  • Abstract Objective: To establish whether failure to progress during labor poses a risk factor for another non-progressive labor (NPL) during the subsequent delivery. Methods: A retrospective cohort study including singleton pregnancies that failed to progress during the previous labor and resulted in a CS was conducted. Parturients were classified into three groups for both previous and subsequent labors: CS due to NPL stage I, stage II and an elective CS as a comparison group. Results: Out of 202,462 deliveries, 10,654 women met the inclusion criteria: 3,068 women were operated due to NPL stage I and 1218 due to NPL stage II; The comparison group included 6368 women. Using a multivariable logistic regression models, NPL stage I during the previous delivery was found as an independent risk factor for another NPL stage I in the subsequent labor (adjusted OR=2.9; 95% CI=2.4-3.7; p<0.001). Similarly, NPL at stage I or II was found to be an independent risk factor for a NPL stage II during the subsequent labor (adjusted OR=1.4; 95% CI=1.1-2.1; p=0.033; adjusted OR=5.3; 95% CI=3.7-7.5; p<0.001; respectively). Conclusion: A previous CS due to a NPL is an independent risk factor for another NPL in the subsequent pregnancy and for recurrent cesarean delivery.
