AB  - PURPOSE: To compare the validity of various physical activity measures with 
      doubly labeled water (DLW)-measured physical activity energy expenditure (PAEE) 
      in free-living older adults. METHODS: Fifty-six adults aged >/=65 yr wore three 
      activity monitors (New Lifestyles pedometer, ActiGraph accelerometer, and a 
      SenseWear (SW) armband) during a 10-d free-living period and completed three 
      different surveys (Yale Physical Activity Survey (YPAS), Community Health 
      Activities Model Program for Seniors (CHAMPS), and a modified Physical Activity 
      Scale for the Elderly (modPASE)). Total energy expenditure was measured using 
      DLW, resting metabolic rate was measured with indirect calorimetry, the thermic 
      effect of food was estimated, and from these, estimates of PAEE were calculated. 
      The degree of linear association between the various measures and PAEE was 
      assessed, as were differences in group PAEE, when estimable by a given measure. 
      RESULTS: All three monitors were significantly correlated with PAEE (r=0.48-0.60, 
      P<0.001). Of the questionnaires, only CHAMPS was significantly correlated with 
      PAEE (r=0.28, P=0.04). Statistical comparison of the correlations suggested that 
      the monitors were superior to YPAS and modPASE. Mean squared errors for all 
      correlations were high, and the median PAEE from the different tools was 
      significantly different from DLW for all but the YPAS and regression-estimated 
      PAEE from the ActiGraph. CONCLUSIONS: Objective devices more appropriately rank 
      PAEE than self-reported instruments in older adults, but absolute estimates of 
      PAEE are not accurate. Given the cost differential and ease of use, pedometers 
      seem most useful in this population when ranking by physical activity level is 
      adequate.
