Objective To provide better health management for pilots by retrospective study of the disease spectrum of China Southern pilots in 2017. Methods The retrospective study method was applied to estimate the detection rate of related disease of 1 826 pilots who participated in the physical examination in 2017.The detection rates of related diseases were compared among 4 age groups (20-29 yrs ,30-39 yrs ,40-49 yrs and ＞50 yrs). Results Among 1 826 pilots ,the top ten diseases were hyperlipidemia ,fatty liver ,hyperuricemia ,presbyopia ,gallbladder polyp ,ametropia , hearing loss ,obesity ,vision loss and renal cysts.Among different age groups ,the detection rates of hyperlipidemia ,fatty liver ,hyperuricemia ,presbyopia ,gallbladder polyp ,ametropia ,hearing loss , obesity ,vision loss ,renal cysts and hypertension were significantly different (χ2＝10.456-193.402 , P＜0.05).And the detection rates of fatty liver ,hearing loss ,obesity ,renal cysts and hypertension increased with age significantly. Conclusions The risk factors of cardiovascular disease in pilots are prominent.And the detection rates of the metabolic related diseases and the decreased audio-visual function are high in them.Controlling the body weight ,uric acid and blood lipid would be critical to pilot′s health management.

Objective To provide aeromedical management reference for preventing and controlling the overweight and obesity in pilots by a retrospective analysis on body mass index (BMI) and related diseases for the pilots of a civil airline in 2015.Methods The method of retrospective study was applied on 3 134 civil pilots who accepted annual physical examination in 2015 and were grouped by age.The detection rate of abnormal body mass index (BMI≥24 kg/m2) was compared among different age groups and the relationship between BMI and age was analyzed.The pilots also grouped by the level of BMI.The prevalence rate of hypertension,hyperlipidemia and other diseases were compared among different BMI groups,as well as such physiological and biochemical indexes as total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C) and fasting plasma glucose (FPG).Results Age and BMI of the civil aviation pilots were weak positive correlation (r=0.232,P＜0.05).The detection rate of hypertension,hyperlipidemia,combined hyperlipidemia familial,hyperuricemia,fatty liver,impaired glucose tolerance and diabetes increased significantly with the increasing of BMI (x2 =7.783-476.795,P＜0.05).The age and physiological and biochemical indexes of TC,TG,HDL,LDL-C and FPG were significantly different among different BMI groups (F=16.046-157.706,P＜0.05).Conclusions BMI is an important risk indicator for hypertension,fatty liver,hyperlipidemia and diabetes.The individualized management of controlling the pilot's BMI in a normal range is an important measure to prevent the cardiovascular diseases.

Objective To provide the scientific basis for the prevention and control of hypertension by analyzing the related risk factors for prolonging pilot's career.Methods Two thousand seven hundred and fifty-five pilots examined in 2013 were divided into different groups by age to compare the abnormal rate of blood pressure among groups.Such biochemical indicators as the prevalence of hyperglycemia and the hyperlipidemia were also analyzed for the comparison of normal blood pressure and hypertension.Results In 2 755 examined pilots,the cases of primary hypertension were 71 cases,and the prevalence rate was 2.58％.Prevalence of hypertension significantly increased with age (x2=64.704,P＜0.01).Triglyceride (TG),fasting plasma glucose (FPG),body mass index (BMI) in hypertension group was significantly higher than that in normal blood pressure group (t=3.173-5.684,P＜0.01).Conclusions Age,BMI,blood fat and blood sugar level are the significant risk factors of hypertension in civil aviation pilots.Prevention and control of the risk factors of the cardiovascular disease could be useful to restrict pilot's hypertension.

Objective To analyze the characteristics and development of disease spectrum of civil aircrews in the annual physical examinations,and to provide scientific basis for the civil aeromedical support in the future.Methods The annual physical examination data of the civil aircrews from 2009-2013 were analyzed in the constitution of the major diseases,and the trend of high incidence diseases in recent 5 years.The high disease incidence differences were compared by different post,age and time of flight.Results In the annual physical examination analysis,the detection rate of ametropia was the highest,followed by hyperlipidemia and fatty liver.The top 10 diseases in 2013 were ametropia,hyperlipidemia,fatty liver,hyperuricemia,hearing loss,gallbladder polyps,presbyopia,lumbar disc herniation,arrhythmia and hypertension.The detection rate of hyperuricemia increased year by year,the rate in 2013 was significantly higher than the rate in 2009 (x2 =198.28,P＜ 0.01).The detection rate of ametropia,fatty liver,gallbladder polyps in 2013 was significantly higher than the rate in 2009 (x2 =56.27,13.98,8.12,P＜0.01).The detection rate of hearing loss,presbyopia,lumbar disc herniation showed significant downtrend from 2009 to 2013 (x2=10.24,44.99,30.58,P＜0.01).Hyperlipidemia,fatty liver,hyperuricemia,hearing loss,gallbladder polyps,presbyopia,arrhythmia and hypertension were common in pilots (x2=73.62-1 940.13,P＜0.01).Ametropia and lumbar disc herniation were common in flight attendants (x2 =1 869.64,43.48,P＜0.01).Incident of hyperlipidernia,fatty liver,gallbladder polyps,hearing loss,presbyopia and hypertension significantly increased with age and flight time (P＜0.01).Conclusions Knowing the high incident disease spectrum of the aircrews with different jobs,age and time of flight will benefit to establishing personal health maintenance for aircrews and improving the level of aeromedical support.
