Relationship between Physical Activity, Screen Time, and Sleep Quantity and Quality in US Adolescents Aged 16⁻19.

ABSTRACT: Despite the health benefits associated with physical activity (PA), screen time reduction, and sleep quantity and quality, the relationships between PA, screen time, and sleep quantity and quality remain unclear in adolescents. The present study is a cross-sectional analysis of data from adolescents aged 16-19 years who participated in the 2005-2006 National Health and Nutrition Examination Survey (n = 542).
