BMI is measured by dividing an individual’s weight in kilograms by the square of height in meters. It does not measure body fat directly. According to the U.S. Centers for Disease Control and Prevention (CDC), a BMI between 18.5 and 24.9 among adults aged 20 and above is seen as “healthy.” BMI between 25 and 29.9 is seen as “overweight” while a value of 30 and above is classified as “obese.” In a June 14 press release, the AMA said that BMI as a measurement tool was “racist” as it has largely relied on data collected from generations of non-Hispanic white populations.

The organization said that the relative body shape and composition of human beings differ across racial and ethnic groups, genders, sexes, and ages. These factors are “essential” when applying BMI. The AMA warned that BMI must not be used as a “sole criterion” to deny any appropriate insurance reimbursement.

Though BMI is “significantly correlated” with the amount of fat mass in the general populace, it loses predictability when applied to an individual, the group stated.

The AMA is now suggesting that BMI be used in conjunction with other factors like measurements of visceral fat, body adiposity index, body composition, relative fat mass, waist circumference, and genetic or metabolic factors.

“There are numerous concerns with the way BMI has been used to measure body fat and diagnose obesity, yet some physicians find it to be a helpful measure in certain scenarios,” said AMA Immediate Past President Dr. Jack Resneck.

“It is important for physicians to understand the benefits and limitations of using BMI in clinical settings to determine the best care for their patients.”
