Abstract: Objective To Compare the difference of blood pressure between Korean-Chinese ethnic and Han ethnic in Heilongjiang province and analyze the relationship of the difference of blood pressure between two races with the related factors. Method Systemic vascular resistance (SVR), blood pressure, and so on were determined by BIOZ.com Cardio Dynamics Monitor in 1247 Hans and 676 Korean-Chinese aged from 19 to 80 living in the same area of China. The lipids and glucose of blood were measured by related biochemistry methods. Data were analyzed by SPSS 16.0 software. Results Ethnic（Han=1，Korean-Chinese=2）was positive correlated with systolic blood pressure（SBP）, diastolic blood pressure（DBP）, triglyceride （TG）, low density lipoprotein (LDL), glucose (GLU), Calcium ( Ca2+）. After adjustment for gender, age and BMI, the average systolic/diastolic blood pressures in Korean-Chinese cohort was 3.73/3.54mmHg higher than those in Han cohort. TG, LDL, GLU and Ca2+ produced effect of -0.5%/0.5%, -36.1%/-61.7%, -74.6%/-83.0% and -71.4/-81.6% on SBP/DBP respectively by single factor regression analysis. Conclusion The difference of blood lipids, glucose and Ca2+ play an important role on difference of the blood pressure between two ethnic.
