空军战斗机飞行员脂肪肝患病率及危险因素研究

Investigation on prevalence and risk factors of fatty liver in air force fighter pilots

目的:了解空军歼击机飞行员脂肪肝患病率及危险因素,以便采取预防措施。方法:对入院体检的662名男性歼击机飞行员进行肝脏B超检查,测身高、体重和清晨空腹血脂,并进行有关因素的调查登记。危险因素的确定采用单因素和多因素Logistic回归分析方法。结果:本组飞行员脂肪肝患病率为9.7%。脂肪肝的危险因素为:饮酒、体重指数、高甘油三酯血症、飞行总时间、年龄,其优势化(OR)值以饮酒为最高(11.60)。结论:空军歼击机飞行员脂肪肝患病率高于一般人群和民航飞行人员,应加强对可控危险因素的干预。

Objective：To investigate the prevalence and risk factors of fatty liver in air force fighter pilots. Methods：Six hundred and sixty two air force fighter pilots served as subjects. Liver ultrasonography, body weight, height and fasting blood lipid levels were measured. The related factors were investigated through questionnaire. Risk factors were determined by univariate and multivariate logistic regression analysis. Results：The fatty liver prevalence in this group of air force fighter pilots was 9.7%. The risk factors of fatty liver determined by multivariate analysis were enumerated in order of OR value as follows： alcohol drinking, body mass index（ BMI）, hypertriglyceridemia, total flying time, age. Odd ratio（OR） value of the leading risk factor alcohol drinking was as high as 11.60. Conclusion： As the incidence of fatty liver in air force fighter pilots is much higher than that of general population as well as civil aviators, the intervention on controllable risk factors must be enhanced in air force flying unit.
