ObjectivesPatients with rheumatoid arthritis (RA) have a high prevalence of nausea, vomiting, postprandial fullness, and abdominal pain; these are symptoms that are similar to those in gastroparesis (GP). The aim of this study was to assess the association between GP and RA and the determinants of GP.MethodsWe identified patients with RA and patients with GP from the 2012-2014 National Inpatient Sample database. The t test and the χ2 test were used for continuous and categorical variables, respectively. We determined the association between RA and GP and independent predictors of GP by multivariate analysis.ResultsOf 1,514,960 patients with RA, there were 1070 hospitalizations in which a primary diagnosis of GP was identified. The GP odds ratio in RA was found to be 1.36 and the 95% confidence interval was 1.24 to 1.49 (P < 0.0001). The variables increasing the odds of GP were age intervals of 18 to 35 years, 36 to 50 years, and 51 to 65 years; being female, White, or Black; a median household income in the 26th to 50th and the 51st to 75th percentiles; having diabetes mellitus; and having RA.ConclusionsAn increased likelihood of 36% of GP among patients with RA was determined. White and Black patients younger than age 65 showed a greater risk of developing GP.
