Abstract
Background & aims: There are few data on the prevalence of gastroesophageal reflux disease (GERD) in the United States. We performed a population-based study to determine the prevalence of GERD symptoms and persistent GERD symptoms despite use of proton pump inhibitors (PPIs).
Methods: We conducted the National Gastrointestinal Survey in 2015 using MyGiHealth, an app that guides participants through National Institutes of Health gastrointestinal Patient-Reported Outcomes Measurement Information System surveys. Primary outcomes were prevalence of GERD symptoms in the past and persistence of GERD symptoms (heartburn or regurgitation 2 or more days in past week) among participants taking PPIs. Population weights were applied to the data and multivariable regression was used to adjust for confounding.
Results: Among 71,812 participants, 32,878 (44.1%) reported having had GERD symptoms in the past and 23,039 (30.9%) reported having GERD symptoms in the past week. We also found that 35.1% of those who had experienced GERD symptoms were currently on therapy (55.2% on PPIs, 24.3% on histamine-2 receptor blockers, and 24.4% on antacids). Among 3229 participants taking daily PPIs, 54.1% had persistent GERD symptoms. Younger individuals, women, Latino individuals, and participants with irritable bowel syndrome or Crohn's disease were more likely to have continued symptoms, even when taking PPIs.
Conclusions: Using a population-based survey, we found GERD symptoms to be common: 2 of 5 participants have had GERD symptoms in the past and 1 of 3 had symptoms in the past week. We also found that half of PPI users have persistent symptoms. Given the significant effect of GERD on quality of life, further research and development of new therapies are needed for patients with PPI-refractory GERD symptoms.
