Background: Problematic internet use (PIU) is continuous failure to control the
use of the internet by individuals themselves along with the impairment of their lives in important
dimensions such as health, family and business. PIU causes psychological, social and
physical health problems especially among young people.
Objective: This study aimed to investigate the relationship between PIU, sleep quality and
academic achievement in Turkish university students.
Methods: The study sample consisted of 912 university students. Data were collected using
the Personal Information Form, Pittsburgh Sleep Quality Index, and Problematic Internet Use
Results: The percentage of the sample who used the internet every day was 70.7%. The
mean length of the internet use in 54.4% of the students varied from 61-120 minutes. Poor
sleep quality was reported by 78.9% of the students. Problematic internet use was more
common among the students who used the internet every day, who spent at least 121 minutes
on the internet at each use, who preferred to use the internet at night, whose academic
achievement score was <2,5 point and whose mothers had lower levels of education.
Conclusion: Health professionals need to be aware the effects of today's developing technologies
on young people’s health and they should inform young people about the consequences
of heavy use of the internet.
