Analysing the characteristics and outcomes of pregnant women with gestational diabetes according to insulin sensitivity, Benhalima et al.16 observed that patients with gestational and insulin-resistant diabetes presented higher rates of preterm births (8.5% vs. 4.7%, p = 0.030), need for induction of labour (42.7% vs. 28.1%, p < 0.001), total caesarean sections (28.7% vs. 19.4%, p = 0.00) and emergency caesarean sections (16.0% vs. 9.7%, p = 0.010) compared with women without diabetes. Here, INS is linked to insulin-resistant diabetes mellitus.
