科学出版物在科学过程中发挥着重要作用，是知识生产和利用之间的关键联系。过去几十年全世界的科学出版活动表明，非洲大多数国家的出版水平很低。我们试图研究1996年至2005年期间由PubMed索引的文章所代表的不同非洲次区域和个别国家的趋势和贡献。非洲的研究产出高度倾斜；1996年至2005年间，南非、埃及和尼日利亚占据了PubMed收录文章总数的60%。根据人口规模进行调整后，冈比亚、加蓬和博茨瓦纳等小国的生产率高于尼日利亚和肯尼亚。根据国内生产总值调整总产量后，冈比亚和厄立特里亚的记录要好一些。在研究期间，非洲对全球研究成果的贡献一直很低。在这项研究中，我们发现人口最多、最富裕的国家（如南非、埃及和尼日利亚）的研究产出相应较高；但较小的国家也可以富有成效。我们注意到，1996年至2005年期间，所有非洲分区域的研究论文产量持续增加，趋势令人欣慰。然而，非洲对全球研究产出的贡献是有限的。
Scientific publications play an important role in scientific process providing a key linkage between knowledge production and use. Scientific publishing activity worldwide over the past decades shows that most countries in Africa have low levels of publication. We sought to examine trends and contribution of different Africa subregions and individual countries as represented by the articles indexed by PubMed between 1996 and 2005. Research production in Africa is highly skewed; South Africa, Egypt, and Nigeria make up a striking 60% of the total number of articles indexed by PubMed between 1996 and 2005. When adjusted for population size smaller countries, such as The Gambia, Gabon and Botswana, were more productive than Nigeria and Kenya. The Gambia and Eritrea had better records when total production was adjusted for gross domestic product. The contribution of Africa to global research production was persistently low through the period studied. In this study, we found that most populous and rich countries (such as South Africa, Egypt, and Nigeria) have correspondingly higher research production; but smaller countries can be productive. We noted continuous increases and reassuring trends in the production of research articles from all African subregions during the period 1996 – 2005. However, contribution of Africa to global research production was limited.
