Background: Little is known about variation in meeting the 24-Hour Movement Guidelines (including physical activity [PA], sleep, and screen time [ST]) in early childhood. The aim was to evaluate sociodemographic differences in meeting the 24-Hour Movement Guidelines. Methods: Parents of 3-4 year old children reported sociodemographic information and ST. Sleep and PA were measured using accelerometry, and height and weight were objectively measured. The 24-Hour Movement Guidelines include daily PA (total PA: >= 3 h; including >= 1 h of moderate to vigorous), sleep (10-13 h), and ST (<= 1 h). Meeting guidelines by age, sex, race, poverty level, and weight status were assessed using chi-square and linear regression models. Results: Of 107 children, 57% were white and 26% lived in households at or below the poverty level. Most children met the PA (91.5%) and sleep (86.9%) guidelines, but few met ST (14.0%) or all 3 (11.3%) guidelines. African American children and children who lived at or below the poverty level were less likely to meet the sleep, ST, and all 3 guidelines compared with others (P < .01 for all). There were no other differences. Conclusion: These results suggest future interventions should focus on reducing differences in movement, namely in sleep and ST.
