Screen time and allostatic load among youth: findings from the National Health and Nutrition Examination Survey, 2015-2018.

ABSTRACT:

Background

More screen time (ST) is associated with dysregulation of the individual biological systems (cardiovascular, immune, metabolic, and neuroendocrine) involved in the stress response in youth. However, its relationship with allostatic load (AL), a measure of the cumulative physiological stress response, is unclear in youth.

Purpose

To investigate the associations between ST types and AL outcomes in youth and to explore sociodemographic and behavioral moderators of these relationships.

Methods

Cross-sectional data were from 1053 US youth aged 12-17 years (Mage = 14.20; 54% male; 21% Hispanic) in the 2015-2018 National Health and Nutrition Examination Survey (NHANES). ST was assessed as watching TV/videos and computer use/playing computer games. AL was measured
