Background:
Sedentary behavior in adolescents is a major pediatric health concern. Prolonged inactivity can negatively affect physical and mental health, potentially leading to body image distortion, especially among adolescents. This study aims to explore the relationship between sedentary behavior and body image distortion in adolescents, considering sedentary purpose and sex differences.
Methods:
This study analyzed data from the 2021-2023 Korea Youth Risk Behavior Survey (KYRBS), comprising 150,025 middle and high school students. Sedentary time was self-reported as the average daily sedentary duration over 7 days. Body image distortion was defined as a discrepancy between the body mass index and perceived body image of participants. Data analysis included descriptive statistics, chi-square tests, and logistic regression, stratified by sex and sedentary purpose. Increased sedentary behavior was significantly associated with body image distortion.
Results:
Among female adolescents, educational sedentary time had a stronger effect on body image distortion (odds ratio: 1.06, 95% confidence interval: 1.02-1.09). In contrast, male adolescents showed no significant association.
Conclusions:
This study highlights the significant association between sedentary behavior and body image distortion in adolescents. Future research should further explore the long-term effects of sedentary behavior on the physical and mental health of adolescents.
