Objective: Ensuring adequate healthcare services for adolescents is very important because they experience significant changes of the body and mind and accelerated physical development occurs. Recently adolescent obesity has emerged as a serious social issue. Adolescent obesity can later lead to adult obesity which is linked to various kinds of adult diseases and complications. The purpose of this research aims to identify possible causal factors for the increase in prevalence of obesity among adolescents and investigate weight control and eating behavior of adolescents. Subjects and methods: This study is a secondary analysis using raw data from the 8th Youth Risk Behavior Web-based Survey organized by Korea Center for Disease Control and Prevention in 2012. The study was performed in a representative sample of 72,229 middle and high school students (37,229 boys and 35,000 girls), where the analysis of each subject's weight, height, and BMI based on gender and age was included. Data were analyzed with Chi-square test and multiple logistic regression using SAS program. Result: The overall prevalence of obesity was 9.2% (12.3% of boys and 5.7% of girls). The analysis showed that those being older, living with single mothers, having parents with lower levels of education, earning poor academic achievement, and being from lower economic background had high risk of obesity rate in general. Obesity rates associated with dietary habits and physical activity were high among frequent breakfast skippers, and those who spent less time in physical activity but much time in sedentary behavior. The average hours of sleep was 6.4 and those who were deprived of sleep had higher rates of obesity. Those who slept more than 8 hours per night had the lowest obesity rates. Higher levels of perceived stress were associated with higher obesity rate and subjects were suffering from stress mostly due to their appearances. 55.7% of obese group and 29.8% of non-obese group had been working on their weight. There were 17.9% (14.0% of boys, 21.0% of girls) practicing inappropriate methods of weight loss. The inappropriate methods of weight control include fasting, excessive use of medicines like laxatives or diuretics without prescription, vomiting after eating, one-food diet, intake of oriental medicine as diet food. Conclusion: Adolescent obesity is strongly correlated with the amount of sleep and the level of stress. Inappropriate methods of weight control have been attempted by many adolescents.
