To evaluate the correlation between neck circumference and insulin resistance and components of metabolic syndrome in adolescents with different adiposity levels and pubertal stages, as well as to determine the usefulness of neck circumference to predict insulin resistance in adolescents.
Cross-sectional study with 388 adolescents of both genders from ten to 19 years old. The adolescents underwent anthropometric and body composition assessment, including neck and waist circumferences, and biochemical evaluation. The pubertal stage was obtained by self-assessment, and the blood pressure, by auscultation. Insulin resistance was evaluated by the Homeostasis Model Assessment-Insulin Resistance. The correlation between two variables was evaluated by partial correlation coefficient adjusted for the percentage of body fat and pubertal stage. The performance of neck circumference to identify insulin resistance was tested by Receiver Operating Characteristic Curve.
After the adjustment for percentage body fat and pubertal stage, neck circumference correlated with waist circumference, blood pressure, triglycerides and markers of insulin resistance in both genders.
The results showed that the neck circumference is a useful tool for the detection of insulin resistance and changes in the indicators of metabolic syndrome in adolescents. The easiness of application and low cost of this measure may allow its use in Public Health services.
评估不同肥胖水平和青春期阶段青少年的颈围与胰岛素抵抗及代谢综合征各组分之间的相关性，并确定颈围对预测青少年胰岛素抵抗的效用。
对388名年龄在10至19岁的青少年进行横断面研究。这些青少年接受了人体测量和身体成分评估，包括颈围和腰围，以及生化评估。青春期阶段通过自我评估获得，血压通过听诊获得。胰岛素抵抗通过稳态模型评估-胰岛素抵抗来评估。通过调整体脂百分比和青春期阶段的偏相关系数评估两个变量之间的相关性。通过受试者工作特征曲线测试颈围识别胰岛素抵抗的性能。
在调整体脂百分比和青春期阶段后，颈围与男女的腰围、血压、甘油三酯及胰岛素抵抗标志物均相关。
结果表明，颈围是检测青少年胰岛素抵抗和代谢综合征指标变化的有用工具。该测量方法应用简便且成本低廉，可能使其适用于公共卫生服务。
