Takeaway

  • Late abortion may have a small but significant risk for preterm birth and perinatal death in future pregnancy.

Why this matters

  • Contraception or abortion at an earlier gestational age may prevent some perinatal risks.
  • Increased antepartum surveillance with history of late abortion may be warranted.

Key results

  • Compared with women with abortion
  • After adjustment for variables, risk for extremely preterm birth was higher in women with abortion ≥12 weeks compared with women with abortion
  • OR, 2.28 (95% CI, 1.53-3.39).

Study design

  • Retrospective registry-based cohort study.
  • Cohort identified from the Finnish Medical Birth Register and the Abortion Register.
  • First-time mothers with singleton births between 1996 and 2013 were identified.
  • Those with prior abortion
  • Logistic regression analysis was used to estimate the risk for birth outcomes including preterm birth, low birth weight, and perinatal death.
  • Funding: The Finnish Cultural Foundation.

Limitations

  • Method of abortion not considered.
  • Studied outcomes are rare.
