Diabetes prevalence across CARICOM ranges from 8.5% in Haiti to 16.4% in Guyana – a nearly twofold difference across a single regional bloc. The 2025 International Diabetes Federation (IDF) Diabetes Atlas provides comparable estimates for 14 CARICOM states, adjusted for age structure so that countries with younger and older populations can be compared on equal footing.

Guyana (16.4%), Belize (14.1%), St Kitts and Nevis, and Suriname (both 13.8%) record the highest rates. A broad middle band, from Barbados (13.2%) down to Grenada (11.3%), accounts for seven countries. The Bahamas (8.9%), St Vincent and the Grenadines (8.6%), and Haiti (8.5%) sit noticeably apart at the lower end.

The wider North America and Caribbean region already carries the second-highest diabetes prevalence of any world region, and the IDF projects another 12 million adults will be living with diabetes across it by 2050. For CARICOM countries already near the top of this spectrum, that trajectory sharpens what is already one of the region’s most pressing public health challenges.
