The transportation sector accounts for about a quarter of global greenhouse gas emissions. Previous research suggests that major life events may be “windows of opportunity” for travel behaviour change. Our scoping review examined the effects of seven events (transitions to secondary school, post-secondary studies, labour market, marriage, parenthood, retirement, and relocation) on travel behaviours. Five databases were searched (MEDLINE, APA PsycINFO, Web of Science, SportDISCUS, and ProQuest Dissertations and Theses) and 80 articles met inclusion criteria. Relocation was the most commonly examined event (with 51 studies). Findings illustrate that moving to compact neighbourhoods (with shorter commute distance/travel time, greater walkability/access to destinations) was associated with shifts towards sustainable travel modes (e.g., walking, cycling, and transit). Relocation might be particularly conducive to implementing scalable sustainable transportation interventions, as all six interventions with appropriate statistical power were effective. Entry into the labour market was generally associated with increased car use and declines in sustainable transportation. Qualitative studies suggested that attitudes towards cycling may become negative during adolescence, while attitudes towards driving improve, highlighting a need for concerted action. Evidence for other events was less consistent. Research in developing countries remain scarce and further intervention research is needed to enhance quality of evidence.

Background: Previous research shows that children from ethnic minority groups spend less time outdoors. Using data collected in 3 regions of Canada, we investigated the correlates of outdoor time among schoolchildren who spoke a nonofficial language at home. Methods: A total of 1699 children were recruited from 37 schools stratified by area-level socioeconomic status and type of urbanization. Among these, 478 spoke a nonofficial language at home. Children’s outdoor time and data on potential correlates were collected via questionnaires. Gender-stratified linear multiple regression models examined the correlates of outdoor time while controlling for age and sampling variables. Results: In boys, higher independent mobility, higher outdoor air temperature, mobile phone ownership, having older parents, and parents who biked to work were associated with more outdoor time. Boys living in suburban (vs urban) areas spent less time outdoors. The association between independent mobility and outdoor time became weaker with increasing age for boys. In girls, lower parental education and greater parental concerns about neighborhood safety and social cohesion were associated with less outdoor time. Conclusions: Correlates of outdoor time differ by gender and span the social ecological model underscoring the need for gender-sensitized interventions targeted at individual, family, social, and physical environmental correlates to increase outdoor time.
