Methods Weighing method was used to investigate the average daily energy of each pilots and calculate the intake of various nutrients, height and weight were measured, also blood biochemical indicators were calculated, such as body mass index (BMI), fasting blood glucose, triglyceride, total cholesterol, uric acid, etc. Results The daily intake of total energy for each pilot was 3623.9 kcal, including 15.8% for protein, 37.5% for fat, 46.7% for carbohydrate. The intake of cereal, beans, vegetables, fruits, eggs, milk was insufficient, the homonemeae and viscera was absent, but the intake of vegetable oil, meat and fish exceeded the standard. The intake of vitamin B2 per person was deficiency. Physical examination results showed that 116 (14.97%) of the aviators had simple triglycerides, 74 (9.55%) had simple cholesterol, 37 (4.77%) had higher cholesterol and triglycerides, 82 (10.58%) had hypeluricemia, 126 (16.26%) had fatty liver, 10 (1.29%) had impaired fasting plasma glucose, 187 had body mass index (BMI)≥26 kg/m2, 24.13% (187/775) was the detection rate, 35(4.52%) obese aviators were contained. Conclusion The dietary pattern is unbalance for these aviators in our department, some certain nutrients are too much and some nutrients are lacking . Measures should be taken to reduce fat intake, increase vegetables, fruits and viscera, aquatic products, and increase vitamin intake.
