Who is telling the story? A systematic review of authorship for infectious disease research conducted in Africa, 1980–2016

Abstract

IntroductionAfrica contributes little to the biomedical literature despite its high burden of infectious diseases. Global health research partnerships aimed at addressing Africa-endemic disease may be polarised. Therefore, we assessed the contribution of researchers in Africa to research on six infectious diseases.MethodsWe reviewed publications on HIV and malaria (2013–2016), tuberculosis (2014–2016), salmonellosis, Ebola haemorrhagic fever and Buruli ulcer disease (1980–2016) conducted in Africa and indexed in the PubMed database using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Papers reporting original research done in Africa with at least one laboratory test performed on biological samples were included. We studied African author proportion and placement per study type, disease, funding, study country and lingua franca.ResultsWe included 1182 of 2871 retrieved articles that met the inclusion criteria. Of these, 1109 (93.2%) had at least one Africa-based author, 552 (49.8%) had an African first author and 41.3% (n=458) an African last author. Papers on salmonellosis and tuberculosis had a higher proportion of African last authors (p<0.001) compared with the other diseases. Most of African first and last authors had an affiliation from an Anglophone country. HIV, malaria, tuberculosis and Ebola had the most extramurally funded studies (≥70%), but less than 10% of the acknowledged funding was from an African funder.ConclusionAfrican researchers are under-represented in first and last authorship positions in papers published from research done in Africa. This calls for greater investment in capacity building and equitable research partnerships at every level of the global health community.

Addressing power imbalances in global health: Pre-Publication Support Services (PREPSS) for authors in low-income and middle-income countries

“…Local author representation decreased if any of the collaborators were from the USA, Canada or Europe and it decreased even further in collaborations with top US universities 1. Another review reported a similar trend in infectious disease research in Africa2 and this pattern has also been reported elsewhere 3…”

“…And, as explored by both Abimbola12 and Mbaye et al in their recent publication,2 solutions valued by a local researcher tend to be qualitatively different than those of a high-income country researcher. Whereas short term, often external solutions are favoured by foreign funding agencies, local citizen researchers favour the organic, internal means that can take more time.…”

Passing the microphone: broadening perspectives by amplifying underrepresented voices

“…Others have highlighted the ongoing effects of the legacy of colonialism in perpetuating power disparities between HIC and LMIC partners (Eichbaum et al 2020 ; Bleakley et al 2008 ; Whitehead 2016 ). This is seen in healthcare research as well as in medical education research (Mbaye et al 2019 ; Canadian Coalition for Public Health Research 2015 ; Taylor 2018 ; The Lancet Global Health 2018 ). In the area of academic global health, Abimbola eloquently summarizes these concerns: “[T]he growing concern about imbalances in authorship are a tangible proxy for concerns about power asymmetries in the production (and benefits) of knowledge in global health.…”

Dreams and dream spaces of West African molecular microbiology

“…The scarcity of true principal investigators in Africa has been lamented by science policymakers, and more recently even by funders (Oyebade 2010; Nature 2005; Mbaye et al . 2019). African ideas are insufficiently pursued because a large proportion of the continent's scientists are unable to articulate, develop scientific careers or commit to research lines, or because they do so through principal investigators elsewhere ( Nature 2005; Ramsay 2001; Droney 2014).…”
