Background: There are increasing concerns regarding increased cancer risks in professional flight attendants due to their exposure to occupational hazards that are known or suspected to be carcinogenic. In this study, we aimed to analyze various cancer risks among a cohort of Korean air transportation industry workers.
Methods: We used data from the Korean National Health Insurance Service (NHIS) database from 2002 to 2015. The age-standardized incidence ratios (SIRs) for all types of cancers in the aircraft transport industry workers compared to government employees and the entire employee population were calculated with adjustment for five-year age ranges via the indirect standardized method with gender stratification.
Results: Leukemia (ICD-10; C91-C95) showed significantly higher SIRs (95% confidence interval (CI)) compared to the government employee group (1.86, 1.15-2.84) and the whole employee group (1.77, 1.10-2.70).
Conclusion: Air transportation industry workers have an increased risk of leukemia compared to other occupational groups.
