Objective:To provide data support for optimizing aeromedical support to transporter flying personnel by comparing and analyzing the composition and variation of the medical grounding disease spectrum of them.Methods:The health profile data of transporter flying personnel who were grounded by the assessment in Air Force Medical Center from January 1, 2003, to December 31, 2020 were collected. They were grouped by grounded year (2003—2008, 2009—2014 and 2015—2020) and by post (pilot and air combat personnel). The age at the time of grounding, flying hours and grounding disease spectrum were statistically analyzed.Results:A total of 186 transporter flying personnel were enrolled, including 135 pilots (72.58%) and 51 air combat personnel (27.42%). The median grounding age of pilots was 34.0 (31.5, 39.0) years old, and the median grounding age of air combat crew was 43.0 (41.0, 46.0) years old. The top 4 system diseases in all flight grounding personnel were neurological diseases (21.51%), mental and psychiatric disorders (16.67%), cardiovascular system diseases (13.98%) and motion system diseases (10.75%). The difference in the component ratio of grounding diseases between the pilots and air combat personnel was significant ( P=0.039), and the grounding ratio of digestive system diseases in pilots was lower than that of air combat personnel ( χ2=5.40, P=0.020). The grounding ratio of motion system diseases in 2009—2014 group was lower than that of 2003—2009 group ( χ2=6.70, P=0.010). The grounding ratios of mental and psychiatric disorders in 2009—2014 and 2015—2020 group were higher than those of 2003—2008 group, with significant differences ( χ2=8.80, 7.33, P=0.005, 0.007). There were 76 types of diseases that caused transporter flying personnel grounding, and the top 3 diseases were hypertension, vascular headaches and lumbar disc herniation. Conclusions:The neurological diseases, mental and psychiatric disorders, cardiovascular system diseases and motion system diseases contribute most to the grounding of transporter flying personnel while the neurological diseases and mental and psychiatric disorders have resulted more and more groundings. As the higher flying training strength and time endurance required, the further disease spectrum analysis, as well as the corresponding prevention and treatment should be strengthened.

Objective:To provide references for disease diagnosis, treatment and aeromedical assessment by analyzing the characteristics of neurosurgical diseases in hospitalized military flying personnel.Methods:The case data and aeromedical assessment conclusions of 56 military flying personnel admitted to the Neurosurgery Department of Air Force Medical Center from 2010 to 2020 were collected. The diagnosis and treatment, as well as the flight post and aircraft type were retrospectively analyzed against the assessment conclusions.Results:The constituent ratio descending order of the neurosurgical diseases in the flying personnel was cerebrovascular disease (35.71%), central nervous system tumors (17.86%), sellar lesions (17.86%), arachnoid cysts (16.07%), traumatic brain injury (5.36%), scalp tumors (3.57%) and syringomyelia (3.57%) respectively. Among the 20 patients with cerebrovascular diseases, 5 received surgical treatment and other 15 received conservative treatment. In which 10 cases were qualified or restricted qualified, 9 cases were temporarily grounded, and 1 case was disqualified for flight. Among the 10 cases with central nervous system tumor, 5 received surgical treatment, 1 received radiotherapy and 4 received conservative treatment. In which 3 cases were qualified or restricted qualified, 3 cases were temporarily grounded and 4 cases were disqualified for flight. Among the 10 cases with saddle area lesions, 2 received surgical treatment, 3 received medical treatment and other 5 were observed by followed up. In which 8 cases were qualified or restricted qualified, 1 was temporarily grounded and 1 was disqualified for flight. Among the 9 cases with arachnoid cysts, 1 received surgical treatment and 8 received conservative treatment. In which 5 cases were qualified or restricted qualified, 1 was temporarily grounded and 3 were disqualified for flight. Among the other 7 cases, 5 received medical treatment or observed by follow-up, and 2 received surgical treatment. In which 6 cases were qualified for flight and 1 was temporarily grounded.Conclusions:Neurosurgical diseases should be paid more for flight safety due to quite a few restricted qualified, temperedly grounding or disqualified cases existed in the military flying personnel with such diseases.
