In a population sample, whose congruity with the country-wide population was verified, the birthweight, menstrual age and gestational age (assessed by repeated ultrasonic foetometry in the course of pregnancy) were mutually correlated. A group of 80% of newborns out of the total population sample, in whom no disturbance of foetal growth rate was found throughout the course pregnancy, served as the basis for preparation of the standard of normal foetal growth. In the interval from the 36th to the 42nd week of pregnancy a highly significant linear relationship between gestational age and birthweight was found, without terminal flattening of the "normal foetal growth curve". In the remaining 20% of the population there was a twofold predominance of growth retardation over growth acceleration.
在一个经核实与全国人口具有一致性的人群样本中，出生体重、月经龄和孕龄（通过孕期多次超声胎儿测量评估）相互关联。从总人口样本中选取80%的新生儿作为正常胎儿生长标准的制定依据，这些新生儿在整个孕期均未发现胎儿生长速率紊乱。在妊娠第36周到第42周期间，发现孕龄与出生体重之间存在高度显著的线性关系，“正常胎儿生长曲线”没有末端变平。在其余20%的人群中，生长迟缓的发生率是生长加速的两倍。
