摘要
目的 :分析 7岁以下单纯肥胖儿童体格发育特征 ,并评价体格测量参数在儿童期肥胖诊断中的价值。方法 :采用病例对照 1 :1配对的方法 ,对 1 4 0例 0～ 6岁单纯肥胖儿童体格测量参数进行分析。结果 :肥胖组腰围、臀围、大腿围及皮褶厚度明显大于对照组。腰 /臀围比、腰 /大腿围比两组间无差异 ,但肩胛下 /肱三头肌皮褶厚度比随年龄增大肥胖组显著大于对照组。肥胖指数 (OI)与体块指数 (BMI)和体重的直线相关系数分别为 0 .933 ,0 .483 ;多元回归方程 :OI =1 .885 +5 .0 0 7BMI +0 .343×体重 +3 .1 76×出生体重 +0 .2 79×三头肌皮褶厚度。结论 :单纯肥胖儿童从 4岁起躯干部脂肪开始增多 ,有发展为脂肪中央分布的趋势。OI值能综合反映儿童体格发育和体脂状况 ,是判断儿童肥胖的直观。
Objective:To evaluate the physical development of obese children younger than 7 years and the validation of anthropometric measurement parameters in diagnosis of childhood obesity. Methods: The anthropometric measurement parameters of 140 obese children 0～6 years of age were analyzed using case-control (1:1 matched) study. Results: Obese children had greater waistline, hip circumference, and thigh circumference and skinfold thinckness than the controls. There were no significantly differences between obese children and controls in the ratios of waistline to hip circumference (WHR) and to thigh circumference (WTR), however, the difference in the ratio of subscapular skinfold to triceps skinfold increased with age. The linear correlation coefficients of obesity index (OI) with body mass index (BMI) and with weight were 0.933 and 0.488 respectively. Multiple linear regression equation was as follows: OI=1.885+5.007BMI+0.343weight+3.176birth weight+0.279 triceps skinfold. Conclusion: Obese children had an increased fat mass at trunk after they were 4 years of age; there was a trend toward concentric accumulation of body fat with increasing age. OI is a valid index in diagnosis of childhood obesity because it can reflect the conditions of physical development and body fat.
