Abstract:
Objective To explore the optimal cutoff for waist circumference(WC)for defining central obesity,and its predictive ability for cardiovascular disease risk factors in Han adults in Xinjiang.Methods A cardiovascular risk survey(CRS)study was carried out from October 2018 to March 2021 with 14 618 representative participants selected,including 5757 Han adults.Complete data on 5666 participants were gathered.The age span of the participants was from 35 to 88 years old with the mean age as 52.47 years.Anthropometric data,blood pressure,serum concentration of serum total cholesterol,triglyceride,low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)and fasting glucose were documented.Prevalence rate,sensitivity,specificity and distance on the receiver operator characteristic(ROC)curve of each WC value were calculated.Results Both men and women,with the increase of waist circumference,the levels of systolic blood pressure,diastolic blood pressure,total cholesterol,triglycerides and fasting blood glucose are gradually increasing.In men,the prevalence of hypertension and hypertriglyceridemia increased as WC increased.In women,the prevalence of hypertension,diabetes,hypercholesterolemia and hypertriglyceridemia increased as WC increased.The shortest distance in the ROC curves for hypertension,dyslipidemia,diabetes,or≥2 of these risk factors suggested a WC cutoff of 90cm for men and 85cm for women.Conclusion The proportion of central obesity among Han adults in Xinjiang is higher than that of Han people in other regions.It is necessary to use a higher cutoff point value of waist circumference to define central obesity.
