Low incidence of childhood celiac disease in the Netherlands

Abstract

The incidence and prevalence of celiac disease vary internationally. We studied the incidence of identified cases of childhood celiac disease in six Dutch provinces that cover 47.9% of the surface area and 67.6% of the total population of The Netherlands. Children with celiac disease aged 0-14 y, diagnosed from January 1975 to January 1991, were traced by 1) contacting all pediatricians in this area, 2) examining the data of the Dutch National Medical Registration, and 3) investigating the membership records of the Dutch Celiac Disease Society. These data were cross-checked by the Dutch Network and National Database of Pathology. Of the 97.9% of pediatricians who answered our inquiry, 46.1% were treating celiac patients. A total of 342 celiac patients were identified. Informed consent that permitted examination of their medical files was given by 97.3 of the parents of the celiac children. The mean crude inciden rate of diagnosed childhood celiac disease, calculated per 10 live births per year, was 0.18. However, a significant increase reported incidence was demonstrated from 0.10 in 1976 to 0. in 1990. The best estimate, for the years 1985-1990, is 0.22/10 live births, which is much lower than in most European con tries. © 1995 International Pediatric Research Foundation, Inc.
