Interventions

  • Nature-based Walking — BEHAVIORAL
    All participants will be asked to walk three to five times per week for 30-50 minutes per walk, totaling 150 min/week, at moderate intensity over a 6-week period in a designated nature-based, or 'green', urban environment.
  • Built-environment/Commercial Walking — BEHAVIORAL
    All participants will be asked to walk three to five times per week for 30-50 minutes per walk, totaling 150 min/week, at moderate intensity over a 6-week period in a designated built-environment/commercial, or 'Gray', urban environment.

Study Details

The goal of this randomized crossover trial is to compare the differences in psychological and physiological effects of walking in two different outdoor environments (urban/suburban commercial environments vs. urban/suburban nature areas/preserves) in adults with prediabetes. The main questions it aims to answer are: * Do psychological measures of stress, anxiety, and affect improve more in one type of outdoor environment over the other? * Do physiological measures of stress improve more in one type of outdoor environment over the other? As this is a crossover trial, participants will serve as their own controls. Researchers will compare both the psychological and physiological effects walking in the two types of outdoor environments. Participants will: * Walk 150-minutes per week for six weeks in each of the two outdoor conditions. * Visit the clinic four times, including before and after each six-week walking period. * Collect saliva samples immediately proceeding or following the four clinic visits. * Return to their pre-study level of physical activity for a 5-week washout period between each of the two walking interventions.

Arms

  • Experimental: Nature-based Walking then Built-environment/Commercial Walking
    People with prediabetes randomized to six weeks of nature-based walking followed by a five week washout, and then six weeks of built-environment/commercial-based walking
  • Experimental: Built-environment/Commercial Walking then Nature-based Walking
    People with prediabetes randomized to six weeks of built-environment/commercial-based walking followed by a five week washout, and then six weeks of nature-based walking

Primary Outcome Measure

Measure of Anxiety [ Time Frame: Before and after each of the four assessment walks, which occur in weeks 4, 7, 15, and 18 (weeks 3 and 6 of each 6-week walking intervention). ]
