Obesity may shorten life expectancy up to 8 years

08.12.2014

Canadian researchers put numbers on health risk

‘Tis the season to indulge. However, restraint may be best according to a new study led by investigators at the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University. The researchers examined the relationship between body weight and life expectancy.

Their findings show that overweight and obese individuals have the potential to decrease life expectancy by up to 8 years. The study, published in the current issue of The Lancet Diabetes and Endocrinology, further demonstrates that when one considers that these individuals may also develop diabetes or cardiovascular disease earlier in life, this excess weight can rob them of nearly two decades of healthy life.

“In collaboration with researchers from the University of Calgary and the University of British Columbia our team has developed a computer model to help doctors and their patients better understand how excess body weight contributes to reduced life expectancy and premature development of heart disease and diabetes,” says lead author Dr. Steven Grover, a Clinical Epidemiologist at the RI-MUHC and a Professor of Medicine at McGill University.

Diabetes and cardiovascular disease: the predictors of health

Dr. Grover and his colleagues used data from the National Health and Nutrition Examination Survey (from years 2003 to 2010) to develop a model that estimates the annual risk of diabetes and cardiovascular disease in adults with different body weights. This data from almost 4,000 individuals was also used to analyze the contribution of excess body weight to years of life lost and healthy years of life lost.

Their findings estimated that individuals who were very obese could lose up to 8 years of life, obese individuals could lose up to 6 years, and those who were overweight could lose up to three years. In addition, healthy life-years lost were two to four times higher for overweight and obese individuals compared to those who had a healthy weight, defined as 18.5-25 body mass index (BMI). The age at which the excess weight accumulated was an important factor and the worst outcomes were in those who gained their weight at earlier ages.

“The pattern is clear - the more an individual weighs and the younger their age, the greater the effect on their health,” Dr. Grover adds. “In terms of life-expectancy, we feel being overweight is as bad as cigarette smoking.”

The next steps are to personalize this information in order to make it more relevant and compelling for patients. “What may be interesting for patients are the ’what if?’ questions. What if they lose 10 to 15 pounds? Or, what if they are more active? How will this change the numbers?” says Dr. Grover.

The research team is now conducting a three year study in community pharmacies across the country to see if engaging patients with this information and then offering them a web-based e-health program will help them adopt healthier lifestyles, including healthier diets and regular physical activity.

“These clinically meaningful models are useful for patients, and their healthcare professionals, to better appreciate the issues and the benefits of a healthier lifestyle, which we know is difficult for many of us to adopt and maintain, Dr. Grover adds.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
