Study: More exercise, less sitting reduces heart failure risk for men – Westhill Consulting Insurance
By
DALLAS — sitting for long period’s increases heart failure risk in men, even for
those who exercise regularly, according to new research published in the
American Heart Association journal Circulation: Heart Failure.
Preventing heart
failure, researchers found, requires a two-part behavioral approach: high
levels of physical activity plus low levels of
sedentary time. The study is the first to examine the link between heart
failure risk and sedentary time, said Deborah Rohm Young, Ph.D., lead
researcher and a senior scientist at Kaiser Permanente in Pasadena, Calif.
"Be more active and sit less. That's the message
here," Young said.
Researchers followed a
racially diverse group of 84,170 men ages 45 to 69 without heart failure.
Exercise levels were calculated in METs, or metabolic equivalent of task, a
measure of the body's energy use. Sedentary levels were measured in
hours. After an average of nearly eight years of follow-up, researchers
found:
Men with low levels of
physical activity were 52 percent more likely to develop heart failure than men
with high physical activity levels, even after adjusting for differences in
sedentary time.
Outside of work, men
who spent five or more hours a day sitting were 34 percent more likely to
develop heart failure than men who spent no more than two hours a day sitting,
regardless of how much they exercised.
Heart failure risk
more than doubled in men who sat for at least five hours a day and got little
exercise compared to men who were very physically active and sat for two hours
or less a day.
Study limitations
included: Since no women were studied the results may not apply to them;
results were self-reported, which could mean physical activity was over
reported; results were based only on time outside of work and can't be applied
to overall sedentary activity; and participants were members of comprehensive
health plans, so results may not apply to men lacking health insurance.
The study supports the
American Heart Association recommendation that people get at least 150 minutes
a week of moderate-intensity aerobic activity to reduce their risk for heart
failure and other cardiovascular diseases, Young said.
