Development and statistical discussion of an index to assess the opportunities for physical activity in the neighborhood environment of children
- The aim of this study was to assess characteristics of the built environment in European regions of the IDEFICS study (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) and to adapt and expand the walkability concept with regard to physical activity levels in children. The walkability concept is used to assess characteristics of the urban environment that enable walking and that focus on physical activity levels in adults and is mainly implemented in study regions in the U.S. or Australia. Different geostatistical methods were investigated within one German region of the IDEFICS study to quantitatively and qualitatively assess urban characteristics and to calculate urban measures with regard to physical activity levels of 2- to 9-year old children that participated in the IDEFICS study.
Based on the walkability concept we assessed urban characteristics that describe opportunities for walking provided by short routes, diverse destinations in the neighborhood and the availability of public transit. To expand the walkability concept with regard to children, which are mainly physically active during leisure time, we particularly considered public open spaces and recreational facilities and assessed the availability of these characteristics based on a kernel density approach using their mid-point.
Especially parks and playgrounds showed a positive effect on moderate to vigorous physical activity (MVPA) of children compared to other recreational facilities. Thus, we assume that the spatial availability of designed public open spaces contributes to moveable neighborhoods, which is also supported considering qualitative aspects of recreational facilities. Investigating urban measures, such as residential density, land use mix, and street connectivity, with regard to MVPA of children from the German study region, Delmenhorst, revealed a negative effect of land use mix and only positively small effects of residential density and street connectivity resulting in a moveability index to quantify opportunities for phyiscal acitivty in children.
Hence, with regard to children, mainly residential districts with good access to design public open spaces seem to provide sufficient opportunities for physical activity. However, perceived safety concerns negatively influence physical activity levels of children and should be considered as important confounders, beside socio-economic status of the parents, such as education and household income.
We particularly considered adaptive bandwidths that are able to capture the environmental variability and the topography of the urban environment. Our results showed that distances of 1.000m and 1.250m may capture the spatial context of children and modelling a two-dimensional bandwidth adjusted for residential density can improve the calculation of the spatial availability.
Implementing the moveability index in large urban areas will allow to quantify districts with respect to their supportiveness for physical activity and hence to give recommendations for urban planners and stakeholders.
