On both univariate and multivariate analysis, age > 50 years old (OR = 6.33; 95% CI 1.1-35.6), handwashing habit before eating (OR = 6.93; 95% CI 1.1-43.8), and raw/tap water (OR = 10.28; 95% CI 0.8-130) were significantly associated with the presence of GERD.Conclusion: Prevalence of GERD was high (13.3%) in rural area in Jakarta.
