Rehabilitation application program for obesity adolescent using structural equation modelling

Abstract

Obesity is one of the most important public health problems of the late twentieth century. Report by World Health Organization (2015) found the national prevalence of obesity in Indonesia was increased from 12.2% in 2007 to 16.8% in 2015 and reached 11.9% for the aged 6 to 12 years old. This research is conducted to identify the factors influencing obesity and their impact on obese adolescent. There are five influencing factors; nutrition, genetic, physical activity, socioeconomic, health awareness. This research was conducted in Padang, West Sumatera, Indonesia including 386 students in the age of 11-15 years old. Results of Partial Least Square Structural Equation Modelling analysis shows that there are 16 indicators from 47 indicators that provide a significant impact on each factor they represent. The significant indicators include; snack consumption, nap schedules, and pocket money. In addition to that, analysis results on factors that affect obesity in adolescents show that the nutrition factor has the most influence on obesity adolescent with T = 5.911 followed by genetic = 4.321, physical activity = 3.174, and socioeconomic = 2.283. Meanwhile health awareness factor does not significantly affect on obesity in adolescents. However, the role of health awareness can be seen based on the correlation test results whereby all factors such as nutrition have the largest correlation with health awareness factors. The results of these statistical analysis will be used as a reference for the content on rehabilitation application program for obesity in adolescents. The validity and usability test for the developed application program shows most of users were satisfied with the program. However, there were several users that found difficulty in using english based application. The result of this research can be a reference for the authority and nutritionist in making guidelines or treatment in order to prevent the increase of obesity among adult and adolescents.
