In women with gestational diabetes mellitus, fibroblast growth factor 21 showed predictive performance for postpartum insulin resistance, as assessed using the homeostasis model assessment of insulin resistance. Receiver operating characteristic analysis showed the highest area under the curve for predicting postpartum insulin resistance at T1 (area under the curve, 0.871; bootstrap 95% confidence interval, 0.732\u20130.973). Fibroblast growth factor 21 concentrations appeared to decline during the early postpartum period, as indicated by significantly lower T3\/T1 ratios in samples from postpartum Days 5\u20137 compared with those from Days 1\u20134.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that perinatal fibroblast growth factor 21 dynamics may reflect physiological changes in insulin sensitivity and that fibroblast growth factor 21 concentrations measured during pregnancy may serve as a complementary indicator for postpartum metabolic risk stratification in women with gestational diabetes mellitus.
