Background: The objective of this study was to investigate the relationship between engagement in multiple risk behaviours (MRB) and concussion amongst youth. Methods: This was a cross-sectional study that used survey data collected from 3059 students in grades 6-10 (approximate ages 11-15 years) from Ontario, Canada. Students reported whether or not they had a medically diagnosed concussion within the previous 12 months and the frequency that they participated in several risky behaviours includ...

Declines in exposure to nature may deprive young people of experiences that are positive for their mental health. One factor that may interfere with connections to nature is use of electronic screen technologies. The objectives of this study are to (1) document variations in the perceived importance of connections to nature nationally among adolescents; (2) explore relationships between these connections and the use of electronic screens, both epidemiologically and qualitatively; and (3) integra...

BACKGROUND: Physical fitness during childhood is an important indicator of current and future health. This paper provides an overview of the fitness of Canadian children and youth aged 6 to 19 years. DATA AND METHODS: Data are from three cycles of the Canadian Health Measures Survey (CHMS) spanning a 10-year period: 2007 to 2009 (n = 2,081), 2009 to 2011 (n = 2,133) and 2016 to 2017 (n = 2,070). The CHMS is a comprehensive direct health measures survey conducted on a nationally representative sa...

Children’s independent mobility (IM), their freedom to move about their neighbourhood without supervision by adults, has been in steady decline in recent decades. Previous research has linked perceptions of the environment with various measures of IM, but recently concerns have been raised regarding inconsistency in measuring IM. This study used various measures of IM and aimed to address how parental perceptions of the neighbourhood environment are associated with children’s territorial range (...

BACKGROUND: Surveillance of physical activity among Canadian adults has typically relied on questionnaire-based data, which have many limitations. The Canadian Health Measures Survey (CHMS) has been collecting objective, accelerometer-based physical activity data on a nationally representative sample of Canadian adults since 2007. DATA AND METHODS: Data are from Cycle 1 (2007 to 2009), Cycle 2 (2009 to 2011), Cycle 3 (2012 to 2013), Cycle 4 (2014 to 2015) and Cycle 5 (2016 to 2017) of the CHMS. ...

Abstract Purpose The purpose of this study was to determine which intensities, patterns, and types of 24-h movement behaviors are most strongly associated with cardiometabolic risk factors among children. Methods A total of 369 children aged 10–13 years were studied. Participants wore an Actical accelerometer and a Garmin Forerunner 220 GPS logger and completed an activity and sleep log for 7 days. Data from these instruments were combined to estimate average minutes/day spent in 14 intensities,...

Open streets programs are free and multisectoral programs in which streets are temporally closed allowing access to walkers, runners, rollerbladers, and cyclists. The Move on Bikes program (by its name in Spanish Muevete en Bici) (MEB) consists of 55 km of interconnected streets in middle-high income areas of Mexico City. There is scarce evidence on the evaluation of this program in Mexico. The purposes of this study were to estimate the participation, physical activity levels among the MEB part...

Objectives To use a predominately objective measurement approach to assess and describe: (1) the amount of time that children aged 10–13 years spend participating in outdoor active play, active travel, curriculum-based physical activity at school, and organized sport; (2) the movement intensity composition of these four types of physical activity (i.e., % of time spent at a sedentary, light, or moderate-to-vigorous intensity); and (3) the proportion of each movement intensity obtained by partici...
