Purpose: This study aims to identify the general characteristics, subjects, and methods of research on the health of North Korean refugees through a systematic literature review.

Methods: A total of 140 studies on health were reviewed using the analytical framework developed by the researchers.

Results: The quantitative research comprised 90.7% of the studies, whereas the qualitative research were 7.9% of them. Approximately 81.4% of those reviewed have publication dates spanning 2006 to 2015. Only 13.6% of the studies were conducted with the approval of an institutional review board. The subjects of studies were psycho-social health (151.8%), behavioral health (28.5%), cognitive health (15.0%), physical health (12.2%), integrated health (7.8%), and spiritual health (2.8%). Within the quantitative studies reviewed, the most commonly used study design was survey research (86.0%). The two sampling methods used most often were convenience sampling (53.5%) and snowball sampling (19.4%), and the most commonly used data-collection method were questionnaires (94.6%). As for the qualitative studies, the most commonly used study design was phenomenology.

Conclusion: The results suggested that the reviewed studies focused on physical health more than psycho-social health, and physiological measurement more than questionnaires. Ethical considerations need to be expanded.
