# Beta and Pilot Testing of the Surviving & Thriving Healthy Lifestyle App: A Countermeasure to Firefighters’ Occupational Health Risks

## TL;DR

A health app for firefighters was tested and showed promise in improving physical fitness and mental health.

## Contribution

The study introduces and evaluates a healthy lifestyle app specifically designed for firefighters.

## Key findings

- The app received positive usability feedback from 62% of beta testers.
- Pilot testing showed significant improvements in push-up capacity, pull-ups, and mental health scores.
- BMI and 1.5-mile run times also improved during academy training with the app.

## Abstract

Background: Firefighters face elevated chronic disease risks, and interventions promoting healthier lifestyles are essential for improving their well-being. This study aimed to beta test and further evaluate a healthy lifestyle app (HLS app) for firefighters. Methods: Beta usability testing was conducted with new firefighters after using the app. Pilot testing was conducted in two cohorts, (1) the Connecticut Fire Academy Class A-CCA after graduation and (2) the Connecticut Class B-CCB and Miami-Dade Fire Rescue Academy, during academy training to evaluate the potential efficacy of the HLS app in improving healthy lifestyle behaviors, mental health, and physical fitness over three months of use. Results: Beta testing (n = 93) revealed positive usability feedback, with 62% finding it useful for their health. Pilot testing after graduation (n = 28) was associated with increased push-up capacity (35.6 ± 11.7 vs. 42.9 ± 16.1, p = 0.006) and improved mental health scores. Pilot testing during academy training (n = 90) was associated with improvements in push-up capacity (33.8 ± 10.8 vs. 41 ± 10.6, p < 0.001), pull-ups (7 [4–11] vs. 10.5 [6–14], p < 0.001), 1.5-mile run time (11.96 ± 1.43 vs. 11.26 ± 1.1, p < 0.001), BMI (26.7 [24.3–29.7] vs. 25.95 [24.0–28.8], p < 0.001), and mental health scores. Conclusions: The app was well received and showed potential for improving firefighter health. A randomized controlled trial is needed to rigorously evaluate the effectiveness of the HLS app.
