• Description:
  Objectives.
  
  Flight attendants perform physically demanding work such as lifting baggage, pushing service carts, and spending the workday on their feet. We examined if more frequent exposure to occupational physical demands could explain why previous studies have found that flight attendants have a higher reported prevalence of menstrual cycle irregularities than other workers.
  
  Methods.
  
  We conducted a cross-sectional analysis of 694 flight attendants and 120 teachers aged 18–44 years from three U.S. cities. Eligible participants were married, had not had a hysterectomy or tubal ligation, were not using hormonal contraception, and were not recently pregnant. Participants reported menstrual cycle characteristics (cramps, pain, irregular cycles, flow, bleed length, cycle length) and occupational physical demands (standing, lifting, pushing/pulling, bending/twisting, overall effort). We used log-binomial regression to examine associations between occupation (flight attendant, teacher) and menstrual irregularities; among flight attendants, we further examined associations between occupational physical demands and menstrual irregularities.
  
  Results.
  
  All occupational physical demands were more commonly reported by flight attendants than teachers. Flight attendants reported more frequent menstrual cramps than teachers, and most occupational physical demands were associated with more frequent or painful menstrual cramps. Lifting heavy loads was also associated with irregular cycles.
  
  Conclusions.
  
  Occupational physical demands were associated with more frequent and worse menstrual pain among flight attendants. The physical demands experienced by these workers may contribute to the high burden of menstrual irregularities reported by flight attendants compared to other occupational groups, such as teachers.
