Abstract
PURPOSE
India has experienced a recent sharp increase in diabetes/pre-diabetes. We conducted a systematic-review and meta-analyses to describe the most recent prevalence and trends of pre-diabetes/diabetes in urban and rural India.
METHODS
MethodsA literature search was conducted in PubMed and Scopus databases for population-based studies describing prevalence of diabetes/pre-diabetes in urban/rural populations. Trends were analysed in rural and urban settings overall, genderwise and statewise.
RESULTS
The study reports data from 1,778,706 adults in India (69-studies), from surveys conducted from 1972-2017. Prevalence of diabetes increased in both rural and urban India from 2.4% and 3.3% in 1972 to 15.0% and 19.0% respectively in year 2015-2019. This was independently observed in both genders. Similar increasing prevalence was observed for pre-diabetes, overall and in both genders. In the latest decade (2010-2019) rural and urban prevalence was highest in states of Goa (17.4%) and Tamil Nadu (24.0%) respectively. Statewise analysis observed a wide disparity in prevalence between the North and the South of India.
CONCLUSION
Pooled estimates show a relatively high burden of diabetes and pre-diabetes in rural and urban India, with narrowed urban-rural gap. Hence, it is important to plan urgent primary and secondary prevention strategies to minimize further increase in areas with high prevalence.
