Researchers from the Imperial College of London believe that men who spend more time in front of the television are more likely to develop colon cancer. In one of the largest research , on the relationship between sedentary lifestyles and the risk of developing bowel cancer, scientists have analyzed data from more than half a million men and women. The results of the study were published in the British Journal of Cancer.
A team of scientists compared the risk of developing colorectal cancer in people with the habit of watching TV every night for several hours at a time, with the same risk for those who watch TV for no more than one hour per day. Over 6 years of observations, colon cancer developed in 2 391 people. It was found that the habit of watching TV for 4 hours significantly increases the risk of developing colon cancer in men. And increased physical activity is associated with a lower risk of developing colon cancer. However, strangely enough, no connection was found between the time spent at the computer screen and the risk of developing bowel cancer. Interestingly, the increased risk of intestinal cancer was exclusively male TV viewers, but this dependence was not found in women.
“Previous studies have shown that watching TV can be associated with other forms of negative health behaviors, such as smoking, drinking alcohol, a tendency to frequent snacks. Meanwhile, it has long been known that these habits can increase the risk of developing bowel cancer, “said one of the authors of the study, Dr Neil Murphy.
“The sedentary lifestyle is uniquely associated with weight gain and more fat in the body. Excess fat can affect the level of hormones and other chemicals that can affect the growth of cells, which can increase the risk of bowel cancer, “commented Professor Linda Bold, an expert on cancer prevention from the Cancer Research UK.
“This study also raised an interesting question for us: why does the time in front of computer monitors not increase the risk of developing bowel cancer? There is an opinion that this difference is caused by a large amount of television advertising of unhealthy food, which provokes people to eat more food while watching TV. It is also interesting that the increased risk of colorectal cancer as a result of prolonged viewing of the TV is only for men, and women – no. Perhaps this is due to the fact that men use more alcohol and unhealthy snacks while watching TV, and also smoke more, “Linda Bold added.
Scientists will need further research to answer questions that have arisen as a result of this scientific work. The authors of the study also recalled that maintaining healthy weight, reducing alcohol consumption, physical activity and dietary nutrition rich in fruits and vegetables, significantly reduce the risk of developing bowel cancer in both men and women.
