Prioritizing determinants of cognitive function in healthy middle-aged and older adults: insights from a machine learning regression approach in the Canadian longitudinal study on aging.

The preservation of healthy cognitive function is a crucial step toward reducing the growing burden of cognitive decline and impairment. Our study aims to identify the characteristics of an individual that play the greatest roles in determining healthy cognitive function in mid to late life. Data on the characteristics of an individual that influence their health, also known as determinants of health, were extracted from the baseline cohort of the Canadian Longitudinal Study of Aging (2015). Cognitive function was a normalized latent construct score summarizing eight cognitive tests administered as a neuropsychological battery by CLSA staff. A higher cognitive function score indicated better functioning. A penalized regression model was used to select and order determinants based on their strength of association with cognitive function. Forty determinants (40) were entered into the model including demographic and socioeconomic factors, lifestyle and health behaviors, clinical measures, chronic diseases, mental health status, social support and the living environment. The study sample consisted mainly of White, married, men and women aged 45-64 years residing in urban Canada. Mean overall cognitive function score for the study sample was 99.5, with scores ranging from 36.6 to 169.2 (lowest to highest cognitive function). Thirty-five (35) determinants were retained in the final model as significantly associated with healthy cognitive functioning. The determinants demonstrating the strongest associations with healthy cognitive function, were race, immigrant status, nutritional risk, community belongingness, and satisfaction with life. The determinants demonstrating the weakest associations with healthy cognitive function, were physical activity, greenness and neighborhood deprivation. Greater prioritization and integration of demographic and socioeconomic factors and lifestyle and health behaviors, such greater access to healthy foods and enhancing aid programs for low-income and immigrant families, into future health interventions and policies can produce the greatest gains in preserving healthy cognitive function in mid to late life.

Mediation analysis of the associations between neighbourhood walkability and greenness, accelerometer-measured physical activity, and health-related fitness in urban dwelling Canadians

ObjectiveTo estimate sex-specific associations (total, direct, and indirect effects) between objectively measured neighbourhood walkability and greenness and objectively measured physical activity and health-related fitness including cardiorespiratory and muscular fitness in Canadian adults. MethodsNeighbourhood walkability (Canadian Active Living Environment) and greenness (Normalized Difference Vegetation Index; NDVI) data were linked to cardiorespiratory (i.e., submaximal step test estimated V̇O2 max) and muscular fitness (i.e., handgrip strength) and accelerometer measured physical activity; Canadian Health Measures Survey). Covariate-adjusted sex-stratified path analyses was conducted to assess if physical activity (light: LPA; moderate: MPA, and; vigorous: VPA) mediated the associations between neighbourhood walkability, NDVI and health-related fitness. Model sample sizes ranged from 987 to 2796 for males and 989 to 2835 for females. ResultsAmong males, we found indirect effects between neighbourhood walkability and cardiorespiratory fitness via LPA (negative) and VPA (positive). We also found a total effect (negative) between neighbourhood walkability and grip strength and indirect effects between neighbourhood walkability and handgrip strength via LPA (negative) and MPA (negative). Among females, we found a total effect (positive) and direct effect (positive) between neighbourhood walkability and cardiorespiratory fitness, and an indirect effect for neighbourhood walkability and cardiorespiratory fitness via LPA. We found no significant effects related to neighbourhood greenness. ConclusionsResiding in a neighbourhood with higher walkability may positively affect cardiorespiratory fitness but negatively affect muscular strength. The negative associations between neighbourhood walkability and LPA may offset potential positive associations between neighbourhood walkability and MPA and VPA and their subsequent influence on health-related fitness.

Effect of a relative pricing intervention and active merchandising on snack purchases: interrupted time series analysis of a hospital retailer-led strategy

BackgroundPricing policies have been shown to be an effective lever for promoting healthier dietary choices in consumer food environments. It is not yet well understood how pricing can be used to encourage healthier substitute purchases. The aim of the study was to assess the effect of a retailer-led relative pricing intervention on weekly purchases of targeted snack foods and beverages.MethodsThis was an ecological analysis in a real-world large tertiary hospital consumer food environment setting in urban Canada, comprised of four retail outlets: two large cafeterias, one smaller cafeteria, and one grab-and-go café. An interrupted time series analysis was designed to evaluate the effect of Snacking Made Simple, a retailer-led relative pricing intervention applied to 10 popular snack foods and beverages (n = 87 weeks, 66 weeks baseline and 21 weeks intervention, April 2018 to December 2019), on weekly purchase differences between healthier and less healthy targeted items, adjusted for weekly sales volume. Five healthier items were price discounted, alongside a price increase for five less healthy items. The intervention was actively merchandised in keeping with behaviour change theory.ResultsWeekly purchases of targeted snacks became healthier during the intervention period (β = 21.41, p = 0.0024). This followed a baseline period during which weekly purchases of less healthy targeted snacks had outpaced over time those of healthier targeted snacks (β = -11.02, p = 3.68E-14). We estimated that, all else being equal, a hypothetical 9.43 additional weeks of the intervention would be required to transition to net-healthier targeted snack purchases in this environment. The effects of the intervention varied by retail outlet, and the outcome appears driven by specific food items; further, examining merchandising implementation, we posited whether direct versus indirect substitution may have affected purchasing outcomes.ConclusionsRelative pricing may be a promising way to incentivize healthier substitute purchasing in the consumer food environment. Added attention to merchandising strategy as well as value-add factors within food categories and their effects on price salience may be an important factor in effective intervention design.

High Temperatures and Cardiovascular-Related Morbidity: A Scoping Review.

The primary objective of this review was to synthesize studies assessing the relationships between high temperatures and cardiovascular disease (CVD)-related hospital encounters (i.e., emergency department (ED) visits or hospitalizations) in urban Canada and other comparable populations, and to identify areas for future research. Ovid MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews, and Scopus were searched between 6 April and 11 April 2020, and on 21 March 2021, to identify articles examining the relationship between high temperatures and CVD-related hospital encounters. Studies involving patients with pre-existing CVD were also included. English language studies from North America and Europe were included. Twenty-two articles were included in the review. Studies reported an inconsistent association between high temperatures and ischemic heart disease (IHD), heart failure, dysrhythmia, and some cerebrovascular-related hospital encounters. There was consistent evidence that high temperatures may be associated with increased ED visits and hospitalizations related to total CVD, hyper/hypotension, acute myocardial infarction (AMI), and ischemic stroke. Age, sex, and gender appear to modify high temperature-CVD morbidity relationships. Two studies examined the influence of pre-existing CVD on the relationship between high temperatures and morbidity. Pre-existing heart failure, AMI, and total CVD did not appear to affect the relationship, while evidence was inconsistent for pre-existing hypertension. There is inconsistent evidence that high temperatures are associated with CVD-related hospital encounters. Continued research on this topic is needed, particularly in the Canadian context and with a focus on individuals with pre-existing CVD.

Clarifying rural-urban disparities in alcohol-related emergency department visits and hospitalizations in Ontario, Canada: A spatial analysis.

Rates of alcohol-related harm are higher in rural versus urban Canada. This study characterized the spatial distribution and regional determinants of alcohol-related emergency department (ED) visits and hospitalizations in Ontario to better understand this rural-urban disparity. This was a cross-sectional spatial analysis of rates of alcohol-related ED visits and hospitalizations by Ministry of Health subregion (n = 76) in Ontario, Canada between 2016 and 2019. Regional hot- and cold-spots of alcohol-related harm were identified using spatial autocorrelation methods. Rurality was measured as the population weighted geographic remoteness of a subregion. The associations between rurality and rates of alcohol-related ED visits and hospitalizations were evaluated using hierarchical Bayesian spatial regression models. Rates of alcohol-related ED visits and hospitalizations varied substantially between subregions, with high rates clustering in Northern Ontario. Overall, increasing rurality was associated with higher subregion-level rates of alcohol-related ED visits (males adjusted relative rate [aRR]: 1.67, 95% credible interval [CI]: 1.49-1.87; females aRR: 1.78, 95% CI: 1.60-1.98) and hospitalizations (males aRR: 1.34, 95% CI: 1.24-1.45; females aRR: 1.59, 95% CI: 1.45-1.74). However, after the province was separated into Northern and Southern strata, this association only held in Northern subregions. In contrast, increasing rurality was associated with lower rates of alcohol-related ED visits in Southern subregions (males aRR: 0.87, 95% CI: 0.79-0.96; females aRR: 0.88, 95% CI: 0.81-0.97). There are regional differences in the association between rurality and alcohol-related health service use. This regional variation should be considered when developing health policies to minimize geographic disparities in alcohol-related harm.

Preschoolers’ responses to prosocial opportunities during naturalistic interactions with peers: A cross‐cultural comparison

AbstractThe goal of this study was to better understand similarities and differences in preschool children's expression of needs and prosocial responsiveness to peers’ needs across two culturally distinct contexts. Preschoolers were observed in a semi‐naturalistic design across rural Mexico and urban Canada, wherein they were instructed to build a tower with blocks. Three‐ to 6‐year‐olds (N = 306; 48% female) were divided into 64 peer groups. We coded for children's expression of needs (instrumental, material, or emotional), responses to prosocial opportunities (prosociality, denial, or no response), prosociality without an apparent need (spontaneous prosociality), and types of prosocial behavior (helping, sharing, or comforting). While instrumental and material needs were expressed similarly across both samples, Tzotzil Maya children expressed fewer emotional needs than Canadian children. Failing to respond to others’ needs, followed by denial, were the most frequent need‐provoked response in both countries; surprisingly, only 9% of needs received a prosocial response. Though need‐provoked prosociality was rare in both cultural contexts, children engaged in considerable spontaneous prosociality which varied as a function of age, gender, and cultural context. Lastly, Canadian more than Tzotzil Maya children denied emotional and instrumental needs (but not material needs). The findings inform how cultural practices may shape the presentation of needs and prosocial responsiveness in peer interactions.

Performed worlding: Political praxis of Sikh nagar kirtan assemblies in Canada

Nagar kirtans are street assemblies with Sikh spiritual music, political marches, and free food distribution. They are especially large in April during the Punjabi harvest festival of Vaisakhi but also take place in other months. This paper explores the political praxis of nagar kirtans in Canada to contribute to critiques of secularism and theorize the political ontology in the Sikh context. I conceptualize nagar kirtan as a mobile court of both poetic pilgrimage and politics, which engage an embodied and performative world-making process, termed performed worlding, that is at odds with the modern ontology of the secular state. The empirical study analyzes early 20th century nagar kirtans in Vancouver and contemporary ones in urban Canada in the 2010-decade. Ethnographic fieldwork was carried out between 2017 and 2018 including analysis of interviews and archival and media content. Early nagar kirtans in Vancouver were aligned with the anti-colonial Ghadar Movement to protest the racial state of Canada. In the contemporary context, the study reveals competing ways of worlding the political ontologies of the mobile court. On the one hand, there is an increased commodification and state presence that refashions the practice at larger Vaisakhi nagar kirtan to be marketable to Canadian multiculturalism. On the other hand, the bottom-up assembling of participants align a spiritual politics of Sikh and Punjabi world-making, one that is grounded in practices of horizontal organizing and mutual care and sustain a form of embodied expression against racial Canada.

Relationships Between Migration and Microbiome Composition and Diversity in Urban Canada Geese

Microbiome analysis presents an opportunity to understand how urban environments affect avian physiology. For example, habitat use can affect microbiome diversity and composition, and hosts with more diverse gut microbiota are thought to be more resistant to pathogens and have increased fitness. However, the microbiome is an understudied aspect of avian ecology, particularly in the context of migration and urbanization in wild birds. For this study, we hypothesized that, within urban birds, migrants would exhibit greater microbial diversity and inter-individual variation in microbiome composition than residents because they are exposed to more diverse habitats. We focused on Canada geese (Branta canadensis), one of many migratory species that exhibit increasingly more year-round residency in cities. We used 16S rRNA gene amplicon sequencing to quantify microbiome taxonomic composition in fecal samples from 32 GPS-tracked Canada geese, 22 of which were year-round residents of the Chicago area and 10 of which were migrants. Similar to recent studies on wild species feeding near human habitation, urban resident geese had higher gut microbial diversity than migrants. They also had increased inter-individual variation in microbiome composition and, on average, lower relative abundances of bacteria in the phylum Firmicutes, and the genera Terrisporobacter, Turicibacter, and Cellulosilyticum, which all have metabolic functions that may aid in goose digestion. Therefore, the gut microbiome of resident geese may provide fewer potential health benefits. These patterns may be a result of anthropogenic influences on aspects of resident goose ecology, such as diet, as well the influence of migration on migrant goose ecology and biology. Overall, our results suggest that reduced migration for urban-adapted wildlife species may have important consequences for physiology and health.

Barriers to physical activity for adults in rural and urban Canada: A cross-sectional comparison

BackgroundIndividual differences in physical activity behavior are associated with a collection of individual and environmental factors manifesting as barriers to participation. Understanding how barriers to physical activity differ based on sociodemographic characteristics can support identification and elimination of health inequities. ObjectivesTo compare the odds of reporting individual and environmental barriers to physical activity in rural and urban adults, and explore interactions between rural-urban location and sociodemographic factors to characterize patterns in barriers to physical activity. DesignCross-sectional. MethodsWe analyzed the 2017 Canadian Community Health Survey Barriers to Physical Activity Rapid Response, with a final weighted sample of 24,499,462 (unweighted n=21,967). The likelihood of reporting each barrier domain based on rural-urban location was examined using binary logistic regression following a model-fitting approach with sociodemographic characteristics as covariates or interaction terms. ResultsAdjusting for sociodemographic factors, rural residents showed 85% higher odds of reporting at least one social or built environmental barrier (OR=1.85 [1.66, 2.07]). Compared to urban residents, rural residents showed significantly higher odds of reporting barriers to facility access (OR=4.15 [3.58, 4.83]) and a lack of social support to be active (OR=1.17 [1.04, 1.32]). Urban residents reported lower preference for physical activity, lower enjoyment of physical activity and lower confidence in their ability to regularly engage in physical activity. Interactions between socioeconomic status and location were identified related to enjoyment and confidence to be active. There was no effect of location on predicting the odds of reporting an individual resource-related variable (e.g., time, energy). ConclusionsDespite being more likely than urban residents to prefer and enjoy physical activity, rural residents have fewer opportunities and receive less social support to be active. It is important to consider geographic location when characterizing barriers to physical activity and in the development of context-specific health promotion strategies.

Neoliberalization and inequality: disparities in access to affordable housing in urban Canada 1981–2016

The neoliberalization of housing policy and housing financialization have brought unequal impacts on housing outcomes. Drawing on eight waves of census data, this study uncovers the changing mechanism of housing stratification in selected Canadian census metropolitan areas from 1981 to 2016, a period when Canada transitioned from a welfare housing regime to a neoliberal regime. This study reveals entrenched housing inequality and strengthened income effect in determining access to affordable housing in the neoliberal era. Housing financialization has significantly contributed to intensified inequality in accessing affordable housing. Access to affordable housing in Canada is also stratified along the lines of gender and immigration status. Homeownership affordability for low-to-moderate-income households has significantly deteriorated over time, representing a new form of housing vulnerability in the neoliberal era.

Rural Identities in an Urban Canada: Minority Rights for Agrarian Communities?

ABSTRACT Engaging with the theoretical literature on liberalism and minority cultural rights generated by Canadian scholars Will Kymlicka, Charles Taylor, and Alan Patten, this article offers an initial evaluation of the claim that rural agrarian communities exist as minority cultural communities bound together by a strong collective identity and conception of the good and are therefore deserving of certain group-differentiated rights designed to thwart their decline. Although it may appear unusual to locate a community held together by an economic activity on a scale equal to other, more commonly mentioned minority groups held together by ethnicity, religion, or language, this article highlights some shared “formative conditions” that bind this community together in a cultural way before concluding that there is reason to believe that liberal justice may require certain rights be made available to such communities. The article closes with a brief consideration of the policy implications of such a finding.

Migration and Resilience in Urban Canada: Why Social Resilience, Why Now?

Drawing on an extensive review of recent literature about resilience and integration, this paper evaluates a social resilience approach to the integration of international migrants in Canadian cities. We advocate a social resilience approach that acknowledges how institutions of all types play critical roles in newcomers’ efforts to establish their lives in new places, especially when faced with unanticipated events such as a global pandemic. Centering research around the concept of social resilience goes beyond the neoliberal idea that integration is primarily an individual affair achieved with support from friends, family, and a nebulous community and draws attention to the social diversity of migrants and the complexity of their migration and settlement histories. Inherently relational, a social resilience approach encourages comparative studies of integration across cities that can reveal how different institutions and their programs affect migrants’ trajectories. Detailed examinations of local institutions and their responses to shifting selection and integration policies, especially during a pandemic, also hold the potential to provide crucial information for supporting newcomers effectively.

Ethnocultural and socioeconomic disparities in exposure to residential greenness within urban Canada.

Residential greenness has been associated with health benefits, such as lower risk of mortality, cardiovascular disease, obesity, adverse birth outcomes and asthma and better psychological health. However, the variation in greenness across socioeconomic and demographic characteristics in urban areas of Canada has not been well documented. Respondents to the 2016 Census long-form questionnaire were assigned estimates of exposure to residential greenness based on the mean Normalized Difference Vegetation Index (NDVI) (from 2012 or the most recent year available) within a 500 m buffer around their home, based on postal code. Census weights were used to determine differences in average exposure to greenness according to selected demographic and socioeconomic characteristics. Mean residential greenness among the 5.3 million census respondents in urban Canada was 0.44 units of the NDVI (standard deviation = 0.18 units). Greenness was lower among immigrants (particularly recent immigrants), some groups designated as visible minorities (particularly people of Filipino ancestry), lower-income households and tenants (i.e., NDVI values ranging from 0.40 to 0.43 units). Greenness values were highest among White non-immigrants and higher-income households (i.e., NDVI values ranging from 0.46 to 0.47 units). Given the potentially multifaceted role that greenness plays in health outcomes, the inequalities in residential greenness described here may contribute to producing or exacerbating existing health inequalities in the Canadian population.

Explaining cross-cultural variation in mirror self-recognition: New insights into the ontogeny of objective self-awareness.

Mirror self-recognition (MSR) is considered to be the benchmark of objective self-awareness-the ability to think about oneself. Cross-cultural research showed that there are systematic differences in toddlers' MSR abilities between 18 and 24 months. Understanding whether these differences result from systematic variation in early social experiences will help us understand the processes through which objective self-awareness develops. In this study, we examined 57 18- to 22-month-old toddlers (31 girls) and their mothers from two distinct sociocultural contexts: urban Canada (58% of the subsample were Canadian-born native English-speakers) and rural Vanuatu, a small-scale island society located in the South Pacific. We had two main goals: (a) to identify the social-interactional correlates of MSR ability in this cross-cultural sample, and (b) to examine whether differences in passing rates could be attributed to confounding factors. Consistent with previous cross-cultural research, ni-Vanuatu toddlers passed the MSR test at significantly lower rates (7%) compared to their Canadian counterparts (68%). Among a suite of social interactive variables, only mothers' imitation of their toddlers' behavior during a free play session predicted MSR in the entire sample and maternal imitation partially mediated the effects of culture on MSR. In addition, low passing rates among ni-Vanuatu toddlers could not be attributed to reasons unrelated to self-development (i.e., motivation to show mark-directed behavior, understanding mirror-correspondence, representational thinking). This suggests that differences in MSR passing rates reflect true differences in self-recognition, and that parental imitation may have an important role in shaping the construction of visual self-knowledge in toddlers.

How Do Health Systems Address Patient Flow When Services Are Misaligned With Population Needs? A Qualitative Study.

Patient flow through health services is increasingly recognized as a system issue, yet the flow literature has focused overwhelmingly on localized interventions, with limited examination of system-level causes or remedies. Research suggests that intractable flow problems may reflect a basic misalignment between service offerings and population needs, requiring fundamental system redesign. However, little is known about health systems' approaches to population-capacity misalignment, and guidance for system redesign remains underdeveloped. This qualitative study, part of a broader investigation of patient flow in urban Western Canada, explored health-system strategies to address or prevent population-capacity misalignment. We conducted in-depth interviews with a purposive sample of managers in 10 jurisdictions across 4 provinces (N = 300), spanning all healthcare sectors and levels of management. We used the constant comparative method to develop an understanding of relevant strategies and derive principles for system design. All regions showed evidence of pervasive population-capacity misalignment. The most superficial level of response - mutual accommodation (case-by-case problem solving) - was most prevalent; capacity (re)allocation occurred less frequently; population redefinition most rarely. Participants' insights yielded a general principle: Define populations on the basis of clusters of co-occurring need. However, defining such clusters demands a difficult balance between narrowness/rigidity and breadth/flexibility. Deeper analysis suggested a further principle: Populations that can be divided into homogeneous subgroups experiencing similar needs (eg, surgical patients) are best served by narrow/ rigid models; heterogeneous populations featuring diverse constellations of need (eg, frail older adults) require broad/ flexible models. To remedy population-capacity misalignment, health system planners should determine whether clusters of population need are separable vs. fused, select an appropriate service model for each population, allocate sufficient capacity, and only then promote mutual accommodation to address exceptions. Overreliance on case-by-case solutions to systemic problems ensures the persistence of population-capacity misalignment.

Trends in mental health inequalities in urban Canada.

Canadians do not all enjoy equal levels of health. The presence of income-related health inequalities has been well established in Canada, but there is a lack of consistent reporting of mental health inequalities in Canada's largest cities. This study reports the prevalence and inequalities in mental health outcomes at the city, provincial, and national levels over time. Self-reported poor mental health, life stress, and physician-diagnosed self-reported mood and anxiety disorder from the Canadian Community Health Survey were pooled over five-year intervals and combined with neighbourhood income information from the Canadian Census. First, prevalence rates were calculated for each interval at the neighbourhood level for urban communities. Second, the distributions of these neighbourhood rates were summarized at the city level and for Canada as a whole using overall prevalence rates and concentration indices of inequality. Finally, trends in these city- and country-level outcomes were also explored. At the national level, starting from 2001 to 2005, the prevalence of poor mental health (27.9%), mood disorder (7.3%), and anxiety disorder (6.8%) had significantly increased by 2011-2015. Inequalities were present in 2001-2005 and worsened over time. The prevalence rate at the national level of life stress was 66.6% in 2001-2005 and decreased over time. The large and increasing values of inequalities and the difference in prevalence rates and inequalities in cities highlight the necessity for mental disorder-specific data and for city-level analysis of inequalities. The next steps in reducing inequalities involve deconstructing the health inequalities, and continued monitoring.

Connectedness to Nature and Pro-Environmental Behaviour from Early Adolescence to Adulthood: A Comparison of Urban and Rural Canada

Previous research has demonstrated that emotional connectedness to nature is among the strongest predictors of pro-environmental behaviour. This study investigated the influence of age, gender and living context on emotional connectedness to nature and pro-environmental behaviour in a Canadian sample. Study participants completed an environmental survey, which assessed demographic data as well as levels of emotional connectedness to nature and pro-environmental behaviour. The study contained 1251 participants equally divided across gender, sampled from four different age groups in rural versus urban living contexts throughout Canada. Study results revealed that emotional connectedness to nature was the strongest predictor of pro-environmental behaviour in comparison to the other factors. It was found that adults displayed significantly higher levels of emotional connectedness to nature and pro-environmental behaviour in comparison to adolescents, and that females displayed higher levels of both emotional connectedness to nature and pro-environmental behaviour in comparison to males. Moreover, urban and rural participants significantly differed in their levels of pro-environmental behaviour, but not in their levels of emotional connectedness to nature.

Social (In)justice and Rental Housing Discrimination in Urban Canada: The Case of Ethno-racial Minorities in the Herongate Community in Ottawa

In 2015, the predominantly visible minority immigrant community of Herongate, in Ottawa, Ontario, was slated for redevelopment by its landlord, Timbercreek Asset Management. This redevelopment involved mass eviction of the incumbent tenants, demolition of the existing affordable housing and its replacement with luxury rentals, which, by all indications, are beyond the financial reach of the former Herongage tenants. This paper seeks to problematize large-scale residential real estate redevelopment in Canada and examine its impact, using the Herongate situation as a case study. Among other things, it profiles the Herongate community, its history and present redevelopment, and explores the legal framework, and the limits thereof, constraining mass evictions of this type in Ontario. The findings indicate that the selection of Herongate for redevelopment was not fortuitous; generally, racialized and immigrant communities like Herongate are disproportionately likely to be selected for large-scale redevelopment projects, and thus subjected to mass-evictions. Further results suggest that the dissolution of the Herongate community – and the attendant dislocation of its members – has exacted a pronounced social and economic toll and compounded the racial discrimination already experienced by the former Herongate residents, most of whom are visible minorities. The paper concludes with an appeal to imbue the redevelopment process with a greater regard for social justice, and a right to housing as a policy solution to address the injustice caused by real estate redevelopment.

Fit for Dialysis: a prospective 2-site parallel intervention trial of a filmed research-based drama to increase exercise amongst older hemodialysis patients.

The present study aimed to evaluate the impact of a filmed research-based drama-Fit for Dialysis-and an exercise program on patients' physical activity and fitness outcomes. Nineteen (10 at the intervention site, 9 at the control site) older patients with a medical diagnosis of hemodialysis-dependent end-stage renal disease were recruited from two acute care hospitals in urban central Canada where they were receiving out-patient hemodialysis care. Participants at the intervention site viewed Fit for Dialysis prior to participating in a 16-week exercise program. Participants at the control site participated only in the 16-week exercise program. Physical activity, measured by total intradialytic exercise time (TIDE), and physical fitness, measured by the Two-Minute Walk Test (2MWT). Secondary measures included: Timed Up and Go (TUG), Grip Strength, Duke Activity Status Index (DASI), Godin Leisure-Time Exerciser Questionnaire (GLTEQ), and pedometer step count. TIDE, TUG, and GLTEQ were better at the intervention site compared to the control site at all time points measured. However, the change over time was not different between the sites. The 2MWT improved over time at the intervention site for those who exercised consistently. No significant differences between sites, or over time were found for any of the other measures. Further research is needed to determine the effectiveness of this intervention to facilitate the incorporation of exercise into the care and treatment of HD patients.
