Background: Several recent global events may have impacted adolescent sleep and exacerbated pre-existing disparities by social positions (i.e., social roles, identity or sociodemographic factors, and/or group memberships that are associated with power and oppression due to the structures and processes in a given society at given time). Current understanding of sleep among adolescents is critical to inform interventions for a more equitable future, given the short and long-term consequences of inadequate sleep on health and well-being. This study aimed to provide contemporary evidence on sleep disparities by key social positions among adolescents in Canada., Methods: Cross-sectional analyses were conducted using self-reported data collected during 2020-2021 (the first full school year after the COVID-19 pandemic onset) from 52,138 students (mean [SD] age = 14.9 [1.5]) attending 133 Canadian secondary schools. Multiple regression models were used to test whether sleep quality (how well students slept during past week), duration (weekday, weekend, weighted daily average), and guideline adherence (8-10 h/day) differed by sex and gender, race and ethnicity, and socioeconomic status (SES)., Results: Females reported a mean [95% CI] difference of -1.7 [-3.7, 0.4] min/day less sleep on weekdays than males, but 7.1 [4.5, 9.6] min/day more sleep on weekends, resulting in no difference in average daily sleep between males and females. Females were less likely to report good quality sleep compared to males (AOR = 0.57 [0.54, 0.60]). SES followed a generally monotonic trend where higher scores were associated with more sleep on weekdays (Δ highest: lowest = -28.6 [-39.5, -17.6]) and weekends (Δ highest: lowest = -17.5 [-3.8, -31.2]) and greater likelihood of higher sleep quality (AOR highest: lowest = 3.04 [2.35, 3.92]). Relative to White adolescents, weekday and average daily sleep duration were lower among all other racial identities; mean differences ranged from ∼ 5-15 min/day, with Black students reporting the least sleep., Conclusions: Differences in sleep duration and quality were most profound among adolescents from the lowest and highest SES. Racial disparities were more evident on weekdays. Compensatory weekend sleep appears more pronounced in females than males. Addressing sleep inequities is critical, as a robust predictor of multiple health outcomes., (© 2024. The Author(s).)

The purpose of this study was to explore the adaptations that schools made to physical activity programs and facilities, and disparities by area urbanicity and income, during the first school year after the emergence of the COVID-19 pandemic. In a convenience sample of 132 secondary schools in Canada, school contacts responded to an annual survey in the 2020-2021 school year on changes to physical activity programs and facilities, and related staff training. Content analysis categorized open-ended text responses, and schools were compared based on area urbanicity and median income. Most schools canceled all interschool sports (88.9%) and intramurals (65.9%). New programs were added by 12.6% of schools, and about half (49%) of schools reported some continuing programs, most of which were sports programs, followed by facility and equipment access. Physical activity facilities were closed in 18.1% of schools, while 15.7% had new facilities added, and 11% temporarily converted facilities into learning spaces. Large/medium urban schools were at greater odds of having made any change to their facilities compared to schools in rural/small urban areas (odds ratio (95% confidence interval): 2.3 (1.1, 4.8)). The results demonstrate the considerable scale and nature of the restrictions in school provisions of physical activity opportunities during this period, as well as the resourcefulness of some schools in adding new programs and facilities.

Objective: To provide contemporary evidence of how dietary intake and eating behaviours vary by social positions among adolescents., Methods: We used survey data collected during the 2020-2021 school year from 52,138 students attending 133 secondary schools in Alberta, British Columbia, Ontario, and Quebec, Canada. Multiple regression models tested whether self-reported indicators of dietary intake and eating behaviours differed by gender, race/ethnicity, and socioeconomic status (SES)., Results: Females were more likely than males to skip breakfast, restrict eating, and consume fruit, vegetables, and fast food on more days. Gender-diverse/"prefer not to say" students were more likely to restrict eating than males and the least likely to consume breakfast and drink water daily, and fruits and vegetables regularly. Black and Latin American students were more likely to restrict eating and consume purchased snacks and fast food, and less likely to drink water daily than white and Asian adolescents. Daily breakfast consumption was most likely among Latin American students. Black students were the least likely to report eating breakfast daily and fruits and vegetables regularly. Lower SES was associated with lower odds of eating breakfast and drinking water daily and regular fruit and vegetable consumption, and higher odds of restrictive eating and purchased snack consumption. Fast food consumption had a u-shaped association with SES., Conclusion: Results emphasize gender, racial/ethnic, and socioeconomic inequities in the diets and eating behaviours of adolescents. There is a critical need to address the structural factors contributing to inequities and prevent the consequences of dietary disparities., (© 2024. The Author(s).)

Purpose: Children who are allowed greater independent mobility (IM) are more physically active. This study investigated associations between parents' current travel mode to work, their own IM and school travel mode as a child, and their child's IM., Methods: Children in grades 4 to 6 (n = 1699) were recruited from urban, suburban, and rural schools in Vancouver, Ottawa, and Trois-Rivières. Parents reported their current travel mode to work, IM, and school travel mode as a child. Children self-reported their IM using Hillman's 6 mobility licenses. Multiple imputation was performed to replace missing data. Gender-stratified generalized linear mixed models were adjusted for child age, parent gender, urbanization, and socioeconomic status., Results: The older a parent was allowed to travel alone as a child, the less IM their child had (boys: β = -0.09, 95% confidence interval [CI], -0.13 to -0.04; girls: β = -0.09, 95% CI, -0.13 to -0.06). Girls whose parents biked to work (β = 0.45, 95% CI, 0.06-0.83) or lived in Trois-Rivières versus other sites (β = 0.82, 95% CI, -0.43 to 1.21) had higher IM. IM increased with each year of age (boys: β = 0.46, CI, 0.34-0.58; girls: β = 0.38, 95% CI, 0.28-0.48)., Conclusion: Parents who experienced IM later may be more restrictive of their child's IM. This may help explain the intergenerational decline in children's IM.

Background: To assess whether changes in breakfast and water consumption during the first full school year after the emergence of the COVID-19 pandemic varied based on sex/gender, race/ethnicity, and socioeconomic status among Canadian adolescents., Methods: Prospective annual survey data collected pre- (October 2019-March 2020) and post-COVID-19 onset (November 2020-June 2021) the Cannabis, Obesity, Mental health, Physical activity, Alcohol, Smoking, and Sedentary behaviour (COMPASS) study. The sample consisted of 8,128 students; mean (SD) age = 14.2 (1.3) years from a convenience sample of 41 Canadian secondary schools. At both timepoints self-reported breakfast and water consumption were dichotomized as daily or not. Multivariable logistic generalized estimating equations with school clustering were used to estimate differences in maintenance/adoption of daily consumption post-COVID-19 based on demographic factors, while controlling for pre-COVID-19 behaviour., Results: Adjusted odds ratios (AOR) with 95% confidence intervals are reported. Females (AOR = 0.71 [0.63, 0.79]) and lower socioeconomic status individuals (AOR Lowest:Highest =0.41 [0.16, 1.00]) were less likely to maintain/adopt daily breakfast consumption than male and higher socioeconomic status peers in the 2020-2021 school year. Black identifying individuals were less likely than all other racial/ethnic identities to maintain/adopt plain water consumption every day of the week (AOR = 0.33 [0.15, 0.75], p < 0.001). No significant interaction effects were detected., Conclusions: Results support the hypothesis that changes in nutritional behaviours were not equal across demographic groups. Female, lower socioeconomic status, and Black adolescents reported greater declines in healthy nutritional behaviours. Public health interventions to improve adherence to daily breakfast and water consumption should target these segments of the population., Trial Registration: Not a trial., (© 2024. The Author(s).)

Purpose: Considerable debate centered on the impact of school closures and shifts to virtual learning on adolescent mental health during the COVID-19 pandemic. We evaluated whether mental health changes differed by school learning modes during the pandemic response among Canadian adolescents and whether associations varied by gender and perceived home life., Methods: We used prospective survey data from 7270 adolescents attending 41 Canadian secondary schools. Conditional change linear mixed effects models were used to examine learning mode (virtual optional, virtual mandated, in-person, and blended) as a predictor of change in mental health scores (depression [Centre for Epidemiologic Studies - Depression], anxiety [Generalized Anxiety Disorder-7], and psychosocial well-being [Flourishing scale]), adjusting for baseline mental health and covariates. Gender and home life happiness were tested as moderators. Least square means were calculated across interaction groups., Results: Students learning in a blended learning mode had greater anxiety increases relative to their peers in other learning modes. Females learning fully in-person and males learning virtually when optional reported less of an increase in depression scores relative to their gender counterparts in other learning modes. Learning virtually when optional was associated with greater declines in psychosocial well-being in students without happy home lives relative to other learning modes., Conclusion: Findings demonstrate the importance of considering gender and home environments as determinants of mental health over the pandemic response and when considering alternative learning modes. Further research is advised before implementing virtual and blended learning modes. Potential risks and benefits must be weighed in the context of a pandemic., (© 2023. The Author(s).)

The purpose of this study was to assess if sub-populations of adolescents in Canada (i.e., race/ethnicity, sex/gender, and socioeconomic status [SES]) experienced a larger change in physical activity and screen time between the 2019-2020 (pre-pandemic) and the 2020-2021 (mid-pandemic) school years. Longitudinally linked data from pre-pandemic and mid-pandemic school years of a prospective cohort study of secondary school students in Canada (n = 8209) were used for these analyses. Multivariable regression modelling tested the main effects of race/ethnicity, sex/gender, and SES on changes in moderate-to-vigorous physical activity (MVPA) and screen time duration as well as adherence to Canada's 24-h Movement Guidelines. Overall between groups difference were assessed using type II analysis of deviance tests. Interactions between variables of interest were subsequently tested with a series of regression models compared to the main effects model using likelihood-ratio test. Post-hoc comparisons found Male participants' MVPA time decreased less compared to their female counterparts (M [95% CI] = -16.3 [-13.5, -19.2] min/day), but also reported greater increases in screen time compared to females (23.7 [14.7, 32.8] min/day) during the same period. MVPA in White participants decreased less than Asian participants (-10.7 [-19.5, -1.9] min/day) with a similar non-significant pattern observed in Black and Latin participants. Adolescents in higher SES categories fared better on adherence to MVPA (highest vs. lowest OR = 1.41 [0.97, 2.06]) and screen time recommendations(highest vs. lowest AOR = 3.13 [0.91, 11.11]). Results support the hypothesis that existing inequitable sociodemographic differences in MVPA participation and screen time have worsened throughout the pandemic., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Purpose: The purpose of this study was to assess if adolescent sub-populations in Canada (i.e., based on race/ethnicity, sex/gender, socioeconomic status, and urbanicity groups) experienced a larger change in sleep duration and guideline adherence between 2019 and 2020 (pre-pandemic) and the 2020-2021 (mid-pandemic) school years., Methods: Longitudinally linked data from 2019 to 2020 (pre-pandemic) and 2020-2021 (mid-pandemic) of a prospective cohort study of secondary school students (M = 14.2, SD = 1.3 years, N  = 8209) in Canada were used for analyses. Regression modelling tested the main effects of race/ethnicity, sex/gender, socioeconomic status, and urbanicity on changes in sleep duration as well as adherence to Canada's 24-h Movement Guidelines for sleep (8-10 h/night). Interactions between identity variables (race/ethnicity or sex/gender) and other main effect variables were subsequently tested., Results: Females gained more sleep (4.5 [1.5, 7.5] min/day more) and increased guideline adherence (AOR = 1.16 [1.04, 1.30] than males on average. Asian race/ethnic identity was associated with less sleep gain than White identity -10.1 [-19.4, -0.8], but not guideline adherence. Individuals in large urban areas gained less sleep and adhered less to guidelines than individuals from any other level of urbanicity (-21.4 [-38.5, -4.2] to -15.5 [-30.7, -0.2] min/day). Higher individual SES scores were associated with greater sleep gain (linear trend: 11.16 [1.2-21.1]). The discrepancies in sleep gain and guideline adherence between males and females were significantly modified by race/ethnicity and urbanicity., Discussion: Increases in sleep duration may be one of the few benefits to adolescents during the COVID-19 pandemic but were not equally distributed across sub-populations. Efforts to promote better sleep adherence may need to account for sex/gender differences, especially in less urbanized areas and certain racial/ethnic groups., Competing Interests: None., (© 2023 The Authors.

Background: The impact of the COVID-19 pandemic and consequent public health restrictions on the mental health of adolescents is of global concern. The purpose of this study was to examine how Canadian adolescents coped during the early pandemic and whether different coping methods were associated with changes in mental health from before the pandemic to the early lockdown response., Methods: Using two-year linked survey data (2018-2020) from a prospective cohort of secondary school students (n = 3,577), linear regression models were used to examine whether changes in mental health (anxiety [Generalized Anxiety Disorder-7 scale], depression [Center for Epidemiologic Studies Depression 10-item scale Revised], emotion regulation [Difficulties in Emotion Regulation Scale], psychosocial well-being [Flourishing scale]) were related to each coping behaviour., Results: The most common reported coping behaviours included staying connected with friends online (78.8%), playing video games, watching TV/movies, and/or surfing the internet/social media (76.2%), studying or working on schoolwork (71.0%), and getting exercise (65.2%). The use of positive coping mechanisms during the early pandemic period (e.g., keeping a regular schedule, time with family, time with friends online) was associated with less adverse mental health changes from before to during the early lockdown; whereas, negative coping mechanisms (e.g., spending time alone, eating junk food) were consistently associated with more adverse mental health changes., Conclusion: This study demonstrates the importance of social support and connections with both friends and family, as well as keeping and maintaining a routine, over the pandemic. Interventions supporting positive relationships and engagement in these coping behaviours may be protective for adolescent mental health during disruptive events., (© 2023. The Author(s).)

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.

Background: The impact of COVID-19 on adolescent mental health is a global concern. Increased screen time and reduced physical activity due to the lockdown measures have been linked to detrimental mental health outcomes; however, the literature remains limited by cross-sectional and retrospective designs, and consideration of behaviours in isolation. Prospective evidence is necessary to examine whether moderate-to-vigorous physical activity (MVPA), sleep and screen time influenced changes in mental health., Method: Analyses used data from a prospective cohort study of secondary school students in Canada with baseline data from the 2018-2019 school year and linked follow-up data from online surveys completed during the initial COVID-19 outbreak (May-July 2020). Multilevel linear regression models were used to evaluate the within- and between-person isotemporal substitution effects of sleep, MVPA and screen time behaviours on depression, anxiety, subjective well-being, and trait emotional dysregulation., Results: Linked longitudinal data from 2645 students attending 44 schools were available. Between-person effects indicated that individuals who engaged in more MVPA and sleep while minimizing screen time had lower depression scores, less severe emotional dysregulation, and better subjective well-being. While controlling for between-person effects, within-person year-on-year change suggests those who increased screen time while decreasing either MVPA or sleep experienced mental health decline on all outcomes., Conclusion: MVPA and sleep were associated with youth mental health during the early COVID-19 lockdown. Increasing MVPA and sleep (or at least mitigating the increase of screen time) compared to the prior year was associated with better mental health during the early pandemic. A limitation to consider is that the screen time measure represents a combination of screen behaviours, and effects of replacing screen time may have varied if distinctions were made., (© 2022 Elsevier Ltd.

Introduction: Mental disorders affect 1 in 5 children having consequences for both the child and their family. Indeed, the siblings of these children are not insulated from these consequences and may experience elevated levels of psychological distress, placing them at increased risk for developing mental disorders. This protocol describes the methodology for a scoping review that will examine how mental disorders in children impact the mental health of their sibling(s). Further, we aim to examine the role of sex, gender, birth order, age of each child, and familial factors (e.g., parent mental illness, family structure), in sibling mental health. The proposed review will also identify resources that aim to support the needs of siblings of children with mental disorders. Taken together, this proposed review aims to take a fundamental step towards determining intervention targets to reduce the transmission of risk between siblings., Aim: The proposed scoping review aims to address the following questions: i) how do mental disorders (in children <18 years of age) impact the mental health of their sibling(s) (also <18 years of age)? ii) Can we identify resources designed to address the needs of siblings of children with mental disorders?, Methods: We will conduct the proposed scoping review in keeping with the six-stage Arksey and O'Malley Framework and the scoping review methodology provided by the Joanna Briggs Institute. In section i) we outline our research questions. In section ii) we describe our process for identifying studies that examine the mental health of siblings of a child with a mental disorder and studies that provide evidence on resources directed specifically at these siblings. We will search peer-review and grey literature published between 2011 and 2022 from OVID MEDLINE, OVID EMBASE, CINAHL Complete, Proquest Nursing and Allied Health, PsycINFO (via APA platform), Proquest Sociology Collection and Web of Science Core Collection and Proquest Theses and Dissertations. Section iii) describes our process for selecting relevant studies. In sections iv and v, we describe our methods for charting and summarizing relevant data. Finally, in section vi) we describe our integrative knowledge translation plan that aims to include knowledge users in interpretating and translating evidence gathered from the proposed review., Competing Interests: The authors have declared that no competing interests exist.

Background: Comprehensive, prospective, longitudinal data are lacking on the effects of the COVID-19 outbreak on adolescents' movement behaviors (moderate to vigorous physical activity [MVPA], sleep, recreational screen use, and strengthening exercises). The purpose was to compare movement behavior changes among adolescents affected by the pandemic with controls., Methods: Survey data from 10,659 students at 82 Canadian secondary schools (aged 12-19 y) during the 2018-2019 and 2019-2020 school years were analyzed. One-year change in time spent in movement behaviors and likelihood of meeting Canadian 24-hour movement guidelines was compared between preoutbreak controls (October 2019-March 2020) and early outbreak respondents (May-July 2020) after controlling for sociodemographic factors., Results: Compared with controls, the early outbreak group reported a greater decrease in time spent in MVPA and greater increases in time spent in sleep and recreational screen use. The early outbreak group was less likely to meet MVPA and recreational screen time guidelines but more likely to meet guidelines for strengthening exercises and sleep duration., Conclusions: Findings for MVPA and screen time changes were in the same direction as retrospective reports from children and youth samples. Sleep adherence may have improved due to no longer having to commute to school. Strengthening exercises may represent physical activity that is easier to do in the home with minimal equipment leading to improved adherence during restrictions.

Children's independent mobility (IM) is associated with a range of benefits and understanding the factors that influence IM can support creation of effective interventions. The review (Prospero CRD42016042174) systematically summarized the available literature for social-ecological correlates of children's IM in school-aged children and youth (aged 5-17 years). In this case, 53 studies were included and evaluated six individual, 15 interpersonal, 12 social environment, and 19 built environment- level variables. Most studies originated from Australia ( n = 15) and Canada ( n = 8) with most published in 2011 or later ( n = 48). Variables that were consistently (positively and/or negatively) associated with children's IM were age, ethnicity/race, child's perceived competence, ownership of a house/access to house keys, having siblings, parents' attitude toward IM and perception of child's confidence, children's interest in environment and activities, parents' concern around traffic, housing/residential density, length of residency in one's home, distance to destinations, and proximity to green space. Given the inter-related social-ecological correlates identified, intervention to promote children's IM will likely need a multi-level and multi-sectoral approach. However, focus areas of building children's skills and confidence, helping parents gain confidence in their children's abilities, assuaging parental traffic concerns, and building environments with shorter distances to destinations of interest for children should be prioritized.

Background: There is evidence of school-level variability in children's active behaviors. This study investigated the associations between school environments, policies and practices, and children's physical activity (PA) and active school transportation (AST), in a school ecology context., Methods: We recruited children (N = 1699, age = 10.2 ± 1.0 years, 55.0% girls) in 37 schools from 3 diverse regions of Canada. We then collected data using questionnaires (child, parent) and pedometers. In each school, an official completed a School Health Environment Survey. Multilevel regression models were used to examine associations with children's daily steps, and frequency and volume (frequency*distance) of AST., Results: Between-school variation ranged from 4.7% to 22.2% demonstrating that school environments are associated with children's active behaviors. None of the school environment variables were significantly associated with children's PA or frequency of AST. Nevertheless, their inclusion improved the PA model. Children's volume of AST increased in schools that reported more initiatives to promote AST., Conclusions: Our findings suggest that multiple components are needed to effectively promote active behaviors in children. Schools should determine the areas in which they can improve and assess the feasibility of implementing measures to make their school environments, policies, and practices more conducive to PA and AST., (© 2021 American School Health Association.)

Children who engage in active school transportation (AST) have higher levels of physical activity (PA). Climate and weather were shown to influence adults' daily travel behaviours, but their influence on children's AST and PA has been less examined. This study examined the influence of weather conditions on children's AST and overall PA. Children in grades 4 to 6 ( N = 1699; age, 10.2 ± 1.0 years) were recruited in schools located in urban, suburban and rural areas, stratified by area-level socioeconomic status, in 3 different regions of Canada (Trois-Rivières, Québec; Ottawa, Ontario; Vancouver, British Columbia). Mode of school travel was self-reported and physical activity was measured using a pedometer. We used publicly available data on total precipitation and early morning temperature. AST increased with temperature only among girls. Daily precipitation was negatively associated with boys' and girls' PA while warmer temperature was associated with increased PA on weekend days. We also observed that season and region moderated the relationship between weather conditions and children's physical activity behaviours. Our results suggest that daily weather variations influence children's AST and PA to a greater extent than seasonal variations. Interventions designed to help children and families adapt to weather-related barriers to AST and PA are needed. Novelty: In Canada, weather conditions may influence children's active behaviours daily. Associations between weather conditions, choice of travel mode and physical activity vary by sex, season, and region. Weather affects children's PA differently during the week than on weekends.

Background: In addition to its physical health benefits, physical activity is increasingly recognized as a means to support mental health. Regular moderate-to-vigorous physical activity (MVPA) is associated with improved mental well-being, reduced likelihood of developing mental illness, and improved symptom management. Despite these benefits, most people fail to achieve minimum recommended levels of MVPA. Population levels of physical activity have further declined since the onset of the COVID-19 pandemic and implementation of public health measures (e.g., shelter-in-place protocols). The potential impact of this decline on mental heath outcomes warrants ongoing investigation. Purpose: To investigate associations between changes in MVPA and mental health (depressive symptoms, anxiety symptoms, and life satisfaction) in adults impacted by the COVID-19 pandemic. Method: Research followed a cross-sectional design. English-speaking adults were invited to complete an online questionnaire. MVPA was assessed retrospectively (before COVID-19) and currently (during COVID-19) with the International Physical Activity Questionnaire. Mental health was assessed with the Patient Health Questionnaire, 9-Item (PHQ-9), the Generalized Anxiety Disorder, 7-Item (GAD-7), and the Satisfaction with Life Scale (SWLS). Regression was used to assess relationships between MVPA and mental health. ANOVA with follow-up tests examined whether participants who differed in mental health status (e.g., no symptoms vs. severe symptoms) differed in their change in MVPA. T -tests were used to examine differences in mental health symptomatology between participants who were sufficiently (i.e., achieving MVPA guidelines of ≥ 150 min/week) vs. insufficiently active. Results: Prior to COVID-19, 68.2% of participants were classified as being sufficiently active, vs. 60.6% during COVID-19. The majority of participants reported experiencing some level of depressive symptoms (62.0%) or anxiety symptoms (53.7%). After controlling for covariates, changes in MVPA accounted for significant variability in the PHQ-9 (7.7%), GAD-7 (2.5%), and SWLS (1.5 %). Participants with clinically significant mental health symptomatology reported greater declines in MVPA than those who reported no symptoms. Conversely, participants who were sufficiently active during COVID-19 reported significantly lower depression and anxiety, and higher life satisfaction. Conclusion: Participants who experienced the greatest declines in MVPA reported relatively greater psychological distress and lower life satisfaction. While preliminary, these findings suggest the importance of maintaining and promoting physical activity during a period of pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Gierc, Riazi, Fagan, Di Sebastiano, Kandola, Priebe, Weatherson, Wunderlich and Faulkner.)

While children's independent mobility (CIM) is associated with various benefits, there is evidence of a generational decline in CIM in westernized countries; therefore, it is helpful to understand how CIM is currently negotiated between children and their parents. The purpose of this study was to examine children's and parents' perspectives and negotiations of CIM within the family unit. Face-to-face interviews and walk-along interviews were conducted with parents ( n = 44) and children ( n = 22), respectively. Interviews were audio-recorded and transcribed verbatim, and a thematic analysis was conducted. Four key preconditions were identified that facilitated negotiation of CIM within family units, including (1) the influence of parents' childhood experiences regarding their view of CIM (e.g., positive interpretations of childhood on parenting practices), (2) the role of children's individual characteristics on their independent mobility (e.g., child's confidence in their abilities), (3) family communication as a key coping strategy (parent-parent and parent-child communication), and (4) the influence of positive perceptions of the social environment on CIM. The findings suggest that CIM thrives when these conditions are present; as a result, it may be particularly helpful to develop policies and programs that support children's skill training, explore strategies to support communication between parents and children, and build neighbourhood connections.

The COVID-19 outbreak and related public health guidelines have changed the daily lives of Canadians and restricted opportunities for healthy movement behaviours for children. The purpose of this study was to explore how parents experienced the pandemic-related restrictions and how they impacted their children's movement behaviours. Methods : Twenty-nine semi-structured one-on-one interviews were conducted (June-July 2020) with parents of children (5-11 years old) in Ontario and British Columbia. Interviews lasted between 24-104 min, were audio-recorded, transcribed verbatim, and thematically analyzed. Results : Findings emphasized various individual (e.g., motivation), interpersonal (e.g., parent work schedule), built (e.g., closure of parks) and natural environment (e.g., weather) factors related to children's movement behaviours. The findings highlighted the loss of structured activities and destinations for children's physical activity, and restricted opportunities for outdoor play exacerbated by shrinking childhood independent mobility. Conclusion : Families are adapting to many pandemic-related challenges including adhering to public health restrictions, parents juggling multiple roles, conducting work and school from home, as well as exacerbating factors like weather. It will be important to continue to encourage outdoor time, support policies and practice that facilitate independent mobility, and develop centralized resources that help families in the maintenance of healthy movement behaviours.

Purpose: Children's independent mobility (IM) may facilitate both active transportation (AT) and physical activity (PA), but previous studies examining these associations were conducted in single regions that provided limited geographical variability., Method: We recruited 1699 children (55.0% girls) in 37 schools stratified by level of urbanization and socioeconomic status in 3 regions of Canada: Ottawa, Trois-Rivières, and Vancouver. Participants wore a SC-StepRx pedometer for 7 days and completed a validated questionnaire from which we derived a 6-point IM index, the number of AT trips over a week, and the volume of AT to/from school (in kilometer per week). We investigated relationships among measures of IM, AT, and PA employing linear mixed models or generalized linear mixed models adjusted for site, urbanization, and socioeconomic status., Results: Each unit increase in IM was associated with 9% more AT trips, 19% higher AT volume, and 147 more steps per day, with consistent results across genders. Both measures of AT were associated with marginally higher PA when pooling boys' and girls' data. Children in Vancouver engaged in more AT. PA did not vary across site, urbanization, or socioeconomic status., Conclusion: IM was associated with more AT and PA regardless of where children lived, underscoring a need for IM interventions.

Objectives: Female sport participation is a prioritized action area in the 2018 Canadian federal budget for improving health and well-being. This study examined team sport participation prevalence and longitudinal associations with health-related behaviours among Canadian adolescent girls., Methods: We analyzed data from the COMPASS study. Participants included 1978 female secondary-school students who self-reported the following information at all measurement time-points (grades 9, 10, 11, and 12): socio-demographic, team sport participation status (consistent, intermittent and non-participator), moderate-to-vigorous physical activity (MVPA), dietary behaviours, smoking, cannabis use and binge drinking. Linear mixed models and generalized estimating equation models were used to examine team sport participation status in association with changes in health-related behaviours across grades., Results: The prevalence of team sport participation declined by an average of 38.4% between grades 9 and 12. Proportions of participants being categorized as consistent, intermittent and non-participators were 25.7%, 36.4% and 37.9%, respectively. Compared to non-participators, consistent participators reported significantly greater decline in MVPA (β = - 2.77, 95% CI - 5.36, - 0.18), and the increase in odds of becoming more frequent cannabis users (OR 1.11, 95% CI 1.00, 1.26) and binge drinkers (OR 1.13, 95% CI 1.04, 1.23) was significantly greater. Girls' team sport participation had no significant longitudinal association with dietary behaviours and smoking status., Conclusion: Team sport participation outside of school settings is risky for prospective health-related behaviours in adolescent girls. Our findings highlight the need for investing in tailored participation initiatives that also consider how to prevent harmful substance use.

Globally, physical inactivity is a concern, and children's independent mobility (CIM) may be an important target behavior for addressing the physical inactivity crisis. The aim of this study was to examine correlates of CIM (8-12 years old) in the Canadian context to inform future interventions. CIM was measured via parent surveys. Individual, social, and environmental correlates of CIM were examined using a social-ecological framework. 1699 participants' data were analyzed using descriptive statistics and gender-stratified linear mixed-effects models while controlling for site, area-level socioeconomic status, and type of urbanization. Individual correlates including child grade ( β = 0.612, p < 0.001), language spoken at home ( β = -0.503, p < 0.001), car ownership ( β = -0.374, p < 0.05), and phone ownership ( β = 0.593, p < 0.001) were associated with CIM. For boys, parental gender ( β = -0.387, p < 0.01) was negatively associated with CIM. Parents' perceptions of safety and environment were significantly associated with CIM. Location (i.e., site) was significantly associated with CIM (ref: Trois-Rivières; Ottawa ( β = -1.188, p < 0.001); Vancouver ( β = -1.216, p < 0.001)). Suburban environments were negatively associated with boys' independent mobility ( β = -0.536, p < 0.05), while walkability (400 m β = 0.064, p < 0.05; 1600 m β = -0.059, p < 0.05) was significantly associated with girls' independent mobility only. Future research and interventions should consider targeting "modifiable factors" like children's and parents' perceptions of neighborhood safety and environment.

Background: Active transportation (AT), independent mobility (IM), and outdoor time are promising ways to increase children's physical activity. However, in order to create interventions to increase those forms of physical activity, it is important to understand the relationships between area-level socioeconomic status (SES) and type of urbanization with AT, IM, outdoor time, and physical activity, and this was the aim of the study., Methods: One thousand six hundred ninety-nine children in grades 4 to 6 (mean age: 10.2 ± 1.0 years) from three Canadian regions participated. AT, IM, and outdoor time were assessed using questionnaires and physical activity was measured using the SC-StepRX pedometer. Area-level SES was assessed using the median household income of the census tract in which the school was located and type of urbanization was determined for each school using standardized procedures. Generalized linear and general linear mixed models were used to examine the relationships., Results: Area-level SES and the type of urbanization were generally not related to AT, IM, or physical activity for either gender. However, we observed that both boys and girls living in lower SES areas had decreased odds of spending > 2 h outdoors on weekend days compared to their peers from higher SES areas. Girls living in suburban or rural areas were more likely to spend > 2 h outdoors on weekdays compared to their urban counterparts., Conclusions: AT, IM, and physical activity are generally not associated with area-level SES or the type of urbanization in this sample of Canadian children. The finding regarding outdoor time showing that both boys and girls of lower SES areas had decreased odds of spending > 2 h outdoors on weekends compared to their peers from higher SES areas suggest that additional efforts should be implemented to offer outdoor play opportunities in lower SES areas.
