Healthy Eating & Active Lifestyles for Diabetes (‘HEAL-D’) is a structured education programme that offers people with African and Caribbean heritage culturally tailored, evidence-based diet and lifestyle self-management education and support for Type 2 diabetes (T2D). HEAL-D has been developed to help tackle inequalities in T2D experienced by African and Caribbean communities in the UK, where T2D is 2-4 times more prevalent, diagnosed around 10 years younger and co-morbidities are more common compared to people of White-European ethnicity. Whilst diet and lifestyle advice is the cornerstone of T2D management, people with African and Caribbean heritage perceive that healthcare professionals lack cultural knowledge and awareness, and structured education programmes offered in primary care have lower participation, higher attrition rates and worse outcomes for minority ethnic groups. HEAL-D has been developed using rigorous co-design methodology, engaging African and Caribbean communities, healthcare professionals, commissioners and community leaders in its development. These co-design methods have ensured that HEAL-D is respectful of, and responsive to, the health beliefs and practices of African and Caribbean adults living with T2D.
