Purpose: The purpose of this study was to compare exercise performance with related factors between Korean and Korean-Chinese nursing students. Methods: This study used a cross-sectional comparative survey method. One hundred sixty five Korean nursing students in Seoul, South Korea and 161 Korean-Chinese nursing students in Yanbian, China were recruited through convenience sampling. They were at the age of 19-26. Exercise performance and exercise-related factors were measured using the exercise performance degree scale and the scales of self-efficacy, perceived barriers, perceived benefits, and affection related to exercise. Results: No significant difference in exercise performance was seen between the two groups. Self-efficacy and perceived benefits related to exercise performance were significantly higher in the Korean nursing students than in the Korean-Chinese nursing students. However, there were no significant differences in affection and perceived barriers related to exercise. Conclusion: We suggest that the reasons for the differences in self-efficacy and in perceived benefits between these two groups need to be explored though future studies. We suggest more studies comparing different groups having the same ethnicity as Korean but who were born into different societies to give answers regarding the influence of immigrated transition on health.
