With the wide use of screen media, screen exposure shows a trend of younger age, and the screen exposure of children and adolescents has become a global public health issue of concern. Childhood and adolescence are important stages of growth and development, as well as critical periods of cognitive ability, emotional development and socialization. Previous studies have shown that screen time is closely related to the mental health of children and adolescents, but few studies have focused on the correlation between screen content and their mental health. The screen content for children and adolescents mainly comes from traditional TV and emerging interactive electronic media. Children and adolescents are highly sensitive to screen content. This paper summarizes the current situation of screen content for children and adolescents and reviews the correlation between screen content and their mental health issues. It also reveals the potential mechanism of the correlation between the two to provide a theoretical basis for the selection and supervision of screen content for children and adolescents.
