城市社区30～70岁居民血脂异常影响因素的非条件Logistic回归分析

Non-conditional logistic regression analysis of influencing factors on lipid disorders of community residents aged 30～70

目的：探讨城市社区30～70岁居民血脂异常的状况和影响因素，为采取有效的干预对策提供依据。方法：采用流行病学现况调查方法，用分层整群抽样抽取年龄在30岁以上的居民进行问卷调查和实验室检查。结果：男性高TC血症、高TG血症、低HDL血症、高LDL血症的患病率分别为26．32％、39．69％、15．13％、20．41％；女性高TC血症、高TG血症、低HDL血症、高LDL血症的患病率分别为20．07％、31．55％、17．53％、14．11％。多因素非条件Logistic回归分析显示，超重肥胖（OR=5．557）、油腻饮食（OR=5．307）、高血压（OR=3．059）、腹部肥胖（OR=2．396）、糖尿病（OR=1．984）、年龄（OR=1．680）是血脂异常的危险因素，而素食（OR=0．534）和运动（OR=0．660）是血脂异常的保护因素。结论：城市社区居民血脂异常状况严重，应采取科学饮食、合理营养、加强锻炼、控制体重、提高健康知识水平、控制血压等关键性措施，以降低血脂异常的患病率。

Objective ：To explore the status and influencing factors of the lipid disorders in the town community residents at the age of 30--70 for providing the basis with available intervention measures. Methods ： By using epidemiology cross-sectional investigation, residents aged over 30 were selected with stratified cluster sampling for questionnaire and labo- ratory examination. Results：The prevalence rates of hypercholestero laemia, hypertriglyceridemia, low HDL and high LDL in male were 26. 32%, 39.69%, 15.13% and 20.41%, respectivdy, while that was seen in female with 20.07%, 31.55%, 17.53% and 14.11%, respec- tively. Multiple factor non-conditional logistic regression analysis showed that the risk factors were associated with overweight（ OR = 5. 557）, intake of greasy diet（ OR = 5. 307）, hypertension（ OR = 3. 059）, ab- dominal obesity（ OR =2. 396）,diabetes mdlitus（ OR = 1. 984）and age group （ OR = 1. 680）, but vegetarian eating （ OR = 0.534） and exercise（ OR = 0. 660） were the protective factors. Conclusion ： The findings suggest that community residents are in serious status of lipM disorders. The key measures to reduce the risk factors must be scientific diet, rational nutrition, aggressive exercise, weight control, improvement of health knowledge and blood pressure control.
