Purpose: The purpose of this study was to investigate the knowledge and attitude on tuberculosis by parents of North Korean refugees’ children. Methods: A descriptive study was conducted. Data were collected from July to November, 2014 in Hanawon and 74 North Korean refugee parents participated in the study. Data were analyzed using the SPSS 21.0. Results: The score for knowledge was 17.72 out of 30 points, for awareness in attitude, 49.34 out of 60 points and for prevention behavior in attitude, 48.39 out of 60 points. There were positive significant correlations among knowledge, attitude and health interest. There was also a significant positive correlation between awareness and prevention behavior in attitude, and between prevention behavior and health interest. Conclusion: North Korean refugee parents showed a low level of knowledge and a negative attitude. The implication of these results is an awareness of the need for education on the causes, transmission and importance of treatment for tuberculosis. This kind of education can guide North Korean refugee parents to obtain correct information and positive attitudes and therefore, be able to effectively practice appropriate health behaviors in tuberculosis management for their children.
