Brief Summary

The purpose of this study is to investigate whether seniors living in neighborhoods that are conducive to walking are more physically active than those living in neighborhoods that are less conducive to walking.

Outcome Measures

Primary Outcomes (5)

• Physical Environment Factors Using Geographic Information Systems [GIS]

  Physical environment factors measured using GIS-derived measures of street connectivity, residential density, and mixed land use in participant block groups and a network buffer around each participant's home. A walkability index was created for a 500 meter street network buffer around participant homes. The walkability index was calculated for each census block group in the regions by summing the z-scores of four macro built environment measures: 1) net residential density, 2) intersection density, 3) retail floor to land area ratio (FAR), and 4) mixed use. A higher scores indicates higher walkability. The minimum value is -4.08 and the maximum value is 12.5.

  at two time points, 6 months apart, which were averaged

• Community Healthy Activities Model Program for Seniors (CHAMPS) Self-reported Walking for Errands

  A self-report physical activity questionnaire that assesses weekly frequency and duration of various activities typically undertaken by midlife and older adults over the prior 4-week period. Self-reported walking for errands is one physical activity item assessed. The measure has been shown to have good test-retest reliability (stability) and construct and concurrent validity, and has been shown to be sensitive to change in a variety of adult populations. It has seven frequency categories (from less than 1 hour a week to 9 or more hours per week). The minimum value is 0 and the maximal value is variable. (See Stewart AL, Mills KM, King AC, et al. CHAMPS Physical Activity Questionnaire for Older Adults: Outcomes for Interventions. Med Sci Sports Exerc, 33:7, 1126-1141, 2001.)

  Assessment at baseline and 6 months, with the data across these two time points averaged to increase outcome stability.

• Accelerometer Measured Physical Activity

  Ambulatory assessment of moderate-to-vigorous physical activity using a validated Actigraph accelerometer. Participants were instructed to wear the accelerometer during waking hours for seven days at each of the two measurement points. The accelerometer was placed over the right hip. Data were cleaned and scored using MeterPlus version 4.0 software.

  Assessment at baseline and 6 months, with the data across these two time points averaged to increase outcome stability.

• Neighborhood Environment for Walkability Survey (NEWS) - Walking and Cycling Facilities in Neighborhood

  The scale is walking/cycling facilities which is a mean of 5 items. The minimum value is 1 and the maximum value is 4. Higher scores indicate an environment that is supportive of walking and cycling which is a better outcome.

  Assessment at baseline and 6 months, with the data across these two time points averaged to increase outcome stability.

• Neighborhood Environment for Walkability Survey (NEWS) - Land Use Mix Access

  The scale is land use mix access which is a mean of 7 items. The minimum value is 1 and the maximum value is 4. Higher scores indicate easier access to services which is indicative of a high walkability environment (i.e., a better outcome).

  Assessment at baseline and 6 months, with the data across these two time points averaged to increase outcome stability.
