What this trial studies

This study tests a smartphone-delivered intervention called Smart Walk, aimed at increasing physical activity and reducing the risk of heart disease and type 2 diabetes among African American women. Participants will be randomly assigned to either the Smart Walk intervention or a Fitbit-only comparison group over a 12-month period. The study will evaluate the effectiveness of the intervention in promoting adherence to physical activity guidelines and improving cardiometabolic risk factors. Additionally, it will assess the cost-effectiveness of both interventions and explore the relationship between adherence and outcomes.

Who should consider this trial

Good fit: Ideal candidates are self-reported African American/Black women aged 24-65 who are insufficiently active and have a BMI greater than 30.

Not a fit: Patients who are already sufficiently active or have serious health conditions that prevent participation may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve physical activity levels and reduce the risk of serious health conditions among African American women.

How similar studies have performed: Other studies have shown success with culturally tailored interventions for increasing physical activity, suggesting this approach may be effective.
