RESUMEN
Adverse childhood experiences (ACE) enhance the risk for mental disorders, e.g. major depressive disorder (MDD). Increasing evidence suggests an association between ACE and impaired physical health, e.g. metabolic syndrome. The aim of this study was to assess several metabolic risk markers in healthy individuals with and without ACE and depressed patients with and without ACE. We examined glucose and insulin release in the oGTT in 33 women with MDD and ACE, 47 women with MDD without ACE, 21 women with ACE but no current or lifetime MDD and 36 healthy women without either MDD or ACE. Several metabolic markers such as triglycerides, cholesterol, LDL, HDL, HbA1c, BMI and waist to hip ratio were assessed. The four groups did neither differ in insulin release and glucose concentrations in the oGTT nor with respect to other metabolic variables. Depressed patients with and without psychotropic medication did not differ in any outcome variable, but there was a trend towards higher glucose concentrations in the oGTT in patients with current psychotropic medication. In this physically healthy sample neither ACE nor MDD were associated with metabolic risk factors. Thus, metabolic alterations might not directly be linked to ACE and depression.

BACKGROUND: Adverse childhood experiences (ACE) increase the risk to develop major depressive disorder (MDD) and obesity or metabolic syndrome in adulthood. In addition, ACE may be associated with an exaggerated endocrine response to stress, which, in turn, may lead to enhanced food intake resulting in obesity and metabolic problems. METHODS: We systematically examined the stress response and consecutive food intake in 32 women with MDD and ACE as determined by a clinical interview (Early Trauma Inventory), 52 women with MDD without ACE, 22 women with ACE but no current or lifetime MDD and 37 healthy women without either MDD or ACE. All participants underwent a psychosocial stress test (Trier Social Stress Test, TSST) and a control condition (Placebo-TSST) before they were offered a buffet of snacks. Participants were not aware that the primary outcome variable was the amount of consumed kilocalories (kcal). RESULTS: The four groups did not differ in demographic variables. Stress resulted in higher cortisol release and higher blood pressure compared to the control condition. Patients with MDD without ACE had a significantly lower cortisol response to stress compared to controls. Across groups, we found higher kcal intake after stress compared to the control condition. Comparing high and low cortisol responders to stress, higher kcal intake after stress was only seen in those with low cortisol release. CONCLUSIONS: This study provides evidence that blunted rather than enhanced cortisol release to stress might lead to increased food intake, independent from MDD and ACE.
