The waist-to-height ratio (WHtR) assesses abdominal adiposity and has been proposed to be of greater value in predicting obesity-related cardiovascular health risks in children than BMI. The present study aims to develop WHtR cut-offs for overweight and obesity based on the 85th and 95th percentiles for the percentage body fat (%BF) in a cohort of children and adolescents.
Waist circumference (WC), height, triceps and subscapular skinfolds were used to calculate WHtR and %BF. Correlations between WHtR and %BF and WHtR/mid-abdominal skinfold were made. Receiver-operating characteristic (ROC) curve analysis was used to select WHtR cut-offs to define overweight and obesity. Subjects were grouped by WHtR cut-offs, and mean values for anthropometry, blood lipids and blood pressure (BP) variables were compared.
Australian primary and secondary schools.
A total of 2773 male (M) and female (F) subjects of the 1985 Australian Health and Fitness Survey, aged 8-16 years.
Correlation coefficients between WHtR and %BF were M: r = 0.73, F: r = 0.60, P < 0.01 and WHtR/mid-abdominal skinfold were M: r = 0.78, F: r = 0.65, P < 0.01. WHtR of 0.46(M) and 0.45(F) best identified subjects with > or = 85th percentile for %BF and 0.48(M) and 0.47(F) identified subjects with > or = 95th percentile for %BF. When comparing the highest WHtR group to the lowest, both sexes had significantly higher means for weight, WC, %BF, TG (male subjects only), systolic BP (female subjects only) and lower means for HDL cholesterol (P < 0.05).
WHtR is useful in clinical and population health as it identifies children with higher %BF at greater risk of developing weight-related CVD at an earlier age.
腰高比（WHtR）评估腹部肥胖，并且已被提出在预测儿童肥胖相关心血管健康风险方面比 BMI 更有价值。本研究旨在根据儿童和青少年体脂百分比（%BF）的 85 百分位和 95 百分位，为超重和肥胖制定 WHtR 切点。
腰围（WC）、身高、肱三头肌和肩胛下皮褶用于计算 WHtR 和 %BF。WHtR 与 %BF 以及 WHtR/中腹部皮褶之间的相关性。使用接收者操作特征（ROC）曲线分析选择 WHtR 切点来定义超重和肥胖。根据 WHtR 切点将受试者分组，并比较体测、血脂和血压（BP）变量的平均值。
澳大利亚小学和中学。
1985 年澳大利亚健康与健身调查中共有 2773 名男性（M）和女性（F）受试者，年龄 8-16 岁。
WHtR 与 %BF 的相关系数分别为 M：r = 0.73，F：r = 0.60，P < 0.01，WHtR/中腹部皮褶的相关系数分别为 M：r = 0.78，F：r = 0.65，P < 0.01。WHtR 为 0.46（M）和 0.45（F）最佳识别出体脂百分比超过或等于 85 百分位的受试者，WHtR 为 0.48（M）和 0.47（F）最佳识别出体脂百分比超过或等于 95 百分位的受试者。当比较最高 WHtR 组和最低 WHtR 组时，男女的体重、WC、%BF、TG（男性受试者）、收缩压（女性受试者）均显著升高，HDL 胆固醇均显著降低（P < 0.05）。
WHtR 在临床和人群健康中很有用，因为它可以识别出体脂百分比更高、更早患与体重相关的 CVD 风险更高的儿童。
