Almost two-thirds of Americans now say we take walks, a figure that has nudged up slightly over the years and may mean more adults are likely to get the recommended amount of exercise, according to a government report released yesterday.
Walkers are almost three times more likely to meet the US physical activity guidelines than non-walkers, the report also found.
The finding bodes well for our health, given that regular physical activity reduces the risk of cancer and other chronic diseases. Yet even with these slight gains, only 48 percent of Americans meet the physical activity recommendations for good health, the report states. Government recommendations say we should be active at least 150 minutes a week at a moderate-intensity, such as brisk walking. (For cancer prevention, AICR recommends at least 30 minutes of daily activity.)
The non-communicable diseases in question? Coronary heart disease, Type 2 diabetes … and cancer. Specifically, breast and colon cancers.
All of us at AICR, who have been working to raise awareness about the link between physical activity and lower cancer risk for many years, welcome these papers. It’s gratifying, given the strong evidence presented in the AICR/WCRF expert report and that continues to mount in the AICR/WCRF Continuous Update Project (CUP), to finally see cancer taking its place alongside heart disease and diabetes on such a high-profile list.
Last year, at the AICR Annual Research Conference, we released estimates of the number of US cancers linked to inactivity. There are several ways to calculate such estimates, and the Lancet team used different statistical methods to arrive at their numbers, but the results are strikingly similar, and make it clearer than ever that being inactive has a major impact on cancer, on par with obesity and smoking.

Worldwide, one in ten cases of both breast cancers and colon cancers is due to a lack of physical activity, with inactivity as much to blame for the major chronic diseases as smoking or obesity, finds a major new report published today in The Lancet.
