Abstract

This study was conducted to identify the factors for serum cholesterol level among Korean Air Force pilots. We obtained risk factors for 408 pilots examined during period from January 1996 through March 1997. The associations between total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol and age, body mass Index(BMI), smoking, drinking, blood pressure, flight time and fat intake were analyzed. The mean serum total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride levels were 161.8+/-31.0 mg/dl, 475+/-11.0 mg/dl, 93.1+/-30.2 mg/dl, and 106.5+/-61.3 mg/dl respectively. Possible risk factors were total flight time, BMI, smoking, drinking, exercise, flight, and fighter or not. Total flight time and BMI were statistically significant factors In serum cholesterol level while controlling for the effect of the remaining factors. The longer the total flight time, the higher the level of serum total cholesterol. Total flight time, BMI, and drinking amount were statistically significant factors in serum HDL-cholesterol while controlling for the effect of the remaining factors. The higher the BIM, the lower the level of HDL-cholesterol. BMI was a statistically significant factor in seurm LDL-cholesterol while controlling for the effect of remaining factors. Total flight time, BIM, and flight were statistically significant factors in serum triglyceride while controlling for the effect of the remaining factors. Conclusively, BIM was a only significant factor in all four lipid levels, and total flight time took an affect to total cholesterol, HDL-cholesterol, and triglyceride levels.
