Migrant workers' health-related research in Nepal: A bibliometric study

In recent years, the health of migrants has become an important global public health issue. However, less is known about the current status of research activity among Nepalese migrants' health. This study aimed to assess the current status of research activity by analysing published peer review literature on Nepalese migrants' health.

A systematic search of published literature on Nepalese migrant workers' health was conducted in Scopus, Medline, CINAHL, Embase, PsycINFO and Web of Science, and a bibliometric analysis methodology was used. The search of databases retrieved 520 records, and a total of 161 papers were included in the analysis. Bibliometric analyses were performed in R and VoSViewer to create visualisation maps.

The retrieved documents were published in the last three decades, and a total of 533 researchers originating from 24 countries contributed to the literature. A large proportion of papers (n=22) were published in a single year, in 2019, and the number of authors per journal ranged from one to 14. The topmost preferred journals for publications in Nepalese migrants' health were PLoS One (n=9), followed by the Journal of Immigration and Minority Health (n=6). The retrieved articles received 2425 citations, with an average of 15.1 citations per article. The study identified nine overlapping research domains (thematic areas) - infectious disease, non-communicable diseases, health and lifestyle, sexual and reproductive health, access to health services, workplace safety, maternal health, gender-based violence, and health system and policy.

The present bibliometric study fills an analytical gap in the field of migrat's health research in Nepal and provides evidence and insights to advocate the formulation of strategies to promote the migrants' health vulnerabilities often associated with individual-related hazards such as working in 'difficult, dirty, and dangerous (3Ds) working conditions.
