The Lancet reported that the number of people living with diabetes worldwide could double to 1.3 billion by 2050. The increase will be driven by rising obesity rates and ageing populations, with countries in North Africa, the Middle East, Latin America and the Caribbean hit the hardest. But no country is expected to see a fall in its diabetes rates over the next 30 years. The Lancet authors say the diabetes is an “unhappy and inequitable story”: by 2045 around three in four adults with diabetes will live in low and middle-income countries, where currently only 10 per cent of people living with diabetes receive guideline-based care. They said rates of diabetes in wealthy countries were also higher in minority ethnic groups.
