45岁以上中老年农民脂肪肝的患病情况及相关因素分析

目的分析中老年农民群体的脂肪肝患病情况，探讨其发病的相关因素。方法对参加健康体检的1700名农民，测量体重、身高及血压，测血脂、血糖及乙肝表面抗原（HBsAg）等，进行腹部B超、心电图和胸透等检查，比较脂肪肝组与非脂肪肝组的差异。结果脂肪肝患病率为16．35％，女性略多于男性（P〈0．01）；老年组脂肪肝的患病率与中年组比较无统计学差异（P〉0．10）；脂肪肝组中并存肥胖症、高血压病及糖尿病的检出率显著高于非脂肪肝组（P〈0．01）。脂肪肝组的血脂异常主要为甘油三酯（TG）升高及高密度脂蛋白胆固醇（HDL—c）降低，与非脂肪肝组比较差异有显著性（P〈0．01）。结论脂肪肝的发病可能与性别、嗜酒、肥胖、高血压病、糖尿病、高TG血症和低HDL—c血症有关。

The Prevalence and Related Factors of Fatty Liver in Farmers over 45 Year Old

Obiective To investigate the prevalence and related factors of fatty liver in the farmers over 45 years old. Methods Health checkups were performed in 1700 farmers and the following data were collected; weight, height, blood pressure, blood cholesterol, blood triglyceride （TG）, high density lipoprotein, （HDL-c）, low density lipoprotein（LDL-c）, HBsAg, the results of ultrasonic scanning of the abdomen, electrocardiogram and chest X-ray check. The differences of those data between farmers with and without fatty liver were compared. Results The prevalence of fatty liver diagnosed by ultrasonic scanning was 16.35%, and women with higher prevalence than men （P〈0.01）. However, the prevalence in the old-and the middle-aged subjects were almost the same（P〈0.01）. Obesity, hypertension and diabetes were more frequent in fatty liver group. Comparing with the non-fatty liver subjects, the increase of TG and LDL-c and the decrease of the HDL-c were more frequent in ones with fatty liver （P〈0. 01）. Conclusion the prevalence of fatty liver is related with gender, alcohol addiction, obesity, hypertension, diabetes, higher TG and lower HDL-c.
