Book Description
Background: Most Canadians are inactive. Given insufficient physical activity is linked to multiple chronic diseases and mortality, increasing physical activity has become a public health priority. To inform future interventions, modifiable correlates and determinants of physical activity need to be identified. Local, national, and international policy documents have highlighted the importance of creating active living environments that promote regular physical activity. While several behvioural settings exist, neighbourhoods provide opportunities for both structured and unstructured physical activity opportunities for multiple ages. However, before modifying existing environments or developing new active living environments, it is first important to consider the features that promote physical activity. Further, for active living environments to have a sustainable impact, identifying features that promote physical activity across multiple ages groups is important. Therefore, the overall purpose of this dissertation is to identify environmental correlates of physical activity across multiple age groups (preschool children, school-aged children, adolescents, adults) within the neighbourhood setting. Methods: Three studies were conducted. In study one, parents were surveyed regarding the features of their neighbourhood environment that they perceived as important to their own physical activity as well as their children's physical activity and parent-child coactivity. In study two, associations of objectively measured walkability and parental perceptions of the environment with children's physical activity (i.e., daily step counts, parent reported physical activity) were examined using data from the SHAPES of Things to Come project. In study three, the longitudinal associations between the objectively measured built environment surrounding schools and self-reported physical activity and active mode of transport among adolescents were examined using data from the COMPASS project. Results: In study 1, several neighbourhood features, related to destinations, design, social, safety and aesthetics, were identified by the majority of parents as important for their own physical activity, their child's active play, and parent-child coactivity. There were several significant differences in the proportions of parents who identified features as relevant between activity types (parent physical activity, child active play, parent-child coactivity). Few differences were observed by household income. In study two, objectively measured walkability was not associated with children's steps or parent reported physical activity. However, significant associations were observed for neighbourhood aesthetics and traffic hazards with parental reported physical activity, along with walking and cycling infrastructure during the winter months. In study 3, significant associations were observed between retail-, park-, and recreation center- densities along with Walk Scores in the school neighbourhood environment with adolescent MVPA and active school travel. Students attending schools in environments considered very walkable had an increased likelihood of active school travel and maintained higher MVPA over time. Conclusion: Across all three studies, there is evidence to suggest features that support walking is important for preschool children's active play, parents' recreational physical activity and coactivity with their children, along with school-aged children's parent reported physical activity, and adolescent's self-reported active school travel and MVPA. Finding ways to incorporate features that support walking into home and school neighbourhoods could promote physical activity across age groups. More longitudinal research that accounts for behavioural and context-specificity, multiple activity settings and their characteristics, and intra- and inter- personal characteristics is needed.

Book Description
Background: Ecological models posit that interactions among factors at multiple levels (e.g., individual, psychosocial, and environmental) influence physical activity (PA). However, interactions involving environmental factors are the least understood. Intervention studies also suggest PA behavior change may depend on the environments in which participants are encouraged to be active but such evidence from interventions targeting Latinos is limited. Methods: Chapter 2 tested interactions between neighborhood environmental and socio-demographic factors on total moderate-to vigorous physical activity (MVPA) among an international adult sample (N=10,258). Chapter 3 examined interactions between neighborhood environmental and psychosocial factors on context-specific PA among an adolescent sample from the Baltimore/Seattle regions (N=910). Chapter 4 assessed the moderating effects of neighborhood environmental factors on the impacts of a physical activity intervention targeting Latinas in San Diego, CA at 12-months post-intervention (N=319). Results: Chapter 2 found moderating effects by education and gender on the association between safety from crime and meeting high PA levels, with inverse associations found only among the high-education group and men. Education and gender moderated associations of safety from crime and the presence of transit stops with meeting minimum PA guidelines, with positive associations found for safety from crime only among women and the presence of transit stops only among men and the high-education group. Chapter 3 found moderating effects by decisional balance on the association between recreation facility density and neighborhood leisure-time PA among female adolescents, with a negative association found only among those with high decisional balance. Decisional balance also moderated the associations of neighborhood walkability with non-school MVPA among females and non-neighborhood leisure-time PA among males, with positive associations only among adolescents with high decisional balance. Chapter 4 showed higher total MVPA and leisure-time MVPA at 12-months post-intervention among participants with favorable perceived neighborhood aesthetics than those with less favorable evaluations. Conclusions: This dissertation supports the ecological models' hypothesized interactions between environmental and individual/psychosocial factors on PA and the moderating role of the neighborhood environment on the impacts of a multilevel PA intervention targeting Latinas. Findings support global efforts targeting multiple levels of influence to promote population PA, health, and environmental sustainability.

Book Description
Environmental correlates of physical activity behaviour have received much attention in the public health, geography, urban design, planning and transport literature over the past decade. Adolescents are an important age group to consider, given habits developed in childhood can potentially track into adulthood. This is an age where young people begin to have independent mobility, which has been associated with increased physical activity levels. The built environment is consistently associated with physical activity behaviours among adolescents. However, gaps in knowledge exist around which environmental features influence adolescent physical activity. Moreover, very little research has been undertaken on adolescents living in regional or rural areas.To date, proximity to parks (often measured as the closest park to a study participant's residence) and availability of facilities have often been examined as correlates of physical activity participation. Park attributes, that make parks more desirable to adults, have been identified and an attractiveness score has been developed in accordance with adult park use. Yet, there appears to be no published research that has identified which attributes of a park (in isolation or combination) make a park more appealing for adolescents to use for physical activity. Moreover, rarely has a study looked at the attributes of parks that have actually been reported as being used by study participants.Methods used to audit parks have traditionally relied on site visits to subjectively measure park attributes. This method of park auditing can be costly and time consuming. As such, a more objective method that eliminates the need for site visits could potentially advance research methods associated with the built environment and physical activity participation. Indeed, the use of geographic information systems (GIS) enables remote-assessment methods and the opportunity to measure park attributes in a more objective fashion.The overarching aims of this research were to investigate the environmental factors related to adolescent 'park and beach use' and physical activity and in doing so, develop environmental measures relevant to adolescent physical activity.

Book Description
Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.

Book Description
"The purpose of this study was to develop a better understanding of the physical activity behavior of Black female adolescents age 14-18 in the Charlotte, NC public school community by examining the relationship between physical activity and self-efficacy, social support, outcome expectations, and physical environment. The study sample consisted of 96 girls ages 14-19 from a public high school in Charlotte, North Carolina. Participants volunteered to complete a survey with demographic, physical activity (PA), and psychosocial questions. The predictor variables were self-efficacy and physical activity self-efficacy, social support, outcome expectations, and physical environment. The dependent variable was physical activity participation. Correlational analysis was employed to examine the relationship of the four predictor variables to physical activity. Self-efficacy was shown to be correlated with PA. The strongest correlation was between physical activity self-efficacy and PA. Correlations between outcome expectations and PA for the total sample were low and not significant. Total social support, family and friend social support were correlated with PA as well. Physical environment was not significantly related with PA for the Black adolescents in this study. Multiple regression was used to determine the relative strength of the four main predictor variables on the dependent variable of physical activity level. For the total sample, the four predictor variables explained 24% of the variance in physical activity participation. Of these variables, physical activity self-efficacy makes the largest unique contribution (beta=.36) with a significance level of .002. In order to understand PA habits and perceptions among Black adolescent females, the last section of the survey included 14 open-ended questions. Most Black participants understand the health benefits of physical activity, but cited tiring and sweating factors as reasons why they do not participate in physical activity. Findings suggest increasing physical activity self-efficacy and providing social support, as well as allowing girls to have a choice in their physical activity and offering activities they consider fun, may lead to increased physical activity among Black adolescent girls."--Abstract from author supplied metadata.
