Africa’s contributions to dermatology research have been underreported in the literature, prompting our investigation of the number and quality of scholarly output across the continent’s 49 countries. Using Scopus/SciVal, we analyzed publications from 2012 to 2021 and found only 4579 articles with 36,691 citations, indicating limited productivity. A total of 1804 (39.6%) papers, with 23,414 citations, were published with international collaboration.
To evaluate productivity by country, we used four indicators: number of publications, citations, citations per publication, and field-weighted citations impact. Egypt published the most documents (n=1688), followed by South Africa (n=685), Tunisia (n=388), Ethiopia (n=351), Morocco (n=290), Nigeria (n=249), and Kenya (n=206). The countries with the highest citations were Egypt (n=13,667), South Africa (n=8558), Morocco (n=2413), Kenya (n=2197), and Ethiopia (n=2176).
Journal ranking and metrics can indicate research quality, and Scopus categorizes journals into seven groups or quartiles. Of the 4579 African publications, 4267 are in one of the seven quartiles (Q1-Q7). Only 24 (0.56%) and 195 (4.01%) were published in the top 1% (Q1) and top 5% (Q2) of Scopus sources, respectively. The highest number of documents were in Q5 and Q6.
We also analyzed African contributions to the top 10 dermatology journals globally (
Research is crucial for development and productivity growth, but Africa lags behind in investment. In 2011, while worldwide expenditure on research was 1.77% of the total global gross domestic product, Kenya spent only 0.1% and South Africa spent 0.76% of their gross domestic product on research [
African scholars must remain dedicated to addressing their continent’s problems and should consider stepping outside their comfort zones to pursue knowledge, develop long-term partnerships with high-income countries, and use applied research to bring new information to the continent [
