A research review identified in this week's news/reports describes how cooperation between governments, municipalities and school boards is required if schools are going to be able to get beyond projects and "passive" responses to this intervention that has the most impact on daily physical actiivity among students. Without this type of cooperation, it is unlikely that exhortations to parents to forget about those challenges (and sometimes legal charges) and let their children freely walk to school. This evidence review was done for the education ministry of Ontario, Canada. It assessed the impact of adopting active school transportation policies within governments, municipalities and school boards. "The searches of health, education and sports databases identified 608 abstracts. Governments have increased their focus on increasing both active travel to school and physical activity. Many US states have policies. that may impact active travel in school in addition to the Safe Routes to School SRTS program. Six categories of state statutory (legislative) and administrative (regulatory) laws were examined (minimum busing distance, hazardous route exemptions to the distance requirement (hazards, traffic or unsafe crossing), sidewalk requirements near schools, crossing guards, traffic control measures (e.g., speed bumps) and speed zones around schools." All of these measures had some effect. "The odds of having walking school bus (WSB) program is significantly associated with district policies and a state law requiring crossing guards. However, none of the other state law variables were strongly associated with a WSB program. There is limited literature that assesses the impact of municipalities adopting active transportation policies, which is often associated with millions of funding invested. Further research is needed." Read more >> (An item from the ISHN Member information service)

(From the ISHN Member information service) Using odds ratio calculations from data from the Canadian HBSC survey, a researcher shows (Vol 66, 2014, Preventive Medicine) that both the perception of safety in a neighbourhood, as well as the actual crime rate, will affect the levels of physical activity among adolescents. However, the article suggests that these are independent variables (with actual crime rates having more impact than perceived safety). Consequently, the author suggests that the reach of PA programs can be improved if we address the perceptions of safety alone. "After controlling for crime and relevant confounders, the relative odds of being physically active outside of school was 0.52 (95% CI: 0.44–0.62) in youth whose perceptions of neighborhood safety were in the lowest quintile. After controlling for perceptions of safety and relevant confounders, the relative odds of being physically active outside of school was 0.75 (0.60–0.95) in youth from neighborhoods with crimes against persons scores in the highest quintile. Within this large sample of 11–15 year olds, perceptions and objective measures of neighborhood safety and crime were independently associated with physical activity in free-time outside of school.

(An item from the ISHN Member information service) A systematic review published in Volume 24, 2013 of Health & Place describes the various theories that explain how the social and physical environment of the school impacts student health. A composite model has been developed by the reviewers. The authors note that "We included 37 reports drawing on 24 theories. Narrative synthesis summarised and categorised theories. We then produced an integrated theory of school environment influences on student health. This integrated theory could inform complex interventions such as health promoting schools programmes. Using systematic reviews to develop theories of change might be useful for other types of ‘complex’ public-health interventions addressing risks at the individual and community levels." Their "Integrated theory of school environment explains influences on students. A figure illustrates the integrated theoretical model of the ways in which the ‘school environment’, at the top of the figure, influences at multiple inter-acting levels: (1) student–school commitment; (2) students–peer commitment; (3) student cognitions; and (4) students’ behaviours. Key theoretical concepts addressing upstream, medial and proximal pathways are identified in italics. The ‘feedback’ loops in the diagram illustrate how both the school environment influences health, but also the enactment of health behaviours influences the school environment and each preceding pathway."
