The prevalence of diabetes and impaired glucose tolerance in women of childbearing age is increasing worldwide, particularly among minority youth. As a consequence, in many parts of the world the number of pregnancies complicated by Type 2 diabetes is actually exceeding those complicated by Type 1 diabetes. Moreover, also the prevalence and incidence of gestational diabetes mellitus have been rising over recent years.
