Incidence of Smartphone Addiction, Poor Sleep Quality and Daytime Sleepiness on Academic Performance of High School Students in Marrakech

Excessive use of smartphones has been associated with both poor sleep quality as well as daytime sleepiness. In the educational context, it is established that these factors often have an impact on the academic performance of students. This cross-sectional study is conducted to assess the impact of sleep quality in relation to the use of smartphones on academic performance among Moroccan high school students in the city of Marrakech. It involves 570 students of both sexes, aged 17 to 20 years. Participants answered a self-administered questionnaire assessing Smartphone Addiction (SA), Sleep Quality (SQ), and excessive Daytime Sleepiness (DS). The results show that smartphone addiction is positively correlated with poor sleep quality (r = 0.445; p = 0.000) and daytime sleepiness (r = 0.482; p = 0.000). In the same vein, academic performance is negatively correlated with smartphone addiction (r = -.144; p < 0.05), poor sleep quality (r = -0.074, p > 0.05), and daytime sleepiness (r = -0.073, p > 0.05). Smartphone addiction has proven to have a negative impact on sleep quality, daytime sleepiness, and academic performance of high school students. These results call on parents and school health officials to implement awareness campaigns aimed at promoting rational and moderate use of screens and healthy sleep among high school students.
