Ingesting poorly chewed food may delay gastric emptying and favor the development of gastroesophageal reflux disease (GERD). Objective This study investigated the association between masticatory dysfunction and GERD in the elderly from a rural area in southern Brazil. Methods This census invited all 489 elderly from a city to participate. The study used a GERD symptoms questionnaire, followed by an oral examination. Masticatory dysfunction was analyzed based on the chewing difficulty for some food groups. Tooth loss and chewing self-perception were also considered as exposure variables. Poisson regression determined the association among variables by calculating the prevalence ratio [PR(95% confidence interval)]. Results The response rate was 93.1% (n=455, average age of 70.9 years, 50.5% men). The prevalence of GERD in this population was 36.9%. GERD was associated with chewing difficulty for vegetables (PR=1.54), meats (PR=1.34), and cereals (PR=1.43) but not with poor chewing self-perception (PR=0.80) and tooth loss (PR=1.22). GERD was also associated with xerostomia (PR=1.63) and the female gender (PR=1.35). Conclusions Elderly people from a rural area with a reduced number of teeth present chewing difficulty and a high prevalence of GERD, indicating an association between GERD and masticatory dysfunction.
