摘　　要：目的应用计算机X线成像(computed radiography,CR)测量活体上肢骨及胫腓骨正位片上相关指标,建立适合当代中国四川地区汉族14～18岁人群运用上肢骨及胫腓骨推算身高的数学模型。方法对194例14～18岁四川汉族健康青少年进行左侧肢体上肢骨及胫腓骨正位摄片,测量特定标志点间距离,同时准确测量其身高。通过各项测量指标与身高的线性回归分析建立运用上肢骨及胫腓骨推算青少年身高的回归方程。结果共建立有统计学意义的一元回归方程42个,多元回归方程4个,r为0.689～0.917,身高估计值标准误(SE)为3.075～5.485cm。所有方程均经统计学检验和诊断,具有较好的适用性。结论建立的回归方程适用于中国四川地区汉族14～18岁人群的身高推算,应用CR测量上肢骨及胫腓骨长度推算身高,可以为青少年身高推算、法医学个人识别提供技术支撑。Objective Relative parameters of upper limb bones,tibia and fibula were measured with computed radiography and used to establish the mathematical models for stature estimation of teenagers（from 14 to 18 years old） of Han population in Sichuan Province.Methods The upper limb bones,tibia and fibula of 194 subjects were taken computerized radiography on normal position and were measured the lengths between relative landmarks.The body height of each subject was recorded.Linear regression equations for stature estimation between body height and the lengths of upper limb bones,tibia and fibula were established.Results Forty-two single linear regression equations and 4 multiple regression equations were obtained.The coefficients of correlation（r） were 0.689-0.917 and the standard errors of estimate（SE） were between 3.075 and 5.485 cm.All of the equations were statistically tested and diagnosed with good applicability.Conclusion These equations could be used to estimate the body height of Sichuan Han population aged from 14 to 18.The lengths of the upper limb bones,tibia and fibula measured on the CR films could be useful to stature estimation of the adolescence and the forensic personal identification.
