OBJECTIVE
To estimate the accuracy of neck circumference measurement as a method of diagnosing excess weight of six and seven-year-old children.
METHODS
1026 six and seven-year-old children were included and anthropometric data were collected using cut-off points for the Body Mass Index (BMI) Z-score, in addition to the measurement of their neck circumference in centimeters. Pearson's correlation coefficient was used to assess the correlation between neck circumference and BMI. Sensitivity, specificity, positive and negative predictive values were calculated. The Receiver Operating Characteristic curve was used to measure the accuracy of neck circumference as a diagnostic method for excess weight.
RESULTS
A positive linear correlation value was observed between neck circumference and BMI 0.572 (p<0.001). The accuracy value of the global ROC curve was 0.772 (p<0.001). Sensitivity and specificity showed low values, but high positive predictive values were observed, especially between measures of 30 and 31cm.
CONCLUSION
Neck circumference showed accuracy of 77.2% as a diagnostic method for overweightness in six and seven-year-old children.
目的
评估颈围测量作为诊断 6-7 岁儿童超重的方法的准确性。
方法
纳入 1026 名 6-7 岁儿童，使用体重指数（BMI）Z 分数的截断点收集人体测量数据，以及颈围以厘米为单位的测量值。使用皮尔逊相关系数评估颈围与 BMI 之间的相关性。计算灵敏度、特异性、阳性和阴性预测值。使用受试者工作特征曲线（ROC 曲线）来衡量颈围作为超重诊断方法的准确性。
结果
颈围与 BMI 呈正线性相关，相关系数为 0.572（p<0.001）。总体 ROC 曲线的准确性值为 0.772（p<0.001）。灵敏度和特异性值较低，但阳性预测值较高，特别是在 30-31cm 的测量值之间。
结论
颈围作为 6-7 岁儿童超重的诊断方法，准确性为 77.2%。
