研究目的：本研究的目的是确定黑人与白色妇女相比，第一产程的持续时间和进展是否不同。研究设计：对连续黑人（n= 3，924）和白色（n= 921）单胎足月妊娠（≥ 37周）妇女完成第一产程的产程进展进行回顾性队列研究。使用区间删失回归估计分娩持续时间和从1 cm到下一个的进展。整个队列中黑人和白色妇女的产程持续时间和进展，并按产次分层，采用多变量区间删失回归模型进行比较。重复测量分析与第九次多项式modeling被用来构建平均劳动curves.ResultsThere是没有显着差异的第一阶段的劳动力在黑色相比，白色妇女（中位数，4-10厘米：5.1与4.9小时[p= 0.43]为nullparous和3.5与3.9小时[p= 0.84]为多产妇女）。同样，以1 cm为增量的进展无显著差异。平均劳动力曲线也没有显着different.ConclusionDuration和进步的第一阶段的劳动力是相同的黑人和白色妇女。这表明类似的标准可能适用于第一阶段的劳动。
ObjectiveThe objective of this study was to determine whether the duration and progress of the first stage of labor are different in black compared with white women.Study DesignRetrospective cohort study of labor progress among consecutive black (n= 3,924) and white (n= 921) women with singleton term pregnancies (≥ 37 weeks) who completed the first stage of labor. Duration of labor and progression from 1 cm to the next was estimated using interval-censored regression. Labor duration and progress among black and white women in the entire cohort, and stratified by parity, were compared in multivariable interval-censored regression models. Repeated-measures analysis with 9th-degree polynomial modeling was used to construct average labor curves.ResultsThere were no significant differences in duration of the first stage of labor in black compared with white women (median, 4–10 cm: 5.1 vs. 4.9 hours [p= 0.43] for nulliparous and 3.5 vs. 3.9 hours [p= 0.84] for multiparous women). Similarly, there were no significant differences in progression in increments of 1 cm. Average labor curves were also not significantly different.ConclusionDuration and progress of the first stage of labor are identical in black and white women. This suggests similar standards may be applied in the first stage of labor.
