摘要
目的探讨新疆汉族成年人群中心性肥胖最适腰围切点值,以及其对心血管疾病危险因素的预测能力。方法2018年10月至2021年3月开展新疆地区心血管风险调查,共选择具有代表性样本14618人,其中汉族5757人,从中选取资料完整的5666人作为研究对象,年龄35~88岁,平均(52.47±12.71)岁。测量并记录每名入组对象的血压、总胆固醇、甘油三酯、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、空腹血糖。计算并记录不同腰围值所对应的心血管疾病常见危险因素的患病率、敏感度、特异性及在受试者操作特征曲线上的距离,以受试者操作特征曲线判定腰围对中心性肥胖筛查的切点、敏感度、特异性和患病率。结果无论男性还是女性,随着腰围值的增长,收缩压、舒张压、总胆固醇、甘油三酯及空腹血糖的水平均呈逐渐上升的趋势。在新疆汉族成年男性中,高血压和高甘油三酯血症的患病率随着腰围的增大逐渐升高。在新疆汉族成年女性中,高血压、糖尿病、高胆固醇血症及高甘油三酯血症的患病率随着腰围值的增大呈逐渐升高的趋势。无论男性还是女性,其高血压、血脂异常、糖尿病或≥2个危险因素在受试者工作特征曲线上的最短距离定为最适腰围的切点值,男性为90cm,女性为85cm。结论新疆汉族成年人群中心性肥胖的比例比其他地区的汉族人群要高,需要采用较高的腰围切点值定义中心性肥胖。
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 14618 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.
