About this trial
The goal of this clinical trial is to engage African-American churches via an established community-academic partnership (FAITH! Program) to build capacity to promote cardiovascular health and digital health equity in African-American faith communities. There are 3 study aims:
Aim 1: Co-design a culturally tailored digital health equity toolkit with community members
Aim 2: Train a network of Digital Health Advocates (DHAs) in digital health equity and cardiovascular health promotion
Aim 3: Test the impact of a DHA-enhanced mobile health intervention (the FAITH! App) on cardiovascular health and digital health readiness among participants
In Aim 1, participants will attend a series of focus groups to share their input on a digital health equity curriculum that will be condensed into a toolkit.
In Aim 2, DHAs will be trained using this toolkit as well as a community health advocacy curriculum to learn how to promote digital health readiness and cardiovascular health in their communities.
Finally, Aim 3 will be a randomized controlled trial where participants will use the FAITH! App to improve their cardiovascular health. Some participants will have the added support of a DHA, and the control group participants will use the app with no additional support to test whether the DHA support is associated with a more significant improvement in cardiovascular health.

DHA-Enhanced FAITH! App
BehavioralThis group of participants will follow an 11-week guided intervention with the FAITH! App. Weekly educational modules provide information on components of cardiovascular health (CVH). Participants are given a Fitbit to track physical activity, which will automatically synch to the app and will be asked to track their daily fruit and vegetable intake on the app. DHAs will promote CVH and digital health readiness as peer mentors by guiding participants through the educational modules and encouraging use of the additional interactive app features. During the guided intervention phase, they will facilitate weekly visits with participants in their church, which will follow the FAITH! App modules and integrate a digital health topic. Following the 11-week guided intervention, participants will have a 12-month maintenance phase with access to use the app as they wish.
FAITH! App
BehavioralThis group of participants will follow an 11-week guided intervention with the FAITH! App. Each week, an educational module is completed in the app, which provides information on a component of cardiovascular health. Participants will be given a Fitbit to track their physical activity, which will automatically synch to the app, and will be asked to track their daily fruit and vegetable intake on the app as well. Following the 11-week guided intervention, participants will have a 12-month maintenance phase in which they will have access to use the app as they wish.
Treatment groups
Trial outcomes
Primary outcomes
Life's Essential 8 Composite Score change
Changes from baseline in Life's Essential 8 score. Life's Essential 8 composite score is determined as a composite of all components by calculating an unweighted average score on a scale of 0 to 100 points. An overall cardiovascular health score (Life's Essential 8 score) will be considered high (80 to 100 points), moderate (50 to 79 points) or low for (0 to 49 points).
Blood Pressure Score Change (Life's Essential 8 Component)
Average of 3 sitting measurements of systolic and diastolic pressures (mmHg).
Fasting Glucose/Hemoglobin A1c Score Change (Life's Essential 8 Component)
Fingerstick blood collection (fasting glucose-mg/dL; Hemoglobin A1c-%).
Fasting Blood Lipids Score Change (non-HDL cholesterol) (Life's Essential 8 Component)
Fingerstick blood collection (mg/dL).
Secondary outcomes
Digital Health Readiness
Assessed using a validated, 20-item instrument that captures 5 domains: digital skills, digital usage, digital literacy, digital health literacy, and digital learnability adapted for all digital health technologies such as smartphone apps.
Social Support - Diet
Diet social support measured using the Social Support for Eating Habits Survey scale. This scale assesses the level of encouragement or discouragement from family and friends that participants received for adopting healthier eating habits. 5 questions were asked to assess the degree of encouragement and discouragement, separately, on a 5-point scale \[from 1 (none) to 5 (very often)\]. Each sub-item was summed to obtain a score ranging from 5 (lowest) to 25 (highest discouragement/encouragement). The change in level of diet social support was calculated from baseline to 6 months post-intervention. Higher scores indicate more change in social support for healthy eating.
Self Regulation - Diet
Diet self-regulation measured by the Health Beliefs Survey to assess strategies used in the past 3 months to eat healthier foods. Items are measured on a five-point scale from 1 (never) to 5 (always). A mean of all items is obtained and a difference between the scores is calculated. Higher change in scores indicate more change in use of self-regulation strategies to promote healthy eating.
Perceived Barriers - Diet
Changes from baseline to 12 months post-intervention in diet perceived barriers measured by Barriers to Diet and Exercise questionnaire. The 39-item instrument is measured on a five-point scale from 1 (not at all true for me) to 5 (very true for me); participants indicate the extent to which each factor has made it difficult for them to follow appropriate eating and exercise habits in the past 6 months.
