汉族和朝鲜族居民不同类型肥胖与心血管代谢危险因素的关系

目的 分析延边地区朝鲜族和汉族居民不同类型肥胖与心血管代谢危险因素的关系.方法 于2006年8月～2008年8月在吉林省延边农村地区随机抽取30～70岁朝鲜族和汉族人群5842人,测其身高、体重、腰围( waist circumference,WC)等指标,同时采集清晨空腹(禁食12h)静脉血,并准确测定生化指标.结果 1)30～70岁人群肥胖粗患率汉族和朝鲜族分别为12.2％和8.7％,年龄调整患病率分别为11.2％和9.8％,汉族均高于朝鲜族(x2=18.09,P＜0.001; U=39.43,P＜0.001);汉族和朝鲜族腹型肥胖粗患病率分别为46.4％和44.8％,年龄调整患病率分别为41.8％和40.9％,调整患病率汉族高于朝鲜族(U=17.64,P＜0.001).2)不同性别及民族心血管代谢危险因素及其聚集性与体质指数(body mass index,BMI)水平、WC关联与否及其程度有所不同.3)Logistic分析结果表明,高血压、高血糖(朝鲜族)、高胆同醇(total cholesterol,TC)(汉族)、低高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)(汉族)、非HDL-C、高甘油三酯(triglyceride,TG)和代谢综合征(metabolic syndrome,MS)在BMI和WC均异常组的aRR值最大；单纯BMI异常组的aRR值大于单纯WC异常组的心血管代谢危险因素为高血压(朝鲜族)、低HDL-C(汉族)和非HDL-C(朝鲜族)；而单纯WC异常组的aRR值大于单纯BMI异常组的心血管代谢危险因素则为高血压(汉族)、高血糖、高TC(朝鲜族)、高TG和MS.结论 吉林省延边地区一般人群肥胖患病水平较高,而且不同民族人群不同类型肥胖患病率存在明显的差异.BMI、WC及其合并组表现出不同的心血管代谢风险.

Relationship between different types of obesity and the risk factors of cardiovascular metabolism in different nationalities of Yanbian Area

Objective To analyze the relationship between different types of obesity and the risk factors of cardiovascular metabolism in Korean and Han nationality of Yanbian Area.Methods 5 842 rural residents aged 30～70 years were finally selected,and the anthropometric and biochemical indexes were measured.Results 1）The crude prevalence of obesity was 12.2% in Han and 8.7% in Korean,and the age-adjusted prevalence was 11.2% and 9.8%,respectively,and all appeared to be higher in Han than in Korean（χ2=18.09,P0.001;U=39.43,P0.001）;the crude prevalence of abdominal obesity was 46.4% and 44.8%,and the age-adjusted prevalence was 41.8% and 40.9%,respectively,and the age-adjusted prevalence in Han was significantly higher than that in Korean（U=17.64,P0.001）.2）There was a disparity in relationship between different types of obesity and the risk factors of cardiovascular metabolism by sex and race.3）In overweight/obesity group combining with abdominal obesity,the aRR of hypertension,hyperglycemia（Korean）,high-TC（Han）,low-HDL-C（Han）,non-HDL-C（korean）,high-TG and MS showed the highest value;compared with the isolated abdominal obesity group,the aRR of hypertension（Korean）,low-HDL-C（Han） and non-HDL-C（Korean） showed the higher value in isolated overweight/obesity group;compared with the isolated overweight/obesity,the aRR of hypertension（Han）,hyperglycemia,high-TC（Korean）,high-TG and MS showed the higher value in isolated abdominal obesity.Conclusions The prevalence rate of different type＇s obesity is comparatively high in this area and its difference between Korean and Han nationality is significant.The effect of body mass index（BMI）,waist circumferencec（WC） and its combination on the risk of cardiovascular metabolism is different.
