Influence of physical activity and screen time on sleep quality in primary school students

In a society where, sedentary lifestyles and the use of technological screens are on the rise, students' lifestyle is being significantly affected. In fact, nowadays many students experience various sleep problems, and two of its main factors may be physical activity and the use of technological screens. In this sense, this research aimed to analyze the influence of students' physical activity and the screen time on sleep quality of students. The participants were 28 students in 5th and 6th grade of primary school. They wore ActiGraph WGT3X-BT accelerometers for one week to collect data related to physical activity and sleep patterns. Additionally, a survey was conducted to assess their use of technological screens. The collected data were analyzed, with a focus on differences by sex. Correlations between these parameters were also analyzed. The analysis revealed no significant correlation between physical activity and sleep quality. However, a significant correlation was observed between screen time and sleep quality. This finding highlights the importance of continued research in these areas to enhance the wellbeing and sleep quality of students.
