The body mass index (BMI) may not be the most accurate predictor of death risk.
A new study from the University of Florida found that BMI is usually used to determine whether the weight of the person is in a healthy range For their height – is “deeply wrong” in terms of mortality forecasting.
Instead, one’s level of body fat is “far more accurate,” the study concluded, which was published this week in the Anales of Family Medicine.
BMI is the wrong way to measure obesity, say researchers
In order to measure the body fat of participants, researchers used a method called bioelectric analysis of impedance (BIA), which uses a device for measuring body resistance in small electric current.
During the 15-year-old period, those who had a high body fat is 78% more likely to die of those who had A healthy level of body fatThey found researchers.

They were also more than three times likely to die from heart diseases, the studies noticed.
BMI – calculated by dividing weight by height, square – is described as “entirely unreliable” in the forecasting of the risk of death during the 15-year-old period of any reason.
In the United States, the study included 4,252 people in the United States and pulled data from the National Survey on Health and Nutrition.

BMI should not rely on the “vital sign” of health, according to the senior author Frank Orlando, MD, medical director of UF’s health care in SpringHill.
“I am a family doctor and we are regularly faced with patients who have diabetes, heart disease, obesity and other conditions that are obesity“Orlando said in a statement for studying testing.
Over the 15-year-old period, those who had high bodily fat were more likely to die from those who had healthy levels of body fat, they found researchers. (East)
“One of the routine measures we take with traditional vital signs is BMI. We use BMI to be a problem with their body composition, but it is not so true,” he added that vital signs, “he added.
BMI was an international standard for measuring obesity since the 1980s, according to many sources, although some experts questioned its validity.
“I think the study shows that it’s time to go to an alternative that has now been proven to be far better at work.”
The individual is considered Gojastim if their BMI is 30 years or more, between 25 and 29.9, “Normal” weight in the range of 18.5 to 24.9, or lower weight if less than 18.5.
While BMI is easily calculated, one of the main restrictions is that it cannot distinguish between muscle and oily massResearchers noticed.
“People who are bodybuilders can really elevate the body mass index,” said one doctor. “But they are healthy even with BMI indicating that they are obese.” (East)
“For example, people who bodybuilders can really be the sole of the body mass index,” Orlando said. “But they are healthy even with BMI indicating that they are obese.”
“BMI is just so built in how we think about body fat,” he added the main one. “I think the study shows that it’s time to go to an alternative that has now been proven to be far better at work.”

Other methods, such as DEKA (double-energy X-ray absorptiometry), can be even more accurate than BIA, but are much more expensive, and researchers are not available.
“If you talk to obesity researchers, they will say you have to use Deka Scan Because it’s the most accurate, “Felous said in the commissioning.” And that’s probably true. But it will never be sustainable in a doctor’s office or family practice. “
“It is an easy measuring tool that helps us understand the risk groups in various popuses and demographics, but it does not provide accurate patient patient data,” said the doctor in BMI. (East)
Dr. Stephen Vogel – Family Medicine Doctor with Plushcare, Virtual Health Platform with primary care, therapy and Weight management Options – BMI limitations echoed.
“It was an easy measuring tool that helps us understand risk groups through different populations and demographics, but it does not provide accurate patient patient data,” who was not involved in the study, which was not involved in the study.

“These findings do not challenge the assumptions about BMI – they strengthen the message that new standards, submitted in consistent and low-cost-effective way, provided better NINS for the individual when it comes to their total physical health.”
Potential limitations
“The main forces of this study are a better correlation according to the risk of an individual morbidity and mortality – However, the restrictions in the fact that we do not have enough data to determine the right break for these numbers or to identify the right tools that will be precise and precise by population, “Vogel said.
Researchers also recognized that the thresholds of body fat percentages were still not as standardized as the BMI and the scope of the waist.

Also, the age range of participants in the study is limited by data source.
“Future studies should expand this comparison of BMI body fat in older adults,” researchers wrote.
“These data will drive better discussions in the doctor’s office, as well as public health initiatives with the aim of improving the health of all,” the doctor said. (East)
The study was also limited by focusing only on mortality as an outcome, noted, without taking into account any diseases in development – such as heart failure Or cancer – which could deepen the understanding of body fat as a risk factor.
The goal, according to Vogel, has an economical, consistent method that can be used through a population with reliable accuracy.
“These data will drive better discussions in the doctor’s office, as well as public health initiatives with the aim of improving the health of everyone.”
“The benefits would come in the form of a more detailed list of information that helps givers and patients give informed decisions about patient’s healthWhat is ideal, “Vogel noticed.
“I hope there is enough buzzing around these measures that the steps will continue to take regular use.”

Researchers hope that former standards have been confirmed, a measuring percentage of body fat with a bileographatic impedance analysis could become a standard of care.
They added: “This data will drive better discussions in the doctor’s office as well as Public health initiatives with the aim of improving the health of all. “
