Protocol for a pilot study of an online (eHealth) intervention to reduce heart disease risk in male taxi drivers
Heart disease is a leading health problem across the UK, and men are particularly vulnerable. Taxi drivers face higher risks due to the demands of their job, which often involves sitting for long periods, shift work, stress, and limited access to healthy food. Researchers at Queen's University Belfast have created 'ManGuard', a mobile app tailored specifically for male taxi drivers. This trial aims to see if the app helps drivers make small, positive lifestyle changes. Participants are placed into one of two groups: one uses the 7-week online programme, and the other receives standard care without the app. Taking part involves basic health checks, including quick finger-prick tests for blood sugar and cholesterol. If successful, this research could lead to practical, flexible ways to support the long-term heart health of professional drivers across the country.

What is this study about?
Heart disease is one of the most common health conditions in the UK, and men are statistically more likely to develop it than women. Taxi drivers are at an even higher risk. Spending long hours behind the wheel makes it difficult to stay physically active or find balanced, healthy meals. Combined with stress and irregular working hours, these daily pressures can significantly affect heart and blood vessel health over time.
To address this, researchers at Queen's University Belfast designed 'ManGuard'. This is an online health programme built specifically to fit around the busy, unpredictable schedules of male taxi drivers. Instead of requiring people to attend classes in person, the programme delivers advice, tips, and motivation directly through a smartphone app.
This pilot trial aims to discover whether the ManGuard app is easy to use and genuinely helpful in encouraging healthier daily habits. By comparing drivers who use the app with drivers who do not, the researchers hope to understand if digital support can lower the risk of heart disease in this hard-working group.
Key takeaways
- Tests an online health programme called ManGuard designed specifically for male taxi drivers.
- Aims to reduce heart disease risk by encouraging more movement and healthier habits.
- Lasts 7 weeks and includes short digital modules you can do on your smartphone.
- Requires simple health checks, including a finger-prick blood test.
- Participation is completely voluntary and free of charge.
Who may be eligible?
This study is open to adult men aged 18 and older who work as taxi drivers in Northern Ireland, whether on a full-time or part-time basis.
Because the programme is delivered digitally, participants must have a smartphone that can download apps, reliable internet access, and a good understanding of English.
Women, people under 18, and individuals who do not drive a taxi in Northern Ireland cannot join the study.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- I am a man aged 18 or over.
- I work as a taxi driver (full-time or part-time) in Northern Ireland.
- I own a smartphone with internet access and can download mobile apps.
- I can comfortably read and understand English.
- I am able to give my informed consent to take part.
What does participation involve?
If you take part, you will first complete initial health checks. These include basic measurements and a quick finger-prick blood test to check your cholesterol and blood sugar levels.
You will then be placed into one of two groups by chance (randomly). One group will receive access to the ManGuard smartphone programme for 7 weeks. This programme includes seven short, interactive modules covering exercise, diet, and lifestyle habits. Two modules are essential, while the other five are optional, letting you focus on what matters most to you. The second group will not use the app during this period, serving as a comparison to see how well the programme works.
There are no medications involved. After the 7-week period, follow-up checks will be carried out to see if your activity levels and health markers have improved.

Common questions
Will taking part interfere with my working hours?
No. The ManGuard programme is designed to be flexible so you can complete the short modules on your smartphone whenever you have free time during your day.
Do I have to take any medication during the trial?
No. This study does not involve any medicines or drugs. It focuses entirely on healthy lifestyle choices and digital advice.
What happens if I am placed in the group without the app?
You will carry on with your normal routine while researchers track your health markers. This comparison is essential for proving whether the app actually makes a difference.
Does it cost anything to use the app?
No, taking part in the trial and using the ManGuard programme is completely free.
Who is organising and funding this research?
The study is run by Queen's University Belfast and funded by the Department for the Economy in Northern Ireland.
