Among 3225 deliveries in two Cotonou public maternity units, 244 prima
ry cesarean section were observed during July 1988 to December 1989. P
rimary cesarean section incidence varied according to indications, mat
ernal parity and maternity care units. Foetal distress (65.9 %), malpr
esentation and cephalopelvic disproportion (22.1 %) were the dominant
organic risk factors for the primary cesarean section. Multivariate st
epwise logistic regression technique indicated that the most important
indications for the practice in Cotonou were mainly organic risk fact
ors, maternal height and parity as well as repeating stillborn history
. Practician experiences (OR = 6.6) and foetal distress (OR = 9.3) in
the decision making process were highly associated to cesarean section
and differed between maternity units. Authors provided some suggestio
n for improving the practice of cesarean section in Cotonou and in Ben
in.
