Overview
Celiac Disease is more prevalent than previously thought. Prevalence has been shown to be as high as 1:250 [1] ). The prevalence may be as high as 1:133 in the general population.
Epidemiology
The prevalence of clinically diagnosed disease (symptoms prompting diagnostic testing) is 0.05–0.27% in various studies. However, population studies from parts of Europe, India, South America, Australasia and the USA (using serology and biopsy) indicate that the prevalence may be between 0.33 and 1.06% in children (5.66% in one study of Saharawi children[2]) and 0.18–1.2% in adults.[3] People of African, Japanese and Chinese descent are rarely diagnosed; this reflects a much lower prevalence of the genetic risk factors. Population studies also indicate that a large proportion of coeliacs remain undiagnosed; this is due to many clinicians being unfamiliar with the condition.[4]
A large multicentre study in the U.S. found a prevalence of 0.75% in not-at-risk groups, rising to 1.8% in symptomatic patients, 2.6% in second-degree relatives of a patient with coeliac disease and 4.5% in first-degree relatives. This profile is similar to the prevalence in Europe.[5]
