Description
Background: Adolescent obesity affects nearly 1 in 5 U.S. teens and is influenced by behavioral and social factors. Excessive screen time and poor sleep are known contributors, but less is known about how these risks interact with socioeconomic status (SES) and household routines. Understanding these interactions is essential for designing effective, equitable interventions.
Methods: We conducted a literature review of peer-reviewed studies from the past five years exploring the relationship between screen time, sleep, and obesity among U.S. adolescents, with attention to the moderating roles of SES and family routines (e.g., parental monitoring, bedtime rules).
Results: High screen use and short sleep duration were consistently associated with higher BMI and increased risk of obesity. Adolescents from lower-SES backgrounds reported more screen time and worse sleep, often in homes with fewer protective routines. Some studies suggested that sleep mediates the relationship between screen time and obesity, while household rules may buffer these effects, though such pathways remain under-tested.
Conclusions: Our findings show the importance of considering family environment and socioeconomic context in adolescent obesity research. Targeting screen and sleep habits alone may be insufficient; incorporating household routines and social determinants may improve future interventions.
