We hypothesized that sleep quality mediates the association between pre-bedtime electronic screen media entertainment use and academic performance among college students.Methods: This was a cross-sectional survey with 1385 participants (age 19.99 ± 1.4 years [range, 17– 24 years] and 36.82% males) conducted at Shantou University. The levels of academic performance were based on self-reported academic class ranking from average grades of their last final major examinations. Poor sleep quality was defined as a total score of the Pittsburgh Sleep Quality Index > 7. The pre-bedtime prolonged electronic screen media use for entertainment (PESM-E) was defined as the use of electronic screen media for entertainment longer than 60 minutes/night after 10:00 p.m. during the past 6 months.Results: College students with pre-bedtime PESM-E were 1.28-fold more likely to have a poor academic performance than those who used electronic screen media less than 60 minutes (95% confidence interval [CI]: 1.04– 1.57, P=0.020). Furthermore, pre-bedtime PESM-E was significantly associated with poor sleep quality (adjusted odds ratio [AOR]=1.87, 95% CI: 1.27– 2.74, P=0.001) after controlling for confounders. Mediation model showed that poor sleep quality accounted for 53.08% of the effect of pre-bedtime PESM-E on lower levels of academic performance (Sobel Z=2.04, P=0.041).Conclusion: Pre-bedtime PESM-E is associated with poor academic performance in college students, and this association is mediated by poor sleep quality. Our findings highlight the importance of limiting the use of electronic screen media before bedtime in college students.Keywords: poor sleep quality, sleep, academic performance, electronic screen use, college students
