虽然腰围可以提供重要的代谢风险信息，但逻辑问题阻碍了它在门诊实践中的常规应用。我们评估了自我测量腰围是否足够准确，以取代专业测量腰围识别high-risk patients.METHODS医疗门诊患者和研究参与者自我测量腰围在同一次访问期间，专业测量腰围获得。参与者被提供标准化的关于如何测量腰围的图片指导，专业人员接受标准化的培训。结果收集了585名妇女的自我和专业测量腰围数据（平均+/- SD年龄= 40 +/- 14岁，平均+/- SD体重指数= 27.7 +/- 6.0 kg/m2）和165名男性（平均+/- SD年龄= 41 +/- 14岁，平均+/- SD体重指数= 29.3 +/- 4.6 kg/m2）。虽然自我和专业测量腰围没有显着差异，我们发现一个临床重要的假阴性率自我测量。11%的正常体重女性和52%的超重女性有专业测量的腰围，使她们处于代谢综合征的高风险类别（即大于88厘米）;然而，这些女性中分别有57%和18%的人低估了她们的腰围，因为腰围低于临界值。分别有15%和84%的超重和I级肥胖男性的腰围是经过专业测量的，（即大于102厘米）;然而，这些男性中分别有23%和16%测量不足腰围，自我测量的假阴性率接近或超过20%的一些群体在高风险的健康状况不佳的结果。
PURPOSE Although waist circumference can provide important metabolic risk information, logistic issues inhibit its routine use in outpatient practice settings. We assessed whether self-measured waist circumference is sufficiently accurate to replace professionally measured waist circumference for identifying high-risk patients.METHODS Medical outpatients and research participants self-measured their waist circumference at the same visit during which a professionally measured waist circumference was obtained. Participants were provided with standardized pictorial instructions on how to measure their waist circumference, and professionals underwent standard training.RESULTS Self-and professionally measured waist circumference data were collected for 585 women (mean +/- SD age = 40 +/- 14 years, mean +/- SD body mass index = 27.7 +/- 6.0 kg/m(2)) and 165 men (mean +/- SD age = 41 +/- 14 years, mean +/- SD body mass index = 29.3 +/- 4.6 kg/m(2)). Although self-and professionally measured waist circumference did not differ significantly, we found a clinically important false-negative rate for the self-measurements. Eleven percent of normal-weight and 52% of overweight women had a professionally measured waist circumference putting them in a high-risk category for metabolic syndrome (ie, greater than 88 cm); however, 57% and 18% of these women, respectively, undermeasured their waist circumference as falling below that cutoff. Fifteen percent and 84% of overweight and class I obese men, respectively, had a professionally measured waist circumference putting them in the high-risk category (ie, greater than 102 cm); however, 23% and 16% of these men, respectively, undermeasured their waist circumference as falling below that cutoff.CONCLUSIONS Despite standardized pictorial instructions for self-measured waist circumference, the false-negative rate of self-measurements approached or exceeded 20% for some groups at high risk for poor health outcomes.
