RESULTS: Three thousands and nine-hundred thirty four3.934 individuals were interviewed. A prevalence of 31,3% (CI 95% 29.9%-32.8%). After allowing for confounding gastroesophageal reflux disease was significantly associated with female sex, living without partner, low level of formal education, insomnia, psychological distress, reported stressful psychosocial events in the last year, obesity and overweight.
