Too Much Sitting Linked To Women's Cancer Risk by Tomrock007(m): 7:49am On Jul 20, 2015 |
Sitting for a long time is linked with a variety of
diseases, including an increased risk of Type 2
diabetes and cardiovascular disease. Now, a
new study finds that sitting may be particularly
harmful for women by raising their risk of
developing several cancers.
Women in the study who sat more than 6 hours
a day were at a higher risk of developing breast
cancer, ovarian cancer and the blood cancer
multiple myeloma compared with women who
sat less than 3 hours a day.
In addition to raising women's risk of these
specific cancers, the study also showed that
"Longer leisure time spent sitting was
associated with a higher risk of total cancer risk
in women," the researchers wrote in their study.
Women who sat for more than 6 hours a day
had a 10 percent increase in their risk of
developing any cancer, according to the findings
published June 30 in the journal Cancer
Epidemiology, Biomarkers & Prevention.
The researchers looked at about 70,000 men
and 77,000 women who participated in a long-
running study called the American Cancer
Society Cancer Prevention Study II Nutrition
Survey cohort. Over 17 years, from 1992 to
2009, more than 12,000 women and 18,000
men in the study were diagnosed with cancer.
The researchers controlled for multiple factors
including BMI and physical activity levels. [ Don't

Most men did not appear to be at an increased
risk for cancer from too much sitting. Among
men who were obese, however, sitting for long
periods of time was associated with an 11
percent increased risk of developing cancer,
according to the study, which was led byAlpa
Patel, an epidemiologist at the American
Cancer Society.
The researchers said additional study was
needed to confirm the findings, but the study
was just the latest in a large group of findings
that have highlighted how too much sitting may
have long-lasting health consequences.
In a 2010 study that Patel also led, researchers
found that sitting for long periods was
associated with a host of health conditions
including cardiovascular disease and Type 2
diabetes. Those findings suggested that sitting
and being less active might affect how
metabolic chemicals in the body regulate
numerous systems in the body, according to the
researchers.
That study also found that women who sat for 6
or more hours daily were 37 percent more
likely to die over a 13-year period compared
with those who sat for 3 hours or less daily. For
men, the risk of dying increased 17 percent
over the same period for those who sat at least
6 hours a day.
"Several factors could explain the positive
association between time spent sitting and
higher all-cause death rates," Patel said in a
statement. "Prolonged time spent sitting,
independent of physical activity, has been
shown to have important metabolic
consequences, and may influence things like
triglycerides, high-density lipoprotein,
cholesterol, fasting plasma glucose, resting
blood pressure and leptin, which are
biomarkers of obesity and cardiovascular and
other chronic diseases."
Earlier this year, a study published in the
journal Annals of Internal Medicine found that
people who sit for long periods were 24 percent
more likely to die during the course of the
study, including those who were more active
after long periods of sitting.
"More than one-half of an average person's day
is spent being sedentary — sitting, watching
television or working at a computer," Dr. David
Alter, that study's senior author and a scientist
at the University Health Network (UHN) in
Toronto, said in a statement about the findings.
"Our study finds that despite the health-
enhancing benefits of physical activity, this
alone may not be enough to reduce the risk for
disease.”
The American Cancer Society recommends that
people who work at a desk get up to meet with
co-workers instead of emailing, take the stairs
when exiting or entering the office and stretch
periodically. Source: m.livescience.com/51564-sitting-womens-cancer-risk.html |
