ABSTRACT
Obesity is a nutritional problem that still occurs today. One of the causes of the high prevalence of obesity in adolescents is the habit of consuming low-nutrient foods or so-called junk food. Some of the research findings during the initial survey found that out of 1,178 students in a school in Medan City, 69 students were at risk of obesity. Students who are obese admit that they often consume junk food when they come home from school and during school holidays. This study aims to determine the effect of junk food advertising exposure, consumption patterns and physical activity to the incidence of obesity in adolescents in Medan City. This type of research uses the case control study method which is carried out at State Senior High Schools in Medan City from November 2020 to completion. The population in this study were all State Senior High School adolescents in Medan City who were active, namely 19,294 adolescents. The sample size was 362 teenagers. The analysis of this research used multivariate analysis. The results showed that there was a significant effect between exposure to junk food advertising exposure (p=0.047), consumption patterns (p=0.001) and physical activity (p=0.017) to the Incidence of Obesity in Adolescents in Medan City. It is suggested to the central government that regulations governing restrictions on junk food advertising, especially at peak watching time for adolescents, are recommended to reduce the risk of obesity in adolescents, and for adolescents whose nutritional status is obese, they should start losing weight by paying attention to their daily diet which is healthy.
