Ruohomäki A, et al. - Researchers investigated whether an association exists between gestational diabetes mellitus (GDM) and postpartum depressive symptomatology (PPDS). For this study, they analyzed 1066 women with no previous mental health issues enrolled in the Kuopio Birth Cohort (KuBiCo, www.kubico.fi). As per findings, gestational diabetes seems to be associated with an increased risk of postpartum depression. This association seems not mediated by third-trimester depression. They identified a significant association between GDM and PPDS in the subgroup of women with available data on first-trimester depression (n = 505).
