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

Introduction: We analyzed the bio-food industry's corporate political activity (CPA) during the revisions of Canada's food guide between 2016 and 2019.

Methods: We undertook a content analysis of the websites of 11 bio-food industry organizations and of the briefs that 10 of them submitted to the Canadian House of Commons Standing Committee on Health, as part of this Committee's review of the food guide. Data were classified according to an existing conceptual framework.

Results: We identified 366 examples of CPA used by the bio-food industry during and immediately after the development of the food guide. Most of the industry actors opposed the guide's recommendations. The most common CPA strategies were information management (n = 197), used to create and disseminate information in industry's favour, and discursive strategies (n = 108), used to defend food products and promote the industry's position regarding the food guide. Influencing public policy (n = 40), by gaining indirect access to policy makers (e.g. through lobbying) and becoming active in government decision-making, as well as coalition management (n = 21), by establishing relationships with opinion leaders and health organizations, were also common strategies.

Conclusion: Bio-food industry actors used many different CPA strategies during the revisions of the food guide. It is important to continue to document the bio-food industry's CPA to understand whether and how this is shaping public policy development in Canada and elsewhere.

Introduction: Young adult drinking is a public health priority, but knowledge of socioeconomic status (SES) indicators and alcohol use among emerging adults (EAs; aged 18-29 years) is primarily informed by college samples, populations in their late teens and early twenties and non-Canadian data. We compared the association of three different SES indicators with monthly heavy episodic drinking (HED), less-than-monthly HED, no HED, and no drinking among Canadian EAs.

Methods: We pooled the 2015 to 2019 waves of the Canadian Community Health Survey to include participants aged 18 to 29 years (n = 29 598). Using multinomial regression, we calculated weighted estimates of alcohol use by education, household income and area-level disadvantage, adjusting for adult roles and sociodemographic characteristics.

Results: Approximately 30% of EAs engaged in monthly HED, whereas 16% did not drink at all in the past year. Compared to those in the lowest household incomes, being in the top income quintile was significantly associated with increased relative odds of monthly HED (e.g. in combined SES model, RRR = 1.21, 95% CI: 1.04-1.39). Higher levels of education, being in higher income quintiles and living in less disadvantaged areas were significantly associated with reduced relative odds of no HED and not drinking. Adjusting for adult roles did not substantially change the associations between SES and alcohol use.

Conclusion: Higher SES was associated with HED among EAs, although the magnitude of association was small. Universal prevention measures addressing the affordability, availability and marketing of alcohol could be complemented by interventions targeting EA populations at higher risk of HED.

Introduction: Previous research has suggested that how physicians are paid may affect the completeness of billing claims for estimating chronic disease. The purpose of this study is to estimate the completeness of physician billings for diabetes case ascertainment.

Methods: We used administrative data from eight Canadian provinces covering the period 1 April 2014 to 31 March 2016. The patient cohort was stratified into two mutually exclusive groups based on their physician remuneration type: fee-for-service (FFS), for those paid only on that basis; and non-fee-for-service (NFFS). Using diabetes prescription drug data as our reference data source, we evaluated whether completeness of disease case ascertainment varied with payment type. Diabetes incidence rates were then adjusted for completeness of ascertainment.

Results: The cohort comprised 86 110 patients. Overall, equal proportions received their diabetes medications from FFS and NFFS physicians. Overall, physician payment method had little impact upon the percentage of missed diabetes cases (FFS, 14.8%; NFFS, 12.2%). However, the difference in missed cases between FFS and NFFS varied widely by province, ranging from -1.0% in Nova Scotia to 29.9% in Newfoundland and Labrador. The difference between the observed and adjusted disease incidence rates also varied by province, ranging from 22% in Prince Edward Island to 4% in Nova Scotia.

Conclusion: The difference in the loss of cases by physician remuneration method varied across jurisdictions. This loss may contribute to an underestimation of disease incidence. The method we used could be applied to other chronic diseases for which drug therapy could serve as reference data source.

Introduction: First responders and other public safety personnel (PSP; e.g. correctional workers, firefighters, paramedics, police, public safety communicators) are often exposed to events that have the potential to be psychologically traumatizing. Such exposures may contribute to poor mental health outcomes and a greater need to seek mental health care. However, a theoretically driven, structured qualitative study of barriers and facilitators of help-seeking behaviours has not yet been undertaken in this population. This study used the Theoretical Domains Framework (TDF) to identify and better understand critical barriers and facilitators of help-seeking and accessing mental health care for a planned First Responder Operational Stress Injury (OSI) clinic.

Methods: We conducted face-to-face, one-on-one semistructured interviews with 24 first responders (11 firefighters, five paramedics, and eight police officers), recruited using purposive and snowball sampling. Interviews were analyzed using deductive content analysis. The TDF guided study design, interview content, data collection, and analysis.

Results: The most reported barriers included concerns regarding confidentiality, lack of trust, cultural competency of clinicians, lack of clarity about the availability and accessibility of services, and stigma within first responder organizations. Key themes influencing help-seeking were classified into six of the TDF's 14 theoretical domains: environmental context and resources; knowledge; social influences; social/professional role and identity; emotion; and beliefs about consequences.

Conclusion: The results identified key actions that can be utilized to tailor interventions to encourage attendance at a First Responder OSI Clinic. Such approaches include providing transparency around confidentiality, policies to ensure greater cultural competency in all clinic staff, and clear descriptions of how to access care; routinely involving families; and addressing stigma.

Introduction: Respiratory therapists (RTs) faced morally distressing situations throughout the COVID-19 pandemic, including working with limited resources and facilitating video calls for families of dying patients. Moral distress is associated with a host of adverse psychological and functional outcomes (e.g. depression, anxiety, symptoms of posttraumatic stress disorder [PTSD] and functional impairment) and consideration of position departure. The purpose of this study was to understand the impact of moral distress and its associated psychological and functional outcomes on consideration to leave a clinical position among Canadian RTs during the COVID-19 pandemic.

Methods: Canadian RTs (N = 213) completed an online survey between February and June 2021. Basic demographic information (e.g. age, sex, gender) and psychometrically validated measures of moral distress, depression, anxiety, stress, PTSD, dissociation, functional impairment, resilience and adverse childhood experiences were collected.

Results: One in four RTs reported considering leaving their position. RTs considering leaving reported elevated levels of moral distress and adverse psychological and functional outcomes compared to RTs not considering leaving. Over half (54.5%) of those considering leaving scored above the cut-off for potential diagnosis of PTSD. Previous consideration to leave a position and having left a position in the past each significantly increased the odds of currently considering leaving, along with system-related moral distress and symptoms of PTSD, but the contribution of these latter factors was small.

Conclusions: Canadian RTs considering leaving their position reported elevated levels of distress and adverse psychological and functional outcomes, yet these individual-level factors appear unlikely to be the primary factors underlying RTs' consideration to leave, because their effects were small. Further research is required to identify broader, organizational factors that may contribute to consideration of position departure among Canadian RTs.

Introduction: Airport firefighters are responsible for providing emergency responses to aviation incidents on a runway or in the vicinity of an airport, including airplane crashes, mass casualty events, emergency landings and many other concerns on airport grounds. While data exist on the occupational stressors of firefighters and public safety personnel in general, there is a gap in knowledge regarding the experiences of airport firefighters, particularly in relation to their organizational stressors, peer supports and attitudes toward mental health treatment.

Methods: We conducted two focus groups with 10 career firefighters working at an airport in Atlantic Canada in 2019. Focus groups were recorded; the recordings were transcribed and later coded using thematic analysis, which took an inductive, iterative, narrative approach.

Results: Airport firefighters face unique challenges, and operational stressors are overshadowed by organizational stressors. Additionally, peer support is an integral aspect of coping with both organizational stressors and critical incidents. Firefighters were found to have positive attitudes toward mental health treatment in general, but several barriers still remain, such as stigma, fear of being placed on leave and fear of confidentiality breach.

Conclusions: Specialized treatment options for public safety personnel and airport firefighters who engage in serious incidents outside of their regular duties are needed.

Introduction: Posttraumatic stress disorder (PTSD) can induce an elevation in sympathetic tone; however, research pertaining to the cardiac cycle in patients with PTSD is limited.

Methods: A literature review was conducted with PubMed, MEDLINE and Web of Science. Articles discussing changes and associations in echocardiography and PTSD or related symptoms were synthesized for the current review. We have also included data from a case report of a male participant aged 33 years experiencing potentially psychologically traumatic events, who wore a noninvasive cardiac sensor to assess the timing intervals and contractility parameters of the cardiac cycle using seismocardiography. The intervals included systolic time, isovolumic contraction time (IVCT) and isovolumic relaxation time (IVRT). Calculations of systolic (IVCT/systole), diastolic (IVRT/systole) and myocardial [(IVCT+IVRT)/systole] performance indices were completed.

Results: The review identified 55 articles, 14 of which assessed cardiac function using echocardiography in patients with PTSD symptoms. Cardiac dysfunction varied across studies, with diastolic and systolic impairments found in patients with PTSD. Our case study showed that occupational stress elevated cardiac performance indices, suggesting increased ventricular stress and supporting results in the existing literature.

Conclusions: The literature review results suggest that a controlled approach to assessing cardiac function in patients with PTSD is required. The case study results further suggest that acute bouts of stress can alter cardiac function, with potential for sustained occupational stress to induce changes in cardiac function. Cardiac monitoring can be used prospectively to identify changes induced by potentially psychologically traumatic event exposures that can lead to the development of PTSD symptoms.
