Today, a new study found that replacing even a small amount of that sedentary time with some physical activity could reduce early death for people of all weights and waist sizes. A growing body of research is linking sedentary behavior to cancer risk.
The new analysis, published in American Journal of Clinical Nutrition, used data from over 334,000 people in the European Prospective Investigation into Cancer Nutrition (EPIC) study to determine if overweight, obesity or large waist size would affect whether reducing sedentary behavior improves survival.
The investigators compared rates of mortality over twelve years, between four levels of physical activity (inactive, moderately inactive, moderately active and active) and categorized by BMI and waist size. Continue reading
There’s consistent and solid evidence that physical activity reduces risk of several cancers — such as colorectal and postmenopausal breast. Data is not as strong when it comes to survival but it’s growing, especially for breast and colorectal survivors.
That’s the latest from expert Christine Friedenreich, who led off the presentations about physical activity’s effect on survivorship at our research conference today.
Randomized clinical trials (RCTs) are considered the gold standard of studies, which would compare a random group of survivors who follow an exercise intervention to those not doing it. Currently, we don’t have RCTs but there is observational evidence showing benefits, said Friedenreich.
Exercise may supply its benefits in a number of ways: It may help patients complete their treatment or it could help control harms of the therapy. Animal studies suggest exercise may also help the therapy get to the tumor by improving blood flow.
But can the course of exercise alter the course of the disease? Two major studies highlighted will hopefully provide some answers. One is ALBERTA a major observational study focusing on exercise and breast cancer survivors. Then CHALLENGE is a randomized control trial investigating exercise among colon cancer survivors.
Here’s the guidelines from the American College of Sports Medicine on exercise for survivors.
And here’s the latest on our CUP report that came out this month on survival and breast cancer.
About three of every four adolescents are in front of the TV and the computer beyond what is recommended, with youths who are overweight in front of screens more than their healthy weight peers, according to a new government report.
The National Center for Health Statistics report focused on how much screen time 12 to 15 year olds were getting outside of school, citing high screen times’ link with high blood pressure, cholesterol, and being overweight.
For cancer prevention, AICR recommends limiting sedentary activities. Long amounts of time sitting – such as watching TV – links to overweight and obesity, a cause of eight types of cancers. We wrote about the latest research linking inactivity and cancer risk last month.
