Abstract

BACKGROUND:

Gastroesophageal reflux disease (GERD) is a common condition, with wide geographical differences worldwide. There are no epidemiological data on this disease for Uruguay.

OBJECTIVE:

To estimate the prevalence of GERD in two adult populations in Uruguay (urban and hospital) through the Gastroesophageal reflux disease Questionnaire (GerdQ) questionnaire and evaluation of typical symptoms.

MATERIAL AND METHOD:

A descriptive, cross-sectional study was carried out through the use of two diagnostic methods administered in two settings: an urban and a hospital setting. The first method consisted of administration of the standardized GerdQ structured questionnaire and the other consisted of evaluating the typical symptoms of GERD. A total of 1141 persons from the urban population, with a mean age of 52 years (± 18 years), and 163 persons from a gastroenterology polyclinic, with a mean age of 53 years (± 16 years), were included.

RESULTS:

The prevalence of GERD in Uruguay was 4.69%, (95% CI 2.92-6.46%) when the GerdQ questionnaire was used, but increased to 14.14% (95% CI 12.57-15.71) when only typical symptoms were considered. In the hospital sample, the prevalence was 11.66% (95% CI 6.42-16.89%) and 20.25% (95% CI 14.01-26.48), respectively.

CONCLUSION:

The prevalence obtained in the urban population of Uruguay with the GerdQ questionnaire in the symptomatic (hospital) population was more than double that in the general population, 11.66% and 4.69%, respectively. Evaluation of symptoms, pyrosis and/or regurgitation systematically yields a higher prevalence. Consensus on the definition of GERD and on the instrument used for its diagnosis are essential to interpret and compare epidemiological studies.
