Who can participate?
Current Hong Kong Fire Services Department male firefighters aged over 18 years.
What does the study involve?
This will be a randomized control trial study. Participants will be randomly assigned into either control (health promotion pamphlet) or intervention (health promotion pamphlet and education materials through WhatsApp) groups. Healthy eating knowledge was assessed by self-administrative questionnaire and anthropometric measurements were recorded at three different time points.
What are the possible benefits and risks of participating?
The possible benefits are: the findings of this study will be set as a foundation of a bigger research project, which can be lead to a longitudinal study to observe the sustainability of firefighters’ healthy eating habit. There are no possible risks involved in this study.
Where is the study run from?
The Hong Kong Polytechnic University, Hong Kong.
When is the study starting and how long is it expected to run for?
September 2018 to October 2019

| Scientific title | A feasibility study of a WhatsApp-delivered transtheoretical model-based intervention to promote healthy eating knowledge and habits for firefighters in Hong Kong: A cluster randomized controlled trial |
| Study acronym | HPPEHK |
| Study hypothesis | Using the combination of WhatsApp and pamphlets is better than pamphlets alone in promoting healthy eating habit. |
| Ethics approval(s) | Approved 13/08/2018, Human Subjects Ethics Sub-committee (HSESC) of the Hong Kong Polytechnic University (Room Z404, 4/F, Block Z, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong; cherrie.mok@polyu.edu.hk; 852 2766 6378), ref: HSEARS20180527001-01 |
| Condition | Obesity and cardiovascular diseases |
| Intervention | All participants are the firefighting teams’ member of the Hong Kong Fire Services Department (HKFSD) and they come from more than one fire stations, which located in different districts in Hong Kong. Each fire station may consist of more than one firefighting teams. Each fire station will be treated as individual cluster and randomly assigned into either intervention or control groups using computer generated random numbers. Participants in the control group will receive the stage-based promotion pamphlet at the baseline; whereas the participants in intervention group will receive both stage-based promotion pamphlet (same as the control group) and baseline stage-matched teaching material every two weeks by WhatsApp. Data includes anthropometric measurements (such as body height, body weight, waist circumference, hip circumference), demographic information (such as age, education level, marital status), working characteristics, eating habits, perception on healthy eating promotion programme, stage of change, decisional balance and self-efficacy. Anthropometric measurements will be recorded by a well-trained researcher using same set of measuring instruments throughout the measuring process. Other data will be collected using self-administrative questionnaire. Data will be collected in either University laboratory or fire stations at three different time points: T0 (Baseline), T1 (three months after the completion of 8-week intervention), and T2 (three months after T1). Firefighters’ characteristics and their eating habit are collected at three time points: baseline, T0, 3-months after the completion of 8-weeks intervention, T1 and 3-months after T1, T2. The effects of health promotional program on firefighters’ eating habit and health knowledge will be assessed by comparing the outcomes within individual groups at different time points. Furthermore, comparison between intervention (WhatsApp and pamphlets) and control (pamphlets) groups will also conducted. |

| Primary outcome measure | Eating habit will be assessed using self-administrative questionnaire, which developed on the basis of the Promoting Healthy Lifestyles: Alternative Models’ Effects (PHLAME). Data will be collected at three timepoints: baseline, T0, 3-months after the 8-weeks intervention, T1 and three months after T1, T2. |
| Secondary outcome measures | 1. Anthropometric measurements (body height, body weight, waist circumference, hip circumference) measured by the researcher at three timepoints (baseline, T0, 3-months after the 8-weeks intervention, T1 and three months after T1, T2) using reliable instruments 2. Demographic information (age, education level, marital status) at baseline |
