title: Sleep problems and psychosocial work environment among Swedish commercial pilots.
abstract: BACKGROUND
  The aim of this study was to assess relationships between sleeping problems and the psychosocial work situation based on the job-strain and iso-strain models among Swedish commercial pilots.
  
  
  METHODS
  Three hundred fifty-four pilots participated (61%), who are in 2008 responded to a questionnaire concerning sleep problems, the psychosocial work situation, personal factors, and flight length.
  
  
  RESULTS
  Low social support was associated with sleep problems for pilots. High demands were associated with sleep problems among captains and long-haul flights were associated with sleep problems among first officers. Low skill discretion was associated with less sleep problems among first officers.
  
  
  CONCLUSIONS
  Psychosocial climate at work such as low social support affects negatively sleep for both captains and for first officers. More research on what creates a best social support for pilots and cabin crew is needed. Adjusting scheduling work crew teams could increase social support at work and contribute to a better sleep quality.
