Active You: A Novel Exercise Program for African Americans
Feasibility and Acceptability of a Web-based Physical Activity for the Heart (PATH) Intervention Designed to Reduce the Risk of Heart Disease Among Inactive African Americans
Study Overview
Status
Detailed Description
Whereas an inverse dose-response relationship has been established between physical activity (PA) and a host of chronic illnesses, including cardiovascular disease (CVD), most American adults (79%) are physically inactive and do not attain the minimum PA levels recommended by the PA Guidelines for Americans. African Americans (AAs) in particular report very low levels of PA, and have the highest burden of CVD in the United States.To eliminate the prevailing cardiovascular health disparities, there is a critical need for pragmatic and culturally salient interventions that are designed to address barriers to PA that are more problematic for AAs.
Common barriers to PA such as lack of time and low exercise self-efficacy are pervasive in all racial groups. In addition to these barriers, socio-environmental factors, such as unsafe neighborhoods and limited access to fitness facilities play a key role in perpetuating the low levels of PA observed in AAs. To mitigate these barriers, home-based PA interventions delivered via mail, telephone and internet have been developed. Although only a few of these interventions have been tested among AAs, preliminary studies have reported more participation and retention of AAs in home-based PA programs. However, the associated PA outcomes have been minimal, especially in less educated AAs. Low literacy levels and reliance on print-based resources with no cultural appeal are thought to limit the utility of the interventions in AAs. The investigators have previously reported how AAs prefer PA programs that are visual, convenient, fun to engage in, and feature people they can relate to especially in body size, fitness status and age. Other studies have reported similar preferences for PA among AAs, yet there is a paucity of PA interventions that are designed to incorporate these preferences.
To bridge this gap, the investigators have developed a web-based Physical Activity for The Heart (PATH) intervention that leverages openly accessible platforms, such as YouTube, to proffer workout videos that match the reported preferences. Currently, PATH includes 90 workout videos vetted using the FITT principle (frequency, intensity, time, type) and curated on the PATH website in 3 controlled levels of intensity (beginner, intermediate, proficient) to foster gradual progression from low to high intensity PA. The overarching aim of the proposed study is to conduct a pilot randomized controlled trial (RCT) to assess the feasibility and acceptability of the PATH intervention for promoting PA in AAs. The investigators will enroll 30 inactive AAs and randomize them to either treatment (12-wks of PATH) or wait-list control (use a general health handout) group to address the following specific aims:
Aim 1: Assess the feasibility and acceptability of the PATH intervention among inactive AAs. Feasibility will be assessed via 1) number of participants screened for eligibility; 2) percentage eligible; 3) percentage enrolled; 4) percentage retained within each randomized group; and 5) adherence to self-monitoring (Actigraph wear time) and intervention protocol (PATH utilization). Acceptability will be evaluated via a post-intervention survey developed by the study team to appraise the intervention's usability and perceived efficacy for increasing PA.
Aim 2: Describe the trends in PA and CVD risk change from baseline to post-intervention. The primary outcome will be PA and will include objectively measured steps, light PA, and moderate-to-vigorous PA (MVPA). Cardiovascular outcomes will include blood pressure (BP), body fat percentage, body mass index (BMI), glycated hemoglobin (HbA1c) and lipids (LDL, HDL, and total cholesterol). Trends will be summarized as mean within-group changes (with 95% confidence intervals [CIs]).
The proposed research addresses a key driver of cardiovascular health disparities and is innovative in its rigorous testing of the novel PATH intervention for feasibility and acceptability among inactive AAs. Findings from this study will inform the refinement of the PATH intervention to be tested in a full-scale RCT.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PATH Treatment Group
The PATH group will be granted password protected access to one of the 3 PATH levels based on their baseline fitness status.
The intervention is designed to help participants increase their baseline PA via health coaching, self-monitoring and pragmatic workout videos that provide convenient options for overcoming socio-environmental barriers to PA.
|
The web-based Physical Activity for The Heart (PATH) intervention leverages openly accessible platforms, such as YouTube, to proffer workout videos that match the participants preferences.
Currently, PATH includes over 90 workout videos vetted by a team of experts and curated on the PATH website in 3 controlled levels of intensity (beginner, intermediate, proficient) to foster gradual progression from low to high intensity PA in accordance with the FITT-VP (frequency, intensity, time, type, volume, progression) principle.
|
Other: Wait-list control group
Participants in this group will not have access to the PATH intervention until after 12 weeks when they cross over.
After randomization, the control group will be provided with a copy of the Be Active Your Way booklet, developed by the Centers for Disease Control (CDC) to help individuals integrate PA in their daily lives.

Be Active Your Way booklet was developed by the Centers for Disease Control (CDC) to help individuals integrate PA in their daily lives.
It simply encourages individuals to increase their PA gradually and gives them examples of things that they can do.
