Comparison of the epidemiology of disorders of gut–brain interaction in four Latin American countries: Results of The Rome Foundation Global Epidemiology Study

Abstract

AbstractBackgroundIn Latin America, there are scarce data on the epidemiology of DGBI. The Rome Foundation Global Epidemiology Study (RFGES) Internet survey included 26 countries, four from Latin America: Argentina, Brazil, Colombia, and Mexico, with a 40.3% prevalence of Rome IV DGBI. We aimed at comparing the prevalence of DGBI and associated factors among these countries.MethodsThe frequency of DGBI by anatomical region, specific diagnoses, sex, age, diet, healthcare access, anxiety, depression, and HRQOL, were analyzed and compared.ResultsSubjects included Argentina n = 2057, Brazil = 2004, Colombia = 2007, and Mexico = 2001. The most common DGBI were bowel (35.5%), gastroduodenal (11.9%), and anorectal (10.0%). Argentina had the highest prevalence of functional diarrhea (p = 0.006) and IBS‐D; Brazil, esophageal, gastroduodenal disorders, and functional dyspepsia; Mexico functional heartburn (all <0.001). Overall, DGBI were more common in women vs. men and decreased with age. Bowel disorders were more common in the 18–39 (46%) vs. 40–64‐year (39%) groups. Diet was also different between those with DGBI vs. those without with subtle differences between countries. Subjects endorsing criteria for esophageal, gastroduodenal, and anorectal disorders from Mexico, more commonly consulted physicians for bowel symptoms vs. those from Argentina, Brazil, and Colombia. General practitioners were the most frequently consulted, by Mexicans (50.42%) and Colombians (40.80%), followed by gastroenterologists. Anxiety and depression were more common in DGBI individuals in Argentina and Brazil vs. Mexico and Colombia, and they had lower HRQOL.ConclusionsThe prevalence of upper and lower DGBI, as well as the burden of illness, psychological impact and HRQOL, differ between these Latin American countries.
