Area of Science:

  • Digital Health
  • Public Health Interventions
  • Behavioral Science

Background:

  • High physical activity levels are crucial for health, but adherence remains a challenge.
  • Conventional pedometers lack intensity and duration metrics, limiting MVPA promotion.
  • A novel smartphone app was developed to target step cadence and offer financial incentives.

Purpose of the Study:

  • To evaluate the feasibility of a novel smartphone app.
  • To determine if the app can increase users' daily moderate-to-vigorous physical activity (MVPA).

Main Methods:

  • A single-arm, pre-post study design was employed.
  • 15 participants used an app without incentives, followed by an app with incentives.
  • Outcomes included successful challenge attempts, daily steps, distance, and Google Fit "heart points" for MVPA.

Main Results:

  • Successful challenge attempts significantly increased from 0.7 to 5.6 per week (P<.001).
  • A trend towards increased daily steps and distance was observed.
  • Daily "heart points" (MVPA) significantly increased from 12.8 to 22.7 points (P=.02).

Conclusions:

  • The smartphone app, utilizing step cadence goals and financial incentives, appears feasible and effective for increasing daily MVPA.
  • Results motivate a larger, confirmatory study to validate these findings.
  • This digital health approach offers a scalable solution for public health initiatives.
