“…The 'Activity' component was included as a predictor of minimum FGM levels, with more active individuals exhibiting higher levels of FGM. This positive correlation between general activity and FGM levels may be reflecting the normal homeostatic function of glucorticoids, as a catabolic for glucose for daily activities (Sousa et al, 2015).…”

In this study, we tested the hypothesis that individual differences in behavioural profiles correlate to differences in stress-related behaviours and hormonal levels in captive brown capuchin monkeys (Sapajus libidinosus). Based on a sample of 25 animals, 143 h of behavioural data collection and 518 faecal samples, principal component analyses indicated the existence of four components that characterize the individuals´Genus Normative Behaviour (GNB) (KMO = 0.531, X 2 = 127.672, p < 0.001): 'Feeding', 'Sociability', 'Exploration', and 'Activity'. Other four components are related to stress coping styles (based on Behaviour Potentially Indicative of Stress -BPIS) (KMO = 0.550, X 2 = 329.303, p < 0.001): 'Self-directed'; 'Restless', 'Ingestion/Self-Scratching', and 'Stereotyped'. More active individuals exhibit rapid stress-related behaviours (r = 0.443; p = 0.044) while less active individuals exhibit more stationary stress-related behaviours (r = -0.519; p = 0.013). Akaike information criteria indicated that the best linear regression model to predict the physiological profile (Faecal Glucocorticoid Metabolites -FGM) included three GNB and three BPIS components. 'Sociability' (p < 0.05), 'Exploration' (p < 0.05), and 'Ingestion/Self-scratching' (p < 0.05) predicted lower FGM levels. 'Activity' (p < 0.05), 'Self-directed' (p < 0.05), and 'Stereotyped' (p < 0.05) predicted higher FGM levels. 'Feeding' and 'Restless' factors were not included in the models. Our results support previous studies indicating that animals within the same population differ in the way they behave and react to stressful conditions, and these are correlated to different physiological profiles. Mapping inter-individual differences in stress coping strategies may help clarify the long-term reported incongruity between behavioural and physiological indicators of welfare in captive animals, supporting better management practices and assisting translational models of the development of psychopathologies.

“…The modulation of physiological responses to stress is performed, in addition to the Autonomic Nervous System, by the Hypothalamic-Pituitary-Adrenal axis, which plays a fundamental role in the response to the external and internal stimuli of the stress agents, by regulating the circulating level of glucocorticoids 7 . Cortisol is one of these glucocorticoids secreted in response to stress and found in body fluids.…”

Objective: to analyze the relationship between psychosocial stress dimensions and salivary cortisol in military police officers. Method: cross-sectional and analytical study with 134 military police officers. The Effort-Reward Imbalance (ERI) Model scale has been used to assess psychosocial stress. Salivary cortisol was collected in three samples. The following tests were used: Student's t-test, Mann-Whitney, ANOVA, Bonferroni, Kruskal-Wallis and Dunn. Pearson and Spearman correlation methods were used, as well as multiple linear regression. Cortisol at night showed an ascending statistical association with the psychosocial reward (p=0.004) and a descending association with the effort-impairment scores (p=0.017). Being part of the Special Tactical Operations Group (GATE) and the diastolic blood pressure explained 13.5% of the variation in cortisol levels on waking up. The sectors GATE, Special Patrol of the Elite Squad of the Military Police and Motorcyclists explained 21.9% of the variation in cortisol levels 30-minute after awakening. The variables GATE sector and Effort Dimension explained 27.7% of the variation in cortisol levels at night. Conclusion: it was evidenced that salivary cortisol variation was influenced by individual, labor and psychosocial variables.
