GLP-1 receptor agonist exposure in the periconceptional period and adverse obstetric outcomes: A systematic review and meta-analysis

This systematic review and meta-analysis assesses whether exposure to glucagon-like peptide-1 receptor agonists (GLP-1 RAs) during pregnancy or the periconceptional period is associated with adverse maternal and perinatal outcomes.

Medline, Embase, and the Cochrane Library were searched for observational studies comparing pregnancies exposed and unexposed to GLP-1 RAs within 6 months before a positive pregnancy test. Outcomes included miscarriage, intrauterine death, congenital anomalies, preterm birth (PTB), hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus (GDM), fetal growth restriction (FGR), small for gestational age (SGA), large for gestational age (LGA), and excess gestational weight gain. Random-effects meta-analyses and subgroup analyses by indication were performed.
