Why It Matters
Africa's over-60 population will triple by 2050, yet geriatric medicine trials are almost nonexistent — the continent is ageing into an evidence vacuum.
The Evidence 138 words · target 156
In the burden-versus-investment landscape of African health research, does the distribution of elderly trials across African nations reveal a systematic research gap? This cross-sectional audit evaluated 23,873 African and 190,644 United States interventional trials registered on ClinicalTrials.gov through April 2026. Investigators computed the rate ratio comparing Africa to other regions as the primary estimand using registry metadata for each nation. Africa hosted 87 elderly trials (0.4% of its portfolio) compared to 4,221 in the United States, yielding a 0.0-fold disparity in per-population investment. Temporal analysis showed 17.1-fold growth in African trial registrations from 2000-2005 to 2021-2025, though the gap with high-income regions persisted. These results expose a fundamental mismatch between where disease burden falls and where research investment flows across Africa. Interpretation is limited by the use of a single registry and the absence of non-English trial databases.
