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 Iran

Share of adults with a lower BMI than each value, estimated from mean and SD
BMI	WHO band	Lower, men	Lower, women
20.0	Healthy weight	16%	12%
22.5	Healthy weight	30%	22%
25.0	Overweight	47%	36%
27.5	Overweight	65%	51%
30.0	Obese	80%	67%
32.5	Obese	90%	80%
35.0	Obese	96%	89%

Read it as: a man with BMI 30 in Iran has a higher BMI than 80% of men. Values under 1% or over 99% are shown as <1 and >99.

In plain language

The standard deviation for men in Iran is 5.5. About two thirds of men have a BMI between 19.9 and 30.9; for women the middle two thirds run from 21.1 to 33.5. Compared with the global mean, men here are 0.9 points higher and women 2.5 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. Iran is one of them, so the SD, the category shares and the percentiles above use the global spread rather than one measured here.
