They can have a high BMI because they have more muscle mass, but this does not mean they weigh too much for their height.

Another limitation of BMI is that it does not distinguish between people of different racial or ethnic groups. Studies have shown that non-Hispanic white, non-Hispanic Black, and Mexican Americans may have significantly different levels of body fat but the same BMI as people from other groups.

This inaccuracy may lead to a misdiagnosis or an incorrect assessment of risk factors between individuals. BMI can offer a rough idea of whether or not a person is at a moderate weight, and it is useful for measuring trends in population studies.

They can then divide this measurement by the width of their hip at its widest part.

The waist-to-height ratio WtHR is another tool to assess body size. According to research , higher WtHR has associations with worse cholesterol and blood pressure, even at a healthy BMI.

For this reason, WtHR may be helpful when assessing health risk when used along with other measures of health. To calculate WtHR, divide waist size by height. If the result is 0.

A study concluded that a WtHR of 0. However, this study did not account for ethnicity. For example, a 30 year old male with a 0. On average, a female of the same age and WHtR may be at risk of a 4.

Some evidence suggests that the associations between BMI, body fat percentage, and body fat distribution may differ across populations due to variations in sex, race, and ethnicity. A Brazilian study from looked at the correlation between BMI and body fat percentage in adult males and females.

They concluded that to predict obesity-type body fat percentage, the standard BMI threshold of In Korea, they added, there is evidence to suggest that almost twice as many people have features of metabolic obesity but a moderate weight compared with the United States.

The results of one study found that Asian American people within the healthy weight range were more likely to have symptoms of metabolic syndrome than their non-Hispanic white counterparts. The following table by the WHO shows some comparisons and cutoff points that may apply.
