About this trial
The goal of this cluster randomized controlled trial is to evaluate the effects of a smartphone-based Healthy Lifestyle (HLS) intervention on firefighters' mental and physical health in firefighters in Tainan, Taiwan. The main questions it aims to answer are:
* Does the Traditional Chinese version of the HLS mobile App improve firefighters' mental and physical health compared to usual care? * Can the intervention effectively promote a healthy lifestyle and reduce the risk of chronic non-communicable diseases among firefighters?
Researchers will compare firefighters receiving the smartphone-based HLS intervention to those receiving usual care to determine whether the intervention leads to improved health and fitness outcomes over 3 to 6 months.
Participants will:
* Use the Traditional Chinese version of the HLS mobile App, originally developed at Cambridge Health Alliance, Harvard Medical School, and adapted for firefighters in Taiwan. * Be randomly assigned to either the intervention group (HLS App) or the control group (usual care). * Undergo health and fitness assessments at baseline and at 3 to 6 months post-intervention.
Anticipated outcomes are improvements in mental and physical health among firefighters receiving the intervention compared to the control group.

Trial outcomes
Primary outcomes
1
Blood Pressure
The participants will maintain a quiet sitting posture for at least five minutes, and the measurement will be taken on a healthy arm without any prior surgery or disease. The blood pressure measuring device will be calibrated and will automatically take three measurements, with a one-minute interval between each. The average blood pressure value will be recorded.
Time frame
3 to 6 months after the intervention starts2
Depressive Symptoms
The participants will be asked to complete questionnaires measuring depressive symptoms, which includes the Beck Depression Inventory for Primary Care (BDI-PC) and the Patient Health Questionnaire (PHQ-9). Questions related to self-harm thoughts have been removed from these instruments to eliminate the need for further referrals. Higher scores indicate greater depressive symptoms.
Time frame
Before the intervention and 3 to 6 months after the intervention starts3
Posttraumatic Stress Disorder Symptoms
The participants will be asked to complete a Posttraumatic Stress Disorder Checklist (PCL-5) questionnaire which measures posttraumatic stress disorder symptoms. Questions related to self-harm thoughts have been removed from these instruments to eliminate the need for further referrals. Higher scores indicate greater depressive symptoms.
Time frame
Before the intervention and 3 to 6 months after the intervention starts4
Body Mass Index (BMI)
The body mass index (BMI) will be calculated by dividing the weight in kilograms by the square of the height in meters. The height will be self-reported before the intervention and measured to the nearest 0.1 cm while standing upright using a tape measure 3 to 6 months post-intervention, and the weight will be self-reported before the intervention, and measured to the nearest 0.1 kg with a weighing scale 3 to 6 months post-intervention.
Time frame
Before the intervention and 3 to 6 months after the intervention startsSecondary outcomes

NT-proBNP
Biochemical parameters will be measured by the Cobas h 232 blood testing system (F. Hoffmann-La Roche AG, Basel, Switzerland) with the fingertip blood of participants with hypertension.
