Abstract Background More screen time (ST) is associated with dysregulation of the individual biological systems (cardiovascular, immune, metabolic, and neuroendocrine) involved in stress response youth. However, its relationship allostatic load (AL), a measure cumulative physiological response, unclear Purpose To investigate associations between ST types AL outcomes youth to explore sociodemographic behavioral moderators these relationships. Methods Cross-sectional data were from 1053 US aged 12-17 years (Mage = 14.20; 54% male; 21% Hispanic) 2015-2018 National Health Nutrition Examination Survey (NHANES). was assessed as watching TV/videos computer use/playing games. measured using 7 biomarkers across 3 systems: cardiovascular (systolic diastolic blood pressure, heart rate), immune (C-reactive protein), metabolic (body mass index, glycohemoglobin, high-density lipoprotein). Weighted multivariable regression models whether predicted composite subsystem metabolic) scores. Moderation by age, sex, income, race/ethnicity, physical activity explored. Results A 1-hour/day increase 4% mean score (incident rate ratio 1.040; 95% CI 1.008, 1.073; P .015), while use/gaming showed no significant (P’s > .05). Age moderated TV/videos-AL association (P .009), older having higher Conclusions spent Prospective studies are needed determine causal pathways potential intervention targets
