Abstract:
To evaluate the association between circadian health parameters and psychological and biological vulnerability, a cross-sectional study was conducted with 15 undergraduate medical interns using the Brief Resilience Scale, the Mini International Neuropsychiatric Interview, and an ambulatory circadian monitoring device. Circadian Health construct was confirmed by factor analysis. Vulnerability factors (history of depression and low resilience) were associated to lower circadian health of motor activity and temperature rhythms. The findings suggest that not only being depressed but also having had depressive episodes in the past, as well as having low resilience, are associated with chronodisruption, and may increase the risk for developing new episodes of depression.
