【摘要】 目的:探讨广西毛南族中小学生手长、掌长、指长与身高的相关关系,为毛南族儿童青少年身体发育提供参考数据。方法:对广西河池地区6~15岁毛南族中小学生948人(男497人,女451人)手长、掌长、指长、身高进行测量分析。结果:毛南族中小学生14岁前手长、掌长、指长和身高指标男女生间均相差不大,14岁后7项指标均为男生大于女生。手长、掌长、指长与身高各比值变化范围均较小,而且男女生同一比值非常相近。计算出手长、掌长、指长和身高的均数、相关系数及其与身高的比值并推算出预测身高的回归方程。结论:手长、掌长、指长和身高均随年龄增长而增加,手长、掌长、指长与身高的比值随年龄变化不明显,所得的回归方程可用于推算毛南族中小学生的身高,为毛南族人类学、法医学研究提供了一定的参考依据。更多还原

【Abstract】 Objective:To investigate the relationship between height and hand length,metacarpal length and finger length of Maonan students in middle and primary schools in Guangxi and to provide some data on the physical development of children and adolescents from Maonan nationality.Methods:The height,hand length,metacarpal length and finger length of 948(497males 451 females) Maonan students aged 6 —15 years in middle and primary schools were measured and analyzed in Hechi Guangxi.Results:The hand length,metacarpal length,finger length and height of boys and girls of Maonan students in middle and primary schools were not significantly different(P>0.05) before the age of 14,but boys outweighed girls in the 7indicators after 14 years of age(P<0.01).The ratio range of the hand length,metacarpal length,finger length and height was smaller,and the ratio difference between boys and girls were very similar(P>0.05).The mean values of the height,hand length,metacarpal length and finger length,as well as the correlation and the ratio between the height were calculated out The regression equations of calculated height were obtained.Conclusion:The hand length,metacarpal length,finger length and height increase with age;the hand length,metacarpal length and finger length have high correlation with the height and the ratio does not change significantly with age.The regression equations can be used to calculate the height of Maonan students in middle and primary schools,and to provide some data for Maonan nationality anthropology and forensic medicine research.更多还原
