(1) Background: Participation in physical activity is crucial for the healthy growth and development of young children. More robust measurement of environmental influences on children’s physical activity in early childhood education and care (ECEC) settings may help resolve inconsistencies in the literature. This study evaluated the reliability of an environmental audit and educator practice survey for assessing ECEC physical, policy, and social environments related to young children’s physical activity. (2) Methods: A convenience sample of 20 ECEC centres participated in this PLAYCE (Play Spaces and Environments for Children’s Physical Activity) sub-study. Trained auditors conducted audits and educators completed surveys, two weeks apart. Test-retest reliability of the survey (n = 32), inter-rater (n = 20 pairs) and intra-rater reliability (n = 38) of the audit was assessed using intra-class correlation coefficients (ICCs), Kappa statistics and percent agreement. (3) Results: Intra-rater and inter-rater reliability ICCs for outdoor equipment, spaces and features were good to excellent (ICC = 0.70–0.94), while ratings for indoor equipment, media and spaces varied from fair to excellent (ICC = 0.46–0.78). The majority of items were rated by Kappa as moderate or above for intra-rater, inter-rater and survey test-retest reliability. (4) Conclusions: The PLAYCE Study instruments provide reliable measures of ECEC physical activity environments which can help to better understand influences on young children’s physical activity.

Background: To examine the relationship between attributes of early childhood education and care (ECEC) settings and children’s physical activity and sedentary behavior. Methods: Cross-sectional study involving 490 children aged 2–5 years from 11 ECECs. The ECEC routine, size of the outdoor environment, and time spent in the outdoor environment were calculated for each center. Children’s physical activity and sedentary time were measured using accelerometers. Multivariate linear regressions were used to examine associations of the attributes of ECEC centers with the outcome variables, adjusting for the effects of center clustering and gender. Results: Children in ECECs that offered free routines (where children can move freely between indoor and outdoor environments) had lower levels of sedentary time (28.27 min/h vs 33.15 min/h; P = .001) and spent more time in total physical activity (7.99 min/h vs 6.57 min/h; P = .008) and moderate- to vigorous-intensity physical activity (9.49 min/h vs 7.31 min/h; P = .008). Children in ECECs with an outdoor environment >400 m2 had less sedentary time (28.94 min/h vs 32.42 min/h; P = .012) than those with areas <400 m2. Conclusion: Modifiable practices such as offering a free routine and increasing time spent in outdoor environments could potentially offer an easy and sustainable way for ECEC centers to promote physical activity and reduce sedentary time among children.

Background: This study examined the associations between environmental characteristics of early childhood education and care (ECEC) centers and 1-year change in toddlers’ physical activity and sedentary behavior while at the centers. Methods: Data from 292 toddlers from the GET-UP! study were analyzed. Environmental characteristics of ECEC centers were rated using the Infant/Toddler Environment Rating Scale-revised edition at baseline. Children’s physical activity and sedentary behavior in the centers were assessed using activPAL devices, at baseline and at 1-year follow-up. Linear mixed models were performed to examine the associations between the environmental characteristics and change in the proportion of time spent in physical activity and sedentary behavior. Results: Compared with baseline, children spent a higher proportion of time in sedentary behavior (sitting) but a lower proportion of time in standing and physical activity (stepping) while at ECEC centers, at 1-year follow-up. The environmental characteristics “interaction” (B = −1.39; P = .01) and “program structure” (B = −1.15; P = .04) were negatively associated with change in the proportion of time spent in physical activity. Conclusion: Better “interaction” and “program structure” may preclude children’s physical activity from declining over time and may be considered important features to target in future interventions in ECEC centers aiming at promoting active lifestyles.

Early childhood education and care (ECEC) environments influence children’s early development and habits that track across a lifespan. The purpose of this study was to explore the impact of COVID-19 government-mandated guidelines on physical activity (PA) and eating environments in ECEC settings. This cross-sectional study involved the recruitment of 19 ECEC centers pre-COVID (2019) and 15 ECEC centers during COVID (2020) in Alberta, Canada (n = 34 ECEC centers; n = 83 educators; n = 361 preschoolers). Educators completed the CHEERS (Creating Healthy Eating and activity Environments Survey) and MEQ (Mindful Eating Questionnaire) self-audit tools while GT3X+ ActiGraph accelerometers measured preschooler PA. The CHEERS healthy eating environment subscale was greater during COVID-19 (5.97 ± 0.52; 5.80 ± 0.62; p = 0.02) and the overall score positively correlated with the MEQ score (r = 0.20; p = 0.002). Preschoolers exhibited greater hourly step counts (800 ± 189; 649 ± 185), moderate-to-vigorous PA (MVPA) (9.3 ± 3.0 min/h; 7.9 ± 3.2 min/h) and lower sedentary times (42.4 ± 3.9 min/h; 44.1 ± 4.9 min/h) during COVID-19 compared to pre-COVID, respectively (p < 0.05). These findings suggest the eating environment and indices of child physical activity were better in 2020, which could possibly be attributed to a change in government-mandated COVID-19 guideline policy.

Abstract Movement behaviors (physical activity, sedentary behavior (including screen time), and sleep) have been impacted by the COVID-19 pandemic. We aimed to report changes in and factors influencing movement behaviors during COVID-19 among Latin American/Latino children aged 1 to 5 years in Chile, Mexico, and the USA. We conducted a cross-sectional study between April and August 2020. Caregivers reported changes in movement behaviors and provided information about family and household characteristics. In total, 4,136 children (mean age [SD], 3.1 [1.4] years; 51% boys). The proportion of children who met the WHO Guidelines decreased significantly in all countries, with large declines in meeting the physical activity and screen time guidelines. Factors associated with changes were being an older child, unable to attend an early childhood education and care service, higher parental education levels, not having the opportunity to play with someone, and not having access to spaces to play. During COVID-19, Latino parents reported changes in physical activity, screen time, and sleep quality among their toddlers and preschoolers. The findings highlight the need to minimize disparities faced by families by providing access to early childhood education and care and safe places for children to play.
