Breech presentation in South Australia, 1987-1989

|February 1, 1993
Summary
Breech presentation in babies is linked to increased risks for mothers and newborns, including higher rates of neonatal morbidity and perinatal mortality. This finding suggests breech presentation may indicate underlying fetal or maternal health issues.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Fetal Development
Background:
- Breech presentation complicates a significant number of deliveries.
- Understanding the associated maternal and fetal risks is crucial for optimizing obstetric care.
Purpose of the Study:
- To compare maternal, obstetrical, labor, and pregnancy outcomes between breech and vertex presentations.
- To investigate the association between breech presentation and perinatal mortality, adjusting for confounding factors.
Main Methods:
- Retrospective comparison of 2,412 breech births with 17,946 vertex births.
- Statistical analysis, including unconditional multiple logistic regression, to assess risk factors and outcomes.
Main Results:
- Mothers of breech babies had higher rates of previous miscarriage, obstetric complications, threatened labor, and Cesarean sections.
- Breech presentations were associated with significantly higher neonatal morbidity and perinatal mortality (almost 9 times higher).
- Increased rates of intrauterine growth retardation, prematurity, low birth-weight, low Apgar scores, and congenital anomalies were observed in breech infants.
Conclusions:
- Breech presentation is a significant risk factor for adverse perinatal outcomes, even after adjusting for low birth-weight and congenital anomalies.
- The findings suggest breech presentation may serve as a marker for preconceptional or prenatal disturbances.
- An unexplained excess of breech presentations in females may indicate fetal genetic or hormonal susceptibility.
