The global prevalence of diabetes is set to double over the next 25 years. Developing countries like India, already top of the diabetes league, are expected to shoulder much of this burden. Epidemiological studies show that the prevalence of diabetes is particularly high in urban areas in India. Cities are also home to a large pool of people with a great risk of developing diabetes in the future. Several reports of migrant Asian Indians living in different parts of the world showed that these populations had a higher prevalence of diabetes than other ethnic groups living in the same countries. Changes in environmental factors, such as increased affluence, were thought to be responsible for this.
