Population studies in Israel have shown that Jews born in Europe or America have the highest prevalence of juvenile diabetes mellitus and Jews born in Asia or Africa, the lowest. The rate in the Israel born, regardless of the father's place of birth, is intermediate between those of the other two groups. The rates for the group from Europe/American and for the Israel-born group increased during the years 1963-68, while that for the Asia/Africa group did not change. It is speculated that the differences in the rates of juvenile diabetes mellitus are related to different frequencies of certain HLA antigens in the different groups or to different associations with susceptibility genes to juvenile diabetes.
以色列的人口研究表明，在欧洲或美洲出生的犹太人患青少年糖尿病的比例最高，而在亚洲或非洲出生的犹太人比例最低。在以色列出生的人，无论其父亲的出生地在哪里，患病率介于其他两组之间。1963年至1968年间，欧洲/美洲组和在以色列出生组的患病率有所上升，而亚洲/非洲组的患病率则没有变化。据推测，青少年糖尿病患病率的差异与不同组中某些HLA抗原的不同频率有关，或者与青少年糖尿病易感基因的不同关联有关。
