Abstract
In a sample of 300 adolescents, those with a history of major depression disorder (MDD) exhibited flatter diurnal cortisol slopes than peers without internalizing disorders.
- Adolescents with past MDD and recent MDD comorbid with anxiety disorders showed reduced cortisol variation throughout the day.
- Increased general distress was linked to flatter cortisol slopes, suggesting a potential relationship between emotional state and HPA axis functioning.
- Feelings of sadness and loneliness correlated with flatter cortisol slopes and contributed to the link between comorbid MDD and anxiety disorders.
- Past experiences of MDD may leave a lasting impact on cortisol slopes, independent of current negative emotions or life stress.
