Feasibility of a large language model-powered health coach integrated with wearable data for lifestyle modifications in young adults

Background

The rising prevalence of non-communicable chronic diseases (NCDs) poses a significant public health challenge worldwide. Unhealthy lifestyle behaviours, such as dietary choices, physical inactivity, and smoking, are key modifiable risk factors for NCDs. Lifestyle interventions in early adulthood are crucial for primary prevention; however, achieving sustained behavioural change remains challenging due to inadequate support. Health coaching is a person-centred approach that effectively promotes healthier habits and enhances self-management of chronic diseases, but faces scalability challenges. Integrating digital health technologies, such as wearable devices and large language models (LLMs), offers a solution. Wearables provide real-time data, while LLMs can automate coaching, offering personalized advice at scale. Working in synergy, they could enhance data interpretation and provide tailored, contextualised feedback, facilitating sustainable behaviour change. However, research on the impact of LLM-based coaching platforms remains limited, focusing primarily on the quality of coaching outputs rather than health outcomes.

Novelty & Importance

The novelty of this approach lies in integrating LLMs with real-time physiological and behavioural data from wearable devices, offering highly personalized and adaptive health coaching. Previous efforts in health coaching automation have often relied on scripted interactions, limiting their capacity to provide nuanced responses. This study will be the first clinical evaluation of an LLM integrated with wearable data to deliver health coaching aimed at improving physical activity levels among young adults. Successful completion of this study is expected to contribute valuable evidence supporting the larger-scale clinical evaluation of generative AI in medicine.

Aims & Objectives

The primary aim is to determine the feasibility of using LLMs for delivering health coaching interventions to enhance physical activity levels among young adults. Specific objectives include exploring user preferences, developing a personalized LLM health coach, evaluating its feasibility and acceptability, and assessing its effect on health outcomes.

Important Information for International Students

It is the responsibility of the student to apply for their Student Visa.


Please note that the EPSRC DRIVE-Health studentship does not cover the visa application fees or the Immigration Health Surcharge (IHS) required for access to the National Health Service. The IHS is mandatory for anyone entering the UK on a Student Visa and is currently £776 per year for each year of study.

 

Additionally, depending on your chosen project, some nationals may need to apply for an Academic Technology Approval Scheme (ATAS) certificate prior to applying for a visa. The ATAS application process can take up to 3 months and so it is essential that you apply for this early. Please note the following:

 

• If you need to apply for a student visa, you cannot submit your visa application until your ATAS certificate has been issued.

• If you are applying for any other visa, you cannot enrol at King’s and start your programme unless your ATAS certificate has been issued.

• If you apply late, you may not be able to join on the expected entry point and your registration may be postponed
