No walk in the park: Factors that predict walking difficulty in elderly

17.01.2012
Yale School of Medicine researchers have found that the likelihood of becoming disabled with age increases with the following factors: having a chronic condition or cognitive impairment; low physical activity; slower gross motor coordination; having poor lower-extremity function; and being hospitalized. Women are also more likely than men to become disabled in their later years.

Based on 12 years of data, the findings are published in the Jan.17 issue of Annals of Internal Medicine by a research team led by Thomas Gill, M.D., the Humana Foundation Professor of Geriatric Medicine and professor of medicine, epidemiology, and public health at Yale School of Medicine.

With age, many people can no longer walk short distances or drive a car, and those with long-term loss of mobility have difficulty regaining independence.

"Losing the ability to walk independently not only leads to a poorer overall quality of life, but prolonged disability leads to higher rates of illness, death, depression and social isolation," said Gill, who followed a group of 641 people aged 70 or older who could walk a quarter mile unassisted or who were active drivers at the start of the study. All participants could perform essential activities of daily living, such as bathing and dressing.

Gill and his team assessed the participants for changes in potential disability risk factors every 18 months between 1998 and 2008. They also assessed the participants' mobility each month. Those who said they needed help from another person to walk a quarter mile were considered to be walking disabled. Those who said that they had not driven a car during the past month were considered driving disabled.

On a monthly basis, the research team also assessed the participants' exposure to potential causes of disability, including illnesses or injuries leading to hospitalization and restricted activity, which increased the likelihood of long-term disability by 6-fold.

The team found that multiple risk factors, together with subsequent illness and injury leading to hospitalization and restricted activity, are associated with an increased likelihood of developing long-term walking and driving disability. The team considered a disability to be long term if it persisted for at least six months.

"We've learned that targeted strategies are needed to prevent disability among older people living independently in the community," said Gill.

Other authors on the study include Eveleyne A. Gahbauer, M.D.; Terrence E. Murphy; Ling Han, M.D.; and Heather G. Allore.

The National Institute on Aging funded the study, which was conducted at the Yale Pepper Center/Program on Aging.

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...

Im Focus: Modelling leads to the optimum size for platinum fuel cell catalysts: Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.

Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
