Introduction : Gastroesophageal reflux disease (GERD), which leads to acid reflux into the esophagus, is a common gastrointestinal disorder. Several studies have shown the prevalence of GERD in Iranian population, but their evidence is contradictory. Therefore, the present study was conducted to investigate the epidemiology of GERD in Iran.
Methods: The entire steps of this systematic review and meta-analysis were based on the MOOSE protocol, and the results were accordance with the PRISMA guideline. To find potentially relevant published articles, comprehensive search was done on international online databases Scopus, Science Direct, EMBASE, PubMed/Medline, CINAHL, EBSCO, Cochrane Library (Cochrane Database of Systematic Reviews - CDSR), Web of Science (ISI) and Iranian online databases IranDoc, (SID), Magiran, RICST, Iranian National Library, and Barakat Knowledge Network System and the Google Scholar search engine in June 2019. Cochran test and I 2 index were used to assess the heterogeneity of the studies. Data were analyzed using Comprehensive Meta-Analysis (CMA) software.
Results: The daily, weekly, monthly, and overall prevalence of GERD symptoms in Iranian population was 5.64% (95%CI [confidence interval]: 3.77%-8.35%; N=66,398), 12.50% (95%CI: 9.63%-16.08%; N=110,388), 18.62% (95%CI: 12.90%-26.12%; N= 70,749) and 43.07% (95%CI: 35.00%-51.53%; N=73,189), respectively. The daily, weekly, monthly, and overall prevalence of heartburn in Iranian population was 2.46% (95%CI: 0.93%-6.39%; N=18,774), 9.52% (95%CI: 6.16%-14.41%; N=54,125), 8.19% (95%CI: 2.42%-24.30%; N=19,363) and 23.20% (95%CI: 13.56%-36.79%; N=26,543), respectively. The daily, weekly, monthly, and overall prevalence of regurgitation in Iranian population was 4.00% (95%CI: 1.88%-8.32%; N=18,774), 9.79% (95%CI: 5.99%-15.60%; N=41,140), 13.76% (95%CI: 6.18%-44.31%; N=19,363) and 36.53% (95%CI: 19.30%-58.08%; N=21,174), respectively.
Conclusion: The present meta-analysis provides comprehensive and useful information on the epidemiology of GERD in Iran for policy-makers and health care providers. This study showed a high prevalence of GERD in Iran. Therefore, effective measures on GERD-related factors such as lifestyle can be among the health policies of Iran.
