Abstract: Objective To analyze the incidence of and risk factors for white matter hyperintensity(WMH)in pilots.Methods A retrospective case-control study was performed.The subjects were 1,415 pilots ages 19 to 58 who had undergone cranial MRI examination in a hospital between September 2020 and August 2023.They were divided into two groups:the WMH group and the control group(without WMH).Univariate and multivariate logistic regression analysis were used to identify the risk factors for WMH.Results There were 219 cases in the WMH group and 1,196 cases in the control group.The total incidence of WMH was approximately 15.48％,with mild,moderate and severe cases of WMH accounting for 70.78％,24.20％,and 0.47％,respectively.Regression analysis results showed that age(OR=1.625,95％CI:1.099-2.404)and flight time(OR=1.282,95％CI:1.033-1.592)were risk factors for WMH in pilots.Conclusion The incidence of WMH in pilots was approximately 15.48％.Most of WMH were mild according to Fazekas grading.Age increase and long flight time are risk factors for WMH in pilots.
