['To determine factors associated with latency time to birth after preterm premature rupture of membranes (PPROM) and the impact on neonatal outcomes.', 'Data on singleton pregnancies with PPROM (n=1535 infants) were prospectively collected in a computerized perinatal/neonatal database at a tertiary care perinatal center. Latency was characterized as ≤72h versus >72\u2009h after PPROM.', 'The percentage of women with latency to birth >72\u2009h decreased from 67% in very preterm (gestational age (GA) 25 to 28 weeks) to 10% in late preterm women (GA 33 to 36 weeks). PPROM women with latency ≤72\u2009h were more likely to have pregnancy-induced hypertension and birth weight <3%; PPROM women with latency >72\u2009h were more likely to have received steroids and develop clinical chorioamnionitis. PPROM <32 weeks GA with latency ≤72\u2009h was associated with a two-fold higher incidence of severe neonatal morbidity, while PPROM between 29 to 34 weeks GA and latency ≤72\u2009h was associated with a higher incidence of moderate neonatal morbidity.'] Are neonatal outcomes associated with latency after preterm premature rupture of membranes?
