Assessment Of Examination Stress And HRV in Adolescents
Assessment Of Examination Stress And HRV
Keywords:
Examination Stress ,HRV,Student SuicideAbstract
Objective.The present study was designed to define and evaluate examination stress among ,adolescents in the age group of 12–18 years in relation to heart rate variability (HRV), an index of sympathovagal interplay, one of the sensitive neurophysiological axes to be influenced initially, when an individual is exposed to any stressor.Methods. Hari’s stress inventory for students was used to qualify examination stress was collected on 69 healthy school students, free from any acute or chronic ailment, one month and seven days before the start of final examinations along with acquisition of short – term HRV to profile the sympathovagal interplay, a sensitive index of both physical and mental stress. Results. The stress inventory depicted that the sample population was under an enhanced mental stress 7 days before the examination as compared to that observed 1 month before the ratios of HRV 1month and 7 days before the final examination. Significant appreciable difference could also be appreciated in the values of SDANN in time domain and amplitude of the waveforms in HF, LF on the frequency domain of HRV.Conclusion. An enhanced sympathetic outflow as discerned through increase in LF/HF ratio and LF power with a concomitant decrease in HF power along with significant decrease in SDANN values profiling a decreased vagal outflow of the student population denotes an autonomic neurophysiological status that needs a specialist attention in terms of proper and adequate guidance and counselling.
