Overview
- Researchers analyzed accelerometer data from about 7,200 U.S. adults in NHANES 2003–2006 with roughly 14 years of mortality follow-up.
- Associations between light activity and lower mortality were significant in CKM stages 2 through 4, whereas stages 0 and 1 were combined due to low death rates.
- Increasing light movement from 90 minutes to two hours per day corresponded to a 2.2% absolute 15-year mortality reduction in stage 2 versus 4.2% in stage 4.
- Light activity was defined as movement that does not leave people out of breath, such as casual walking, household chores, stretching, or yoga.
- Authors and an independent American Heart Association expert cautioned that the study is observational yet noted light movement may be a practical focus for patients unable to do vigorous exercise.
