In conclusion, metabolomics is a promising approach for the assessment of biological age and appears complementary to established epigenetic clocks. Sedentary Behavior Raises the Risk of Cancer Mortality https://www.fightaging.org/archives/2020/06/sedentary-behavior-raises-the-risk-of-cancer-mortality/ Living a sedentary lifestyle is known to be harmful to long term health, raising the risk of age-related disease and mortality. Researchers here show that a sedentary life specifically increases cancer mortality, and does so independently of other factors. This is one of many, many reasons to maintain a regular schedule of exercise. In the first study to look at objective measures of sedentary behavior and cancer mortality, researchers found that greater inactivity was independently associated with a higher risk of dying from cancer. The most sedentary individuals had an 82% higher risk of cancer mortality compared to the least sedentary individuals. Researchers also found that replacing 30 minutes of sedentary time with physical activity was associated with a 31% lower risk of cancer death for moderate-intensity activity, such as cycling, and an 8% lower risk of cancer death for light-intensity activity, such as walking. This study involved a cohort of participants from the nationally representative REGARDS study, which recruited more than 30,000 U.S. adults over the age of 45 between 2003 and 2007 to study long-term health outcomes.
