The efficacy of a new principle for evaluation of fetal growth has been compared to standard methods in a population of pregnant diabetic women. Methods for projecting fetal weight at birth and determining the deviation of growth from an expected fetal weight increase based on our growth model provided significant information for the detection of fetal growth abnormalities 3 weeks (mean) before delivery. (Large for gestational age: sensitivity, 81%; specificity, 85%. Small for gestational age: sensitivity, 100%; specificity, 98%.) With the exception of two models for estimation of fetal weight based on ultrasound measurements of the fetal head and abdomen only, none of the standard methods gave results that were significantly better than the use of the biparietal diameter against a population standard. The new methods are expected to provide valuable information for the treatment of fetal growth disorders.
在一群患有糖尿病的孕妇中，已将一种评估胎儿生长的新原则的功效与标准方法进行了比较。根据我们的生长模型预测出生时胎儿体重以及确定生长与预期胎儿体重增加的偏差的方法，在分娩前3周（平均）为检测胎儿生长异常提供了重要信息。（大于胎龄：敏感性81%；特异性85%。小于胎龄：敏感性100%；特异性98%。）除了仅基于胎儿头部和腹部超声测量来估计胎儿体重的两种模型外，没有一种标准方法的结果比使用双顶径与群体标准相比显著更好。预计这些新方法将为胎儿生长障碍的治疗提供有价值的信息。
