Key clinical point: Pregnant women with type 2 diabetes or prediabetes had significantly less gestational weight gain if they took metformin at any point in their pregnancies.
Major finding: Investigators found a greater likelihood of appropriate weight gain in the metformin group (69%; aOR 1.85; P = .002).
Study details: Retrospective cohort review of 284 women without metformin exposure and 227 with metformin exposure in pregnancy.
Disclosures: Dr. Adams reported no outside sources of funding and no conflicts of interest.
