A study conducted in Rio Grande do Sul, Southern Brazil, found that the prevalence of episiotomy decreased significantly over a five-year period, but it was more likely to occur in women at lower risk of birth complications.
OBJECTIVE: To identify and analyze the prevalence, trend, and factors associated with episiotomy in Rio Grande, in the state of Rio Grande do Sul, Southern Brazil. METHODS: A single, standardized questionnaire was applied to all pregnant women, residents in the municipality of Rio Grande, who had children in local hospitals between January 1 and December 12 of the years 2007, 2010, 2013, 2016 e 2019. Demographic and socioeconomic characteristics were investigated, as well as the assistance received during pregnancy and delivery. Chi-square test was used to compare proportions and Poisson regression with robust variance adjustment was used for multivariable analysis. Prevalence ratio (PR) was used as effect measure. RESULTS: Among the 12,645 births that occurred in the five years, 5,714 (45.2%) were vaginal delivery. Of these mothers, 2,930 (51.3%; 95%CI: 50.0%-52.6%) underwent episiotomy. Over this period, the episiotomy rate decreased from 70.9% (68.4-73.5) in 2007 to 19.4% (17.1-21.7) in 2019. Adjusted analysis showed a high PR of episiotomy occurrence among women who were young (PR = 2.23; 95%CI: 1.89-2.63), had higher education (PR = 1.21; 95%CI: 1.03-1.42), had a higher family income (PR = 1.25; 95%CI: 1.10-1.41), were primiparous (PR = 3.41; 95%CI: 2.95-3.95), had prenatal care in the private sector (PR = 1.25; 95%CI: 1.07-1.46), had oxytocin-induced labor (PR = 1.18; 95%CI:1.09-1.27), underwent forceps (PR = 1.32; 95%CI: 1.16-1.50), and whose newborn weighed 4,000 g or more (PR = 1.43; 95%CI: 1.14-1.80). CONCLUSION: Although the prevalence of episiotomy fell sharply within the studied period, its occurrence is more likely among women at lower risk of birth complications.
