Summary

Pilot mortality data from 1950-1984 reveals a significantly higher risk of death from aircraft accidents. Conversely, pilots showed a lower risk of death from atherosclerotic heart disease, warranting further study.

Area of Science:

  • Occupational Health
  • Epidemiology
  • Aviation Medicine

Background:

  • Pilot occupation is associated with unique health risks.
  • Previous studies on pilot mortality have yielded varied results.
  • Understanding long-term health outcomes in pilots is crucial for occupational safety.

Purpose of the Study:

  • To investigate the mortality patterns of pilots in British Columbia.
  • To identify specific causes of death with elevated or depressed proportional mortality ratios (PMR) among pilots.
  • To explore potential associations between piloting and cancer mortality.

Main Methods:

  • Retrospective cohort study analyzing mortality data of pilots in British Columbia from 1950 to 1984.
  • Utilized proportional mortality ratios (PMR) and proportional cancer mortality ratios (PCMR) for analysis.

  • Compared observed deaths to expected deaths based on the general population.

    • Main Results:

    • A total of 341 pilot deaths were recorded during the study period.
    • Significantly elevated PMR for aircraft accidents (PMR = 3196).
    • Significantly depressed PMR for atherosclerotic heart disease (PMR = 47).
    • Elevated, though not statistically significant, PCMRs were observed for colon cancer, brain cancer, nervous system cancers, and Hodgkin's disease.

    Conclusions:

    • Pilots exhibit a markedly increased risk of mortality due to aircraft accidents.
    • Pilots demonstrate a reduced risk of mortality from atherosclerotic heart disease.
    • Preliminary findings suggest potential links between piloting and certain cancers, meriting further investigation.
    • Further epidemiological studies on commercial airline pilots are recommended to confirm these findings and explore underlying mechanisms.
