The prevalence of intolerance to glucose was compared between young im
migrant Ethiopian Jews shortly after their arrival to Israel, a simila
r group of Ethiopians 2-3 years after their arrival to Israel, and you
ng Israeli students. A relatively high prevalence of glucose intoleran
ce was found in both Ethiopian groups, but we could not demonstrate an
y deterioration in glucose tolerance after 2-3 years of Israeli life-s
tyle in the Ethiopian groups. In spite of high blood glucose levels in
response to 75 g glucose load, when compared to Israeli students the
Ethiopians' fasting insulin levels and insulin response to 75 g of glu
cose was relatively low, suggesting a higher glucose threshold for ins
ulin secretion. However, in the Ethiopians, impaired glucose tolerance
was associated with hyperinsulinemia, suggesting that similar to some
other populations glucose intolerance is associated with insulin resi
stance.
