Neck circumference (NC) is a predictive measure for the diagnosis of Metabolic Syndrome (MS). The aim of the present study was to establish cutoff points for NC as a predictor of the presence of MS in Brazilian rural workers, based on the MS components according to the IDF and NCEP-ATP III criteria. This is a cross-sectional study carried out with rural workers in the municipality of Santa Maria de Jetibá, in the state of Espírito Santo, Brazil. The ROC curve was calculated and the cutoff points for predicting the risk of developing MS were stipulated from the NC, identified by the area under the curve, using different methods of criteria for determining MS. Sensitivity, specificity, positive and negative predictive values and Youden index were applied. The significance level adopted was 5%. The cutoff points were different for males, resulting in 39.550 cm (AUC 0.832) according to the NCEP-ATP III criterion and 39.125 cm (AUC 0.888) according to the IDF criterion. For women, the cutoffs were similar, resulting in a single cutoff of 34.725 cm (AUC 0.862 for NCEP-ATP III and 0.849 for IDF). The cutoff points defined for men and women for NC showed good sensitivity and specificity for predicting MS in the studied population. The NC measurement proved to be a simple, low-cost and accurate measure for assessing this morbidity in Brazilian rural workers.
颈围（NC）是诊断代谢综合征（MS）的一项预测指标。本研究的目的是根据国际糖尿病联盟（IDF）和美国国家胆固醇教育计划成人治疗组第三次报告（NCEP-ATP III）标准中的MS组分，确定巴西农村劳动者中作为MS存在预测指标的颈围切点。这是一项对巴西圣埃斯皮里图州圣玛丽亚·德热蒂巴市农村劳动者开展的横断面研究。计算了ROC曲线，并根据曲线下面积确定的颈围，采用不同的MS判定标准方法规定了预测发生MS风险的切点。应用了灵敏度、特异度、阳性和阴性预测值以及约登指数。采用的显著性水平为5%。男性的切点不同，根据NCEP-ATP III标准为39.550厘米（AUC 0.832），根据IDF标准为39.125厘米（AUC 0.888）。对于女性，切点相似，得出单一切点为34.725厘米（NCEP-ATP III的AUC为0.862，IDF的AUC为0.849）。为男性和女性定义的颈围切点在预测研究人群的MS方面显示出良好的灵敏度和特异度。颈围测量被证明是评估巴西农村劳动者这种发病率的一种简单、低成本且准确的方法。
