Intrarater reliability and measurement error associated with waist and hip circumference measures performed by a novice rater with one measurement were examined and compared among Body Mass Index (BMI) subgroups in a convenience sample of 76 participants (25 men, 51 women; M age = 47.2 yr., SD = 14.2). A rater blinded to the purpose of the study, as well as to the tape measure results, received training and then performed hip and waist circumference measures twice with a 10-min. interval. Intrarater reliability of the measures was acceptable (ICC3,1 > .95) across the BMI subgroups; measurement error was found to be greater in the overweight and obese subgroups. If a test-retest change score is greater than 3.0 cm in waist circumference and 2.0 cm in hip circumference, it can be assumed to be a true change with 95% confidence.
本研究便利选取了 76 名参与者（25 名男性，51 名女性；平均年龄 = 47.2 岁，标准差 = 14.2），考察了一位新手评估者仅进行一次测量时，腰围和臀围测量的组内可靠性和测量误差，并比较了这些数据在身体质量指数（BMI）亚组中的差异。一位对研究目的以及卷尺测量结果均不知情的评估者在接受培训后，以 10 分钟的间隔，对臀围和腰围进行了两次测量。在整个 BMI 亚组中，这些测量的组内可靠性是可以接受的（ICC3,1 ＞.95）；超重和肥胖亚组的测量误差较大。如果腰围的测试-再测试变化分数大于 3.0 厘米，而臀围的变化分数大于 2.0 厘米，则可以在 95%的置信水平下假设该变化是真实的。
