HIV/AIDS in Nigeria: a bibliometric analysis

Abstract

BACKGROUND: Nigeria is home to more people living with HIV than any other country in the world, except South Africa and India-where an estimated 2.9 million [1.7 million - 4.2 million] people were living with the virus in 2005. A systematic assessment of recent HIV/AIDS research output from Nigeria is not available. Without objective information about the current deficiencies and strengths in the HIV research output from Nigeria, it is difficult to plan substantial improvements in HIV/AIDS research that could enhance population health. The aim of this study was to analyse the trends in Nigeria's SCI publications in HIV/AIDS from 1980 to 2006. Special attention was paid to internationally collaborated works that were identified based on the countries of the authors' affiliation. METHODS: A bibliometric analysis regarding Nigerian HIV/AIDS research was conducted in the ISI databases for the period of 1980 to 2006. An attempt was made to identify the patterns of the growth in HIV/AIDS literature, as well as type of document published, authorship, institutional affiliations of authors, and subject content. International collaboration was deemed to exist in an article if any co-author's affiliation was located outside Nigeria. The impact factors in the 2006 Journal Citations Reports Science Edition was arbitrarily adopted to estimate the quality of articles. RESULTS: Nigeria's ISI publications in HIV/AIDS increased from one articles in 1987 to 33 in 2006, and the articles with international collaboration increased from one articles in 1980 to 16 in 2006. Articles with international collaboration appeared in journals with higher impact factors and received more citations. A high pattern of co-authorship was found. Over 85% of the articles were published in collaboration among two or more authors. The USA, as the most important collaborating partner of Nigeria's HIV/AIDS researchers, contributed 30.8% of articles with international collaboration. CONCLUSION: Nigeria has achieved a significant increase in the number of SCI publications and collaborations in HIV literature from 1987 to 2005. There is need to challenge the status, scientists from Nigeria should forge multiple collaborations beyond historical, political, and cultural lines to share knowledge and expertise on HIV/AIDS.
