3. Résumé

Results show that women «with GDM are at an increased risk of depression particularly during pregnancy underscoring the need to screen for depression in these mothers and provide supportive interventions. This study also emphasizes that prior psychiatric illness, and having a partner with a history of psychiatric illness impacts the risk of depression in both mothers and fathers highlighting the importance for healthcare providers to consider the mental health status of both parents.» (p. 1836) More specifically, from «the time of GDM screening to delivery, mothers with GDM had a nearly twofold higher risk of depression compared to mothers without GDM. Whereas GDM was not conclusively associated with depression during the 1-year postpartum period, later in life, there was a slightly higher risk of depression in women with a history of GDM compared to those without GDM. In contrast, no association between partner GDM status and paternal depression was observed.» (p. 1833)
