Large variations occur in the prevalence of diabetes in populations around
the world, ranging from less than 1% in the Bantu in Africa to as high as
50% in the Pima Indians in the USA. Within the USA, and in other
countries, there are large differences in the prevalence of diabetes among
different ethnic groups. Furthermore, even in the same ethnic group there
are marked differences in prevalence in different countries. For example
the prevalence of diabetes among the Chinese living in Mauritius is much
higher than in China.
What are the explanations for these differences?
