Aim:To study relation between distribution characters of the fatty liver with diabetes,coro-nary heart disease,hypertension,and related influence factors of fatty liver in middle-aged and old peo-ple in urban community.Methods:It has been collected which include relevant medical data of 1 795 residents who participated in collective medical physical examination,and which also include the historys of smoking,drinking,bland diet,high blood pressure,diabetes and coronary heart disease,family histo-ry of fatty liver and other indicators with fatty liver disease.Results:The standardized prevalence rate of fatty liver was 24.75%,(29.1 5% in men and 22.76% in women).Diabetes prevalence was 7.83%, hypertension prevalence rate was 7.83%,the incidence of coronary heart disease was 6.81%;Detection in the patients with fatty liver accompanied by high blood pressure was up to 36.3%(OR=2.090).De-tection in the patients with fatty liver accompanied by diabetes was up to 45.0%(OR=2.602).Detec-tion in the patients with fatty liver accompanied by coronary heart disease (CHD)was 33.1% (OR=1.526);The available data were analyzed by multi-factorial non-conditional Logistic regression method. Seven factors were identified,i.e.BMI,FBG,TG,family history of diabetes,coronary heart disease, movement and family history of fatty liver.Conclusion:Fatty liver and high blood pressure,high blood sugar,cardio-cerebrovascular disease such as coronary artery disease tend to coexist.BMI,FBG,TG, family history of diabetes,coronary heart disease,and fatty liver and fatty liver disease have a significant positive correlation separatively,motionis protective factors of fatty liver.more attention need to be paid to the prevention and cure of fatty liver in chronic disease management.%目的：探讨城市社区内中老年人群中脂肪肝与糖尿病、冠心病、高血压患病分布特点及脂肪肝患病的相关影响因素．方法：收集广州市参加集体体检的某社区1795个居民的体检资料，比较脂肪肝与高血压、糖尿病及冠心病在人群分布的特点，以及人群的体质量指数（BMI）、尿酸（UA）、血清胆固醇（TC）、甘油三酯（TG）、谷丙转氨酶（ALT）、低密度脂蛋白胆固醇（LDL-C）、高密度脂蛋白胆固醇（HDL-C）、空腹血糖（FBG）、吸烟、饮酒、清淡饮食、脂肪肝家族史等指标与脂肪肝发病的关系．结果：年龄标化后脂肪肝检出率为24.75％，其中男性29.15％，女性为22.76％．糖尿病患病率为7.83％，高血压患病率为22.38％，冠心病患病率为6.81％；在确诊有高血压的患者中检出伴有脂肪肝的比例高达36.3％（OR ＝2.090）、糖尿病患者中检出伴有脂肪肝的比例为45.0％（OR ＝2.602），冠心病患者中伴有脂肪肝的比例为33.1％（OR＝1.526）；采用Logistic 回归模型进行多因素分析，BMI、FBG、TG、糖尿病、冠心病、运动和脂肪肝家族史与脂肪肝患病有显著相关性．结论：脂肪肝与高血压、高血糖、冠心病等心脑血管病有并存的倾向；BMI、FBG、TG、糖尿病、冠心病及脂肪肝家族史与脂肪肝患病有显著正相关性，运动是脂肪肝的保护性因素，社区慢病管理中需要更多关注脂肪肝的防治．
