RESUMEN
Objective: To explore the relationship between prenatal anxiety and cesarean section (c-section) with non-medical indication. Methods: Nested case-control study was used to analyze the risk factors for c-section with no medical needs: 433 pregnant women with gestational age longer than 24 weeks were enroled in this study. According to the mode of delivery, we divided them into a vaginal delivery group, a c-section group without medical need and a c-section group with medical need. Results: The c-section rate was 62.1%, 55.8% of which was c-section without medical need at family request. The score of state anxiety (S-AI) and trait anxiety (T-AI) was 42.53±11.04 and 44.40±10.23 respectively, much higher than that of normal population. After the adjustment of maternal social economic status and other prenatal statuses for this pregnancy, the prenatal anxiety was still associated with c-section with non-medical indication. The adjusted odd ratio for prenatal anxiety state, prenatal trait anxiety state and c-section with non-medical indication was 1.41 (95%CI: 1.06-1.87) and 1.23 (95% CI: 1.08-1.40), respectively. Conclusion: Prenatal anxiety state is a risk factor for c-section with non-medical indication.
