摘要

Background: The number of overweight or obese early teenagers has increased rapidly in the past decade in Taiwan, but the main risk factors for this have not been determined. Our objective was to evaluate food intake, exercise, and lifestyle in overweight or obese early teenagers.
Methods: We used random and cluster sampling methods to screen approximately 200 teenagers from different grades at junior high schools in Taichung, Taiwan. A total of 587 early teenagers (51% boys, 49% girls; aged 12-15 years) participated in this study, which included questionnaire, physical, and blood chemistry evaluations.
Results: \Approximately 25% of the subjects met the criteria for overweight or obese (based on 85% or 95% of the body mass index for age, respectively). The proportion of boys was higher than girls (27.3% vs 23.5%; P＜0.05). Approximately 7% of boys and 2.5% of girls had metabolic syndrome. The prevalence of obesity and metabolic syndrome in early teenagers of higher grades was much higher than that in those of lower grades. Behavior relating to obesity included a lack of exercise of moderate to vigorous intensity (＜ 3 h/wk; P＜0.05), computer use (＞ 2 h/day; P＜0.05), and intake of sugarcontaining drinks (soft drinks; ＞ 5/wk; P＜0.05). Obese girls reported the least amount of exercise and the highest consumption of sugar-containing drinks, and obese boys spent more time on the computer. Obese boys had low androgen levels, but thin girls also had low androgen levels. These 2 groups also reported shorter sleep times (＜ 6 h/day; P＜0.05, P＜0.01, respectively).
Conclusion: Lack of exercise and excessive intake of sugar-containing drinks, as well as amount of sleep and time spent on the computer, are associated with early teenager obesity in Taiwan.
