To identify the optimal waist:height ratio (WHtR) cut-off point that discriminates cardiometabolic risk factors in Turkish adults.
Cross-sectional study. Hypertension, dyslipidaemia, diabetes, metabolic syndrome score >or=2 (presence of two or more metabolic syndrome components except for waist circumference) and at least one risk factor (diabetes, hypertension or dyslipidaemia) were categorical outcome variables. Receiver-operating characteristic (ROC) curves were prepared by plotting 1 - specificity on the x-axis and sensitivity on the y-axis. The WHtR value that had the highest Youden index was selected as the optimal cut-off point for each cardiometabolic risk factor (Youden index = sensitivity + specificity - 1).
Turkey, 2003.
Adults (1121 women and 571 men) aged 18 years and over were examined.
Analysis of ROC coordinate tables showed that the optimal cut-off value ranged between 0.55 and 0.60 and was almost equal between men and women. The sensitivities of the identified cut-offs were between 0.63 and 0.81, the specificities were between 0.42 and 0.71 and the accuracies were between 0.65 and 0.73, for men and women. The cut-off point of 0.59 was the most frequently identified value for discrimination of the studied cardiometabolic risk factors. Subjects classified as having WHtR >or= 0.59 had significantly higher age and sociodemographic multivariable-adjusted odds ratios for cardiometabolic risk factors than subjects with WHtR < 0.59, except for diabetes in men.
We show that the optimal WHtR cut-off point to discriminate cardiometabolic risk factors is 0.59 in Turkish adults.
确定最佳腰围身高比（WHtR）切点，以区分土耳其成年人的心血管代谢危险因素。
横断面研究。高血压、血脂异常、糖尿病、代谢综合征评分≥2（除腰围外，至少有两种代谢综合征成分存在）和至少有一种危险因素（糖尿病、高血压或血脂异常）为分类结局变量。绘制 1-特异性在 x 轴上，敏感性在 y 轴上的接收者操作特征（ROC）曲线。选择具有最高 Youden 指数的 WHtR 值作为每个心血管代谢危险因素的最佳截断点（Youden 指数=敏感性+特异性-1）。
土耳其，2003 年。
检查了年龄在 18 岁及以上的成年人（1121 名女性和 571 名男性）。
ROC 坐标表分析表明，最佳截断值范围在 0.55 到 0.60 之间，在男性和女性之间几乎相等。确定的截断值的敏感性在 0.63 到 0.81 之间，特异性在 0.42 到 0.71 之间，准确性在 0.65 到 0.73 之间，男性和女性。区分所研究的心血管代谢危险因素时，0.59 是最常确定的截断值。WHtR≥0.59 的受试者与 WHtR<0.59 的受试者相比，年龄较大，社会人口统计学多变量调整后的心血管代谢危险因素比值较高，男性除外糖尿病。
我们表明，区分土耳其成年人心血管代谢危险因素的最佳 WHtR 截断值为 0.59。
