Abstract: This paper makes a statistical analysis of the data of constitution tests on Bai and Han college students. According to detailed rules and requirements of National Students Constitution and Health Standards, the paper compares the physical constitution and health of Bai and Han nationalities in order to obtain an overall understanding of the health status of college students of different nationalities and of the differences and similarities between them. The research finds that Bai and Han students' standard weight for height is normal with no significant differences in their height (P＞0.05) but great differences in boys' standard weight for height (P＜0.01), which may result from the different constitutions of Bai and Han nationalities. Han boys' weight is close to the upper limit of normal standard weight, indicating that they need more exercises.
