Objective: This study examined the rate of caries-related dental treatments under general anesthesia (GA) in fluoridated and non-fluoridated communities in Alberta, Canada, between 2010 and 2019.

Methods: This retrospective, population-based study included all children ( $<$ 12 years of age) living in Calgary (non-fluoridated) and Edmonton (fluoridated) who underwent caries-related dental treatments under GA at publicly funded facilities. Demographics and dental data were extracted from health administrative databases for three time periods of 2010/11 (pre-cessation), 2014/15, and 2018/19 (post-cessation).

Results: Among 2659 children receiving caries-related treatments under GA, the mean (SD) and median (IQR) age were 4.8 (2.3) and 4 (3-6) years, respectively, and 65% resided in the non-fluoridated area. The analysis revealed that the cessation of water fluoridation was significantly associated with an increased rate of caries-related GA events per 10,000 children in both age groups (0-5 and 6-11 years), with a more pronounced effect in 0-5-year-olds in non-fluoridated areas. The risk of dental treatments under GA was also positively associated with post-cessation time.

Conclusion: Discontinuing water fluoridation appears to negatively affect young children's oral health, potentially leading to a significant increase in caries-related dental treatments under GA and oral health disparities in this pediatric population.

Daylight Saving Time (DST) is the practice of setting the clocks one hour forward from Standard Time (ST) in the spring and back again to ST in the fall. This commentary discusses the impact of bi-annual time changes on sleep and circadian rhythms and suggests avenues to minimize negative outcomes on the well-being of Canadian citizens. Ideally, ST should be close to solar time, meaning that daylight is equally distributed before and after noon time, i.e., when the sun is at its highest point in the sky. In Canada, some provinces are proposing to opt out of DST to either return to constant ST throughout the year or to implement permanent DST. National and international associations of clinicians and researchers on sleep and biological rhythms and in health sciences have positioned themselves in favour of permanent ST. In Canada, the Canadian Sleep Society and the Canadian Society for Chronobiology have also issued such a position. This commentary focuses on the implications of previous research findings for sleep and health in Canada given its northern geographical location. It concludes with a research agenda focusing on the Canadian context.

Objectives: Cancer is a leading cause of death among people living with intellectual or developmental disabilities (IDD). There is little empirical evidence documenting survival or comparing outcomes to those without IDD. This study investigated the association between IDD and cancer survival among adults with breast (female), colorectal, or lung cancer.

Methods: A population-based retrospective cohort study was conducted in Ontario, Canada, with routinely collected data. Patients with breast, colorectal, or lung cancer were included (2007‒2019). IDD status before cancer was determined using an established administrative data algorithm. The outcomes of interest included death from any cause and death from cancer. Cox proportional hazards models and competing events analyses using multivariable cause-specific hazards regression were completed. Analyses were stratified by cancer type. Interactions with age, sex, and stage at diagnosis, as well as sensitivity analyses, were completed.

Results: The final cohorts included 123,695 breast, 98,809 colorectal, and 116,232 lung cancer patients. Individuals with IDD experienced significantly worse survival than those without IDD. The adjusted hazard ratios of all-cause death were 2.74 (95% CI 2.41‒3.12), 2.42 (95% CI 2.18‒2.68), and 1.49 (95% CI 1.34‒1.66) times higher for breast, colorectal, and lung cancer patients with IDD relative to those without. These findings were consistent for cancer-specific deaths. With few exceptions, worse survival for people with IDD persisted regardless of stage at diagnosis.

Conclusion: People with IDD experienced worse cancer survival than those without IDD. Identifying and intervening on the factors and structures responsible for survival disparities is imperative.

The One Health concept has acquired increasing attention due to the COVID-19 pandemic. We argue for a health promotion perspective that frames One Health in terms of positive health for people, animals, and ecosystems and includes a spiritual-cosmological dimension. This would enhance policy, research, and practice across disciplines and sectors for a more resilient and harmonious planet.

Objectives: High levels of sedentary time (ST) are associated with poor physical and mental health. Given that Canadians spend a large portion of their days at school and work, they may be important targets for reducing ST. Our objectives are to estimate the daily amount of school and work ST among Canadians, examine differences by subgroups, and determine associations with health.

Methods: Using the 2020 Canadian Community Health Survey Healthy Living Rapid Response module (N = 5242), the amount of time spent sitting while at school and work was estimated among youth (12-17 years) and adults (18-34 and 35-64 years). Differences by sociodemographics and 24-Hour Movement Guideline adherence were assessed with independent t-tests. Associations between school and work ST and health indicators were assessed using adjusted logistic regression.

Results: Canadian youth aged 12-17 years and adults aged 18-34 years reported an average of 4.5 and 5.2 h/day of school ST, respectively. Adults 18-34 years and 35-64 years reported an average of 3.9 and 4.0 h/day of work ST, respectively. School and work ST differed within several subgroups. Among adults 18-34 years, higher school ST was associated with a reduced odds of 'excellent/very good' mental health, whereas higher work ST was associated with a greater likelihood of reporting 'excellent/very good' general health.

Conclusion: Canadian youth and working-age adults report an average of 4-5 h/day sedentary at school or work. This is the first study estimating school and work ST in a representative sample of Canadians and will aid in increasing awareness of setting-specific behaviours to better inform targeted interventions including addressing inequalities in ST.

Objective: The study objective is to measure the influence of psychological antecedents of vaccination on COVID-19 vaccine intention among citizens of the Métis Nation of Ontario (MNO).

Methods: A population-based online survey was implemented by the MNO when COVID-19 vaccines were approved in Canada. Questions included vaccine intention, the short version of the "5C" psychological antecedents of vaccination scale (confidence, complacency, constraint, calculation, collective responsibility), and socio-demographics. Census sampling via the MNO Registry was used achieving a 39% response rate. Descriptive statistics, bivariate analyses, and multinomial logistic regression models (adjusted for sociodemographic variables) were used to analyze the survey data.

Results: The majority of MNO citizens (70.2%) planned to be vaccinated. As compared with vaccine-hesitant individuals, respondents with vaccine intention were more confident in the safety of COVID-19 vaccines, believed that COVID-19 is severe, were willing to protect others from getting COVID-19, and would research the vaccines (Confident OR = 19.4, 95% CI 15.5-24.2; Complacency OR = 6.21, 95% CI 5.38-7.18; Collective responsibility OR = 9.83, 95% CI 8.24-11.72; Calculation OR = 1.43, 95% CI 1.28-1.59). Finally, respondents with vaccine intention were less likely to let everyday stress prevent them from getting COVID-19 vaccines (OR = 0.47, 95% CI 0.42-0.53) compared to vaccine-hesitant individuals.

Conclusion: This research contributes to the knowledge base for Métis health and supported the MNO's information sharing and educational activities during the COVID-19 vaccines rollout. Future research will examine the relationship between the 5Cs and actual uptake of COVID-19 vaccines among MNO citizens.

Objectives: This study aimed to apply a systems thinking approach to explore factors influencing the detection of emerging drug trends in Canada's provinces and territories to better understand how the local context can influence the design and performance of a pan-Canadian (i.e., national) substance use early warning system (EWS). This study also presents a set of actionable recommendations arising from the results. METHODOLOGY AND METHODS: Semi-structured interviews were conducted with 13 purposively recruited Medical Officers of Health and epidemiologists from across Canada working in the field of substance use. Thematic and social network analysis guided by the socio-technical systems framework were subsequently employed.

Results: Barriers and facilitators for detecting emerging drug trends in provinces and territories are a product of the collective linkages and interactions between social (objectives, people, culture), technical (tools, practices, infrastructure), and external environmental (financial, regulatory frameworks, stakeholders) factors. Shortcomings in several of these areas shaped the system's behaviour and together contributed to fragmented operations that lacked strategic focus, poorly designed cross-sector partnerships, and unactionable information outputs. Participants' experiences shaped perceptions of a national substance use EWS, with some voicing potential opportunities and others expressing doubts about its effectiveness.

Conclusion: This study highlights interconnected social, technical, and external environmental considerations for the design and implementation of a national substance use EWS in Canada. It also demonstrates the value of using the socio-technical systems framework to understand a complex public health surveillance issue and how it can be used to inform a path forward.

Objectives: Young adults are disproportionately affected by sexually transmitted and blood-borne infections (STBBIs), and rates of STBBI screening in this population are persistently low. The present study examined the effectiveness of Club Sexu's social marketing campaign, DépistaFest, in increasing STBBI screening, screening intentions, and general STBBI and STBBI screening knowledge among young adults in Quebec, Canada. Grounded in the health belief model, the campaign provided practical and scientifically accurate information on STBBIs and screening using an inclusive, positive, and playful approach.

Methods: A sample of 686 participants (M = 28.0 years old) was recruited through Club Sexu's social media to complete an online survey assessing campaign exposure, recent STBBI screening, screening intentions, and general STBBI and screening knowledge. Logistic regressions and ANCOVAs were performed to examine group differences on outcome variables.

Results: Compared to nonexposed participants, those who were exposed to the campaign were 2.11 times more likely to report having been tested in the past 6 months, and 2.07 times more likely to report planning to get tested in the next 6 months. Exposed participants were also more likely to correctly answer general STBBI knowledge questions and reported higher levels of self-perceived STBBI screening knowledge than nonexposed participants.

Conclusion: The findings support the effectiveness of an STBBI prevention campaign grounded in the health belief model. Future STBBI prevention campaigns aimed at young adults would benefit from destigmatizing STBBIs and normalizing STBBI screening using an inclusive, positive, and playful approach.

Objectives: Few are the longitudinal studies on the changes in moderate or severe symptoms of anxiety or depression (MSS-ANXDEP) from before to during the COVID-19 pandemic in Canada. The aim was to study the change in MSS-ANXDEP and associated sociodemographic, economic, psychosocial, health behaviour and lifestyle, and clinical factors.

Methods: The current sample includes 59,997 adults aged ≥ 35 years participating in the 2018 and 2020 health surveys of the 5 established cohorts of the Canadian Partnership for Tomorrow's Health (CanPath). MSS-ANXDEP was based on a cutoff score ≥ 10 on the 7-item Generalized Anxiety Disorder Scale and Patient Health Questionnaire (PHQ-8). Change in MSS-ANXDEP was categorized as follows: no MSS-ANXDEP, remitted, incident, and persistent. Multinomial regressions were used to study MSS-ANXDEP as a function of sociodemographic, economic, psychosocial, health behaviours and lifestyle, and clinical factors.

Results: Sociodemographic and economic (i.e. age, gender, cohort, race/ethnicity, lower income, decreased in income, work status, being an essential worker), lifestyle and health behaviours (i.e. smoking, cannabis and alcohol use, drinking more alcohol), psychosocial (i.e. provide help to others, information and instrumental support, and change in relationships with friends, family, and partner) and clinical factors (i.e. lifetime mental disorder and multimorbidity) were associated with remitted, incident, and persistent MSS-ANXDEP.

Conclusion: Health and socio-economic factors were associated with changes in symptoms of anxiety and depression during the pandemic, further increasing inequities in mental health needs. Public health campaigns on the importance of healthy behaviours should continue and health policies should reduce economic and social barriers to integrated substance use and mental health care.
