An Epidemiological Study on BMI and Blood Lipid Changes in Healthy Subjects Aged 35～64 in Guzhen Town,Zhongshan,Guangdong

目的探讨体质指数 (BMI)和肥胖率以及血脂变化趋势。方法分别于 1992年和 1996年在广东中山古镇进行了两次心脑血管病危险因素的调查。结果调查显示 :人群 BMI和肥胖率均以 1996年为高 ,呈上升趋势且上升幅度明显 ;人群 TC和 L DL - C水平及异常率呈下降趋势 ;HDL - C亦有所下降 ,但仍高于全国水平 ,特别是 4 5～ 5 4岁的男性 TG异常率有所升高 ;多元线性逐步回归方程所示 :BMI与腰围 \臀围 (WHR)、TG、SBP呈正相关。结论保持适中的体重成为当前预防心脑血管病重点之一 ,同时继续加强对高脂血症者的预防及控制仍十分必要。

Objective To explore the changing trend of BMI,obesity and hyperlipidemia in cardio cerebrovascular diseases.Methods Two epidemiological studies were conducted at 1992 and 1996,respectively,in Guzhen,Zhongshan,Guangzhou.Results From 1992 to 1996,BMI and obesity rates were significantly increased,and the serum TC,LDL C and their abnormal rate were decreased in the population aged 35 to 64.Although serum HDL C had also decreased,it was still higher than the average level of the whole country.The abnormal rate of serum TG in male aged 45~54 was still increased. With multifactor linear regression analysis,the results showed that WHR,TG and SBP were related with BMI.Our results suggested that at present,keeping proper weight become more important to the prevention of cardio cerebrovascular diseases.Conclusion It is necessary to prevent and control hyperlipidemia in proper way.
