Overview of health research in Greenland from 2001 to 2020

Health research in Greenlanders is challenged by a small population, few dedicated researchers and limited funding. Some research areas have proven impactful but gaps in knowledge are unknown. We aimed to quantify health research in Greenland, providing insights for researchers, policymakers and funding agencies to guide future research.

We identified all peer-reviewed health research publications with the term 'Greenland***' in title or abstract from 2001 to 2020 through the platform entitled The Lens. Our bibliometric analysis included number of publications, publication rate, research types, research topics, citations and author affiliations, as well as funding.

From 2001 to 2020, a total of 640 health research publications concerning Greenland or Greenlanders were identified, with an average annual publication growth rate of 2.9%. The major health research topics studied in Greenland were infectious diseases, environmental health and general health. Several research fields, including rheumatology, nephrology and dermatology among others proved understudied at best. Three Danish universities contributed with 33% of all publications, with the International Journal of Circumpolar Health (N=176, 28%) being the top journal destination. The most productive author had 119 article authorships during the period.

During the past 20 years, Greenland's annual publication rate has been steadily increasing, with an average of 32 articles about health research published each year, which is a higher publication rate than world average. The health research in Greenland is primarily epidemiologic with infectious disease being the most studied research area. Most publications were anchored in Denmark and centred around a few highly productive authors.
