Examining the impact of physical activity (PA) and nutrition policies and interventions in childcare and preschool settings on PA levels, consumption of healthier foods and body weight outcomes.
Given the widespread use of out-of-home childcare facilities in Canada, and the considerable amount of time spent by preschoolers in these environments, this setting has great potential for the promotion of healthier weights.1 As such, development of policies and interventions aimed at promoting healthy physical activity (PA) and/or nutrition environments in this setting may be a promising strategy in the prevention of overweight and obesity. This evidence synthesis explores the effectiveness of PA and nutrition childcare policies and interventions on PA levels, consumption of healthier foods, and body weight outcomes.
- Findings from this synthesis indicate that childcare PA and nutrition interventions can result in positive outcomes related to PA levels and consumption of healthier foods. Positive outcomes related to body weight were limited, potentially due to short durations between intervention and follow-up measures.
- Relevant factors identified within reviews to successfully increase PA levels included increasing the availability and quality of play equipment (3, 4, 5), allocating time for organized PA sessions (3), staff education and training (3), integrating opportunities for PA into classroom curriculum (2, 3), and PA sessions that lasted at least 30 minutes (5).
- Strategies identified within reviews as successfully increasing consumption of healthier foods often included one or more of the following strategies: modifying foodservice practices (2), offering training workshops to staff (5), and classroom-based education for students (2).
- Additional research is required at the policy level that clearly measures the impact of existing childcare policies on outcomes of interest, in addition to examining policy implementation factors. Given the paucity of research focused on Canadian childcare settings, future studies in this area would be especially useful.
