Reducing risk of hospitalization in the elderly
Date:7/29/2009

Older adults who have less strength, poor physical function and low muscle density are at higher risk of being hospitalized compared to adults with more strength and better function. That's the finding of a new study in the Journal of the American Geriatric Society.

The study also found that muscle density, a measure of how much fat compared to lean tissue there is in the muscle, is a more accurate gauge of a person's risk of hospitalization than muscle mass or size. The relative risk for hospitizations was 50% higher for those with poor walking or less dense muscle mass

"Our research suggests that we need to re-think the way we define sarcopenia or age-related muscle loss," says Peggy Cawthon, PhD, MPH, a scientist with the California Pacific Medical Center Research Institute and the lead author of the study. "Many definitions of sarcopenia today tend to focus on lean mass or muscle size, our study shows that is looking at the wrong factors. We found that muscle strength or performance were much better ways of measuring function."

The researchers followed 3,011 healthy, non-disabled adults between the ages of 70 and 80, for an average of almost five years. They measured their physical function in a number of ways including walking speed, their ability to stand up from a chair repeatedly, the strength of their grip and their leg strength. By the end of the study more than 55 percent of the participants had experienced one or more hospitalizations. Those most likely to end up in the hospital were the adults who scored lowest on the measures of physical function; this held true after allowing age, medical conditions, lean mass or muscle size. They also found that adults with the least dense thigh muscles, namely those with a higher proportion of fat in their thighs, were also at a higher risk of hospitalization compared to adults with more dense thighs.

"The findings are particularly important because they suggest that
