title: [Sex specific differences in physiologic response to stress evaluated by means of salivary cortisol].
abstract: The psychophysiological mechanism behind the development of stress-related diseases includes a long-term both increase and decrease in circulating cortisol levels, leading to an allostatic disregulation of the hypothalamic-pituitary-adrenal (HPA) axis. This research explores the relationship between perceived stress (assessed by means of the Job Strain Model) and neuroendocrine response quantified by means of repeated measures of salivary cortisol in 46 call-centre operators. Job strain influenced the total amount of cortisol response to waking, but not the cortisol excretion in the remainder of the day. The cortisol response to waking showed gender-specific differences, women excreting greater cortisol than men [AUC(t): coeff (IC 95%) = 16.2 (5.3-27.1); AUC(i): coeff (IC 95%) = 8.3 (2.4-14.2); MnInc: coeff (IC 95%) = 5.2 (1.6-8.9)]. In long run the gender-specific differences of the dis-regulation of the hypothalamic -pituitary-adrenal (HPA) axis can be related to differences on prevalence of autoimmune diseases.
