Perceived neighbourhood safety moderates the relationship between active school travel and health-related quality of life.

There is a dearth of studies examining associations between active school travel and children's health-related quality of life. Additionally, studies have not examined how perceived neighbourhood characteristics may moderate these associations. This study aims to examine the relationship between regular active school travel, children's physical and psychosocial health-related quality of life, and the potential moderating effects of their perceived neighbourhood safety (interpersonal and traffic). This cross-sectional study used data from Ontario schoolchildren (aged 8-14) as part of the Spatial Temporal Environment and Activity Monitoring (STEAM) Project. Results showed no significant direct relationship between regular active school travel and children's physical or psychosocial functioning; but the relationships were moderated by perceived neighbourhood safety. Regular active school travelers with high levels of perceived neighbourhood interpersonal safety, had higher physical and psychosocial functioning than regular active school travelers with low levels of perceived neighbourhood interpersonal safety. Additionally, at higher levels of perceived neighbourhood traffic safety, regular active school travelers had higher psychosocial functioning than regular active school travelers with lower perceived neighbourhood traffic safety. Interventions promoting active school travel should consider the environments through which children will be traveling.

Examining how changes in provincial policy on vape marketing impacted the distribution of vaping advertisements near secondary schools in London, Ontario.

OBJECTIVES: On January 1, 2020, the Government of Ontario passed a regulation banning vaping advertisements by retailers, apart from specialty shops. A motivation for this ban was to limit youth exposure to vaping advertisements. The primary goal of this research was to evaluate the impact of this ban on the number and density of vaping advertisements surrounding secondary schools. Additionally, we examined whether the number of vaping advertisements varied by school socio-demographic characteristics. METHODS: This study used a pre-post design. Audits were conducted December 2019 (pre-ban) and again January to February 2020 (post-ban), to identify vaping advertisements within 800 m surrounding secondary schools (n = 18) in London, Ontario. RESULTS: Prior to the ban, there were 266 vaping advertisements within 800 m of secondary schools. After the ban, this was reduced to 58, a 78.2% reduction. The mean number of vaping advertisements surrounding schools significantly decreased from 18.1 before the ban to 3.6 after the ban (p < 0.001). A significant positive correlation was found, prior to the ban, between the number of vaping advertisements surrounding schools and school-level residential instability (r = 0.42, p = 0.02). After the ban, no significant correlations were found between the number of vaping advertisements and school socio-demographic characteristics. CONCLUSION: The provincial ban of vaping advertisements in select retail settings significantly reduced the number of vaping advertisements in the areas surrounding secondary schools in London, Ontario. The ban also reduced socio-demographic inequities in youths' potential exposure to marketing of vaping products. Continued monitoring of the geographic accessibility and promotion of vaping products is warranted.

RéSUMé: OBJECTIFS: Le 1er janvier 2020, le gouvernement de l'Ontario adoptait un règlement interdisant les annonces publicitaires sur le vapotage dans les magasins de détail, sauf dans les boutiques spécialisées. L'une des raisons de cette interdiction était de limiter l'exposition des jeunes à la publicité sur le vapotage. Notre étude visait principalement à évaluer les incidences de l'interdiction sur le nombre et la densité des annonces publicitaires sur le vapotage autour des écoles secondaires. Nous avons aussi cherché à déterminer si le nombre d'annonces publicitaires sur le vapotage variait selon le profil sociodémographique des écoles. MéTHODE: Un protocole avant-après été utilisé pour cette étude. Des audits ont été menés en décembre 2019 (avant l'interdiction), puis de nouveau en janvier et février 2020 (après l'interdiction) pour dénombrer les annonces publicitaires sur le vapotage dans un rayon de 800 m des écoles secondaires (n = 18) de London, en Ontario. RéSULTATS: Avant l'interdiction, il y avait 266 annonces publicitaires sur le vapotage dans un rayon de 800 m des écoles secondaires. Après l'interdiction, ce nombre n'était plus que de 58, soit une baisse de 78,2 %. Le nombre moyen d'annonces publicitaires sur le vapotage autour des écoles a diminué de façon significative, passant de 18,1 avant l'interdiction à 3,6 après (p < 0,001). Une corrélation positive significative a été observée, avant l'interdiction, entre le nombre d'annonces publicitaires sur le vapotage autour des écoles et l'instabilité résidentielle au niveau des écoles (r = 0,42, p = 0,02). Après l'interdiction, aucune corrélation significative n'a été observée entre le nombre d'annonces publicitaires sur le vapotage et le profil sociodémographique des écoles. CONCLUSIONS: L'interdiction provinciale des annonces publicitaires sur le vapotage dans certains magasins de détail a considérablement réduit le nombre de ces annonces dans les environs des écoles secondaires de London, en Ontario. L'interdiction a aussi réduit les iniquités sociodémographiques de l'exposition potentielle des jeunes au marketing des produits de vapotage. Il est justifié d'assurer une surveillance continue de l'accessibilité géographique et de la promotion des produits de vapotage.

Measuring Temporal Differences in Rural Canadian Children's Moderate-to-Vigorous Physical Activity.

The purpose of this study was to measure the factors that influence children's moderate-to-vigorous physical activity (MVPA) during school curriculum time, recess time, and outside school time in a rural area. During the Fall and Winter of 2016, 34 boys and 55 girls aged 8-14 years from rural communities in rural Northwestern Ontario participated in the Spatial Temporal Environment and Activity Monitoring project. The children's MVPA was measured using an accelerometer, and child-level demographic, behavioral, and environmental data were gathered from surveys, passively logging global positioning units, and municipal datasets. Data on daily temperature and precipitation were gathered from the closest Environment Canada weather station. A mixed model was used to assess the relationship between child- and day-level factors and children's MVPA. On average, children were getting 12.9 min of MVPA during recess, 17.7 min during curriculum time, and 29.0 min of MVPA outside school time. During all three time points, boys were more active than girls. During curriculum time, children in lower grades were more active, and the weather had differing impacts depending on the time of day. The findings of this study illustrate the differences in MVPA and the factors that influence MVPA by time of day. Examining different time segments provides valuable information for understanding children's MVPA patterns.

Examining Factors of Accelerometer-Measured Sedentary Time in a Sample of Rural Canadian Children.

The aim of this study was to examine potential child-level and day-level factors of accelerometer-measured sedentary time in a sample of rural Canadian children. Children (n = 86) from rural Northwestern Ontario participated in this study. Children's sedentary times were identified and logged using an accelerometer. Child-level data (socio-demographic, household, and environment) came from surveys of children and their parents and a passively logging global positioning unit. Day-level data on day type (weekday/weekend) and weather (temperature, precipitation) were based on the dates of data collection and meteorological data came from the closest Environment Canada weather station. Cross-classified regression models were used to assess the relationship between child-level and day-level correlates of sedentary time. Boys were less sedentary than girls (b = -30.53 p = 0.01). For each one-year age increase, children's sedentary time increased (b = 12.79 p < 0.01). This study indicates a difference in sedentary time based on a child's age and gender. However, family, environmental, and weather characteristics did not influence sedentary time in this sample. Health practitioners who deliver care for northern rural youth can provide targeted health advice regarding sedentary time and consider gender and age to be risk factors for these behaviors.
