目的:调查重庆市老年人群高脂血症患病情况及影响因素,为重庆市老龄人群社会医疗预防工作提供可靠的科学依据。设计:以诊断为依据、社区为基础的横断面研究。地点、对象和方法:采用随机整群抽样,抽取重庆市社区60岁以上人口4915人进行调查。血脂分析抽取静脉血2mL,相关影响因素采用问卷调查,查体确定伴发疾病。主要观察指标:重庆市社区老年人血脂水平及高脂血症患病率与年龄、性别的关系及患高脂血症与相关因素的关系。结果:4915名受试者中,431名(8.77%)为高胆固醇血症,703名(14.30%)人为高低密度脂蛋白血症,772名(15.71%)为高三酰甘油血症。血清总胆固醇、三酰甘油和低密度脂蛋白胆固醇(low-densitylipoproteincholesterol,LDL-C)随年龄增长而增高,而高密度脂蛋白胆固醇(high-densitylipoproteincholesterol,HDL-C)则随年龄增长而降低。体重超重者以及有吸烟、饮酒史者的高脂血症患病也显著增高。结论:重庆市社区老年人高胆固醇血症、高三酰甘油血症和高低密度脂蛋白胆固醇血症的患病率随年龄增高而增高,且男性高于女性。高龄、男性、超重和吸烟、饮酒是高脂血症的危险因素。
Objective: To investigate the prevalence and influencing factors of hyperlipidemia in the elderly population in Chongqing, and to provide a reliable scientific basis for prevention and treatment of social medical problems for the elderly in Chongqing. Design: Diagnostic-based, community-based cross-sectional study. Location, Subjects and Methods: Random cluster sampling was used to survey 4915 people over the age of 60 in Chongqing’s community.

MAIN OUTCOME MEASURES: The relationship between the level of blood lipid, the prevalence of hyperlipidemia, age and sex, and the relationship between hyperlipidemia and related factors in the elderly in community of Chongqing were analyzed. Results: Of the 4915 subjects, 431 (8.77%) had hypercholesterolemia, 703 (14.30%) had HDL, and 772 (15.71%) had hypertriglyceridemia. Serum total cholesterol, triglyceride and low-density lipoprotein cholesterol (LDL-C) increased with age, while high-density lipoprotein cholesterol (HDL-C) decreased with age. Overweight and those who have smoking, drinking history of hyperlipidemia also significantly higher. Conclusion: The prevalence of hypercholesterolemia, hypertriglyceridemia and high and low density lipoprotein cholesterol in the elderly in community of Chongqing is higher with the increasing of age, and the male prevalence is higher than that of female. Elderly, male, overweight and smoking, drinking is a risk factor for hyperlipidemia.
