Hubungan Intensitas Penggunaan Media Sosial dengan Aktivitas Fisik pada Remaja di SMA Swasta Perguruan Al Azhar Medan

Abstract

The rapid development of digital technology has significantly transformed adolescents’ lifestyles. Increased time spent interacting with social media is feared to negatively impact adolescents’ levels of physical activity. Previous studies have shown that each additional hour of social media use is associated with a 30-minute decrease in moderate to vigorous physical activity. This study aims to examine the relationship between the intensity of social media usage and physical activity among adolescents at SMA Swasta Perguruan Al Azhar Medan. A quantitative study with a cross-sectional approach was conducted on 85 students selected through proportional random sampling, using a questionnaire for data collection. Data analysis utilized the Spearman correlation test to determine the strength and direction of the relationship between two variables. The results showed that the intensity of social media usage fell into the very high category for 55,3% of respondents (47 students), while physical activity levels were in the moderate category for 52,9% of respondents (45 students). The Spearman correlation analysis indicated a significant negative relationship between social media usage intensity and physical activity levels, with r = -0.440 and a p-value of 0.001 (<0.05). This finding suggests that higher social media usage intensity is associated with lower levels of physical activity among adolescents. The study underscores the need for interventions to raise awareness about the importance of physical activity among adolescent and better time management in social media usage.
