Too much time sitting watching television, linked to a higher risk of colorectal cancer before the age of 50 | Life

WASHINGTON, Feb. 7 – New international research has revealed that sedentary time sitting on television may increase the risk of colorectal cancer, even in people under 50 years old.

Conducted by a team of American, Chinese, and South Korean researchers, including Harvard Medical School, Harvard TH Chan School of Public Health, and the University of Washington School of Medicine, this new study examined data collected from 89,278 US women participating in the project. Nurses' Health Study II, a long-term American health study, examines the risk factors for major chronic diseases in women.

Researchers focused on the time spent watching women's sedentary television, as well as other sedentary behaviors, to examine the possible link between prolonged sitting and early-stage colorectal cancer diagnosed in women. under 50s.

The results, published in JNCI Cancer Spectrum, showed that more than an hour spent watching television each day was badociated with a 12% increase in colorectal cancer risk compared to those who watched less television, and those who watched more than two hours on television per day were almost 70%. one hundred percent increase in risk.

The conclusions are also valid even after taking into account the body mbad index (BMI) and the physical exercise of women. Even women with no family history of colorectal cancer have shown an increased risk. The researchers also found that the badociation was stronger for rectal cancer than for colon cancer.

Although the sedentary lifestyle is an emerging risk factor for colorectal cancer after the age of 50, until now, its role in early colorectal cancer has not been known, say researchers, who add that their findings are the first to link sedentary behavioral behavior to risk. of this particular cancer in young adults.

"This study can help identify people at high risk and who could benefit more from early detection," said Yin Cao, co-lead author of the study. "The fact that these findings are independent of BMI and physical activity suggests that a sedentary lifestyle may be a distinct risk factor for colorectal cancer at an early stage."

Recent-onset colorectal cancer rates are increasing in the United States and around the world. On the other hand, colorectal cancer rates among seniors have decreased significantly, mainly as a result of cancer screening initiatives. – AFP-Relaxnews
