Objectively Measured Physical Activity and Sedentary Time of Suburban Toddlers Aged 12-36 Months

Correlates of Toddlers' Physical Activity Levels and Sedentary Behavior During Unstructured Outdoor Play in Early Childhood Education and Daycare Settings

Despite recent research showing that early childhood education and daycare settings (ECEC) have an important role in promoting toddlers' physical activity (PA), crucial information gaps remain regarding toddlers' PA and sedentary behavior (SB) in these outdoor settings. We aimed in this study to: (a) analyze PA patterns and SB during unstructured outdoor play time in preschool and daycare environments using accelerometry and systematic observation; (b) provide concurrent accelerometry and observational data to help validate the Observational System for Recording Physical Activity in Children-Preschool Version (OSRAC-P); and (c) examine individual, social and environmental correlates of PA and SB during toddlers' unstructured outdoor play time. We found that: (a) toddlers displayed high amounts of PA with no sex, BMI, and/or age differences in PA and SB levels,; (b) environmental variables (e.g., fixed equipment and playground density) were not associated with PA levels or SB intensity; (c) the OSRAC-P was a reliable and valid means of observing and analyzing toddlers' PA patterns during unstructured outdoor play time; and (e) different social patterns between boys and girls did not impact PA levels or patterns. Combining different measurement methods permitted an improved understanding of unstructured outdoor play in preschool and daycare settings.

Effect and process evaluation of a preschool-based intervention to promote an early childhood education and care teacher-parent partnership about healthy behaviours in children: Study protocol for the cluster randomised controlled trial CO-HEALTHY

BACKGROUND

Early Childhood Education and Care (ECEC) teachers at urban preschools are potential key figures to promote healthy behaviours in disadvantaged young children and to engage parents in lifestyle-related topics. An ECEC teacher-parent partnership regarding healthy behaviours may support parents and stimulate their children's development. However, it is not an easy task to establish such a collaboration and ECEC teachers need tools to communicate with parents about lifestyle-related topics. This paper describes the study protocol of a preschool-based intervention (CO-HEALTHY) to promote an ECEC teacher-parent partnership regarding healthy eating, physical (in)activity and sleeping behaviours in young children.

METHODS

A cluster randomised controlled trial will be performed at preschools in Amsterdam, the Netherlands. Preschools will be randomly allocated to an intervention or control group. The intervention consists of a toolkit with 10 parent-child activities and associated training for ECEC teachers. The activities were composed using the Intervention Mapping protocol. At intervention preschools, ECEC teachers will carry out the activities during standard contact moments. Parents will receive associated intervention materials and will be encouraged to perform similar parent-child activities at home. At control preschools, the toolkit and training will not be implemented. The primary outcome will be the teacher- and parent-reported partnership regarding healthy eating, physical (in)activity and sleeping behaviours in young children. The perceived partnership will be assessed by a questionnaire at baseline and at 6 months. In addition, short interviews with ECEC teachers will be held. Secondary outcomes include the knowledge, attitude, food- and activity-related practices of ECEC teachers and parents. Furthermore, children's eating, physical (in)activity and sleeping behaviours, and weight development will be assessed. A process evaluation of the intervention will be made.

DISCUSSION

The intervention aims to provide a practical tool for ECEC teachers at urban preschools to promote an ECEC teacher-parent partnership regarding a healthy lifestyle in young children.
