Smartphone Screen Time and Physical Activity in a Sample of Czech and Slovak Secondary School Male Students

Summary/Abstract: Excessive use of smartphones can cause a decrease in physical activity. The present study aims at analysing and comparing the relationship between smartphone screen time and physical activ- ity in a sample of Czech and Slovak secondary school male students. The survey instrument (non- standardised) for measuring smartphone screen time and physical activity was intentional sam- pling of 1225 Czech and Slovak secondary school male students (aged 17.50 ± .65 years) who at- tended the last year of secondary schools. Chi-square test (χ2) and descriptive statistics were used to analyse and compare the data. Determining the relationship between smartphone screen time and physical activity was carried out for 9 months. After analysing the data, it turned out that 42.12% (n = 516) of the survey group pointed to 1 to 3 hours/ day of smartphone screen time (p ˂ 0.01). When evaluating their smartphone screen time, the survey group (n = 1225) considered it as adequate (58.21%, n = 713) (p ˂ 0.01). In terms of the smartphone screen time activity, the survey group (n = 1225) preferred social networking services (53.58%, n = 656) (p ˂ 0.01). Smartphone apps are adequate tools not only to improve quality of life, but also to promote lei- sure-time physical activity among adolescent boys.
