- Brief Summary
The purpose of this study is to promote healthy weight loss among African American women, age 30 or older, who are pre-diabetic and/or have high blood pressure and who live, work, or worship in select rural communities throughout Alabama and Mississippi. The goal of the study is to help reduce the burden of obesity, diabetes, and high blood pressure for these women and to collect information on the reach, effectiveness, adoption, implementation, maintenance, and cost effectiveness of our two evidence-base weight loss programs.
- Detailed Description
This study leverages two evidence-based interventions (EBIs) that have been culturally-adapted for the target population and have previously achieved clinically-relevant weight loss and other clinical outcomes (educational group weight loss intervention) along with improvements in diet and physical activity (home gardening intervention). Combining these EBIs addresses multiple domains (behavioral, personal environment, sociocultural) and levels (individual, interpersonal, community) of influence on risk factors for obesity and other cardiometabolic diseases prevalent in the Deep South. These interventions, delivered by local lay staff and non-academic partners, have a high potential for sustainability; however, there is a need to further evaluate the external validity and implementation-related barriers and facilitators to maximize reach, adoption and implementation. The investigators will employ a pragmatic, multilevel, cluster-randomized, type 1 hybrid effectiveness-implementation trial. A total of 264 Black women (age ≥ 30 years) with overweight or obesity and pre-diabetic or hypertensive from 12 rural counties (6 Alabama, 6 Mississippi) will receive either the combined educational group weight loss intervention plus a home gardening intervention or the educational group weight loss classes alone. The specific aims are to compare interventions on: (1) primary outcomes related to implementation effectiveness (reach, adoption, maintenance of health behaviors), (2) secondary outcomes on clinical effectiveness, and (3) cost effectiveness. Findings will inform discussions with coalition partners to achieve our long-term goal of widely disseminating and sustaining multi-level interventions to reduce the multiple chronic disease burden and health disparities in the Deep South.

Group Intervention Description Educational Group Weight Loss Classes PLUS Home Gardening Intervention Home Gardening Intervention Participants will receive the educational group weight loss classes PLUS a home gardening intervention. The gardening intervention will be led by local Master Gardeners (MGs) who will help guide participants in setting-up and maintaining their garden. Educational Group Weight Loss Classes Educational Group Weight Loss Classes Participants will participate in a 12-month weight loss program, taught by lay health educators, and designed to promote and encourage healthy weight loss, dietary changes, and increased physical activity. Participants will attend 90-minute sessions weekly for 6 months, bi-weekly for 3 months, and monthly for 3 months. Educational Group Weight Loss Classes PLUS Home Gardening Intervention Educational Group Weight Loss Classes Participants will receive the educational group weight loss classes PLUS a home gardening intervention. The gardening intervention will be led by local Master Gardeners (MGs) who will help guide participants in setting-up and maintaining their garden.
- Primary Outcome Measures
Name Time Method Weight 0, 6, and 12 months Changes in Weight, measured in pounds
Dietary Intake 0, 6, and 12 months Changes in diet, measured using a questionnaire
BMI 0, 6, and 12 months Changes in BMI, calculated as a person's weight in kilograms divided by the square of height in meters
Waist Circumference 0, 6, and 12 months Changes in waist circumference, measured in centimeters
- Secondary Outcome Measures
Name Time Method Cholesterol Levels 0, 6, and 12 months Changes in LDL and HDL values/ratio, collected by finger-stick
Physical Activity 0, 6, and 12 months Changes in physical activity, measured by the Stanford Leisure Time Activity Categorical Item (L-cat).
The L-Cat is categorical and responses range from 1-6 with 1 indicating little to no physical activity, and 6 indicating vigorous activity for 5 or more days a week.Diastolic and Systolic Blood Pressure 0, 6, and 12 months Changes in values over time, using a calibrated automatic sphygmomanometer and following NHLBI protocols
Fasting Glucose 0, 6, and 12 months Changes in glucose readings, collected by finger-stick
Perceived Quality of Life 0, 6, and 12 months Changes in Quality of Life as measured by the EuroQol-5 Dimension survey (EQ-5D-5L). Condition states range from 1-5 with 1 meaning the participant has no problems or symptoms and 5 meaning they have are unable to perform the activity or are extremely impacted by the condition. Self reported health is measured on a 1 to 100 scale with 1 being the worst possible health and 100 being the best possible health.
