目的:通过分析不同肥胖评价指标与三酰甘油(triglyceride,TG)、高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)、总胆固醇(total cholesterol,TC)及低密度脂蛋白胆固醇(low density lipoprotein cholesterol,LDL-C)水平间的相关性,选择一种简单、有效的肥胖评价方法。方法 :本研究共纳入吉林省长春地区9 273名研究对象,测量体重、身高、腰围和臀围,计算体质量指数(body mass index,BMI)、腰围身高比值、腰围臀围比值,并依据现有的诊断标准计算肥胖患病率;同时进行血清TG、HDL-C、TC及LDL-C水平测定,计算肥胖评价指标与血脂指标的相关系数r。结果:吉林省长春地区40岁以上成人的肥胖患病率为18.8%,超重患病率为43.7%,腹型肥胖患病率为64.78%。腰围与TG间的相关性(r=0.229)及与HDL-C间的相关性(r=-0.327)均高于其他肥胖评价指标与血脂间的相关性。结论:腰围是一种简单、准确的评价肥胖程度的指标,有较高的预测脂代谢异常的价值。
OBJECTIVE: To investigate the relationship between different obesity indicators and triglyceride (TG), high density lipoprotein cholesterol (HDL-C), total cholesterol (TC) and low density lipoprotein cholesterol density lipoprotein cholesterol, LDL-C) levels, select a simple and effective method for the evaluation of obesity. Methods: A total of 9 273 subjects were surveyed in Changchun, Jilin Province. Body weight, height, waist circumference and hip circumference were measured. Body mass index (BMI), waist circumference ratio, Some diagnostic criteria to calculate the prevalence of obesity; simultaneous determination of serum TG, HDL-C, TC and LDL-C levels, obesity and lipid indicators to calculate the correlation coefficient r. Results: The prevalence rate of obesity among over-40-year-olds in Changchun, Jilin Province was 18.8%, the prevalence of overweight was 43.7%, and the prevalence of abdominal obesity was 64.78%. The correlation between waist circumference and TG (r = 0.229) and the correlation with HDL-C (r = -0.327) were higher than those between other obesity indexes and blood lipid. Conclusion: Waist circumference is a simple and accurate index to evaluate the degree of obesity, which has a higher value of predicting abnormal lipid metabolism.
