Abstract:
BACKGROUND: To investigate the association between childhood obesity and its risk factors according to specific childhood developmental stages. METHODS: We performed an analysis of data for 1922 children and adolescents aged 2 to 18 years obtained from the Third Korea National Health and Nutrition Examination Survey conducted in 2005. Weight and height were measured by trained interviewers. Childhood obesity was defined as BMI > or =95th percentile of the BMI cut-off point based on the Korean child growth curve. Data on socioeconomic characteristics such as age, education, occupation, income, physical activity and time spent watching television were collected using a well-established questionnaire and/or interview. RESULTS: The prevalence of obesity defined by using the Korean child growth curve was 4.1% in children aged 2 to 6, 6.3% in children aged 7 to 12, and 8.7% in adolescents aged 13 to 18. In the multiple logistic regression model, parental obesity, and time spent watching television were associated with increased risk of obesity in children aged 2~6. Parental obesity, family income level, birth weight, and time spent watching television were positively associated with obesity in children aged 7~12. In adolescents aged 13~18, participation in vigorous physical activity and attempts to control weight were associated with adolescent obesity. CONCLUSION: The prevalence and risk factors of childhood obesity vary substantially according to developmental stage. Differential approaches are needed for effective control of childhood obesity.
