在这项研究中，通过 4333 次超声检查确定了胎儿双顶径 (BPD)、腹部横径 (ATD) 和股骨长度的生长率。 胎儿的年龄为7至40孕周。 增长率以 3 周为周期计算，速度曲线以 95% 置信区间绘制。 结果显示了这些变量的生长速度的多相模式，在大约 16 周时出现了共同的速度峰值。 16至28周期间，股骨长度的增长速度下降，而ATD和BPD以相同的恒定速率增长。 从28周到37周，只有ATD保持较高的增长率。 37周后，所有增长率都突然下降。 在所有情况下，生长速度均未发现性别差异。
In this study, fetal growth rates of the biparietal diameter (BPD), abdominal transverse diameter (ATD) and femur length were established from 4333 ultrasound examinations. The age of the fetuses ranged from 7 to 40 gestational weeks. The growth rates were computed by periods of 3 weeks, and the velocity curves were plotted with their 95% confidence interval. Results displayed multiphasic patterns of growth velocity for these variables, with a common peak of velocity at about 16 weeks. Between 16 and 28 weeks, growth velocity of femur length decreased, while the ATD and the BPD grew at the same constant rate. From 28 to 37 weeks, only the ATD maintained a high rate of growth. After 37 weeks, all growth rates decreased abruptly. In all cases, no sex differences in growth velocity were found.
