Fact: A different BMI for each ethnic group needed

For a while most people have assumed that the BMI could be used for all ethnic groups. Strange to be completely honest as each ethnic group faces many physiological differences. How then could the BMI use the same calculation for all?

What is the BMI?

A few years ago the BMI which stands for  Body Mass Index came about. It was a new way of measuring body fat and through using the BMI you could very quickly determine whether your weight was healthy or unhealthy for you. How the BMI works is a little bit strange and many question its validity. In this post we explain what it does and give you a chance to use the tool yourself.

BMO is an index used measuring weight in proportion to body length. The BMI gives a estimation of the health risks associated with you body weight. BMI can be used for children and adults between the ages of 2 to 70 years if age, although a a different BMI calculator is required.

A different BMI for each ethnic group

Research conducted by scientists confirmed that there are major difference in body fat per race. 5 ethnic groups were compared and the results were surprising.

The objectives of the test were as follows:

” To study the relationship between percent body fat and body mass index (BMI) in different ethnic groups and to evaluate the validity of the BMI cut-off points for obesity.

The subjects researched were:

“Populations of American Blacks, Caucasians, Chinese, Ethiopians, Indonesians, Polynesians and Thais. ”

What was used to make comparisons?

“Averages values of BMI, percent body fat, gender and age were adapted from original papers.

And the results were:

“The relationship between percent body fat and BMI differs in the ethnic groups studied. For the same level of body fat, age and gender, American Blacks have a 1.3 kg/m2 and Polynesians a 4.5 kg/m2 lower BMI compared to Caucasians. By contrast, in Chinese, Ethiopians, Indonesians and Thais BMIs are 1.9, 4.6, 3.2 and 2.9 kg/m2 lower compared to Caucasians, respectively. Slight differences in the relationship between percent body fat and BMI of American Caucasians and European Caucasians were also found. The differences found in the body fat/BMI relationship in different ethnic groups could be due to differences in energy balance as well as to differences in body build.

This concluded that:
“The results show that the relationship between percent body fat and BMI is different among different ethnic groups. This should have public health implications for the definitions of BMI cut-off points for obesity, which would need to be population-specific.”

What this basically means is that the standard BMI calculator only works for the Caucasian race. There’s also a difference in BMI for European of American Caucasians.. The question is can you use the BMI if you’re from the Black, Asian, or any other non Caucasian group? Well, the answer is no, not really. But the researchers did provide a helpful grid which doesgive an indication of the obesity level per ethnic group.
