It has been suggested that women who have had a pregnancy interval of 10 or more years would have prolonged labor in pregnancies after the first, as do primigravidas. In a series of 94 multiparas with 10 or more years between pregnancies and 63 age-matched, multiparous controls, there was no significant difference in the length of the latent phase of labor or of the first, second and third stages of active labor in the two groups. The concept of a "physiologic primigravida" in these cases should be abandoned.
有人提出，妊娠间隔达10年或更长时间的女性在首次妊娠后的后续妊娠中会出现产程延长的情况，初产妇也是如此。在一组94例妊娠间隔达10年或更长时间的经产妇和63例年龄匹配的经产妇对照组中，两组在潜伏期以及活跃期第一、第二和第三产程的时长方面均无显著差异。这些情况下“生理性初产妇”的概念应予以摒弃。
