  1. aAdjusted for maternal age, parity, maternal pre-pregnancy BMI, birth weight, smoking habits, need for interpreter, maternity unit, and birth year. We also controlled for pre-pregnancy risks which included: former IUGR, caesarean sections, and preterm births. And complications during pregnancy included: malformations; alcohol or drug abuse; IVF; primiparous < 20; preeclampsia; hypertension; diabetes; premature contractions < 37 weeks of gestation; vaginal bleeding < 37 weeks of gestation; placental abnormalities; uterine abnormalities, and blood type incompatibilities (Rh, ABO, platelets, hydrops foetalis, and other kinds of blood type incompatibilities)
