Occurrence of cesarean according to Robson's criteria in two brazilian cohorts

Objective: To analyze cesarean delivery according to Robson's criteria in the birth cohorts of São Luís – MA and Ribeirão Preto – SP. Methods: Cross-sectional study conducted with mothers and newborns participating in the BRISA Cohort. Descriptive analyzes were performed using the STATA/SE 14.0 program. Results: In São Luís, 47.52% of births were cesarean sections, and in Ribeirão Preto, 59.82%. When distributing puerperal women within the 10 groups of the Robson Classification, a greater relative contribution to the cesarean section rate is observed in group 4 (multiparous women, without previous cesarean section, with a single fetus, cephalic, ≥ 37 weeks, whose delivery is induced or who undergo a cesarean section before the onset of labor) and 5 (multiparous women with at least one previous cesarean section, with a single fetus, cephalic, ≥ 37 weeks). Conclusions: Groups 4 and 5 showed greater relative contributions to cesarean rates, requiring the implementation of strategies to reduce cesarean sections in these groups.
