Another factor in the pathogenesis of Type 2 diabetes is breast-feeding.
This graph shows the prevalence of diabetes by age group and according to
whether the subjects were breast-fed during infancy or not. Overall,
breast-feeding exclusively for at least 2 months was associated with a
more than 50% reduction in the prevalence of diabetes in young adults
after other factors had been taken into account. This finding also
demonstrates that factors early in life can have a profound effect on the
risk of developing Type 2 diabetes years later.
