“…16 23 24 27 In this study, the mean incidence for the whole period was similar for men and women although there was a higher incidence rate among women during the period 1980–84. Nevertheless, the total increase of the incidence during 1985 to 1989 was due to a higher incidence among men.…”

Aim-To evaluate the incidence of Crohn's disease in Stockholm County between 1955 and 1989. Methods-A cohort of 1936 patients with Crohn's disease was retrospectively assembled. Incidence rates and changes in disease distribution were assessed. Results-The mean increase in incidence was 15% (95% confidence intervals 12% to 18%) per five year period with a mean annual incidence rate at 4.6/10 5 during the last two decades. The mean incidence for the entire study period was similar for men and women. The mean age at diagnosis increased from 25 years in 1960-64 to 32 years in 1985-89, partly because of an increasing proportion of patients aged at least 60 years at diagnosis. The proportion of patients with colonic Crohn's disease at the time of diagnosis increased from 15% to 32% (17% diVerence; 95% confidence intervals 12% to 23%) whereas the proportion of patients with ileocaecal disease decreased from 58% to 41% (17% difference; 95% confidence intervals 10% to 24%) during the study period. Elderly patients had a higher proportion of small bowel disease and a lower proportion of ileocolonic disease compared with the younger patients. Conclusion-The incidence rate of Crohn's disease in Stockholm has stabilised at 4.6/10 5 and the proportion of elderly patients has increased during a 35 year period. Colonic Crohn's disease has increased in frequency with a reciprocal decrease in ileocaecal disease. (Gut 1997; 41: 480-486)

“…This places Israel at the same level as countries such as Norway, England, Sweden, and Wales with the highest prevalence rates ever reported [19][20][21][22][23]. A rising prevalence has been recently described for southern countries and Asia, and among migrants to the Western countries [15,16].…”

“…However, an interesting finding was the low frequency (6.78%) of familial aggregation of UC found in the Mexican population compared with a high proportion of familial aggregation of UC (13.4% to 15%) in countries from Northern Europe and the United States. 9,10 There are clinical manifestations that may act differently among the different ethnic groups. Previous studies have shown different frequencies regarding the extent of the disease.…”
