Item Avaliação dos níveis de ansiedade em estudantes universitários(Universidade Brasil, 2021) Meneses, Aline Martins Diolindo; Santos, Laurita dos; Amaral, Marcelo MagriIntroduction: University admission is considered an anxiety generating experience to students due to the educational method transition stage from High School to University. Anxiety is a psychopathology incident in University students in which the symptomatology affects the formal learning construction, generating psychological illness. Scientific studies show a higher incidence of anxiety disorders in the health field students compared to the general population, pointing out the need for IES’ to evaluate the students’ psychological conditions, offering support services. Goal: Assess the anxiety signs and symptoms and its correlation with sociodemographic and lifestyle characteristics in University students. Methods: It is about an analytical and cross sectional study, conducted with 120 University students. The data was collectedthrough the following instruments: Sociodemographic and lifestyle questionnaire, BeckAnxiety Inventory (BAI) and saliva collection and salivary cortisol dosage. The researchwas approved by the Ethics and Research Committee of Universidade Brasil, under the opinion number 3.732.897. Results: A total of 120 students were a part of the study,106 being female and 14 being male students. The average age was 26.4 years old (Median:23.00; Standard deviation: 9.174; Min: 18; Max: 55). Out of the students, 77.5% are single and 76.7% have no kids. For the use of BAI, 16.7% of students had minimal anxiety, 13.3% had mild anxiety, 16.6% moderate anxiety and 53.3% severe anxiety. Regarding the dosage of salivary cortisol in the collected samples, 89.2% of students were within standard limits (under 0.736 µg / dL); 7.8% of students had cortisolvalues above the reference values. Conclusion: The data collected in the studyrevealeda high occurrence of students with signs and symptoms of anxiety disorders.The results reinforce the need for IES’ to include actions to identify students in psychological distress in their practices, concomitant with the adoption of pedagogicalpractices that envision their mental health.Item Variabilidade da frequência cardíaca e níveis de cortisol salivar entre policiais militares(Universidade Brasil, 2020) Araújo, Liliam Mendes de; Santos, Laurita dosThis study aims to validate the relationship between heart rate variability patterns and salivary cortisol levels in military police officers, based on measurements induced by the Trier social Stress Test (TSST). This is a cross-sectional experimental study, conducted between the months of February and November 2020, involving 30 male police officers in regular working activities for a year or more, aging over 18. The study excluded individuals with high blood pressure, diabetes, those carrying a pacemaker or a transplanted organ and teachers. The subjects were submitted to the TSST and their HRV and saliva (in order to measure cortisol levels) were taken at three moments: basal period and prior to the TSST, immediately after the test and 20 minutes after the second collection. For collecting the temporal series of RR intervals, we used the Polar®, v800 monitor. The project was approved by the Ethics and Research Committee of Universidade Brasil, CAAE: 85502418.0.0000.5494. The results showed that the TSST induced a physiological response which can be visualized in the cortisol concentrations (0.272 ± 0.221 e mean 0.220 µg/dL), p = 0.0001. With HRV analyzed by using linear time domain, frequency domain and non-linear methods, it was possible to identify that some variables show statistic difference (p< 0.05) among the distinct moments of the experimental protocol. Among the main contributions of this study, it was possible to point out the importance of cortisol, showing that it is related to HRV linear and non-linear measurements, as well as the strong positive linear correlation between the HRV variables. Thus, HRV used as an information tag of the physiological impacts caused by the experimental stress causes, in addition to being adopted as a complementary tool for police officers’ clinical evaluation, can also be an important biomarker to promote health. Promoting military police officers’ health is a big challenge, once strategies aimed at fighting stress related to police activities must be implemented so as to improve the quality of life and health of these professionals.
