Abstract:

To study the circumference and its variation with age of rural adults of Qinghai salar group. Methods Using random sampling method to measure the circumference of head,chest,abdominal, hip, thigh, calf, biceps, fore-arm, and maximum biceps. The change pattern of circumference values of different age groups was analyzed; The circumference values between Salar nationality and other 17 nationalities in China with cluster analysis were compared. Results The results of variance analysis showed that the male and female circumference values of Qinghai salar had significant variation in various age groups in addition to head circumference. At the same time, the difference between the sexes in the same age group had significant variation except for thigh circumference.A linear correlation analysis showed that with the increase of age,the male circumference of chest, abdominal and hip had a linear regularity increase,and the circumference of thigh, fore-arm,and maximum biceps had a liner regularity decrease. The female circumference of chest, abdominal and hip had a linear regularity increase, and the circumference of tight hand a liner regularity decrease.In addition to the circumference of tight and hip, the other circumference values had statistically significant difference between sexes. Conclusion Circumference values of Qinghai Salar group of rural adults have the features of north type groups of our country,is close to the circumference of the Turkic ethnic groups in the Altai language of the northern ethnic group in China, but it is different from that of the ethnic minorities in southern China.
