Participation in pooled analyses
 

  • The cohort is potentially interested in participating in pooled analyses of (European) occupational cohort studies (note pooled analyses also includes remote decentralized analyses that would not require any transfer of primary data as well as meta-analyses).

Main aim of cohort, please briefly describe the main objectives of the cohort
  Evaluate the association between occupational exposure to cosmic radiation and circadian rhythm disruption and cause-specific mortality
Study design (please select as many as appropriate)
 

  • Retrospective cohort

Source population (please select as many as appropriate)
 

  • Industry / occupation-based

Comparators (please select as many as appropriate)
 

  • Internal study population
  • External study population (includes SMR/SIR studies)

Inclusion criteria
  The cohort was assembled from the personnel records of Pan Am, which are available for employees who stopped working for Pan Am in 1953 or later. Employees who were employed for at least 1 year as a flight attendant before Pan Am ceased operation in 1991, were U.S. citizens when they were hired, and who worked at least 1 day after January 1, 1953 were included in the cohort.
