成都市中老年人群体质指数与血脂相关性

Relationship between body mass index and blood lipid among middle-aged and elder persons in Chengdu city

目的探讨中老年人群体质指数(BM I)与血脂水平及脂代谢异常的关系。方法于2008年采用分层整群抽样的方法,抽取四川省成都地区40～79岁5 175名城乡居民进行身高、体重、血脂等测量,并问卷调查。结果成都地区中老年居民肥胖患病率为11.03%,其中男性为8.66%,女性为12.6%,超重率为35.07%,其中男性为35.7%,女性为34.7%;随着BM I的增加,中老年人群甘油三酯(TG)水平呈明显上升趋势,高密度脂蛋白胆固醇(HDL-C)水平呈明显下降趋势;中老年男性人群高TG血症患病率随BM I增加呈增高趋势;中老年女性人群高TG血症、高总胆固醇(TC)血症、低HDL-C血症患病率随BM I增加呈增高趋势。结论中老年人群TG及HDL-C水平、中老年男性高TG血症及女性高TG血症、高TC血症、低HDL-C血症患病率与BM I密切相关。

Objective To investigate the relationship between body mass index（BMI） and the levels of blood lipid and lipid metabolic disorder among middle-aged and elder people.Methods Stratified cluster sampling method was used and 5 175 persons aged 40-79 years in Chengdu city were selected for a questionnaire survey and measurements of height,weight,and blood lipid.Results The prevalence of obesity was 11.03%（8.66% for male and 12.6% for female） and that of overweight was 35.07%（35.70 for male and 34.70% for female） among the people.With the increase of BMI,triglyceride（TG） levels in the older aged groups showed an increase trend and high-density lipoprotein-cholesteral（HDL-C） levels showed an obvious decrease.With BMI increase,the middle-aged male showed a trend of high TG hyperlipidemia.The female showed a increase trend of high TG hyperlipidemia,high total cholesterol（TC）,and low HDL-C with the increase of BMI.Conclusion BMI is closely corelated with the incidences of high TG,high TC,low HDL-C among middle-aged and elder persons.
