Global prevalence estimates of IGT by IDF region [9]. Data source: IDF Diabetes Atlas – 8th Edition. Percentages represent unadjusted regional prevalence estimates. Numbers in parentheses represent the estimated number of individuals affected by IGT in each region. Prevalence estimates calculated by the IDF using a generalised linear regression model. A variety of country-level data sources were included, mostly from peer-reviewed journals and national health surveys. The studies selected were required to meet rigorous inclusion criteria based on input from international experts. Prevalence in countries without original data available was extrapolated based on data collected from similar countries, based on ethnicity, income level and geography.
