• Resumen

  • The purpose of this study was to examine the association between objectively measured physical activity (PA) and balance in a nationally representative sample of U.S. adults 40 years of age and older. Data from the 2003–2004 National Health and Nutrition Examination Survey were used. Physical activity was measured over a 7-day period using accelerometry, and balance was assessed using the Romberg test. Participants completed a questionnaire regarding their subjective views on difficulty with falling in the past 12 months. For every 60-minute increase in light-intensity PA, participants were 10% (p = 0.04) more likely to have functional balance. Similarly, for every 1-minute increase in log-transformed moderate-to-vigorous physical activity, participants were 23% (p = 0.04) more likely to have functional balance. Regular PA, regardless of intensity, may have health benefits for older adults and is associated with functional balance.
