Abstract

Background: Traditional anthropometric measures, including body mass index (BMI), are insufficient for evaluating the risk of diabetes. This study aimed to evaluate the performance of new anthropometric measures and a combination of anthropometric measures for identifying diabetes.

Methods: A total of 46 979 participants in the National Health and Nutrition Examination Survey program were included in this study. Anthropometric measures, including weight, BMI, waist circumference (WC), waist-to-height ratio (WtHR), conicity index (CI), and A Body Shape Index (ABSI), were calculated. Logistic regression analysis and restricted cubic splines were used to evaluate the association between the anthropometric indices and diabetes. The receiver operating characteristic (ROC) curve analysis was performed to compare the discrimination of different anthropometric measures.

Results: All anthropometric measures were positively and independently associated with the risk of diabetes. After adjusting for covariates, the per SD increment in WC, WtHR, and CI increased the risk of diabetes by 81%, 83%, and 81%, respectively. In the ROC analysis, CI showed superior discriminative ability for diabetes (area under the curve 0.714), and its optimum cutoff value was 1.31. Results of the combined use of BMI and other anthropometric measures showed that among participants with BMI <30 kg/m2 , an elevated level of another metric increased the risk of having diabetes (P < .001). Similarly, at low levels of weight, CI, and ABSI, an elevated BMI increased diabetes risk (P < .001).

Conclusions: WtHR and CI had the best ability to identify diabetes when applied to the US noninstitutionalized population. Anthropometric measures containing WC information could improve the discrimination ability.

目的: 包括体重指数(BMI)在内的传统人体测量方法不足以评估糖尿病的风险。这项研究旨在评估新的人体测量方法和人体测量方法的组合在识别糖尿病方面的表现。 材料和方法: 本研究共纳入46979名参加国家健康与营养调查项目的受试者。计算人体测量指标,包括体重、BMI、腰围(WC)、腰高比(WtHR)、圆锥度指数(CI)和身体形态指数(ABSI)。使用Logistic回归分析和限制三次样条法评估人体测量指标与糖尿病之间的关系。对受试者工作特征(ROC)曲线进行分析,比较不同人体测量指标的识别率。 结果: 所有人体测量指标均与糖尿病风险呈正相关且独立相关。校正协变量后,WC、WTHR和CI的每标准差增量分别使糖尿病风险增加81%、83%和81%。在ROC分析中,CI对糖尿病具有较好的鉴别能力(曲线下面积为0.714),其最佳临界值为1.31。体重指数和其它人体测量指标的联合使用结果显示,在BMI<30kg/m2 的参与者中,另一项指标的升高增加了患糖尿病的风险(P<0.001)。同样,体重、CI和ABSI值较低时,BMI升高会增加患糖尿病的风险(P<0.001)。 结论: 在美国非住院人群中,WtHR和CI识别糖尿病的能力最强。包含WC信息的人体测量指标可以提高辨别能力。.
