This study takes a child-centred approach to examine the relationship between children's third-place play, parents' perceptions of their neighbourhood environment, and time spent by children in physical activity and sedentary behaviour during weekday out-of-school hours. A total of 1102 children aged 8–13 years from 19 schools across Auckland, New Zealand took part in a public participation geographic information systems (PPGIS) survey utilising closed- and open-ended questions and child mapping of destinations. The results suggested that playing in green places near home were associated with more time spent in light physical activity and less sedentary behaviour. Children who played in street places near home (e.g. driveways, footpath, carpark) spent more time in moderate to vigorous physical activity. Although parental perceptions of their neighbourhood environment were not directly associated with children's time spent in physical activity, children with parents who perceived their neighbourhood as more connected were more likely to engage in third-place play.

The advertising of unhealthy food and beverages forms an important component of obesogenic environments. Such marketing to children is a key health determinant because of its impact on dietary preference and food purchasing behaviour. The location of outdoor advertising is important in exploring obesogenic environments and children's neighbourhoods. The aim of this study is to explore issues involved in the use of Google Street View to examine outdoor food and beverage advertising. The implications for using Google Street View in the context of neighbourhood built environment research and grass‐roots advocacy are discussed. The study was conducted within walkable distances from 19 primary and intermediate schools in Auckland, New Zealand, where "walkable" was defined as limited by 800 m road network boundaries, which are equivalent to school buffer boundaries. Google Street View allows for centrality of data collection, coding, and storage. However, challenges exist with the method because 727 (29.4%) of a total of 2,474 outdoor advertisements that were identified were not able to be categorised because images were unclear, not in English, blocked, or at angles where detail cannot be deciphered. Specific to outdoor advertising for food and beverages, the results presented here show that children are exposed to a significantly greater number of unhealthy advertising than other advertising, P=0.001, eta‐squared statistic (0.45) indicates a large effect size. Overall, the results show promise for the use of Google Street View in the study of obesogenic environments. [ABSTRACT FROM AUTHOR]

Highlights • Use of online participatory mapping to measure children's travel routes to school. • About 50% of the child-drawn routes were spatially matched with GIS shortest routes. • The built environment differed between child-drawn routes and GIS shortest routes. • Active travel routes in pedestrian network were more similar to child-drawn routes.
