^aAdjusted for age, race, gender, student status, college graduate, parental status, ability to live on income, depressive symptoms, depression diagnosis (ever), breakfast consumption, fast food consumption, total energy intake, consumption of sugar-sweetened beverages, MVPA, screen time. Gender- and ethnic-specific analyses are not adjusted for gender or ethnicity, respectively.

^bP-values for presented beta coefficient or odds ratio.

^cP-values for an interaction term between gender and sleep (gender row) or ethnicity and sleep (ethnicity row).
