NEW YORK (Reuters Life!) - Slow walking may not only mean getting to your destination later but it could also be taking its toll on your health, according to a French study.

Researchers from the Paris-based medical research institute Inserm found that older people who walk slowly are almost three times more likely to die of heart disease and related causes than older people who walk faster.

"The main message for the general population is that maintaining fitness at older age may have important consequences and help preserve life and (muscle) function," researcher Alexis Elbaz, director of research at Inserm, told Reuters Health.

He said the study, which appeared in the journal BMJ, also suggests that a test of walking speed might be used to test the health of elderly patients.

Previous studies had linked slow walking speed with increased risk of death over a given period, as well as with falls and other bad health outcomes, but hadn't shown whether it was heart disease or another cause that accounted for that higher risk.

The five-year study, part of Inserm's ongoing Three City Study, involved more than 3,200 relatively fit men and women, aged 65 to 85, living in three French cities.

At the start of the study in 1999, the scientists assessed the health of each participant and clocked the participants' speeds as they walked down a corridor as fast as possible.

Over the next five years, 209 of the participants died -- 99 from cancer, 59 from heart disease, and 53 from infectious diseases and other causes - for an overall death rate of almost 7 percent.

The death rate among the slowest-walking one-third of participants - those men who walked at the equivalent of about 3.4 miles per hour or slower and women who walked at about 3 miles per hour or slower -- was 44 percent higher than that among the two-thirds of participants who had walked faster.   Continued...
