Design and implementation of the Our Health Counts (OHC) methodology for First Nations, Inuit, and Metis (FNIM) health assessment and response in urban and related homelands.

OBJECTIVES: Methods for enumeration and population-based health assessment for First Nations, Inuit, and Metis (FNIM) living in Canadian cities are underdeveloped, with resultant gaps in essential demographic, health, and health service access information. Our Health Counts (OHC) was designed to engage FNIM peoples in urban centres in "by community, for community" population health assessment and response. METHODS: The OHC methodology was designed to advance Indigenous self-determination and FNIM data sovereignty in urban contexts through deliberate application of Indigenous principles and linked implementation strategies. Three interwoven principles (good relationships are foundational; research as gift exchange; and research as a vehicle for Indigenous community resurgence) provide the framework for linked implementation strategies which include actively building and maintaining relationships; meaningful Indigenous community guidance, leadership, and participation in all aspects of the project; transparent and equitable sharing of project resources and benefits; and technical innovations, including respondent-driven sampling, customized comprehensive health assessment surveys, and linkage to ICES data holdings to generate measures of health service use. RESULTS: OHC has succeeded across six urban areas in Ontario to advance Indigenous data sovereignty and health assessment capacity; recruit and engage large population-representative cohorts of FNIM living in urban and related homelands; customize comprehensive health surveys and data linkages; generate previously unavailable population-based FNIM demographic, health, and social information; and translate results into enhanced policy, programming, and practice. CONCLUSION: The OHC methodology has been demonstrated as effective, culturally relevant, and scalable across diverse Ontario cities.

RéSUMé: OBJECTIFS: Les méthodes de dénombrement et d'évaluation populationnelle de la santé des personnes des Premières Nations, des Inuits et des Métis (PNIM) vivant dans les villes du Canada sont sous-développées, ce qui laisse des lacunes dans les informations essentielles sur le profil démographique, la santé et l'accès aux services de santé. Le projet Notre santé compte (NSC) vise à collaborer avec les personnes des PNIM dans les centres urbains au moyen d'une évaluation de la santé des populations et d'une intervention « pour nous-mêmes, par nous-mêmes ¼. MéTHODE: La méthode NSC est conçue pour renforcer l'autodétermination autochtone et la souveraineté des données des PNIM vivant en milieu urbain par l'application délibérée de principes autochtones et de stratégies de mise en œuvre connexes. Trois principes imbriqués (« les bonnes relations sont fondamentales ¼; « la recherche en tant qu'échange de cadeaux ¼; et « la recherche comme vecteur de résurgence des communautés autochtones ¼) constituent le cadre de stratégies de mise en œuvre connexes : l'établissement et le maintien actifs de relations; la guidance, la participation et le leadership significatifs des communautés autochtones dans tous les aspects du projet; le partage transparent et équitable des ressources et des avantages du projet; et les innovations techniques, dont l'échantillonnage en fonction des répondants, les enquêtes de santé exhaustives et personnalisées, et les couplages avec les fonds de données de l'Institut de recherche en services de santé (ICES), pour produire des indicateurs d'utilisation des services de santé. RéSULTATS: L'approche NSC a réussi dans six agglomérations urbaines de l'Ontario : à renforcer la souveraineté des données et la capacité d'évaluation de la santé des populations autochtones; à recruter et à mobiliser de vastes cohortes représentatives des PNIM vivant en milieu urbain et sur les territoires connexes; à personnaliser des enquêtes de santé exhaustives et des couplages de données; à générer des informations démographiques, sanitaires et sociales non disponibles auparavant sur les populations des PNIM; et à traduire ces résultats en politiques, en programmes et en pratiques améliorés. CONCLUSION: Il est démontré que la méthode NSC est efficace, culturellement appropriée et modulable dans différentes villes de l'Ontario.

Randomized controlled trial demonstrates novel tools to assess patient outcomes of Indigenous cultural safety training.

BACKGROUND: Health care routinely fails Indigenous peoples and anti-Indigenous racism is common in clinical encounters. Clinical training programs aimed to enhance Indigenous cultural safety (ICS) rely on learner reported impact assessment even though clinician self-assessment is poorly correlated with observational or patient outcome reporting. We aimed to compare the clinical impacts of intensive and brief ICS training to control, and to assess the feasibility of ICS training evaluation tools, including unannounced Indigenous standardized patient (UISP) visits. METHOD: Using a prospective parallel group three-arm randomized controlled trial design and masked standardized patients, we compared the clinical impacts of the intensive interactive, professionally facilitated, 8- to10-h Sanyas ICS training; a brief 1-h anti-bias training adapted to address anti-Indigenous bias; and control continuing medical education time-attention matched to the intensive training. Participants included 58 non-Indigenous staff physicians, resident physicians and nurse practitioners from family practice clinics, and one emergency department across four teaching hospitals in Toronto, Canada. Main outcome measures were the quality of care provided during UISP visits including adjusted odds that clinician would be recommended by the UISP to a friend or family member; mean item scores on patient experience of care measure; and clinical practice guideline adherence for NSAID renewal and pain assessment. RESULTS: Clinicians in the intensive or brief ICS groups had higher adjusted odds of being highly recommended to friends and family by standardized patients (OR 6.88, 95% CI 1.17 to 40.45 and OR 7.78, 95% CI 1.05 to 58.03, respectively). Adjusted mean item patient experience scores were 46% (95% CI 12% to 80%) and 40% (95% CI 2% to 78%) higher for clinicians enrolled in the intensive and brief training programs, respectively, compared to control. Small sample size precluded detection of training impacts on clinical practice guideline adherence; 100% of UISP visits were undetected by participating clinicians. CONCLUSIONS: Patient-oriented evaluation design and tools including UISPs were demonstrated as feasible and effective. Results show potential impact of cultural safety training on patient recommendation of clinician and improved patient experience. A larger trial to further ascertain impact on clinical practice is needed. TRIAL REGISTRATION: Clinicaltrials.org NCT05890144. Retrospectively registered on June 5, 2023.

Our Health Counts: Examining associations between colonialism and ever being incarcerated among First Nations, Inuit, and Métis people in London, Thunder Bay, and Toronto, Canada.

OBJECTIVES: Indigenous peoples have a disproportionately high prevalence of incarceration in the Canadian justice system. However, there is limited Indigenous-driven research examining colonialism and the justice system, specifically associations between racism, externally imposed family disruptions, and history of ever being incarcerated. Therefore, this study examined the association between the proportion of previous incarceration and family disruption, experiences of racism, and victimization for Indigenous adults in London, Thunder Bay, and Toronto, Ontario, Canada. The three communities expressed that they did not want comparison between the communities; rather, they wanted analysis of their community to understand where more supports were needed. METHODS: Indigenous community partners used respondent-driven sampling (RDS) to collect data from First Nations, Inuit, and Métis (FNIM) peoples in London, Thunder Bay, and Toronto. Prevalence estimates, 95% confidence intervals, and relative risk were reported using unweighted Poisson models and RDS-adjusted proportions. RESULTS: Proportions of ever being incarcerated ranged from 43.0% in London to 54.0% in Toronto and 72.0% in Thunder Bay. In all three cities, history of child protection involvement and experiencing racism was associated with an approximate 25.0% increase in risk for previous incarceration. In Toronto and London, victimization was associated with increased risk for incarceration. CONCLUSION: This research highlights disproportionately high prevalence of ever being incarcerated among FNIM living in three Ontario cities. Experiencing racism, family disruption, and victimization are associated with incarceration. Decreasing the rates of family disruption, experiences of racism, and victimization should inform future policy and services to reduce the disproportionately high prevalence of incarceration for FNIM people living in urban settings.

RéSUMé: OBJECTIFS: Les personnes autochtones présentent une prévalence démesurément élevée d'incarcération dans le système judiciaire canadien. Il y a cependant peu d'études dirigées par des Autochtones sur le colonialisme et le système judiciaire, en particulier sur les associations entre le racisme, les perturbations familiales imposées de l'extérieur et les antécédents d'incarcération. C'est pourquoi nous avons fait porter notre étude sur l'association entre la proportion d'incarcérations antérieures et de perturbations familiales, les expériences de racisme et la victimisation chez les adultes autochtones vivant à London, Thunder Bay et Toronto (Ontario), au Canada. Les trois villes ont dit ne pas vouloir que nous fassions de comparaisons entre elles; elles voulaient plutôt des analyses de leur ville pour savoir où des mesures de soutien supplémentaires étaient nécessaires. MéTHODE: Des partenaires associatifs autochtones ont utilisé l'échantillonnage en fonction des répondants (EFR) pour collecter des données auprès des personnes des Premières Nations, des Inuits et des Métis (PNIM) à London, Thunder Bay et Toronto. Les estimations de prévalence, les intervalles de confiance de 95 % et le risque relatif ont été présentés à l'aide de modèles de Poisson non pondérés et de proportions ajustées selon l'EFR. RéSULTATS: La proportion de répondantes et de répondants ayant déjà été incarcérés était de 43 % à London, de 54 % à Toronto et de 72 % à Thunder Bay. Dans les trois villes, la fréquentation des services de protection de l'enfance et l'expérience du racisme étaient associées à une hausse d'environ 25 % du risque d'incarcération antérieure. À Toronto et à London, la victimisation était associée à un risque accru d'incarcération. CONCLUSION: Cette étude souligne la prévalence démesurément élevée de l'incarcération antérieure chez les personnes PNIM vivant dans trois villes de l'Ontario. L'expérience du racisme, les perturbations familiales et la victimisation étaient associées à l'incarcération. La réduction des taux de perturbations familiales, d'expérience du racisme et de victimisation devrait éclairer les politiques et les services futurs afin de réduire la prévalence démesurément élevée de l'incarcération chez les personnes PNIM vivant en milieu urbain.

The association between shift work exposure and cognitive impairment among middle-aged and older adults: Results from the Canadian Longitudinal Study on Aging (CLSA).

BACKGROUND: Shift work, especially rotating and night shift work, has been linked to a wide range of detrimental health outcomes. Occupational factors like shift work and their potential impact on cognitive functions have received little attention, and the evidence is inconclusive. The objective of our study is to explore associations between shift work exposure and cognitive impairment indicators based on comparisons with the normative standards from the Canadian population. METHODS: Cross-sectional analyses were performed using baseline Canadian Longitudinal Study on Aging database, including 47,811 middle-aged and older adults (45-85 years). Three derived shift work variables were utilized: ever exposed to shift work, shift work exposure in longest job, and shift work exposure in current job. Four cognitive function tests were utilized, Rey Auditory Verbal Learning Tests (immediate and delayed) representing memory domain, and Animal Fluency, and Mental Alteration, representing the executive function domain. All cognitive test scores included in study were normalized and adjusted for the participant's age, sex, education and language of test administration (English and French), which were then compared to normative data to create "cognitive impairment' variables. Unadjusted and adjusted multivariable logistic regression models were used to determine associations between shift work variables and cognitive impairment individually (memory and executive function domains), and also for overall cognitive impairment. RESULT: Overall, one in every five individuals (21%) reported having been exposed to some kind of shift work during their jobs. Exposure to night shift work (both current and longest job) was associated with overall cognitive impairment. In terms of domain-based measures, night shift work (longest job) was associated with memory function impairment, and those exposed to rotating shift work (both current and longest job) showed impairment on executive function measures, when compared to daytime workers. CONCLUSION: This study suggests disruption to the circadian rhythm, due to shift work has negative impact on cognitive function in middle-aged and older adults and this warrants further investigation.

Evaluation of Respondent-Driven Sampling Prevalence Estimators Using Real-World Reported Network Degree.

Respondent-driven sampling (RDS) is used to measure trait or disease prevalence in populations that are difficult to reach and often marginalized. The authors evaluated the performance of RDS estimators under varying conditions of trait prevalence, homophily, and relative activity. They used large simulated networks (N = 20,000) derived from real-world RDS degree reports and an empirical Facebook network (N = 22,470) to evaluate estimators of binary and categorical trait prevalence. Variability in prevalence estimates is higher when network degree is drawn from real-world samples than from the commonly assumed Poisson distribution, resulting in lower coverage rates. Newer estimators perform well when the sample is a substantive proportion of the population, but bias is present when the population size is unknown. The choice of preferred RDS estimator needs to be study specific, considering both statistical properties and knowledge of the population under study.

Relationships to land as a determinant of wellness for Indigenous women, two-spirit, trans, and gender diverse people of reproductive age in Toronto, Canada.

OBJECTIVE: Disparities in Indigenous reproductive health reflect Canada's historic and ongoing colonial relationship with Indigenous peoples, which includes persistent inequities in health and social services. Reproductive justice scholars and activists advocate for intersectional approaches to enhancing Indigenous health equity that recognize land as a central determinant of wellness. The purpose of this study is to examine the association between relationships to land and wellness in a study of urban Indigenous women, two-spirit, trans, and gender diverse people of reproductive age in Canada's largest city, Toronto. METHODS: Data were obtained from the cross-sectional Our Health Counts (OHC) Toronto study, which employed respondent-driven sampling methods (n = 323) and a community-directed comprehensive health assessment survey. In an exploratory analysis, we took an Indigenous reproductive justice theoretical approach to multivariable logistic regression. RESULTS: After adjusting for covariates, there was a statistically significant positive association between relationships to the land and wellness that was estimated with good precision (OR 3.7, 95% CI 2.5-5.3). CONCLUSION: Our findings indicate that among urban Indigenous women, two-spirit, trans, and gender diverse people of reproductive age there is a positive association between feeling strong in their relationships to land and feeling balanced in the four domains of health (physical, spiritual, mental, and emotional). The community-based, community-directed design of OHC Toronto was congruent with a reproductive justice approach to research. Reproductive justice theories are adaptable to quantitative research on Indigenous reproductive health and can yield novel insights for supporting Indigenous wellness.

RéSUMé: OBJECTIF: Les disparités que connaissent les peuples autochtones sur le plan de la santé reproductive sont le reflet des relations coloniales historiques et continues du Canada avec ces peuples, encore entachées d'iniquités dans les domaines de la santé et des services sociaux. Théoricien·nes et militant·es de la justice reproductive préconisent des approches intersectionnelles pour améliorer l'équité en santé chez les peuples autochtones, approches qui reconnaissent le territoire comme un déterminant central du bien-être. Nous avons voulu examiner l'association entre les relations avec le territoire et le bien-être dans une étude menée auprès de femmes et de personnes autochtones bispirituelles, trans et de diverses identités de genre en âge de procréer vivant à Toronto, la plus grande ville du Canada. MéTHODE: Nos données proviennent de l'étude transversale Our Health Counts (OHC) Toronto, qui a employé des méthodes d'échantillonnage en fonction des répondant·es (n = 323) et une enquête d'évaluation globale de la santé dirigée par la communauté. Dans une analyse exploratoire, nous avons employé la régression logistique multivariée selon une approche théorique de justice reproductive autochtone. RéSULTATS: Après l'apport d'ajustements pour tenir compte des covariables, nous avons observé une association positive significative entre les relations avec le territoire et le bien-être, que nous avons estimée avec une bonne précision (RC 3,7, IC de 95 % 2,5­5,3). CONCLUSION: D'après nos constatations, il y a chez les femmes et les personnes autochtones bispirituelles, trans et de diverses identités de genre en âge de procréer vivant en milieu urbain une association positive entre un fort sentiment d'appartenance au territoire et un sentiment d'équilibre entre les quatre domaines de la santé (physique, spirituel, mental et émotionnel). L'étude OHC Toronto ayant été conçue par et pour la communauté, elle est conforme à une approche de recherche axée sur la justice reproductive. Les théories de la justice reproductive peuvent être adaptées à la recherche quantitative sur la santé reproductive autochtone, et elles peuvent jeter un nouvel éclairage sur les moyens d'appuyer le bien-être des personnes autochtones.

Uncovering SARS-COV-2 vaccine uptake and COVID-19 impacts among First Nations, Inuit and Métis Peoples living in Toronto and London, Ontario.

BACKGROUND: First Nations, Inuit and Métis Peoples across geographies are at higher risk of SARS-CoV-2 infection and COVID-19 because of high rates of chronic disease, inadequate housing and barriers to accessing health services. Most Indigenous Peoples in Canada live in cities, where SARS-CoV-2 infection is concentrated. To address gaps in SARS-CoV-2 information for these urban populations, we partnered with Indigenous agencies and sought to generate rates of SARS-CoV-2 testing and vaccination, and incidence of infection for First Nations, Inuit and Métis living in 2 Ontario cities. METHODS: We drew on existing cohorts of First Nations, Inuit and Métis adults in Toronto (n = 723) and London (n = 364), Ontario, who were recruited using respondent-driven sampling. We linked to ICES SARS-CoV-2 databases and prospectively monitored rates of SARS-CoV-2 testing, diagnosis and vaccination for First Nations, Inuit and Métis, and comparator city and Ontario populations. RESULTS: We found that SARS-CoV-2 testing rates among First Nations, Inuit and Métis were higher in Toronto (54.7%, 95% confidence interval [CI] 48.1% to 61.3%) and similar in London (44.5%, 95% CI 36.0% to 53.1%) compared with local and provincial rates. We determined that cumulative incidence of SARS-CoV-2 infection was not significantly different among First Nations, Inuit and Métis in Toronto (7364/100 000, 95% CI 2882 to 11 847) or London (7707/100 000, 95% CI 2215 to 13 200) compared with city rates. We found that rates of vaccination among First Nations, Inuit and Métis in Toronto (58.2%, 95% CI 51.4% to 64.9%) and London (61.5%, 95% CI 52.9% to 70.0%) were lower than the rates for the 2 cities and Ontario. INTERPRETATION: Although Ontario government policies prioritized Indigenous populations for SARS-CoV-2 vaccination, vaccine uptake was lower than in the general population for First Nations, Inuit and Métis Peoples in Toronto and London. Ongoing access to culturally safe testing and vaccinations is urgently required to avoid disproportionate hospital admisson and mortality related to COVID-19 in these communities.

Modelling prevalent cardiovascular disease in an urban Indigenous population.

OBJECTIVE: Studies have highlighted the inequities between the Indigenous and non-Indigenous populations with respect to the burden of cardiovascular disease and prevalence of predisposing risks resulting from historical and ongoing impacts of colonization. The objective of this study was to investigate factors associated with cardiovascular disease (CVD) within and specific to the Indigenous peoples living in Toronto, Ontario, and to evaluate the reliability and validity of the resulting model in a similar population. METHODS: The Our Health Counts Toronto study measured the baseline health of Indigenous community members living in Toronto, Canada, using respondent-driven sampling. An iterative approach, valuing information from the literature, clinical insight and Indigenous lived experiences, as well as statistical measures was used to evaluate candidate predictors of CVD (self-reported experience of discrimination, ethnic identity, health conditions, income, education, age, gender and body size) prior to multivariable modelling. The resulting model was then validated using a distinct, geographically similar sample of Indigenous people living in Hamilton, Ontario, Canada. RESULTS: The multivariable model of risk factors associated with prevalent CVD included age, diabetes, hypertension, body mass index and exposure to discrimination. The combined presence of diabetes and hypertension was associated with a greater risk of CVD relative to those with either condition and was the strongest predictor of CVD. Those who reported previous experiences of discrimination were also more likely to have CVD. Further study is needed to determine the effect of body size on risk of CVD in the urban Indigenous population. The final model had good discriminative ability and adequate calibration when applied to the Hamilton sample. CONCLUSION: Our modelling identified hypertension, diabetes and exposure to discrimination as factors associated with cardiovascular disease. Discrimination is a modifiable exposure that must be addressed to improve cardiovascular health among Indigenous populations.

RéSUMé: OBJECTIF: Des études ont souligné les iniquités entre les populations autochtones et non autochtones en ce qui a trait au fardeau des maladies cardiovasculaires et à la prévalence des risques prédisposants qui résultent des impacts historiques et continus de la colonisation. Nous avons voulu étudier les facteurs associés aux maladies cardiovasculaires (MCV) au sein des populations autochtones vivant à Toronto (Ontario) et spécifiques à ces populations, puis évaluer la fiabilité et la validité du modèle ainsi obtenu dans une population semblable. MéTHODE: L'étude Our Health Counts Toronto a mesuré l'état de santé de départ de membres de communautés autochtones vivant à Toronto, au Canada, à l'aide d'un échantillonnage en fonction des répondants. Une approche itérative, valorisant à la fois les données d'études scientifiques, l'expérience clinique, le vécu de personnes autochtones et les mesures statistiques, a été employée pour évaluer les candidats prédicteurs des MCV (expérience autodéclarée de discrimination, identité ethnique, affections médicales, revenu, instruction, âge, genre et taille) avant la modélisation multivariée. Le modèle ainsi obtenu a ensuite été validé à l'aide d'un échantillon distinct, mais géographiquement similaire, de personnes autochtones vivant à Hamilton (Ontario), au Canada. RéSULTATS: Le modèle multivarié des facteurs de risque associés aux MCV prévalentes incluait l'âge, le diabète, l'hypertension artérielle, l'indice de masse corporelle et l'exposition à la discrimination. La présence combinée du diabète et de l'hypertension artérielle était associée à un risque accru de MCV comparativement à l'une ou l'autre de ces deux affections médicales; c'était aussi la plus forte variable prédictive des MCV. Les personnes ayant déclaré des expériences passées de discrimination étaient aussi plus susceptibles d'être atteintes de MCV. D'autres études sont nécessaires pour déterminer l'effet de la taille sur le risque de MCV dans la population autochtone urbaine. Le modèle final avait un bon pouvoir discriminant et une calibration adéquate lorsqu'il a été appliqué à l'échantillon de Hamilton. CONCLUSION: Notre modélisation a cerné l'hypertension artérielle, le diabète et l'exposition à la discrimination comme facteurs associés aux maladies cardiovasculaires. La discrimination est un risque modifiable qui doit être abordé pour améliorer la santé cardiovasculaire au sein des populations autochtones.

Population-Level Impact and Cost-effectiveness of Continuous Glucose Monitoring and Intermittently Scanned Continuous Glucose Monitoring Technologies for Adults With Type 1 Diabetes in Canada: A Modeling Study.

OBJECTIVE: Maintaining healthy glucose levels is critical for the management of type 1 diabetes (T1D), but the most efficacious and cost-effective approach (capillary self-monitoring of blood glucose [SMBG] or continuous [CGM] or intermittently scanned [isCGM] glucose monitoring) is not clear. We modeled the population-level impact of these three glucose monitoring systems on diabetes-related complications, mortality, and cost-effectiveness in adults with T1D in Canada. RESEARCH DESIGN AND METHODS: We used a Markov cost-effectiveness model based on nine complication states for adults aged 18-64 years with T1D. We performed the cost-effectiveness analysis from a single-payer health care system perspective over a 20-year horizon, assuming a willingness-to-pay threshold of CAD 50,000 per quality-adjusted life-year (QALY). Primary outcomes were the number of complications and deaths and the incremental cost-effectiveness ratio (ICER) of CGM and isCGM relative to SMBG. RESULTS: An initial cohort of 180,000 with baseline HbA1c of 8.1% was used to represent all Canadians aged 18-64 years with T1D. Universal SMBG use was associated with ∼11,200 people (6.2%) living without complications and ∼89,400 (49.7%) deaths after 20 years. Universal CGM use was associated with an additional ∼7,400 (4.1%) people living complications free and ∼11,500 (6.4%) fewer deaths compared with SMBG, while universal isCGM use was associated with ∼3,400 (1.9%) more people living complications free and ∼4,600 (2.6%) fewer deaths. Relative to SMBG, CGM and isCGM had ICERs of CAD 35,017/QALY and 17,488/QALY, respectively. CONCLUSIONS: Universal use of CGM or isCGM in the Canadian T1D population is anticipated to reduce diabetes-related complications and mortality at an acceptable cost-effectiveness threshold.

Precarious work among personal support workers in the Greater Toronto Area: a respondent-driven sampling study.

BACKGROUND: The COVID-19 pandemic has highlighted the role of personal support workers (PSWs) in health care, as well as their work conditions. Our study aimed to understand the characteristics of the PSW workforce, their work conditions and their job security, as well as to explore the health of PSWs and the impact of precarious employment on their health. METHODS: Our community-based participatory action research focused on PSWs in the Greater Toronto Area. We administered an online, cross-sectional survey between June and December 2020 using respondent-driven sampling. Data on sociodemographics, employment precarity, worker empowerment and health status were collected. We assessed the association between precarious employment and health using multivariable logistic regression models. RESULTS: We contacted 739 PSWs, and 664 consented to participate. Overall, 658 (99.1%) completed at least part of the survey. Using data adjusted for our sampling approach, the participants were predominantly Black (76.5%, 95% confidence interval [CI] 68.2%-84.9%), women (90.1%, 95% CI 85.1%-95.1%) and born outside of Canada (97.4%, 95% CI 94.9%-99.9%). Most worked in home care (43.9%, 95% CI 35.2%-52.5%) or long-term care (34.5%, 95% CI 27.4%-42.0%). Although most participants had at least some postsecondary education (unadjusted proportion = 83.4%, n = 529), more than half were considered low income (55.1%, 95% CI 46.3%-63.9%). Most participants were precariously employed (86.5%, 95% CI 80.7%-92.4%) and lacked paid sick days (89.5%, 95% CI 85.8%-93.3%) or extended health benefits (74.1%, 95% CI 66.8%-81.4%). Nearly half of the participants described their health as less than very good (46.7%, 95% CI 37.9%-55.5%). Employment precarity was significantly associated with higher risk of depression (odds ratio 1.02, 95% CI 1.01-1.03). INTERPRETATION: Despite being key members of health care teams, most PSWs were precariously employed with low wages that keep them in poverty; the poor work conditions they faced could be detrimental to their physical and mental health. Equitable strategies are needed to provide decent work conditions for PSWs and to improve their health.

The working conditions for personal support workers in the Greater Toronto Area during the COVID-19 pandemic: a mixed-methods study.

OBJECTIVE: During the height of the COVID-19 pandemic, personal support workers (PSWs) were heralded as healthcare 'heroes' as many of them cared for high-risk, vulnerable older populations, and worked in long-term care, which experienced a high number of COVID-19 outbreaks and deaths. While essential to the healthcare workforce, there is little understanding of PSW working conditions during the pandemic. The aim of our study was to examine the working conditions (including job security, work policies, and personal experiences) for PSWs in the Greater Toronto Area during the COVID-19 pandemic from the perspectives of PSWs. METHODS: This study used a mixed-methods design. From June to December 2020, we conducted a survey of 634 PSWs to understand their working conditions during the COVID-19 pandemic. Semi-structured interviews with 31 survey respondents were conducted from February to May 2021 to understand in greater depth how working conditions were impacting the well-being of PSWs. RESULTS: We found PSWs faced a range of challenges related to COVID-19, including anxiety about contracting COVID-19, reduced work hours, taking leaves of absences, concerns about job security, and losing childcare. While the COVID-19 pandemic highlighted the PSW workforce and their importance to the healthcare system (especially in the long-term care system), pre-existing poor work conditions of insecure jobs with no paid sick days and benefits exacerbated COVID-19-related challenges. Despite these hardships, PSWs were able to rely on their mental resilience and passion for their profession to cope with challenges. CONCLUSION: Significant changes need to be made to improve PSW working conditions. Better compensation, increased job security, decreased workload burden, and mental health supports are needed.

RéSUMé: OBJECTIF: Au plus fort de la pandémie de COVID-19, les préposés aux bénéficiaires (PAB) étaient salués comme les « héros ¼ des soins de santé, car beaucoup s'occupaient de populations vulnérables et âgées à risque élevé et travaillaient dans le milieu des soins de longue durée, qui était aux prises avec un grand nombre d'éclosions de COVID-19 et de décès. Malgré l'importance névralgique des PAB dans la main-d'œuvre des soins de santé, leurs conditions de travail durant la pandémie sont peu connues. Nous avons cherché à examiner les conditions de travail (sécurité d'emploi, régimes de travail et expériences personnelles) des PAB dans la région du Grand Toronto durant la pandémie de COVID-19 selon la perspective de ces PAB. MéTHODE: Nous avons utilisé un plan d'étude à méthodes mixtes. De juin à décembre 2020, nous avons sondé 634 PAB pour connaître leurs conditions de travail durant la pandémie de COVID-19. Des entretiens semi-directifs ont été menés auprès de 31 répondants et répondantes entre les mois de février et de mai 2021 pour approfondir notre compréhension de l'impact des conditions de travail des PAB sur leur bien-être. RéSULTATS: Nous avons constaté que les PAB ont connu de nombreuses difficultés en lien avec la COVID-19, dont l'anxiété à l'idée de transmettre la COVID-19, les heures de travail réduites, la prise de congés, les craintes pour leur sécurité d'emploi et la perte de services de garde. Bien que la pandémie de COVID-19 ait braqué les projecteurs sur les PAB et leur importance pour le système de soins de santé (surtout dans le système de soins de longue durée), leurs mauvaises conditions de travail préexistantes ­ des emplois précaires sans congés de maladie payés ni avantages sociaux ­ ont exacerbé les problèmes posés par la COVID-19. Malgré ces épreuves, les PAB ont pu compter sur leur résilience mentale et leur passion pour la profession pour faire face aux difficultés. CONCLUSION: D'importants changements doivent être apportés pour améliorer les conditions de travail des PAB. De meilleurs salaires, une plus grande sécurité d'emploi, une charge de travail allégée et des mesures d'appui à la santé mentale sont nécessaires.

The association between shift work exposure and the variations in age at natural menopause among adult Canadian workers: results from the Canadian Longitudinal Study on Aging (CLSA).

OBJECTIVE: A wide range of negative health outcomes have been associated with shift work (SW) particularly night and rotating SW. However, little is known about effects of SW exposure on reproductive health outcomes. The objective of our study is to prospectively investigate the association between SW exposure and the variations in age at natural menopause among adult Canadian workers. METHODS: Secondary data analyses were performed using the Canadian Longitudinal Study on Aging database. Premenopausal women (N = 3,688) at baseline were followed prospectively for 3 years. Three derived variables were used to measure SW primary exposure: 1) ever exposed to SW, 2) SW exposure in current job, and 3) SW exposure in the longest job. Cox proportional hazard regression models were used to evaluate risk of variations in age at natural menopause after adjusting for potential confounders. RESULT: One out of five women (20%) reported to be ever exposed to SW during their jobs. Overall, women who were ever exposed to SW were significantly associated with a delayed onset of menopause compared with daytime workers (hazard ratios [HR] = 0.77, 95% CI, 0.61-0.98). Particularly, when compared with daytime workers, rotating shift worker in the current and longest job were significantly related to delayed onset of menopause (HR = 0.64, 95% CI, 0.46-0.89 and HR = 0.65, 95% CI, 0.49-0.86), respectively. CONCLUSION: Our results suggest a relationship between rotating shift and delayed onset of menopause. We speculate that disruptive circadian stimuli may play a role in menopausal onset and this warrants further investigation.Video Summary:http://links.lww.com/MENO/A940 .

A Comparison of On-Ice External Load Measures Between Subelite and Elite Female Ice Hockey Players.

ABSTRACT: Douglas, AS, Rotondi, MA, Baker, J, Jamnik, VK, and Macpherson, AK. A comparison of on-ice external load measures between subelite and elite female ice hockey players. J Strength Cond Res 36(7): 1978-1983, 2022-This study quantified and examined differences in measures of on-ice external load for subelite and elite female ice hockey players. External load variables were collected from subelite (N = 21) and elite (N = 24) athletes using Catapult S5 monitors during the preseason. A total of 574 data files were analyzed from training and competition during the training camp. Significant differences between groups were found across all variables. Differences in training between the 2 groups ranged from trivial (forwards PlayerLoad, p = 0.03, effect-size [ES] = 0.18) to large (forwards Explosive Efforts [EEs], p < 0.001, ES = 1.64; defense EEs, p < 0.001, ES = 1.40). Match comparisons yielded similar results, with differences ranging from small (defense Low Skating Load [SL], p = 0.05, ES = 0.49; Medium SL, p = 0.04, ES = 0.52) to very large (forwards PlayerLoad, p < 0.001. ES = 2.25; PlayerLoad·min-1, p < 0.001, ES = 2.66; EEs, p < 0.001, ES = 2.03; Medium SL, p < 0.001, ES = 2.31; SL·min-1, p < 0.001, ES = 2.67), respectively. The differences in external load measures of intensity demonstrate the need to alter training programs of subelite ice athletes to ensure they can meet the demands of elite ice hockey. As athletes advance along the development pathway, considerable focus of their off-ice training should be to improve qualities that enhance their ability to perform high-intensity on-ice movements.

The Associations between Blood and Urinary Concentrations of Metal Metabolites, Obesity, Hypertension, Type 2 Diabetes, and Dyslipidemia among US Adults: NHANES 1999-2016.

Background: Heavy metals are well known to be associated with cancer outcomes, but its association with obesity and cardiometabolic risk outcomes requires further study. Methods: Adult data from the National Health and Examination Survey (NHANES Continuous 1999-2016, n = 12,636 to 32,012) with data for blood or urinary metals concentrations and body mass index were used. The study aim was twofold: (1) to determine the association between heavy metals and obesity and (2) to examine the influence of heavy metals on the relationship between obesity and hypertension, type 2 diabetes, and dyslipidemia. Logistic regression was used to examine the main effects and interaction effects of metals and obesity for the odds of prevalent hypertension, type 2 diabetes, and dyslipidemia. Models were adjusted for age, gender, ethnicity, smoking status, physical active status, and poverty-income ratio, with additional adjustment for creatinine in models with the urinary measures of heavy metals. High-low concentration categories were defined by grouping metal quintiles with the most similar associations with obesity. Results: Blood lead had a negative linear association with obesity (odds ratio (OR) = 0.42, 95% confidence interval (CI) = 0.37-0.47). In those with obesity, high blood lead was associated with lower risk of prevalent dyslipidemia, while no association was found in those without obesity. The study observed a curvilinear relationship between urinary antimony and obesity with the moderate group having the highest odds of obesity (OR = 1.36, 1.16-1.59). However, the relationship between urinary antimony and prevalent hypertension and dyslipidemia risk was linear, positive, and independent of obesity. While not associated with prevalent obesity risk, high urinary uranium was associated with 30% (P=0.01) higher odds for prevalent type 2 diabetes. Conclusions: The impact of environmental factors on obesity and health may be complex, and this study reinforces the heterogeneous relationship between various metals, obesity, and obesity-related metabolic diseases even at levels observed in the general population.

A systematic review and meta-analysis of the effect of treadmill desks on energy expenditure, sitting time and cardiometabolic health in adults.

BACKGROUND: As the health risks of sedentary working environments become more clear, greater emphasis on the implementation of walking interventions to reduce sitting time is needed. In this systematic review and meta-analysis, we investigate the role of treadmill-desk interventions on energy expenditure, sitting time, and cardiometabolic health in adults with sedentary occupations. METHODS: Relevant studies published in English were identified using CINAHL, EMBASE, MEDLINE, Web of Science, Scopus, and PubMed databases up to December 2020. Random effects meta-analysis models were used to pool study results. RESULTS: Thirteen relevant studies (six workplaces and seven laboratories) were found with a total of 351 participants. Pooled analysis of laboratory studies showed a significant increase in energy expenditure (105.23 kcal per hour, 95% confidence interval [CI]: 90.41 to 120.4), as well as metabolic rate (5.0 mL/kg/min, 95% CI: 3.35 to 6.64), among treadmill desk users compared to sitting conditions. No evidence of significant differences in blood pressure were found. In workplace studies, we observed a significant reduction in sitting time over a 24-h period (- 1.73 min per hour, 95% CI: - 3.3 to - 0.17) among users of treadmill desks, compared to a conventional desk. However, there were no evidence of statistically significant changes in other metabolic outcomes. CONCLUSIONS: Treadmill desks offer a feasible and effective intervention to increase energy expenditure and metabolic rate and reduce sitting time while performing work-related tasks. Future studies are needed to increase generalizability to different workplace settings and further evaluate their impact on cardiometabolic health.

The Efficacy of eHealth Interventions for the Treatment of Adults Diagnosed With Full or Subthreshold Binge Eating Disorder: Systematic Review and Meta-analysis.

BACKGROUND: There has been a recent rise in the use of eHealth treatments for a variety of psychological disorders, including eating disorders. OBJECTIVE: This meta-analysis of randomized controlled trials is the first to evaluate the efficacy of eHealth interventions specifically for the treatment of binge eating disorder (characterized by compulsive overconsumption of food, in a relatively short period, and without compensatory behaviors such as purging or fasting). METHODS: A search on the electronic databases PubMed, Web of Science, Embase, MEDLINE, and CINAHL was conducted for randomized controlled trials that compared the efficacy of eHealth treatment interventions with waitlist controls. RESULTS: From the databases searched, 3 studies (298 participants in total) met the inclusion criteria. All interventions were forms of internet-based guided cognitive behavioral therapy. The results of the analysis demonstrated that when compared with waitlist controls, individuals enrolled in eHealth interventions experienced a reduction in objective binge episodes (standardized mean difference [SMD] -0.77, 95% CI -1.38 to -0.16) and eating disorder psychopathology (SMD -0.71, 95% CI -1.20 to -0.22), which included shape (SMD -0.61, 95% CI -1.01 to -0.22) and weight concerns (SMD -0.91, 95% CI -1.33 to -0.48). There was no significant difference in BMI between the eHealth interventions and controls (SMD -0.01, 95% CI -0.40 to 0.39). CONCLUSIONS: These findings provide promising results for the use of internet-based cognitive behavioral therapy for binge eating disorder treatment and support the need for future research to explore the efficacy of these eHealth interventions.

A review of reported network degree and recruitment characteristics in respondent driven sampling implications for applied researchers and methodologists.

OBJECTIVE: Respondent driven sampling (RDS) is an important tool for measuring disease prevalence in populations with no sampling frame. We aim to describe key properties of these samples to guide those using this method and to inform methodological research. METHODS: In 2019, authors who published respondent driven sampling studies were contacted with a request to share reported degree and network information. Of 59 author groups identified, 15 (25%) agreed to share data, representing 53 distinct study samples containing 36,547 participants across 12 countries and several target populations including migrants, sex workers and men who have sex with men. Distribution of reported network degree was described for each sample and characteristics of recruitment chains, and their relationship to coupons, were reported. RESULTS: Reported network degree is severely skewed and is best represented by a log normal distribution. For participants connected to more than 15 other people, reported degree is imprecise and frequently rounded to the nearest five or ten. Our results indicate that many samples contain highly connected individuals, who may be connected to at least 1000 other people. CONCLUSION: Because very large reported degrees are common; we caution against treating these reports as outliers. The imprecise and skewed distribution of the reported degree should be incorporated into future RDS methodological studies to better capture real-world performance. Previous results indicating poor performance of regression estimators using RDS weights may be widely generalizable. Fewer recruitment coupons may be associated with longer recruitment chains.

Unmet health needs and discrimination by healthcare providers among an Indigenous population in Toronto, Canada.

OBJECTIVES: Inequalities between Indigenous and non-Indigenous peoples in Canada persist. Despite the growth of Indigenous populations in urban settings, information on their health is scarce. The objective of this study is to assess the association between experience of discrimination by healthcare providers and having unmet health needs within the Indigenous population of Toronto. METHODS: The Our Health Counts Toronto (OHCT) database was generated using respondent-driven sampling (RDS) to recruit 917 self-identified Indigenous adults within Toronto for a comprehensive health assessment survey. This cross-sectional study draws on information from 836 OHCT participants with responses to all study variables. Odds ratios and 95% confidence intervals were estimated to examine the relationship between lifetime experience of discrimination by a healthcare provider and having an unmet health need in the 12 months prior to the study. Stratified analysis was conducted to understand how information on access to primary care and socio-demographic factors influenced this relationship. RESULTS: The RDS-adjusted prevalence of discrimination by a healthcare provider was 28.5% (95% CI 20.4-36.5) and of unmet health needs was 27.3% (95% CI 19.1-35.5). Discrimination by a healthcare provider was positively associated with unmet health needs (OR 3.1, 95% CI 1.3-7.3). CONCLUSION: This analysis provides new evidence linking discrimination in healthcare settings to disparities in healthcare access among urban Indigenous people, reinforcing existing recommendations regarding Indigenous cultural safety training for healthcare providers. Our study further demonstrates Our Health Counts methodologies, which employ robust community partnerships and RDS to address gaps in health information for urban Indigenous populations.

More comprehensive reporting of methods in studies using respondent driven sampling is required: a systematic review of the uptake of the STROBE-RDS guidelines.

BACKGROUND: Respondent-driven sampling (RDS) is an increasingly popular method of recruiting participants from hard-to-reach populations and has traditionally been used to estimate the prevalence of HIV among marginalized people. The STROBE-RDS guidelines were published in 2015 to improve the reporting of these studies. We aim to determine the current applications of RDS and the quality of reporting of these studies. METHODS: The SCOPUS, PubMed, and CINAHL databases were used to find papers published in 2017, relating to RDS. Papers meeting the inclusion criteria of cross-sectional studies using RDS were classified according to the study outcome and target population. A random sample of 25 papers was selected to evaluate the quality of reporting using the STROBE-RDS guidelines. RESULTS: Men who have sex with men, people who inject drugs, and female sex workers were the most common populations for RDS studies; over half of the studies examined the HIV epidemic. Quality of reporting is good with respect to the original STROBE guidelines but is generally weaker with respect to RDS-specific aspects of the study, including recruitment and statistical analysis. CONCLUSION: Most authors are using RDS appropriately and aware of the need for statistical adjustments to RDS data. Nonetheless, the STROBE-RDS guidelines should be more widely disseminated to promote better reporting of key aspects of RDS studies.
