Tanglewood Trail Walking Program in Rural Kentucky 2017

Not Applicable

Completed

Conditions: Dietary Habits

Interventions: Behavioral: walking group led by a community organizer

Registration Number: NCT03495648

Lead Sponsor: Dawn Brewer

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.

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. The Walking Program was held June - Sept 2017. Participants completed questionnaires about fruit and vegetable consumption and physical activity. Participants also provided physical and biological measurements.

Although originally designed to compare data among walkers and non-walkers, the protocol was changed due to participant feasibility. Data were analyzed by comparing "low engagers" - those who walked to the market fewer than three times during the program - or "high engagers" - those who walked three or more times during the program. Data were collected at baseline and 3 months.

The data for years 2019 and 2020 of the Tanglewood to Trail walking program are registered separately in ClinicalTrials.gov.

Arm && Interventions

Group	Intervention	Description
Walking Group (Low Engagers)	walking group led by a community organizer	Subjects will participate in a walking group led by a community organizer as a means to get to a local farmer's market. Low engagers are defined as those participants who walked to the market two or fewer times during the program.
Walking Group (High Engagers)	walking group led by a community organizer	Subjects will participate in a walking group led by a community organizer as a means to get to a local farmer's market. High engagers are defined as those participants who walked to the market three or more times during the program.

Primary Outcome Measures

Name	Time	Method
Change in Carotenoid Levels Over Time	Baseline and 3 months	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.

Secondary Outcome Measures

Name	Time	Method
Understanding of Plant-based Phytonutrients	3 months	Participants will be asked a question demonstrating their understanding of the importance of ingesting plant-based nutrients. Possible answers are yes, no, or not sure. Data will be presented as the number of participants in each group that understood the importance of plant-based nutrients.
Change in HDL Cholesterol	Baseline and 3 months	Subjects' HDL will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant HDL.
Change in Total Cholesterol	Baseline and 3 months	Subjects' total cholesterol will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant total cholesterol.
Change in LDL Cholesterol	Baseline and 3 months	Subjects' LDL will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant LDL.
Change in Self-reported Activity Level	Baseline and 3 months	Subjects' self-reported activity level will be measured as self-reported days of leisure physical activity per week.
Group Cohesion	3 months	Subjects' group cohesion was measured post-intervention using the Physical Activity Group Environment Questionnaire" (also known as PAGE-Q). There are 20 questions, ranked using a Likert Scale with 1 being "strongly disagree" and 9 "strongly agree." Scores range from 20-180; higher scores indicate more social cohesion.
Change in A1c	Baseline and 3 months	Subjects' A1c will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant A1c. Data were collected at baseline and 3 months and the difference will be calculated.
Change in Weight	Baseline and 3 months	Subjects' weight will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant weight.
Change in Self-reported Fruit and Vegetable Intake	Baseline and 3 months	Subjects' self-reported total servings of fruit and vegetable intake per day.
Change in Waist Circumference	Baseline and 3 months	Subjects' waist circumference will be measured to determine if walking combined with a voucher for fruits and vegetables changes participant waist circumference.
Belief in the Benefit of Plant-based Nutrients	3 months	Participants will be asked a question demonstrating their appreciation of plant-based nutrients. Possible answers are yes, no, or not sure. Data will be presented as the number of participants in each group that understood the importance of plant-based nutrients.
Belief in the Preventative Effects of Plant-Based Nutrients	3 months	Participants will be asked a question demonstrating their beliefs of plant-based nutrients. Possible answers are yes, no, or not sure. Data will be presented as the number of participants in each group that understood the importance of plant-based nutrients.
Belief in the Role of Healthy Diet in Protecting Health From Pollutants	3 months	Participants will be asked a question demonstrating their beliefs that a healthy diet might protect health from environmental pollutants. Possible answers are yes, no, or not sure. Data will be presented as the number of participants in each group that understood the importance of a healthy diet.
Knowledge of Which Foods Contain Phytonutrients	3 months	Participants will be asked a question about which foods contain phytonutrients. Possible answers are meat, dairy, plant foods, all foods, or don't know. Data will be presented as the number of participants in each group that correctly identified plant foods.
Knowledge of Environmental Pollutants	3 months	Participants will be asked to identify environmental pollutants from a list. Possible answers are polychlorinated biphenyls (PCBs), mercury, nitrites, all of those, none of those, or don't know. Data will be presented as the number of participants in each group that correctly identified all of those.
