Multivariable-adjusted associations of sleep duration and efficiency (per
interquartile increase) with adiposity outcomes. Results for adiposity
outcomes are shown per IQR of the following sleep exposures: duration
(55 minutes) and efficiency (6%). Models adjust for maternal education
and household income, season of measurement, and adolescent age, sex,
race and/or ethnicity, and puberty (Tanner stage). A, BMI
z score. B, DXA total fat mass index (in kilograms
per meter squared). C, DXA trunk fat index (in kilograms per meter
squared). D, Sum of subscapular and triceps skinfolds (millimeters). E,
Waist circumference (in centimeters).
