Abstract

Background: Mobile phones with internet access have become a necessity in today’s world. An increasing number of students have been buying and using smartphones across developed and developing nations. With the growing popularity and affordability of these gadgets, there is a rising concern over the problematic usage of mobile phones, an entity which is catching up in today’s technology-driven society. Excessive dependence on digital media has started to reveal its burgeoning side effects on the psychophysiological milieu of the students. Aims and Objectives: The objectives of the study were (1) to assess the perception levels of medical students about problematic internet usage, (2) to study the effect of problematic internet usage on depression, stress, and anxiety quotients, and (3). to study the effect of problematic internet usage on heart rate and blood pressure (BP) during digital time out.
Materials and Methods: A cross sectional study design was used to conduct the study among the students of a medical college. Semi-structured, pre-tested questionnaires were developed and administered to the study population after obtaining informed consent. The questionnaire consisted of socio-demographic details of the medical students, questions based on pattern of internet usage and perception of problematic usage. Chen’s Internet Addiction Scale (CIAS) and depression, anxiety, and stress scale 21 Scale were used to assess internet addiction (IA) and depression, anxiety, and stress levels, respectively. Physiological parameters such as heart rate and BP components were recorded with the fully automated digital BP monitors certified by European Hypertension Society. Data were tabulated using Microsoft Excel 2010 and SPSS software (Version 24). P ≤ 0.05 was considered statistically significant.
Results: The total prevalence rate of IA was 44%, out of which female students had higher scores (52%) compared to males (31%). About 85% were aware of the entity “problematic internet usage.” There was a significant correlation r (199) = 0.538 between IA and stress with P = 0.0001. A marginally significant correlation r (199) = 0.472 was found between IA and depression with P = 0.11. A positive trend was seen between IA and anxiety, r (199) = 0.443 but it was not significant (P = 0.73). There was no significant correlation between IA score and basal physiological variables such as heart rate and BP. However, during digital time out, there was a net 3.7% increase in heart rate which was statistically significant. Although the systolic and diastolic components of blood pressure showed changes, they were statistically insignificant. Conclusion: Mobile phones with internet, influence medical students’ lives in numerous ways. The difference in prevalence,rates of IA is largely due to the different scales used for,assessment. Significant psychological and physiological,changes are associated with problematic internet usage.,The medical curriculum should include “problematic,internet usage” during the introductory year of the course,so as to expose the students to this entity and improves ,
