Objective
To estimate the prevalence and association of work organization associated
with poor sleep quality among airline pilots.
Methods
1234 airline pilots filled out an online questionnaire. Independent
variables included demographic data, work organization aspects, health, and
sleep information. A question derived from the Karolinska Sleep
Questionnaire was used to obtain subjective sleep quality. Poisson
regression with robust variance was performed.
Results
The prevalence of poor sleep quality was 48.2%. Poor sleep quality was
associated with high frequency of technical delays, ≥ 5 consecutive
night shifts, moderate and great need for recovery after work, difficulty
commuting to work, being insufficiently physically active and sleeping 6-8
hours and < 6 hours on days off.
Conclusion
Pilots' daily work schedules, consisting of frequent delays, long working
hours and perceived high work demands preventing adequate recovery were
associated with poor sleep quality.
