Abstract：Objective To investigate the nutritional status of pilots from different aircraft types and analyze correla-tion between nutritional metabolic indexes and body composition indexes,so as to provide rational nutrition guiding and improve their nutritional status.Methods Physical examination was carried out and body composition was measured on the pilots recuperated in author's center during July to November 2023,the blood lipids,blood glycose(BG),blood uric acid(BUA)and body composition indexes of 88 fighter pilots and 52 transport pilots were collected,and the correlation between nutritional metabolic indexes and body composition indexes was explored.Results Body mass index(BMI),skeletal muscle mass,body fat mass and visceral fat area of transport pilots were higher than those of fighter pilots(all P＜0.05).The abnormal ratio of BMI,body fat mass,fat percentage,visceral fat area of the transport pilots were signifi-cantly higher than those of the fighter pilots,while the abnormal rate of skeletal muscle mass were significantly lower than that of the fighter pilots,and the difference between the two groups was statistically significant(P＜0.05).Total cholesterol(TC)of fighter pilots was positively correlated with fat percentage(P＜0.05),BG was positively correlated with body fat mass and visceral fat area(all P＜0.05),triglyceride(TG)and BUA were positively correlated with body composition indexes(except waist to hip ratio)(all P＜0.05).TC,low-density lipoprotein cholesterol(LDL-C),BG were positively correlated with BMI,body fat mass,fat percentage,visceral fat area and waist to hip ratio(all P＜0.05),TG was positively correlated with BMI,body fat mass,fat percentage and visceral fat area(all P＜0.05);BUA was positively correlated with BMI,skeletal muscle mass,body fat mass,fat percentage and visceral fat area(all P＜0.05).Conclusion The nutritional status of pilots is dif-ferent among different aircraft types,and the nutritional metabolic index is closely related to the body composition index,the body composition analysis should be included in the physical examination in all levels of recuperation institutions,nutritionists should comprehensively analyze the nutritional metabolic index and body composition index according to the performance and task characteristics of pilots from different aircraft types,so as to provide personalized nutritional assessment and dietary guidance to change the sub-health status of pilots.
