The association between internet addiction, sleep quality, and health-related quality of life among Iranian medical students.

Due to the increasing use of the internet in Iranian society, especially among students, and the importance of sleep quality (SQ) and quality of life (QOL), the present study examined the relationship between QOL, SQ, and internet addiction (IA) among medical science students. In the present descriptive-analytical study, the sample comprised Saveh University of Medical Sciences students who were studying in 2019. The survey included demographic information (i.e., age, gender, place of residence, field of study, semester, marital status, smoking status, daily exercise) and the 20-item Internet Addiction Test. From 285 distributed questionnaires, 279 individuals with a mean age of 21.01 years (SD ± 3.17) completed the survey. Findings indicated that students with IA had higher mean scores on (i) all physical dimensions concerning QOL (except for the physical pain) and (ii) all psychological dimensions of QOL. The findings will help national health authorities and planners in Iran design appropriate and effective interventions to improve student health and prevent IA.
