Trending Topics pieces (Article Analyses, Evidence Clips and Other Topics) are published in timely response to recent media and journal articles, position statements, clinical guidelines, etc. Since they are based on the most recent evidence/publications, they may not be consistent with PEN evidence in other PEN content areas. As soon as possible, when this occurs, the PEN content will be reviewed and updated as needed.

The Lancet has just published its second series on physical activity called "Physical Activity 2016: Progress and Challenges" which provides updates on surveillance, research, prevention strategies and policy actions. Included in this freely accessible journal edition, are articles on the cost and economic burden of inactivity (estimated to be 67.5 billion globally in 2013) and the health effects of physical activity and sedentary behaviour. A meta-analysis found that one hour of physical activity is enough to offset eight hours of sitting.
An Article Worthy of Attention
Recent research in mice suggests a link between modifiable lifestyle factors, particularly poor diet and lack of exercise, and the biological processes of aging. The researchers found that the fast food diet caused adverse changes in body weight, body composition, as well as markers of physical and metabolic health. They also found that those mice randomized to exervise did not develop the adverse health markers. See a March 2016 Mayo Clinic news article for more information: Poor Diet, Lack of Exercise Accelerate Onset of Age-related Conditions in Mice. The control diet was a usual healthy lab diet for mice and the intervention diet was four times higher in fat and 10 to 15 times higher in sucrose, saturated fat and cholesterol where the mice on the fast food diet received high fructose corn syrup in the drinking water (42g/L). Keep a watch out for more human research in this area to see if it could have a potential impact on practice.
