摘　　要：目的探讨老年人群颈围与中心性肥胖的相关性。方法对南昌市部分社区2820例老年人（≥60岁）颈围、身高、体质量、腰围、臀围进行检测，以腰围、体质指数2项肥胖标准进行分组，分析颈围与肥胖关系。采用Enter法进行多元线性回归分析，以ROC曲线分析法判断中心性肥胖颈围的切点。结果（1）老年人身高、体质量、体质指数均随年龄增长而下降（P趋势〈0．05），腰臀比随年龄增长而增大（P趋势〈O．01）；男性颈围随年龄增长而下降（P趋势〈0．01），女性腰围随年龄增长而增大（P趋势〈0．01）；（2）平均颈围男性为（36．5±3．0）cm，女性为（32．6±2．4）cm，男性大于女性（P〈0．01）；（3）老年人颈围分别随体质量、腰围和体质指数增加而增大（均P〈0．05），体质量每增加1kg，颈围增加0．079cm（男）和0．139cm（女）；腰围每增加1cm，颈围增加0．073cm（男）和0．040cm（女）；体质指数每增加1kg／m2，颈围增加0．121cm（男）和0．065cm（女）；男性年龄每增加1岁，颈围减小0．033cm；（4）按体质指数、腰围两项肥胖标准诊断，超重肥胖组的颈围均大于正常组（均P〈0．01）；（5）颈围与中心性肥胖诊断的R0c曲线下面积，男性为0．802，女性为0．743；最佳切点男性为36．85cm，女性为31．75cm。结论老年人颈围随体质量、腰围和体质指数增加而增大，颈围与中心性肥胖存在显著相关；男性颈围〉36．85cm，女性颈围〉31．75cm时可以预测中心性肥胖。Objective To investigate the association between the neck circumference and central obesity in the elderly. Methods The neck circumference（NC）, height, weight, waist circumference （WC） and hip circumference （HC） of 2820 subjects aged over 60 years were detected from some communities in Nanchang. All subjects were divided into different groups, according to the two different obesity indicators of WC and BMI. The relationship between NC and obesity was analyzed. A multiple linear regression analysis was conducted using the Enter method. An ROC curve analysis was employed to judge the tangent point of NC in central obesity. Results The height, weight and BMI were reduced along with age （all P〈0.05）, and the waist hip ratio（WHR） was increased along with age（P〈0.01） in the elderly. The NC was decreased along with age in males（P〈0.01）, and the WC was increased along with age in females（Pt〈0.01）. The NC was longer in males than in females [（36.5±3.0） em vs. （32.6±2.4） cm, P〈0.01]. The NC was increased along with body weight, WC and BMI in the elderly： with each 1 kg increase in body weight, the NC was increased by 0. 079 cm in males and 0. 139 em in females; with each lcm increase in WC, the NC increased by 0. 073 cm in males and 0. 040 cm in females; with each 1 kg/m2 increase in BMI, the NC increased by 0. 121 em in males and 0. 065 cm in females; with 1 year increase in age, the NC was decreased by 0. 033 cm in males（all P〈0.05）. when obesity was diagnosed according to both BMI and NC, the NC was longer in the obesity group than in the control group, （P〈 0.01）. The area under receiver operating characteristic（ROC） curve of NC for diagnosing central obesity showed that the area was 0. 802 and 0. 743 in males and females, and the optimal cut-off value of NC was 36.85 cm and 31.75 cm in males and females, respectively. Conclusions NC is increased along with the increases of body weight,WC and BMI in the elderly. NC is significantly associated with cen
