某部飞行员脂肪性肝病调查及风险因素分析

目的了解部队飞行员脂肪性肝病发病状况、探索发病风险,为防治提供依据。方法以某部现役飞行员为调查对象,采用问卷调查方式;并测量体质量、身高、肝功、血脂、血糖等;彩色多普勒超声检查肝脏。结果 682例飞行员共检出脂肪性肝病141例,检出率为20.7%。30岁以下组、31-40岁组、41岁以上组发病率分别为6.4%、22.5%、43.6%。脂肪肝组平均体质量、血甘油三酯含量和代谢综合征发病率均明显高于正常组（P〈0.01,P〈0.05）。结论在现役飞行员中脂肪性肝病检出率较高,脂肪性肝病患者容易合并代谢综合征。体质量增加、高脂血症、年龄是脂肪肝发病危险因子。

Prevalence and the associated risk factors of fatty liver in military aircrews

Objective To investigate the prevalence and associated risk factors of fatty liver in military pilots and navigators.Methods Aircrews were randomly selected for questionnaire and physical exams,later of which included real-time ultrasonography,blood testing for glucose and triglyceride concentrations as well as measurement of body mass index（BMI）.Results 682 military aircrews were selected for the investigation.141（20.7%） air crews had fatty liver diagnosis.The prevalence of fatty liver was 6.4 %,22.5 % and 43.6 % for aircrews younger than 30 years old,aged 31~40 and 41 years or over,respectively.The aircrews diagnosed with fatty liver group had significantly higher BMI,the prevalence of metabolic syndrome and the concentration of triglyceride than those in healthy group（P0.05）.Conclusion The prevalence of fatty liver was high in military aircrews and associated with overweight,hypertriglyceridemia and increasing of age.
