(HealthDay News) — Airline pilots and cabin crew have an increased incidence of melanoma, according to a meta-analysis published online September 3 in JAMA Dermatology.

Martina Sanlorenzo, MD, from the University of California in San Francisco, and colleagues examined the risk of melanoma in pilots and airline crew in a meta-analysis. Nineteen studies, with more than 266,431 participants, were included, all of which reported a standardized incidence ratio (SIR), standardized mortality ratio (SMR), or data that could be used to calculate the SIR or SMR in any flight-based occupation.

The researchers found that the overall SIR was 2.21 (95% confidence interval [CI], 1.76–2.77) for participants in any flight-based occupation. For pilots and cabin crew, the summary SIR was 2.22 (95% CI, 1.67–2.93) and 2.09 (95% CI, 1.67–2.62), respectively. For participants in any flight-based occupation, the SMR was 1.42 (95% CI, 0.89–2.26). The summary SMR was 1.83 (95% CI, 1.27–2.63) for pilots and 0.90 (95% CI, 0.80–1.01) for cabin crew.

“Pilots and cabin crew have approximately twice the incidence of melanoma compared with the general population,” the authors write. “Further research on mechanisms and optimal occupational protection is needed.”
