• Description:
  Objective: To investigate associations between shiftwork and diurnal salivary cortisol among 319 police officers (77.7% men). Methods: Information on shiftwork was obtained from the City of Buffalo, New York electronic payroll records. Saliva was collected using Salivettes at seven time points and analyzed for free cortisol concentrations (nmol/L) using a chemiluminescence immunoassay. Mean slopes and areas under the curve were compared across shift schedule using analysis of variance (ANOVA)/analysis of covariance (ANCOVA). Results: Officers working primarily on the night shift had a significantly shallower slope. Mean slope (nmol/L/minutes) of the cortisol curve varied significantly across shifts (day: -0.00332 +/- 0.00017, afternoon: -0.00313 +/- 0.00018, night: -0.00257 +/- 0.0002); adjusted P = 0.023. Conclusions: Our results suggest that night shiftwork is a workplace factor that may alter the response of the hypothalamic-pituitary-adrenal (HPA) axis to the circadian cues responsible for the pattern of the diurnal cortisol curve.
