Abstract
Objectives: The aim of the study was to validate the utility of neck circumference (NC) as an anthropometric measure of the central obesity and its correlation with body mass index (BMI) and waist circumference (WC). The aim of the study was to determine age and gender specific NC cutoffs for screening central obesity. Materials and Methods: This descriptive study was conducted in 1139 children and adolescents aged 6–17 years. NC, WC, and BMI were measured. To define overweight and obesity in children, the 23rd and 27th adult equivalent lines for BMI as presented in the revised Indian Academy of Pediatrics growth charts were used. Results: Overweight and obese children had significantly higher NC than those with normal BMI (p<0.001). NC showed a positive correlation with both WC and BMI (p<0.001). In children aged <12 years, NC cutoff for screening obesity was 26.5 cm in both boys (sensitivity 83.3% and specificity 71.7%) and girls (81.4% and 70.5%). The area under the curve for NC was greater than that of WC in both boys (0.86 vs. 0.76) and girls (0.82 vs. 0.66). In children aged 12–17 years, NC cutoff values were 34 cm in boys (sensitivity 83.33% and specificity 75.60%) and 31 cm in girls (94.34% and 83.29%). The area under curve for WC was greater than that of NC in boys (0.94 vs. 0.88) and almost similar in girls (0.96 vs. 0.95). Conclusions: NC can accurately identify children with a high BMI. It is a better anthropometric measure than WC in identifying prepubertal children with central obesity. In children aged 12–17 years, it can be considered a good alternative for screening central obesity.
目的:本研究的目的是验证颈围(NC)作为中心性肥胖的人体测量指标的效用及其与体重指数(BMI)和腰围(WC)的相关性。该研究的目的是确定年龄和性别特异性NC临界值,以筛查中心性肥胖。材料和方法:本描述性研究纳入了1139名6-17岁的儿童和青少年。测量NC、WC和BMI。为了定义儿童的超重和肥胖,使用了修订后的印度儿科学会生长图表中提供的第23和27条成人等效BMI线。结果:超重和肥胖儿童的NC明显高于BMI正常儿童(p<0.001)。NC与WC、BMI均呈正相关(p<0.001)。在<12岁的儿童中,男孩(敏感性83.3%,特异性71.7%)和女孩(81.4%,特异性70.5%)筛查肥胖的NC临界值均为26.5 cm。NC的曲线下面积在男孩(0.86比0.76)和女孩(0.82比0.66)中均大于WC。在12-17岁的儿童中,男孩的NC临界值为34 cm(敏感性83.33%,特异性75.60%),女孩为31 cm(94.34%,特异性83.29%)。男孩WC的曲线下面积大于NC (0.94 vs. 0.88),女孩WC的曲线下面积几乎相同(0.96 vs. 0.95)。结论:NC可准确识别高BMI儿童。它是鉴别青春期前儿童中心性肥胖的较好的人体测量指标。在12-17岁的儿童中,它可以被认为是筛查中心性肥胖的一个很好的选择。
