在排除死产、多胞胎、所有已引产的职业以及所有妊娠时长不确定的职业后，对 6572 名生殖职业的自然分娩后重复早产的可能性进行了研究。该分析不仅针对怀孕数量进行控制，还针对生殖结果的性质进行控制。在大多数生殖序列中，一次妊娠与后续妊娠之间的相关性很弱。之前有或没有流产过的一次早产后，早产的风险增加了三倍，而在之前两次早产后，早产的风险增加了六倍。然而，归因风险较低，大多数早产经产者没有既往病史。
The likelihood of repetition of preterm birth after spontaneous onset of labour has been studied in 6572 reproductive careers after excluding stillbirths, multiple births, all careers in which any labour had been induced, and all careers in which the gestation length in any pregnancy was not certain. The analysis was controlled not only for pregnancy number, but for the nature of the reproductive outcomes. In most reproductive sequences there was a weak correlation between the gestation in one pregnancy and subsequent ones. The risk of preterm birth was tripled after one previous preterm birth with or without a preceding abortion, and increased six-fold after two previous preterm births. However, the attributable risk was low, and most multiparae with preterm births did not have a previous history.
