Background: Sedentary lifestyles and ultra-processed food (UPF) consumption contribute to a high prevalence of overweight and obesity among adolescents. Screen time may be associated with higher UPF consumption and affect eating behaviors substantially.
Objective: The aim of this study was to explore adolescents' perceptions, attitudes, and motivations concerning the consumption of UPF when using screens; investigate their perceived educational needs regarding nutrition; and explore their knowledge about UPF.
