A systematic review of theories, models and frameworks used for youth engagement in health research.

Background: Youth engagement in research, wherein youth are involved in the research beyond mere participation as human subjects, is growing and becoming more popular as an approach to research. However, systematic and deliberate theory-building has been limited. We conducted a systematic review to identify and synthesize theories, models and frameworks that have been applied in the engagement of youth in health research, including mental health.

E-Cigarette Dependence and Depressive Symptoms Among Youth.

Introduction: Although the relationship between smoking and depression has been well-established, little is known about the association between use of e-cigarette and depression, particularly among youth and young adults. This study proposes that e-cigarette dependence, rather than simply use, serves as a potential stressor and may interact with pre-existing vulnerabilities to contribute to depression in youth, consistent with the diathesis-stress theory. This study examines the longitudinal association of vaping dependence and vaping frequency on depression symptoms among youth and young adults who have never smoked cigarettes.

Co-Use, Simultaneous Use, and Mixing of Cannabis and Tobacco: A Cross-National Comparison of Canada and the US by Cannabis Administration Type.

Introduction: Increasing cannabis legalization raises concerns that the use of tobacco, frequently used with cannabis, will also increase. This study investigated the association between the legal status of cannabis in places of residence and the prevalence of cannabis and tobacco co-use, simultaneous use, and mixing by comparing the prevalence among adults in Canada (prior to cannabis legalization) vs. adults in US states that had legalized recreational cannabis vs.

Smoking, e-cigarettes and the effect on respiratory symptoms among a population sample of youth: Retrospective cohort study.

Introduction: E-cigarettes have been steadily increasing in popularity, both as cessation methods for smoking and for recreational and social reasons. This increase in vaping may pose cardiovascular and respiratory risks. We aimed to assess respiratory symptoms in youth users of e-cigarettes and cigarettes.

Prevalence and factors associated with self-reported exposure to secondhand cannabis smoke in the United States and Canada in 2019.

Little is known about exposure to secondhand cannabis smoke (SHCS) among residents of detached single-family homes and multiunit housing (MUH). Using data from the 2019 International Cannabis Policy Study, the prevalence of (a) self-reported exposure to SHCS at home (n = 33,024) and (b) self-reported SHCS incursions into MUH (defined as SHCS from another unit/the outdoors, n = 15,634) was estimated in (1) Canada; (2) US states where non-medical cannabis use was legal, and (3) US states where it remained illegal. Factors associated with exposures and incursions were assessed using weighted logistic regression.

Is vaping cessation like smoking cessation? A qualitative study exploring the responses of youth and young adults who vape e-cigarettes.

Introduction: Young people are now seeking help to quit vaping. However, little is known about vaping cessation. To bridge the gap between the current state of research and the urgent need for interventions, practitioners have drawn upon smoking cessation models under the assumption that vaping and smoking are fairly similar.

Co-use and Mixing Tobacco With Cannabis Among Ontario Adults.

Introduction: The legalization of nonmedical cannabis in 2018 may have important implications for tobacco use in Canada. There is a risk of renormalizing tobacco use with co-use of tobacco and cannabis introducing nontobacco users to tobacco. Co-use is the use of both substances by the same individual at the same time or on different occasions, as well as mixed together.

Prevalence of Involuntary Environmental Cannabis and Tobacco Smoke Exposure in Multi-Unit Housing.

No research has examined the prevalence of involuntary cannabis exposure in the home within the context of multi-unit housing (MUH). The 2017 cycle of the Centre for Addiction and Mental Health Monitor population RDD survey included measures of environmental cannabis smoke (ECS) and environmental tobacco smoke (ETS) for Ontario, Canada. These ECS measures were defined for those who did not live in a detached dwelling self-reporting noticing any tobacco or cannabis smoke enter the home from a neighboring unit or from outside the building at least once in the past 6 months.

Impact of smoke-free housing policy lease exemptions on compliance, enforcement and smoking behavior: A qualitative study.

This paper investigates the impacts of smoke-free housing policies on compliance, enforcement and smoking behavior. From 2012 to 2014, we studied two affordable housing providers in Canada with comprehensive smoke-free policies: Waterloo Regional Housing that required new leases to be non-smoking and exempted existing leases, and Yukon Housing Corporation that required all leases (existing and new) to be non-smoking. Focus groups and key informant interviews were conducted with 31 housing and public health staff involved in policy development and implementation, and qualitative interviews with 56 tenants.

Examining the role of urban street design in enhancing community engagement: A literature review.

Streets are an integral part of the built environment with the capacity to promote community engagement, as one aspect of health and well-being. However, there have been few attempts to synthesize published studies and interventions to gain a broader understanding of what street design features hinder or facilitate community engagement. Data was extracted from 30 eligible articles into 16 key topic areas or themes.

A Smoke-Free Community Housing Policy: Changes in Reported Smoking Behaviour-Findings from Waterloo Region, Canada.

In 2010, Waterloo Region Housing (Canada) enacted a smoke-free (SF) housing policy that made all new leases in their community-housing portfolio (2722 units) 100 % SF. Existing lease holders were 'grandfathered'-meaning tenants could still smoke in their homes. A survey to measure support for the policy and how the policy had impacted smoking behaviour was delivered to all 2722 households in the Waterloo Region Housing portfolio in 2010 (pre-policy), 2011 and 2013 (post-policy).

'Enter at your own risk': a multimethod study of air quality and biological measures in Canadian waterpipe cafes.

Background: Tobacco and non-tobacco-based waterpipe smoking has increased exponentially in many countries in recent decades, particularly among youth and young adults. Although tobacco smoking is banned in many indoor public places, waterpipe smoking, ostensibly non-tobacco, continues in Ontario and other jurisdictions where only tobacco smoking is prohibited. This study assessed air quality and exposure in waterpipe cafes using multiple methods and markers.

Not just 'a few wisps': real-time measurement of tobacco smoke at entrances to office buildings.

Introduction: An unintended consequence of indoor smoking restrictions is the relocation of smoking to building entrances, where non-smokers may be exposed to secondhand smoke, and smoke from outdoor areas may drift through entrances, exposing people inside. Tobacco smoke has been linked to numerous health effects in non-smokers and there is no safe level of secondhand smoke (SHS) exposure. This paper presents data on levels of tobacco smoke inside and outside entrances to office buildings.

Smoking in urban outdoor public places: Behaviour, experiences, and implications for public health.

This paper identifies factors that influence where people smoke outdoors and examines the impact of smoking on people who use outdoor public places. Direct observations of smoking at 12 outdoor public places and semi-structured interviews with 35 non-smoking and smoking adults were used to gather information in Toronto, Canada, about where people smoke, and smoking related behaviours, perspectives, and experiences. Observation and interview data show that smoking at building entrances was problematic.

Tobacco industry links to faculties of medicine in Canada.

Background: The tobacco industry uses various strategies to promote itself as a socially responsible, ethical industry, including establishing links with health institutions and medical research. The purpose of this study was to identify the relationships between the tobacco industry and Canadian faculties of medicine, specifically research funding and donations from tobacco industry sources, and faculty-specific policies regarding the acceptance of tobacco industry funds.

Methods: Information about policies and practices regarding research funding and donations from 1996-1999 was requested from the 16 Canadian faculties of medicine and their parent universities, as part of a larger cross-sectional survey-centred study that examined links between the tobacco industry and Canadian universities.
