OBJECTIVE: To investigate the association of D-dimer level during late pregnancy with birth outcomes in a Chinese population.
METHODS: A retrospective observational cohort study of 11,570 pregnant women who delivered in a single central hospital was conducted. Maternal plasma D-dimer levels at hospital admission and pregnancy outcomes were abstracted and analyzed from laboratory information system and hospital records, respectively.
RESULTS: Maternal plasma D-dimer levels were associated with higher fetal growth indicators for the highest vs. lowest quartile (Q) of D-dimer (mean birth weight: 145.79 g, mean birth length: 0.11 cm, mean gestational age: 0.30 week). Increase in D-dimer quartiles were associated with an decreased risk for small for gestational age (SGA), low birth weight (LBW) and preterm birth (PTB) neonates, and with an increased risk for large for gestational age (LGA), and macrosomia infants (SGA: OR = 0.52, 95% CI: 0.43, 0.64; LBW: OR = 0.58, 95% CI: 0.38, 0.86; PTB: OR = 0.44, 95% CI: 0.35, 0.55; LGA: OR = 2.37, 95% CI: 2.01, 2.78; macrosomia: OR = 2.59, 95% CI, 2.06, 3.24; for Q4 vs. Q1).
CONCLUSION: Maternal plasma D-dimer levels during late pregnancy were associated with birth outcomes and had risk evaluation value for these outcomes.
