According to research conducted at Rush University Medical Center, higher levels of social activity are associated with a decreased risk of becoming disabled. The study has just been posted online and will be published in the April issue of the Journal of Gerontology: Medical Sciences.
"Social activity has long been recognized as an essential component of healthy aging, but now we have strong evidence that it is also related to better everyday functioning and less disability in old age," said lead researcher Bryan James, PhD, postdoctoral fellow in the epidemiology of aging and dementia in the Rush Alzheimer's Disease Center. "The findings are exciting because social activity is potentially a risk factor that can be modified to help older adults avoid the burdens of disability."
The study included 954 older adults with a mean age of 82 who are participating in the Rush Memory and Aging Project, an ongoing longitudinal study of common chronic conditions of aging. At the start of the investigation, none of the participants had any form of disability. They each underwent yearly evaluations that included a medical history and neurological and neuropsychological tests.
Social activity was measured based on a questionnaire that assessed whether, and how often, participants went to restaurants, sporting events or the teletract (off-track betting) or played bingo; went on day trips or overnight trips; did volunteer work; visited relatives or friends; participated in groups such as the Knights of Columbus; or attended religious services.
To assess disability, participants were asked whether they could perform six activities of daily living without help: feeding, bathing, dressing, toileting, transferring and walking across a small room. They were also asked whether they could perform three tasks that require mobility and strength: walking up and down a flight of stairs, walking a half mile and doing heavy housework. Finally, they were asked about their ability to perform what are referred to as "instrumental" activities of daily living, such as using the telephone, preparing meals and managing medications. Difficulties with household management and mobility are more common and represent less severe disability than difficulty with self-care tasks, so the measures represented a range of disability.
Results showed that a person who reported a high level of social activity was about twice as likely to remain free of a disability involving activities of daily living than a person with a low level of social activity, and about 1.5 times as likely to remain free of disability involving instrumental activities of daily living or mobility.
Why social activity plays a role in the development of disability is not clear, James said. Possibly, social activity may reinforce the neural networks and musculoskeletal function required to maintain functional independence.
Future research is needed to determine whether interventions aimed at increasing late-life social activity can play a part in delaying or preventing disability, James said.
Other researchers at Rush involved in the study were Patricia Boyle, PhD, Dr. Aron Buchman and Dr. David Bennett.
Rush is a not-for-profit academic medical center comprising Rush University Medical Center, Rush University, Rush Oak Park Hospital and Rush Health.
Rush is currently constructing a 14-floor, 806,000-square-foot hospital building near the corner of Ashland Avenue and the Eisenhower Expressway. The new hospital, scheduled to open in 2012, is the centerpiece of a $1 billion, ten-year campus redevelopment plan called the Rush Transformation, which also includes completion of a new orthopedics building, a new parking garage and central power plant, renovations of selected existing buildings and demolition of obsolete buildings. In January, Rush opened the new Rush University Cancer Center in completely renovated facilities in its Professional Buildings. The new hospital is designed and built to conserve energy and water, reduce waste and use sustainable building materials. Rush is seeking Leadership in Energy and Environmental Design (LEED) gold certification from the U.S. Green Building Council. It will be the first full-service, "green" hospital in Chicago.
Rush's mission is to provide the best possible care for its patients. Educating tomorrow's health care professional, researching new and more advanced treatment options, transforming its facilities and investing in new technologies—all are undertaken with the drive to improve patient care now, and for the future.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
