兴宁市公务员脂肪肝患病率及相关因素的调查

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.

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

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.
