Do DRS still use BMI?
Health professionals have been using body mass index, or BMI, to help decide whether people are overweight or underweight for more than 100 years. Researchers in population studies, doctors, personal trainers, and others use the BMI in their work.
Why do Doctor's still use BMI?
Because muscle contains more water, it conducts electricity better than fat does; thus the greater the electrical resistance, the more body fat you have. ... As a result, for most of us, the higher our BMI, the more fat we tend to carry, thus BMI is a suitable proxy for tracking weight and health of entire populations.
Why is BMI a bad tool?
Not only is BMI a poor predictor of body fatness, it is an imprecise measurement for predicting health risk. For example, in a review of patients with heart disease, BMI didn't predict mortality risk at all.
Is the BMI scale outdated?
Though it has been used for decades as the go-to measurement for health based on body size, it has been widely criticized for its oversimplification of what being healthy really means. In fact, many claim BMI is outdated and inaccurate and shouldn't be used in medical and fitness settings.
Should BMI still be used?
As a single measure, BMI is clearly not a perfect measure of health. But it's still a useful starting point for important conditions that become more likely when a person is overweight or obese.
Why don't they get rid of BMI?
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
Why is BMI not a good measure of one's body composition?
That said, BMI is not a perfect measure because it does not directly assess body fat. Muscle and bone are denser than fat, so BMI can overestimate body fat in athletes with high bone density and muscle mass or underestimate it in older people who have low bone density and muscle mass.
What are some limitations of BMI?
Although BMI can be used for most men and women, it does have some limits:
- It may overestimate body fat in athletes and others who have a muscular build.
- It may underestimate body fat in older persons and others who have lost muscle.
How accurate is the BMI scale?
BMI is not an accurate predictor of health because it does not account for body fat percentage or body fat distribution. In addition, BMI cannot accurately predict the health of different demographics and races because it was created with data from only white Europeans.
