INTRODUCTION We evaluated the associations between celiac disease (CD) prevalence and regional sociodemographic variables in the United States. METHODS The outcome was CD relative prevalence, defined as number of patients with CD among those in a Medicare registry per 3-digit ZIP code. Linear regression models assessed associations between relative prevalence of CD and sociodemographic variables. RESULTS CD relative prevalence was positively correlated with median income, urban area, and proximity to a CD specialty center and negatively correlated with Black race, Latino/Hispanic ethnicity, and median social deprivation index score ( P < 0.01, all). DISCUSSION CD relative prevalence is associated with indicators of economic advantage.
