International Journal of Diabetes in Developing Countries Aims and scope Submit manuscript



Non-communicable diseases are the most serious public health threat of the twenty-first century. Diabetes is becoming a major public health issue worldwide and is associated with a slew of potentially fatal comorbidities.


Based on the available literature, our systematic review and meta-analysis aimed to understand the prevalence of diabetes mellitus in the Indian tribal community.

Materials and methods

Following PRISMA guidelines, studies reporting the prevalence of diabetes mellitus among tribes in India were retrieved by independent investigators who electronically conducted a literature search by exploiting searches conducted in PubMed, Science Direct, and Google Scholar. We estimated pooled prevalence with 95% confidence intervals using the R Studio statistical tool in a random-effects model. This review includes twenty-three studies from 2000 to 2020 conducted in all five regions of India.


The pooled prevalence rate across the twenty-three studies of 35,985 participants was 6% (95% confidence intervals [CI] = 5–7%). High heterogeneity was observed in prevalence estimates. The prevalence of diabetes mellitus in different subgroups ranged from 4% (95% CI = 0.00, 0.05%) to 10% (95% CI = 0.00, 0.19) (North, 5%; South, 5%; East, 10%; West, 4%; and Central, 7%).


As a result, concentrated efforts aimed at filling awareness gaps as well as operational research or other data gaps would aid in the prevention and control of diabetes, as well as filling these gaps in tribal areas.
