Abstract：Objective To analyze influence factors of blood homocysteine (Hcy) concentration of military flight personnel,and provide the basis for health management in normal life and training.Methods A total of 110 flight personnel from transport aircraft,bomber,helicopter pilots (41 of which with the flight time≤1000 h,69 with the flight time＞t000 h),86 fighter pilots (33 of which with the flight time ≤1000 h,53 with the flight time＞1000 h) and 107 healthy ground crew were selected.All flight personnel and healthy ground crew were divided into three groups according to age,respectively (20-30,31-40 and older than 41 years old),and different types of flight personnel were divided into two subgroups according to flight time(≤1000 h or＞1000 h),meanwhile their blood Hcy concentration were compared.Results HCY concentration of military flight personnel was significantly higher than that of healthy ground crew (F =10.1 75,P =0.000),and the blood Hcy concentration of 31-40 years old flight personnel was significantly higher than that of 20-30 years old flight personnel.As the flight time increased,the HCY concentration increased(P＜0.05).Blood Hcy concentration had relationship with blood uric acid,triglyceride and cholesterol.Conclusion For military flight personnel,the blood Hcy concentration of 31-40 and 20-30 years old flight personnel are significantly higher than those of healthy ground crew,and increase with flight times.Blood Hcy concentration have a relationship with blood uric acid,triglyceride and cholesterol,but has no significant changes with different types of flight personnel.
