Gestational diabetes & diabetes in pregnancy

Gestational diabetes and maternal morbidity in multifetal pregnancies: independent contributions of gestational diabetes mellitus (GDM) and plurality

Diabetes Res Clin PractPublished Retrospective cohort study

Authors' conclusion

Both GDM and multifetal gestation were independently associated with maternal morbidity. Multifetal gestation showed stronger associations with hypertensive outcomes, without evidence of interaction between the two exposures.

Participants
134,517 pregnancies
Exposure
GDM and multifetal gestation, alone and combined, vs singleton pregnancy without GDM
Outcome
Hypertensive disorders of pregnancy (HDP)
