Insights
The incidence of pediatric Crohn's disease more than doubled between 1983 and 1993, while pediatric ulcerative colitis rates remained stable. This study tracked inflammatory bowel disease trends in children over an 11-year period.
Area of Science:
- Pediatric Gastroenterology
- Epidemiology
- Inflammatory Bowel Disease (IBD)
Background:
- Inflammatory bowel disease (IBD) affects children and adolescents, with rising incidence in some regions.
- Understanding trends in pediatric IBD is crucial for public health planning and resource allocation.
Purpose of the Study:
- To determine the incidence and prevalence of pediatric inflammatory bowel disease (IBD) in South Glamorgan over an 11-year period.
- To analyze trends in Crohn's disease and ulcerative colitis incidence and prevalence in a pediatric population.
Main Methods:
- Retrospective study design.
- Data collection on pediatric IBD cases in South Glamorgan from 1983 to 1993.
- Calculation of incidence and prevalence rates per 100,000 child population.
Main Results:
- The incidence of pediatric Crohn's disease significantly increased, more than doubling from 1.30 to 3.11 cases per 100,000 child population per year between 1983-1988 and 1989-1993.
- The incidence of pediatric ulcerative colitis remained constant at 0.71 cases per 100,000 child population per year throughout the study period.
- In 1993, the prevalence of pediatric Crohn's disease was 16.6 per 100,000, and ulcerative colitis was 3.42 per 100,000.
Conclusions:
- A notable increase in pediatric Crohn's disease incidence occurred in South Glamorgan during the study period.
- Pediatric ulcerative colitis incidence remained stable, suggesting different etiological factors or trends compared to Crohn's disease.
- These findings highlight the importance of monitoring pediatric IBD trends and investigating potential contributing factors.
Abstract:
A retrospective study of the incidence and prevalence of paediatric inflammatory bowel disease over an 11 year period was undertaken in South Glamorgan. Over this time the incidence of Crohn's disease more than doubled from 1.30 cases per 100,000 childhood population per year in the period 1983-1988, to 3.11 cases per 100,000 population per year in the period 1989-1993. In contrast, the incidence of ulcerative colitis remained the same throughout the study period at 0.71 per 100,000 per year. In 1993 the prevalence of Crohn's disease in the childhood population was 16.6 per 100,000 and of ulcerative colitis, 3.42 per 100,000.
