서울시 학교 주변의 식품환경과 청소년 식생활 및 비만 관련성

Abstract

Objectives: The obesity rate among adolescents in Korea is continuously increasing. This study aimed to examine the relationship between dietary habits and obesity in Korean adolescents by focusing on the food environment around schools in Seoul. Methods: We used data from the 2020 Korea Youth Risk Behavior Survey and 2021 administrative data. In total, 7,691 middle and high school students from four regions in Seoul were included. Multilevel logistic regression analysis was performed to examine the effects of individual level and food environment factors around schools affecting adolescent obesity. Results: Adolescents in the southeastern region of Seoul had higher fruit intake and lower obesity rate compared to others. As a result of multilevel logistic regression analysis, sex and school had a significant effect on adolescent obesity in individual level factors. In school level factors, the number of convenience stores and fast food restaurants around the schools had a significant effect on adolescent obesity. Conclusion: The food environment around schools influenced adolescent dietary habits and obesity in that they spend most of their time in schools. Based on the results, there is need for ordinance enactment and promotion of related policies on improving the food environment around schools to form proper adolescent dietary habits and reduce Korean adolescent obesity.
