[Changing trends and indications for cesarean section in the last few decades].

Cesarean section rates are increasing worldwide, which has been paralelled by an increase in primary cesarean delivery and decrease in vaginal birth after cesarean section. Behind the different frequencies there is a number of interrelated factors including advanced maternal age, increasing incidence of obesity, assisted reproductive technologies, and maternal request for non-medical reasons. The sub-optimal management of labor and the concerns about medical liability claims and litigations increase the number of abdominal deliveries. The author reviews the changing indications for cesarean deliveries in the last few decades and summarizes the effects on the obstetrical clinical practice.
