Effects of gender and age on the levels and circadian rhythmicity of plasma cortisol

Van Cauter, E.·1996·Journal of Clinical Endocrinology & Metabolism

Abstract

Data from rodent studies indicate that cumulative stress exposure may accelerate senescence and offer a theory to explain differences in the rate of aging. Cumulative exposure to glucocorticoids causes hippocampal defects, resulting in an impairment of the ability to terminate glucocorticoid secretion at the end of stress and, therefore, in increased exposure to glucocorticoids which, in turn, further decreases the ability of the hypothalamo-pituitary-adrenal axis to recover from a challenge. However, the consensus emerging from reviews of human studies is that basal corticotropic function is unaffected by aging, suggesting that the negative interaction of stress and aging does not occur in man. In the present study, a total of 177 temporal profiles of plasma cortisol from 90 normal men and 87 women, aged 18-83 yr, were collected from 7 laboratories and reanalyzed. Twelve parameters quantifying mean levels, value and timing of morning maximum and nocturnal nadir, circadian rhythm amplitude, and start and end of quiescent period were calculated for each individual profile. In both men and women, mean cortisol levels increased by 20-50% between 20-80 yr of age. Premenopausal women had slightly lower mean levels than men in the same age range, primarily because of lower morning maxima. The level of the nocturnal nadir increased progressively with aging in both sexes. An age-related elevation in the morning acrophase occurred in women, but not in men. The diurnal rhythmicity of cortisol secretion was preserved in old age, but the relative amplitude was dampened, and the timing of the circadian elevation was advanced. We conclude that there are marked gender-specific effects of aging on the levels and diurnal variation of human adrenocorticotropic activity, consistent with the hypothesis of the "wear and tear" of lifelong exposure to stress. The alterations in circadian amplitude and phase could be involved in the etiology of sleep disorders in the elderly.

  • Only two studies of 143 and 177 healthy men and women aged 20 to 80 years have documented high fidelity sampling of circulating cortisol patterns across an entire 24-h day.

    “Only two such studies, of 143 and 177 healthy men and women aged 20 to 80 years, respectively, are available [65, 66].”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [66]

    The Abstract (page not given) reports 177 cortisol profiles from normal men and women aged 18–83, supporting the study’s identification and approximate age range. The Subjects section (page not given) specifies that only 163 had 24-hour profiles; the other 14 were sampled for 8–10 hours overnight. Thus, the cited paper does not support the claim that all 177 had sampling across an entire 24-hour day. (LLM, conf=0.90)

  • Premenopausal women, but not older women, had lower 24-h and morning cortisol concentrations compared with age-matched men.

    “Premenopausal women, but not older women, had lower 24-h, and morning, cortisol concentrations compared with age-matched men [65, 66].”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [66]

  • 24-h cortisol concentrations were independent of age in one study, but increased with age in the other.

    “In contrast to the consistent findings previously outlined, 24-h cortisol concentrations were independent of age in one study [65], but increased with age in the other [66], for reasons that are not entirely apparent.”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [66]

  • Men above 30 years old were excluded to control for the impact of age on circadian rhythmicity of plasma cortisol.

    “Men above 30 years old were excluded to control for the impact of age on circadian rhythmicity of plasma cortisol (Van Cauter et al., 1996).”
  • Age is associated with higher late-afternoon and early-evening cortisol, and an advance in the timing of the cortisol rhythm, but not with cortisol-binding protein.

    “These [65, 66] and other [67] studies are consistent in showing that age is associated with higher late-afternoon and early-evening cortisol, and an advance in the timing (i.e. phase) of the cortisol rhythm, but not with cortisol-binding protein [68].”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [66]

    The citation [68] is attached specifically to the claim that age is not associated with cortisol-binding protein. The Results and Discussion passages address age-related cortisol levels and rhythm timing, but no passage found addresses cortisol-binding protein or corticosteroid-binding globulin (searched both terms).

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.
