Objective:
Evaluate patient characteristics that are predictors of treatment response and outcomes in gestational diabetes STUDY DESIGN: Retrospective cohort of 265 women with gestational diabetes treated with diet/metformin and/or insulin in a single centre over 2 years.
Results:
Multinomial logistic regression showed that (after adjusting for age and ethnicity) women who were of normal weight were more likely to be on diet and women who were obese were more likely to be on metformin or metformin and insulin(p=0.014). Women who were obese were twice more likely to have labour induced than those with normal weight. Onset of labour was the only parameter significantly associated with a treatment modality among the three groups (p<0.001). There was no difference in the incidence of large for gestational age, neonatal admission, shoulder dystocia or still birth between the three groups.
Conclusions:
Maternal BMI appears to be the only parameter that is predictive of need for treatment with metformin/insulin and the modality of treatment does not have an effect on maternal and neonatal outcomes.
