Background:
The aim of this study was to investigate possible associations between educational level, occupation, and hospitalization for inflammatory bowel disease.
Methods:
A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register in order to obtain data on all first hospitalizations for Crohn's disease (CD) and ulcerative colitis (UC) in Sweden during the study period (1970-2004). Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated by educational level and occupation for men and women >or=30 years. Three cohorts were defined based on occupational titles recorded in the Swedish census data in 1970 and 1980.
Results:
Significantly decreased SIRs for CD were observed for both men and women who had an educational level of >12 years. Among men, significantly increased SIRs for CD were present in all 3 cohorts among "drivers." Male "religious, juridical, and other social-science-related workers," "textile workers," and "glass, ceramic, and tile workers," and female "clerical workers," "mechanics and iron and metalware workers," and "printers and related workers" had a significantly increased SIR for CD that was present in 1 of the 3 cohorts. For UC, male "postal and communication workers," "smelters and metal foundry workers," and "chemical process workers," and female "wood workers" had a significantly increased SIR for UC that was present in at least 1 of the 3 cohorts.
Conclusions:
Educational level and occupation seem to have a minor effect on the population's likelihood of hospitalization for CD and UC.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
