Abstract: Biomarkers such as oxytocin and cortisol are biological measures to quantify the stress level of an individual, which is related to several sociodemographic factors in many scientific publications. Some studies hypothesize that the response to stressful situations can vary depending on the ethnicity of each person, being the ethnicities that have suffered from historic trauma the most vulnerable ones to overcome those stressful situations and to create social bonds. In order to analyze the relationship between stress with different variables, this work combines previously published articles with data from a pilot study from the University of Maryland (UMD). An exploratory data analysis for each of the biomarkers using published databases, without the ethnicity variable is followed by a regression analysis to find the model that best fits the data. The outcomes show that variables like the heart rate of the individual are significant covariables, so adding those to the existing data collection protocol would improve the procedure and make it more suitable. Another objective of the present work is to analyze the significance of the ethnicity variable when measuring the changes in the stress, based on the biomarker¿s level. This goal has been affected by the current SARS-CoV-2/COVID-19 pandemic, and it has hinder the possibility to apply the regression models to the real project¿s data. Nevertheless, this work shows the process in a theoretical way. The application of the regression models to check the significance of the ethnicity to explain changes in stress is expected to be completed as soon as more observations are included in the database.
