Early risk prediction tools for heart and metabolic disease in Africa
Integrated modeLs for Early Risk-prediction in Africa (ILERA) study
This project will see if combining genetic, gene-activity, and lifestyle information improves prediction of who in African communities is most at risk for heart and metabolic conditions.

What this research studies
You would be asked to provide a blood sample and information about your lifestyle and environment so researchers can collect genetic and gene-expression data alongside routine health measures for 13 cardiometabolic indicators. The team will begin with current polygenic risk scores and progressively add predicted transcriptomes, environmental, and lifestyle data to build richer prediction models. They will use data-driven methods that can capture complex, non-linear interactions between genes and environment. The work focuses on African populations to create risk tools that better reflect local genetics and exposures.
Who could benefit from this research
Good fit: Ideal participants are adults from African communities who can provide blood samples and lifestyle/health information and are willing to take part in follow-up for cardiometabolic risk research.
Not a fit: People who do not have African ancestry or who already have advanced cardiometabolic disease are less likely to receive direct benefit from the prediction models developed here.
Why it matters
Potential benefit: If successful, this could give people in African communities earlier and more accurate warnings about cardiometabolic risk so they can get targeted prevention or treatment sooner.
How similar studies have performed: Polygenic risk scores have worked well in European populations but perform poorly in African groups, and adding gene-expression and lifestyle data is a newer approach with some promising but still preliminary results.
