There’s strong research now showing that being active can reduce your risk of colorectal cancer, but how physical activity affects survivors of this cancer is not as clear. Now comes a study suggesting that being active — both before and after diagnosis —can lengthen survival for colorectal cancer survivors.
Not watching a lot of television — a common measure for sedentary living — was also found to improve survival. Survivors who were watching fewer than two hours a day of TV before diagnosis had a reduced risk of mortality compared to those watching five or more hours of TV a day.
The study was published in the Journal of Clinical Oncology last week.
For pre-diagnosis, study authors used data from approximately 3,800 survivors who were part of the large NIH-AARP Diet and Health Study study. In the mid 1990s, the participants were 50 to 71 years old. They answered questionnaires about how much TV they watched, their activity and other lifestyle habits. Those who had developed colorectal cancer were identified in 2006. Continue reading
We’ve all heard the advice to find ways to be more active during the day: Take the stairs instead of the elevator; park in a spot far away from the store entrance to walk a little farther; or get off the bus one stop early and walk to your destination.
While it is relatively easy to make these changes, do you ever wonder if they really make a meaningful difference for your health? I know I do. I always take the stairs, but it just doesn’t feel as important as putting on my sneakers and heading out the door for a planned brisk walk or run. Turns out it is.
A new study published in the American Journal of Health Promotion reminded me that literally every step I take during the day really does make me healthier.
The study’s results showed that people who met the physical activity guidelines (at least 150 minutes of moderate physical activity per week) had similar health outcomes regardless of whether they achieved it using a structured exercise approach (10 minutes or more of exercise at a time) or an active lifestyle approach (less than 10 minutes of exercise at a time). The authors looked at several positive health outcomes associated with activity, such as total cholesterol, blood pressure, and waist circumference. Continue reading
