More people sit at work, more disease risk

The more people sit the more they are at risk for chronic diseases even if they had a similar body mass index with those who sat less, U.S. researchers say.

Richard Rosenkranz, assistant professor of human nutrition, at Kansas State University and colleagues examined the associations of sitting time and chronic diseases in middle-aged Australian males.

Rosenkranz, and Emma George and Gregory Kolt, both at the University of Western Sydney, said the study involved 63,048 men ages 45-65 from the Australian state of New South Wales. Study participants reported the presence or absence of various chronic diseases, along with their daily sitting time: categorized as less than 4 hours, 4 to 6 hours, 6 to 8 hours, or more than 8 hours.

Compared with those who reported sitting 4 hours or less per day, those who sat for more than 4 hours per day were significantly more likely to report having a chronic disease such as cancer, diabetes, heart disease and high blood pressure.

The study, published in the International Journal of Behavioral Nutrition and Physical Activity, found those sitting for at least 6 hours were significantly more likely to report having diabetes.

“We saw a steady stair-step increase in risk of chronic diseases the more participants sat,” Rosenkranz said. “The group sitting more than 8 hours clearly had the highest risk.”

The study is relevant to office workers sitting at desks and those sitting for long periods of time such as truck drivers, Rosenkranz said. (UPI)






앉아서 일하면 질병 위험 ↑

같은 체질량지수(BMI)를 가진 사람이더라도 앉아서 일하는 사람이 그렇지 않은 사람보다 만성적 질병에 시달릴 위험이 더 높은 것으로 드러났다.

켄자스주립대학교(Kansas State University) 리처드 로센크란즈(Richard Rosenkranz) 영양학 조교수는 호주 중년 남성들을 상대로 하루동안 앉아 있는 시간과 만성 질병의 상관관계를 조사했다.

연구팀은 45세에서 65세 사이의 호주 남성 63,048명을 하루 평균 앉아 있는 시간 4시간 미만, 4시간에서 6시간 사이, 6시간에서 8시간 사이, 8시간 이상으로 나누었다.

그 결과, 앉아 있는 시간이 더 많으면 많을수록 암, 당뇨병, 심장병, 고혈압 등에 시달릴 확률이 더 증가하는 것으로 밝혀졌다.
