Description
Summary:Objectives and importance of study: Young children's outdoor play mostly occurs within the home-yard space, yet the influence of the home yard on preschoolers' outdoor play and physical activity is poorly understood. We investigated the relationships between home-yard features and home-based outdoor play and physical activity in preschoolers (2-5 years old). Study type: Cross-sectional observational study. Methods: The PLAY Spaces and Environments for Children's Physical Activity (PLAYCE) study (2015-2017) included 1596 children aged 2-5 years attending early childhood education and care (ECEC) services throughout metropolitan Perth, Western Australia. In this study, a subsample of 224 parents from the PLAYCE study completed an online questionnaire about home-yard features (yard size, lawn quality, natural features, fixed and portable play equipment, and flowers and vegetables/herbs). Accelerometers measured the duration of preschoolers' moderate-vigorous physical activity (MVPA) on non-ECEC days. Parent-reported outdoor play at home, sociodemographic factors and social environment factors were collected via the PLAYCE parent survey. Multiple linear regression models were used to determine associations between home-yard features and preschoolers' outdoor play and physical activity. Results: Children spent 68.9 (SD 2.2) minutes playing outdoors in the home yard per day, and 93.3 (SD 37.1) minutes in MVPA per day on non-ECEC days. After adjusting for child and parent factors, home-yard features positively associated with outdoor play included yard size, lawn quality, number of types of fixed and portable play equipment, natural features and play areas (all p ≤ 0.05). When all significant home-yard features were placed in a model, only the number of types of fixed play equipment was positively associated with minutes of outdoor play per day (β = 5.3, p < 0.001). After adjusting for sociodemographic factors, the number of types of portable play equipment in the yard was positively associated with MVPA minutes per day (β = 2.16, p = 0.019); however, this became nonsignificant after further adjusting for social environment factors. Conclusions: Features of the home-yard physical environment were positively associated with preschoolers' outdoor play and physical activity. Each additional type of fixed play equipment present was associated with an additional 5 minutes of outdoor play per day. These findings suggest that the home-yard space has the potential to facilitate increased outdoor play in young children. Further research is warranted to explore causal relationships between home-yard attributes and young children's outdoor play and physical activity.
