“…Previously, Reynaud et al (2018) showed that in preschoolers, adequate sleepers have better cognitive development and function while. Nonetheless, these results do not take into account the co‐dependence between movement behaviors (Laurent & Spencer, 2020). Conversely, using a compositional approach that accounts for the compositional nature of movement behaviors, Williams et al (2014) showed that being a physically active preschooler is associated with less sleep duration and more minutes awake at night, though differences in movement composition among adequate and short sleepers are still unknown.…”

Background: Accruing adequate daily amounts of time spent on movement behaviors (physical activity (PA), sedentary behavior (SB), and sleep) in childhood has been associated with positive short and long-term health outcomes.Nonetheless, how waking time is distributed across PA and SB among preschoolers who are short and adequate sleepers at night is unknown. Aim: This study investigated: (1) if there are differences in a movement behaviors composition among adequate and short nocturnal sleepers; and (2) the association between preschoolers' time spent in PA, SB, and sleep among adequate and short nocturnal sleepers. Methods: A total of 270 preschoolers (132 boys; 3.97 ± 0.81 years old; 15.48 ± 1.62 kg/m 2 ) participated in this study. PA and SB were assessed using accelerometry (model wGT3X). Sleep duration was assessed through a parental-proxy interview, and preschoolers were stratified as short and adequate sleepers, according to attendance to international sleep duration guidelines. Compositional data analysis was used to explore the time-use patterns of behaviors among adequate and short sleepers.Results: Short sleepers spent 64 min less time asleep, accumulated 32 min in more sedentary time (p = .005, Cohen's d = 0.36, Bayes Factor: 6.17), and 24 min more in light PA (p = .0005, Cohen's d = 0.44, Bayes Factor: 46.37) compared to adequate sleepers.Conclusions: Being a short sleeper was associated with greater time spent in SB and light PA during their waking hours. The health implications of movement behaviors composition among short sleep preschoolers should be further investigated. | INTRODUCTIONAccruing adequate amounts of time spent on physical activity (PA), sedentary behavior (SB), and sleep in childhood has been associated with positive short and longterm health outcomes (Carson et al., 2017;Carson et al., 2019). PA, SB, and sleep are movement behaviors that comprise a movement continuum that children are engaged in during 24 h (Tremblay et al., 2017). The World Health Organization (2020) recommends that 3 and 4 years-old preschoolers should accumulate 180 min of total PA, with at least 60 min of moderate-tovigorous-physical activity (MVPA), no more than 60 min in screen time during the day, and adequate sleep

“…Lower levels of sedentary behavior and higher levels of physical activity have been beneficially associated with sleep measures in adults, and there is some evidence that sleep can positively influence physical activity levels [ 10 , 11 ]. Although relations between movement behaviors and sleep in early childhood have been inconsistent, studies have been limited and most have solely examined overnight sleep—often not taking daytime sleep into account in analyses [ 12 , 13 ]. It is possible that napping could contribute to increased feelings of energy and motivation for movement, and high levels of movement could in turn improve the quantity and quality of nap sleep [ 14 ].…”

The purpose of this micro-longitudinal study was to explore daily associations between daytime movement behaviors (sedentary time and physical activity) and nap sleep in young children. In 298 children (age = 51.0 ± 9.6 months, 43.6% female), wrist-based actigraphy (mean wear time = 10 days) assessed sedentary time, total physical activity, and provided an estimate of nap sleep duration and efficiency. Multilevel logistic and linear regression models were used to examine temporal within-person relations between wake behaviors and nap sleep, and adjusted for overnight sleep duration between days of interest, age, sex, and socioeconomic status. Movement behaviors were not related to the likelihood of next-day napping, but when children were less sedentary (OR = 0.96; p < 0.001) or more active (OR = 1.01; p = 0.001) in the morning, they were more likely to nap that same day. Movement behaviors were not associated with nap sleep duration or efficiency. Conversely, on days children napped, they were less sedentary (B = −2.09, p < 0.001) and more active (B = 25.8, p < 0.001) the following day. Though napping and movement behaviors had some reciprocal relations, effect sizes in the present study were small. Further studies should examine children with more diverse sleep health and from different childcare settings.

“…While several correlates and determinants of movement behaviors have been explored in young childrensuch as demographic, physical health, social/cultural, and environmental factors [8][9][10] -relations between sleep and movement behaviors have only recently been considered. Although low sedentary time and high physical activity have been beneficially associated with sleep in adults [11][12][13] , two recent reviews concluded that among young children, evidence for a sleep benefit on sedentary time and physical activity is generally low 14,15 . However, studies in early childhood have primarily focused on overnight sleep using observational designs.…”

The objective was to determine if, in preschool-aged children, (1) nap habituality is associated with sedentary time and physical activity (movement behaviors), (2) nap physiology is associated with movement behaviors, and (3) if missing a nap, compared to taking a nap, affects movement behaviors on the same day and subsequent day. A within-subjects (44 children; 4.2 ± 0.6 years; 55.6% female), at-home study examined two experimental conditions (one afternoon each of nap- and wake-promotion with order counterbalanced) one week apart. Movement behaviors were derived from wrist-worn actigraphy (12.1 ± 3.1 days). Average movement behaviors were calculated from the overall study period with experimental days excluded. Movement behaviors were also extracted for the same day and the subsequent day of the two experimental conditions. Polysomnography was recorded during the nap-promoted condition. Children were classified as non-, intermediate-, or habitual-nappers. Although average movement behaviors were different between nap habituality groups, differences were not significant. There were no associations between movement behaviors and nap sleep stages, and no effects for nap condition or condition by nap habituality on same or next day movement behaviors. Findings do not suggest that naps and movement behaviors are related in children. Although a single missed nap was not detrimental to same or next day movement behaviors, future studies should explore effects of multiple days of subsequent nap restriction to examine potential cumulative effects.
