Objective: To evaluate the level of maternal physical activity effect on the perinatal outcomes of women with preterm premature rupture of membranes (PPROM)

Study Design: This is a pilot, prospective, observational multicenter cohort study. We approached patients admitted between 23 0/7 weeks to 32 0/7 weeks gestation with confirmed PPROM between January of 2014 and June of 2017 All patients received corticosteroids and latency antibiotics. Enrollment was done on third day of admission. Delivery occurred at 34 weeks per protocol via induction of labor or cesarean section as obstetrically indicated; or sooner if chorioamnionitis was diagnosed or spontaneous preterm labor occurred. Patients were provided a pedometer to wear for the duration of their antepartum course and they have maternal activity at lib and were encouraged to go to the physical therapy gymnasium.

Results: We enrolled 32 women. We stratified them in two groups: low activity as less than 500 step a day and higher maternal activity more than 500 steps a day, There were no significant differences in the demographics. Latency from PPROM to delivery were significantly prolonged in women with maternal activity > 500 steps a day: 11.0 ± 8.42 vs 21.18 ± 4.26 days p = 0.004. No maternal or fetal adverse outcomes were identified.

Conclusion: Maternal activity more than 500 steps a day showed a significant association with prolongation of latency
