- Registration Number
- NCT02823379
- Lead Sponsor
- Arizona State University
- Brief Summary
The purpose of this project is to test an 8-month, culturally relevant, Smartphone-delivered PA program to improve and maintain high physical levels and reduce cardiometabolic disease risk among obese AA women.
- Detailed Description
A three-phase study will be used to refine and implement an established theory-based culturally relevant physical activity promotion intervention for obese African American women. Phase 1 (Aim 1a) will include formative research where 25 African American women provide feedback (via 9 focus groups) to further refine the physical activity intervention by specifying the deep structure cultural relevance of the theoretical mediators of self-regulation, self-efficacy, social support, behavioral capability, and outcome expectations.5 Phase 2 will focus on technical development of the refined culturally tailored intervention and 1-month demonstration trial of the Smartphone-delivered physical activity promotion program. Phase 3 (Aims 1b and 1c) will test the intervention and delivery strategy in a two-arm randomized trial where 60 sedentary, obese African American women will receive either the 8-month culturally relevant smartphone-delivered physical activity intervention or a 8-month wellness contact control condition

Group Intervention Description Physical Activity Physical Activity A culturally relevant physical activity promotion program delivered using a Smartphone application. Wellness Contact Control Wellness A wellness contract control condition delivered using a Smartphone application.
- Primary Outcome Measures
Name Time Method Feasibility and acceptability of the Smartphone delivered physical activity program 4-months Feasibility and acceptability will be assessed by examining recruitment, retention, adherence, self-reported treatment acceptance, and participant utilization of the Smartphone application provided by analytic tracking software.
Change in physical activity from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months assessed by ActiGraph accelerometers
- Secondary Outcome Measures
Name Time Method change in Aortic Pulse Wave Velocity from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months A measure of aortic stiffness, will be assessed with SphymocorTM using validated methodology
change in blood pressure from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in serum triglycerides from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in body mass index (BMI) from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in total serum cholesterol from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in serum low-density lipoprotein (LDL) from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in serum insulin from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months measured using Immulite 1000 immunoassay analyzer (Siemens Healthcare Diagnostics)
change in tumor necrosis factor alpha from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in Interleukin 1 beta from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in serum high-density lipoprotein (HDL) from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months change in insulin sensitivity from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months assessed by calculating homeostatic model assessment (HOMA) scores as: glucose (mg/dl) x insulin (μU/ml)/405.
change in cardiorespiratory fitness from baseline to 8-months three assessment periods: baseline, 4-months, and 8-months A modified Balke treadmill protocol will be used to estimate aerobic capacity (VO2peak).
