We describe characteristics and risk factors regarding pregnancy outcome in women with a preconception body mass index ( BMI ) >50 kg/m 2 compared with women with BMI ≤50 kg/m 2 in a retrospective population cohort study in singleton pregnancies from the Danish Medical Birth Registry. Results were analyzed as relative risks by a two‐proportion z ‐test. Women with preconception BMI >50 kg/m 2 smoked, developed gestational diabetes and pre‐eclampsia, and needed induction of labor more frequently than mothers with BMI ≤50 kg/m 2 . Examination of the case records showed that many attempted vaginal delivery without epidural analgesia, 21% needed an emergency cesarean section (compared with 12% among women with BMI ≤50 kg/m 2 ), and 25% underwent general anesthesia in this context. Many neonates were macrosomic and 34% needed neonatal intensive care and early feeding compared with 6% of neonates from women with BMI ≤50 kg/m 2 . Women with an extremely high preconception BMI develop more pregnancy complications and their neonates appear affected by this as well.
