The body mass index (BMI) may not be the most accurate predictor of the risk of death.
A new study from the University of Florida has shown that BMI is the measurement that is commonly used to determine whether the person’s weight is in A healthy range For their growth – “deep” in terms of forecasting.
Instead, the fat level in the body is “much more accurate”, concluded a study that was published this week in “Family Medicine Annals”.
BMI – This is the wrong way to measure obesity, the researchers say
To measure fat in the body, the researchers used a method called bioelectric analysis of impedance (BIA), which uses a device to measure body tissue resistance to a small electric current.
During the 15-year-old period those who had high fat are 78% more likely to die than those who had A healthy level of fat in the bodyThe researchers found.

The study also noted more than three times, most likely to die from heart disease.
The BMI is calculated by the division of mass to height, in the square-was described as “completely unreliable” when predicted the risk of death during the 15-year period from any cause.
The study included 4252 people in the US and pulled data from a national health and nutrition survey.
Men face a higher risk of cancer at this particular fat measurement in the body
According to the senior author Frank Orlando, the medical director of family medicine UF Health Family Medicine in Springhile, BMI cannot be relied on as a “vital sign” of health.
“I am a family doctor, and regularly we face patients who have diabetes, heart disease, obesity and other conditions that have associated with obesity“,” Orlando said in a press release for research.

“One of the usual measures we take along with traditional life signs is BMI. We use BMI to check for a person who has problems with his body composition, but it’s not as true for everyone as vital signs,” he added.
According to many sources, BMI has been an international standard of measuring obesity since the 1980s, although some experts have questioned its authenticity.
“I think the study shows that it’s time to go to the alternative that is now proven much better at work.”
An individual is considered obesity, if BMI is 30 and above, overweight, if it is from 25 to 29.9, “ordinary” weight in the range of 18.5 to 24.9, or with insufficient weight if below 18.5.
While BMI is easy to calculate, one of its basic restrictions is that it cannot distinguish between muscle and fat massThe researchers noted.
“People who are bodybuilders can really raise the body mass index,” one doctor said. “But they are healthy even with the BMI, which indicates that they are obese.” (Istock)
“For example, people who are bodybuilders can really raise the body mass index,” Orlando said. “But they are healthy even with the BMI, which indicates that they are obese.”
“BMI is just so rooted in how we think about fat in the body,” the main thing added. “I think the study shows that it’s time to go to the alternative that is now proven much better at work.”
Experimental drug helps patients lose almost a quarter body weight in early trials
Other methods such as Dexa (X -ray absorbing net) may be even more accurate than Bia, but much more expensive and not available, the researchers note.
‘When you talk to obesity researchers, they are going to say you should use Scan Dexa Because this is the most accurate, ”said the main release. – And this is probably true. But it will never be viable in a doctor’s office or family practice. “
“It was a simple measurement tool that helps us understand the risk groups in different populations and demographics, but it does not provide accurate data from the patient,” the doctor said. (Istock)
Dr. Stephen Vogel – Family Medicine doctor with Plushcare, virtual health care platform, therapy and therapy Managing weighing Options – repeated BMI restrictions.
“It was a simple measurement tool that helps us understand the risk groups in different populations and demographics, but it does not provide accurate data from the patient,” said Fox News Digital, who did not participate in the study.

“These conclusions do not dispute the assumptions about the BMIs strengthen the message that the new standards provided by a consistent and inexpensive way provide a better nuance for a person when it comes to their overall physical health.”
Potential restrictions
“The main strong parties of this study are the best correlation with a person’s risk Disease and mortality “However, the restrictions are that we lack the data to determine the correct cut for these figures, or determine the correct tools that will be accurate and accurate for the population,” Vogel said.
Researchers also acknowledged that the thresholds of interest in the body have not yet been standardized as BMI and the waist circumference.

In addition, the age range of the study participants was limited by the data source.
“Future studies should expand this fat comparison at the elderly,” the researchers write.
“This data will lead to better discussions in the doctor’s office, as well as public health initiatives to improve everyone’s health,” the doctor said. (Istock)
The study was also limited to focus only on mortality as a result, they noted, not considering any developing diseases – for example, heart failure Either cancer – it can deepen the body’s fat understanding as a risk factor.
According to Fohel, the goal is to have a cost -effective, consistent method that can be used for the population with reliable accuracy.
“This data will lead to better discussions in the doctor’s office, as well as public health initiatives to improve everyone.”
‘Benefits will come as a more detailed list of information that helps providers and patients make justified decisions patient’s healthWhat is ideal, – said Vogel.
“I hope that there are enough noise around these measures that will continue until regularly.”

Researchers hope that after checking the standards measurement of fat percentage through bioelectric analysis of impedance may become a health care standard.
They added: “This data will provide the best discussions in the doctor’s office as well Public Health Initiatives to improve health of everyone. “
