Abstract

Objective To compare first-stage labor patterns in women in preterm labor to those in labor at term. Study Design We performed a retrospective cohort study of consecutive women admitted from 2004 to 2008 with viable (≥24 weeks) vertex singleton gestations who reached the second stage of labor. Labor curves for preterm and term labor were created using a repeated-measures analysis with polynomial modeling. Interval-censored regression was used to estimate and compare median time of progression of labor. Multivariable analyses were performed to adjust for smoking, obesity (body mass index ≥30), induction, and nulliparity. The adjusted model was stratified by parity and induction of labor. Results Of 5,612 consecutive births, 224 were preterm (
