摘　　要：目的:应用超声检测胎儿多项生物学指标,预测出生时体重。材料和方法:超声检测468例晚孕胎儿双顶径、头围、腹围、股骨径、肱骨径和上臂径,分析其与胎儿出生时体重的关系。结果:单指标双顶径、头围、腹围、股骨径、肱骨径、上臂径与体重均有一定的关系,其中腹围、上臂径与体重呈高度正相关(r分别为0.8531、0.8982),引入回归方程预测体重(体重=54.12上臂径+5.19腹围+216.72),临床验证其准确性,绝对误差±280g,平均相对误差3.8%。结论:测量胎儿腹围、上臂径对预测胎儿体重具有良好的实用价值。Purpose： Sing uhrasonographic detection of fetus biological features to predict the child＇s birth. Materials and Methods： The pre-natal biological features in 468 fetus in late pregnancy were examined with ultrasound, such as bi-parietal diameter（ BPD）, head circum-ferenee（HC）, abdomen circumference （AC）, femur length（FL）, humeral length（HL） and upper arm diameter（UAL）. The parameters were correlated with the recorded fetalweight（FW） at birth. Results： Every single prenatal parameter, BPD, HC, AC, FL, HL and UAL was found correlated with FW. Especially, AC and UAL had higher correlation with FW（r =0.8531and 0. 8982）. The FW could be formulated as： FW =54.12 UAL ＋ 5.19 CA ＋ 216.72. An estimated calculation error was ± 280g, with an average comparative difference of 3.8%. Conclusion： It is feasible to predict birth-weight via detecting pre-natal biological parameters with ultrasound.
