Neck circumference as predictor of excess body fat and cardiovascular risk factors in adolescents

OBJECTIVE:To verify whether neck circumference can predict cardiovascular risk factors and excess body fat in adolescents.METHODS:This cross-sectional study included male and female adolescents aged 10 to 14 years from Viçosa, Minas Gerais. The following data were collected: anthropometric measurements, blood pressure, percentage of body fat according to dual energy X-ray absorptiometry, and levels of fasting glucose, fasting insulin, triglycerides, total cholesterol, high-density lipoprotein, and low-density lipoprotein. The anthropometric measurements were used for calculating indices and assessing nutritional status. The receiver operating characteristic curve tested whether neck circumference could predict cardiovascular risk. We also investigated how neck circumference related to the study parameters. The significance level was set at 5% (p0.5; p

**研究目的**：验证颈围能否预测青少年的心血管危险因素与体脂过剩情况。**研究方法**：本横断面研究纳入了来自米纳斯吉拉斯州维索萨市的10至14岁男女青少年。本次研究收集的观测数据包括：人体测量学指标、血压、双能X线吸收法（dual energy X-ray absorptiometry）测得的体脂百分比，以及空腹血糖、空腹胰岛素、甘油三酯、总胆固醇、高密度脂蛋白（high-density lipoprotein）、低密度脂蛋白（low-density lipoprotein）水平。通过采集的人体测量学数据计算相关指数并评估营养状况。采用受试者工作特征曲线（receiver operating characteristic curve）检验颈围能否预测心血管风险，并分析颈围与本研究各项参数的相关性。本研究设定显著性水平为5%（p0.5; p ）。
