The Prevalence of Celiac Disease in the United States

## Objectives: The prevalence of celiac disease (cd) in the united states is unknown. we sought to estimate cd prevalence nationwide by using a nationally representative sample. ## Methods: This study included 7,798 persons aged 6 years or older who participated in the national health and nutrition examination survey 2009-2010. serum samples from all participants were tested for immunoglobulin a (iga) tissue transglutaminase antibodies and, if findings were abnormal, also for iga endomysial antibodies. information about prior diagnosis of cd and use of a gluten-free diet (gfd) was obtained by direct interview. cd was defined as having either double-positive serology (serologically diagnosed cd) or a reported diagnosis of cd by a doctor or other health-care professional and being on a gfd (reported clinical diagnosis of cd). ## Results: Cd was found in 35 participants, 29 of whom were unaware of their diagnosis. median age was 45 years (interquartile range, 23-66 years); 20 were women and 29 were non-hispanic white. the prevalence of cd in the united states was 0.71% (95% confidence interval (ci), 0.58-0.86%), with 1.01% (95% ci, 0.78-1.31%) among non-hispanic whites. in all, 55 participants reported following a gfd, which corresponded to a prevalence of 0.63% (95% ci, 0.36-1.07%). ## Conclusions: The prevalence of cd in the united states was 0.71% (1 in 141), similar to that found in several european countries. however, most cases were undiagnosed. cd was rare among minority groups but affected 1% of non-hispanic whites. most persons who were following a gfd did not have a diagnosis of cd.
