Brief summary
This pilot study investigates the effects of a newly developed 12-week weight management program called "GameDay Ready" (compared to a walking and general health education program) for decreasing body weight among Black men who live in the rural South. The researchers expect to see evidence of greater weight loss among participants randomized to receive the "GameDay Ready" program.
Interventions
GameDay Ready is a 12-week, group-based behavioral weight management program in which participants will meet in-person once per week at a publicly accessible walking track. The GameDay Ready program promotes increasing physical activity, reducing sedentary time, and improving dietary habits through education, behavioral self-monitoring, and goal setting. Each 60-minute intervention session includes a brief educational component followed by a group discussion of weekly progress. Following a short warmup walk, participants engage in group-based competitive physical activities and then a short cooldown walk. Participants then set individual and group-based goals for the upcoming week and discuss strategies for overcoming barriers to achieving goals. The program is sensitive to intersectional influences of gender, race, and rurality on health; and strategies to enhance motivation are threaded throughout the program.
Participants receiving the comparison program will complete a 12-week walking and general health education program. Group sessions meet once per week at a publicly accessible walking track, and each 60-minute session consists of a brief educational component on a health topic followed by walking and socializing during the remainder of the session.

Eligibility
Inclusion criteria
* Self-identified African American or Black American male * 20-70 years of age * BMI 27kg/m2 to ≤50kg/m2 (those with a BMI \>45 will need documented approval by a healthcare provider to participate in the study) * Live in a rural area of South Carolina and have lived in a rural area for at least 1 year * Able to speak and understand English * Willing to be randomized to the intervention or comparison program
Exclusion criteria
* Positive response to any question on the Physical Activity Readiness Questionnaire (PAR-Q) (Participant may be included if approval is provided and documented by a healthcare provider) * Currently participating in another weight loss trial or program or have participated in a trial or program within 6 months prior to starting the intervention * Uncontrolled hypertension (systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 mm Hg), diabetes, or asthma (Participant may be included if approval is provided and documented by a healthcare provider) * Pulmonary disease requiring supplemental oxygen or daily use of short-acting bronchodilators * Any musculoskeletal condition that would preclude meeting recommended levels of moderate-to- vigorous physical activity * Within 30 days prior to participating in the study, have taken prescription or nonprescription medications, herbals, or supplements for weight loss * On special diet for a serious health condition (does not include general dietary advice from a healthcare provider for common risk factors such as hypertension, diabetes, or hyperlipidemia). * Major surgery in the past 6 months * Have undergone weight loss surgery or considering weight loss surgery within the next 6 months * Have been treated for cancer in the past 12 months (other than non-melanoma skin cancer) * Weight loss ≥5% during the past 6 months * Plans to move to another county in the next 6 months * Any other perceived physical or mental health-related condition that would preclude participating in a behavioral program designed to promote weight loss
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body weight | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Participants' body weight will be measured in pounds using a portable, professional-grade scale. Changes in body weight will be compared between the intervention and comparison programs. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Body mass index (BMI) | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Participants' body weight will be measured in pounds using a portable, professional-grade scale, and height will be measured using a portable, professional-grade stadiometer. BMI will be computed as weight (lb) / \[height (in)\]2 x 703. Changes in BMI will be compared between the intervention and comparison programs. |
| Waist circumference (WC) | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Participants' WC will be measured using anthropometric measuring tape. Changes in WC will be compared between the intervention and comparison programs. |
| Blood pressure (BP) | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Participants' systolic and diastolic BP will be measured using an automatic blood pressure machine. Changes in BP will be compared between the intervention and comparison programs. |
| Moderate-to-vigorous physical activity (MVPA) | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Average minutes of MVPA will be measured over 7 consecutive days using research-grade, wrist-worn accelerometers (ActiGraph). Changes in MVPA will be compared between the intervention and comparison programs. |
| Fruit and vegetable consumption | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Fruit and vegetable consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in fruit and vegetable consumption will be compared between the intervention and comparison programs. |
| Added sugar consumption | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Added sugar consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in added sugar consumption will be compared between the intervention and comparison programs. |
| Whole grain consumption | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Whole grain consumption will be measured using the National Cancer Institute's Dietary Screener Questionnaire that was used in the 2009-2010 National Health and Nutrition Examination Survey. Changes in whole grain consumption will be compared between the intervention and comparison programs. |
| Social support for exercise and diet | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Social support for exercise and diet will be measured using validated scales developed by Sallis et al. Changes in social support for exercise and diet will be compared between the intervention and comparison programs. |
| Perceived environmental support for physical activity | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Perceived environmental support for physical activity will be measured using the 33-item Rural Active Living Perceived Environmental Support Scale. Changes in perceived environmental support for physical activity will be compared between the intervention and comparison programs. |
| Motivation for weight loss | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Motivation for weight loss will be measured using an 8-item Weight Control Motivation Scale. Changes in motivation for weight loss will be compared between the intervention and comparison programs. |
| Motivation for healthy eating | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Motivation for healthy eating will be measured using a 15-item scale of the Treatment Self-Regulation Questionnaire. Changes in motivation for healthy eating will be compared between the intervention and comparison programs. |
| Motivation for physical activity | Baseline, post-intervention (12 weeks), and 3 months post-intervention | Motivation for physical activity will be measured using the 24-item Motivation for Exercise Scale. Changes in motivation for physical activity will be compared between the intervention and comparison programs. |
