing rapidly, Among children aged 5-12 years, 18.8% have severe overweight, comprising 10.8% who are obese and 8.8% who are over. The development of effective and sustainable intervention strategies to prevent childhood obesity in Indonesia is becoming increasingly important, particularly given the limited implementation of health-promoting schools in the country.

The first Phase using qualitative exploration was a needs assessment will be using of social cognitive theory. The second Phase will be the development model intervention modification of the health promotion school WHO and "Health School". The third Phase is the quantitative stage using a Cluster Randomised Controlled Trial to analyse differences and test the effectiveness of the HPS model. This study will be conducted in 8 primary schools located in Makassar, South Sulawesi. School in Makassar city and schools from outside Makassar city, randomly selected for the trial. Then the selected schools are randomly divided into school for nutrition education and physical activity. Intervention, while school each for comprehensive intervention. The study will be target students in Grades 4 and 5 of primary school. Assessments for the primary objective (BMI Z score), and secondary objectives (change in knowledge, self-efficacy, and health literacy) in thirds study arm. The subsequent phase will assess the efficacy of the intervention in terms of reductions in BMI Z scores, improvements in knowledge, self-efficacy and health literacy. Concurrently, the exploration of parental and teacher knowledge and insights regarding health promotion in schools and its potential in reducing overweight and obesity in children will be conducted.

Nutrition education, physical activity intervention, and health promoting school model trials

A nutrition education and physical activity intervention, combining a pilot health promoting school model that includes health education and recreational enhancement with the curriculum of a government-designated healthy school, was designed to reduce childhood overweight and obesity. The programme was implemented over 6 months. This program has been widely conducted in several countries, but there are still many differences from previous studies, especially in terms of strengthening qualitative studies in the first stage, then in the intervention stage using a Cluster Randomised Controlled Trial design. Another advantage of this study is the combination of intervention and health promoting school. In Indonesia, there are few intervention studies in reducing overweight and obesity in children, some only focus on descriptive studies such as nutritional knowledge, physical activity measures using questionnaires to determine the relationship or measure BMI.
