Description

Gestational diabetes mellitus impacts between 3-10% of pregnancies, and increases the risk of pregnancy complications and lifelong health effects for mother and child (Bellamy, Casas, Hingorani, & Williams, 2009; Ross, 2006; Ryser Rüetschi et al., 2016). About half of cases occur without an evident risk factor (American College of Obstetricians and Gynecologists (ACOG), 1994; Dode & Santos, 2009). The present study was designed to examine possible psychophysiological connections linking psychological stress and stress reactivity, the magnitude of an individual’s response to stress, to blood sugar metabolization during mid-pregnancy between 24-28 weeks gestation. Participants were recruited from Sanford Health in Fargo, where patients underwent routine Oral Glucose Tolerance Testing (OGTT) a diagnostic assessment in which higher results indicate less blood sugar metabolization. They also completed a Virtual Trier Social Stress Task while psychological and physiological markers of stress reactivity were assessed. Additionally, maternal stress and stress reactivity were assessed using psychosocial questionnaires. There was support for proposed psychophysiological connections, including models in which positive associations between OGTT and maternal stress and anxiety were moderated by psychological stress reactivity. Results suggest that both the presence of stress and a women’s responses to that stress are influential over blood glucose metabolization during pregnancy. Continuing research in this area may have implications for improving outcomes of women at higher risk of GDM and other adverse pregnancy and perinatal outcomes.
