Several epidemiologic studies of Crohn's Disease (CD) from the northern hemisphere show high rates of the disease among Jews. Israel has absorbed many Jews from those countries and the rates of CD in Israel are lower than in their place of birth. Important, too, among immigrants from the middle east Mediterranean countries, the rates appear to be higher than those in their countries of origin, where the disease is rare. CD has a genetic predisposition, but we physicians cannot ignore the environmental factors.
来自北半球的几项克罗恩病（CD）流行病学研究表明，犹太人中该病发病率很高。以色列吸纳了许多来自这些国家的犹太人，而以色列的CD发病率低于他们的出生地。同样重要的是，在来自中东地中海国家的移民中，发病率似乎高于他们疾病罕见的原籍国。CD有遗传易感性，但我们医生不能忽视环境因素。
