한국 청소년의 인터넷 사용 수준이 건강상태(BMI)에 미치는 영향

Abstract

Objectives The purposes of this study were to investigate the socio-demographics, health and dietary factors, and health status (BMI) of Korean adolescents according to their internet usage level, using data from the 2019 Korea Youth Risk Behavior Web-Based Survey. Additionally, the study aimed to examine the relationship between internet usage level and the risk of obesity.
 Methods For this purpose, the raw data from the 2019 KYRBS was analyzed, and a total of 57,302 individuals were selected as the study subjects. To analyze the differences in socio-demographics, health and dietary factors, and health status (BMI) according to the level of internet usage, Rao-Scott χ2 test was used, and logistic regression analysis was used to calculate the odds ratios (OR) and 95% confidence intervals (95% CI) for the risk of obesity according to internet usage level.
 Results This study found that adolescents who overused the internet were more likely to be female, middle school students, and have lower parental education and economic status. They also showed unhealthy dietary and lifestyle behaviors, including high alcohol consumption, low physical activity, irregular breakfast, inadequate fruit and vegetable intake, inadequate milk and water intake, excessive consumption of sugary drinks and fast food, and rely on convenience food instead of regular meals. They had a higher risk of obesity compared to non-internet users.
 Conclusions This study was able to explain the association between internet usage level and obesity, and found that the group that overused the internet had a higher risk of obesity compared to the group that non-internet users.
