cardiometabolic disease
The current study examined the acceptability and feasibility of a smartphone-delivered PA intervention for AA women and explored between-group differences for patterns of change in cardiometabolic disease risk outcomes and hypothesized theoretical mediators. Overall, results for the feasibility and acceptability of the intervention were favorable, while also affording insight into how the intervention could be refined prior to implementation of a fully powered RCT. Observed patterns of change in self-reported MVPA and several cardiometabolic disease outcomes, including cardiorespiratory fitness and blood pressure, further demonstrate the promise of our smartphone-delivered PA intervention. These encouraging findings make an important contribution to the limited body of research examining the utility of mHealth approaches in increasing PA and improving cardiometabolic health among AA women.
