Digital Intervention to Improve Physical Activity Behaviour In Overweight and Obese Adolescents

This is a study protocol to test the feasibility of a digital intervention aiming to increase physical activity in overweight and obese adolescents. This study will be conducted in the state of Selangor, Malaysia. The intervention will be provided in two public schools. Another two public schools, which will be matched on the basis of similar socioeconomic background of attending students and curriculum structure, will act as control group. Additional schools may be recruited to fulfil required sample size. A digital behaviour change intervention (FIT-TEENS) will be delivered to overweight and obese adolescents (aged 13-18 years) using an online learning platform (EdApp) over 10 weeks to provide information on physical activity and the behaviour change aspects towards physical activity. The participants who received the intervention will be compared with the control group, where no intervention will be delivered, who will be requested to continue their usual physical activities. To determine the feasibility of the intervention, the researchers will obtain views and overall satisfaction from participants on the intervention and trial, and determine the proportion of participants who completed all intervention modules and outcome measures. In addition to feasibility measures, participants' physical activity behaviour, self-efficacy and social support, as well as body weight and composition will be compared between the two groups. This study will establish whether FIT-TEENS intervention is feasible and acceptable to overweight and obese adolescents in increasing their physical activity behaviour.
