  • * Any gastro-oesophageal reflux symptoms (GORS): minor or severe complaints with heartburn or acid regurgitation; severe GORS: severe complaints with heartburn or acid regurgitation.

  • Relative change in prevalence = (prevalence HUNT 3/Mini-Q—prevalence HUNT 2)/prevalence HUNT 2.

  • Seven participants in HUNT 3/Mini-Q had missing information on sex.

  • § Age at time of GORS assessment (HUNT 2 and HUNT 3/Mini-Q, respectively).
