[Methods] By using cluster sampling method, the physical indexes of 1697 students in Yanbian area, Han middle and high school were investigated. The distribution of different obesity types in Korean and Han students in Yanbian area was compared. [Results] The mean values ​​of body mass index of Korean and Han students were 19 78 and 19 73 in male and 20 207 and 0 0 0 9 in female, respectively. There was no significant difference among different ethnic groups. And Ponderal index of Han students were 12 0 3,11 83 and 13 10,12 73 for females respectively. There was no significant difference between males and females in ethnic groups, and females were significantly higher than Han students The average waist circumference / waist circumference of ethnic and Han students were 0 82,077 and 0 75,0 73 respectively in female groups, while that of Korean students was higher than that of Han students. [Conclusion] In the selection of high-risk population due to over-fat and abnormal fat distribution in cardiovascular and cerebro-vascular diseases such as hypertension and stroke, the suitable obesity index should be selected according to the specific conditions
