The role of digital health interventions in reducing obesity among primary school children: A behavioural insights perspective

This study investigates the effectiveness of a web application called "Jejak BMI 1.0" aimed at reducing obesity among primary school students by promoting healthier behaviours in children and their parents. The research objectives were to assess the usability and user experience of the application, and to evaluate its impact on children's Body Mass Index (BMI) and parental behaviours. Using a mixed-methods approach, including pre- and post-test surveys, statistical analysis, and thematic analysis, the study found significant improvements in parental behaviours and children's BMI scores. The app was well-received by participants, with high usability and functionality ratings. Despite the positive outcomes, limitations such as the short study duration and potential biases were noted. The findings underscore the potential of digital tools in public health interventions and the importance of parental involvement in addressing childhood obesity.
