Sedentary behavior and health-related quality of life in adolescents

Abstract

Health-related quality of life (HRQoL) represents the perception of each person about different aspects of their lives in the health context (physical, psychological, social environment and interpersonal relationships). Among adolescents, HRQoL can change considering habits adopted in this phase of life. This study analyzed the association between time used on different sedentary behaviors (SB) and HRQoL in adolescents. This is a cross-sectional epidemiological study with adolescents between 10 - 15 years of age. The SB was measured using a questionnaire (n = 1,455 adolescents) and accelerometer (n = 844 adolescents), and HRQoL using KIDSCREEN - 27. Time on videogames/cell phones/tablets was inversely associated with overall HRQoL (β = -0.021; 95%CI: -0.026; -0.006), psychological well-being (β = -0.030; 95%CI: -0.050; -0.010), peer social support (β = -0.041; 95%CI: -0.066; -0.016) and school environment (β = -0.033; 95%CI: -0.056; -0.010) scores. Screen time was inversely associated with the school environment score (β = -0.011; 95%CI: -0.020; -0.003). Computer time was positively associated with the psychological well-being (β = 0.025; 95%CI: 0.006; 0.043) and peer social support scores (β = 0.029; 95%CI: 0.004; 0.053). It concluded that adolescents with more screen time had lower HRQoL. However, theses associations varied with the type and method of SB measurement and the HRQoL dimension.

Association between Different Domains of Sedentary Behavior and Health-Related Quality of Life in Adults: A Longitudinal Study

“…Prolonged periods of time engaged in screen activities (e.g., watching TV, using computers, smartphones, and tablets) also contribute to SB [ 7 , 8 , 9 ]. A previous study indicated that approximately 71% of adolescents from Brazil demonstrated excessive screen time [ 7 ].…”

“…), most of the studies assessed SB only by TV time [ 7 ]. Excessive screen time may negatively impact health-related quality of life (HRQoL) [ 8 , 10 ]. Adults and adolescents that spent long stretches of time on screen devices presented unfavorable dietary habits, as well as impaired physical and mental health (e.g., anxiety, headaches, perceived stress) and decreased HRQoL [ 9 , 11 , 12 , 13 ].…”

“…SB is a modifiable health behavior that has been investigated mainly for its high prevalence at a global level and its consequences for health [ 19 ]. Previous studies evidenced the relationship between SB and objective measures of health, such as obesity [ 3 , 20 ] and mental health (i.e., depression and anxiety [ 21 ]), while little is known about its influence on the HRQoL in adults as an important health indicator [ 8 ]. Studies that investigated the HRQoL, while considering its different domains, most conducted associations analyses taking into account only the physical activity practiced or insufficient physical activity levels, without considering the SB [ 22 , 23 ].…”

Estudos Multidisciplinares Sobre Saúde Da Criança E Do Adolescente

“…Embora se reconheça que a tecnologia faz parte do social e anular seu uso é uma pretensão que parece estar na esfera do impossível, é preciso perceber que a problemática está na forma que é utilizada e não na tecnologia propriamente dita. Assim, destaca-se a relevância da presença, da responsabilização e da mediação dos pais e responsáveis no controle do uso de telas, visto que a criança ainda não possui a capacidade de decidir sobre suas atitudes e sobre o que é melhor para si (Lucena et al, 2022).…”

An Explanatory Model of the Relationships between Physical Activity, Social Support and Screen Time among Adolescents

“…Lucena et al [ 36 ] found a positive relationship between “SS and peer group” and ST. The measurement of the social variable was with the KIDSCREEN-27 instrument, which asks about SS but in a generalized way, with no specific item on PA.…”
