The association between serum cortisol, thyroid profile, paraoxonase activity, arylesterase activity and anthropometric parameters of undergraduate students under examination stress

Stress caused due to examinations during any degree program and at educational level has been observed all levels so the present study was conducted investigate stress related final examination in undergraduate students with reference their academic performance. Fifty-four volunteers were divided into three groups, ( n = 18), according performance, that is, Group A low CGPA (⩽2.99), B average (⩾3.00–3.59) C high (⩾3.60) blood samples (3 ml) taken three-time intervals, pre-examination, post time interval, Department of Physiology, Government College University, Faisalabad. Anthropometric parameters like height, weight, pressure, heart rate body mass index (BMI) also determined. Blood cortisol thyroid hormones (triiodothyronine, T3; thyroxine, T4) stimulating hormone (TSH)) measured using ELISA based technique. Arylesterase activity (ARE) paraoxonase (PON-1) colorimetric method. The results showed overall increased pre-examination intervals as compared interval while PON-1 ARE significantly p < 0.05) decreased. With regards T4 TSH, a non-significant difference pre interval. It could be concluded from current semester system imposed group compare this find more already obtained other studied groups. Although, correlation between performance found but large scale trial multiple institutions throughout Pakistan is required exclude socioeconomic factors because belongs developing country.
