Abstract: Using random sampling method from August to September in 2016, 9 body circumferences in adults, including head circumference (HDC), chest circumference(CC), abdomen circumference(AC), hip circumference (HPC), thigh circumference (TC), calf circumference (CFC), upper arm circumference (UAC), forearm circumference (FC), and biceps circumference (BC), from 239 Duerbote Monglian, 404 Fuxin Mongolian, 401 Corlos Mongolian, and 408 Kezuo Mongolian are measured, and the data are compared with that of the other 8 ethnic groups. The results are as followed: (1) The linear correlation analysis showed that there exist significantly negative correlation between some body circumferences with age in the following aspects, such as, the TC, CFC, UAC, BC and FC in the four ethnic groups in the three northeast provinces, the HDC and HC of Duerbote Mongolian and Gorlos Mongolian, femal TC of the four ethnic groups, and the CFC of Duerbote Mongolian, Kazuo Mongolian and Gorlos Mongolian. And there exists significantly positive correlation between some body circumferences with age in the following aspects, such as, female AC of the four Mongolian ethnic groups, and the CC of Fuxin Mongolian, Kazuo Mongolian and Corlos. (2) u test showed that the difference of male and female’s HDC, CC, AC, CFC, UAC, BC, and FC of the four ethnic groups in the three northeast provinces has statistical significance. These body circumference values of male are higher than that of female. And the HPC, TC of female are higher than that of male. (3) The cluster analysis shows that the body circumference values of the four ethnic groups in the three northeast provinces are very similar to each other, and are similar to that of Mongolian in Qinghai province, while male’s body circumference values of the four ethnic groups are also similar to that of Russians’.

Key words: three northeast provinces, Mongolian, human body measurement, circumferences
