BACKGROUND As per global reports, India has seen the largest growth in use of Internet in 2019. Therefore, it has become crucial to understand how Internet affects our life. There is significant variation in the way Internet is used worldwide. The mechanisms and causal relationships are not very clear. Not many studies on Internet addiction have been done in India. Hence this study has been done to assess the effect of Internet on the sleep pattern of students in their late adolescence, as they are most vulnerable to the effects of Internet at this age. OBJECTIVE 1. To find the extent of problematic Internet use in first year medical students 2. To explore its effects on cognition and sleep. METHODS 100 students of BMCRI, aged 17-20 years were administered 2 questionnaires – Davis online cognition scale (DOCS) and Pittsburg Sleep Quality Index Questionnaire (PSQI) to assess Internet addiction and sleep respectively. RESULTS Out of 100 medical students, Problematic Internet usage/ PIU was found in 46% students with slight preponderance in males. 84% students had good sleep. There was significant positive correlation of DOCS scores with its all four cognitive dimensions/subscales - social comfort, loneliness/depression, diminished impulse control and distraction (r≥ 0.9, p CONCLUSIONS 46% of the medical students showed problematic Internet usage with significant correlation with distraction, impulsivity, depression/ loneliness and dependence on Internet for social comfort. However, sleep was good in the study population with no significant correlation with PIU. Thus, contrary to popular belief, judicious use of Internet may not lead to maladaptive patterns of sleep. The psychosocial factors linked to Internet use need to be further explored in more diverse groups with a deeper insight into its mechanism, effects, individual variation and regulation. This may help alleviate the adverse effects on Internet on human cognition. CLINICALTRIAL N/A |
