五种健康行为能减少患肠癌的危险

Adoption¹ of a combination of five key healthy behaviors is associated with a reduction in the risk of developing bowel² cancer. Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke quantified the impact of combined multiple healthy lifestyle behaviors on the risk of developing bowel cancer, and found that this impact is stronger in men than in women. Lead author, Krasimira Aleksandrova, says: "These data provide additional incentive³ to individuals, medical professionals and public health authorities to invest in healthy lifestyle initiatives. Each person can contribute a lot to avoid cancer, the more healthy lifestyle changes, the better."

 

Bowel cancer, also called colorectal cancer, is the second most common cancer in men and the third most common cancer in women worldwide, with 55% cases occurring in developed regions such as North America and Western Europe. Previous studies have identified links between the cancer frequency rates and western lifestyles. However, most research has focused on isolated⁴ lifestyle behaviors, such as eating red meat, while little is known about the combined impact of lifestyle factors beyond their individual effects.

 

The research published in the open access journal BMC Medicine analyzed⁵ the data of 347,237 men and women from 10 countries from the European Prospective⁶ Investigation⁷ into Cancer and Nutrition (EPIC) cohort study using a healthy lifestyle index. Over the 12-year study period, 3,759 cases of bowel cancer were recorded.

 

The healthy lifestyle index was composed by the following lifestyle factors: a healthy weight; low abdominal⁸ fat; participating in regular physical activity; not smoking and limiting alcohol; and a diet high in fruits, vegetables, fish, yoghurt, nuts and seeds, and foods rich in fiber⁹, and low amounts of red and processed meat. For each of the five behaviors, study subjects were assigned one point for having the healthy factor and zero for not having the healthy factor. These points were then summed to generate a cumulative¹⁰ score for each participant.

 

Krasimira Aleksandrova, says: "Our data confirmed that with an increasing number of healthy lifestyle behaviors the risk that a person will have of developing bowel cancer decreases."
