Epidemiology of inflammatory bowel disease in Málaga: incidence rate and follow-up of a cohort diagnosed between 2007-2008.

BACKGROUND AND

OBJECTIVES

The incidence of inflammatory bowel disease (IBD) in Spain has been traditionally lower than in Northern European countries. Recent epidemiological studies have found that these differences are diminishing. This study estimates the incidence of IBD in Málaga (Spain), a city in Southern Spain and relates its results to those found in our neighboring countries.

MATERIAL AND

METHODS

This was a prospective study designed to collect new cases diagnosed during the period from 2007-2008 and follow up these patients. Incidence is expressed as number of patients per 100,000 population per year. The population distribution found in the European Collaborative Study was used to standardize incidence rates.

RESULTS

The gross incidence rate of IBD in Málaga is 9/105, the standardized incidence rate is 12.3/105 (9.7-15.6).

CONCLUSIONS

These data are similar to those found in our surroundings, although a higher incidence rate for Crohn's disease (CD) as compared to ulcerative colitis (UC) was found. The clinical characteristics and outcomes of our patients do not differ significantly from those described for other populations.
