【摘要】 本文通过对青藏高原海拔3000—4000米地区藏族、汉族7—18岁青少年1468人第二掌骨长度与身高的调查,探讨了二者的内在联系及规律。结果表明:第二掌骨长度与身高的增长近乎平行趋势,该二者之间存在着较高程度的正相关。第二掌骨长度/身高指数比较恒定,以第二掌骨长度推算身高是简便可行的。更多还原

【Abstract】 The authors have studied the relationship between the length of the second metacarpal bone and the body height in 1468 healthy boys and girls (male of Tibetan 373, female 363; male of Han nationality 368, female 364) of 7 to 18 years old. All of them were born and lived at the altitude of 3000-4000 metres above sea level at the Qinghai Tibet Plateau, China.The results indicate that the growth rate of the length of the second metacarpal bone and the height during adolescence is almost parallel All the correlation coefficients between them are positive (0.44-0.89, P<0.05), most are high (>0.60). Since all the indices between the length of the second metacarpal bone and the height are rather constant, the estimation of the height by measuring the length of the second metacarpal bone is feasible. This article provides the regression equations on estimating the height for the children and adolescent in this region.更多还原
