Prevalence of gastroesophageal reflux disease in a general population in Taiwan.

BACKGROUND AND AIM

To evaluate the prevalence and risk factors of gastroesophageal reflux disease (GERD) in a general population in Taiwan.

METHODS

A validated symptom questionnaire, the Chinese GERD questionnaire, was utilized to determine the prevalence of GERD within a community in Taiwan. A cut-off value for GERD diagnosis was a total score ≥ 12. Additionally, demographic data, including sex, age, body mass index, and consumption of tobacco and alcohol, were recorded, and a logistic regression analysis was conducted to search the independent risk factors for the development of GERD in a general population.

RESULTS

In total, 1238 residents were recruited for this study. The monthly frequencies of heartburn, epigastric acidic discomfort, and acid regurgitation were 4.4%, 3.7%, and 2.9%, respectively. The GERD prevalence was 25% in the community. The multivariate analysis showed that female sex and age of 40-49 years and 50-59 years were independent risk factors related to the development of GERD, with odd ratios of 1.71, 3.65, and 2.41, respectively (95% confidence intervals: 1.26-2.34, 1.62-8.21, and 1.11-2.54, respectively).

CONCLUSIONS

GERD has become a common disorder in the general population in Taiwan. Female sex and age of 40-49 years and 50-59 years are risk factors for the development of GERD within a community.
