A Multi-language Smartphone-based Healthy Lifestyle Intervention for Firefighters

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

Inclusion Criteria:

• Career firefighters who are older than or equal 20 years old

Exclusion Criteria:

• Career firefighters who are younger than 20 years old
• Firefighters who are retired or are volunteer firefighters.
