INS and gestational diabetes: Multivariable logistic regression analysis showed that significant predictors of dysglycaemia were black (OR 2.09; 95% CI: 1.27–3.46) and mixed ethnicity (OR 3.05; 95% CI: 1.26–7.42), diagnosis of GDM before 24 weeks gestation (OR 3.05, 95% CI: 1.90–4.91), and treatment of GDM with metformin (OR 1.63; 95% CI: 1.05–2.55) or insulin (OR 2.08; 95% CI: 1.14–3.79) rather than diet alone.
