Mode of delivery and psychological development

The association between mode of delivery [specifically birth by Cesarean section (CS)] and induction of labor (IOL) psychological development at age 7 was assessed [including autism spectrum disorders (ASD), attention-deficit/hyperactivity disorder (ADHD) and behavioral difficulties]. The Millennium cohort study, a nationally representative UK cohort of children (including 13,141 children), was used. There was no association between planned CS and ASD [aOR 0.58; (95 % CI 0.19-1.79)] or ADHD [aOR 0.54; (95 % CI 0.18-1.64)] analyses. Induced vaginal delivery was more significantly associated with behavioral difficulties in unadjusted [OR 1.26; (95 % CI 1.03-1.54)] than in not adjusted analysis [OR 1.15; (95 % CI 0.82-1.60)].
