The Association of Hair Cortisol with Self-Reported Chronic Psychosocial Stress and Symptoms of Anxiety and Depression in Women Shortly after Delivery.

HCC were not found to correlate with self-reports of chronic stress, anxiety, or depressive symptomatology. Among other things, these findings could reflect problems with questionnaire-based assessments obtained shortly after delivery such as recall bias and/or suggest that associations between cortisol secretion and psychosocial stress are difficult to detect due to, e.g. a strong physiological increase of cortisol in the last trimester.
