InterACTIVE Interpreted Interviews (I3): A multi-lingual, mobile method to examine the neighbourhood environment with older adults

Biological age and environmental risk factors for dementia and stroke: Molecular mechanisms

Since the development of antibiotics and vaccination, as well as major improvements in public hygiene, the main risk factors for morbidity and mortality are age and chronic exposure to environmental factors, both of which can interact with genetic predispositions. As the average age of the population increases, the prevalence and costs of chronic diseases, especially neurological conditions, are rapidly increasing. The deleterious effects of age and environmental risk factors, develop chronically over relatively long periods of time, in contrast to the relatively rapid deleterious effects of infectious diseases or accidents. Of particular interest is the hypothesis that the deleterious effects of environmental factors may be mediated by acceleration of biological age. This hypothesis is supported by evidence that dietary restriction, which universally delays age-related diseases, also ameliorates deleterious effects of environmental factors. Conversely, both age and environmental risk factors are associated with the accumulation of somatic mutations in mitotic cells and epigenetic modifications that are a measure of "biological age", a better predictor of age-related morbidity and mortality than chronological age. Here we review evidence that environmental risk factors such as smoking and air pollution may also drive neurological conditions, including Alzheimer's Disease, by the acceleration of biological age, mediated by cumulative and persistent epigenetic effects as well as somatic mutations. Elucidation of such mechanisms could plausibly allow the development of interventions which delay deleterious effects of both aging and environmental risk factors.

Conducting a Mixed-Methods Study with Older Adults in Five Languages: Lessons from the Field

One third of older adults in Canada are foreign-born, yet there is a dearth of literature on this population. When our team set out to engage in a mixed-methods study on the physical activity and mobility of foreign-born older adults (FBOAs), we found limited guidance. The objective of this Research Note is to share the lessons that we learned in implementing a mixed-methods study in five languages, with 49 visible minority FBOAs from diverse ethno-cultural groups. With an emphasis on practical implementation, here we share our reflections on early community engagement, linguistic accessibility and literacy considerations, facilitating communication with the research team, creating a support role for multilingual family members, organisational suggestions, and working with interpreters and monolingual transcribers. The older Canadian population is projected to become increasingly diverse in the coming decades, and it is our hope that this note will further facilitate research in this understudied area.

"The Social Side Is as Important as the Physical Side": Older Men's Experiences of Physical Activity

North American “hegemonic masculinity” values strength, autonomy, independence, and resilience among its ideals. As men age, their capacity is increasingly challenged and demands that they adapt to new physical and social realities. Although some reports on effective health-promoting programs for men are emerging, there is a need to better understand older men’s experiences with their mobility and physical activity. This is a photovoice study with men (N = 14) who were enrolled in a choice-based activity program for low active men. Based on in-depth interviews and analysis of over 800 photographs, three key themes emerged: the importance of social connectedness, supportive environments, and positive attitude toward the future. Findings are presented via a theoretical view of masculinities as socially constructed through relational behaviors and norms. Analyses provide insight into older men’s motivation to be physically active and highlight the need for programs and policies customized to promote physical activity of older men.

Video for Knowledge Translation: Engaging Older Adults in Social and Physical Activity

Une vaste majorité des Canadiens âgés ne pratiquent pas suffisamment d'activité physique. Le développement de stratégies originales et innovantes encourageant et appuyant les modes de vie actifs est donc urgent. La vidéo est un outil prometteur pour l'application de connaissances (AC) visant l'engagement de divers publics dans la discussion et l'adoption de comportements favorisant la santé. L'Approche systématique pour les vidéos fondées sur des données probantes (Systematic Approach to Evidence-informed Video, SAEV), qui fournit un cadre pour guider et structurer le développement de vidéos ayant pour objectif l'AC, a été utilisée pour la création et la diffusion d'un documentaire de 19 minutes, I'd Rather Stay (https://vimeo.com/80503957). Quarante-huit participants âgés de 60 ans et plus ont visionné la vidéo, participé à des groupes de discussion et rempli des questionnaires concernant cette vidéo. Les données ont été recueillies après le visionnement et lors d'un suivi organisé six mois plus tard. La vidéo a éduqué, encouragé et mobilisé les personnes âgées sur les questions liées à l'autonomie, à l'activité physique et aux liens sociaux. Nous encourageons les chercheurs à adopter des stratégies d'AC auxquelles les personnes âgées peuvent s'identifier, qui sont accessibles et par lesquelles elles peuvent s'engager à un niveau critique, autant sur le plan émotionnel qu'intellectuel, comme les vidéos basées sur des preuves scientifiques.

Most older Canadians do not engage in sufficient physical activity. There is an urgent need for outside-the-box strategies that encourage and sustain active lifestyles. Video is a promising knowledge translation (KT) tool to engage diverse audiences in discussion and action around health promoting behaviours. We adopted a KT framework to inform a structured process of video development we have named systematic approach to evidence-informed video (SAEV). This guided the creation and dissemination of a 19-minute documentary video: I’d Rather Stay (https://vimeo.com/80503957). Following screenings, we collected focus group and questionnaire data from 48 participants aged 60 years and older at baseline and 6-month follow-up. The video educated, encouraged, and activated older people around issues such as independence, physical activity and social connectedness. We encourage researchers to adopt KT strategies – and to use evidence-informed video – that older adults can relate to and critically engage with on an accessible, emotional, and intellectual level.

The body language of place: A new method for mapping intergenerational "geographies of embodiment" in place-health research

Research on place and health has grown rapidly in recent years, including examining the physiological embodiment of place-based exposures. While this research continues to improve understanding of why place matters, there is particular need for work capable of revealing: 1) which places matter, i.e. spatially-specific notions of "place"); 2) how these places matter-processes and mechanisms of the physiological embodiment of place; and 3) potential intergenerational and life stage differences in place-embodiment experiences/perceptions. The research presented here seeks to make contributions in each of these areas through developing the "geographies of embodiment" concept. Drawing from a multi-method intergenerational community-based participatory research project examining place and health, the research presented here specifically highlights X-Ray Mapping as a new methodology to elucidate subjective notions of place-embodiment within place-health research. Participants were recruited as parent-child dyads and trained in four participatory research methods, including X-Ray Mapping. Participants used X-Ray Mapping and a multimedia-enabled web-based mapping platform to map their "geographies of embodiment". X-Ray Mapping results revealed that 49% of youth place-embodiment locations were spatially outside of their residential census tract-with 75% of positive place-embodiment locations outside, and 66% of negative place-embodiment locations inside. Overall, 67% of youth and adult positive place-embodiment locations were outside of their residential census tract. Through mapping "geographies of embodiment" via participatory methods like X-Ray Mapping, we can gain greater insight into what is embodied (i.e. specific experiences/exposures), and where (i.e. spatially-specific). These gains could improve development of quantitative place-health metrics and enhance efforts to uncover/intervene on the "pathways of embodiment"-specifically, those elements of local social, political, economic, and environmental contexts that constitute expressions of social inequality.

INTERACT: A comprehensive approach to assess urban form interventions through natural experiments

BACKGROUND

Urban form interventions can result in positive and negative impacts on physical activity, social participation, and well-being, and inequities in these outcomes. Natural experiment studies can advance our understanding of causal effects and processes related to urban form interventions. The INTErventions, Research, and Action in Cities Team (INTERACT) is a pan-Canadian collaboration of interdisciplinary scientists, urban planners, and public health decision makers advancing research on the design of healthy and sustainable cities for all. Our objectives are to use natural experiment studies to deliver timely evidence about how urban form interventions influence health, and to develop methods and tools to facilitate such studies going forward.

METHODS

INTERACT will evaluate natural experiments in four Canadian cities: the Arbutus Greenway in Vancouver, British Columbia; the All Ages and Abilities Cycling Network in Victoria, BC; a new Bus Rapid Transit system in Saskatoon, Saskatchewan; and components of the Sustainable Development Plan 2016-2020 in Montreal, Quebec, a plan that includes urban form changes initiated by the city and approximately 230 partnering organizations. We will recruit a cohort of between 300 and 3000 adult participants, age 18 or older, in each city and collect data at three time points. Participants will complete health and activity space surveys and provide sensor-based location and physical activity data. We will conduct qualitative interviews with a subsample of participants in each city. Our analysis methods will combine machine learning methods for detecting transportation mode use and physical activity, use temporal Geographic Information Systems to quantify changes to urban intervention exposure, and apply analytic methods for natural experiment studies including interrupted time series analysis.

DISCUSSION

INTERACT aims to advance the evidence base on population health intervention research and address challenges related to big data, knowledge mobilization and engagement, ethics, and causality. We will collect ~ 100 TB of sensor data from participants over 5 years. We will address these challenges using interdisciplinary partnerships, training of highly qualified personnel, and modern methodologies for using sensor-based data.
