Get
moving for a longer life free of diabetes
NEW
YORK (Reuters Health Mon Jan 2, 2006 8:48 PM GMT)-The results of a new study may motivate couch potatoes to get moving
in the New Year. According to the study, people who are physically active live
longer and spend more years free of diabetes than people who are inactive.
Using data from the Framingham Heart Study, which has followed some
5,200 residents of Framingham,
Massachusetts, over the past 46
years, researchers calculated the differences in life expectancy in subjects
with and in those without diabetes associated with different levels of physical
activity.
They found that at age 50 life expectancy free of diabetes is 2.3
years longer for moderately active individuals and at least 4 years longer for
highly active individuals.
“The effect of physical activity on life expectancy without diabetes
reflects both the lower incidence of diabetes and the lower mortality of
nondiabetic individuals associated with increasing physical activity,” Dr.
Wilma J. Nusselder from Erasmus Medical Center
in Rotterdam, the Netherlands and colleagues report
in Diabetes Care.
The study also shows that life expectancy with diabetes is roughly
0.5 years less for moderately active people and 0.1 years less for highly
active people compared with their sedentary counterparts.
This reflects two opposing effects-lower
incidence of diabetes in people who are active, reducing the time spent with
diabetes-and lower mortality in those with diabetes,
increasing the time spent with diabetes.
“Our study suggests that if sedentary people could be stimulated to
be at least moderately active, they could extend their lives and increase their
life-time spent without diabetes,” the team concludes.
