Cortisol awakening response and psychosocial factors: A systematic review and meta-analysis
Abstract
The magnitude of the cortisol awakening response, a relatively new indicator of hypothalamic-pituitary-adrenocortical (HPA) axis activation, has been related to a number of psychosocial factors. But findings have been inconsistent across studies. We systematically reviewed previous studies investigating the association between the cortisol awakening response and psychosocial factors. 147 eligible studies from 62 articles were identified. Separate analyses were carried out on the increase in cortisol following waking (CARi), and the integrated volume of cortisol released over the waking period (CARauc). We found that the CARi was positively associated with job stress and general life stress. It was negatively associated with fatigue, burnout, or exhaustion. There were less reliable negative associations between the CARi and positive affects. The CARauc was positively related to general life stress and negatively related to posttraumatic stress syndrome. This review concludes that different psychosocial factors are associated with an enhanced or reduced cortisol awakening response.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
