Diabetes report 2000 — 2045

Estimates were made for 48 Sub-Saharan African countries and territories in the IDF Africa (AFR) Region. For this edition of the IDF Diabetes Atlas, a total of 25 data sources (from 20 countries) were selected. About half (58%) of the countries in the IDF AFR Region lack high-quality in-country data sources. Only one country (Zambia) had studies conducted within the past five years.

Despite the lowest prevalence estimate of 4.5% among IDF Regions, the expected increase in the number of people with diabetes by 2045 is the highest 129% reaching 55 million. The AFR Region is also predicted to have the highest increase of 107% in the number of people with impaired glucose tolerance by 2045 reaching 117 million. The proportion of undiagnosed diabetes is also highest in the AFR Region with 53.6%. Only 12.6 billion USD was spent on diabetes in AFR Region, representing 1.3% of the total spent worldwide, despite the region being home to 4.5% of people with diabetes worldwide.
