The Influence of Peer Support on the Nutritional Status of Adolescents at Madrasah Tsanawiyah in Sleman Regency

Overnutrition or obesity is a condition of increased body weight due to the accumulation of body fat, which is not only experienced by adults, but also by children and adolescents. The prevalence of overnutrition in adolescents continues to increase every year. One of the contributing factors is changes in diet, which are strongly influenced by the social environment, especially peer support. This research aims to determine the relationship between the influence of peer support and the status of overweight in adolescents. This research uses an observational design with a cross-sectional approach. The sample consisted of 20 students from the Sunan Pandanaran Sleman Madrasah Tsanawiyah who were taken using stratified random sampling. Data collection was carried out through the self-reported method to measure nutritional status and the peer support questionnaire to assess the influence of the social environment. The research was carried out in September 2024. The results of the analysis showed that 75% of the respondents were influenced by peer support in their nutritional status, while 25% were not. There is a significant relationship between peer support and overweight status in adolescents (p = 0.028). This research concludes that peer support plays a significant role in determining the nutritional status of adolescents. It is hoped that these findings will form the basis for the development of obesity intervention and prevention programs that consider aspects of the social environment, especially the role of peers.
