目的探讨宜兴地区18岁以上体检人群体重指数(BMI)与脂质代谢之间的关系。方法对2007年1月-2008年12月在宜兴市人民医院体检中心接受年度查体的1652例健康成人进行横断面调查,测定BMI、血清甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C),分析BMI与血脂异常的相关性。结果本组体检人群中超重和肥胖的发生率为45.34%和12.95%,血脂异常发生率为56.30%;男性BMI肥胖和超重的发生率和血脂异常的发生率均显著高于女性(P<0.05);男性肥胖/超重组BMI和TG均显著高于正常组,HDL-C明显低于正常组,女性肥胖/超重组BMI和LDL-C均显著高于正常组,超重组TG明显高于正常组;肥胖、超重人群血脂异常的发病率明显高于正常人群(P<0.05)。结论近年来宜兴地区超重、肥胖和血脂异常的发病率较高;超重肥胖者易伴随着脂质代谢异常,随着体重指数的增加,血脂异常的发病率明显增高。
Objective To explore the relationship between body mass index (BMI) and lipid metabolism in over 18 years old population in Yixing district. Methods From January 2007 to December 2008, a total of 1,652 healthy adults who underwent physical examination in Yixing Municipal People’s Hospital were examined by cross-sectional investigation. The levels of BMI, serum triglyceride (TG), total cholesterol (TC) Density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C), the correlation between BMI and dyslipidemia was analyzed. Results The incidence of overweight and obesity was 45.34% and 12.95% respectively in this group of people and the rate of dyslipidemia was 56.30%. The prevalence of obesity and overweight and the incidence of dyslipidemia in male BMI were significantly higher than those in female (P <0.05 ). The BMI and TG of male obesity / overweight group were significantly higher than those of the normal group, HDL-C was significantly lower than the normal group, BMI and LDL-C of the obese / overweight group were significantly higher than that of the normal group Group. The incidence of dyslipidemia in obese and overweight group was significantly higher than that in normal population (P <0.05). Conclusion The prevalence of overweight, obesity and dyslipidemia in Yixing area is high in recent years. Overweight and obese patients are easily accompanied by abnormal lipid metabolism. With the increase of body mass index, the incidence of dyslipidemia is significantly higher.
