Abstract

 Introduction: The accomplished studies show that stress can cause changes in biochemical and physiological parameters in healthy people. Materials & Methods: The present study was a cross sectional study conducted on 50 healthy university students selected randomly. Serum and urinary free cortisol was measured by immunoassay a month (control) before the examinations. Statistical analysis was performed using SPSS software version 11.5. The significance of differences was considered P<0.05.Findings: The average of systolic blood diastolic BLOOD PRESSUREs in the control group were 110.70±9.25 (mmHg), 73±8.97 (mmHg), respectively, while in the case group, 30 minutes prior to the examinations, they were 120.20±11.29 (mmHg), and 77.6±8.76 (mmHg), but immediately after the exams 108.80±9.97 (mmHg), 73.2±6.39 (mmHg). There was a statistical significance between the three groups. Also the average of serum and urinary cortisol concentrations in the control group was 151.83±48.86 (mg/lit), 133.03±47.1 (mg/lit), 30 minutes prior to examination 201.13±62.46 (mg/lit), 175.10±44.99 (mg/lit) and immediately after the examinations 141.48 ±49.25 (mg/lit), 165.98±46.08 (mg/lit) respectively. There was also a statistical significance among the three groups. Discussion &Conclusion: Examination is a potent stressor in students. It causes biochemical and physiological changes such as enhancement of BLOOD PRESSURE, serum and urinary cortisol.
