AB  - OBJECTIVE: To determine the extent to which physiologic, psychologic, and 
      health-related factors predict 6-minute walk distance (6MWD) in older people. 
      DESIGN: Cross-sectional study. SETTING: Retirement villages. PARTICIPANTS: A 
      total of 515 people between the ages of 62 and 95 years (mean +/- standard 
      deviation, 79.5+/-6.4y) residing in retirement villages in Australia. 
      INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Quantitative tests of 
      vision, strength, peripheral sensation, reaction time, and balance and short 
      Mini-Mental State Examination, Geriatric Depression Scale, Positive and Negative 
      Affect Schedule (PANAS), Medical Outcomes Study 36-Item Short-Form Health Survey 
      (SF-36), and 6MWD. RESULTS: All physiologic, psychologic, and health scores were 
      significantly associated with 6MWD. Multiple regression analysis revealed that 10 
      factors (visual contrast sensitivity, lower-limb strength, simple reaction time, 
      postural sway, maximal balance range, PANAS positive scale score, SF-36 pain 
      score, number of medications used, SF-36 general health subscale score, age) were 
      significant and independent predictors of 6MWD performance. Of these measures, 
      strength, maximal balance range, medication use, and age explained the largest 
      proportions of the variance in 6MWD. The final regression model explained over 
      half (52.5%) of the variance in 6MWD (multiple r=.72). CONCLUSIONS: In older 
      people, 6MWD depends on multiple physiologic, psychologic, and health factors. 
      Thus, 6MWD appears to provide a measure of overall mobility and physical 
      functioning in this population group rather than a specific measure of 
      cardiovascular fitness.
