Health Promotion and Chronic Disease Prevention in Canada-Research Policy and Practice最新文献

Introduction: Since 2004, the Children's Oral Health Initiative (COHI) has been working in many First Nations and Inuit communities in Canada to address oral health disparities, specifically early childhood caries (ECC). The COHI community-based approach improves early childhood oral health (ECOH) by balancing prevention with minimally invasive dentistry. The goal is to reduce the burden of oral disease, mainly by minimizing the need for surgery. We investigated program success in First Nations communities in the province of Manitoba, from the perspective of COHI staff.

Methods: First Nations community-based dental therapists and dental worker aides participated in three focus groups and an in-depth semistructured interview. The collected data were thematically analyzed.

Results: Data from 22 participants yielded converging and practitioner-specific themes. Participants reported that dental therapists and dental worker aides provide access to basic oral care in their communities including oral health assessments, teeth cleaning, fluoride varnish applications and sealants. The participants agreed that education, information sharing and culturally appropriate parental engagement are crucial for continuous support and capacity building in the community programs. Low enrolment, difficulty accessing homes and getting consent, limited human resources as well as lack of educational opportunities for dental worker aides were identified challenges.

Conclusion: Overall, the participants reported that the COHI program positively contributes to ECOH in First Nations communities. However, increased community-based training for dental workers, community awareness about the program, and engagement of parents to facilitate culturally appropriate programming and consent processes are critical to improving program outcomes.

Introduction: The Strengths and Difficulties Questionnaire (SDQ), for assessing behavioural and emotional difficulties, has been used internationally as a screening measure for mental health problems. Our objective was to validate the existing (British) SDQ cut-points in a sample of Canadian children and youth, and develop new Canadian SDQ cut-points if needed.

Methods: This study includes data from children and youth aged 6 to 17 years from the Canadian Health Measures Survey (n = 3435) and outpatient records from the Children's Hospital of Eastern Ontario (n = 1075). The parent-reported SDQ data were collected. We adjusted the existing SDQ cut-points using a distributional and receiver-operating characteristic (ROC) curve approach. We subsequently calculated the sensitivity, specificity and diagnostic odds ratio of the existing and new SDQ clinical cut-points to determine whether the new cut-points had better clinical utility, using both analytic approaches.

Results: Our data show differences in the screening effectiveness between the existing British and the Canadian-specific clinical cut-points. Specificity is maximized using the Canadian distributional cut-points, improving the likelihood of identifying true negative results. The total SDQ score met the threshold for clinical utility (diagnostic odds ratio > 20) using both the existing and new cut-points; however, the individual scales did not reach clinical utility threshold using either cut-points.

Conclusions: Future Canadian SDQ research should consider the new cut-points derived from our study population and the existing British cut-points to allow for historical and international comparisons.

Introduction: Despite the association between cannabis use and higher prevalence of suicidal ideation and attempt, the effect of cannabis legalization and regulation in Canada on intentional self-harm has not been determined.

Methods: We used an interrupted time series of population-based rates of emergency department (ED) visits and hospitalizations for intentional self-harm per 100 000 in Ontario and Alberta from January/April 2010 to February 2020. Aggregate monthly counts of ED visits and hospitalizations for intentional self-harm (ICD-10 codes X60-X84, R45.8) were obtained from the National Ambulatory Care Reporting System and Discharge Abstract Database, respectively.

Results: The legalization and regulation of cannabis in Canada was not significantly associated with a change in rates of ED visits for intentional self-harm in Ontario (level = 0.58, 95% CI: -1.14 to 2.31; trend = -0.17, 95% CI: -0.35 to 0.01) or Alberta (level = -0.06, 95% CI: -2.25 to 2.12; trend = -0.07, 95% CI: -0.27 to 0.13). Hospitalizations for intentional self-harm also remained unchanged in Ontario (level = -0.14, 95% CI: -0.48 to 0.20; trend = 0.01, 95% CI: -0.03 to 0.04) and Alberta (level = -0.41, 95% CI: -1.03 to 0.21; trend = -0.03, 95% CI: -0.08 to 0.03).

Conclusion: Legalization and regulation of cannabis in Canada has not increased rates of ED visits or hospitalizations for intentional self-harm in Ontario and Alberta. Individual-level analyses that account for demographic characteristics and include other provinces and territories are needed.

Introduction: There is evidence that some frontline and essential workers have increased their alcohol use during the COVID-19 pandemic; however, this has not been examined in Canada.

Methods: Using the Survey on COVID-19 and Mental Health 2020, weighted prevalence and 95% confidence intervals of self-reported increased alcohol consumption and heavy episodic drinking were calculated for each of the population groups: frontline workers, essential workers, and nonfrontline or essential workers (NFEW). Logistic regression was used to examine the associations between social determinants of health, mental health and alcohol use for each group.

Results: The prevalence of increased alcohol consumption and past-month heavy episodic drinking did not differ across frontline workers, essential workers and NFEW. For the three groups, nonracialized group members had significantly higher odds for both outcomes. Screening positive for either generalized anxiety disorder or mood disorder was significantly associated with increased alcohol consumption across the three groups. For frontline and essential workers, females had significantly lower odds of heavy episodic drinking compared to males. For essential workers only, living in a rural area was significantly associated with lower odds of increased alcohol use, and screening positive for posttraumatic stress disorder was significantly associated with increased odds of heavy episodic drinking. For frontline workers only, living in a rural area was significantly associated with lower odds of heavy episodic drinking.

Conclusion: While frontline and essential workers were not more likely to report increased alcohol consumption and heavy episodic drinking compared to NFEW, there were some differences in factors associated with alcohol use. Such findings demonstrate the benefit of examining each group separately to provide information for targeted prevention strategies.

News media are an underused source of localized information on complex and structural public health issues that are neglected in policy and unaccounted for in mainstream data collection. We applied systematic review search methods to online news media and developed a dataset highlighting municipal reactions and initiatives in response to public washroom pressures during the first year of the COVID-19 pandemic. Reliance on consumer-based models of washroom access "became news" amid the closures and lockdowns. Our results showed that many municipalities were grappling with the issue, but overwhelmingly responding with temporary and pandemic-specific measures that did not address the needs of marginalized groups.

Introduction: Anti-Black racism is a social determinant of health that has significantly impacted Black children and families. Limited research has examined anti-Black racism during the early years-a critical period of development. In this study, we sought to understand the manifestations of anti-Black racism in early childhood and explore its impact on Black children and families.

Methods: This qualitative research project was informed by critical race theory, Black Critical Theory and interpretive description. Early childhood educators (ECEs) and parents with Black children between the ages of 18 months and 5 years (n = 15) participated in virtual, semistructured interviews.

Results: Awareness of and protection against anti-Black racism was a constant in Black families' lives. Parents felt as though they had to remain hypervigilant and overprotective of their Black children, knowing they were liable to encounter racial violence. The early learning environment was a source of heightened stress for families, given the significant amount of time young children spend in child care. Black children were often "othered" in predominately White spaces and had been objectified by White ECE staff and children. Parents worked to instill a strong sense of self-confidence in their children to counteract the negative impacts of racial discrimination.

Conclusion: Results from this study suggest that children as young as 18 months are experiencing racial violence and adverse childhood experiences. Findings may contribute to antiracist policy development and a focus on more inclusive early childhood education for Black children and families.

Introduction: In Canada, people experiencing socioeconomic inequities have higher rates of late diagnosis and lower survival rates than the general population. Palliative care services focussed on this population are scarce. We developed a community-based nursing intervention to improve access to palliative care for people experiencing socioeconomic inequities and living with life-limiting illnesses in an urban Canadian setting.

Methods: This community-based, qualitative research study combined critical and participatory research methodologies. The study was conducted in partnership with the Palliative Care Outreach Advocacy Team (PCOAT) based in Edmonton, Alberta, a team dedicated to serving populations experiencing socioeconomic inequities who require palliative care. Following an exploratory phase that served to delineate the intervention, we undertook a one-year pilot implementation during which a part-time registered nurse (RN) joined PCOAT. The RN engaged in trust building, resolution of health and practical needs and complex care coordination. Twenty-five patients participated in the intervention. Participants were interviewed at least once to explore their experiences with the intervention. Data were analyzed through thematic analysis.

Results: Most participants were men, were Indigenous and had advanced cancer. Participants had significant financial concerns, lived or had lived in precarious housing situations and had previously faced serious challenges accessing health care. Participants reported social and health needs including housing, finances, transportation, symptom control, harm reduction and end-of-life care. Participants reported improved access to health and social services and expressed satisfaction with the study intervention.

Conclusion: Study findings suggest the study intervention may have contributed to improved access to palliative care, improved experiences for participants and increased equity in the delivery of care.
