  "abstract": "Background and Aims Obesity is a important issue in pregnant women, who are more susceptible to complications that may affect both maternal and neonatal outcomes. Obese pregnant women more often require cesarean sections (CS), which carry additional potential anesthetic complications. The authors aim to assess the impact of obesity on anesthetic, obstetric, and neonatal outcomes in elective CS performed in 2024 at Centro Materno-Infantil do Norte (CMIN).Methods In 2024, a total of 735 cesarean deliveries were recorded at CMIN. After applying the exclusion criteria, the final sample included 249 pregnant women who underwent elective cesarean sections. These participants were categorized based on their preconception BMI into three groups: underweight/normal weight, overweight, and obese. Data on anesthetic management, as well as obstetric and neonatal outcomes, were collected and classified as either continuous or categorical variables. Continuous variables were analyzed using one-way ANOVA with Scheffé post hoc tests, while categorical variables were assessed using Pearson’s chi-square test. Statistical significance was defined as a bilateral p-value of < 0.05.Results The prevalence of obesity was 24.9%. Obese women had a higher number of pregnancies and deliveries (p = 0.001 and p < 0.001, respectively). Newborns of women with a BMI ≥ 30 kg/m 2 had significantly higher birth weight, length, and head circumference (p = 0.003 and p = 0.004, respectively). Statistically significant differences were also observed in the number of neuraxial anesthesia puncture attempts (p = 0.047), which increased with higher BMI categories, and in the use of vasopressors during cesarean sections (p = 0.030), which was more frequent among overweight women. The duration of surgery was also significantly longer in the obese group (p = 0.013).Conclusions The findings are consistent with the literature on the negative outcomes associated with obesity during pregnancy, highlighting its adverse impact on affected women and the importance of prevention/treatment strategies.",
