title: Breech delivery. An obstetrical analysis.
abstract: Fivehundred and eighty consecutive breech births during the period 1972-79 were analvsed for factors associated with neonatal mortality. The overall neonatal mortality in breech deliveries in this series of cases was 4.1%. Multivariate analyses (logistic regression) selected only 4 of 56 variables tested as significant (p less than 0.05) risk factors for neonatal death. The overall most important risk factor was low birth weight (p less than 0.0001). In addition, diabetes in the mother, malformations, and Apgar score 5 min less than 7 increased the risk of neonatal death. Cesarean section was carried out in 8.1% during the period 1972-75, but increased to 32.6% from 1976-79 without any reduction in neonatal mortality. Neonatal mortality figures were not significantly improved for infant delivered by cesarean section compared with those born vaginally.
