Tanglewood Trail Walking Program in Rural Kentucky 2019

Study Overview
=================
Brief Summary
-----------------
The Tanglewood Trail Walking Program is a well established community health initiative that encourages community members to walk approximately 1 mile to the Whitesburg Farmers Market each Saturday. The study aims to determine if walking to the market with a community health coach results in healthier options being selected at the market when compared to the driving group.

Detailed Description
-----------------
In the summer of 2017, community members of Whitesburg, KY were recruited to join the Tanglewood Trail Walking Program to the Whitesburg farmers market. Each Saturday, participants reported whether or not they walked the 1 mile trail to the farmers market and they reported which fruits and vegetables they purchased. Participants completed questionnaires about fruit and vegetable consumption and physical activity. Participants also provided physical and biological measurements. The ClinicalTrials.gov record for the original trial in 2017 is NCT03495648.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Carotenoid Levels | Subjects' carotenoid status will be measured using a carotenoid Raman Spectroscopy to determine if walking combined with a voucher for fruits and vegetables increases intake in fruits and vegetables as measured by carotenoid status. | 3 months | 
| Self-reported Fruit Intake | Subjects' self-reported fruit intake will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant self-reported fruit intake. | 3 months | 
| Self-reported Vegetable Intake | Subjects' self-reported vegetable intake will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant self-reported vegetable intake. | 3 months |
