Familial incidence linked to risk for IBD in first-degree relatives

Individuals who have a sibling with inflammatory bowel disease had a fourfold-increased risk for IBD compared with the general population, according to research published in Alimentary Pharmacology & Therapeutics.
“A family history of IBD is a proxy for an individual’s genetic and, in part, environmental risk of developing the disease and has long been recognized as the strongest risk factor for IBD. ... From an etiological point of view, studies of familial aggregation of IBD may shed light on the impact of genetic and environmental risk factors,” Jonas F. Halfvarson,
