Abstract
Background
Genomic research in dementia in Africa is of utmost importance based on recent reports from studies on African-Americans that the African ancestral gene is associated with a lower risk effect for developing AD. However, dementia-related genetic studies are still evolving in sub-Saharan Africa, with unique challenges influencing participant recruitment.
Objective
This study sought to identify key challenges of recruitment and retention how they were mitigated in the READD-ADSP Africa and ‘Origins of AD in African ancestry’ genetic studies.
Methods
A qualitative narrative research design using in-depth interviews explored the challenges of recruiting participants and how these were managed by the nineteen stakeholders involved in the recruitment process from nine African countries participating in the African Dementia Consortium. An inductive thematic analysis was applied to code and analyze the data systematically.
Results
Nineteen stakeholders from nine African countries, participating in READD-ADSP and ‘Origins’ studies were interviewed. Similar challenges were observed across most African countries, including the non-existing national dementia registry. Other challenges include language diversity, myths around blood collection, family dynamics, stigma, logistics, unmet expectations concerning incentives, fewer older controls and data privacy. Leveraging previous research programs, existing community engagement activities and client-doctor relationships were strategies used in addressing these challenges.
Conclusions
There are some unique challenges with recruiting and retaining participants in genetic studies in Africa. Strengthening community engagement and advocacy for genomic research, alongside a well-populated dementia registry in the African Dementia Consortium, could overcome these challenges and improve participant recruitment in genetic studies.
