【摘要】 目的 调查公务员中脂肪肝的患病率，探讨脂肪肝的流行病学特征及其与BMI、体脂含量等营养指标的关系。方法 993例体检人员被调查，测量他们的体重、身高、体脂含量、肱三头肌皮褶厚度、上臂围、小腿围和血脂，进行24h膳食调查，采用B超诊断脂肪肝。按性别、年龄段分组比较脂肪肝的患病率，并分析各项营养指标与脂肪肝患病的关系。结果 男性脂肪肝的发病率明显高于女性(男性32.0%，女性9.9%，P<0.01)；女性脂肪肝的患病率随年龄增长明显升高( P<0.01)，男性大于30岁人群中脂肪肝的患病率明显升高( P< 0.05)；脂肪肝患者的BMI、W、Fat%、TSF、AC、CC、TG明显高于对照组(非脂肪肝患者)，差异有显著性(P<0.05)，男性脂肪肝组的TG高于对照组(P<0.05)。脂肪肝与对照组比较24h膳食营养素摄入量差异无显著性，酗酒率差异有显著性。结论 公务员的脂肪肝发病与性别、年龄、BMI、皮褶厚度、体脂含量、血脂水平有关。

    【Abstract】 Objective To investigate the incidence of fatty liver in officials, and determine its epidemiologic characteristic and association with some nutrition variables such as BMI, body fat percent and so on.Methods 993 subjects are investigated(aged 21～60 years), including the measurement of weight, height, body fat percent(FP%), triceps skin fold(TSF), arm circumference(AC), calf circumference(CC), blood examination of serum cholesterol (TC)and total triglycerides(TG), investigation of 24 hour dietary intake, and diagnosing fatty liver by B-ultrasonography. Analyze the morbility of fatty liver by age and gender, and the association between nutrition variables and fatty liver.Results The morbility of fatty liver is higher in males than females (32.0% vs 9.9%, P<0.01). In females, the morbility increases with age (P<0.01); while in males, it significantly increases after 30 years old (P<0.05). BMI, weight, body fat percent, TSF, AC, CC and TG is higher in fatty liver patients than in non-patients (P<0.05). TC is higher in male and female patients than non-patients, but the statistic significance is only seen in male (P<0.05). There is no statistic difference for the dietary nutrients intake obtained by 24 hours review, and significant difference for excessive alcoholic drinking rate between patients and non- patients and shows.Conclusion Fatty liver is associated with gender, BMI, skin fold, body fat percent and serum lipid levels. ......
