Objectives: To examine the association among 24-Hour Movement Guidelines and fundamental motor skills (FMS) in preschoolers. Design: Prospective cohort study with one-year follow-up. Methods: Parents of 3-4-year-old children reported child age, sex, race, and time spent viewing screens (hours/day). Accelerometers measured preschooler physical activity (PA) and sleep. The 24-Hour Movement Guidelines were examined (>= 3 h/day total PA including >= 1 h/day of moderate-to-vigorous [MVPA], 10-13 h/day of sleep, and <= 1 h/day of screen-time). Trained researchers administered the Test of Gross Motor Development-Third Edition (TGMD-3) to assess FMS. Linear regression was used to assess guidelines met and raw locomotor, ball skills, and total TGMD-3 scores with adjustment for covariates. Results: One hundred and seven preschoolers provided complete cross-sectional data, and 53 preschoolers provided complete longitudinal data. Of the 107 preschoolers, they were 3.4 +/- 0.6 years of age, 44% were male, 50% were White, and the mean age-and-sex adjusted TGMD-3 total score percentile was below average (41 +/- 22). Many preschoolers met the PA guideline (91%) and sleep guideline (83%), but few preschoolers met the screen-time guideline (8%) or all three guidelines (6%). MVPA was positively associated with locomotor and total TGMD-3 scores in cross-sectional analysis (p < 0.05 for all). Baseline PA, sleep, and screen-time were associated with total TGMD-3 score at follow-up (p < 0.05 for all). Meeting the screen-time guideline and all three guidelines at baseline were each positively associated with total TGMD-3 score at follow-up (p < 0.05 for all). Conclusions: Each movement behavior contributed to later FMS. Promotion of adequate movement behaviors is warranted for child health. (C) 2020 Sports Medicine Australia. Published by Elsevier Ltd.
