BMI does not distinguish muscle from fat, and the WHO bands were set on European populations. For South and East Asian populations the same BMI carries more health risk, which is why several countries there use 23 and 27.5 as their own cut-offs.

NCD-RisC does not publish standard deviations. SD for countries added in 2026-10 uses the global SD. Saint Lucia is one of them, so the SD, the category shares and the percentiles above use the global spread rather than one measured here.
