Plain English Summary
Background and study aims
Type 2 diabetes (T2D) is more common, and develops at a younger age, in people of black African and black Caribbean heritage in the UK than in people from white ethnic backgrounds. Diabetes can have serious health consequences e.g. blindness and kidney failure, which affect people’s quality of life and are costly to the healthcare system. One of the most important ways to avoid diabetes complications is to follow a healthy diet and increase physical activity. This study aims to assess a diet and physical activity education and support programme for people of African and Caribbean heritage who have type 2 diabetes to help them manage their condition and avoid diabetes complications. The programme, called ‘Healthy Eating and Active Lifestyles for Diabetes’ (or ‘HEAL-D’), was created with African and Caribbean people with lived diabetes experience to ensure its content is culturally relevant.
Who can participate?
Adults with T2D of black African or black Caribbean heritage.
What does the study involve?
Adults of black African and black Caribbean heritage with type 2 diabetes will be recruited from primary care, through referral to existing diabetes education services, or via community engagement activities. A short information video will be sent to potential participants to explain the study in more detail. A total of 300 people will be recruited over a 10-month period. Those who are eligible and consent to participation will be randomly assigned to one of two groups:
• The intervention group, who will receive the HEAL-D programme.
• The control group, who will receive the usual diabetes education course that is provided by the NHS in their local area.
Participants will decide if they want to attend their course face-to-face or using online video calling facilities. The HEAL-D programme includes eight sessions, each of 2 hrs duration, delivered over a 6-month period. The time commitment of the diabetes education programmes for the control group varies depending on the programme, but is typically 6-12 hours. All participants will undergo measurement of HbA1c, blood lipids, blood pressure, weight, waist circumference and body composition, alongside a range of questionnaire measures (e.g. quality of life, diabetes knowledge) at baseline, before attending their education programme, and 6, 12 and 24 months later. The measurements will be used to assess the effectiveness and the value for money of the HEAL-D programme against current diabetes education programmes. The study will also investigate which parts of HEAL-D are helpful by interviewing a group of participants and the people who delivered HEAL-D, meaning participants may also be offered to take part in an interview or workshop.
What are the possible benefits and risks of participating?
Participants will need to invest time in the study and attend measurement visits for the collection of research data, for which they will receive modest monetary reimbursement. Participants will receive regular health measurements, as well as diabetes information and support that can help to manage diabetes and improve health and wellbeing. In the longer term, the results of this research study will be shared with black African or black Caribbean communities and may improve healthcare treatment for people of black African or black Caribbean heritage.
There are minimal risks associated with the study. During screening or assessment visits, previously unknown conditions may be revealed for which participants may want support. Blood tests can be uncomfortable, but these will be performed by professional staff, with care taken to minimise any discomfort.
Where is the study run from?
The research study will be coordinated by the University of Leicester’s Diabetes Research Centre, with delivery centres in London, Birmingham and Manchester.
When is the study starting and how long is it expected to run for?
August 2023 to July 2027
Who is funding the study?
The National Institute for Health Research (NIHR), Health Technology Assessment programme; Grant/award number: NIHR151372.

| Scientific title | HEAL-D (Healthy Eating & Active Lifestyles for Diabetes): a multicentre, pragmatic randomised controlled trial comparing effectiveness and cost-effectiveness of culturally tailored versus standard diabetes self-management programmes in Black-African and Black-Caribbean adults with type 2 diabetes |
| Study acronym | HEAL-D |
| Study hypothesis | In adults of black African and black Caribbean heritage living with type 2 diabetes, a culturally tailored diabetes self-management education and support programme (‘HEAL-D’) will improve glycaemic control to a greater extent than standard diabetes education programmes at 12 months follow-up. |
| Ethics approval(s) |
Approved 22/04/2024, East Midlands – Leicester South Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 (0)207 104 8193; Leicestersouth.rec@hra.nhs.uk), ref: 24/EM/0079 |
| Condition | Type 2 diabetes |
| Intervention | Intervention group: The HEAL-D programme consists of 16 hours of group-based education and support (eight 2-hr sessions) delivered using face-to-face or online delivery modes. Sessions 1-7 are delivered on a weekly or fortnightly schedule and session 8 is delivered at 6 months. Culturally tailored resources will be used to deliver the curriculum, including diet booklets, portion size guides, interactive games focusing on cultural foods and dishes, and videos including health and motivational messages. HEAL-D will be delivered by a diabetes specialist dietitian (no specified ethnicity), a community trainer of black African or black Caribbean ethnicity and exercise instructors (no specified ethnicity). Sessions are scheduled for daytime, evening, and weekend delivery. Participants are invited to bring a ‘significant other’ but this is not compulsory. HEAL-D face-to-face is delivered in community settings, such as church halls and community centres, aiming for 8-12 patients in each group. HEAL-D online is delivered via a video-conferencing platform, aiming for 6-8 patients in a group. Control group: Participants allocated to the control arm will receive the standard NHS diabetes education course that is delivered in their local area at the time of the study. They will be offered the choice of attending face-to-face or online virtual delivery where both modalities are offered. Randomisation will be performed by an appropriate delegated member of staff using a validated web-based system. Randomisation will use randomly permuted blocks of variable block length and be stratified by centre, accounting for the provision of different standard education programmes between centres, and baseline HbA1c (<53, 53-76, 77-100 mmol/mol). Allocation will be assigned in a 1:1 ratio to one of the two study arms. Following randomisation, participants will attend their allocated course within 4 weeks where possible and time from randomisation to attendance will be recorded. |

| Publication and dissemination plan | Results will be disseminated to all relevant groups via diverse means. Ongoing review and revision of our dissemination strategy will be undertaken throughout the programme, in partnership with patient and public involvement and engagement (PPIE) partners, to maximise impact and ensure relevance and accessibility to a wide range of groups. We will directly inform commissioners of diabetes education services and Integrated Care Boards, who commission T2D services, to extend commissioning beyond London. We will build on existing relations and in our partner centres to enable us to disseminate our work to decision-makers such as NHS England and the Office for Health Improvement and Disparities. We aim to publish the full results in high-impact medical journals and conferences, with the intention of reaching a global audience. |
