A Multi-language Smartphone-based Healthy Lifestyle Intervention for Firefighters A Cluster Randomized Controlled Trial

What this Trial Is About

Researchers are evaluating the effects of a smartphone-based Healthy Lifestyle HLS intervention on the mental and physical health of firefighters in Tainan, Taiwan. This cluster randomized controlled trial aims to determine if the Traditional Chinese version of the HLS mobile app can improve firefighters health compared to usual care. The study also seeks to find out whether the intervention can promote a healthier lifestyle and reduce the risk of chronic non-communicable diseases among firefighters. Participants will be randomly assigned to either the intervention group, which uses the Traditional Chinese HLS mobile app designed specifically for firefighters, or the control group, which receives usual care. The intervention period lasts from 3 to 6 months, during which firefighters in the intervention group will use the app to support healthier behaviors. The control group will continue with their standard practices without the app. Throughout the study, firefighters will undergo health and fitness assessments at the start and again 3 to 6 months after the intervention begins. Measurements include blood pressure, depressive symptoms, PTSD symptoms, body mass index, smoking habits, diet patterns, physical activity levels, sitting time, sleep duration and napping frequency, glycated hemoglobin, lipid profiles, C-reactive protein, and physical performance. The study will monitor these outcomes to assess changes in mental and physical health. Safety and progress will be observed through these regular evaluations during the study period.
