Abstract：Objective To study the relation of neck circumference with MS and its components in the elderly .Methods A total of 4412 Renqu permanent residents aged 60-70 years were divided into group A (n=1115) with their neck circumference≤33 .80cm ,group B (n=1139) with their neck circumference being 33 .81-35 .80 cm ,group C (n=1143) with their neck circumference be‐ing 35 .81-38 .00cm ,and group D (n=1015) with their neck circumference>38 .00 cm .The cut point of neck circumference was analyzed according to the ROC curve by logistic regression analy‐sis .Results The BMI ,waist circumference ,blood pressure ,and serum FBG ,LDL‐C ,UA levels in‐creased while the serum HDL‐C level decreased with the increasing neck circumference (P<0 .05 , P<0 .01) .The cut point of neck circumference was 37 .75/34 .15 cm with a predictive accuracy of 78 .7% and 76 .1% respectively for MS in males and females .The detection rate of MS ,central obesity ,high TG ,low HDL‐C ,hypertension ,diabetes mellitus was significantly higher in patients with a higher cut point of neck circumference than in those with a lower cut point of neck circum‐ference (67 .41% vs 24 .93% ,84 .26% vs 30 .59% ,45 .95% vs 21 .98% ,55 .01% vs 31 .67% , 91.20% vs 80 .40% ,29 .33% vs 13 .89% ,P<0 .01) .Conclusion Neck circumference is closely related with MS and its components ,and plays an important role in early prediction and preven‐tion of MS .
