title: Inflammatory bowel diseases: a disease (s) of modern times? Is incidence still increasing?
abstract: Inflammatory bowel diseases (IBD) are a heterogeneous group of diseases, not always easy to diagnose, even more difficult to classify, and diagnostic criteria are not always uniform. Well done population-based studies are not abundant, and so comparisons among different geographical areas or populations are not always very reliable. In this article, we have reviewed epidemiological studies available on the world's population while making a critical review of published data.
