The shift in diet and physical activity in modern society has resulted in obesity becoming a public health problem. This problem will be a burden to the state if it is not addressed early on. This study aims to examine and find models of obesity determinants based on consumption, physical activity, lifestyle, social and environmental factors. The sample was randomly selected for elementary school children in the city of Denpasar. The collected data were analyzed by using a structural equation model. Of the 375 elementary school children in the city of Denpasar, it is known that 35.5% are overweight, even one-third of them have entered the obesity stage. Consumption factors have the dominant contribution in increasing the risk of obesity. In the next order, other factors emerged: social factors; lifestyle; physical activity; followed by environmental factors. As a follow-up plan from the results of this study, a Digital-Based Nutrition Care Process for Obese Children will be designed which can later be disseminated on all mass line platforms as an intervention plan. Although the application is designed to be disseminated through the mass line platform, the role of the teacher is still needed to monitor the progress of this program.
