Objective:
The objective of this scoping review was to explore and synthesize the available literature on health research mentorship in low- and middle-income countries (LMICs).

Introduction:
Research mentorship is broadly considered a useful strategy to improve research capacities and research outputs. Existing literature and guidance on research mentorship have focused on high-income countries and assumed resource-rich environments. Despite the successful endeavors to improve health research capacity in LMICs, the strategies that work best under different circumstances are poorly understood. There is a need to map and understand the evidence on health research mentorship in the context of LMICs.

Inclusion criteria:
Sources that reported existing practices, barriers, and mitigation strategies related to health research mentorship in LMICs were included.

Methods:
We searched for published and unpublished studies and reports written in English, Spanish, or Portuguese. The search strategy was not limited by search dates and the last search was conducted on January 28, 2022. The databases searched included MEDLINE (PubMed), Embase, Web of Science Core Collection, CINAHL (EBSCOhost), Cochrane Database of Systematic Reviews, and JBI Evidence Synthesis. We also searched for gray literature in a selection of websites and digital repositories. The JBI scoping review methodology was used.

Results:
A total of 77 studies and reports were included in the review. The majority of the papers were from Africa (n=28). Others were from Americas (n=7), South East Asia (n=4), East Mediterranean (n=2), and Western Pacific (n=2). The remaining studies were from LMICs that included at least two regional offices. Most of the mentorship projects (n=55) were initiated and funded by institutions from high-income countries. The first authors of 41 papers were primarily affiliated from LMICs. The findings were categorized under a description of research mentorship practices, barriers related to research mentorship, and suggested mitigation strategies. Deliverable-driven training using intensive hands-on mentorship and ongoing peer mentorship programs were some of the non-regular, non-institutionalized approaches used to improve research capacity for junior researchers in LMICs. None of the included papers focused on institutional components of research mentorship in LMICs. The barriers to research mentorship activities in LMICs included lack of clarity on mentorship, cultural variations, unbalanced power dynamics, socio-political influences, language barriers, lack of experienced mentors, and limited local funding. Institutionalizing research mentorship, adapting mentoring methodologies relying on local resources, and addressing and respecting diversity in mentorship programs were among the main strategies identified to effectively implement research mentorship in LMICs.

Conclusions:
Research mentorship initiatives and practices are limited in LMICs. Few available practices are introduced by researchers and research institutions from high-income countries and yet not institutionalized. The identified existing practices, barriers, and facilitators on health research mentorship could help the design, implementation, and evaluation of programs to institutionalize health research mentorship in LMICs.
