摘要

目的：預測以國際肥胖專案小組（IOTF）建議的體重過重與肥胖分類之韓國兒童體脂肪率（%BF）切點值與的一致性，並與那些已發表之高加索兒童數值比較。研究方法與程序：樣本由來自三個學校之1083名7-18歲韓國兒童以及青少年（555名男孩及528名女孩）組構。身體質量指數（BMI）以及%BF使用生物電阻分析儀測量。體重過重與肥胖的分類是依據IOTF指南之年齡別及性別的BMI切點。結果：預測體重過重與肥胖的%BF切點因年齡及性別而有所不同。17-22%男童及24-37%女童為過重，24-30%男童30-53%女童為肥胖。年齡較大的韓國男童%BF切點比起已發表的高加索男童%BF切點為低；而體重過重的韓國女童%BF切點與高加索女童則相似；韓國13-18歲肥胖女童的%BF切點比高加索女童的切點高。結論：韓國7-18歲的兒童之IOTF-對體重過重及肥胖建議BMI切點值與相關的%BF值，其切點可能需要針對年齡及性別分別訂定。

Objective: To predict the percent body fat (%BF) cutoff values corresponding to overweight and obesity recommended by the International Obesity Task Force (IOTF) in Korean children and to compare those values with the published cutoff values in Caucasian children. Research methods and procedures: The sample consisted of 1083 Korean children and adolescents (555 boys and 528 girls) aged 7-18 years from 3 schools. Body mass index (BMI) and %BF using a bioelectrical impedance analyzer were measured. The classification of overweight and obesity was based on the age- and sex-specific BMI cutoff values of the IOTF guidelines. Results: The predicted %BF cutoff values for overweight and obesity varied by age and sex: overweight, 17-22% in boys and 24-37% in girls; obesity, 24-30% in boys and 30-53% in girls. Those %BF cutoff values in older Korean boys tended to be lower than the published %BF cutoff values in Caucasian boys. While %BF cutoff values for overweight in Korean girls were similar to the values in Caucasian girls, %BF cutoff values for obesity in Korean girls aged 13~18 years were higher compared to cutoff values in Caucasian girls. Conclusion: The %BF values associated with the IOTF-recommended BMI cutoff values for overweight and obesity may require age- and sex-specific cutoff values in Korean children aged 7-18 years.
