Abstract
AIM: To conduct a systematic and critical review of published studies on prevalence of Type 2 diabetes mellitus (T2DM) in urban and rural areas of India. METHODS: We conducted a literature search in PubMed, EMBASE and Web of Science using the terms 'prevalence', 'Type 2 diabetes, 'India', 'urban' and 'rural' for English language articles published during January 1994-December 2018. We selected articles that reported the results of original studies that randomly sampled adults aged 15-80 years, and which reported T2DM prevalence based on the actual examination of blood samples. RESULTS: Of 1751 articles screened by titles and abstracts, 37 fulfilled our inclusion criteria. Majority (28 of 37; 76%) of studies were from South India, especially from the states of Tamil Nadu, Andhra Pradesh, Kerala and Karnataka. The prevalence of T2DM showed a wide range from 1.9% to 25.2%. Only 11 studies covering 24 regions separately reported the data by urban or rural location. Albeit inconsistent, 17 studies reported prevalence of T2DM by age group. CONCLUSION: In this systematic review, we show that there remains an ambiguity about the actual prevalence of T2DM from India due to several factors. The findings underscore a strong need for having periodic regional surveillance involving appropriate epidemiological methods.
