Children’s independent mobility (CIM), or a child’s freedom to explore their neighbourhood unsupervised, is important for their psychological development and potentially enables daily physical activity. However, the correlates of CIM remain under-studied particularly in terms of the influence of the neighbourhood environment. Within this context, children’s independent mobility in Toronto, Canada, was examined using linear regression and ordered logit models. Findings demonstrate that a higher level of CIM was correlated with more physical activity. Parental perceptions related to neighbourhood safety, stranger danger and sociability were associated with CIM. A child’s independent mobility was also correlated with age, sex, language spoken at home and parental travel attitudes. Interventions to increase CIM should focus on enhancing the neighbourhood social environment. Increasing the independent mobility of girls and of children with diverse ethno-cultural backgrounds are also worthy of particular research and policy attention. [ABSTRACT FROM PUBLISHER]

This paper describes a revised measure of self-efficacy to overcome barriers to moderate and vigorous physical activity in a sample of 484 high school students in Toronto, Ontario. The students had a mean age of 15.3 years. Principal axis factoring with oblique rotation yielded five factors: self-efficacy to overcome internal, harassment, physical environment, social mvironment, and responsibilities barriers. Two problematic items were removed, which resulted in a 22-item measure. Subsequent analyses were conducted on responses to this shortened measure. Confirmatory factor analysis supported the five-factor model and demonstrated age- and sexinvariance. The subscales had good internal consistency reliability. Structural regressions demonstrated a strong relationship between the resulting factors and a physical activity measure (energy expenditure), showing predictive validity. [ABSTRACT FROM AUTHOR]

Abstract: Environmental measures that are designed to facilitate changes in opportunities for active school transport (AST) do not often account for individuals’ interpretations of the built environment (BE) in different urban contexts. The Built Environment and Active School Transport (BEAT) project was undertaken to explore the ways in which the transport-BE interface gives rise to the use of active or non-active travel modes as the primary travel mode for school trips. We wanted to know how children experienced and understood the transport-built environment relationship. We selected four Toronto elementary school sites in areas that differed with respect to socio-economic status and built environment. We conducted photovoice interviews with 41 children, 21 who walked to/from school, and 20 who were driven. Adopting a thematic analytic approach, this paper examines the similarities and differences in the visual narratives of children’s transport geographies and discusses some of the benefits of using photovoice with children in a study of the transport-built environment relationship.

Abstract: Interest in utilitarian sources of physical activity, such as walking to school, has emerged in response to the increased prevalence of sedentary behavior in children and youth. Public health practitioners and urban planners need to be able to survey and monitor walking practices in space and time, with a view to developing appropriate interventions. This study explored the prevalence of walking to and from school of 11–13 year olds in the Greater Toronto Area (GTA), Canada. The Getis–Ord (G i *) local spatial statistic, Markov transition matrices, and logistic regressions were used to examine the spatial clustering of walking trips in the study area, and to document any temporal drift of places in and out of walking clusters. Findings demonstrate that walking tends to cluster within the urban and inner-suburban GTA, and in areas with low household income. Temporally persistent cluster membership was less likely within inner-suburban and outer-suburban places. The evidence suggests that interventions to increase active school transportation need to acknowledge spatial and temporal differences in walking behavior. [Copyright &y& Elsevier]
