In this cohort, serum 25-hydroxyvitamin D < 50 nmol/L in both early gestation and cord blood in boys and current serum 25-hydroxyvitamin D < 50 nmol/L in girls were independent risk factors for two to four points lower full-scale intelligence quotient at the age of 7 years. Vulnerability to hypovitaminosis D, especially in pregnancy, may relate to child sex.
