Background: Reports of children's engagement in active transportation outline low participation rates in many countries despite many associated mental, physical, and social health benefits. One of the main contributors to this phenomenon is a cited lack of education and knowledge among children regarding active travel (AT), specifically road safety. To address this issue, the aim of this study was to evaluate the feasibility and effectiveness of an online road safety education intervention to promote AT among children and their parents., Methods: Applying the Multiphase Optimization Strategy (MOST) for intervention development, implementation, and evaluation, we designed and assessed a four-module online road safety education intervention with a sample of 57 parent-child dyads using a 2 3 factorial design featuring both qualitative and quantitative analyses., Results: Main intervention feasibility findings include positive and critical feedback on the program's content and design, and moderate participant engagement as reflected by program retention and completion rates. With respect to the preliminary intervention effectiveness on children, a significant improvement in road safety knowledge scores was observed for groups that feature the "wheeling safety and skills" module. Slight improvements in AT knowledge scores across all the intervention groups were observed, but were not of significance. Preliminary intervention effectiveness on select parental AT practices and perceptions saw significant improvements in some groups. Groups that featured the 'wheeling safety and skills' module exhibited significantly higher guided choice scores upon completion of the program than those who did not receive this component., Conclusion: The MOST framework allowed us to design and evaluate the feasibility and preliminary effectiveness of an online road safety education intervention. The developed intervention has demonstrated that it has the potential to improve children's road safety knowledge and some areas of parental AT practices and perceptions, to which improvements may be attributed to the inclusion of the "wheeling safety and skills" module, suggesting that the targeted focus on cycling skills is a prioritized area. AT programming and practice implications are discussed. Future research is encouraged to refine modules to better reflect the priorities of children and parents and to test these refined components among larger samples., Word Count: 9,391 (excludes abstract, tables, figures, abbreviations, and references)., (© 2024.

Background: The COVID-19 pandemic has prompted the deployment of digital technologies for public health surveillance globally. The rapid development and use of these technologies have curtailed opportunities to fully consider their potential impacts (eg, for human rights, civil liberties, privacy, and marginalization of vulnerable groups)., Objective: We conducted a scoping review of peer-reviewed and gray literature to identify the types and applications of digital technologies used for surveillance during the COVID-19 pandemic and the predicted and witnessed consequences of digital surveillance., Methods: Our methodology was informed by the 5-stage methodological framework to guide scoping reviews: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarizing, and reporting the findings. We conducted a search of peer-reviewed and gray literature published between December 1, 2019, and December 31, 2020. We focused on the first year of the pandemic to provide a snapshot of the questions, concerns, findings, and discussions emerging from peer-reviewed and gray literature during this pivotal first year of the pandemic. Our review followed the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) reporting guidelines., Results: We reviewed a total of 147 peer-reviewed and 79 gray literature publications. Based on our analysis of these publications, we identified a total of 90 countries and regions where digital technologies were used for public health surveillance during the COVID-19 pandemic. Some of the most frequently used technologies included mobile phone apps, location-tracking technologies, drones, temperature-scanning technologies, and wearable devices. We also found that the literature raised concerns regarding the implications of digital surveillance in relation to data security and privacy, function creep and mission creep, private sector involvement in surveillance, human rights, civil liberties, and impacts on marginalized groups. Finally, we identified recommendations for ethical digital technology design and use, including proportionality, transparency, purpose limitation, protecting privacy and security, and accountability., Conclusions: A wide range of digital technologies was used worldwide to support public health surveillance during the COVID-19 pandemic. The findings of our analysis highlight the importance of considering short- and long-term consequences of digital surveillance not only during the COVID-19 pandemic but also for future public health crises. These findings also demonstrate the ways in which digital surveillance has rendered visible the shifting and blurred boundaries between public health surveillance and other forms of surveillance, particularly given the ubiquitous nature of digital surveillance., International Registered Report Identifier (irrid): RR2-https://doi.org/10.1136/bmjopen-2021-053962., (©Leigha Comer, Lorie Donelle, Bradley Hiebert, Maxwell J Smith, Anita Kothari, Saverio Stranges, Jason Gilliland, Jed Long, Jacquelyn Burkell, Jacob J Shelley, Jodi Hall, James Shelley, Tommy Cooke, Marionette Ngole Dione, Danica Facca.

Background: The coronavirus disease 2019 (COVID-19) pandemic has taken the lives of millions and disrupted countless more worldwide. Simply living through the pandemic has had drastic effects on the health of citizens. Diet, an important aspect of health, has been uniquely affected by the pandemic, although these changes have not been sufficiently studied among youth., Objectives: The objective of this systematic review was to investigate dietary changes of youth during COVID-19., Methods: A prespecified literature review was conducted using MEDLINE, EMBASE, Scopus, and CINAHL to identify studies from January 2020 to May 2023 that assessed dietary changes among youth aged ≤20 y compared with before the pandemic. Only quantitative observational studies that were published in English were included. Two authors completed all screening/study selection independently, with disagreements being resolved via discussion. Data extraction was completed by 1 author. Dietary changes were categorized into food groups and habits for analysis purposes., Results: In total, 67 studies met inclusion criteria. Most studies used recall to assess changes (48/67; 71.6%). Most studies found an increase in fruits and vegetables (24/46; 52.2%), grain products (6/11; 54.5%), meat, poultry, and eggs (4/8, 50.0%), diet quality indices and/or overall dietary assessments (7/13, 53.8%), and the frequency of snacking (9/12; 75.0%), whereas generally finding a decrease in ultraprocessed foods (32/53; 60.4%), compared with before the COVID-19 pandemic. Mixed findings or primarily no changes were found for fish and aquatic products, legumes, beans, seeds and nuts, milk and milk products, breakfast consumption, and nutrient intake., Conclusions: Mostly favorable dietary changes appear to have occurred among youth during COVID-19, although there were several mixed findings and unclear takeaways among the foods and habits under study. The heterogeneity of defining food groups was a noted limitation in the current review., (Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: Cannabis is associated with the onset and persistence of psychotic disorders. Evidence suggests that accessibility of substances is associated with an increased risk of use-related harms. We sought to examine the effect of residing in proximity to non-medical cannabis retailers on the prevalence of health service use for psychosis., Methods: We conducted a cross-sectional study using linked health administrative data, and used geospatial analyses to determine whether people in Ontario, Canada (aged 14-60 years) resided within walking (1.6 km) or driving (5.0 km) distance of non-medical cannabis retailers (open as of February-2020). We identified outpatient visits, emergency department (ED) visits, and hospitalizations for psychotic disorders between 01-April-2019 and 17-March-2020. We used zero-inflated Poisson regression models and gamma generalized linear models to estimate the association between cannabis retailer proximity and indicators of health service use., Results: Non-medical cannabis retailers were differentially located in areas with high levels of marginalization and pre-existing health service use for psychosis. People residing within walking or driving distance of a cannabis retailer had a higher rate of psychosis-related outpatient visits, ED visits, and hospitalizations, compared to people living outside these areas. This effect was stronger among those with no prior service use for psychosis., Conclusions: Proximity to a non-medical cannabis retailer was associated with higher health service use for psychosis, even after adjustment for prior health service use. These findings suggest that opening of non-medical cannabis retailers could worsen the burden of psychosis on mental health services in areas with high-risk populations., Competing Interests: DisclosuresLena Palaniyappan reports personal fees for serving as chief editor from the Canadian Medical Association Journals, speaker/consultant fees from Janssen Canada and Otsuka Canada (2019), SPMM Course Limited, UK, Canadian Psychiatric Association; book royalties from Oxford University Press; investigator-initiated educational grants from Janssen Canada, Sunovion and Otsuka Canada outside the submitted work.

Objectives: Sleep health inequities likely contribute to disparities in health outcomes. Our objective was to identify social determinants of sleep health among middle-aged/older adults in Canada, where prior evidence is limited., Methods: We analyzed cross-sectional data from the Canadian Longitudinal Study on Aging, a survey of over 30,000 community-dwelling adults aged 45-85years. Self-reported measures included sleep duration, sleep satisfaction, and sleep efficiency. We explored associations between sleep measures and social determinants of health. We used modified Poisson regression to estimate prevalence ratios for sleep satisfaction and sleep efficiency, and linear regression for sleep duration. Estimates were adjusted for all social, lifestyle, and clinical covariates. We explored effect modification by sex., Results: Of the 11 social determinants explored, all were significantly associated with at least one domain of sleep health. These associations were reduced to 9 variables with adjustment for all social variables, and 7 with further adjustment for lifestyle and clinical covariates, including differences by sex, age, education, marital status, employment, race/ethnicity, and sexual orientation. Better sleep health in >1 domain was observed among males, older age groups (65 and older), higher income groups, the retired group, and homeowners with adjustment for social variables, and only in males and older age groups with additional adjustment for lifestyle and clinical variables. Only sleep duration associations were modified by sex., Conclusions: Sleep health disparities among Canadian adults exist across socioeconomic gradients and racial/ethnic minority groups. Poor sleep health among disadvantaged groups warrants increased attention as a public health problem in Canada., Competing Interests: Declaration of conflicts of interest The authors have no conflict of interest to disclose., (Copyright © 2024 National Sleep Foundation.

Background: The COVID-19 a pandemic changed the world. Public health directives to socially distance with stay-at-home orders altered injury risk factor exposure, resulting injury patterns and conducting injury prevention (IP). The objective of this study was to determine the impact the COVID-19 pandemic on injury and IP at North American trauma centers (TC)., Results: Sixty-two responses were received from pediatric (44%), adult (11%), and combined (31%) TC, from 22 American states, 5 Canadian provinces and Australia. The majority (91%) of programs targeted age groups from birth to 15 years old. Nearly one-third reported IP to be less of an institutional priority with funding redistributed in 15% of centers [median (IQR) - 25% (- 43, 1)], and resultant staffing changes at 38% of centers. A decrease in IP efforts was reported at 64% of TC. Overall, the majority of respondents reviewed injury data, with the top reported increased mechanisms mainly intentional: Firearm-related (75%), assaults (72%), and abuse (71%). Leading increased unintentional injuries were injuries occurring in the home such as falls (70%), followed by ATV (62%), and cycling (57%). Sites pivoted by presenting (74%) or participating (73%) in IP education virtually, social media posts (61%) and the addition of technology (29%). Top barriers were redeployment of partners (45%) and staff (31%), as well as lack of technology (40%) in the target population. Facilitators were technology at TC (74%), support of trauma program (63%), and having IP funding maintained (55%)., Conclusions: Nearly two-thirds of TC decreased IP efforts during the pandemic due to staffing and funding reductions. The leading reported increased injuries were intentional, indicating that violence prevention is needed, along with support for mental health. While TC successfully pivoted by using technology, access issues in the target population was a barrier resulting in health inequities., (© 2023. The Author(s).)

Objectives: The COVID-19 pandemic has had a profound impact on the daily routines of parents and children. This study explored the influence of socioeconomic status (SES) and urbanicity on parents' attitudes toward their children's active play opportunities 6 months and 1.5 years into COVID-19., Methods: A sample of 239 Ontario parents of children aged 12 and younger completed two online surveys (August-December 2020; 2021) to assess parents' intentions, beliefs, and comforts concerning their child's eventual return to play, in addition to various sociodemographic and physical activity variables. Descriptive analyses were run as well as an exploratory factor analysis (EFA) was conducted to group the 14 attitude items into subscales for analysis, to ensure reliability and validity of attitude measures., Results: In general, parents in communities with more urban features (e.g., densely populated areas), single-parents, full-time employed parents, and parents with lower-incomes were more hesitant to return their children to active play during the pandemic., Conclusion: Findings from this work highlight SES and urbanicity disparities that continue to exist during COVID-19., Competing Interests: 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., (© 2023 The Authors.

Background: COVID-19 caused closures of movement supporting environments such as gyms and schools in Canada. This study evaluated the association between Ontario parents' and children's physical activity levels across time during COVID-19, controlling for variables that were identified as significant predictors of children's and parents' physical activity (e.g., children's age, parents' employment status)., Methods: Parents (n = 243; mean age = 38.8 y) of children aged 12 and under (n = 408; mean age = 6.3 y) living in Ontario, Canada completed 2 online surveys, the first between August and December 2020 and the second between August and December 2021. At baseline, parents were asked to recall prepandemic physical activity levels. To determine the association between parent and child physical activity during COVID-19, a cross-lagged model was estimated to determine the cross-sectional and longitudinal associations between parents' and children's physical activity across time., Results: Bivariate associations revealed that parents' and children's physical activity levels were significantly related during lockdown and postlockdown but not prelockdown. The autoregressive paths from prelockdown to during lockdown were significant for children (β = 0.53, P < .001) and parents (β = 1.058, P < .001) as were the autoregressive paths from during lockdown to postlockdown for children (β = 0.61, P < .001) and parents (β = 0.48, P < .001). In fully adjusted models, the cross-lagged association between parents' physical activity prelockdowns was significantly positively associated with their children's physical activity during lockdowns (β = 0.19, P = .013)., Conclusions: Resources are needed to ensure that children and parents are obtaining sufficient levels of physical activity, particularly during a pandemic.

Background: Urinary stone disease (USD) historically has affected older men, but studies suggest recent increases in women, leading to a near identical sex incidence ratio. USD incidence has doubled every 10 years, with disproportionate increases amongst children, adolescent, and young adult (AYA) women. USD stone composition in women is frequently apatite (calcium phosphate), which forms in a higher urine pH, low urinary citrate, and an abundance of urinary uric acid, while men produce more calcium oxalate stones. The reasons for this epidemiological trend are unknown., Methods: This perspective presents the extent of USD with data from a Canadian Province and a North American institution, explanations for these findings and offers potential solutions to decrease this trend. We describe the economic impact of USD., Findings: There was a significant increase of 46% in overall surgical interventions for USD in Ontario. The incidence rose from 47.0/100,000 in 2002 to 68.7/100,000 population in 2016. In a single United States institution, the overall USD annual unique patient count rose from 10,612 to 17,706 from 2015 to 2019, and the proportion of women with USD was much higher than expected. In the 10-17-year-old patients, 50.1% were girls; with 57.5% in the 18-34 age group and 53.6% in the 35-44 age group. The roles of obesity, diet, hormones, environmental factors, infections, and antibiotics, as well as the economic impact, are discussed., Interpretation: We confirm the significant increase in USD among women. We offer potential explanations for this sex disparity, including microbiological and pathophysiological aspects. We also outline innovative solutions - that may require steps beyond typical preventive and treatment recommendations., 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 © 2023 Filler, Dave, Ritter, Ross, Viprakasit, Hatch, Bjazevic, Burton, Gilleskie, Gilliland, Lin, Jain, McClure, Razvi, Bhayana, Wang, Coulson, Sultan, Denstedt, Fearrington and Diaz-Gonzalez de Ferris.)

Purpose: This study aimed to explore children's lived experiences with the Ontario Student Nutrition Program (OSNP), a free, school-based snack program implemented in elementary schools in Southwestern, Ontario, Canada, to gain insights into future school food programs (SFP). Methods: Focus group discussions (n=17) were conducted with 105 children in Grades 5 to 8 in seven elementary schools. Focus groups were audio-recorded, transcribed, and coded for themes using inductive content analysis. Results: Overall, children appreciated the OSNP and felt that it filled a need in students. Children also reported a willingness to try novel food items. For future SFPs, participants recommended that input be sought from children to ensure food preferences were considered. Children also discussed wanting more appealing food offerings that may include some choice. Finally, children also mentioned wanting a fair and equitable distribution of food in classrooms. Conclusions: Children appreciated the OSNP and reported benefits to themselves and their peers. They also provided some valuable recommendations for future SFPs. If a nationally funded SFP is to be considered in Canada, children expressed the need to make the program equitable, while still allowing schools the flexibility to meet their unique needs and preferences.

Introduction: The COVID-19 pandemic prompted a surge in digital public health surveillance worldwide, with limited opportunities to consider the effectiveness or impact of digital surveillance. The news media shape public understanding of topics of importance, contributing to our perception of priority issues. This study investigated news media reports published during the first year of the pandemic to understand how the use and consequences of digital surveillance technologies were reported on., Methods: A media content analysis of 34 high- to low-income countries was completed. The terms "COVID-19," "surveillance," "technologies," and "public health" were used to retrieve and inductively code media reports., Results: Of the 1,001 reports, most were web-based or newspaper sources on the development and deployment of technologies directed at contact tracing, enforcing quarantine, predicting disease spread, and allocating resources. Technology types included mobile apps, wearable devices, "smart" thermometers, GPS/Bluetooth, facial recognition, and security cameras. Repurposed data from social media, travel cards/passports, and consumer purchases also provided surveillance insight. Media reports focused on factors impacting surveillance success (public participation and data validity) and the emerging consequences of digital surveillance on human rights, function creep, data security, and trust., Discussion: Diverse digital technologies were developed and used for public health surveillance during the first year of the COVID-19 pandemic. The use of these technologies and witnessed or anticipated consequences were reported by a variety of media sources worldwide. The news media are an important public health information resource, as media outlets contribute to directing public understanding and shaping priority public health surveillance issues. Our findings raise important questions around how journalists decide which aspects of public health crises to report on and how these issues are discussed., 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., (© 2023 Comer, Donelle, Ngole, Shelley, Kothari, Smith, Shelley, Stranges, Hiebert, Gilliland, Burkell, Cooke, Hall and Long.)

A child's ability to participate in active school travel (AST) is complicated by several factors. Of particular note are parental controls, which are informed by their perceptions of the local built and social environments, assessments of their child's skills, and convenience preferences, among other considerations. However, there is currently a lack of AST-specific scales that include validated parental perception measures related to such notable barriers and enablers, or those that tend to frame their AST decision-making processes. Framed within the social-ecological model of health behaviour, the aims of the present paper were thus threefold, specifically to (1) outline and test the construct validity of measures delineating parental perceptions of barriers and enablers to AST, (2) evaluate the reliability and consistency of the developed measures, and (3) connect these measures to develop broader constructs for use in the Perceived Active School Travel Enablers and Barriers-Parent (PASTEB-P) questionnaire. To achieve these aims, a mixed-methods approach featuring cognitive interviews and surveys, along with qualitative (thematic analysis) and quantitative (Cohen's Kappa, McDonald's Omega, and confirmatory factor analysis) analyses, was applied across two studies. The validation processes of the two studies resulted in the development of fifteen items comprising seven distinct constructs (barriers: AST Skills, Convenience, Road Safety, Social Safety, and Equipment Storage; enablers: Supportive Environment and Safe Environment) related to parental perceptions of AST. The developed PASTEB-P questionnaire can be used to inform and evaluate AST intervention programming and can be applied for AST research purposes.

Throughout the COVID-19 pandemic, a variety of digital technologies have been leveraged for public health surveillance worldwide. However, concerns remain around the rapid development and deployment of digital technologies, how these technologies have been used, and their efficacy in supporting public health goals. Following the five-stage scoping review framework, we conducted a scoping review of the peer-reviewed and grey literature to identify the types and nature of digital technologies used for surveillance during the COVID-19 pandemic and the success of these measures. We conducted a search of the peer-reviewed and grey literature published between 1 December 2019 and 31 December 2020 to provide a snapshot of questions, concerns, discussions, and findings emerging at this pivotal time. A total of 147 peer-reviewed and 79 grey literature publications reporting on digital technology use for surveillance across 90 countries and regions were retained for analysis. The most frequently used technologies included mobile phone devices and applications, location tracking technologies, drones, temperature scanning technologies, and wearable devices. The utility of digital technologies for public health surveillance was impacted by factors including uptake of digital technologies across targeted populations, technological capacity and errors, scope, validity and accuracy of data, guiding legal frameworks, and infrastructure to support technology use. Our findings raise important questions around the value of digital surveillance for public health and how to ensure successful use of technologies while mitigating potential harms not only in the context of the COVID-19 pandemic, but also during other infectious disease outbreaks, epidemics, and pandemics., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Ultra-processed foods (UPFs) have become a major contributor to the diets of Canadians, with a recent report from Statistics Canada suggesting Canadians are consuming almost one-half of their calories from UPFs. Research has linked UPF consumption with increased risk for chronic diseases such as cardiovascular disease and type 2 diabetes, among others. This paper sought to investigate the popularity of UPFs, particularly among children and teens, utilizing the socioecological model as a framework to illustrate how influences at multiple levels (i.e., public policy, organizational, community, interpersonal, and individual) have played a role in the proliferation of UPFs. Evidence from previous studies is used to identify how factors at different levels may influence UPF consumption and discuss potential strategies for reducing UPF consumption. To meaningfully reduce UPF consumption among Canadians, all levels should be considered, with the goal of creating a healthier Canadian population.

Introduction: Children with disabilities may be unable engage playground spaces due to barriers exacerbating exclusion. Therefore, clarity on how to evaluate existing playgrounds for inclusivity of children with disabilities is required., Methods: A scoping review was undertaken to explore auditing tools., Results: Fourteen white and grey literature resources were identified. The term "inclusion" was operationalized differently across tools, primarily focusing on physical accessibility. Characteristics of the tools were synthesized into 13 inclusive design recommendations for playgrounds. Two tools showed promise, evaluating 12/13 recommendations., Discussion: The results of this review provide guidance on existing tools for evaluating playgrounds for inclusion for community stakeholders and researchers., Systematic Review Registration: https://osf.io/rycmj., 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., (© 2023 Taylor, Primucci, Vanderloo, Arbour-Nicitopoulos, Leo, Gilliland and Tucker.)

The COVID-19 pandemic resulted in closures of physical-activity-supporting environments, including playgrounds, outdoor recreation facilities (e.g., basketball courts), and community centers, which impacted children's movement opportunities. This study evaluated changes in Ontario children's physical activity levels during the COVID-19 pandemic and explored the impact of family sociodemographic markers on children's activity. Parents ( n = 243; M age = 38.8 years) of children aged 12 and under ( n = 408; M age = 6.7 years) living in Ontario, Canada, completed two online surveys between August and December 2020 (survey 1) and August and December 2021 (survey 2). Generalized linear mixed-effects models were used to estimate changes in the proportion of children who accumulated 60 min of physical activity per day pre-lockdown, during lockdown, and post-lockdown in Ontario. Results revealed a significant non-linear trajectory whereby the proportion of children achieving 60 min of physical activity per day pre-lockdown (63%) declined during lockdown (21%) and then increased post-lockdown (54%). Changes in the proportion of children engaging in 60 min of daily physical activity were moderated by several demographic variables. Efforts are needed to provide parents of young children with a wider variety of resources to ensure children are obtaining sufficient levels of physical activity regardless of the presence of community lockdowns.

Some populations have increased risks of experiencing chronic homelessness related to complex health and social needs combined with system failures. Permanent supportive housing (PSH) may improve housing and health outcomes for this population. To understand the scope of the literature on PSH, this scoping review uses Arksey and O'Malley's methodological framework enhanced by Levac and the Joanna Briggs Institute. A search was conducted across multiple databases for existing research on PSH. Forty-one studies were included, and five themes were generated: PSH sustains housing for most people; PSH is costly to implement, but costs can be recouped; PSH facilitates belonging and safety; single-site programs have social challenges but also provide efficiency and improve social networks; and visible on-site staff fundamentally helps those with highest support needs. Permanent supportive housing has been shown to be effective for those with the highest health and social support needs and is required to help prevent and end homelessness.

Background: Breakfast skipping has previously been associated with worse diet quality among adolescents; the latter increases the risk of chronic disease. However, many studies do not consider diet quality as a function of calories, which is problematic as skippers tend to consume less energy than consumers. Additionally, due to the lack of one accepted definition of both breakfast skipping and diet quality, it is unclear how differences found may change when using varying definitions., Objectives: We aimed to compare the Healthy Eating Index-2015 (HEI-2015) scores and nutrient intakes of teen breakfast skippers and consumers in Southwestern Ontario, Canada., Methods: Cross-sectional, baseline data were used from SmartAPPetite, an ongoing nutrition intervention study. Singular 24-h dietary recalls and sociodemographic data from 512 adolescents aged 13-19 y were used to compare HEI-2015 scores and nutrient intakes via multivariable linear regression., Results: Previous day breakfast skippers had significantly lower HEI-2015 scores (-4.4; 95% CI: -8.4, -0.4) and significantly lower intakes of calories, saturated fat, and vitamin C, as well as significantly higher intake of sodium and total fat., Conclusions: Previous day breakfast consumers had significantly higher diet quality scores and better nutrient intakes than breakfast skippers, although, on average, both had poor diet quality. Consequently, it is unlikely that simply advising teens to consume breakfast will result in meaningful change in diet quality, and more effort should be placed on promoting nutritious breakfasts., (© 2023 Published by Elsevier Inc.)

The COVID-19 pandemic and associated public health measures have interrupted the daily routines of parents and children. The purpose of this study was to explore parents' attitudes regarding their children's play/sport during COVID-19. A secondary objective was to explore the influence of parent demographics and parent-reported physical activity levels and risk tolerance on these attitudes. Ontario parents of children aged 12 and younger completed an online survey (August-December 2020) that assessed their attitudes (grouped by support, safety and socialization-related attitudes; n = 14 items) regarding their child(ren)'s play/sport, their physical activity levels ( n = 2 items), and demographic details ( n = 16 items). Two open-ended items were used to gather a deeper understanding of attitudes. Parents' tolerance for risk was measured via the validated Tolerance of Risk in Play Scale. Descriptive statistics were calculated to describe attitudes and risk tolerance. Least Absolute Shrinkage and Selection Operator regressions were conducted to examine factors influencing parents' attitudes. Multiple linear models were computed using the identified predictors for each attitude category. Deductive content analysis was undertaken on open-ended responses. Participants ( n = 819) reported the highest scores for safety-related attitude items ( M = 3.54, SD = .63) followed by socialization and support, which all influenced attitudes regarding children's play/sport (p < .05). Demographics and parents' physical activity levels were identified as important predictors of parents' attitudes. Qualitative data revealed that parents had mixed levels of comfort with respect to their children's return to play/sport. Findings from this study reveal that increased support is needed to guide future play/sport decision-making.

The COVID-19 pandemic has had a large influence on children's physical activity (i.e., play and sport) opportunities. The purpose of this study was to describe parents' perspectives of their children's (ages 0-12) physical activity experiences during the pandemic (i.e., since the onset in March 2020 until follow-up survey completion date [between August to December 2021]). As part of the 'Return to Play' study conducted in Ontario, Canada, two-parent report surveys were completed online via Qualtrics. Surveys measured parents' perspectives regarding their children's physical activity since the onset of the pandemic ( n = 17 items) and collected demographic information ( n = 16 items). Open-ended questions were included to gather a rich understanding of parents' experiences (i.e., supports, challenges) with facilitating their children's physical activity. Descriptive statistics were calculated to describe parents' perspectives of their children's physical activity experiences and to determine parent demographics. Open-ended questions were analyzed via deductive content analysis. Parents ( n = 382) reported that they noticed behavior changes in their children because of the pandemic (65.9%), and most (73.7%) reported challenges with supporting their children's activity during periods when public health measures were in place. Many parents (44.5%) stated that their children asked about returning to play/sport more than three times per week during periods when play/sport facilities were closed in Ontario. Qualitative data identified common supports parents used (e.g., getting active outdoors, forming mini social 'bubbles'), and challenges they faced (e.g., work, children's increased screen time, and home schooling), pertaining to their children's physical activity.

Intervention: Ontario's Harmonized Heat Warning and Information System (HWIS) brings harmonized, regional heat warnings and standard heat-health messaging to provincial public health units prior to periods of extreme heat., Research Question: Was implementation of the harmonized HWIS in May 2016 associated with a reduction in emergency department (ED) visits for heat-related illness in urban locations across Ontario, Canada?, Methods: We conducted a population-based interrupted time series analysis from April 30 to September 30, 2012-2018, using administrative health and outdoor temperature data. We used autoregressive integrated moving average models to examine whether ED rates changed following implementation of the harmonized HWIS, adjusted for maximum daily temperature. We also examined whether effects differed in heat-vulnerable groups (≥65 years or <18 years, those with comorbidities, those with a recent history of homelessness), and by heat warning region., Results: Over the study period, heat alerts became more frequent in urban areas (6 events triggered between 2013 and 2015 and 14 events between 2016 and 2018 in Toronto, for example). The mean rate of ED visits was 47.5 per 100,000 Ontarians (range 39.7-60.1) per 2-week study interval, with peaks from June to July each year. ED rates were particularly high in those with a recent history of homelessness (mean rate 337.0 per 100,000). Although rates appeared to decline following implementation of HWIS in some subpopulations, the change was not statistically significant at a population level (rate 0.04, 95% CI: -0.03 to 0.1, p=0.278)., Conclusion: In urban areas across Ontario, ED encounters for heat-related illness may have declined in some subpopulations following HWIS, but the change was not statistically significant. Efforts to continually improve HWIS processes are important given our changing Canadian climate., (© 2022. The Author(s) under exclusive license to The Canadian Public Health Association.)

Interventions to improve dietary quality and intake of fruits and vegetables (FV) among Canadian children have had modest success, and it has been suggested that food knowledge could be key to improvement. Programs have been criticized for insufficiently connecting food knowledge with food skills and decision making about dietary intake. The objective of this study was to investigate factors associated with FV consumption by elementary school children, aged 9-14 years, in Ontario, Canada, including food knowledge, socioeconomic status, sociodemographic characteristics, and the food environment. In 2017-2019, a cross-sectional survey was administered to 2443 students at 60 elementary schools across Southwestern Ontario (SWO), Canada. A parent survey was used to validate self-reported sociodemographic variables. The mean intake of FV reported by these participants was 2.6 (SD 1.1) and 2.4 (SD 1.2) servings/day, respectively. A FV intake below WHO guidelines was reported by 40.7% of respondents. Knowledge score, child age, and parent employment status significantly predicted higher reported intake of FV. This study shows that FV intake among this population group is low, and increased intake is associated with higher food knowledge. To encourage healthy eating, school-based food and nutrition programs that incorporate multiple components and emphasize food literacy are needed.

To halve per capita global food waste by 2030, policies and programs that effectively reduce household food waste generation are needed. Building upon a previous randomized controlled trial, this study evaluated the long-term effectiveness of the "Reduce Food Waste, Save Money" household food waste reduction intervention by comparing direct measurements of household food waste generated by treatment ( n  = 47) and control households ( n  = 52) over three time periods. The results indicate that there has been a long-term, sustained 30% reduction of avoidable food waste sent to landfill by treatment households following the implementation of this intervention. Additionally, this study assessed the impact of pandemic circumstances on the quantity and composition of household food waste by comparing direct measurements of food waste generated by the same households before (October 2017) and during (June 2020) the COVID-19 pandemic. During the first wave of the pandemic in Ontario, Canada, study households ( n  = 99) sent 2.98 kg of food waste to landfill per week, of which 54% was classified as avoidable food waste, and the remaining 46% as unavoidable food waste. During the pandemic, the generation of unavoidable food waste significantly increased by 65% ( p  < 0.01). There were also significant changes to the composition of wasted food, including a 78% increase in avoidable fruit and vegetables ( p  < 0.01), a 228% increase in avoidable other food ( p  < 0.01), and an 84% increase in unavoidable other food ( p  = 0.02)., Competing Interests: Competing InterestsThe authors declare no competing interests., (© The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Background: COVID-19 has drastically changed the everyday lives of children, including limiting interactions with peers, loss of regularly organized activities, and closure of schools and recreational facilities. While COVID-19 protocols are in place to reduce viral transmission, they have affected children's access to physical activity opportunities. The purpose of this study was to understand how COVID-19 has affected children's engagement in physical activity and to identify strategies that can support children's return to physical activity programming in public places., Methods: Parents of past participants in the Grade 5 ACT-i-Pass Program in London, Ontario, Canada were invited to participate in a semi-structured interview online (in November and December 2020) via Microsoft Teams. The script was comprised of questions about their child's physical activity levels (before, current, and anticipated following COVID-19), lifestyle changes due to COVID-19, and what service providers can do to assist children's return to public programming. Interviews were transcribed in Microsoft Teams, reviewed by a member of the research team, and analyzed in NVivo 12 using thematic analysis., Results: Twenty-seven parents participated in an interview. Four themes and two subthemes were identified during analysis: (1) modifications to everyday life (a. activity options available and b. altered social environment), (2) safety in public spaces, (3) accessibility of activities, and (4) utilizing outdoor spaces., Conclusions: COVID-19 protocols have decreased children's physical activity levels due to the loss of their regular activities, recreational spaces, and peer support. Implementing facility and activity-specific health protocols, providing outdoor activity options, and offering a variety of activity types, times, and locations are three strategies recommended by parents to help facilitate their children's return to public recreational places. Due to the negative consequences of physical inactivity on children's health and well-being, service providers need to implement programming and safety protocols that support children's engagement in physical activity throughout the remainder of, and the years following, the COVID-19 pandemic., (© 2022.

Background: Although playgrounds are designed to promote outdoor play, children with disabilities may be unable to engage in these spaces due to intrinsic and extrinsic factors. Previous research has examined inclusive/accessible playground design when developing new playgrounds; however, it is unclear if there is a best-practice tool for evaluating the inclusivity of existing playground structures., Objective: A scoping review of both peer-reviewed and grey literature will be employed to explore evaluation tools for playground inclusivity, to enable the participation of children with disabilities., Methods: The conduct of this study will adhere to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. A search for peer-reviewed research studies will be conducted in the following electronic databases: MEDLINE, Scopus, CINAHL, and Embase. Grey literature will be examined via a three-step process: (1) a search in the Canadian Health Research Collection Database; (2) a targeted Google search; and (3) reference list searching. Titles, abstracts, keywords, and full texts of identified studies will be independently screened for inclusion by two reviewers. A synthesis of included articles will describe the publication and auditing tool details. A summary of the findings will highlight the types of playgrounds measured, types of disability considered, measures of inclusion used, and psychometric properties., Results: Database searches for peer-reviewed articles were completed in December 2021. A total of 1471 unique records were returned after the removal of 559 duplicate records. Full texts of 167 studies meeting eligibility criteria will be reviewed. The peer-reviewed research search will guide the grey literature search. The scoping review is planned for completion in 2022., Conclusions: A rigorous search of the literature will determine the availability of tools for evaluating existing playground structures for the inclusivity of children with disabilities. The results will inform recommendations on tool applications, and applicable knowledge translation activities., International Registered Report Identifier (irrid): DERR1-10.2196/37312., (©Leah G Taylor, Leigh M Vanderloo, Kelly P Arbour-Nicitopoulos, Jennifer Leo, Jason Gilliland, Patricia Tucker.

There is evidence to suggest that dietary intake of children differs by rural/urban place of residence: rural children may have a higher intake of foods high in fat and sugar than those living in urban environments. The aim of this study was to examine the intake of fruits and vegetables (FV) and the frequency of sugar-sweetened beverage (SSB) consumption, among a sample of rural children in Northern Ontario, Canada, in two different seasons. Sociodemographic factors and children's FV and SSB intake were measured using two repeated cross-sectional surveys, and seasonal information was based on the month of data collection. Logistic regressions were used to examine the odds of children eating five or more FVs, and the odds of 'frequently or always' consuming SSBs. During the fall, children reported eating five or more FV more often, when compared to winter (53.9% vs. 48.3%). In the fall, 25.8% of children reported 'frequently or always' drinking SSB, compared with 16.9% in winter. Indigenous children were less likely to eat five or more FV (OR 0.34 (95% CI 0.12-0.95)) in the fall when compared to non-Indigenous children. Findings indicate that intake of FV among rural students in this region is low, and the frequency of SSB is high, when compared with national recommendations.

Purpose: Knowledge is fundamental to helping children make nutritional choices that support lifelong healthy behaviours. This study ( i ) investigates elementary school children's knowledge about food and nutrition and ( ii ) identifies sociodemographic factors influencing children's reported knowledge. Methods: In 2017-2019, a survey was administered to 2443 students (grades 5-8) at 60 schools across southwestern Ontario, Canada, and a parent survey was used to validate self-reported sociodemographics. Multiple regression was used to analyse children's knowledge scores and related sociodemographic factors. A total knowledge score was calculated by summing correct responses derived from 46 individual questions in the student survey. Results: Mean total knowledge score was 29.2 out of a possible 46 points (63.5% correct). Students demonstrated some knowledge and awareness of strategies to encourage fruit and vegetable consumption, healthy food selection, nutrition, and food preparation skills, although knowledge of food guide recommendations and locally sourced produce were limited. Female sex, family income, and rurality were associated with higher knowledge scores. Conclusions: Results provide insight regarding strengths and gaps in elementary-school children's food and nutrition knowledge. Poor performance of students on specific food guide-related questions suggests that the general guidance of the 2019 Canada's Food Guide might be better understood by children and adolescents.

Research provides evidence of take-home effects in school-based nutrition interventions, citing children as important influencers of family nutrition, acting as agents of change in the household and potentially influencing family food consumption. Therefore, the purpose of this randomized control trial was to examine whether implementation of a centrally procured school food program would produce changes in children's home food environment, including fruit and/or vegetable availability and parental modelling of fruit and/or vegetable consumption. A secondary objective was to investigate whether children's fruit and/or vegetable intake predicted their parent's fruit and/or vegetable intake. A total of 60 schools participated in the evaluation, including 2443 students (and their parents) in grades 5-8. Findings indicated that the intervention did not produce take-home effects on children's home availability of fruit (p = 0.52) and vegetables (p = 0.67) or parental modelling of fruit (p = 0.26) and vegetable consumption (p = 0.78), which may be related to the fact that only food provisions were given. However, children's fruit and vegetable consumption predicted parents' fruit and vegetable consumption (p < 0.001), thereby indicating that children may possess the capacity to influence home nutrition. Future school-based nutrition interventions are recommended to be multi-component (e.g. experiential learning, parent involvement) and that encourage nutrition leadership opportunities for children in the home context., (© The Author(s) 2022.

The purpose of this study was to assess the implementation of a school snack program for children in elementary schools. School-level program volunteers' experiences were explored using semi-structured interviews. Fieldnotes were taken during on-site school visits. Quantitative data were collected through a General Information Form and Weekly Logbooks. Seven elementary schools in Southwestern Ontario were invited and agreed to participate. Interviews ( n = 27) revealed that volunteers valued the program for its universality, the excitement it created, the opportunity for students to try new foods, and the social interactions that it generated. Challenges included the burden on snack volunteers to plan, procure, and prepare foods; the competition the program posed for school priorities; limited funding; and a lack of clear purpose for the program. Suggestions for improvement included providing adequate and sustained resources and an integration of the program into the curriculum. Data obtained from 15 on-site visits, 7 General Information Forms, and 59 (out of a total of 70) Weekly Logbooks confirmed the data obtained from interviews. This research provides insights into the challenges of volunteer-led school snack programs in Canada and may guide policy makers, practitioners, and researchers in the development of a universal, nationally funded school food program.

Background: The COVID-19 pandemic and associated public health measures have resulted in the closure of many physical activity-supporting facilities. This study examined Ontario parents' and children's perspectives of COVID-19's impact on children's physical activity behaviours, return to play/sport during COVID-19, as well as barriers/facilitators to getting active amid extended closures of physical activity venues., Methods: Parents/guardians of children aged 12 years and under living in Ontario, Canada were invited to participate in an interview. 12 parent/guardian and 9 child interviews were conducted via Zoom between December 2020 - January 2021, were audio-recorded, and transcribed verbatim. Thematic content analysis was undertaken to identify pronounced themes., Results: Themes for both parent and child interviews fell into one of three categories: 1) barriers and facilitators for getting children active amid COVID-19 closures of physical activity-supporting facilities; 2) changes in children's activity levels; and, 3) perspectives on return to play/sport during and post-pandemic. Various subthemes were identified and varied between parents and children. The most common facilitator for dealing with children's inactivity voiced by parents/guardians was getting active outdoors. Parents/guardians noted their willingness to have their children return to play/sport in the community once deemed safe by public health guidelines, and children's willingness to return stemmed primarily from missing their friends and other important authority figures (e.g., coaches) and sporting events (e.g., tournaments)., Conclusions: Findings from this study could inform families of feasible and realistic strategies for increasing children's physical activity during community closures, while also providing public health experts with information regarding what supports, or infrastructure might be needed during future lockdown periods and/or pandemics., (© 2021.

COVID-19 public health protocols have altered children's daily routines, limiting their physical activity opportunities. The purpose of this study was to examine how the COVID-19 pandemic affected children's (ages 10-12 years) physical activity and screen time, and to explore the impact of gender, socioeconomic status (SES), and public health constraints (i.e., facility use and social interaction) on the changes in children's health behaviors. Online surveys were disseminated to parents at two time points: before COVID-19 (May 2019 to February 2020) and during COVID-19 (November to December 2020). Wilcoxon signed-rank tests were used to assess changes in physical activity and screen time, and for subgroup analyses. Parents ( n = 95) reported declines in children's physical activity (Z = -2.53, p = 0.01, d = 0.18), and increases in weekday (Z = -4.61, p < 0.01, d = 0.33) and weekend screen time (Z = -3.79, p < 0.01, d = 0.27). Significant changes in physical activity and screen time behaviors were identified between gender, SES, and facility use groups. All social interaction groups underwent significant changes in screen time. Overall, COVID-19 protocols have negatively influenced children's physical activity and screen time. Due to the negative consequences of inactivity and excessive screen time, resources must be made available to support families during the pandemic.

The Rubber Foot Illusion (RFI) is an illusion in which one is made to feel that a model foot is their own through synchronous visuo-tactile stimulation. Previous research suggests that the conditions the RFI can be elicited under are similar to those of the Rubber Hand Illusion (RHI). However, it was unknown if the RFI could be elicited by synchronous movement of a participant's foot and a model foot. To examine this, we developed the Moving Rubber Foot Illusion (mRFI) and compared participants' experience of it to the RFI. The results of this study suggests that the RFI can be elicited through synchronous movement, and results in more proprioceptive drift than a static variant of the RFI. More work is needed to better understand the mechanisms underlying the mRFI.

Introduction: Infectious diseases pose a risk to public health, requiring efficient strategies for disease prevention. Digital health surveillance technologies provide new opportunities to enhance disease prevention, detection, tracking, reporting and analysis. However, in addition to concerns regarding the effectiveness of these technologies in meeting public health goals, there are also concerns regarding the ethics, legality, safety and sustainability of digital surveillance technologies. This scoping review examines the literature on digital surveillance for public health purposes during the COVID-19 pandemic to identify health-related applications of digital surveillance technologies, and to highlight discussions of the implications of these technologies., Methods and Analysis: The scoping review will be guided by the framework proposed by Arksey and O'Malley and the guidelines outlined by Colquhoun et al and Levac et al . We will search Medline (Ovid), PsycInfo, PubMed, Scopus, CINAHL (EBSCOhost), ACM Digital Library, Google Scholar and IEEE Explore for relevant studies published between December 2019 and December 2020. The review will also include grey literature. Data will be managed and analysed through an extraction table and thematic analysis., Ethics and Dissemination: Findings will be disseminated through traditional academic channels, as well as social media channels and research briefs and infographics. We will target our dissemination to provincial and federal public health organisations, as well as technology companies and community-based organisations managing the public response to the COVID-19 pandemic., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Introduction: This study examines correlates of lifetime (ie, ever vaped) and past month vape use among students aged 17 to 19 years, 20 to 25 years, and 26+ years from Western University in London, Ontario. The secondary objective is to assess lifetime and past month vape use among students not of legal age to purchase vaping products in Ontario (ie, those 17 to 18 years only)., Methods: Using Qualtrics, a cross-sectional survey was sent via email to all students at Western University (N = 38 442), assessing their current and past risk-taking behaviors, mental health, sociodemographic characteristics, as well as questions pertaining to their family structure and socioeconomic background during childhood. Students were asked if they had ever vaped in their lifetime and about past month vape use. Logistic regression models were used to assess correlates of lifetime and past month vape use., Results: The sample consisted of 2626 university students. Compared to those ages 26+ years, teenage university students were 10 times more likely to have vaped in the past month and males were twice as likely as females to have vaped. Alcohol use doubled the odds of vaping in the past month, whereas cigarette, cannabis, or cocaine use approximately tripled the odds. Students who reported many sexual partners were far more likely to have vaped in the past month., Conclusion: Vape use is more common among teenage university students, males, those who drink alcohol, smoke, use cannabis or cocaine, and who report many sexual partners., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Objective: Fruits and vegetables (FV) distribution interventions have been implemented as a public health strategy to increase children's intake of FV at school settings. The purpose of this review was to examine whether snack-based FV distribution interventions can improve school-aged children's consumption of FV., Design: Systematic review and meta-analysis of articles published in English, in a peer-reviewed journals, were identified by searching six databases up to August 2020. Standardised mean differences (SMD) and 95 % CI were calculated using a random effects model. Heterogeneity was quantified using I2 statistics., Setting: Population-based studies of interventions where the main focus was the effectiveness of distributed FV as snacks to schoolchildren in North America, Europe and Pacific were included., Results: Forty-seven studies, reporting on fifteen different interventions, were identified; ten studies were included in the meta-analysis. All interventions were effective in increasing children's consumption of FV, with only one intervention demonstrating a null effect. Pooled results under all classifications showed effectiveness in improving children's consumption of FV, particularly for multi-component interventions at post-intervention (SMD 0·20, 95 % CI 0·13, 0·27) and free distribution interventions at follow-up (SMD 0·19, 95 % CI 0·12, 0·27)., Conclusions: Findings suggest that FV distribution interventions provide a promising avenue by which children's consumption can be improved. Nonetheless, our results are based on a limited number of studies, and further studies should be performed to confirm these results. More consistent measurement protocols in terms of rigorous study methodologies, intervention duration and follow-up evaluation are needed to improve comparability across studies.

Background: Good nutrition affects children's health, well-being, and learning, and schools offer an important setting to promote healthy behaviors that can last a lifetime. Once children reach school age, they spend more of their waking hours in school than in any other environment. Children's eating habits may be easier to influence than those of adults. In Canada, households with children are more likely to experience food insecurity, and school food programs that are universally available to all children can support the development of healthy eating patterns across groups of varying socioeconomic status. There is a significant gap in the rigorous community-engaged academic research on the impact of school meal programs, especially universal ones., Objective: The aim of this population health intervention research is to study the impact of a 2-year universal, curriculum-integrated healthy school lunch program in elementary schools in Saskatoon, Saskatchewan, Canada, on food consumption, dietary quality and food and nutrition-related knowledge, attitudes, and practices., Methods: This population health intervention study will be conducted in 2 intervention elementary schools matched with 2 control schools. We will collect preintervention data, including objective measurements of food eaten at school and food-related knowledge, attitudes, and behaviors. This will be followed by the intervention itself, along with qualitative case studies of the intervention process in the 2 intervention schools. Then, we will collect postintervention data similar to the preintervention data. Finally, we will finish the data analysis and complete the ongoing sharing of learning from the project., Results: This study was funded in April 2020 but because of the COVID-19 pandemic, data collection did not begin until May 2021. The intervention will begin in September 2021 and end in June 2023, with end point data collection occurring in May and June 2023. The case study research will begin in September 2021 and will be ongoing for the duration of the intervention., Conclusions: The opportunity we have to systematically and comprehensively study a curriculum-integrated school lunch program, as well as the promising practices for school food programs across Canada, is without precedent., International Registered Report Identifier (irrid): DERR1-10.2196/30899., (©Rachel Engler-Stringer, Jennifer Black, Nazeem Muhajarine, Wanda Martin, Jason Gilliland, Janet McVittie, Sara Kirk, Hannah Wittman, Amin Mousavi, Sinikka Elliott, Sylvana Tu, Brent Hills, Gordon Androsoff, Debbie Field, Brit Macdonald, Chelsea Belt, Hassan Vatanparast.

Background: Patients with interstitial lung disease (ILD) are known to have diminished exercise ability. This study aimed to explore the relationship between nutrition status and body composition parameters with exercise capacity in ILD patients. A second aim focused on assessing the appropriateness of surrogate markers of nutrition status in ILD patients., Methods: Disease severity was determined by the percentage of predicted forced vital capacity. Exercise capacity was determined using 6-minute walk distance. Nutrition status was assessed using the subjective global assessment (SGA), standardized phase angle (SPhA), and impedance ratio z-score (z-IR). Bioelectrical impedance analysis estimated body composition parameters., Results: 45 of 79 participants (57%) were malnourished according to the SGA. FFM index z-score (z-FFMI) (r = 0.42, P = .02) and SGA (r = 0.49, P < .01) were significant predictors of exercise capacity independent of disease severity. Age (odds ratio [OR] = 1.1; 95% CI, 1.01-1.25; P = .04), low body mass index (OR = 0.73; 95% CI, 0.57-0.92; P = .01), z-FFMI (OR = 0.34; 95% CI, 0.17-0.68; P < .01), and body fat mass index z-score (OR = 0.39; 95% CI, 0.17-0.91; P = .03) were significantly associated with severe malnutrition. There was no significant difference in SPhA across SGA groups; however, a higher z-IR (poorer cell health) significantly increased the odds of severe malnutrition (OR = 2.75; 95% CI, 1.27-6.03; P = .02)., Conclusion: In ILD patients, malnutrition and loss of FFM negatively impact the ability to perform activities of daily living., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Food literacy is a set of skills and knowledge that are integral to diet. It is common among teenagers to not have basic food literacy skills needed to consume a healthy diet. This study examined: (1) the current state of food and nutrition knowledge among adolescents 13-19 years of age in the census metropolitan area of London, ON, Canada; and (2) correlates of food knowledge and nutrition knowledge among adolescents. Data for this study were drawn from baseline youth and parent survey data collected from a larger population health intervention study. Statistical analysis of the survey data indicates that higher parental education and higher median neighbourhood family income, the use of mobile health applications, liking to cook, as well as confidence in reading and understanding food labels were all consistently associated with increased food and nutrition knowledge. Findings may help guide future research towards optimal methods for delivering food literacy interventions to effectively educate teenagers. Results of this study may help guide policy makers, researchers, and public health professionals in developing appropriate food and nutrition programs and curriculums to combat the decline in food literacy skills.

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.

Background: Cell phone use while driving (CPWD) increases the risk of crashing and is a major contributor to injuries and deaths. The objective of this study was to describe the evaluation of a multifaceted, evidence-based population health strategy for the reduction of distracted driving., Methods: A multipronged campaign was undertaken from 2014 to 2016 for 16- to 44-year-olds, based on epidemiology, focused on personal stories and consequences, using the "Es" of injury prevention (epidemiology, education, environment, enforcement, and evaluation). Education consisted of distracted driving videos, informational cards, a social media AdTube campaign, and a movie theater trailer, which were evaluated with a questionnaire regarding CPWD attitudes, opinions, and behaviors. Spatial analysis of data within a geographic information system was used to target advertisements. A random sample telephone survey evaluated public awareness of the campaign. Increased CPWD enforcement was undertaken by police services and evaluated by ARIMA time series modeling., Results: The AdTube campaign had a view rate of >10% (41,101 views), slightly higher for females. The top performing age group was 18- to 24-year-olds (49%). Our survey found 61% of respondents used handheld CPWD (14% all of the time) with 80% reporting our movie trailer made them think twice about future CPWD. A stakeholder survey and spatial analysis targeted our advertisements in areas of close proximity to high schools, universities, near intersections with previous motor vehicle collisions, high traffic volumes, and population density. A telephone survey revealed that 41% of the respondents were aware of our campaign, 17% from our print and movie theater ads and 3% from social media. Police enforcement campaign blitzes resulted in 160 tickets for CPWD. Following campaign implementation, there was a statistically significant mean decrease of 462 distracted driving citations annually (p = 0.001)., Conclusion: A multifaceted, evidence-based population health strategy using the Es of injury prevention with interdisciplinary collaboration is a comprehensive method to be used for the reduction of distracted driving., Level of Evidence: Therapeutic, level IV., (Copyright © 2020 Wolters Kluwer Health, Inc.

Objective: The objective was to examine the influence of weather on moderate-to-vigorous physical activity (MVPA) and light physical activity (LPA) levels of children aged 8-14 years from rural communities, an understudied Canadian population., Methods: Children (n = 90) from four communities in rural Northwestern Ontario participated in this study between September and December 2016. Children's MVPA and LPA were measured using an Actical accelerometer and demographic data were gathered from surveys of children and their parents. Weather data were collected from the closest weather station. Cross-classified regression models were used to assess the relationship between weather and children's MVPA and LPA., Results: Boys accumulated more MVPA than girls (b = 26.38, p < 0.01), children were more active on weekdays as compared with weekends (b = - 16.23, p < 0.01), children were less active on days with precipitation (b = - 22.88, p < 0.01), and higher temperature led to a significant increase in MVPA (b = 1.33, p  < 0.01). As children aged, they accumulated less LPA (b = - 9.36, p < 0.01) and children who perceived they had higher levels of physical functioning got more LPA (b = 25.18, p = 0.02). Similar to MVPA, children had higher levels of LPA on weekdays (b = - 37.24, p < 0.01) as compared to weekend days and children accumulated less LPA (b = -50.01, p < 0.01) on days with rain., Conclusion: The study findings indicate that weather influences rural children's MVPA and LPA. Future research is necessary to incorporate these findings into interventions to increase rural children's overall PA levels and improve their overall health.

Background: Literature focusing on nutritional variables and survival in interstitial lung disease (ILD) is limited by its focus on weight and BMI and has not considered body composition., Objectives: The primary objective of this study was to examine whether body composition measures, specifically fat-free mass index z-score (z-FFMI) and body fat mass index z-score (z-BFMI), were predictors of survival in fibrotic ILD patients. The second objective was to examine if nutrition status was a predictor of survival., Method: Seventy-eight outpatients diagnosed with fibrotic ILD were recruited in this cross-sectional study. Body composition data using dual frequency bioelectrical impedance analysis (BodyStat 1500MD; UK) and nutrition status using the subjective global assessment (SGA) were determined. To control for age and sex, z-FFMI and z-BFMI were calculated using population means. Participant charts were reviewed for diagnosis, age, disease severity, and exercise capacity., Results: Age (HR 1.08, 95% CI [1.03-1.13], p < 0.01), BMI (HR 0.90, 95% CI [0.84-0.97], p < 0.01]), z-FFMI (HR 0.70, 95% CI [0.56-0.87], p = 0.02), z-BFMI (HR 0.74, 95% CI [0.57-0.96], p < 0.01), 6-min walk distance (6MWD) (HR 0.99, 95% CI [0.99-1.00], p < 0.01), percent predicted diffusing capacity for carbon monoxide (%DLco) (HR 0.93, 95% CI [0.89-0.97], p < 0.01), and severe malnutrition (SGA-C) (HR 6.98, 95% CI [2.00-24.27], p < 0.01) were significant predictors of survival.

Background: Several studies demonstrate that the provision of personalized lifestyle advice, based on genetics, can help motivate individuals to engage in greater nutrition and physical activity changes compared to the provision of population-based advice. The theoretical mechanism behind this phenomenon is poorly understood. The objective of this study was to determine the impact of providing genetically tailored and population-based lifestyle advice on key constructs of the Theory of Planned Behaviour (TPB)., Materials and Methods: A pragmatic, cluster randomized controlled trial ( n = 140) took place at the East Elgin Family Health Team, in Aylmer, Ontario, Canada. Participants were primarily Caucasian females enrolled in a weight management program (BMI ≥ 25.0 kg/m 2 ). Weight management program groups were randomized (1:1) to receive a population-based lifestyle intervention for weight management (Group Lifestyle Balance™ (GLB)) or a lifestyle genomics (LGx)-based lifestyle intervention for weight management (GLB+LGx). Attitudes, subjective norms and perceived behavioural control were measured at baseline, immediately after receiving a report of population-based or genetic-based recommendations and after 3-, 6- and 12-month follow-ups. Linear mixed models were conducted, controlling for measures of actual behavioural control. All analyses were intention-to-treat by originally assigned groups., Results: Significant changes ( p < 0.05) in attitudes, subjective norms, and perceived behavioural control tended to be short-term in the GLB group and long-term for the GLB+LGx group. Short-term and long-term between-group differences in measures of subjective norms were discovered, favouring the GLB+LGx group., Conclusions: The TPB can help provide a theoretical explanation for studies demonstrating enhanced behaviour change with genetic-based lifestyle interventions., Clinical Trial Registration: NCT03015012.

Despite the importance of process evaluation in program evaluations, research has focused primarily on the effectiveness of fruit and vegetables (FVs) distribution interventions on children's consumption, with little attention given to how these interventions achieve their outcomes. Five bibliographic databases (Embase, PubMed, ProQuest, Scopus, and Web of Science Core Collection) were searched in June 2019 for studies of interventions where the main focus was the implementation of distributed FVs to school-aged children as a snack. The Critical Appraisal Skills Programme (CASP) tool was used to appraise the risk of bias within included studies. Data were extracted based on study characteristics and findings. Results identified 24 studies reporting on 11 interventions and 1 policy. The findings of this systematic review indicate that the majority of the studies included limited references to implementation research. Recurring limitations include an absence of an evaluation theoretical framework and the data collection methods used. Also, several factors were identified as informing the success of snack-based FVs distribution programs, including participation of the school community, school characteristics, background knowledge, and parental engagement. Lack of timely FVs delivery, limited funding, inadequate awareness about the program, insufficient teachers' time, and food waste were identified as challenges to successful programming. Findings indicate that distributing FVs to school-aged children as a snack can increase their consumption, but only with proper implementation. Further evaluative research is required to better inform future implementation of snack-based FV distribution interventions in school settings., Competing Interests: 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., (© 2020 The Authors.)

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.

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.

This systematic review explores experiences of household food insecurity in rural areas of developed countries. A search of 5 databases resulted in 32 peer-reviewed articles for inclusion. Data were analyzed using directed content analysis to broaden the understanding of rural household food insecurity. Elements of food security (ie, availability, accessibility, acceptability, adequacy, and agency) were exemplified across the literature. In addition, 4 key themes were found: exercising human capital, realizing social capital, coping with compounding stressors, and navigating complex systems. This review demonstrates the need for interventions that improve social connectedness, individual coping skills, and system navigation.

Background: The use of nutrigenomics and lifestyle genomics in clinical practice has the potential to optimize weight-related outcomes for patients., Aim: A scoping review was conducted to summarize and evaluate the current body of knowledge related to the effectiveness of providing DNA-based lifestyle advice on weight-related outcomes, with the aim of providing direction for future research., Method: Primary studies were included if they were written in English, evaluated weight-related and/or body mass index and/or body composition outcomes, and provided participants with an actionable genetic-based lifestyle intervention; interventions that only provided information on genetic risk for diseases/conditions were excluded. Data was extracted from each article meeting inclusion criteria ( N =3) and the studies were critically appraised for methodological limitations., Results: Research in this area is promising, but limited. Specific limitations relate to study designs, the nature of the recommendations provided to participants, small (underpowered) sample sizes, the use of self-reported weight/BMI data and lack of consideration of important confounding factors., Conclusions: Therefore, the effectiveness of nutrigenomics and lifestyle genomics interventions for weight management in clinical practice cannot yet be conclusively determined. Recommendations for future research are detailed in the present manuscript.
