“…Studies from the past 15 years in northern European populations have reported Crohn's disease incidence rates of 3.6-9.8/100,000 (11,12,21,22,(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37). Estimates from southern Europe range from 0.3 to 3.0/100,000 (38)(39)(40)(41)(42)(43)(44)(45). Few population-based incidence data are available from North America.…”

The aim of this study was to assess the accuracy and utility of administrative health data in identifying persons with inflammatory bowel disease on a population basis and to determine the incidence and prevalence of this disease in the Canadian province of Manitoba. The data from Manitoba Health (the province's single insurer) were used to identify residents with physician and/or hospital contacts for Crohn's disease or ulcerative colitis based on International Classification of Diseases, Ninth Revision, Clinical Modification, codes between 1984 and 1995. Of 5,182 eligible individuals, 4,514 were mailed questionnaires and 2,725 responded. Cases were defined as individuals with five or more separate medical contacts with one of these diagnoses or three or more such contacts if they were resident for less than 2 years. The accuracy of the study case definitions was high when compared with either self-report or chart review. The 1989-1994 age- and sex-adjusted annual incidence was 14.6/100,000 for Crohn's disease and 14.3/100,000 for ulcerative colitis. The prevalence of Crohn's disease in 1994 was 198.5/100,000, and that of ulcerative colitis was 169.7/100,000. In conclusion, the authors have successfully established and validated a population-based database of inflammatory bowel disease based on administrative data. The high incidence rates and dynamic epidemiology of inflammatory bowel disease in Manitoba indicate the presence of important environmental risk factors, which warrants further investigation.

Epidemiological Characteristics of Inflammatory Bowel Disease in Bologna, Italy – Incidence and Risk Factors

et al. 1993

Recently, in Bologna, an inflammatory bowel disease incidence of 7.7/10⁵/year has been calculated, about one third of that reported in Northern Europe, confirming the existence of a ‘North-South gradient’. A first peak of incidence was observed at 20-29 years of age and a second peak at 60-69 years of age for ulcerative colitis (UC) alone. A prevalence of UC males, mainly after the 7th decade, and of Crohn’s disease (CD) females in the first peak was found. A greater frequency of ex-smokers in UC, with a relative risk (RR) significantly higher in males for all age groups (RR = 6.1; p < 0.01) and of smokers in CD with a RR significantly higher in 20- to 29-year-old females (RR = 11.6; p < 0.05) was observed. A different pattern for the two diseases exists: male ex-smokers and young female smokers are at risk of developing UC and CD, respectively.

“…The studies conducted on the incidence of IBD in Spain are summarized in Supplementary Table 1. 17,19–45 Most of these studies were carried out more than a decade ago in selected areas and included a small number of patients. Differences in IBD incidence between regions have been reported, with variability between urban and rural centers and between inland and coastal areas even within a single region.…”

Background: Inflammatory bowel disease (IBD) is associated with a considerable burden to the patient and society. However, current data on IBD incidence and burden are limited because of the paucity of nationwide epidemiological studies, heterogeneous designs, and a low number of participating centers and sample size. The EpidemIBD study is a large-scale investigation to provide an accurate assessment of the incidence of IBD in Spain, as well as treatment patterns and outcomes. Methods: This multicenter, population-based incidence cohort study included patients aged >18 years with IBD (Crohn’s disease, ulcerative colitis, or unclassified IBD) diagnosed during 2017 in 108 hospitals in Spain, covering 50% of the Spanish population. Each participating patient will attend 10 clinic visits during 5 years of follow up. Demographic data, IBD characteristics and family history, complications, treatments, surgeries, and hospital admissions will be recorded. Results: The EpidemIBD study is the first large-scale nationwide study to investigate the incidence of IBD in Spain. Enrollment is now completed and 3627 patients are currently being followed up. Conclusions: The study has been designed to overcome many of the limitations of previous European studies into IBD incidence by prospectively recruiting a large number of patients from all regions of Spain. In addition to epidemiological information about the burden of IBD, the 5-year follow-up period will also provide information on treatment patterns, and the natural history and financial burden of IBD.
