背景资料：由于青少年的身体组成比成人变化更大，人体测量参数经常用于儿童体脂测量，因此我们在德国青少年中开发了腰围（WC）、臀围（HC）、腰高比（WHtR）、腰臀比（WHR）和皮褶厚度（SFT）的年龄、性别和种族特异性参考值。1633名男孩和1391名女孩年龄在12-18岁的代表性样本参加了这项横断面研究。体重，身高，体重指数（BMI），WC，HC，WHR，WHtR，和SFT进行测量和平滑;年龄，性别和种族特定的参考曲线开发使用LMS方法。超过14岁的男性明显比女性更重，更高。雌性动物的SFT总和持续增加（+20%），且显著高于雄性动物（7.4 mm）。在第90百分位数时，男性的SFT三头肌减少（-12%），但女性增加（+11%）;两种性别的SFT肩胛下肌增加。从12岁到18岁，WHtR和WHR保持不变，而WC和HC在两个性别中增加。WHtR是男性腹型肥胖的最佳预测因子（曲线下面积[AUC] 0.974 +/- 0.004）和雌性（AUC 0.986 +/- 0.003），然后是体脂百分比（AUC 0.937 +/- 0.008），雄性和WHR（AUC 0.935 +/- 0.009）。结论：这些SFT、WC、HC、WHR和WHtR的年龄和性别特异性百分位数曲线来自德国青少年的大型全国样本，可能有助于开发腰围和其他成人肥胖预测因子的国际参考值。世界儿科杂志2011;7（1）：16-23
Background: Because the body composition of adolescents varies more than that of adults and anthropometric parameters are regularly used for pediatric body fat measurements, we developed age-, gender-, and ethnicity-specific reference values for waist circumference (WC), hip circumference (HC), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), and skinfold thickness (SFT) in German adolescents.Methods: A representative sample of 1633 boys and 1391 girls aged 12-18 years participated in this cross-sectional study. Weight, height, body mass index (BMI), WC, HC, WHR, WHtR, and SFT were measured and smoothed; age-, gender-, and ethnicity-specific reference curves were developed using the LMS method.Results: Females were significantly heavier than males at 12 years. Beyond age 14 males were significantly heavier and taller than females. The SFT sum increased continuously (+20%) in females and was significantly higher (7.4 mm) than in males. At the 90th percentile, SFTtriceps decreased (-12%) in males but increased (+11%) in females; SFTsubscapular increased in both genders. From 12 to 18 years, WHtR and WHR remained constant, whereas WC and HC increased in both genders. WHtR was the best predictor for abdominal obesity in males (area under the curve [AUC] 0.974 +/- 0.004) and females (AUC 0.986 +/- 0.003), followed by body fat percentage (AUG 0.937 +/- 0.008) in males and WHR (AUC 0.935 +/- 0.009) in females.Conclusion: These age- and gender-specific percentile curves for SFT, WC, HC, WHR, and WHtR, derived from a large national sample of German adolescents, may be useful for developing international reference values for waist circumference and other predictors of adult obesity.
