Frequent flying, especially long-distance, is linked to more intestinal issues for flight crews. This may be due to time-shift effects impacting gastrointestinal health.

Area of Science:

  • Occupational Health
  • Gastroenterology
  • Aerospace Medicine

Background:

  • Flight crew members experience unique occupational stressors.
  • Intestinal and extraintestinal symptoms are common health complaints.

Purpose of the Study:

  • To investigate the prevalence of gastrointestinal symptoms in flight crew members.
  • To correlate symptom occurrence with flight schedules and lifestyle factors.
  • To compare symptom rates between flight and ground staff.

Main Methods:

  • Symptom questionnaire administered to 190 flight crew members and 100 ground staff.
  • Analysis of flight schedules over one month.
  • Assessment of health behaviors, job, and life satisfaction.

Main Results:

  • Flight crew reported significantly more dyspeptic symptoms than ground staff.
  • Long-distance flying was associated with increased upper gastrointestinal complaints.
  • Cabin crew reported more intestinal symptoms than cockpit members.
  • Increased symptom frequency correlated with more doctor visits, sick days, and decreased life satisfaction.

Conclusions:

  • Frequent long-distance flying may increase intestinal symptoms, potentially due to circadian rhythm disruption (time-shift).
  • Dietary habits and job satisfaction are factors influencing symptom experience in flight crews.
