"This is the first study to evaluate how common heartburn during sleep is in the general population of the United States," said the study's author, Ronnie Fass, MD, Southern Arizona VA Health Care System and University of Arizona College of Medicine, Tucson, AZ. "We found that up to a quarter of the US population loses sleep because of nighttime heartburn, and many of these individuals have related sleep complaints and suffer from excessive daytime sleepiness."
To determine predictive factors of heartburn during sleep, researchers from Tucson, AZ, Boston, MA, Baltimore, MD, and Minneapolis, MN, distributed self-report sleep habit questionnaires to 15,314 people from nine centers across the United States.

A total of 3,806 people (24.9%) reported experiencing heartburn during sleep. The results identify a link between carbonated soft drink consumption and nighttime heartburn, a result of the carbonated soft drinks' high acidity level. The study also showed that benzodiazepines were significantly associated with heartburn during sleep but did not find a similar connection for antidepressants or calcium channel blockers, two other types of medications known to precipitate gastroesophageal reflux.
