Background: Despite the growing epidemic of problematic Internet use (PIU), little information
is available on PIU and related factors in Iran.
Methods: This cross-sectional study was conducted on 4261 university students among 13
universities throughout the country in 2017. The data collection tool included demographic
characteristics, the status of using the Internet, social media, computer games, tobacco, alcohol,
and illicit drugs, suicide ideation and attempt, and unprotected sex. PIU was measured using the
15-item PIU questionnaire. The status of general health was evaluated using the 28-item general
health questionnaire (GHQ) questionnaire. The simple and multiple logistic regression analysis
were used to measure the crude and adjusted associations between various factors and PIU.
Results: Of 4261 university students, 55.9% were female, 13.5% were smokers, 4.9% were
drug abusers, 7.9% were alcohol abusers, 7.8% had unprotected sex in the past year, 7.4%
had suicidal ideation in the past month, 1.7% had attempted suicide in the past year, and
27.3% suffered from PIU. Only 61.1% had normal health. In contrast, 30.9%, 7.2%, and 0.8%
had mild, moderate, and severe general health problems, respectively. There were significant
relationships between PIU and age group 20-24 vs. <20 years (odds ratio [OR] = 1.39; 95% CI:
1.06, 1.82), single vs, married (OR = 2.57; 95% CI: 1.85, 3.57), suicidal attempt (OR = 2.77;
95% CI: 1.47, 5.19), using online games (OR = 1.31; 95% CI: 1.07, 1.60), and poor general
health (OR = 12.14; 95% CI: 4.53, 32.54).
Conclusion: Nearly one-third of medical sciences students suffered from PIU. This unhealthy
behavior was associated with poor general health and elevated risk of suicidal behaviors. This
health-threatening behavior provides an early warning signal that deserves special attention,
otherwise, it may threaten both college students’ health and function.
