Risk Factors and Pregnancy Outcomes of Twin Pregnancies With Gestational Diabetes Mellitus: A Comparison Based on Chorionicity.

ABSTRACT:

Background

There is insufficient evidence to determine whether the risk factors and pregnancy outcomes associated with gestational diabetes mellitus (GDM) in twin pregnancies vary by chorionicity.

Materials

A retrospective cohort study was conducted among twin pregnancies. GDM was diagnosed using the IADPSG diagnostic criteria. Logistic regression and generalized estimation equation (GEE) models were used to identify the risk factors of GDM and its impact on pregnancy outcomes, stratified by monochorionic (MC) and dichorionic (DC) pregnancies.

Results

Advanced maternal age (MC: aOR 2.18, 95% CI 1.25-3.81 and DC: aOR 1.32, 95% CI 1.06-1.67) and preexisting hypertension (MC: aOR 2.69, 95% CI 1.04-9.36 and DC: aOR 1.70, 95% CI 1.12-2.59) were risk factors for GDM regardl
