Job Security Study: Lots of People Have Reflux Symptoms & COVID-19 Due To Singing

A recent study (SD Delshad, CV Almario et al. Gastroenterol 2020; 158: 1250-61) used survey data from an APP, MyGiHealth, to assess prevalence of reflux symptoms and symptoms that had not responded to proton pump inhibitor treatment.

Key findings:

  • In 2015, among 71,812 participants, 32,878 (44.1%) reported reflux symptoms previously and 23,039 (30.9%) reported reflux symptoms in previous week
  • 35% with reflux symptoms were currently receiving treatment: 55% PPIs, 24% H2RAs, and 24% antacids
  • Of the 3229 taking daily PPIs, 54% reported persistent reflux symptoms (≥2 days per week)
  • Age range of respondents was 33% for 18-29, 27% for 30-39, 17% for 40-49, 15% for 50-59, and 8% ≥60


  • Potential selection bias as there was only a 5.5% response rate among the entire eligible population of 1.3 million
  • Reflux symptoms frequently is not due to reflux disease

My take: There are a lot of folks with reflux symptoms and many have ongoing symptoms despite treatment; hence, lots of opportunity to help (and job security)
