Effectiveness of the Stroke Riskometer Pro app

Changing behaviour to reduce stroke risk using the Stroke RiskometerTM mobile app – a pilot randomised control trial

Stroke is a devastating yet highly preventable disease. There are about 9000 strokes every year in New Zealand, 30% of which are fatal in the first year and a further 70% of survivors are left with some level of disability. There is evidence that modifying health behaviours is feasible, improves health outcomes, reduces healthcare costs and can reduce an individual’s risk of stroke by about 80%.

However, the level of public awareness of stroke, its risk factors, and how to manage them is low, particularly in communities with low socioeconomic status, in ethnic minority groups and in rural areas. In addition, current high-risk CVD prevention strategies do not target people with low to moderate risk of CVD, which is where the majority of strokes and heart attacks arise.

There is accumulating evidence of the feasibility and effectiveness of using mobile technologies for improving health. The increasing burden of stroke suggests that current primary prevention strategies (’business as usual”) are not sufficiently effective. This highlights the need for an accurate and user-friendly tool to enable individuals to evaluate their own stroke risk, motivate them to reduce their risk and have access to the knowledge to manage their risk, with built-in feedback and the ability to monitor progress.


The aim of the study is to conduct a pilot trial to test the efficacy of the Stroke RiskometerTM app as a standalone and add-on tool for health behaviour modification and stroke education for the primary prevention of stroke. In addition, the study will inform on feasibility issues of conducting a full-scale trial, such as recruitment, acceptability of the intervention and sample size calculation for a full-scale trial to evaluate effectiveness of the app-based intervention, including cost-effectiveness evaluation, for the primary prevention of stroke.

  • BRNZ brings together 67 research groups spread all over New Zealand. Our collaborative community-focused approach is unprecedented for research in New Zealand.
  • We are striving to unlock the secrets of the ageing brain and producing a seismic shift in how researchers, clinicians and community groups partner together.
  • Find out more about our interventions and treatments for neurodegenerative disorders of the ageing brain; such as Dementia, Stroke, Parkinson's Disease, Alzheimer's Disease and Huntington's Disease.
  • When we share and collaborate in order to improve health outcomes for older people, the outcome is a healthier and happier New Zealand.
