Tempo de tela e nível de atividade física de crianças e adolescentes brasileiros : uma revisão integrativa.

Abstract

This integrative literature review aimed to analyze the screen time behavior and physical activity levels of Brazilian children in middle childhood and adolescence. A total of 17 studies published between 2021 and 2024 were selected, including six studies on screen time and 11 on physical activity levels, located in the BVS, SciELO, and PubMed databases, with samples of schoolchildren aged 6 to 18. The results revealed high levels of screen exposure. At the same time, low adherence to physical activity recommendations was observed, especially among girls. Most studies used self-reported questionnaires to measure screen time, while accelerometers were more commonly used to assess physical activity levels. A lack of standardization in assessment instruments and a scarcity of studies with children aged 6 to 10 were observed, limiting a deeper understanding of this developmental stage. Thus, it is concluded that there is high exposure to screens, low adherence to physical activity and a scarcity of studies with children, with screen time measured mainly by questionnaires and physical activity by direct and indirect methods.
