【Abstract】 Objective To investigate the prevalence of Internet addiction and screen time and its association with mental health among college students. Methods A total of 2 377 college students including freshman,sophomore and junior students were recruited by stratified random sampling. Questionnaire survey was conducted to collect information on Internet addiction and screen time. Psychological sub-health,anxiety and depressive symptoms were measured by the Multidimensional Sub-health Questionnaire of Adolescents( MSQA),Self-rating Anxiety Scale( SAS) and Self-rating Depression Scale( SDS),respectively. Multivariable logistic regression models were used to examine the association of Internet addiction,screen time and mental health. Results The self-reported rates of Internet addiction,screen time > 2 h /d on weekdays and screen time > 2 h /d on weekends were13. 4%,15. 6% and 45. 1%,respectively. About 18. 6%,13. 4% and 18. 9% of students had psychological sub-health,anxiety and depressive symptoms,respectively. Multivariable logistic regression analysis indicated that Internet addiction was risk factor for psychological sub-health,anxiety and depression symptoms( OR = 4. 46,95% CI = 3. 43- 5. 81; OR = 4. 34,95% CI = 3. 27- 5.76; OR = 3. 69,95% CI = 2. 84- 4. 80). Screen time > 2 h /d on weekdays was related to psychological sub-health( OR = 1. 45,95% CI = 1. 08- 1. 96). Conclusion Internet addiction and screen time are growing serious among college students. Internet addiction is significantly related to mental health,screen time > 2 h /d on weekdays is related to psychological sub-health,but this relation between screen time on weekends and mental health is not obvious.更多还原
