摘要
目的：以生物电阻抗法（BIA）为效标,比较皮褶厚度法5种不同推导公式对汉族肥胖儿童少年体脂量的预测结果,探索适合检测肥胖儿童少年的体脂量评估公式。方法：将76名汉族肥胖儿童少年按性别和年龄分为4组,进行身高、体重、身体围度、皮褶厚度及生物电阻抗法测量,分别用相关分析与Bland-Altman分析,对Lohman公式、Brozek公式、Siri公式、Slaughter公式及国内公式对体脂量的预测结果与BIA法所得体脂量的相关性及一致性进行比较。结果：1）Brozek公式和Siri公式高估了被试的体脂量,而国内公式则低估了被试的体脂量;2）13~18岁女性肥胖者中Slaughter公式对体脂百分比的预测值与BIA法最接近,且相关性最高（R=0.833）,Bland-Altman分析偏倚差最小、limits of agreement也最低;3）Lohman公式高估了7~12岁男性肥胖者的体脂量,但低估了7~12岁女性肥胖者和13~18岁男性肥胖者的体脂量,提示该方法的不稳定性。结论：Slaughter公式所测13~18岁的女性肥胖者体脂量可做出与BIA最接近的体脂间接评估。
Objective： To study comparatively five different skinfold-thickness equations for predicting percentage body fat, and try to find out a relatively appropriate method to estimate body fat mass in obese children and adolescents of Han popu- lation. Methods：According to gender and age, 76 obese children and adolescents of Han population were divided into 4 groups, and were measured in body height and body weight, waist and hip circumference, skinfolds and bioelectrical imped- ance analysis（B/A）. Correlation and agreement between the skinfold-thickness equations involves Lohman, Brozek, Sift, Slaughter, and Chinese prediction equations and BIA. were analyzed. Results ： Firstly, Brozek equation and Sift equation o- verestimated body fat mass in all subjects, but Chinese prediction equation underestimated it. Secondly, for 13 ~ 18yrs girls, Slaughter equation best predicted body fat mass and gave the highest correlation（R = 0.833 ）and the lowest bias and limits of agreement compared with BIA. Thirdly ,Lohman equation overestimated body fat mass in 7 - 12yrs boys while underes- timated body fat mass in 7 - 12yrs girls and 13 ~ 18yrs boys, denoting the equation was not suitable for the test groups. Conclusion： Compared to other prediction equations through various types of skin fold thickness, it seems that Slaughter e- quation may be used in 13 ~ 18yrs female obese adolescents of Han population.
