Prolonged sitting can give you Type 2 diabetes

Prolonged sitting can give you Type 2 diabetes

Sedentary lifestyle is a cause of several lifestyle related diseases and Type 2 diabetes is one of them.

Researchers from Maastricht University found that an extra hour of daily sedentary time such as sitting for long hours, is linked to 22 percent increased risk of developing type 2 diabetes.

The CDC reported that the number of new diabetes cases in the United States rose by 1.4 million in 2014, a rate more than three times that of the early 1980s, but significantly lower than the 1.7 million of 2009.

Frank Hu, a professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health and the principal investigator of the diabetes component of the landmark Nurses Health Study, responded to the CDC that right now, almost 29 million people in the U.S. have diagnosed and undiagnosed diabetes. So that s a huge number. And that large number of diabetes patients will have major implications for health care costs and impose a large burden on the health care system.

The study investigated cross-sectional associations of total amount and patterns of sedentary behaviour with glucose metabolism status and the metabolic syndrome.

Researchers included 2,497 participants from The Maastricht Study who were asked to wear an activPAL accelerometer 24 h/day for 8 consecutive days. They calculated the daily amount of sedentary time, daily number of sedentary breaks and prolonged sedentary bouts, and the average duration of the sedentary bouts. To determine glucose metabolism status, participants underwent an oral glucose tolerance test. Associations of sedentary behaviour variables with glucose metabolism status and the metabolic syndrome were examined.

Overall, 1,395 participants had normal glucose metabolism, 388 had impaired glucose metabolism and 714 had type 2 diabetes. The odds ratio per additional hour of sedentary time was 1.22 for type 2 diabetes and 1.39 for the metabolic syndrome. No significant or only weak associations were seen for the number of sedentary breaks, number of prolonged sedentary bouts or average bout duration with either glucose metabolism status or the metabolic syndrome.

An extra hour of sedentary time was associated with a 22% increased odds for type 2 diabetes and a 39% increased odds for the metabolic syndrome. The pattern in which sedentary time was accumulated was weakly associated with the presence of the metabolic syndrome. These results suggest that sedentary behaviour may play a significant role in the development and prevention of type 2 diabetes, although longitudinal studies are needed to confirm our findings.
