Racial/ethnic disparity in habitual sleep is modified by caloric intake in adolescents.

ABSTRACT:

Study objectives

We investigated the moderation of caloric intake on the association between race/ethnicity and habitual sleep in adolescents.

Methods

We analyzed the data obtained from 324 adolescents who completed the follow-up examination of the Penn State Child Cohort study. We collected actigraphy-measured sleep duration on 7 consecutive nights and computed their mean and standard deviation as habitual sleep duration (HSD) and habitual sleep variability (HSV), respectively. We also measured participants' daily intakes of total calorie, total fat, carbohydrates, and protein, through the Youth/Adolescent Food Frequency Questionnaire. Adjusted mean HSD and HSV among non-Hispanic whites and racial/ethnic minorities were compared by using analysis of covariance (ANCOVA), whi
