Couch potato-ism has already been linked to health conditions like diabetes and obesity -- and now a new study suggests it could increase the risk of chronic kidney disease.
"While this study confirms the growing body of literature that supports a link between lifestyle factors and the development of chronic kidney disease, it also adds to the evidence that simply sitting less may have important health benefits," study researcher Dr. Thomas Yates, M.D., of the University of Leicester, said in a statement.
Chronic kidney disease is a condition where the kidneys aren't able to properly filter blood, which can lead to waste build-up within the body and eventually kidney failure, according to the National Institutes of Health. Known causes of chronic kidney disease include high blood pressure and diabetes.
The new study, published in the American Journal of Kidney Diseases, included 5,650 people between ages 40 and 75, who reported the amount of time they spent sitting and how much exercise they got every day.
The researchers found that women were able to lower their risk of developing chronic kidney disease by sitting fewer hours a day -- their risk fell by more than 30 percent when they cut sitting time from eight hours to three hours daily.
Men also saw a benefit in slashing sitting time from eight to three hours, though their risk decreased less -- by just 15 percent, researchers found.
However, the men were more likely to be able to offset the increased risk of chronic kidney disease by exercising, compared with women, researchers said.
This suggests "traditional moderate-to-vigorous intensity physical activity, such as brisk walking, jogging or running on the treadmill may be more important for men, whereas reducing prolonged periods of sitting time may be more important for women," Yates said in the statement.

It Ups Diabetes Risk
<a href="http://www.huffingtonpost.com/2011/08/05/sitting-too-long-diabetes-risk_n_917220.html" target="_hplink">Back in October,</a> researchers from the University of Missouri published results suggesting that sitting throughout most of the day may put individuals at higher risk for diabetes, obesity and non-alcoholic fatty liver disease -- even if you clear time for daily exercise.
It Increases Your Overall Death Risk
<a href="http://www.huffingtonpost.com/2011/06/24/sitting-too-long-death_n_884152.html" target="_hplink">As HuffPost editor Amanda Chan reported back in June,</a> a study in the <em>American Journal of Epidemiology</em> found that women who sat six or more hours a day were nearly 40 percent more likely to die over a 13-year-stretch than those who sat less than three hours. As for men? Sitting for more than six hours was linked with an 18-percent higher risk of death.
Just A Few Mins (In Front Of the Tube) Takes A Toll
An <a href="http://bjsm.bmj.com/content/early/2011/08/01/bjsm.2011.085662" target="_hplink">August study from the <em>British Journal of Sports Medicine</em></a> found that every hour you sit in front of the TV, you can slash your life expectancy by nearly 22 minutes. And watching the tube for six hours a day? That type of seriously sedentary behavior can cut your life expectancy <a href="http://www.huffingtonpost.com/2011/08/17/1-hour-of-tv-lifespan-22-minutes_n_929321.html" target="_hplink">by five years. </a>
It's Linked With Cancer
<a href="http://vitals.msnbc.msn.com/_news/2011/11/03/8616170-if-youre-sitting-down-you-may-be-increasing-your-cancer-risk" target="_hplink">As MSNBC reported,</a> sitting may be responsible for more than 170,000 cases of cancer yearly -- with breast and colon cancers being the most influenced by rates of physical activity (and inactivity). But according to that article, a little bit of walking can go a long way. "For many of the most common cancers, it seems like something as simple as a brisk walk for 30 minutes a day can help reduce cancer risk," Christine Friedenreich, an epidemiologist with Alberta Health Services <a href="http://vitals.msnbc.msn.com/_news/2011/11/03/8616170-if-youre-sitting-down-you-may-be-increasing-your-cancer-risk" target="_hplink">told MSNBC.</a>

It Could Raise Your Heart Attack Risk
Not too long ago, <a href="http://health.yahoo.net/experts/menshealth/most-dangerous-thing-youll-do-all-day" target="_hplink"><em>Men's Health</em> covered a study</a> in the journal <em>Medicine & Science in Sports & Exercise</em>, in which researchers from Louisiana found that people who sit for the majority of the day are 54 percent more likely to die of a heart attack. <a href="http://health.yahoo.net/experts/menshealth/most-dangerous-thing-youll-do-all-day" target="_hplink">Indeed, the investigators found</a> that sitting was an independent risk factor for serious cardiovascular events.

Yet another study shows sitting too much is simply unhealthy. It found those who sat for more than 11 hours a day were 40 percent more likely to die in the next three years than those who sat less than four hours per day.
