TUESDAY, July 5 (HealthDay News) -- Healthy living significantly
reduces a woman's risk of sudden cardiac death, a new study
Researchers analyzed data from about 82,000 women who
participated in the Nurses' Health Study from 1984 to 2010. During
those 26 years, there were 321 cases of sudden cardiac death among
the women. The average age of women who died was 72.
Four low-risk lifestyle factors were significantly and
independently associated with a lower risk of sudden cardiac death:
not smoking; having a body mass index lower than 25; exercising at
least 30 minutes per day; and consuming a Mediterranean-style diet
that included plenty of vegetables, fruits, nuts, legumes, whole
grains and fish, with moderate alcohol intake.
Women who adhered to all four low-risk lifestyle factors had a
92 percent lower risk of SCD than those who didn't have any of the
low-risk factors, said Stephanie Chiuve, of Brigham and Women's
Hospital and Harvard Medical School in Boston, and colleagues.
Their study appears in the July 6 issue of the
Journal of the American Medical Association.
Each year in the United States, there are 250,000 to 310,000
cases of sudden cardiac death, which accounts for more than half of
all cardiac deaths, according to the researchers.
The U.S. National Heart, Lung, and Blood Institute has more
sudden cardiac arrest/death.
