Abstract

Abstract: The prevalence of cardiovascular disease especially hypertension and coronary heart disease and its mortality showed a sharply increase worldwide. One risk factor of cardiovascular disease that well establish is mental stress. The prevalence of stress among medical students are high when compare with age matched peers. Many medical students who experience stress are unable to reach their educational target because they fail to adapt with the stressful and demanding environment. This study investigated the stress level, sleep quality, salivary midnight cortisol and heart rate value among medical students who enrolled first year medical phase at state Islamic University Maulana Malik Ibrahim Malang. Our findings were expected to develop new theoretical model explaining the pathway of stress in affecting cardiovascular function as a consequences of circadian misalignment and change of cortisol secretion. These results might be a valid material to evaluate the curriculum strategy and implementation. 48 medical students were participated in this research. The stress level was measured using the Student Life Stress Inventory questionnaire; the sleep quality graded with the Pittsburgh Sleep Quality Index questionnaire. Heart rate of the medical students were measured by placing and pressing the tip of the index finger and middle finger on the base of the thumb on the wrist. The cortisol concentration using a sample of medical students’ saliva was measured with ELISA Salivary Cortisol Kit DBC Canada CAN-C-290. The data obtained was processed using the descriptive and inferential statistics using paired t-test and path analysis. 33,3 % subject exposed to mild stress, 50% got moderate stress and 16,7% of them were suffering severe stress. All subject had a poor sleep quality. The average sleep duration among them was 4 hours. Most of them started to sleep after 10 p.m. Stress had a direct influence on circadian rhythm disorder (p = 0,023*). Stress had indirect influence on increasing heart rate (p=0,006**), where these effects were mediated by increasing cortisol concentration in the midnight (p = 0,041*).Medical students were susceptible to stress and had a poor sleep quality. This academic stress can be determine by the increase of midnight cortisol, cause circadian misalignment and might affect cardiovascular function.
