title: Burden of diabetes mellitus and prediabetes in tribal population of India: a systematic review.
abstract: OBJECTIVE
  To estimate the burden of diabetes mellitus and pre-diabetes in tribal populations of India.
  
  
  METHODS
  The authors reviewed studies from 2000 to 2011 that documented the prevalence of diabetes mellitus in various tribal populations of India. The search was performed using electronic and manual methods. Meta-analysis of data on point prevalence was performed.
  
  
  RESULTS
  A total of seven studies were retrieved. The prevalence of diabetes mellitus ranged from 0.7% to 10.1%. The final estimate of diabetes prevalence obtained after pooling of data from individual studies, was 5.9% (95% CI; 3.1-9.5%). The prevalence for impaired fasting glucose (IFG) varied from 5.1% to 13.5% and impaired glucose tolerance (IGT), from 6.6% to 12.9%.
  
  
  CONCLUSIONS
  Chronic disease research in tribal populations is limited. The reported prevalence of IFG/IGT was higher than the prevalence of diabetes and this observation could be suggestive of a potential increase in diabetes in the coming years. Given that lifestyle changes have occurred in the tribal populations, there is a need to synthesize evidence(s) relating to diabetes and other chronic diseases in these marginalized populations and inform policy makers.
