Reports comparing waist circumference (WC) measurements from young populations are scarce.
We compared two protocols for measuring waist circumference in a sample of youth with diabetes.
Participants were enrolled in the SEARCH for Diabetes in Youth Study (SEARCH). WC was measured at least twice by the National Health and Nutrition Examination Survey (NHANES) protocol and twice by the World Health Organization (WHO) protocol. Method-specific averages were used in these analyses.
Among 6248 participants, the mean NHANES WC (76.3 cm) was greater than the mean WHO WC (71.9 cm). Discrepancies between protocols were greater for females than males, among older participants, and in those with higher body mass index (BMI). In both sexes and four age strata, the WCs using either method were highly correlated with BMI z-score. The within-method differences between the first and second measurements were similar for the two methods.
These analyses do not provide evidence that one of these two methods is more reproducible or is a better indicator of obesity as defined by BMI z-scores.
关于比较年轻人群腰围（WC）测量值的报告很少。
我们在一组患有糖尿病的青年样本中比较了两种测量腰围的方法。
参与者被纳入青少年糖尿病研究（SEARCH）。腰围至少按照美国国家健康与营养检查调查（NHANES）方法测量两次，以及按照世界卫生组织（WHO）方法测量两次。这些分析中使用了特定方法的平均值。
在6248名参与者中，NHANES测量的平均腰围（76.3厘米）大于WHO测量的平均腰围（71.9厘米）。两种方法之间的差异在女性中比男性更大，在年龄较大的参与者中以及体重指数（BMI）较高的参与者中也是如此。在两个性别和四个年龄层中，使用任何一种方法测量的腰围与BMI z评分都高度相关。两种方法第一次和第二次测量之间的方法内差异相似。
这些分析没有提供证据表明这两种方法中的一种更具可重复性，或者是BMI z评分所定义的肥胖的更好指标。
