Methods: A cross-sectional study was conducted using data from the 2019 National Health Survey (Pesquisa Nacional de Sa\u00fade \u2013 PNS). Data from 2,875 women were analyzed. Chi-square tests and logistic regression were used to investigate the association between sociodemographic characteristics, childbirth care indicators, and the occurrence of childbirth complications (outcome).  Results: The prevalence of childbirth complications was 12.3% (95%CI 10.6\u201314.2). Childbirth complications were more prevalent among women with lower educational attainment (14.4%) and lower income (13.9%), chronic hypertension (37.1%) or hypertension occurring only during pregnancy (29.8%), cesarean delivery (13.9%), and delivery through the Brazilian Unified Health System (Sistema \u00danico de Sa\u00fade \u2013 SUS) (14.5%), compared with their respective reference groups (p&lt;0.05). The multivariate logistic regression model showed significant associations between the outcome and chronic hypertension (OR=5.49; 95%CI 2.90\u201310.41), gestational hypertension (OR=4.18; 95%CI 2.47\u20137.08), absence of blood pressure measurement during prenatal visits (OR=2.16; 95%CI 1.01\u20134.67), delivery through SUS (OR=1.99; 95%CI 1.06\u20133.71), cesarean delivery without labor (OR=1.75; 95%CI 1.10\u20132.80), and medically indicated cesarean delivery (OR=1.90; 95%CI 1.06\u20133.41). Among women who experienced childbirth complications, the odds of neonatal problems were higher (OR=4.12; 95%CI 2.48\u20136.85), as were the odds of low birth weight (OR=2.59; 95%CI 1.58\u20134.23) and preterm birth (OR=2.43; 95%CI 1.60\u20133.68).  Conclusion: Clinical factors and characteristics of childbirth care were associated with the occurrence of childbirth complications in Brazil. Furthermore, women who experienced childbirth complications had higher odds of adverse neonatal outcomes.<\/jats:p>","DOI":"10.1590\/1980-549720260053","type":"journal-article","created":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T10:46:16Z","timestamp":1792406776000},"source":"Crossref","is-referenced-by-count":0,"title":["Childbirth
