Correlation of first-trimester serum levels of pregnancy-associated plasma protein A with small-for-gestational-age neonates and preterm births.

Objective: To analyze the relationship between first-trimester levels of pregnancy-associated plasma protein A (PAPP-A) and small-for-gestational-age (SGA) neonates and preterm births, and to assess predictive utility for these events.

Methods: A prospective study was conducted among women undergoing first-trimester screening between January 1, 2012, and December 31, 2013, at two centers in Pune, India. Serum PAPP-A levels, pregnancy course, and outcome were assessed.
