Abstract

Obesity is starting to become a health problem worldwide. Therefore, it must be addressed immediately. It is important to develop and evaluate interventions to reduce obesity prevalence by focus on behavioral therapy through health education. This study was aimed to determine differences in knowledge, intake patterns and BMI after giving health education for overweight and obese adolescent in Bulukumba District. This study was Quasi Experiment, which is pre-test and post-test with control group design. The groups in this study were divided into four; two treatment groups and two control groups. The first group was given health education through lectures with a booklet with WhatsApp application, the second group was given health education through lectures with booklets accompanied by text messages, the third group was given health education with lectures accompanied by leaflets and the fourth group was only given health education through media without lectures. The number of samples was 91 respondents. The results of Friedman's test analysis showed that there were differences in knowledge (p<0.001), differences in intake and BMI (p<0.001) in groups 1, 2 and 3, but no difference in intake patterns (energy p=0.008 and carbohydrates p=0.027) and BMI (p=0.140) in group 4. The use of booklets in the provision of health education for adolescents is added by re-education through the use of social media WhatsApp application to increase knowledge, changes in intake patterns and BMI in overweight and obese adolescents.
