Insights
The Supporting Physical Activity in the Childcare Environment (SPACE) intervention aims to boost preschooler activity levels. Findings may inform childcare policies and curriculum adjustments for increased physical activity.
Area of Science:
- Child Health
- Pediatric Exercise Science
- Early Childhood Education
Background:
- Young children exhibit low physical activity levels in childcare settings.
- Preschoolers are more active outdoors, particularly in the initial minutes of play.
- Previous interventions using staff training or play equipment successfully increased activity.
Purpose of the Study:
- To detail the protocol, methods, and evaluation of the Supporting Physical Activity in the Childcare Environment (SPACE) intervention.
- To provide a foundation for future research on enhancing physical activity in childcare.
- To address the need for improved physical activity in early childhood education.
Main Methods:
- A cluster randomized controlled trial involving 22 childcare centers.
- An 8-week intervention combining shorter, frequent outdoor play, portable equipment, and staff training.
- Physical activity measured by accelerometers at baseline, post-intervention, and at 6- and 12-month follow-ups.
Main Results:
- The SPACE intervention is designed to increase physical activity in preschoolers.
- Secondary outcomes include evaluating effects on sedentary time, BMI, quality of life, and provider knowledge.
- The study employs rigorous methodology for reliable data collection.
Conclusions:
- The SPACE study seeks to elevate physical activity levels in childcare settings.
- Results may guide policymakers and childcare providers in modifying curricula and playtimes.
- This research contributes to understanding effective strategies for promoting childhood physical activity.
Background:
Young children are prone to low levels of physical activity in childcare. Researchers have identified that preschoolers tend to be more active outdoors than indoors, with higher activity levels occurring during the first 10 minutes of outdoor playtime. Additionally, interventions incorporating either staff training or the inclusion of play equipment have been effective at increasing children's activity in this setting. As such, the overarching objective of the Supporting Physical Activity in the Childcare Environment (SPACE) intervention is to improve the physical activity levels of preschoolers during childcare hours, utilizing a combination of the above components. The purpose of this manuscript is to provide a detailed account of the protocol, innovative methods, and evaluation plans used in the implementation of the SPACE study; in an effort to support the development of further research in this field.
Methods/Design:
The SPACE study, a cluster randomized controlled trial, involves 22 childcare centres randomly allocated to either the experimental (n = 11) or the control (n = 11) group. Childcare centres receiving the intervention will adopt an 8-week physical activity intervention with the following components: 1. shorter, more frequent bouts of outdoor playtime (4 × 30 min periods rather than 2 × 60 min periods); 2. new portable play equipment (e.g., obstacle course, balls); and, 3. staff training (1 × 4 hr workshop). Actical accelerometers will be used to assess total physical activity with measurements taken at baseline (i.e., week 0), immediately post-intervention (i.e., week 8), and at 6- and 12-month follow-up. As secondary objectives, we aim to evaluate the effectiveness of the intervention on preschoolers': a) sedentary time; b) standardized body mass index scores (percentiles); c) health-related quality of life; and childcare providers' physical activity-related knowledge and self-efficacy to implement physical activity.
Discussion:
The SPACE study aims to increase the low levels of physical activity observed within childcare centres. The findings of this work may be useful to policy makers and childcare providers to consider modifications to the current childcare curriculum and associated outdoor play time.
