245 cases of premature birth were compared from the point of view of frequency of aetiologically significant factors with 200 cases of normal birth. The perinatal progress of these premature and normal births was also followed up. It was possible to obtain statistical confirmation of the connection between prematurity and frequent occurrence of some of these parameters. Prominent amongst these are previous abortions and premature births, cervical insufficiency and malformation of the uterus, multiple pregnancies and anomalous foetal position, also placental insufficiency. Increased mortality and morbidity--including perinatal complications--were recorded at the same time. Knowledge of predisposing factors will in many cases make it possible to recognize in good time when pregnancies may be at risk and give adequate supervision and treatment where appropriate.
从病因学显著因素的发生频率角度，对245例早产病例与200例正常分娩病例进行了比较。还对这些早产和正常分娩的围产期进展情况进行了随访。有可能从统计学上证实早产与其中一些参数的频繁出现之间存在关联。其中突出的因素包括既往流产和早产、宫颈机能不全和子宫畸形、多胎妊娠和胎位异常，还有胎盘功能不全。与此同时，记录到死亡率和发病率增加，包括围产期并发症。了解诱发因素在很多情况下将有助于及时识别哪些妊娠可能处于危险之中，并在适当的时候给予充分的监护和治疗。
