title: [Effect of flying burthen on blood lipid in civil aviation aircrew].
abstract: OBJECTIVE
  To investigate the effect of flying burthen on blood lipid level in civil aviation flight personnel.
  
  
  METHODS
  The level of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) were determined by kits. The relationship between the blood lipid levels and the flight personnel's flying hours, body weight index, smoking, drinking and sport were investigated.
  
  
  RESULTS
  The average annual flying hours of hyperlipidemia group [(561.14 +/- 234.90) h] was significantly higher than that of non-hyperlipidemia group [(500.62 +/- 243.65) h] (P < 0.05). The level of TG of the average annual flying hours more 800 h [(1.61 +/- 0.10) mmol/L] were significantly higher than that of less than 400 h group [(1.31 +/- 0.65) mmol/L]. The morbidity rate of hyperlipidemia among the age 30 to 39 years old flight personnel was the highest.
  
  
  CONCLUSIONS
  The average annual flying hours is one of primary factors affecting blood lipid in flight personnel.
