OBJECTIVE: The aim was to evaluate the well-being of professional pilots using a survey that included the World Health Organization (WHO)-5 Well-Being Index.METHODS: An electronic survey was sent to pilots between June 17–August 2, 2021. Pilots self-categorized as: airline transport pilot (ATP), commercial pilot, or both. Chi-squared and Fisher’s exact tests were used to evaluate differences between variables. Logistic regression was used to estimate the odds of impaired well-being.RESULTS: A total of 639 individuals returned the survey. The majority of respondents were ATPs and a majority identified as male. The average well-being score was 68.0 out of 100 possible, with 22% of respondents meeting the threshold definition of impaired well-being. The odds of having impaired well-being were not dependent on gender. In unadjusted analysis, the odds of impaired well-being were higher for those flying as commercial pilots as compared to airline transport pilots/both. Age was also strongly associated with impaired well-being, with younger pilots having greater odds of impaired well-being as compared to older pilots. Only a little over half of the surveyed pilots agreed or strongly agreed that pilot risk of occupational exposure to COVID-19 was appropriately controlled.CONCLUSION: This survey suggests an important connection between pilot age and impaired well-being scores during the COVID-19 pandemic. Future studies targeting the well-being of younger pilots will be of interest. Additionally, measures to reduce occupational risk of COVID-19 exposure may be helpful in view of the substantial fraction of pilots expressing concern regarding that risk.Stratton E, Haddon R, Murad MH, Petterson T, Nelson M, Cowl CT.
