Background And Aim:
The purpose of this study was to estimate the sex- and age-specific incidence rates of inflammatory bowel diseases (IBD) in Taiwan. Site-specific cancer occurred in patients with IBD would be reported, too.
Methods:
A retrospective study by analyzing the data from the National Health Insurance Research Database of Taiwan.
Results:
Between 2000 and 2010, the overall incidence rate of Crohn's disease (CD) and ulcerative colitis (UC) was 0.208 and 0.838 per 100,000 person-years. For male, the incidence rate of CD was 0.195 (95 % CI 0.113-0.276) per 100,000 persons in 2000 and increased to 0.318 (95 % CI 0.216-0.421) per 100,000 persons in 2010. For female, the incidence rate of CD was 0.092 (95 % CI 0.035-0.149) per 100,000 persons in 2000 and increased to 0.210 (95 % CI 0.128-0.293) per 100,000 persons in 2010. For male, the incidence rate of UC was 0.690 (95 % CI 0.537-0.843) per 100,000 persons in 2000 and increased to 1.351 (95 % CI, 1.140-1.562) per 100,000 persons in 2010. For female, the incidence rate of UC was 0.386 (95 % CI 0.269-0.503) per 100,000 persons in 2000 and increased to 0.858 (95 % CI 0.691-1.024) per 100,000 persons in 2010. Among the CD patients, 0.19 % had colorectal cancers (1/519). Among the UC patients, 0.24 % had colorectal cancers (5/2098).
Conclusions:
This nationwide population-based longitudinal epidemiological study of IBD in Taiwan provides data for future global comparisons.
