Abstract

Early childhood is a vital time for cognitive development and to establish healthy behaviors such as physical activity (PA), sleep, and limited screen time (24-hr behaviors).

PURPOSE: To determine relations between compliance of 24-hr movement behavior guidelines and receptive vocabulary in preschool children and explore potential socio-demographic effect modifiers.

METHODS: Children (n = 233, 50.8 ± 9.5 months, 46.6% female) wore accelerometers for 9.5 ± 3.4 days and 9.7 ± 3.4 nights to estimate PA and sleep. Child’s age, sex, race, SES, and screen time were parent reported. Receptive vocabulary was assessed with the Peabody Picture Vocabulary Test (PPVT). All models included an interaction between the behavior compliance variable and race and were adjusted for age, sex, and SES.

RESULTS: Meeting the full guidelines was positively associated with PPVT scores (weekdays: B = 11.0, p = 0.014; weekends: B = 11.9, p = 0.005). However, among children identified as 2+ races, meeting the full guidelines was negatively associated with vocabulary (weekdays: B = -29.2, p = 0.037; weekends: B = -30.1, p = 0.012). In all models, age was positively, and SES was inversely associated with vocabulary. Meeting PA, screen time, and sleep recommendations when explored separately were not associated with performance.

CONCLUSION: Independent of age, sex, and SES, compliance with 24-hr behavior guidelines was associated with higher receptive vocabulary. Some relations were modified by race suggesting that engaging in health behaviors does not have the same influence on cognitive development. These considerations may be important health intervention designs targeting cognitive development.
