The average scores for school function, emotional function, social function and physiological function were (80.16±15.36) points, (73.07±19.85) points, (88.52±14.03) points and (82.65±14.17) points, respectively. Multiple linear regression analysis showed that the negative emotions of ethnic Korean primary and middle school students had a negative association with effect on quality of life (β=-0.24, P<0.01), social support had a positive predictive effect on quality of life (β=0.17, P<0.01), and the interaction between negative emotions and social support played a negative role in quality of life of ethnic Korean primary and middle school students (β =-0.19, P<0.01).@*Conclusion@#The health-related quality of life of ethnic Korean children and adolescents is acceptable. Social support can alleviate negative emotions to reduce the impact of negative emotions on quality of life.
