Given the importance of healthy lifestyle practices to cardiovascular disease (CVD) prevention and the utility of church-based interventions in African-American adults, the investigators developed a theory-informed, strategically-planned, health and wellness intervention with Rochester, Minnesota (MN) and Twin Cities area (Minneapolis, St. Paul, MN) churches with predominately African-American congregations. The objective of the study was to partner with churches to implement a multi-component, health education program through the use of core educational sessions delivered through a digital-application accessible on demand via interactive access on computer tablets and the Internet. The overarching goal was to increase the awareness and critical importance of healthy lifestyles for CVD prevention and provide support for behavior change.

The digital app will include 10 education modules addressing the major CVD risk factors to be delivered on-demand through an innovative, interactive video series. The digital app will also support the multi-media education modules, interactive surveys/quizzes, self-monitoring (diet, physical activity), and social networking (discussion board) functionality.
Diet (fruit/vegetable intake using adaptation of NIH Eating at America's Table Quick Food Scan Screener)
Change in self reported diet
Time frame: 28 weeks post-intervention
Physical activity behavior
Change in self-reported physical activity, reported as minutes per week of moderate to vigorous physical activity
Time frame: 28 weeks post-intervention
Diet self-efficacy (using Self-Efficacy and Eating Habits Survey)
Change from baseline self-efficacy; scale of 1-5; Healthy diet score components include the following: fruits and vegetables, ≥4.5 cups/d; fish, 2 or more 3.5-oz servings/wk; fiber-rich whole grains (≥1.1 g fiber/10 g carbohydrate), 3 or more 1-oz-equivalent servings/d; sodium, ≤1500 mg/d; and sugar-sweetened beverages, ≤450 kcal/wk. Dietary recommendations are scaled according to a 2000-kcal/d diet.
Time frame: 28 weeks post-intervention
Physical activity self-efficacy (using Self-Efficacy and Exercise Habits Survey)
Change from baseline self-efficacy. Physical activity is reported via the Self-Regulation Scale from Health Beliefs Survey, which includes 10 items, using a 5-point Likert scale (1=never to 5=always) with higher scores indicating higher PA self-regulation
Time frame: 28 weeks post-intervention
Intervention feasibility
Participant retention (goal \>80% of enrolled participants)
Time frame: 28 weeks post-intervention
BMI
Change from baseline BMI
Time frame: 28 weeks post-intervention
Blood Pressure
Change from baseline blood pressure
Time frame: 28 weeks post-intervention
Fasting Cholesterol
Change from baseline cholesterol
Time frame: 28 weeks post-intervention
Fasting glucose
Change from baseline fasting glucose
Time frame: 28 weeks post-intervention
Smoking (using adaptation of Global Adult Tobacco Survey)
Change in self reported smoking status
Time frame: 28 weeks post-intervention
Life's Simple 7 Composite Score
Change from baseline Life's Simple 7 Composite Score; calculated as a composite of each LS7 component by assigning 2 points for ideal, 1 point for intermediate, or 0 points for poor. The total composite score is assessed on a scale of 0 to 14 points. To categorize, scores of 0 to 6 were labeled "poor', 7 to 8 "intermediate" and 9 to 14 "ideal" cardiovascular health.
Time frame: 28 weeks post-intervention
Cardiovascular health knowledge
Change in percent correct from baseline knowledge and attitudes about CVD
Time frame: 28 weeks post-intervention
