辽宁省城乡成年居民血脂异常患病率及其危险因素分析

  目的分析辽宁省城乡成年居民血脂异常的患病率及其危险因素。方法抽取辽宁省城市及乡镇2989名年龄≥20岁的居民为研究对象，进行问卷、体格检查及血脂、血糖测定，计算血脂异常患病率并分析其危险因素。结果辽宁省成年居民血脂异常的患病率为51.6%，男性患病率为60%，女性患病率为47.4%。血脂异常的患病率随年龄的增加呈现上升趋势。在50岁以前，男性血脂异常的患病率明显高于女性，而50岁以后女性血脂异常的患病率明显高于男性。城市居民血脂谱的异常主要表现为总胆固醇、低密度脂蛋白胆固醇水平的增高和高密度脂蛋白胆固醇水平的降低，而乡镇居民血脂谱异常主要表现在甘油三酯水平的增高。多因素非条件Logistic回归分析显示男性、年龄增加10岁、吸烟、超重或肥胖、中心型肥胖、高血压、高血糖均为血脂异常的独立危险因素。结论辽宁省成年居民血脂异常的患病率已高达51.6%，城市及乡镇血脂谱异常的特点有所不同，应加强对血脂异常高危人群的防治。

The Prevalence and Risk Factors of Dyslipidemia among Urban and Rural Adults in Liaoning Province

Objective To investigate the prevalence and risk factors of dyslipidemia among urban and rural adult inhabitants in Liaoning.Methods 2 989 urban and rural adult inhabitants from Liaoning were chosen as the subjects.They answered the questionnaires,received physical examinations and their blood lipids and blood glucose determinations.The prevalence and risk factors of dyslipidemia were analyzed.Results The overall prevalence of dyslipidemia among adult inhabitants in Liaoning was 51.6%,the prevalence was 60% in male and 47.4% in female.The prevalence of dyslipidemia increased in accordance to aging.Before 50 years old,the prevalence in male was higher than that in female,but after 50 years old,it was just the opposite.In urban areas,the characteristics of dyslipidemia was an increase in total cholesterol and low density lipoprotein cholesterol and a decrease in high density lipoprotein cholesterol,while in rural areas,the characteristics of dyslipidemia was an increase in triglyceride.Logistic analysis showed that male,age increased by 10 years,smoking,overweight or obesity,central obesity,hypertension and hyperglycemia were independent risk factors for dyslipidemia.Conclusion The prevalence of dyslipidemia in Liaoning is 51.6%,the lipid profile in urban areas is different from that in rural areas,measures should be taken to prevent the people who are at higher risk from getting dyslipidemia.
