Columns may not sum to 100 because of rounding. Real BMI distributions have a longer right tail than a normal curve, so the obese share here is probably a few points low.

What a given BMI means in Guinea
Read it as: a man with BMI 30 in Guinea has a higher BMI than 91% of men. Values under 1% or over 99% are shown as <1 and >99.
In plain language
The standard deviation for men in Guinea is 5.5. About two thirds of men have a BMI between 17.0 and 28.0; for women the middle two thirds run from 17.3 to 29.7. Compared with the global mean, men here are 2.0 points lower and women 1.3 points lower.
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.
Questions
- What is the average BMI in Guinea?
- 22.5 for men and 23.5 for women, with standard deviations of 5.5 and 6.2. Averaged across the sexes that is 23.0, against a global figure of 24.6.
- What share of adults in Guinea are overweight or obese?
- Our estimate from the mean and SD: 32% of men have a BMI of 25 or more, and 9% are at 30 or more. For women it is 40% and 15%. These assume a normal curve, so the true obesity shares are likely a few points higher.
- Is a BMI of 25 high in Guinea?
- A BMI of 25 is the WHO line between healthy weight and overweight. In Guinea it is higher than about 68% of men and 60% of women. For men here that is above the median, so it reads as slimmer than most.
- How does Guinea compare with Mali?
- Men in Mali average 23.0 against 22.5 in Guinea; women 23.2 against 23.5. Mali ranks 160th, Guinea 161st.
NCD-RisC does not publish standard deviations. SD for countries added in 2026-10 uses the global SD. Guinea is one of them, so the SD, the category shares and the percentiles above use the global spread rather than one measured here.
