Abstract
Objective To analyze the prevalence status of pre-diabetes mellitus ( PDM ) among military flight personnel, and to provide reference for the prevention and control of diabetes mellitus (DM). Methods A total of 1 092 flight personnel were randomly selected from April 2018 to October 2018 for recuperation in two special servicemen recuperation centers by cluster sampling method. A questionnaire was designed to collect types of aircraft and personnel, age, smoking history and family history of DM. Blood pressure, height and body mass of the subjects were measured, body mass index (BMI) was calculated, fasting elbow venous blood was drawn from the subjects, and fasting plasma glucose (FPG) and 2-hour postprandial blood glucose (2 h PG) after 75 g glucose powder loading were detected. Results The prevalence of PDM was 7. 05% (77 / 1 092), and the proportion of impaired fasting glucose ( IFG), impaired glucose tolerance (IGT) and IFG + IGT were 27. 27% (21 / 77), 68. 83% (53 / 77) and 3. 90% (3 / 77), respectively. The comparison of different age groups showed that the prevalence of PDM was 3. 35% (6 / 179), 5. 98% (30 / 502), 9. 68% (27 / 279), and 11. 29% (14 / 124) in flight personnel aged 20 - 30, > 30 - 40, > 40 - 50 and > 50, respectively. There were statistically significant differences in the prevalence of PDM (P < 0. 05), FPG and 2 h PG after glucose load among all groups (P < 0. 01). With the increase of age, the prevalence of PDM, FPG and 2 h PG increased gradually. According to BMI, the flight personnel were divided into normal, overweight and obese groups. The prevalence of PDM in the three groups was 4. 35% (20 / 460), 9. 92% (50 / 554) and 11. 11% (7 / 70), respectively, and the differences were statistically significant (P < 0. 05). The prevalence of PDM, FPG and 2 h PG gradually increased with the increase of BMI. There was no significant difference in the prevalence of PDM among different types of aircraft (fighter, bomber, helicopter, transport aircraft, and unmanned aerial vehicle) and different types of personnel ( pilot, technical personnel or combat personnel) (all P > 0. 05). Compared with the pilots with normal blood glucose, PDM group was characterized by older age and higher BMI, FPG and 2 h PG after glucose load ( all P < 0. 05). There were no significant differences in DM family history, systolic blood pressure and diastolic blood pressure between the two groups (P > 0. 05). Conclusion PDM flight personnel are mainly IGT. With the increase of age and BMI, the prevalence of PDM and the levels of FPG and 2 h PG after glucose load gradually increase. For flight personnel over 40 years old or overweight or obese, glucose tolerance screening should be carried out to ensure the prevention and control of DM.
