Obesity and Knee Osteoarthritis Shorten Healthy Years of Life

16.02.2011
An estimated 10 million Americans suffer from knee osteoarthritis (OA), making it one of the most common causes of disability in the US.

Due to obesity and symptomatic knee OA, Americans over the age of 50 will together lose the equivalent of 86 million healthy years of life, concluded researchers at Brigham and Women’s Hospital (BWH), who investigated the potential gains in quality and quantity of life that could be achieved averting losses due to obesity and knee OA. These findings are published in the February 15 issue of Annals of Internal Medicine.

“Reducing obesity to levels observed in 2000 would prevent 172,792 cases of coronary heart disease, 710,942 cases of diabetes, and 269,934 total knee replacements,” said Elena Losina, PhD lead author of the study and co-director of Orthopedics and Arthritis Center for Outcomes Research in the Dept of Orthopedic Surgery at BWH. “All told, it would save roughly 19.5 million years of life among US adults aged 50-84.”

Experts have long known that knee osteoarthritis is on the rise among Americans, due in part to the growing obesity epidemic and longer life expectancy. Obesity and knee OA are among the most frequent chronic conditions in older Americans. However, how that translates into years of healthy life lost has not been accurately estimated. Dr. Losina and colleagues used a mathematical simulation model to assemble national data on the occurrence of knee OA, obesity and other important conditions such as coronary heart disease, diabetes, cancer and chronic lung disease. Their analysis examines the contribution of both obesity and knee OA to losses in quantity and quality of life. It also evaluates how those losses are distributed among racial and ethnic subpopulations in the United States.

“There are 86 million healthy years of life at stake, a disproportionate number of them being lost by Black and Hispanic women,” said Jeffrey N. Katz, MD, Director of the Orthopedics and Arthritis Center for Outcomes Research at the BWH and a senior author of the study. “These staggering numbers may help patients and physicians to better grasp the scale of the problem and the potential benefits of behavior change.”

This study was funded by grants from National Institute of Arthritis, Musculoskeletal and Skin Disease and the Arthritis Foundation. Contributing authors include Rochelle P. Walensky, MD, MPH, Massachusetts General Hospital, William M. Reichmann, MA, Holly L. Holt, Hanna Gerlovin, Daniel H. Solomon, MD, MPH and Jeffrey N. Katz, from Brigham and Women’s Hospital, David Hunter MD from University of Sydney, Australia, Joanne M. Jordan, MD from University of North Carolina, Chapel Hill, Drs. Lisa Suter and A. David Paltiel, from Yale University School of Medicine.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
