The standard deviation for men in Solomon Islands is 5.5. About two thirds of men have a BMI between 20.3 and 31.3; for women the middle two thirds run from 20.9 to 33.3. Compared with the global mean, men here are 1.3 points higher and women 2.3 points higher.
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. Solomon Islands is one of them, so the SD, the category shares and the percentiles above use the global spread rather than one measured here.
