The study leads to the fact that the body mass index is actually accurate in measuring American obesity

The body mass index may be more accurate than it was usually believed. New research shows that the vast majority of people with a body mass index indicate obesity have excess body fat.

Scientists at Johns Hopkins University conducted the study, Published This month in Gamma. In a representative sample at the national level of Americans, they found that adults with a body mass index suffer from obesity always meet obesity criteria in terms of waist envelope or body fat as well. The results indicate that the BMI is still an important tool at the population level to assess obesity, as researchers say, even as many people try to get out of it.

The researchers analyzed the data from the National Health and Nutrition Examination (NHANES), a survey of the diet and lifestyle of the Americans managed by the centers of control and prevention of diseases regularly. As part of NHANES, some people are given more comprehensive checks, which include tests that measure body fat or waist circumstance.

The researchers looked at the latest NHANES data (2017-2018) that included people who received these other tests in addition to examining the BMI. Obesity is usually defined as the presence of a 30 or more body mass index (27 for people of Asian origin). But it can also be defined by obtaining a 25 % percentage of body fat for men, 35 % for women, or 40 -inch waist envelope for men and 35 inches for women.

The researchers found that more than 98 % of people who are considered obese using the body mass index alone are proportional to the bill when either waist or body fat conditions were taken into account.

The researchers wrote: “Although some patients (for example, athletes) may guarantee more evaluation, our results indicate that these individuals are a very small part of the population,” the researchers wrote.

Results are particularly relevant given the recent developments in the field of obesity medicine. Earlier in January, a large group of experts invited Drama In how to diagnose obesity.

They have paid doctors to stop using a body mass index as only standards to measure obesity. Instead, they say that doctors should either use two body size (one of which includes a body mass index) or a direct measurement of fat in the body to diagnose obesity. They also called for the assembly of obesity in two wide categories, depending on whether a person’s obesity actively caused health problems: obesity before clinical and clinical.

The researchers and other preachers in the positive body and the movement of fat acceptance have long demanded the gradual disposal of the BMI, and the group’s conclusions were strongly supported by many public health groups, including the American Heart Association and the World Obesity Union.

However, the study researchers note that direct fat tests in the body require specialized equipment and may be more expensive for patients in terms of costs outside the pocket, and given the results they reached, many people may not benefit from undergoing these other tests. Either way, it seems likely that the scientific debate about the benefit of the body mass index has not yet been settled.

The authors wrote: “For almost all adults with high body mass index, there may be a limited benefit to confirm excess fat.” Currently, according to the current BMI criteria, around it 40 % of adults in the United States Bena is considered, although the rate may start Finally retreatedPartially due to the arrival of the latest and most effective medications in weight loss like Wegovy.
