The Correlation Between Screen Time, Sleep Quality, and Physical Fitness Among Grade VII Students

Abstract

This study aims to examine the relationship between screen time and sleep quality as well as physical fitness levels of seventh-grade students at SMP Negeri 1 Semarang. This research employed a quantitative approach with a correlational design. The population consisted of 287 students, and 74 students were selected as the sample using simple random sampling based on the Slovin formula with a 10% margin of error. Data were collected through questionnaires to measure screen time and sleep quality, as well as a physical fitness test to assess students’ fitness levels. Data were analyzed using Pearson Product Moment correlation at a significance level of 0.05. The results indicated a significant relationship between screen time and sleep quality (r = 0.234; p = 0.045) with a low correlation level, and a significant relationship between screen time and physical fitness levels (r = -0.354; p = 0.002) with a moderate correlation level. The coefficient of determination showed that screen time contributed 5.48% to sleep quality and 12.53% to physical fitness levels. Overall, screen time plays a significant role in students’ sleep quality and physical fitness levels.
