Healthy lifestyles reduce cancer risk among Chinese adults: research

Maintaining healthy lifestyles can significantly reduce the risk of cancer, with each additional healthy lifestyle factor reducing the risk by 6 percent, according to recent research.

Researchers from the Fuwai Hospital under the Chinese Academy of Medical Sciences evaluated the association between clustering of healthy lifestyle factors and cancer risk based on data collected from more than 100,000 Chinese adults.

By referring to the international report Diet, Nutrition, Physical Activity and Cancer: A Global Perspective and the Dietary guidelines for Chinese residents, researchers listed six healthy lifestyle factors: not smoking, maintaining a healthy weight, adequate physical activity, restricting alcohol consumption, adequate vegetable and fruit consumption and limited red meat consumption.

Participants with six healthy lifestyle factors had a 17 percent lower risk of cancer compared with those with no more than three.

The incidence of overall cancer decreased along with an increasing number of healthy lifestyle factors. Each additional factor was associated with a 6 percent lower risk of cancer.

Approximately 47.4 percent of liver cancer cases and 31.9 percent of colorectal cancer cases were attributed to unhealthy lifestyle factors.

The research also showed that only 4.8 percent of the male participants had all six healthy lifestyle factors and male participants with at least three healthy lifestyle factors were less than 60 percent. Among the male participants, 18.4 percent of cancers were attributed to unhealthy lifestyles, which would have been prevented with healthy ones.

According to Gu Dongfeng, the leading researcher, the research revealed the importance of keeping healthy lifestyles in reducing cancer risk. It also provides a reference for China’s health policies and the promotion of healthy lifestyles to reduce the increasing burden of cancer. The research was published in the journal Cancer.
