- Risk factors for labor dystocia resulting in cesarean delivery (CD) are defined.
Why this matters
- Worldwide efforts are ongoing to understand and reduce high CD rate.
- Preconception counseling, as opposed to increased scrutiny of physicians during labor, may help reduce CD rates.
- Independent risk factors for CD:
- Higher BMI: 24.1 vs 22.6 kg/m2, P<.001>
- Advanced maternal age: 28.9 vs 27.3 years, P<.001>
- Longer gestational age: 285 vs 281 days, P<.001>
- Less advanced cervical status at admission: 1.5 vs 2.6 cm, P<.001>
- Chorioamnionitis: 95 vs 10, P<.001 and>
- Fetal malposition: 148 vs 7, P<.001.>
- 41.9% with severe obesity,
- 27.6% with overweight, and
- 13.6% with normal weight; P=.046.
- Retrospective, parity-matched, case-control study.
- Cohort obtained from medical records of a tertiary delivery unit between 2009 and 2012.
- Primiparous women who had a term CD as a result of dystocia (n=296) were compared with control participants (n=302).
- Maternal and neonatal characteristics were compared.
- Funding: Orion Research Foundation; Government of Finland.
- Study could not control for indication for CD.
