摘要
目的探讨逐步回归分析用于预测足月胎儿体重的可行性。方法监测了200例孕妇的年龄、孕期体重增加、孕次、产次、孕周、宫高、腹围、胎儿双顶径、股骨长度、羊水平段、胎儿体重、性别(出生后)共12项,胎儿体重为因变量,其余11项为自变量。结果在全部样本参与运算的前提下,起作用的是孕周、腹围、双顶径,精确度可达80%。结论逐步回归分析可以用于预测胎儿体重。
Objective To explore the practicability of application of stepwise regression analysis for predicting the full-term fetal weight.Method Two hundred pregnant age,gestational period weight increased,pregnancy times,puerperal times,pregnancy weeks,uterus height,abdominal girth,biparietal diameter,femoral length,amnioric fluid horizontal,fetal weight,sex were examined,the fetal weight was dependent variable.The others were independent.Result On the premise of all samples attending the arithmetic,the pregnancy weeks,abdominal girth biparietal diameter were effective factors.The degree of accuracy was 80%.Conclusion The application repression of stepwise analysis can predict the fetal weight.
