兴宁市公务员脂肪肝患病率及相关因素的调查

A SURVEY OF INCIDENCE AND RELEVANT FACTORS OF FATTY LIVER IN GOVERNMENT EMPLOYEES

目的:调查公务员脂肪肝患病率,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:测量993例体检人员的体重、身高、体脂含量、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、AC、CC、TG明显高于对照组(非脂肪肝患者),差异有统计学意义(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统计学意义,酗酒率差异有统计学意义。结论:公务员脂肪肝发病与性别、年龄、BMI、体脂含量、血脂水平有关。

OBJECTIVE：To investigate the incidence of fatty liver in government employees, and determine its epidemiologic characteristic and association with some nutrition variables such as BMI, body fat and so on. Methods ：993 subjects aged 21-60 are investigated, including the measurement of weight, height, arm circumference （ AC ） , calf circumference（CC） , blood examination of serum cholesterol （TC）and total triglycerides （TG） ,investigation of 24 hour dietary intake, and fatty liver determination by B - ultrasonography. The morbility of fatty liver was analysed 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 content, AC,CC and TG are higher in fatty liver patients than in control group（P 〈0.05）. TC is higher in male and female patients than non -fatty liver 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 - fatty liver patients. Conclusion：Fatty liver is associated with gender, BMI, skin fold, body fat percent and serum lipid levels.
