The rising incidence and impact of non-medically indicated pre-labour cesarean section in Latin America.

In the poorest populations of the world the difficulties of performing a surgical procedure lead to extremely low cesarean section rates associated with very high perinatal mortality. Meanwhile the proportion of births by cesarean section has been increasing for several decades in many areas of the world, reaching alarmingly high rates especially in Latin America. This review aims to describe this secular trend. The causes of the increase in cesarean deliveries are analyzed with a multidimensional approach, trying to recognize the reasons behind the choice of the route of delivery. We are facing a shift in the guiding paradigm, leaving the classical biomedical one. Advantages and disadvantages of non-medically indicated cesarean section are being sought, comparing it with the results of vaginal delivery, with special emphasis on the short- and long-term morbidity of the newborn. Several variables involved in this controversial topic are considered, with the objective of stimulating critical thoughts about the medical, bioethical and social aspects of the increasing trend in the cesarean section rate.
