依据手足印推算身高体重的可行性研究

目的探讨身高、体重与足迹、手印长宽的关系,有助于利用犯罪现场的手印、足迹推断遗留人的身高与体重。方法通过足迹、手印的捺印和测量,大量地收集样本足迹、手印与身高、体重等数据,借助SPSS数理统计软件,进行一元线性回归分析。结果分别建立了由左右足迹、手印全长、掌宽推算身高与体重的十个一元线性回归方程,并对依据左、右侧指标分别推算结果的可靠性进行比较研究。结论可利用回归法由足迹、手印来推算身高、体重。在左右两侧足迹、手印都可利用的情况下,推断身高时应优先选用右侧;推断体重时应优先选用左侧。

Estimation of stature and avoirdupois by measurement of fingerprints and footprints

Objective To find the correlation between stature,avoirdupois and the length or width of footmark and fingerprint.Method 866 people were investigated by measuring the length and width of their fingerprints and footprints,stature,and avoirdupois.Then all data was input into a computer and analyzed by means of SPSS 11.0.Results The length of the footprints or fingerprints was positively and highly correlative to the stature(;p;<0.001).Four regression equations were established for estimating the stature form the length of the fingerprints and footprints.And six equations were established for avoirdupois from their width.All equations were significant(;p;<0.001).Conclusion These equations can be used to estimate stature or avoirdupois of some people.The estimation of stature according to right fingerprints or footprints is more credible,and the estimation of avoirdupois according to left footprints is more credible.
