The purpose of this study was to determine whether planned cesarean delivery for the singleton fetus in breech presen-tation at term reduces the risk of dea th or neurodevelop-mental delay at 2years of age.In sele cted centers in the Term Breech Trial,children were screened for abnormali-ties at≥2years of age with the Ages and Stages Ques-tionnaire,followed by a neurodevelopmental assessment if the Ages and Stages Questionnaire sc ore was abnormal.A total of 923of 1159children(79.6%)from 85centers were followed to 2years of age.The risk of death or neu-rodevelopmental delay was no different for the planned ce-sarean than for the planned vaginal birth groups(14chil-dren3.1%vs 13children2.8%;relative risk,1.09;95%CI,0.52-2.30;P =.85;risk diffe rence,+0.3%;95%CI,-1.9%,+2.4%).Planned cesarean delivery is not associated with a red uction in risk of death or neurodevelopmental delay in childr en at 2years of age.
