Objective To evaluate pregnancy‐associated plasma protein A (PAPP‐A) and free β‐human chorionic gonadotrophin (β‐hCG) in relation to admission to a neonatal intensive care unit (NICU) and neonatal disease. Methods A total of 9450 singleton pregnant women who attended the prenatal screening program at Aarhus University Hospital between January 2005 and December 2007 were included. PAPP‐A and free β‐hCG were measured between gestational weeks 8 and 13 and converted into multiples of the median (MoM) values. Information about neonatal outcome was obtained from specific registration forms completed by senior neonatologists at the time of admission to and discharge from the NICU. Results Both PAPP‐A and free β‐hCG < 0.4 MoM were associated with admission to NICU (odds ratio 1.6; 95% confidence interval, 1.2–2.0 and odds ratio 1.5; 95% confidence interval, 1.1–2.1). The results could not be explained by preterm delivery or low birth weight, because adjusting for these factors did not affect the results. Low PAPP‐A was also significantly associated with neonatal hypoglycemia, jaundice, and low Apgar score and low free β‐hCG with jaundice. Conclusion Low PAPP‐A and free β‐hCG were significantly associated with admission to NICU and neonatal disease, independently from what could be expected because of preterm delivery or low birth weight.
