Abstract：Objective We intended to investigate the nutritional status of transport aviators in an Air Force Base and provide a scientific basis for guiding aviators with a reasonable diet. Methods According to the"Army Dietary Survey Methods"(GJBI636-93),weighing method was used to investigate the dietary pattern and nutritional level,and the physical examination parameters were also analyzed.Results The daily intake of total energy for each subject was 17 433 kJ,including 12%for protein,48%for fat,40%for carbohydrate.The intake of grain, vegetable oil,fruits,organs,fish and other food was insufficient,but the intake of meat and vegetables exceeded the standard.The number of overweight and obese aviators,which was assayed by body mass index,was about 37%.Physical examination results showed that 15%of the aviators had fatty liver,5%had high cholesterol,15%had high triglycerides,and 8%had hypertension,most of whom were distributed among the aviators from 45 to 55 years old. Conclusion The dietary pattern is not reasonable.It is recommended to increase the supply of grain,vegetables,milk,fruits and reduce meat and vegetable oils.It is suggested that cooking methods should be improved and balanced diets should be provided and physical exercises should be enhanced.When the aviators enhance their physical fitness and reduce the incidence of high blood pressure,hypertriglyceridemia,high cholesterol disease,combat effectiveness can also be strengthed.
