Abstract: Objective: To investigate the prevalence and characteristics of hyperlipidemia in air force fighter pilots. Methods: Eight hundreds air force fighter pilots served as subjects. Blood lipid data were analyzed based on "Principles for the Prevention of Dyslipemia of China" in this group of subjects. Results: High prevalence of hyperlipidemia （57.00%） was found as follows: hypertriglyceridemia 23.75%; hypercholesterolimia 17.13%; low high density lipoprotein （HDL-C）10.13%;mixed type 6.00%. Conclusion: As the incidence of hyperlipidemia in air force fighter pilots is much higher than that of general population, the prevention and treatment of hyperlipidemia must be enhanced in air force flying unit.
