Regional and National Variations in Reasons for Gluten Avoidance

Background: Although studies have assessed the prevalence of celiac disease (CD), less is known about the prevalence of gluten avoidance because of nonceliac gluten sensitivity (GS). The avoidance of foods other than gluten is also understudied in these 2 groups. Methods: Participants visiting a web site for information about a newly developed portable gluten detection device (Nima) were instructed to complete questions about food and gluten avoidance patterns. We assessed the relative proportion of CD and GS across world regions and United States (US) regions and determined the distribution of food avoidance patterns. Results: CD was reported in 6474 respondents and GS in 2597 respondents. Within the United States, the majority of avoiders of gluten reported having CD (69.8%), with the highest ratio of CD to GS in the Northeast (CD: 74.3%; GS: 25.7%) and the lowest in the West (CD: 67.1%; GS: 32.9%) (P
