Abstract:
Objective To explore the role of neck circumference (NC) in identifying central obesity. Methods A community-based cross-sectional survey was conducted from October 2010 to January 2011 in Shipai community,Guangzhou. A total of 1494 subjects(72.8%)aged over 50 were investigated. Height,weight,waist circumference (WC) and NC were measured in all subjects. Central obesity was defined by the standard in the 2013 China Guideline(WC≥90.0 cm for men or WC≥85.0 cm for women). Results The median age of 1473 subjects with complete data was 61 years(55~68 years). NC was significantly positively correlated with WC and body mass index(correlation coefficient was 0.639 and 0.565,respectively,P<0.001). ROC curves showed that the area under the curve for the ability of neck circumference to determine visceral adiposity was 0.884(95%CI:0.855 ~ 0.909,P < 0.0001)for men and 0.849(95%CI:0.824 ~ 0.872,P < 0.0001)for women. Moreover,in men ,a NC of 38.5 cm had a sensitivity of 75.2%and specificity of 85.4%,and in women ,a NC of 33.4 cm had a sensitivity of 84.8% and specificity of 69.4%,which were the optimal cutoffs for identifying central obesity. Conclusions NC could be used as an alternative for WC and body mass index to identify central obesity in Chi-nese subjects aged over 50 in community-based setting.
