NIH-commissioned report highlights disability among older population

Almost 16 million Americans aged 65 and older report having at least one disability, according to a new report by the U.S. Census Bureau (PDF, 1.5M), commissioned and funded by the NIA. This is the first Census report on disabilities among older people and looks at disability status by age, sex, marital status, education, and poverty status.

Structured physical activity program can help maintain mobility in vulnerable older people

A carefully structured, moderate physical activity program can reduce risk of losing the ability to walk without assistance, perhaps the single most important factor in whether vulnerable older people can maintain their independence, a study has found.

Older people who lose their mobility have higher rates of disease, disability, and death. A substantial body of research has shown the benefits of regular physical activity for a variety of populations and health conditions. But none has identified a specific intervention to prevent mobility disability.

Research consortium including NIH proposes diagnostic criteria for sarcopenia

Sarcopenia, a loss of muscle mass often associated with weakness, is a commonly recognized cause of disability in older people. However, without consensus on ways to specifically measure this condition, the development of interventions for sarcopenia has been challenging. Now, a team of researchers proposes a comprehensive set of diagnostic criteria, presented April 15, 2014, in six special articles in the Journals of Gerontology: Medical Sciences.
