Sleep Efficiency and Sleep Onset Latency in One Saskatchewan First Nation.

BACKGROUND: Sleep efficiency and sleep onset latency are two measures that can be used to assess sleep quality. Factors that are related to sleep quality include age, sex, sociodemographic factors, and physical and mental health status. This study examines factors related to sleep efficiency and sleep onset latency in one First Nation in Saskatchewan, Canada. METHODS: A baseline survey of the First Nations Sleep Health project was completed between 2018 and 2019 in collaboration with two Cree First Nations. One-night actigraphy evaluations were completed within one of the two First Nations. Objective actigraphy evaluations included sleep efficiency and sleep onset latency. A total of 167 individuals participated, and of these, 156 observations were available for analysis. Statistical analysis was conducted using logistic and linear regression models. RESULTS: More females (61%) than males participated in the actigraphy study, with the mean age being higher for females (39.6 years) than males (35.0 years). The mean sleep efficiency was 83.38%, and the mean sleep onset latency was 20.74 (SD = 27.25) minutes. Age, chronic pain, ever having high blood pressure, and smoking inside the house were associated with an increased risk of poor sleep efficiency in the multiple logistic regression model. Age, chronic pain, ever having anxiety, heart-related illness, and smoking inside the house were associated with longer sleep onset latency in the multiple linear regression model. CONCLUSIONS: Sleep efficiency and sleep onset latency were associated with physical and environmental factors in this First Nation.

Ensuring Indigenous co-leadership in health research: a Can-SOLVE CKD case example.

BACKGROUND: Indigenous people are insightful and informed about their own health and wellness, yet their visions, strengths and knowledge are rarely incorporated into health research. This can lead to subpar engagement or irrelevant research practices, which exacerbates the existing health inequities Indigenous people experience compared to the non-Indigenous population. Data consistently underscores the importance of Indigenous self-determination in research as a means to address health inequities. However, there are few formal methods to support this goal within the existing research context, which is dominated by Western perspectives. MAIN TEXT: Canadians Seeking Solutions and Innovations to Overcome Chronic Kidney Disease (Can-SOLVE CKD) is a patient-oriented research network in Canada that recognizes the need to create the space to facilitate Indigenous self-determination in research. Indigenous members of the network therefore created and evolved a unique group, called the Indigenous Peoples' Engagement and Research Council (IPERC). IPERC plays a critical role in informing Can-SOLVE CKD research priorities, as well as creating tools to support Indigenous-specific research and engagement. This approach ensures that Indigenous voices and knowledge are critical threads within the fabric of the network's operations and research projects. Here, we describe the methods taken to create a council such as IPERC, and provide examples of initiatives by the council that aim to increase Indigenous representation, participation and partnership in research. We share lessons learned on what factors contribute to the success of IPERC, which could be valuable for other organizations interested in creating Indigenous-led research councils. CONCLUSION: Indigenous self-determination in research is critical for addressing health inequities. Here, we present a unique model, led by a council of diverse Indigenous people, which could help reduce health equities and lead to a better era of research for everyone.

Youth-onset type 2 diabetes mellitus: an urgent challenge.

The incidence and prevalence of youth-onset type 2 diabetes mellitus (T2DM) and its complications are increasing worldwide. Youth-onset T2DM has been reported in all racial and ethnic groups, but Indigenous peoples and people of colour are disproportionately affected. People with youth-onset T2DM often have a more aggressive clinical course than those with adult-onset T2DM or those with type 1 diabetes mellitus. Moreover, the available treatment options for children and adolescents with T2DM are more limited than for adult patients. Intermediate complications of youth-onset T2DM, such as increased albuminuria, often develop in late childhood or early adulthood, and end-stage complications, including kidney failure, develop in mid-life. The increasing frequency, earlier onset and greater severity of childhood obesity in the past 50 years together with increasingly sedentary lifestyles and an increasing frequency of intrauterine exposure to diabetes are important drivers of the epidemic of youth-onset T2DM. The particularly high risk of the disease in historically disadvantaged populations suggests an important contribution of social and environmental factors, including limited access to high-quality health care, healthy food choices and opportunities for physical activity as well as exposure to stressors including systemic racism and environmental pollutants. Understanding the mechanisms that underlie the development and aggressive clinical course of youth-onset T2DM is key to identifying successful prevention and management strategies.

STOP-Bang Score and Prediction of Severity of Obstructive Sleep Apnea in a First Nation Community in Saskatchewan, Canada.

The STOP-Bang questionnaire is an easy-to-administer scoring model to screen and identify patients at high risk of obstructive sleep apnea (OSA). However, its diagnostic utility has never been tested with First Nation peoples. The objective was to determine the predictive parameters and the utility of the STOP-Bang questionnaire as an OSA screening tool in a First Nation community in Saskatchewan. The baseline survey of the First Nations Sleep Health Project (FNSHP) was completed between 2018 and 2019. Of the available 233 sleep apnea tests, 215 participants completed the STOP-Bang score questionnaire. A proportional odds ordinal logistic regression analysis was conducted using the total score of the STOP-Bang as the independent variable with equal weight given to each response. Predicted probabilities for each score at cut-off points of the Apnea Hypopnea Index (AHI) were calculated and plotted. To assess the performance of the STOP-Bang questionnaire, sensitivity, specificity, positive predictive values (PPVs), negative predictive values (NPVs), and area under the curve (AUC) were calculated. These data suggest that a STOP-Bang score ≥ 5 will allow healthcare professionals to identify individuals with an increased probability of moderate-to-severe OSA, with high specificity (93.7%) and NPV (91.8%). For the STOP-Bang score cut-off ≥ 3, the sensitivity was 53.1% for all OSA and 72.0% for moderate-to-severe OSA. For the STOP-Bang score cut-off ≥ 3, the specificity was 68.4% for all OSA and 62.6% for moderate-to-severe OSA. The STOP-Bang score was modestly superior to the symptom of loud snoring, or loud snoring plus obesity in this population. Analysis by sex suggested that a STOP-Bang score ≥ 5 was able to identify individuals with increased probability of moderate-to-severe OSA, for males with acceptable diagnostic test accuracy for detecting participants with OSA, but there was no diagnostic test accuracy for females.

Obesity, Sex, Snoring and Severity of OSA in a First Nation Community in Saskatchewan, Canada.

Sleep disorders have been related to body weight, social conditions, and a number of comorbidities. These include high blood pressure and type 2 diabetes, both of which are prevalent in the First Nations communities. We explored relationships between obstructive sleep apnea (OSA) and risk factors including social, environmental, and individual circumstances. An interviewer-administered survey was conducted with adult participants in 2018−2019 in a First Nations community in Saskatchewan, Canada. The survey collected information on demographic variables, individual and contextual determinants of sleep health, and objective clinical measurements. The presence of OSA was defined as an apnea−hypopnea index (AHI) ≥5. Multiple ordinal logistic regression analysis was conducted to examine relationships between the severity of OSA and potential risk factors. In addition to the survey, 233 men and women participated in a Level 3 one-night home sleep test. Of those, 105 (45.1%) participants were reported to have obstructive sleep apnea (AHI ≥ 5). Mild and moderately severe OSA (AHI ≥ 5 to <30) was present in 39.9% and severe OSA (AHI ≥ 30) was identified in 5.2% of participants. Being male, being obese, and snoring loudly were significantly associated with severity of OSA. The severity of OSA in one First Nation appears relatively common and may be related to mainly individual factors such as loud snoring, obesity, and sex.

Duration and quality of sleep in 2 rural Cree First Nation communities in Saskatchewan, Canada.

STUDY OBJECTIVES: Estimates of sleep duration and quality are lacking for Canadian First Nations peoples. This study examines the prevalence of and risk factors for short/normal/long sleep duration and sleep quality. METHODS: Five hundred eighty-eight adults participated in the baseline survey of the First Nations Sleep Health Project conducted in 2018-2019 in Saskatchewan, Canada. Sleep duration and quality were self-reported. RESULTS: Mean sleep duration was 8.18 hours per night. About 45.5% slept the recommended 7 hours per night. However, short sleep duration and poor sleep quality were relatively common: about one-quarter of the participants slept fewer hours than recommended. Sleep duration was significantly less for men than women. Women were significantly more likely to report poor sleep quality than males. Multiple regression models revealed that age was significantly related with shorter sleep duration; sex and employment status were significantly related with sleep duration; and sex and income indicators were significantly associated with sleep quality. Nearly half of participants reported having had the recommended hours of sleep, but nearly two-thirds reported poor sleep quality. CONCLUSIONS: Information about the proportion of First Nations adults who sleep the recommended duration and the quality of sleep is important in informing health care and health policy.

Seasonal Changes in Sleep Patterns in Two Saskatchewan First Nation Communities.

Sleep is crucial for maintaining the recovery and restoration of the body and brain. Less sleep is associated with poor mental and physical performance. Seasonal changes in sleep patterns can be observed. This paper examines seasonal effects on sleep timing, duration, and problems in two Cree First Nation communities in Saskatchewan, Canada. Data were available from a community survey of 588 adults aged 18 years and older (range: 18-78 years) with 44.2% males and 55.8% females. Results are presented using descriptive statistics and a binary logistic-regression model to identify the association between seasonal changes in sleep patterns, and demographic, social, and environmental factors. The participants reported sleeping the least during the spring and summer months and sleeping the most during the fall and winter months. This was further confirmed by sleep hours and the lower proportion of recommended hours of sleep during the spring and summer, and a higher proportion of longer sleep duration during the fall and winter months. There was no significant variation in sleeping onset and wake-up times by season. Overall, there were no significant differences in the prevalence of sleep deprivation, insomnia, and excessive daytime sleepiness by season. When stratified by age group and sex, some differences existed in the prevalence of sleep problems by season. More than two-thirds (68.6%) of the participants reported that there was a change in sleep patterns across seasons, and about 26.0% reported a very or extremely marked change in sleep patterns across seasons. Changes in sleep patterns by season were related to money left at the end of the month and damage caused by dampness in the house.

Highly Elevated Prevalence of Spinobulbar Muscular Atrophy in Indigenous Communities in Canada Due to a Founder Effect.

OBJECTIVE: Spinobulbar muscular atrophy (SBMA) is an X-linked adult-onset neuromuscular disorder that causes progressive weakness and androgen insensitivity in hemizygous males. This condition is reported to be extremely rare, but has higher prevalence in certain populations due to multiple founder effects. Anecdotal observations of a higher prevalence of SBMA in patients of Indigenous descent in Saskatchewan led us to perform this study, to estimate the disease prevalence, and to attempt to identify a founder effect. METHODS: For our prevalence estimation, we identified patients with confirmed SBMA diagnosis from the Saskatoon neuromuscular clinic database for comparison with population data available from Statistics Canada. For our haplotype analysis, participants with SBMA were recruited from 2 neuromuscular clinics, as well as 5 control participants. Clinical data were collected, as well as a DNA sample using saliva kits. We performed targeted quantification of DXS1194, DXS1111, DXS135, and DXS1125 microsatellite repeats and the AR GGC repeat to attempt to identify a disease haplotype and compare it with prior studies. RESULTS: We estimate the prevalence of SBMA among persons of Indigenous descent in Saskatchewan as 14.7 per 100,000 population. Although we believe that this is an underestimate, this still appears to be the highest population prevalence for SBMA in the world. A total of 21 participants were recruited for the haplotype study, and we identified a unique haplotype that was shared among 13 participants with Indigenous ancestry. A second shared haplotype was identified in 2 participants, which may represent a second founder haplotype, but this would need to be confirmed with future studies. CONCLUSIONS: We describe a very high prevalence of SBMA in western Canadians of Indigenous descent, which appears to predominantly be due to a founder effect. This necessitates further studies of SBMA in these populations to comprehensively ascertain the disease prevalence and allow appropriate allocation of resources to support individuals living with this chronic disease.

Sleep deprivation in two Saskatchewan First Nation communities: a public health consideration.

OBJECTIVES: Sleep deprivation is a common problem in Canada and is associated with many health problems. More than a quarter of Canadians get fewer than the recommended sleep hours (<7 h). This paper examines the prevalence and risk factors for sleep deprivation in two First Nation communities in Saskatchewan, Canada. METHODS: The baseline cross-sectional survey was completed between 2018 and 2019 in collaboration with the two Cree First Nation communities in Saskatchewan, Canada. There were five hundred and eighty-eight participants participated in the survey from two communities. A Multivariate logistic regression model was used for analysis. RESULTS: The prevalence of sleep deprivation (<7 h of sleep) was 25.4%. The multivariate logistics regression revealed that middle and older age groups, visible mold in the house, and being male with nighttime insomnia symptoms were significantly associated with a higher risk of sleep deprivation among study participants in the study. CONCLUSIONS: In these two First Nation communities, a higher proportion of the participants reported having sleep deprivation. This was a unique study, which evolved from ongoing research collaboration with two First Nation communities in Saskatchewan, Canada. Findings will be helpful in the management of patients with sleep deprivation in these communities; as well as for co-creating policy with the communities and future research priorities.

Wabishki Bizhiko Skaanj: a learning pathway to foster better Indigenous cultural competence in Canadian health research.

OBJECTIVE: In Canada, Indigenous people experience racism across diverse settings, including within the health sector. This has negatively impacted both the quality of care that Indigenous people receive as well as how research related to Indigenous populations is conducted. Therefore, an Indigenous-led council at a kidney research network, in partnership with other key stakeholders, sought to create a learning pathway that aims to distill the racism that Indigenous people face, and build cultural competence, within the health sector. PARTICIPANTS: The learning pathway was designed for researchers, health care providers, patient partners and administrators. SETTING: Various components of the pathway are established trainings in healthcare and research settings at provincial and national levels. Provincially, some components are implemented in British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. INTERVENTION: The pathway, called Wabishki Bizhiko Skaanj (meaning "White Horse" in Anishinaabemowin), involves six key steps: a culturally tailored blanket exercise that walks participants through the history of local Indigenous Nations/peoples; a more detailed online training program (San'yas); a series of webinars on Indigenous research ethics and protocols; an educational booklet about engaging Knowledge Keepers in research, as well as sharing details about their traditional knowledge and culture; two certification programs about Indigenous ownership of data; and a "book club," wherein the conversation of racism-and the goal for finding solutions-is continually discussed. OUTCOMES: Wabishki Bizhiko Skaanj is working to build cultural competence in the Canadian health sector. IMPLICATIONS: This learning pathway has the potential to address racial disparities across the country and improve health outcomes for Indigenous peoples.

RéSUMé: OBJECTIF: Au Canada, les autochtones font face au racisme dans divers milieux, y compris dans le secteur de la santé. Cela a eu une incidence négative sur la qualité des soins que reçoivent les peuples autochtones, ainsi que sur la façon dont la recherche sur les populations autochtones est menée. Par conséquent, un conseil dirigé par des Autochtones dans un réseau de recherche sur les reins, en partenariat avec d'autres parties prenantes, a cherché à créer une voie d'apprentissage visant à réduire le racisme auquel les peuples autochtones sont confrontés et à renforcer les compétences culturelles au sein du secteur de la santé. PARTICIPANTS: La voie d'apprentissage a été conçue pour les chercheurs, les fournisseurs de soins de santé, les patients partenaires et les administrateurs. CADRE: Cette voie d'apprentissage est composée de formations établies dans le milieu de la santé et de la recherche au niveau provincial et national. À l'échelle provinciale, il y a des programmes ayant lieu en Colombie-Britannique, en Alberta, en Ontario, en Saskatchewan et au Manitoba. INTERVENTION: La voie d'apprentissage, appelée Wabishki Bizhiko Skaanj (qui signifie « cheval blanc ¼ en Anishinaabemowin), comporte six étapes clés : un exercice culturel sur mesure qui guide les participants à travers l'histoire des nations/peuples autochtones locaux à l'aide de diverses couvertures culturelles; un programme de formation en ligne détaillé (San'yas); une série de webinaires sur l'éthique et les protocoles autochtones en matière de recherche; un livret pédagogique sur l'engagement des gardiens de la connaissance en recherche ainsi que le partage d'informations sur leur connaissance et leur culture traditionnelle; deux programmes de certification sur la propriété autochtone des données; et un « club de lecture ¼ dans lequel nous ne cessons de discuter du racisme tout en cherchant des solutions. RéSULTATS: Wabishki Bizhiko Skaanj s'efforce de renforcer les compétences culturelles dans le secteur de la santé au Canada. IMPLICATIONS: Cette voie d'apprentissage a le potentiel de s'attaquer aux disparités raciales à l'échelle nationale et d'améliorer les résultats en matière de santé pour les peuples autochtones.

Prevalence of Insomnia in Two Saskatchewan First Nation Communities.

Insomnia is a common problem in Canada and has been associated with increased use of health care services and economic burden. This paper examines the prevalence and risk factors for insomnia in two Cree First Nation communities in Saskatchewan, Canada. Five hundred and eighty-eight adults participated in a baseline survey conducted as part of the First Nations Sleep Health Collaborative Project. The prevalence of insomnia was 19.2% among participants with an Insomnia Severity Index score of ≥15. Following the definition of nighttime insomnia symptoms, however, the prevalence of insomnia was much higher, at 32.6%. Multivariate logistic regression modeling revealed that age, physical health, depression diagnosis, chronic pain, prescription medication use for any health condition, and waking up during the night due to terrifying dreams, nightmares, or flashbacks related to traumatic events were risk factors for insomnia among participants from two Saskatchewan Cree First Nation communities.

A Framework to Ensure Patient Partners Have Equal and Contributing Voices Throughout the Research Program Evaluation Process.

PURPOSE OF PROGRAM: Traditionally, peer review was a closed process conducted only by individuals working in the research field. To establish a more integrated and patient-centered approach, one of Canada's largest kidney research networks (Can-SOLVE CKD) has created a Research Operations Committee (ROC) that includes patients as key members. The ROC represents one way for achieving meaningful patient-oriented research (POR). SOURCE OF INFORMATION: Can-SOLVE CKD, a network created as part of the Canadian Institutes of Health Research (CIHR) Strategy for Patient-Oriented Research (SPOR). METHODS: The ROC consists of patients, physicians, scientists, Indigenous partners, experts in research methodology, and a member of Can-SOLVE CKD's operational team. On an annual basis, Can-SOLVE CKD's research teams provide the ROC with a review package, which incorporates information from patient engagement check-in calls and surveys, the project's knowledge translation plan and products, and a progress report written by the project team. The ROC evaluates the review package and provides feedback and recommendations accordingly. KEY FINDINGS: The transparent nature of the process, regular feedback and review, along with an overt accountability and scoring system, has been embraced by both patients and researchers. As a result of the ROC process, the number of patient leads for each project has grown over a 3-year period and more researchers have received POR and cultural sensitivity training. LIMITATIONS: While anecdotal evidence suggests this approach is beneficial for achieving POR, formal mechanisms of evaluation are currently lacking. IMPLICATIONS: This ROC framework ensures patients are active contributors throughout the research process and could be adopted by other organizations to achieve a more patient-centered approach to research.

OBJECTIF DU PROGRAM: L'évaluation par les pairs consiste habituellement en un processus fermé et mené uniquement par des personnes travaillant dans le domaine de la recherche. Pour développer une approche plus intégrée et davantage axée sur les patients, un des plus importants réseaux canadiens de recherche sur les maladies rénales (Can-SOLVE CKD) a créé un comité de gestion de la recherche (CGR) où les patients sont des membres à part entière. Une approche qui vise la conduite d'activités de recherches significatives et davantage orientées vers le patient. SOURCE: Can-SOLVE CKD, un réseau créé dans le cadre de la Stratégie de recherche axée sur le patient (SRAP) des Instituts de recherche en santé du Canada (IRSC). MÉTHODOLOGIE: Le CGR rassemble des patients, des médecins, des chercheurs, des partenaires autochtones, des experts en méthodologie de recherche et un membre de l'équipe d'intervention de Can-SOLVE CKD. Une fois par année, l'équipe de recherche de Can-SOLVE CKD fournit au CGR un dossier d'examen. Ce dossier contient les informations recueillies lors d'appels ou de sondages vérifiant l'engagement des patients, le plan d'application des connaissances du projet et ses résultats, de même qu'un rapport périodique rédigé par l'équipe responsable du projet. Le CGR évalue ce dossier et émet ses commentaires et recommandations. PRINCIPAUX RÉSULTATS: La transparence du processus, la rétroaction et la révision sur une base régulière, de même que les systèmes de responsabilité et de notation ouverts ont été adoptés tant par les patients que par les chercheurs. Grâce à ce processus, le nombre de patients candidats pour chaque projet a augmenté sur une période de trois ans, et davantage de chercheurs ont reçu une formation sur les réalités culturelles et la pratique d'activités de recherche axées sur le patient. LIMITES: Bien que des preuves anecdotiques suggèrent que cette approche soit bénéfique à la conduite de recherches axées sur le patient, des mécanismes formels pour son évaluation manquent toujours. CONCLUSION: Le cadre proposé par le CGR assure une contribution active des patients tout au long du processus de recherche. Ce program pourrait être adopté par d'autres organizations et permettre la réalisation d'activités de recherche davantage axées sur le patient.

The Creation of a Tool to Measure Engagement in Patient-Oriented Research.

In 2017, the Saskatchewan Centre for Patient-Oriented Research (SCPOR) engaged patient and family advisors (PFAs) to review patient-oriented research grant proposals. The PFAs observed that the reviews would be less subjective if they were assessing the projects based on more rigorous criteria. Together the PFAs and SCPOR staff members developed a tool based on the Canadian Institutes of Health Research's Strategy for Patient-Oriented Research definition for patient-oriented research and the International Association for Public Participation's Spectrum of Public Participation. This article discusses the process of initiating a patient-identified project and co-creating the tool to indicate the level of patient-orientedness.
