Abstract: Objective Homelessness is a serious social and public health concern in Canada. Individuals experiencing homelessness face numerous health problems and barriers in accessing health services. Visual impairment can exacerbate the lower quality of life experienced by people who are homeless, but its incidence among this population has been poorly documented in the literature. Our study aimed to describe health and sociodemographic characteristics and determine their association with visual impairment, ocular pathology and uncorrected refractive errors in a homeless population in Montreal, Canada. Methods This cross-sectional study was conducted between May 2019 and September 2020 in eight homeless shelters selected using a stratified random sampling approach on the island of Montreal. An eye examination was performed on all participants, who were also administered a survey on social determinants of health. Descriptive analysis was used to analyze survey data, and logistic regression was used for each of the three study outcomes. Results A total of 124 individuals experiencing homelessness (93 men, 31 women) were recruited. Participants were mostly Caucasian (> 70%) with an average age of 48 years (standard deviation = 13 years). Our sample reported a high level of education (68% had a high school diploma or higher), a high level of health insurance coverage (77%), social assistance benefits (71%), and social support (over 50%). There was a high prevalence of chronic conditions including diabetes (14%), hypertension (25%), and HIV/AIDS (3%). Results from eye examinations showed a high prevalence of visual impairment (22%), ocular pathology (23%), and uncorrected refractive error (75%). Age was statistically significantly associated with each outcome variable. Conclusion Despite a high level of social and health support, individuals experiencing homelessness in Montreal, Canada, experience high levels of chronic conditions and visual impairment. Our study highlights the unmet need for eye healthcare among homeless populations, and that eye health can be a unique entry point for intervening with homeless populations. PubDate: 2023-02-01

Abstract: Objective This study examined the associations between public health engagement (PHE) in school-based substance use prevention programs and student substance use. For the purposes of this study, PHE refers to any form of collaboration between the local government public health agency and the school to promote the physical and mental health of students. Methods Data for this study were collected from the Cannabis, Obesity, Mental health, Physical activity, Alcohol use, Smoking and Sedentary behaviour (COMPASS) study during the 2018/2019 data collection year. Multilevel logistic regression was used to analyze the associations between PHE and student substance use. Results Data from 84 schools and 42,149 students were included; 70% of schools had PHE in substance use prevention programs. PHE in substance use prevention appears to have had no significant impact on student substance use in our models. When PHE was divided into five methods of engagement, it was found that when public health solved problems jointly with schools, the odds of a student using alcohol or cannabis significantly increased. When schools were split into low- and high-use schools for each substance measured, some methods of PHE significantly decreased the odds of cannabis and cigarette use in high-use schools and significantly increased the odds of alcohol and cannabis use in low-use schools. Conclusion This study highlights the need to develop better partnerships and collaborations between public health and schools, and the importance of ensuring that school-based substance use prevention programs are evidence-based and tailored to the specific needs of schools and students.

Abstract: Objectives Vaccine hesitancy is a multifaceted decision process that encompasses various factors for which an individual may choose to get vaccinated or not. We aimed to identify the relationship between COVID-19 conspiracy theories, general attitudes towards vaccines, current COVID-19 vaccine factors, and COVID-19 vaccine hesitancy. Methods The present research is a multi-province cross-sectional study design. Survey data were collected in May and June 2021 (n=4905) in the Canadian provinces of Alberta, Ontario, and Quebec. Multivariate ordinal regression models were used to assess the association between vaccine hesitant profiles and COVID-19 conspiracy theories, general attitudes towards vaccines, and specific factors pertaining to COVID-19 vaccines. Results Participants were aged 18 to 40 years and 59% were women. Individuals with low income, with low educational attainment, and/or who are unemployed were more likely to be vaccine hesitant. COVID-19 conspiracy theory beliefs and general attitudes towards vaccines are significantly associated with greater hesitancy for the COVID-19 vaccine. Vaccine factors including pro-vaccine actions and opinions of friends and family and trust in scientists and government as well as the country in which a vaccine is manufactured are associated with less vaccine hesitancy. Conclusion Conspiracy theories are distinct from criticism and concerns regarding the vaccine. Nevertheless, poverty, low level of education, and distrust towards the government are associated with higher odds of being vaccine hesitant. Results suggest it is imperative to deliver transparent and nuanced health communications to address legitimate distrust towards political and scientific actors and address the societal gap regarding general attitudes towards vaccines as opposed to focusing solely on COVID-19.

Abstract: Objective Alcohol use is a known risk factor for suicidality, yet this relationship has not been explored during the pandemic in Canada. As a growing body of evidence demonstrates the negative impact of COVID-19 on alcohol consumption and associated harms in Canada, there is a need to examine this more closely. Methods Using the Survey on COVID-19 and Mental Health 2020, we compared the prevalence of suicide ideation among: (1) individuals who reported an increase in alcohol consumption vs those who reported a decrease/no change, and (2) individuals who reported past month heavy episodic drinking vs those who did not. We compared overall unadjusted odds ratios and across a number of sociodemographic and mental health variables. All estimates were weighted to ensure they were nationally representative. Results The prevalence and likelihood of suicide ideation were significantly higher among people who reported increased alcohol consumption during the pandemic (4.9% vs 2.0%; OR = 2.6, 95% CI: 1.8, 3.7) and people who reported past month heavy episodic drinking (3.4% vs 2.1%; OR = 1.7, 95% CI: 1.2, 2.3). Males and middle-aged and older-aged individuals had the highest odds ratios for increased alcohol consumption and past month heavy episodic drinking with suicide ideation. Conclusion In the Canadian general population during the COVID-19 pandemic, there were significant associations between suicide ideation and increased alcohol use as well as past month heavy episodic drinking across specific sociodemographic subgroups. Future research could explore these associations while adjusting for social determinants of health such as income security, employment, education, social support, stress, and mental health.

Abstract: Objectives Little is known about immunization coverage among kindergarten-aged children in jurisdictions that do not require children’s immunization records to be provided at school entry. Thus, we assessed immunization coverage and associated characteristics of a 2008 birth cohort of Alberta children at kindergarten entry as compared with at the end of grade one. Methods This retrospective cohort study used population-based administrative health data for childhood vaccines in Alberta, Canada. We categorized and compared immunization status of children as follows: (a) complete at kindergarten entry; (b) incomplete at kindergarten entry but complete at the end of grade one; and (c) still incomplete at the end of grade one. To assess factors associated with immunization status, we used multinomial logistic regression. Results Immunization coverage for the complete vaccine series for children (N = 41,515) at kindergarten entry was suboptimal (44.5%, 95% CI 44.0–45.0) and substantially lower than for children at the end of grade one (74.8%, 95% CI 74.3–75.2). Young maternal age, not living with a partner, and having > 1 child in a household were associated with incomplete immunization status at kindergarten entry. Midwife-assisted hospital and home delivery was strongly associated with incomplete immunization status at the end of grade one. Conclusion Immunization coverage at kindergarten entry was strikingly low. Risk factors for incomplete immunization status were identified that require particular attention when addressing immunization coverage. The school-based catch-up immunization program in grade one seems to have substantially improved coverage among children, suggesting a potential benefit of shifting the catch-up program from grade one to kindergarten entry.

Abstract: Setting Toronto (Ontario, Canada) is a large urban centre with a significant population of underhoused residents and several dozen shelters for this population with known medical and social vulnerabilities. A sizeable men’s homeless shelter piloted a facility-level SARS-CoV-2 wastewater surveillance program. Intervention Wastewater surveillance was initiated at the shelter in January 2021. One-hour composite wastewater samples were collected twice weekly from a terminal sanitary clean-out pipe. The genetic material of the SARS-CoV-2 virus was extracted from the solid phase of each sample and analyzed using real-time qPCR to estimate the viral level. Wastewater results were reported to facility managers and Toronto Public Health within 4 days. Outcomes There were 169 clients on-site at the time of the investigation. Wastewater surveillance alerted to the presence of COVID-19 activity at the site, prior to clinical detection. This notification acted as an early warning signal, which allowed for timely symptom screening and case finding for shelter managers and the local health unit, in preparation for the declaration of an outbreak. Implications Wastewater surveillance acted as an advanced notification leading to the timely deployment of enhanced testing prior to clinical presentation in a population with known vulnerabilities. Wastewater surveillance at the facility level is beneficial, particularly in high-risk congregate living settings such as shelters that house transient populations where clinical testing and vaccination can be challenging. Open communication, established individual facility response plans, and a balanced threshold for action are essential to an effective wastewater surveillance program. PubDate: 2023-02-01

Abstract: Objectives To describe the methodology and key findings of British Columbia’s (BC) COVID-19 SPEAK surveys, developed to understand the experiences, knowledge, and impact of the COVID-19 pandemic on British Columbians. Methods Two province-wide, cross-sectional, web-based population health surveys were conducted one year apart (May 2020 and April/May 2021). Questions were drawn from validated sources grounded within the social determinants of health to assess COVID-19 testing and prevention; mental and physical health; risk and protective factors; and healthcare, social, and economic impacts during the pandemic. Quota-based non-probability sampling by geography was applied to recruit a representative sample aged 18 years and older. Recruitment included strategic outreach and longitudinal follow-up of a subgroup of respondents from round one to round two. Post-collection weighting using Census data by age, sex, education, ethnicity, and geography was conducted. Results Participants included 394,382 and 188,561 British Columbians for the first and second surveys, respectively, including a longitudinal subgroup of 141,728. Key findings showed that societal impacts, both early in the pandemic and one year later, were inequitably distributed. Families with children, young adults, and people from lower socioeconomic backgrounds have been most impacted. Significant negative impacts on mental health and stress and a deterioration in protective resiliency factors were found. Conclusion These population health surveys consisting of two large cross-sectional samples provided valuable insight into the impacts and experiences of British Columbians early in the pandemic and one year later. Timely, actionable data informed several high-priority public health areas during BC’s response to the COVID-19 pandemic. PubDate: 2023-02-01

Abstract: Objective The objective of this study is to simultaneously assess the associations between suboptimal oral health (SOH) and cardiovascular disease (CVD) and competing death (CD). Methods Ontario residents aged 40 years and over who participated in the Canadian Community Health Survey 2003 and 2007–2008 were followed until December 31, 2016 for the incidence of CVD or CD. SOH was assessed based on self-rated oral health and inability to chew. Multivariable competing risk analysis was adjusted for socioeconomic characteristics, behavioural factors and intermediate health outcomes. Results The study sample included 36,176 participants. Over a median follow-up of 9.61 years, there were 2077 CVD events and 3180 CD events. The fully adjusted models indicate 35% (HR = 1.35, 95% CI: 1.12–1.64) increase in the risk of CVD and 57% (HR = 1.57, 95% CI: 1.33–1.85) increase in the risk of CD among those who reported poor oral health as compared to those who reported excellent oral health. The fully adjusted models also indicate 11% (HR = 1.11, 95% CI: 0.97–1.27) increase in the hazard of CVD and 37% (HR = 1.37, 95% CI: 1.24–1.52) increase in the hazard of CD among those who reported inability to chew. Conclusion This study provides important information to contextualize CVD risk among those with SOH. The competing risk analysis indicates that those with SOH may benefit from additional interventions to prevent CVD and CD. Accordingly, managing the risk of CVD among those with SOH should fall under a more comprehensive approach that aims at improving their overall health and well-being. PubDate: 2023-02-01

Abstract: Objective Breastfeeding difficulties are the most common reason for breastfeeding cessation, particularly in the early postpartum. Caesarean delivery is associated with earlier breastfeeding cessation than is the case with vaginal delivery, but differences in breastfeeding difficulties by mode of delivery have not been thoroughly examined. Our objective was to explore the association between Caesarean delivery and types of breastfeeding difficulties. Methods We conducted a secondary analysis of data from a prospective cohort study of mothers who delivered full-term, singleton infants in Calgary, Alberta, Canada (N = 418). Women completed self-report questionnaires during the delivery hospitalization. Mode of delivery was defined as vaginal or Caesarean, and further classified as planned or unplanned Caesarean. Breastfeeding difficulties were measured using the Breastfeeding Experiences Scale and operationalized with binary variables for presence of various types of maternal (i.e. physical, supply, social) and infant (i.e. latch, behaviour/health) difficulties that were reported as moderate to unbearable. Multivariable logistic regression was used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs). Results Overall, 37.1% of women had a Caesarean delivery and 80.9% experienced a breastfeeding difficulty during the delivery hospitalization. Of the difficulties studied, Caesarean delivery was significantly associated with low milk supply (AOR = 1.62, 95% CI = 1.16–2.28) and infant behaviour/health difficulties (AOR = 1.33, 95% CI = 1.01–1.75). The association with low milk supply persisted when examining both planned (AOR = 2.42, 95% CI = 1.19–4.92) and unplanned (AOR = 2.21, 95% CI = 1.16–4.22) Caesarean deliveries. Conclusion Mothers who deliver by Caesarean have higher odds of reporting low milk supply and infant behaviour/health difficulties than women who deliver vaginally. PubDate: 2023-02-01

Abstract: Objectives The COVID-19 pandemic has been associated with increased mental health problems. We investigated (1) associations between disordered eating in adolescence and mental health problems after one year of the pandemic and (2) the mechanisms explaining associations. Method We analyzed data from a population-based birth cohort in Quebec, Canada (557 males and 759 females). High and low levels of disordered eating symptom trajectories were previously estimated (age 12, 15, 17, and 20 years). Anxiety, depression, non-suicidal self-injury, and suicidal ideation were assessed at 23 years (March–June 2021). Putative mediators included loneliness and social media use (age 22 years, July–August 2020). Analyses controlled for mental health and socio-economic status at age 10–12 years and were conducted for males and females separately. Results Females in the high-level disordered eating symptom trajectory were at increased risk for non-suicidal self-injury (OR 1.60; 95% CI 1.02–2.52) and suicidal ideation (2.16; 1.31–3.57), whereas males were at increased risk for severe anxiety (2.49; CI 1.11–5.58). Males and females in the high-level trajectory were more likely to report severe depression (2.26; 1.14–5.92 and 2.15, 1.36–3.38 respectively). Among females, associations were partially explained (17–35%) by loneliness during the first 4 months of the pandemic. Conclusion Young adults who experienced disordered eating as adolescents were at increased risk of mental health problems during the pandemic. Loneliness partially mediated the effect, suggesting that pandemic mitigation resulting in increased social isolation may have exacerbated mental health problems among women with a history of disordered eating.
