目的 探讨青海省撒拉族乡村成人围度值的年龄变化特征。 方法 采用随机抽样方法，测量青海省海东市循化撒拉族自治县乡村成人的身高、体重等综合指标及头围、胸围、腰围、臀围、上臂围、上臂最大围、前臂围、大腿围、小腿围9项围度值，分析不同年龄组围度值的变化规律；采用聚类分析法，与我国其他17个族群进行对比。 结果 方差分析结果显示，除头围外，其他指标男、女性在各年龄段之间的差异均具有统计学意义；除大腿围外，其他指标在同一年龄段的不同性别间差异均具有统计学意义；相关分析显示，男性胸围、腰围、臀围与年龄成正相关，大腿围、前臂围、上臂最大围与年龄成负相关。女性胸围、腰围、臀围与年龄显著正相关，大腿围与年龄显著负相关。 结论 撒拉族人身体围度更具有中国北方族群的特征，与中国北方族群中阿尔泰语系突厥语族诸族群的围度接近，而与中国南方少数民族围度特征不同。

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.
