Diabetes mellitus (DM) is a public health problem, especially in developed countries. It affects about 9.1% of the adult population in Europe and 13.3% in the United States of America . The greater prevalence of DM in developed countries is broadly associated with ageing of the population . Between 2015 and 2030, the world population aged over 60 years is projected to increase by 56%, from 901 million to 1.4 billion; by 2050 it is expected to reach nearly 2.1 billion . These data suggest that the number of postmenopausal women with DM will grow substantially.
