Washington,
Jan 5 (IANS) A higher walking speed could be the key to older adults
surviving for longer, a study suggests. Stephanie Studenski of the
University of Pittsburgh in the US and her colleagues conducted a study
to co-relate gait speed with survival in older adults.
The
study analyzed nine studies between 1986 and 2000 using individual data
from 34,485 community-dwelling adults aged 65 years or above, reports
the Journal of the American Medical Association.
Participants
had an average age of 73.5 years, while 59.6 percent were women and
79.8 percent were white, according to a Pittsburgh statement.
Walking speed was calculated for each participant using distance in meters and time in seconds.
Researchers
said slower walking speed indicated weak organ systems and higher
energy cost of walking, thus indicating poor survival rate.
During
the course of the study, there were 17,528 deaths. The overall
five-year survival rate was 84.8 percent while the 10-year survival rate
was 59.7 percent.
The
researchers found that walking speed was associated with differences in
the probability of survival at all ages in both sexes, but was
especially notable after 75 years of age.
