Objective To study somatotype characteristics in Heilongjiang Oroqen adults.Methods The somatotypes of 157 Oroqen adults (male 75, female 82 cases)were evaluated using the Heath-Carter anthropometric method.Results The mean somatotype in males was endomorphmesomorph category(4.3-5.1-1.7),and was meso-endomorph category(6.3-5.0-0.9) in females. Concentrated distribution of the somatotype appeared in the male and female.They were mainly in meso-endomorph, endomorph-mesomorph and endo-mesorph. Ectomorphy factor of the male was slender and the females had more body fat . The somatotypes of Oroqen males were the same to that of females. Compared with other groups from overseas, the endomorphy factor and mesomorphy factor of somatotypes of the Oroqen were higher and ectomorphy factor was lower . The somatotypes of the male were close with Canadian, and those of the female were close with the US Eskimos and Han nationality in Liaoning, but far from Zhuang and Manus people . Conclusion Oroqen adults have a strong physique，skeletal muscle developed,but their somatotypes are a little overweighted and linearity is relatively poo
