Women with glucose intolerance postpartum had a similar insulin sensitivity [Matsuda index 0.656 (0.386 - 1.224) vs 0.778 (0.532 - 1.067), p = 0.709; 1/HOMA-IR 0.004 (0.002 - 0.009) vs (0.004 - 0.003 - 0.007), p = 0.384] but a lower beta-cell function compared to women with a normal OGTT postpartum, remaining significant after adjustment for confounders [ISSI-2 1.6 (1.2 - 2.1) vs 1.9 (1.7 - 2.4), p = 0.002].
