中文摘要：

目的了解某科研人群的生活方式、膳食结构,并研究血脂异常与生活方式和膳食结构的关系。方法对该科研单位的体检人群按1∶1配对进行病例-对照研究,分析调查因素与血脂异常的相关关系。结果多因素条件logistic回归分析表明,喜食油炸食品（OR=7.349）、禽类（OR=6.668）与肉类（OR=3.996）摄入量多、饮酒（OR=3.333）、血脂异常家族史（OR=10.302）和高BMI值（OR=1.165）等因素与血脂异常相关,是血脂异常的危险因素。而进食慢（OR=0.127）可能是血脂异常的保护因素。结论生活方式和膳食结构能影响血脂异常情况。

英文摘要：

[ Objective ] To study the life style and dietary structure of a research specialist staff, and investigate the relationship between life style and dietary structure. [Methods ] A 1：1 matched case-control study was conduct- ed to analyze the relationship between research factors and blood lipid of this population. [ Results ] Multiple condi- tional logistic regression analysis showed that there were several factors related with dyslipidemia, which were liking to eat fried foods （OR=7.349）, much poultry （OR=6.668） and meat （0R=3.996）, alcohol drinking （OR=3.333）, family history of dyslipidemia （OR=10.302） and high BMI level （OR=1.165）. Eating slowly was a potential protective factor against dyslipidemia （OR=0.127）. [ Conclusion ] Life style and dietary structure can affect the blood lipid level.
