Salivary Cortisol Levels and Stress Reactivity in Human Aging

Abstract

BACKGROUND: While homeostatic mechanisms are generally believed to become less efficient in the aging organism, evidence for changes in hypothalamic-pituitary-adrenal function is inconclusive. Previous studies report higher, lower, or unchanged basal cortisol levels in human aging. Delayed recovery of glucocorticoids to baseline following stress exposure has been observed in aging rats, but the generalizability of these findings to humans remains unclear. METHODS: Salivary-free cortisol was measured at home and in response to a laboratory speech task in 56 healthy men and women in three age groups (range 43-86 yr). RESULTS: Higher basal cortisol levels were observed in older age groups. Gender, recent life stress, and current distress showed no relationship to basal levels. The magnitude of cortisol responses to the speech task differed by age, with the smallest responses in the oldest group. This pattern was robust in men, with the youngest subjects (40-59 yr) showing both the largest and the most prolonged responses. While women > 70 yr were least likely to show any response, other analyses failed to show age effects on reactivity in women, perhaps because anticipatory baseline elevations limited subsequent cortisol response. CONCLUSIONS: Results indicate moderate increases in basal cortisol levels, but do not support the hypothesis that cortisol responses to a stressor increase in magnitude or duration during normal human aging. Gender differences in stress reactivity warrant further investigation.

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.
