Incidence of juvenile-onset Crohn's disease in Scotland: association with northern latitude and affluence
View abstract on PubMed
Summary
This summary is machine-generated.Juvenile-onset Crohn's disease incidence is higher in northern Scotland and more affluent areas. Ulcerative colitis showed no such geographic or socioeconomic disparities in children.
Area Of Science
- Pediatric Gastroenterology
- Epidemiology
- Public Health
Background
- Crohn's disease incidence in Scottish children has risen over three decades.
- Previous research explored genetic factors and childhood events.
- Sociodemographic and geographic factors in juvenile-onset Crohn's disease require further investigation.
Purpose Of The Study
- To examine the sociodemographic and geographic distribution of juvenile-onset Crohn's disease in Scotland.
- To identify potential environmental or societal influences on disease patterns.
- To differentiate disease distribution from ulcerative colitis.
Main Methods
- Utilized a validated database of 580 pediatric inflammatory bowel disease cases (1981-1995).
- Classified cases by postcode for geographic location and material deprivation.
- Employed multifactorial Poisson regression to analyze effects of sex, geography, time, and deprivation.
Main Results
- Juvenile-onset Crohn's disease incidence was 2.3/100,000/year (1981-1995).
- Incidence was significantly higher in northern Scotland (3.1) versus southern Scotland (2.1).
- Children from more affluent areas (deprivation score 1) had a higher relative risk of Crohn's disease compared to less affluent areas (P=0.033).
- Juvenile-onset ulcerative colitis showed no north-south variation or association with affluence.
Conclusions
- Juvenile-onset Crohn's disease demonstrates distinct geographic and socioeconomic patterns in Scotland.
- Higher incidence in northern Scotland and more affluent areas suggests environmental or societal influences.
- Juvenile-onset ulcerative colitis incidence is not similarly influenced by these factors.
