What are some BMI considerations?
Although the BMI can be a reasonable tool for interpreting a person’s weight category, in some groups, it can be less accurate1. For example:
- People with more muscle (such as athletes) have a lower proportion of body fat so a higher BMI might be considered acceptable.
- Women with the same BMI as men will typically have more body fat.
- People lose lean tissue as they age so older people have more body fat than younger people even if they have the same BMI.
- People from South Asian, Chinese and Japanese background may have more body fat at lower weights and be at greater risk of ill-health. They may need a BMI threshold of > 23 kg/m2 to be considered overweight.
- People from Pacific Island backgrounds (including Torres Strait Islander peoples and Maori) often have a higher proportion of lean body mass. They might need a higher BMI threshold to be considered overweight.
- Many Aboriginal people carry weight around the middle so even modest levels of overweight might be associated with an increased risk of Type 2 diabetes.
