Symptoms of gastro‐oesophageal reflux: prevalence, severity, duration and associated factors in a Spanish population

Abstract

The prevalence of frequent gastro-oesophageal reflux symptoms in Spain is lower than that observed in other Western populations. The psychosomatic symptom score is the factor most strongly associated with gastro-oesophageal reflux symptoms. Long-term gastro-oesophageal reflux symptoms are associated with certain genetic factors (obesity, family history of gastro-oesophageal reflux symptoms), whereas short-term gastro-oesophageal reflux symptoms are associated with factors of probable environmental nature.
