Background: The increasing prevalence of excessive screen time (ST) among children is a growing public health concern due the associated risk of overweight and obesity in children. Increasing ST among preschool-age children (2-5 years of age) has prompted several countries including the United States (US) to develop ST guidelines. In 2016, the American Academy of Pediatrics (AAP) released updated guidelines that encourage parents of preschool-age children to limit ST to < 1 hour per day. Objective: To explore the beliefs, attitudes, and practices of Brazilian-born immigrant mothers' living in the US related to their preschool-aged children's ST. Methods: Qualitative study with seven focus group discussions (FGDs) conducted with Brazilian immigrant mothers to gain an in-depth understanding of the research topics. All FGDs were audio-recorded and professionally transcribed verbatim. The Portuguese transcripts were analyzed using thematic analysis. Results: In total, 37 women participated in the FGDs. Analyses revealed that although most mothers expressed concerns for their children's ST, nearly all viewed ST as an acceptable part of children's daily lives. Furthermore, mothers perceived more benefits than disadvantages associated with ST. Mothers' positive beliefs (e.g., educational purposes, entertainment) and their perceived functional benefits of ST (e.g., ability to keep children occupied so tasks can be completed, regular communication with family outside the US) contributed to their acceptance of ST for their young children. Nevertheless, most mothers spoke of the need to find a balance between their children's ST and other activities, and reported using several parenting practices to manage ST including monitoring time and content, setting limits and rules, and prompting their children to do something else.
Conclusions:The present study provides new information on the beliefs, attitudes, and practices of Brazilian immigrant mothers living in the US related to their preschool-aged children's ST. Study findings revealed several potentially modifiable maternal beliefs and parenting practices that may provide important targets for parenting-and familybased interventions aimed at promoting adequate preschool-age children's ST.
