Abstract

CONTEXT: The hypothalamic pituitary-adrenal axis is thought to play a role in Type 2 Diabetes (T2D). However, the evidence for an association between diurnal cortisol patterns and T2D is equivocal. OBJECTIVE: The aim was to examine the association of cortisol patterns throughout the day with T2D status in a community-dwelling population. DESIGN: This was a cross-sectional study of T2D status and salivary cortisol from phase 7 (2002-2004) of the Whitehall II study, United Kingdom. SETTING: The occupational cohort was originally recruited in 1985-1988. PARTICIPANTS: Three-thousand, five-hundred eight white men and women including 238 participants with T2D aged 50-74 years with complete information on cortisol secretion participated. OUTCOME MEASURES: We measured diurnal cortisol (nmol/L) patterns from six saliva samples obtained over the course of a normal day: at waking, +30 min, +2.5, +8, +12 hours, and bedtime. The cortisol awakening response and slope in diurnal secretion were calculated. RESULTS: T2D status was associated with a flatter slope in cortisol decline across the day (b = 0.004; confidence interval [CI], 0.001-0.007; P = .014) and greater bedtime cortisol (b = 0.063; CI, 0.010-0.117; P = 0.020) independent of a wide range of covariates measured at the time of cortisol assessment. There was no association between morning cortisol, the cortisol awakening response, and T2D (P > .05). CONCLUSIONS: In this nonclinical population, T2D was associated with a flatter slope in cortisol levels across the day and raised bedtime cortisol values.

  • In the largest study to date, over 3,500 individuals from the Whitehall II cohort with T2DM had a flatter slope in levels of cortisol across the day and raised evening concentrations of cortisol compared with healthy individuals.

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.
