Concurrence of gestational diabetes and pre-gravid obesity (''diabesity'') in twin gestations

Abstract Objective: To assess the effect of the concurrence of gestational diabetes mellitus (GDM) and pre-gravid obesity in twin gestations (''diabesity''). Methods: We compared perinatal outcomes of twin gestation in mothers with GDM and pregravid obesity (1.7%), mothers with GDM but with normal BMI (6.2%), and obese mothers without GDM (7.0%). Results: Twin pregnancies with ''diabesity'' were associated with significantly higher incidence of stillbirth (OR ¼ 6.4; 95%CI ¼ 1.4, 33.4) and existing chronic hypertension (OR ¼ 4.2; 95%CI ¼ 1.2, 14.8) than in GDM pregnancies without obesity, and with births at 33-36 weeks as compared with the other groups. Otherwise, the comparisons showed remarkable similar results in terms of gestational age, birth weight, preeclampsia, cesarean section rate, and fetalneonatal outcomes. Conclusion: It appears that diabesity has a relatively minor effect in twins. If this will be confirmed by other studies, it would be important to elucidate how twins ameliorate the adverse outcomes of diabesity
