Abstract: In the last years, a number of studies have sought to demonstrate that adverse childhood experiences have a major impact on both childhood and adulthood. Adverse experiences being abandonment, mistreatment, violence against the vulnerable and unfavorable socioeconomic conditions, such as poverty, very low-income index, and region of urban violence. Studying childhood stress due to adverse childhood experiences is a big challenge. The majority of studies focus on three lines of investigation: cortisol analysis by various methods that include saliva, urine, hair, nails, sweat, cerebrospinal fluid, plasma and serum; stress analysis through the most varied stress scales for childhood and adolescence, and the association of cortisol with Tier Social Stress Test (TSST) scales, which consists of an experiment in which the participant exposes himself to speaking in public and then performs a mental task. Regardless of the method for assessing childhood stress, there is a point of convergence between the studies, which is the dysregulation of the HPA axis and the impacts on the SNS and the SNAM and cortisol production. The dysregulation of the hypothalamicpituitary-adrenal (HPA) axis is particularly a characteristic of several neuroendocrine pathologies and psychopathologies, such as depression and anxiety. This happens because the effects of glucocorticoids are mediated by intracellular receptors, such as glucocorticoid receptors. In this process, cortisol occupies the central place in the investigation to evaluate cases of hyperactivity or hypoactivity of the HPA axis.. When it comes to the methods to assess cortisol, the most commonly used is salivary cortisol. However, very recent studies have shown that assessing the RCA (Cortisol Arousal Response), which consists of a morning collection, can lead to several misconceptions suggesting that the cortisol curve is the most appropriate to obtain a more adequate response to cortisol variability. In this context, we sought to identify child stress from a study with children from 8 to 14 years of age using the ESI and the cortisol curve at three points (morning, afternoon and night) that allowed us to understand a little about the psycho-neuro-endocrinology of childhood stress. This study will contribute to the reflection on the development of preventive, direct and awareness-raising approaches for parents and caregivers, in addition to questioning us about the role of public policies in this context. The results of this thesis demonstrated that the use of the ESI (Children's Stress Scale) applied to 206 participants of both sexes (85 from the female group) and (121 from the male group), and the salivary collection, four hundred and eighty-nine (489) saliva samples were able to identify acute and chronic stress. In addition, we calculated two Logistic model: the Binary Logistic model and the Ordered Logistic model. In the Binary Logistic model, we correlated the results of the ESI and the results of the cortisol curve, where the results were statistically significant. In the Ordered Logistic model, we correlated all phases of the ESI (Alert, Resistance, Near-Exhaustion and Exhaustion) with the three points of the cortisol curve (morning, afternoon and night) where the results were also statistically. The results of the present study allows us to provide opportunities for additional studies to investigate child stress resulting from adverse childhood experiences, in addition to the ESI and the cortisol curve, other methods of investigation to identify child stress.
