Trends in cesarean section rates in Brazil by Robson classification group, 2014-2020

Objectives: to evaluate the trends in cesarean sections from 2014 to 2020 across both public and private sectors, utilizing the Robson Classification. Methods: this time series study analyzed the proportion of women who underwent cesarean sections between 2014 and 2020, considering both the Robson classification and the type of healthcare service. Trend analysis was conducted using the Prais-Winsten regression. Results: higher proportions of cesarean sections were observed in all Robson groups within the private sector compared to the public sector. This was despite a decreasing trend in the private sector and an increasing trend in the public sector. Notably, elevated proportions of cesarean sections were recorded in groups that are typically favorable to normal childbirth (Robson 1, 4, and 5). Conclusions: although there was a decreasing trend in cesarean sections within the private sector, an increasing trend was observed in the public sector. Additionally, there was a high proportion of cesarean sections among women with conditions favorable to normal childbirth. It is crucial to continuously monitor these indicators to evaluate and implement interventions aimed at reducing unnecessary cesarean sections.
