Effects of Walking in Greenspace and the Built Environment in Adults With Prediabetes: A Randomized Crossover Trial

Sponsor

University of Minnesota

Enrollment

216 participants

Start Date

Jun 6, 2024

Study Type

INTERVENTIONAL

Summary

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.

Plain Language Summary

Simplified for easier understanding

This study is examining whether walking in a green natural environment (like a park) has different health benefits compared to walking in a built urban environment for adults with prediabetes. **You may be eligible if...** - You are between 25 and 64 years old - You are overweight or obese (BMI between 20 and 41.9) - You have been diagnosed with prediabetes within the past year based on a blood test - You are generally not meeting recommended activity guidelines **You may NOT be eligible if...** - You have uncontrolled heart, metabolic, kidney, or lung disease - You have been treated for cancer in the past 5 years - You have a condition that prevents you from safely walking - You are pregnant or planning to become pregnant Talk to your doctor to see if this trial is right for you.

Interventions

BEHAVIORALNature-based Walking

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.

BEHAVIORALBuilt-environment/Commercial Walking

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.
