Prevalence of cesarean section and associated factors in a municipality of the brazilian amazon
Abstract
Objective: To analyze the prevalence and factors associated with cesarean section in a municipality in the countryside of the Brazilian Western Amazon. Method: This is a cross-sectional and retrospective study, using secondary birth data from Cruzeiro do Sul, Acre, from 2018 to 2021, collected from the Live Birth Information System (SINASC). Poisson regression was used to calculate crude and adjusted prevalence ratios with their respective confidence intervals. Statistical analyses were performed using Stata software, version 17.0, adopting a significance level of p <0.05. Results: 11,770 births were analyzed, of which 49.96% occurred via cesarean section. The highest prevalence was recorded in 2020 (56.24%), followed by a reduction in 2021 (53.09%). Cesarean section was more common among mothers over 40 years of age, white, who worked outside the home, and who had undergone a previous cesarean section. Conversely, the lowest prevalence was observed among mothers who worked in agriculture, were single, or had few prenatal visits. Neonatal characteristics associated with cesarean section include low birth weight and Apgar scores at 1 and 5 minutes. Conclusion: The prevalence of cesarean sections exceeds international recommendations and was influenced by maternal and neonatal factors, as well as the pandemic context.
