Does month of birth affect risk of Crohn's disease in childhood and adolescence?

摘要

Early factors seem to have a role in the development of Crohn's disease later in life. A few recent studies have shown that in utero or early infections-in particular measles-are important risk factors, but other studies have failed to show an association. A recent British study reported slightly increased risk of Crohn's disease in people born in the first half of the year. If infectious agents potentially linked to Crohn's disease include some that are common at particular times of year, their seasonal variation might be reflected in the pattern of birth month in people with Crohn's disease.
