Clinical Trial Summary

African American women have among the highest rates of overweight and obesity and few meet dietary or physical activity guidelines. The investigators seek to develop a new intervention strategy that will help alleviate health disparities, thereby improving quality of life, health care costs, and disease burden. The African American Collaborative Obesity Research Network (AACORN) recommends an eco-social, community-engaged approach to behavior change that is in line with cultural values of interconnectedness and care for others. The purpose of this study is to operationalize the AACORN paradigm to promote improvements in weight status and health through a civic engagement approach. To achieve this, participants will meet in church-based Change Clubs and be led through a 6 month curriculum, which includes both lessons in cardiovascular risk reduction and a civic engagement project. Civic engagement may lead to change in individual health behaviors by increasing self-regulation and self-efficacy. The investigators will measure club members' adherence to the Change Club intervention, defined as average number of sessions attended, retention in the clubs, satisfaction with the Change Club experience and achievement of at least 50% of self-identified benchmarks for community change within 6 months. In addition the investigators will compare anthropometric factors, diet and physical activity behaviors, blood pressure, cardiorespiratory fitness, and psychosocial factors before and after participation in the Change Club intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Adherence		attendance will be monitored throughout the 6-month intervention period
Other	Retention		participant retention will be monitored throughout the 6-month intervention period
Primary	Change in Weight from Pre to Post-Intervention (6 Months)	Body weight will be measured in triplicate to the nearest 0.5 kg using a digital floor scale (Seca 876).	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Diet from Pre to Post-Intervention (6 Months)	Two 24-hour recalls (1 weekday and 1 weekend day) will be collected. Data will be entered into the Nutrition Data System for Research (NDSR). Nutrient and food group calculations will be performed using the NDSR software.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Physical Activity Level from Pre to Post-Intervention (6 Months)	Physical activity levels will be measured objectively using accelerometers (ActiGraph GT3X worn for 7 days) and by self-report (7-Day Physical Activity Recall).	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Blood Pressure from Pre to Post-Intervention (6 Months)	Blood pressure will be measured to the nearest 1mm Hg using a validated automated monitor (Omron HEM-705CP), using American Heart Association guidelines.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Cardiorespiratory Fitness Level from Pre to Post-Intervention (6 Months)	Cardiovascular fitness will be measured using the Rockport 1-mile walk test. Participants will walk a flat, 1-mile course as fast as possible without running. Heart rate will be measured immediately after. VO2max will be estimated from validated formulas using 1-mile walk time, gender, age, body weight, and ending heart rate.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Self-Efficacy from Pre to Post-Intervention (6 Months)	Self-efficacy will be assessed the Weight Efficacy Life-Style Questionnaire (Clark 1991). The exercise self-efficacy scale contains 5 items measuring confidence in ability to exercise under various challenges.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Collective Efficacy from Pre to Post-Intervention (6 Months)	Collective efficacy will be measured using an adapted 8-item Likert style scale (Sampson, Raudebush, & Earls 1997) that examines the extent to which individuals in a neighborhood or community trust and help others.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Percent Body Fat from Pre to Post-Intervention (6 Months)	Percent body fat will be measured by bioelectric impedance using a Tanita TBF-410 Bioelectric Impedance Body Composition Analyzer.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Perceived Stress from Pre to Post-Intervention (6 Months)	Perceived stress will be measured using the validated 14-item Perceived Stress Scale (Cohen 1983).	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Level of Civic Engagement from Pre to Post-Intervention (6 Months)	We will use the Civic Engagement Scale (Doolittle and Faul 2013) to assess civic engagement.	pre-post; participants will be followed for the 6-month intervention period
Secondary	Change in Level of Self-Regulation from Pre to Post-Intervention (6 Months)	Self-regulation will be measured using a scale developed by Saelens et al. (2000) to measure self-regulatory skill usage for exercise and for controlled eating.	pre-post; participants will be followed for the 6-month intervention period
