Study: Being overweight is not necessarily associated with premature death



Study: Being overweight is not necessarily associated with premature death

DUBAI, United Arab Emirates, (CNN) — A new study has found that obesity, as measured by BMI, is not associated with obesity when viewed separately from other health problems.

BMI for adults is calculated by dividing weight by the square root of a person’s height, and people have different amounts of body fat.

According to the US Centers for Disease Control and Control (CDC), an adult is considered overweight if his BMI is between 25 and 29.9, and if the index is between 18.5 and 24.9, his weight is considered normal or healthy, and if it exceeds 30. , he is considered overweight. He suffers from obesity.

Dr. Ayush Visaria, MD, a resident physician specializing in internal medicine at Rutgers Robert Wood Johnson Medical College in New Brunswick, New Jersey, said the real news from this study is that weight gain is defined by BMI. is a poor predictor of mortality risk, and weight gain is a predictor of mortality risk. Body mass index is generally a poor predictor of health risks and should be supplemented with information provided by waist circumference, other measures of fatness, and other measurements. weight path.

According to experts not involved in the study, research limitations make it difficult to determine whether the results are due to BMI or other factors.

Dr. is a lecturer in clinical statistics at University College London. Baptiste Laurent explained, “The use of the term ‘overweight’ is misleading here because it excludes anyone with a BMI over 30. He said in a statement that the term ‘overweight’ includes anyone who weighs more than the “normal” index, including those who are obese. Generally explained.

“This paper finds a clear association between BMI and mortality before and after adjusting for risk factors,” added Laurent, who was not involved in the study.

Dr. Robert H., senior faculty editor at Harvard Health Publishing, affiliated with Harvard Medical School in Boston. Schmerling said observational studies only show correlation, not causation.

“They looked at mortality rates, but they didn’t look at other important outcomes, such as quality of life or the development of new comorbidities like new diabetes or heart disease,” Schmerling, who was not involved, said. study, said.

Death vs. Disease

In a new study published Wednesday in the journal PLOS ONE, researchers analyzed data on more than 554,000 non-pregnant Americans over the age of 20 collected from the 1999-2018 National Health Interview Survey and the 2019 US National Death Index.

Visaria, professor of medicine and epidemiology at Rutgers Robert Wood Johnson School of Medicine and Rutgers School of Public Health, and co-author Dr. Soko Setoguchi compared BMI levels with recorded deaths over the next 20 years.

Visaria noted that mortality risk increased from 18 to 108% for those with a BMI greater than 27.5, and that risk increased with overweight following a U-shaped curve.

There was one exception: adults over 65. There was no significant increase in mortality among older adults with a BMI between 22.5 and 34.9, a range that includes normal weight, overweight, and obese people.

“This paper adds nothing new,” says Naveed Sattar, a professor of cardiovascular health and metabolism at the University of Glasgow in Scotland, who was not involved in the study.

“We know that BMI often yields a U-shaped curve with mortality, but many people at the lower end of the BMI range (especially older people) experience unintentional weight loss,” Starr said in a statement. due to illness”.

Weight loss is often associated with the development of dementia and cancer, and loss of appetite in elderly patients. Previous research has found that losing at least 5% of body mass increases the risk of premature death among people 65 and older, especially men.

The study’s most important finding was that adults aged 20 to 65 with a body mass index of 24.5 to 27.5, the lowest end of the overweight scale, had no significant increase in mortality risk.

However, Tom Saunders, emeritus professor of nutrition and dietetics at King’s College London, who was not involved in the study, said future risk of disease is “the most important measure of health for all causes”.

“The main risk of being overweight (BMI 25-29.9) and moderately obese (BMI 30-35) is a threefold higher risk of developing diabetes, which contributes to cardiovascular disease, kidney failure and blindness,” he said in a statement. .

Visaria told CNN that while the study controlled for various diseases linked to smoking and premature death, the information was collected only once for each person who participated in the survey. Therefore, the study was unable to follow him later to see if he developed conditions that may have contributed to death, such as high blood pressure or diabetes, which is one of the study’s limitations.

“They don’t look at the cause of death, maybe it was a car accident or something unhealthy,” says Schmerling, former medical chief of rheumatology at Beth Israel Deaconess Medical Center in Boston.

“Besides, if you look at the big picture results, they found an increase in mortality due to obesity, so it’s not like they’re proving the usefulness of BMI for all purposes.”

Schmerling said people in the overweight category can make lifestyle changes, such as exercising, eating a healthy diet and seeking medical help, to avoid developing diabetes, heart disease or other comorbidities.

Waist circumference is an important measurement

Visaria noted that for BMI, they also examined data measuring waist circumference or abdominal thickness. The results showed that using waist circumference “significantly modifies the association between BMI and all-cause mortality.”

“People with a larger waist circumference were at higher risk of death than those with a normal waist circumference in the same BMI groups,” he added. “In the overweight BMI range (25-29.9), the risk of death was 17 to 27% higher among those with a high waist circumference compared to those with a low waist circumference,” he added.

This type of deep fat around body parts, known as abdominal or visceral fat, has been linked to a 39% higher risk of dementia in older women, and heart disease, frailty and early death in both sexes.

According to guidelines published by the American Heart Association in April 2021, waist circumference should be measured as part of any health evaluation.

And the American Medical Association recently adopted new guidelines calling on doctors to use more than BMI when assessing an individual’s health.

Can earthquakes be predicted using artificial intelligence models?



Can earthquakes be predicted using artificial intelligence models?

The painful earthquakes in Turkey, Morocco and Afghanistan in 2023, which caused severe losses beyond thousands of deaths and injuries and severe damage to infrastructure, confirm the importance of constructing earthquake-resistant buildings. Many technological solutions are now available to increase the resistance of buildings to earthquakes, which may protect lives or mitigate their psychological and economic effects and consequences. Many international universities are also racing to develop technologies that can help predict earthquakes using artificial intelligence.

Earthquake resistant designs

Earthquake-resistant design includes a range of technologies and methods to improve a building’s ability to withstand seismic forces. In an exclusive interview with Asharq Al-Awsat, architect Muhammad Obaid, founder and CEO of Emcon Architecture and Engineering Consultancy, explains the basic techniques and methods currently used in earthquake-resistant design. “Basic isolation systems range from shear walls, moment-resisting frames, anchorage systems, tuned mass dampers, viscous dampers, reinforced concrete, steel framing, flexible materials, energy dissipation devices, seismic retrofitting, design of non-structural components,” Obaid said. says. , and soil optimization, seismic hazard assessment, computer modeling and simulation, and building codes and standards.” He adds, “Engineers and architects combine these techniques and methods to create detailed earthquake-resistant designs designed to meet the specific needs and conditions of the building and its location, and the choice of techniques depends on factors such as the type of building, location, budget, and level of seismic risk.” “

Architect Mohammad Obaid is the Founder and CEO of “EMKON” Architectural and Engineering Consulting Firm (EMKON).

Restoration of old buildings

Retrofitting existing buildings with sustainable, earthquake-resistant technologies is certainly possible, but it requires careful planning, engineering expertise and compliance with local regulations. Architect Muhammad Obaid, speaking to Asharq Al-Awsat, believes that “existing buildings can be modernized with sustainable and earthquake-resistant technologies, although the process varies in complexity depending on the specific technologies and the structural and architectural characteristics of the building.” Some of the considerations for retrofitting existing buildings with these techniques include “structural retrofitting, material improvements, architectural considerations, engineering expertise, building codes and permits, cost considerations, phased approach, seismic evaluation and integration of sustainable technologies,” he explains. “Operational challenges and issues vary from one building to another, and a customized approach is often necessary to achieve desired seismic and sustainability goals while minimizing disruption to building occupants,” he notes.

Anticipating aftershocks

Stanford University researchers have developed an artificial intelligence model that can predict aftershocks after an earthquake with more than 80 percent accuracy.

The model was trained on a dataset of more than 700,000 earthquakes from around the world, and it was able to identify patterns in more complex data that traditional methods could not detect, the researchers report.

The model works by analyzing seismic activity data sources, geological data and machine learning algorithms to identify patterns and trends associated with the occurrence of earthquakes. It can predict the size and timing of a setback. The model is still under development, but it can be a valuable predictive tool that can improve the accuracy and timeliness of aftershock warnings and help save lives and property.

High precision Japanese model

Scientists at the University of Tokyo have succeeded in developing a model called Deep Learning Earthquake Prediction Model (DLEPM) that can predict with high accuracy by analyzing seismic activity patterns. The model was trained on a dataset of over 10 million seismic events from around the world. DLEPM analyzes a variety of data sources, including geographic data and machine learning algorithms. Japanese university researchers say it has proven to be very accurate in predicting. It is 80 percent successful in predicting magnitude 6 or greater earthquakes within a week of their occurrence.

“DLEPM” is still under development, but its potential is not limited to saving lives and property, but improving researchers’ understanding of earthquake processes and how and why they occur to develop new strategies to prevent them and mitigate their effects.

Prediction of crack friction

Another AI model that can predict future fault friction is called the Deep Learning Fault Friction Model (DLFFM), developed by scientists at Los Alamos National Laboratory in the US.

Trained on a dataset of more than one million laboratory earthquakes, the model analyzes various data sources to identify patterns and trends associated with fault friction. They can be used to predict future friction at a given location, and how friction will change over time. DLFFM is still under development, but could be a valuable tool for improving the accuracy and timeliness of earthquake warnings.

The innovative Japanese method

Japan is located on the Pacific “Ring of Fire” and is known for frequent seismic activity, prompting the design and construction of earthquake-resistant buildings.

An architectural firm affiliated with Kengo Kuma used carbon fiber to stabilize buildings and protect them from earthquakes. These materials are made from thermoplastic carbon fiber, a material with amazing tensile strength that rivals traditional building materials like steel. The innovation provides additional reinforcement to the building structure as carbon fiber ropes extend through a metal frame above the eco-friendly roof and then drop down the sides to reach the ground. Carbon fibres, separated in curtain-like fashion, form doors that lead to interior spaces draped over time and covered in white fabric.

Cost of earthquake resistant buildings

Earthquake-resistant technologies can have a significant impact on the overall cost of a construction project. While these technologies are essential to ensure a building’s safety and resilience during seismic events, they can also add cost to a project. Architect Muhammad Obaid, founder and CEO of Imcon Architecture and Engineering Consulting, explains in an exclusive interview with Asharq Al-Awsad, “The degree of this influence depends on various factors, including specific technologies, the location of the project, the type of building and the level of seismic hazards. “Earthquake He believes that resisting technologies, materials and components, complexity of structural design, special systems, foundation systems, quality control and inspection, architectural modifications, seismic retrofits, local building codes, and degree of seismic risk affect construction costs. Project size and complexity and maintenance and life cycle costs.

While earthquake-resistant technologies add upfront construction costs, they also lead to long-term benefits. Architect Muhammad Obaid says, “These benefits include increased safety, lower repair and reconstruction costs after an earthquake, and a possible reduction in insurance premiums. Some regions offer incentives or subsidies to cover the initial costs of incorporating earthquake-resistant technologies.” Generally, building an earthquake-resistant building costs more than a conventional building. According to architect Muhammad Obaid, this cost is “10 percent to 30 percent more than the cost of building a conventional building.”

The most dangerous of them is the “breath of the dead” … Bad breath is a symptom of these serious diseases



The most dangerous of them is the “breath of the dead” … Bad breath is a symptom of these serious diseases

Some metabolic disorders can cause bad breath due to various problems in the intestines, blood or liver.

The following are the most important medical conditions that can cause complications:


  • A common condition that causes bad breath in the mouth and throat is diabetes because high glucose levels can cause the growth of harmful bacteria.
  • Because people with diabetes have insulin problems, cells may not get the glucose they need for energy, and instead the body starts burning fat-forming compounds called ketones.
  • Ketones accumulate in the blood and urine and cause bad breath.
  • One of these ketones is acetone, and it can cause breath to smell like nail polish.
  • If someone with diabetes notices the smell, they should seek medical advice as it could be due to diabetic ketoacidosis, a life-threatening condition.

Liver disease

  • If a person’s breath has a strong, foul smell, this is a sign that the liver is not filtering out toxins.
  • Doctors call this distinctive smell “the breath of the dead” because of its association with severe and fatal liver disease.

Kidney disease

  • Chronic kidney disease is a condition in which the kidneys are damaged and cannot filter the blood properly, which is why excess fluids and waste from the blood can build up in the body and cause other health problems such as heart disease and stroke.
  • People with kidney failure may develop bad breath.
  • As the kidneys begin to fail, the metabolic urea cannot be excreted effectively in the urine, and it accumulates in the blood and saliva.
  • The body converts urea into ammonia, which causes bitterness in the mouth and bad breath.
  • One in three people on dialysis say their breath smells like urine.

Too much methionine in the blood

  • It is an increase in a specific protein building block (amino acid) called methionine in the blood.
  • People with this condition often have no symptoms, but if their breath, sweat, or urine smells like boiled cabbage, they should see a doctor.
