摘　　要：目的应用骨盆髂嵴与坐骨结节骨骺发育状况的X线影像学特征评估四川汉族青少年的生活年龄。方法参照Tw：分级原则，结合本次研究选取的年龄跨度、骨骺发育规律，将髂嵴骨骺发育程度分为8级（0～7级），坐骨结节的骨骺发育程度分为7级（0～6级）。再根据上述分级，对691例四川汉族16。20周岁青少年骨盆X线片进行阅片，运用SPSS19．0软件进行统计学分析，并将年龄（Y）与髂嵴（X1）、坐骨结节（X2）骨骺发育级别作多元线性回归方程。结果双侧髂嵴、坐骨结节骨骺发育差异无统计学意义（P〉0．05），髂嵴、坐骨结节骨骺发育在两性之间差异亦无统计学意义（P〉0．05）。多元回归方程为y=15．269＋0．444X．＋0．236X2，样本回代检验表明该方程准确性较高。结论通过髂嵴、坐骨结节骨骺发育程度的多元回归方程进行骨龄评估，可以为四川汉族人口进行18周岁的年龄评估提供科学依据。Objective To estimate the chronological age of Han teenagers in Sichuan by the epiphyses development characteristics of iliac crest and ischial tuberosity in X-ray digital images. Methods Accord- ing to TW2 classification principle, combining with the age range of our subjects and epiphyses develop- ment regularity, the degree of epiphyses development of iliac crest and ischial tuberosity had been divid- ed into 8 grades （0-7） and 7 grades （0-6）, respectively. Based on the degrees, the pelvic X-rays digital images of 691 samples of 16-20 aged teenagers were read and statistically analyzed by SPSS 19.0 soft- ware. The multiple linear regression equation was established by skeletal age （Y）, development degree of iliac crest epiphyses （X1） and ischial tuberosity epiphyses （X2）. Results There were no statistical dif- ferences between two sides of epiphyses development of iliac crest and ischial tuberosity （P〉0.05）. There were no statistical difference between genders （P〉0.05）. The re-substitution method of the samples showed that the accuracy of equation as Y=15.269＋O.444XI＋0.236 X2 was high. The result of the re-substitution method showed a high accuracy of the equation. Conclusion The multiple linear regression equation could be used to identify the skeletal age for providing the scientific basis to identify the 18-year-old Han population in Sichuan.
