The effect modification of extreme temperatures on mental and behavior disorders by environmental factors and individual-level characteristics in Canada.

Objective: Ambient extreme temperatures have been associated with mental and behavior disorders (MBDs). However, few studies have assesed whether vulnerability factors such as ambient air pollution, pre-existing mental health conditions and residential environmental factors increase susceptibility. This study aims to evaluate the associations between short-term variations in outdoor ambient extreme temperatures and MBD-related emergency department (ED) visits and how these associations are modified by vulnerability factors.

High Temperatures and Cardiovascular-Related Morbidity: A Scoping Review.

The primary objective of this review was to synthesize studies assessing the relationships between high temperatures and cardiovascular disease (CVD)-related hospital encounters (i.e., emergency department (ED) visits or hospitalizations) in urban Canada and other comparable populations, and to identify areas for future research.

Does the definition of preventable emergency department visit matter? An empirical analysis using 20 million visits in Ontario and Alberta.

Objectives: This study had two objectives: (1) to estimate the prevalence of preventable emergency department (ED) visits during the 2016-2020 time period among those living in 19 large urban centers in Alberta and Ontario, Canada, and (2) to assess if the definition of preventable ED visits matters in estimating the prevalence.

Methods: A retrospective, population-based study of ED visits that were reported to the National Ambulatory Care Reporting System from April 1, 2016, to March 31, 2020, was conducted. Preventable ED visits were operationalized based on the following approaches: (1) Canadian Triage and Acuity Scale (CTAS), (2) ambulatory care-sensitive conditions (ACSC), (3) family practice-sensitive conditions (FPSC), and (4) sentinel nonurgent conditions (SNC).

Multimorbidity in large Canadian urban centres: A multilevel analysis of pooled 2015-2018 cross-sectional cycles of the Canadian Community Health Survey.

Background: There is limited knowledge on how the prevalence of multimorbidity varies within and across major Canadian urban centres. The objective of this study was to investigate the between-neighbourhood variation in the prevalence of multimorbidity in Canada's large urban centres, controlling for compositional effects associated with individual-level demographic and socioeconomic factors.

Methods: Cross-sectional data from the 2015-2018 cycles of the Canadian Community Health Survey (CCHS) were pooled at the microdata level.

Extreme heat and paediatric emergency department visits in Southwestern Ontario.

Objective: The risk of adverse health events is expected to increase with hotter temperatures, particularly among the most vulnerable groups such as elderly persons and children. The objective of this study was to assess the association between extreme heat and daily emergency department visits among children (0 to 17 years) in Southwestern Ontario.

Methods: We examined the average maximum temperature, relative humidity, and daily paediatric emergency department visits in June through August of 2002 to 2019.

Is Prosocial Behavior Associated With Increased Registration for Deceased Organ Donation? A Cross-sectional Study of Ontario, Canada.

Unlabelled: A community that promotes prosocial behaviors such as organ donor registration or charitable giving could reinforce those behaviors among its residents. Understanding the nature of the relationship between prosocial behaviors at the community level and an individual's decision to engage in prosocial behavior can help in the targeting of communities with lower rates of prosocial activities. The objective of this study was to assess if the likelihood that an individual is a registered deceased organ donor in Ontario, Canada, is associated with community-level charitable giving.

Geographic variation in preventable hospitalisations across Canada: a cross-sectional study.

Objective: The objective of this study is to examine the magnitude and pattern of small-area geographic variation in rates of preventable hospitalisations for ambulatory care-sensitive conditions (ACSC) across Canada (excluding Québec).

Design And Setting: A cross-sectional study conducted in Canada (excluding Québec) using data from the 2006 Canadian Census Health and Environment Cohort (CanCHEC) linked prospectively to hospitalisation records from the Discharge Abstract Database (DAD) for the three fiscal years: 2006-2007, 2007-2008 and 2008-2009.

Primary Outcome Measure: Preventable hospitalisations (ACSC).

Geographic variation in short and long sleep duration and poor sleep quality: a multilevel analysis using the 2015-2018 Canadian community health survey.

Background: There is a dearth of evidence on geographic variation in sleep duration and quality, and about the effect of geographic location or "place" on sleep. The objective was to assess the magnitude of geographic variation in sleep duration and sleep quality in Canada, while controlling for individual-level factors.

Methods: Data from the 2015-2018 cycles of the Canadian Community Health Survey were used.

Exploring Spatial Variation in Registration for Deceased Organ Donation in Ontario, Canada.

Deceased organ donor registration rates vary within Ontario. We conducted a spatial analysis to assess how organ donor registration rates are patterned across Ontario and whether efforts to increase registrations have been successful. Statistically significant and substantial spatial variation was apparent, with geographic clusters of higher- and lower-than-average registration rates.

Residential schools and the effects on Indigenous health and well-being in Canada-a scoping review.

Background: The history of residential schools has been identified as having long lasting and intergenerational effects on the physical and mental well-being of Indigenous populations in Canada. Our objective was to identify the extent and range of research on residential school attendance on specific health outcomes and the populations affected.

Methods: A scoping review of the empirical peer-reviewed literature was conducted, following the methodological framework of Arksey and O'Malley (2005).

Exploring Mothers' Influence on Preschoolers' Physical Activity and Sedentary Time: A Cross Sectional Study.

Objectives Physical activity patterns can track from childhood into adulthood; therefore, establishing active behaviors early is imperative. Given the multidimensional nature of a mother's influence on their children, there is a need to utilize more comprehensive measures to assess the relationship between mother and child activity behaviors. Specifically, mothers have been identified as influencing preschoolers' activity behaviors and are often in control of organizing a family's opportunities to be active.

Examining individual, interpersonal, and environmental influences on children's physical activity levels.

The purpose of this study was to explore individual-level socio-demographic factors and interpersonal-level factors related to social support, as well as the potential role of neighborhood and school environments that may influence the physical activity (PA) levels of children (ages 9-11). Child and parent questionnaires included individual and interpersonal factors, and PA behaviour. Home postal codes were used to determine the neighbourhood the child resides within, as well as their geographic accessibility to recreation opportunities.

Exploring the effect of parental influence on children's physical activity: The mediating role of children's perceptions of parental support.

The purpose of this study was to test a conceptual model linking parental support and parental physical activity (PA), with children's perception of parental support and children's PA. Baseline data were drawn from the Grade 5 ACT-i-Pass community-based PA intervention conducted in London, Ontario between May and October 2014. Parent and child PA were measured using the International Physical Activity Questionnaire and Physical Activity Questionnaire for Children, respectively.

Are Indigenous Determinants of Health Associated with Self-Reported Health Professional-Diagnosed Anxiety Disorders Among Canadian First Nations Adults?: Findings from the 2012 Aboriginal Peoples Survey.

We estimated the prevalence of self-reported health professional-diagnosed anxiety disorders among Canadian First Nations adults living off-reserve, and assessed the relationship between anxiety disorders and Indigenous determinants of health (Status Indian, residential school attendance, knowledge of Indigenous language, and participation in traditional activities) using the 2012 Aboriginal Peoples Survey. Multivariable logistic regression models were performed using bootstrap weights. The prevalence of anxiety disorders was 14.

Comparing physical activity and sedentary time among overweight and nonoverweight preschoolers enrolled in early learning programs: a cross-sectional study.

Establishing appropriate physical activity and sedentary behaviours during early childhood is important to ensure children accrue the many associated health benefits. While physical activity levels have been reported as low within early learning programs, little research has explored the physical activity and sedentary time of Canadian preschoolers classified as overweight within these facilities. The purpose of this study was to compare objectively measured physical activity and sedentary time among preschoolers classified as overweight and nonoverweight in early learning programs.
