中文摘要：

目的：了解广西巴马县长寿区与非长寿区老年人群的血脂水平及其危险因素。方法：采用分层随机抽样方法在广西巴马县长寿区和非长寿区分别抽取337名和189名60岁以上健康居民进行身高、体重、体重指数、腰围、血压、血清总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白-胆固醇（HDL-C）和低密度脂蛋白-胆固醇（LDL-C）测定,对血脂异常检出率危险因素进行非条件Logistic回归分析。结果：巴马长寿区老年人群血清TC、HDL-C水平明显高于非长寿区老年人群（P〈0.01）,而TG、LDL-C水平与非长寿区人群比较,差异无统计学意义（P〉0.05）。长寿区老年人群血脂异常检出率明显高于非长寿区人群（P〈0.01）。性别、血压和腰围是巴马长寿区老年人群血脂异常的危险因素,每周食用玉米次数与长寿区人群血脂异常检出率呈负相关。而性别、体重指数是巴马非长寿区老年人群血脂异常的危险因素。结论：巴马长寿区和非长寿区老年人群的血脂谱、血脂异常检出率及其危险因素存在明显差异,可能与他们的饮食习惯、生活方式不同有关。

英文摘要：

Objective： To determine serum lipid levels and the risk factors in Guangxi Bama elderly from longevity and non-longevity areas.Methods： A total of 337 healthy individuals（age≥60 years） from longevity area and 189 individuals from non-longevity area of Bama County were studied.Height,weight,waist circumference,blood pressure,serum levels of total cholesterol（TC）,triglyceride（TG）,high-density lipoprotein cholesterol（HDL-C）,low-density lipoprotein cholesterol（LDL-C） were measured,and body mass index（BMI） was calculated.An unconditional logistic regression analysis was also performed.Results： The levels of TC and HDL-C in longevity group were higher than those in non-longevity group（P0.01）,respectively,but there were no significant differences in the levels of TG and LDL-C（P0.05）.The prevalence of dyslipidemia in longevity group was also higher than that in non-longevity group（P0.01）.The risk factors of dyslipidemia were gender,blood pressure and waist circumference in longevity group.The prevalence of dyslipidemia was negatively correlated with corn consumption.The risk factors of dyslipidemia were gender and BMI in non-longevity group.Conclusion： The present study reveals significant differences in serum lipid profiles,the prevalence of dyslipidemia and the risk factors in elderly people from longevity and non-longevity areas of Bama County,which might result from different dietary habit and life style.
