has an estimated 77 million people with diabetes, which makes it the second most affected in the world, after China. One in six people in the world with diabetes is from India. The number is projected to grow by 2045 to become 134 million per the International Diabetes Federation. In India, type 1 diabetes is more rare than in western countries. Only about one-third of type 2 diabetics in India are overweight or obese. A 2004 study suggests that the prevalence of type 2 diabetes in Indians may be due to environmental and lifestyle changes resulting from industrialization and migration to urban environment from rural. These changes also occur earlier in life, which means chronic long-term complications are more common.
Epidemiology
In 2020, according to the International Diabetes Federation, 463 million people have diabetes in the world and 88 million people in the Southeast Asia region. Of this 88 million people, 77 million belong to India. The prevalence of diabetes in the population is 8.9%, according to the IDF. According to the IDF estimates, India has the second highest number of children with type 1 diabetes after the United States. It also contributes to the largest proportion of incident cases of type 1 diabetes in children in the SEA region. Per the World Health Organization, 2% of all deaths in India are due to diabetes. The number of people with diabetes in India has increased from 26 million in 1990 to 65 million in 2016. According to the 2019 National Diabetes and Diabetic Retinopathy Survey report released by the Ministry of Health and Family Welfare, the prevalence was found to be 11.8% in people over the age of 50. The prevalence was similar in both male and female populations. It was higher in urban areas. When surveyed for diabetic retinopathy, which threatens eyesight, 16.9% of the diabetic population aged up to 50 years were found to be affected. Per the report, diabetic retinopathy in the 60-69-years age group was 18.6%, in the 70-79-years age group it was 18.3%, and in those over 80 years of age it was 18.4%. A lower prevalence of 14.3% was observed in the 50-59-years age group. High prevalence of diabetes is reported in economically and epidemiologically advanced states such as Tamil Nadu and Kerala, where many research institutes which conduct prevalence studies are also present. The majority of diabetes cases are of type 2 diabetes. In order to control diabetes in India, the Government of India initiated the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke in 2010. It aims to set up outreach camps for opportunistic screening at all levels in the health care delivery system for early detection of diabetes, among other illnesses.
Prevention
Preventing diabetes in the developing nations is valued highly because of the high cost of treating it. In India, it is estimated that a diabetic person spends a median of for medical treatment. Pragmatic, cost-effective strategies for primary prevention of diabetes is necessary. Studies using information technology were tested. In one such program, SMS was used to motivate people with impaired glucose tolerance to follow lifestyle modification. This was found to be effective with a relative risk reduction of 36% compared to the participants who had only standard care.
Indian Diabetes Prevention Program
The Indian Diabetes Prevention Program is a three-year randomized control trial that employed LSM and metformin to prevent type 2 diabetes in subjects with IGT. It concluded that LSM and Met were cost-effective interventions for preventing diabetes among high-risk individuals in India and other developing countries.
