About

The present study aims to test the efficacy of a multi-level telehealth intervention to Enhance Physical Activity (EPA) in 300 low-income Black and Hispanic/Latino adults. EPA is eight weeks with four weekly, hour-long parts: virtual group exercises, virtual group discussions, individual PA participation, and individual phone check-ins. A control group will receive health education. The specific aims are to: 1) test if physical activity increases significantly more among participants assigned to EPA vs. wait-list controls and 2) test if physical function improves significantly more among participants in EPA vs. controls. An exploratory third aim will test mechanisms of change associated with EPA.

Full description

In the U.S., 77% of Black and 79% of Hispanic/Latino (HLs) adults do not meet physical activity (PA) guidelines to engage in moderate to vigorous PA for 150 minutes each week compared to 73% of White adults. Low PA leads to chronic conditions such as cardiovascular disease, type 2 diabetes, and obesity that result in disability and premature death. For Black and HL adults, low PA compounds predispositions to these conditions. Despite the urgent need to increase PA among Black and HL adults, solutions to increase PA are not tailored to this population. Poverty is more than double for Black (19.5%) and HLs (17%) compared to non-HL White adults (8.2%) and meeting PA standards increases with income. Lack of access to costly exercise facilities and living in unsafe neighborhoods contribute to low PA among Black and HL adults. As an alternative to traditional approaches, virtual guidance (i.e., telehealth) is a feasible and effective way to overcome the lack of access to facilities and PA participation in unsafe environments. The present study aims to test the efficacy of a multi-level telehealth intervention to Enhance Physical Activity (EPA) in 300 low-income Black and HLs. This full-scale, well-powered efficacy study builds on a Phase 1 pilot-controlled trial of EPA that showed high feasibility and acceptability in low-income Black and HLs. EPA is eight weeks with four weekly, hour-long parts: virtual group exercises, virtual group discussions, individual PA participation, and individual phone check-ins. Using a socio-ecological model of behavior change, EPA addresses PA and physical function at both intrapersonal (individual PA participation and individual phone check-ins) and interpersonal (virtual group exercises and virtual group discussions) levels. A control group will receive health education with the option to receive EPA later. All participants will attend four visits: pre-test, post-test 1 after EPA, post-test 2 (6 months after post-test 1), and post-test 3 (12 months after post-test 1). EPA is unique compared to other PA interventions as it combines standard PA intervention components with factors vital for increasing PA in Black and HLs while leveraging social connection: culturally relevant support, group discussions targeting discrimination, a telehealth format accessible to low-income people, and activities using everyday items or body weight to account for lack of equipment. The specific aims are to: 1) test if PA increases significantly more among participants assigned to EPA vs. wait-list controls and 2) test if physical function improves significantly more among participants in EPA vs. controls. An exploratory aim is to test mechanisms of change associated with EPA. Based on the sociocultural component of the National Institute on Minority Health and Health Disparities Research Framework, we hypothesize that social connection will mediate PA and physical function outcomes for those who receive the EPA intervention. This research can elucidate behavioral mechanisms responsible for low PA in low-income Black and HL adults and lead to scalable and sustainable multi-level interventions to support increased PA for Black and HL communities.
