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.

RESUMEN Objetivos: evaluar la tendencia de las cesáreas, en el período de 2014 a 2020, en los sectores público y privado según la Clasificación de Robson. Métodos: estudio de serie temporal de la proporción de mujeres que tuvieron cesáreas entre 2014 y 2020, considerando la clasificación de Robson y el tipo de servicio. Para el análisis de tendencia, se utilizó la regresión de Prais-Winsten. Resultados: se observaron mayores proporciones de cesáreas en todos los grupos de Robson en el sector privado en comparación con el público, incluso con una tendencia a la reducción en el privado y un aumento en el público. También se registraron proporciones elevadas de cesáreas en grupos favorables al parto normal (Robson 1, 4 y 5). Conclusiones: a pesar de la tendencia a la reducción de las cesáreas en el sector privado, hubo una tendencia creciente en el público y una elevada proporción de cesáreas en mujeres con condiciones favorables al parto normal. Se destaca la necesidad de monitorear estos indicadores para evaluar y proponer intervenciones para la reducción de cesáreas innecesarias.

RESUMO Objetivos: avaliar a tendência de cesáreas, no período de 2014 a 2020, nos setores público e privado segundo a Classificação de Robson. Métodos: estudo de série temporal da proporção de mulheres que tiveram cesáreas entre 2014 e 2020, considerando a classificação de Robson e o tipo de serviço. Para análise de tendência, utilizou-se a regressão de Prais-Winsten. Resultados: observaram-se maiores proporções de cesáreas em todos os grupos de Robson no setor privado em relação ao público, mesmo com tendência de redução no privado e aumento no público. Também foram registradas elevadas proporções de cesáreas em grupos favoráveis ao parto normal (Robson 1, 4 e 5). Conclusões: apesar da tendência de redução das cesáreas no setor privado, houve tendência crescente no público e elevada proporção de cesáreas em mulheres com condições favoráveis ao parto normal. Ressalta-se a necessidade de monitorar esses indicadores para avaliar e propor intervenções para a redução de cesáreas desnecessárias.
