Objective Measures of the Built Environment and Physical Activity in Children: From Walkability to Moveability
Features of the built environment that may influence physical activity (PA) levels are commonly captured using a so-called walkability index. Since such indices typically describe opportunities for walking in everyday life of adults, they might not be applicable to assess urban opportunities for PA in children. Particularly, the spatial availability of recreational facilities may have an impact on PA in children and should be additionally considered. We linked individual data of 400 2- to 9-year-old children recruited in the European IDEFICS study to geographic data of one German study region, based on individual network-dependent neighborhoods. Environmental features of the walkability concept and the availability of recreational facilities, i.e. playgrounds, green spaces, and parks, were measured. Relevant features were combined to a moveability index that should capture urban opportunities for PA in children. A gamma log-regression model was used to model linear and non-linear effects of individual variables on accelerometer-based moderate-to-vigorous physical activity (MVPA) stratified by pre-school children (<6 years) and school children (≥6 years). Single environmental features and the resulting indices were separately included into the model to investigate the effect of each variable on MVPA. In school children, commonly used features such as residential density (βˆ=0.5⋅10−4,p=0.02), intersection density (βˆ=0.003,p=0.04), and public transit density (βˆ=0.037,p=0.01) showed a positive effect on MVPA, while land use mix revealed a negative effect on MVPA (βˆ=−0.173,p=0.13). In particular, playground density (βˆ=0.048,p=0.01) and density of public open spaces, i.e., playgrounds and parks combined (βˆ=0.040,p=0.01), showed positive effects on MVPA. However, availability of green spaces showed no effect on MVPA. Different moveability indices were constructed based on the walkability index accounting for the negative impact of land use mix. Moveability indices showed also strong effects on MVPA in school ...
