Abstract：Objective To analyze the influencing factors of prediabetes in Chinese military flying personnel,and to provide reference for prevention and control of prediabetes and diabetes.Methods Flying personnel recuperating in two healthcare centers for special services from April to October 2018 were included as research objects.Clinical data,flight data,body measurements,and laboratory indicators were collected,and blood glucose levels were detected after taking 75 g glucose for 2 h.Logistic regression analysis and nomogram model were used to analyze the factors affecting prediabetes.Results Among the 1 092 flying personnel,77(7.05％)had prediabetes,1 007(92.22％)had normal glucose,and 8(0.73％)had diabetes.Age,flight time,proportion of drinking history,proportion of hypertriglyceridemia(HTG)history,body mass index,waist-to-hip ratio(WHR),triglyceride,total cholesterol,proportion of liver dysfunction,fasting blood glucose,and 2-hour postprandial blood glucose in prediabetes group were significantly higher than those in normal blood glucose group(P＜0.05).Alcohol consumption,liver dysfunction,WHR,flight time exceeding 2 000 h,and HTG were independent influencing factors of prediabetes.Nomogram model analysis showed that the total score of each factor ranged from 90 to 166,and the corresponding prediction probability ranged from 0.05 to 0.60.The higher the total score,the greater the risk of prediabetes.Conclusion Alcohol consumption,liver dysfunction,flight time exceeding 2 000 h,HTG,and WHR may be independent influencing factors of prediabetes in military flying personnel.The nomogram model including the above factors can more intuitively evaluate the risk of prediabetes in flying personnel and provide clues for the screening and prevention of prediabetes and diabetes.
