Hide Abstract
Lower levels of physical activity are associated with childhood obesity. School physical education (PE) policies have been identified as critical to improve child and adolescent physical activity levels but there has been little evaluation of such policies. In the province of Manitoba, Canada, the government implemented a mandatory PE policy in secondary schools designed to increase the daily physical activity levels of adolescents. The objective of this study was to examine the longitudinal changes in and the factors associated with the physical activity trajectories of adolescents in Manitoba during their tenure as secondary school students in the context of this school PE policy. The results found, despite the PE policy, a grade-related decline in the physical activity trajectories of adolescents; however, the decline in physical activity was attenuated among adolescents with low and moderate baseline physical activity compared to adolescents with high baseline physical activity and among adolescents who attended schools in neighbourhoods of low compared to high socioeconomic status. There are several possible explanations for these findings, including the influence of the PE policy on the PA patterns of adolescent subpopulations that tend to be at higher risk for inactivity in both childhood and adult life.

Patterns of weekday and weekend physical activity in youth in 2 Canadian provinces.

Hide Abstract
Few Canadian children are meeting physical activity (PA) guidelines for optimal growth and health. There is little information describing the patterns of PA among Canadian youth, so it is difficult to determine where the deficits occur. The purpose of this study was to identify subgroups of youth and windows of time characterized by low PA and high sedentary behaviour. We conducted a cross-sectional study of 626 youth (aged 10-15 years) in 2 Canadian provinces. The primary exposure variables included geographic setting (rural vs. urban), sex, and days of the week (weekend days vs. weekdays). The primary outcome measures were minutes of light PA, moderate to vigorous physical activity (MVPA), and sedentary behavior, assessed with accelerometry. Compared with weekdays, MVPA was ?30% lower on weekend days (55.8 ± 23.0 min vs. 38.7 ± 26.7 min; p < 0.001), whereas light PA was ?15% higher. Significantly more youth achieved an average of >60 min of MVPA on weekdays than on weekend days (46% vs. 22%; p < 0.001). Sex-specific differences in MVPA were more pronounced on weekdays than on weekend days (?13 vs ?8 min per day; p < 0.01). Youth in rural settings achieved ?9 fewer minutes of MVPA daily than youth in urban settings (p < 0.001). In youth 10 to 15 years of age, daily MVPA is lower and light PA is higher on weekend days than on weekdays. Girls and students living in rural areas were particularly vulnerable to low levels of MVPA.

The Battle River Project: school division implementation of the health-promoting schools approach: assessment for learning: using student health and school capacity measures to inform action and direct policy in a local school district.

Hide Abstract
The Battle River Project (BRP) is a school division-level intervention in rural Alberta, Canada, built upon the health-promoting schools approach to health promotion. Using self-reported school and student-level data from administrators and students, the central aim of the BRP is to examine: How can the school environment and health behaviours (healthy eating, physical activity and mental wellness) of children and youth be improved when a health-promoting schools model, the Ever Active Schools program, is implemented with school division support? Evidence used to inform school level changes included students demographic, behavioral, and psychosocial variables linked to school environment data, comprised of school demographics and administrator-assessed quality of policies, facilities, and programs related to physical activity. Each participating school and the division were provided with a tailored report of their schools results to reflect, plan and implement for positive health behavior change. The main lesson learned was that sharing school-specific evidence can operate as a catalyst for embedding health promoting policy and practices within the school and division culture.

A multilevel examination of school and student characteristics associated with physical education class enrollment among high school students.

Hide Abstract
Schools can be an efficient venue for promoting physical activity (PA) among adolescents. Physical education (PE) requires investigation because it is a variable associated with adolescent PA levels and its existence in schools represents a significant opportunity for strategies to combat declining PA levels among this population. This article examines the between-school variability in student rates of PE enrollment among a large sample of high schools in Ontario, Canada, and identifies the school- and student-level characteristics associated with PE enrollment.

Hide Abstract
Schools represent an important environment for physical activity (PA) promotion among youth. Schools can promote PA through policies and programs but our understanding of how these school characteristics associate with student PA levels is largely unknown. Developing this understanding is critical for implementing new prevention interventions. The aim of this study was to identify the school- and student-related characteristics associated with moderate and high levels of PA in a sample of Ontario elementary schools.

The Happy Meal® Effect: the impact of toy premiums on healthy eating among children in Ontario, Canada.
Can J Public Health
Show Abstract
Hide Abstract
"Toy premiums", offered with McDonalds Happy Meals®, are a prominent form of food marketing directed at children. Two California jurisdictions recently implemented policies that only permit offering fast-food toy premiums with meals that meet certain nutritional criteria. The primary objective of the current study was to examine elements of this policy in a Canadian context and determine if children select healthier food products if toy premiums are only offered with healthier food options. The study also examined if the impact of restricting toy premiums to healthier foods varied by gender and age.

A multilevel examination of gender differences in the association between features of the school environment and physical activity among a sample of grades 9 to 12 students in Ontario, Canada.
BMC Public Health
Show Abstract
Hide Abstract
Creating school environments that support student physical activity (PA) is a key recommendation of policy-makers to increase youth PA. Given males are more active than females at all ages, it has been suggested that investigating gender differences in the features of the environment that associate with PA may help to inform gender-focused PA interventions and reduce the gender disparity in PA. The purpose of this cross-sectional study was to explore gender differences in the association between factors of the school environment and students time spent in PA.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
