Is BMI an Accurate Measure of Health?

In summary, the article discusses how the BMI is not always an accurate measure of health, as close to half of those considered overweight are actually healthy and about 30% of those with a normal BMI are unhealthy. It is argued that BMI should only be used as a tool by physicians and not by employers or insurance companies, as it has limitations. Additionally, the article mentions that the health risks associated with obesity and overweight are not immediate, but rather occur later in life. It is suggested that the study did not take age into account, as younger individuals are generally healthier, and only looked at the overall population rather than a specific age group.

I saw this article this morning:
http://www.sciencedaily.com/releases/2016/02/160204042240.htm

According to the article close to half of the people considered "overweight" by the BMI are in fact healthy by other more rigorous metrics, and about 30% of those with a "normal" BMI are unhealthy.

I would argue that like any other metric, BMI can be used as a tool by physicians to evaluate health, but that's because physicians are generally aware of it's limitations. The danger comes in when employers and insurance companies start applying it blindly.

The health issue of obesity and overweight as it is usually posed is that these people are at more risk of developing metabolic syndrome or cardiovascular disease later on in life not that they have it. If you are young enough you are usually healthy. Smoker are healthy until they develop lung cancer or COPD.

There is no reference to age so It seems they studied the whole population not the part (>60 yrs) that is more likely to manifest a disease process.

Related to Is BMI an Accurate Measure of Health?

1. What is BMI?

BMI stands for Body Mass Index. It is a measure of body fat based on height and weight that applies to adult men and women.

2. How is BMI calculated?

BMI is calculated by dividing a person's weight in kilograms by their height in meters squared.

3. Is BMI an accurate measure of health?

No, BMI is not an accurate measure of health. It does not take into account factors such as muscle mass, body composition, or overall fitness level.

4. What are the limitations of using BMI as a measure of health?

BMI does not differentiate between fat mass and muscle mass, which can lead to inaccuracies in individuals who have a high muscle mass. It also does not consider where fat is stored in the body, as fat stored around the waist can be more harmful to health than fat stored in other areas.

5. Are there better alternatives to using BMI?

Yes, there are alternative measures of health such as waist circumference, body fat percentage, and waist-to-hip ratio that may provide a more accurate assessment of health. It is important to consult with a healthcare professional for an individualized evaluation.
