Walking and the 2-year risk of functional decline: An observational study of US adults with arthritis

摘要

Recent studies of middle age and older adults with, or at risk for, arthritis demonstrate that engaging in physical activities like walking - even at levels below the current aerobic physical activity guideline of 150 min of moderate-intensity activity - can protect against onset of functional limitations. Using a large nationally representative sample of US adults = 18 years with arthritis, we investigated whether, among those not meeting the aerobic activity guideline, walking = 10 min/week vs. 10 min/week reduced the risk of six outcomes (fair/poor health and five physical limitations) over 2 years.
