{Abstract}: BACKGROUND: African American Women (AAW) are at high risk for stress-related cardiometabolic (CM) conditions including obesity, heart disease, and diabetes. Prior interventions lack attention to culturally-nuanced stress phenomena (Superwoman Schema [SWS], contextualized stress, and network stress), which are positively and significantly associated with unhealthy eating and sedentary behavior.
OBJECTIVE: The HARMONY Study is designed to test a culturally tailored mindfulness-based stress management intervention to address SWS, contextualized stress, and network stress as potential barriers to adherence to healthy exercise and eating goals. The study will help AAW build on their strengths to promote cardiometabolic health by enhancing positive reappraisal, self-regulation, and self-efficacy as protective factors against chronic stress-inducing biobehavioral morbidity and mortality risk.
METHODS: This two-arm, randomized-controlled trial will test the effects of two group-based, online interventions. HARMONY 1 includes culturally-tailored exercise and nutrition education. HARMONY 2 includes mindfulness-based stress reduction, exercise, and nutrition education. We aim to recruit 200 AAW ≥ 18 years old with CM risk.
RESULTS: Primary outcomes (actigraphy and carotenoid levels) and secondary outcomes (body composition, inflammatory markers, glucose metabolism, and stress) are being collected at baseline and 4-, 8-, and 12-months post-intervention. Intent-to-treat, data analytic approaches will be used to test group differences for the primary outcomes.
CONCLUSIONS: This study is the first to address culturally-nuanced stress phenomena in AAW (SWS, network stress, and contextualized stress) using culturally-tailored stress management, exercise, and nutrition educational approaches to reduce biobehavioral CM risk among AAW. Quantitative and qualitative results will inform the development of scalable and sustainable CM risk-reduction programming for AAW.
BACKGROUND: The Multiple PIs registered the clinical trial (Identifier: NCT04705779) and reporting of summary results in ClinicalTrials.gov in accordance with the NIH Policy on the Dissemination of NIH-Funded Clinical Trial Information, within the required timelines.
