'I thought we would be cherished and safe here': understanding the multi-faceted nature of mental health among Arab immigrants/refugees in Ontario, Canada- the CAN-HEAL study.

PURPOSE: Mental health (MH) is a critical public health issue. Arab immigrants/refugees (AIR) may be at high risk for MH problems owing to various unique stressors, such as post-September/11 demonization. Despite the growing AIR population in Western countries, there is a lack of AIR-MH research in these nations. The CAN-HEAL study examined MH experiences and needs among AIR in Ontario, Canada. METHODS: This study employed a cooperative community-based participatory research and integrated knowledge translation approach. The study used photovoice, qualitative interviews and a questionnaire survey. Sixty socio-demographically diverse AIR adults partook in this study. The research was informed by the "social determinants of health" framework and the "years since immigration effect" (YSIE) theory. RESULTS: The term "mental health" was deemed offensive for participants aged > 30 years. Participants proposed other culturally-appropriate words including "well-being" and "emotional state". The prevalence of poor mental well-being in the sample was alarming (55%). Of first-generation immigrant participants, 86.8% reported negative changes in MH since migration. The negative changes are not straightforward; they are complex and dynamic, and mainly related to micro/macro-aggression, cross-cultural pressures, dissatisfaction with the health and social care system, and poor living conditions. Intersections between different socio-demographic factors (e.g., gender, length of residency, income, parenthood, religion) amplified the negative changes in MH and exacerbated inequities. CONCLUSIONS: MH needs among AIR are distinct and intersectionality aggravated inequities. Culturally and structurally competent healthcare and structural/policy reformation are required to tackle MH inequities. This can be fulfilled through intersectoral cooperation and including AIR in decision-making.

'I thought we would be nourished here': The complexity of nutrition/food and its relationship to mental health among Arab immigrants/refugees in Canada: The CAN-HEAL study.

Nutritional psychiatry suggests that diet quality impacts one's mental health (MH). The relationship between food/nutrition and MH may be particularly salient for immigrants/refugees who often experience high risk for household food insecurity and MH challenges. An innovative collaborative community-based participatory research and integrated knowledge translation approach was adopted to explore food/nutrition needs as they relate to MH among Arab immigrants/refuges (AIR) in Ontario, Canada. The goal was to co-identify areas that require social change and co-produce applicable knowledge for service improvement. The CAN-HEAL study used a multi-methodological approach, employing qualitative interviews, photovoice and a questionnaire survey. A combination of three sampling approaches (convenience, snowball and purposive) was used to recruit sixty socio-demographically-diverse adult AIR participants. The research was guided by an integrated bio-psycho-socio-cultural framework. Participants reported various socio-economic and structural barriers to nutritious eating. Food quality/safety was a significant concern and source of anxiety among AIR; food mislabeling, the widespread presence of genetically/chemically modified foods and expired/rotten food products were associated with negative MH. Participants experienced an alarming prevalence of food insecurity (65%), which was associated with negative MH. Intersections among age, gender, religion, socio-economic status, parenthood, disability, and place of residence played a considerable role in how nutrition, food security, and dietary intake impacted AIR's MH and caused substantial disparities within the AIR community. The food/nutrition-MH relationship among AIR is multi-faceted, and various psycho-socio-cultural pathways/processes were found to shape MH. Intersectoral collaboration between health and non-health sectors is needed to implement a co-proposed socio-political and community-level action plan to achieve nutrition and health equity for AIR and other similar marginalized groups.

Monitoring mobility in older adults using a Global Positioning System (GPS) smartwatch and accelerometer: A validation study.

There is growing interest in identifying valid and reliable methods for detecting early mobility limitations in aging populations. A multi-sensor approach that combines accelerometry with Global Positioning System (GPS) devices could provide valuable insights into late-life mobility decline; however, this innovative approach requires more investigation. We conducted a series of two experiments with 25 older participants (66.2±8.5 years) to determine the validity of a GPS enabled smartwatch (TicWatch S2 and Pro 3 Ultra GPS) and separate accelerometer (ActiGraph wGT3X-BT) to collect movement, navigation and body posture data relevant to mobility. In experiment 1, participants wore the TicWatchS2 and ActiGraph simultaneously on the wrist for 3 days. In experiment 2, participants wore the TicWatch Pro 2 Ultra GPS on the wrist and ActiGraph on the thigh for 3 days. In both experiments participants also carried a Qstarz data logger for trips outside the home. The TicWatch Pro 3 Ultra GPS performed better than the S2 model and was similar to the Qstarz in all tested trip-related measures, and it was able to estimate both passive and active trip modes. Both models showed similar results to the gold standard Qstarz in life-space-related measures. The TicWatch S2 demonstrated good to excellent overall agreement with the ActiGraph algorithms for the time spent in sedentary and non-sedentary activities, with 84% and 87% agreement rates, respectively. Under controlled conditions, the TicWatch Pro 3 Ultra GPS consistently measured step count in line with the participants' self-reported data, with a bias of 0.4 steps. The thigh-worn ActiGraph algorithm accurately classified sitting and lying postures (97%) and standing postures (90%). Our multi-sensor approach to monitoring mobility has the potential to capture both accelerometer-derived movement data and trip/life-space data only available through GPS. In this study, we found that the TicWatch models were valid devices for capturing GPS and raw accelerometer data, making them useful tools for assessing real-life mobility in older adults.

Strengthening Community Roots: Anchoring Newcomers in Wellness and Sustainability (SCORE!): A protocol for the co-design and evaluation of a healthy active living program among a newcomer community in Canada.

BACKGROUND: The burden of childhood obesity and cardiometabolic risk factors affecting newcomer Canadians living in lower socioeconomic circumstances is a concerning public health issue. This paper describes Strengthening Community Roots: Anchoring Newcomers in Wellness and Sustainability (SCORE!), an academic-community research partnership to co-design interventions that nurture and optimize healthy activity living (HAL) among a community of children and families new to Canada in Hamilton, Ontario, Canada. METHODS/DESIGN: Our overarching program is informed by a socio-ecological model, and will co-create HAL interventions for children and families new to Canada rooted in outdoor, nature-based physical activity. We will proceed in three phases: Phase 1) synthesis of existing evidence regarding nature based HAL interventions among children and families; Phase 2) program development through four data collection activities including: i) community engagement activities to build trustful relationships and understand barriers and facilitators, including establishing a community advisory and action board, qualitative studies including a photovoice study, and co-design workshops to develop programs; ii) characterizing the demographics of the community through a household survey; iii) characterizing the built environment and HAL programs/services available in the community by developing an accessible real-time systems map; and iv) reviewing municipal policies relevant to HAL and sustainability; leading to Phase 3) implementation and evaluation of the feasibility of co-designed HAL programs. CONCLUSION: The etiology of childhood obesity and related chronic diseases is complex and multifactorial, as are intervention strategies. The SCORE! program of research brings together partners including community members, service providers, academic researchers, and organizational leaders to build a multi-component intervention that promotes the health and wellness of newcomer children and families.

A Scoping Review of the Relationship Between Physical Activity and Mental Health Among Immigrants in Western Countries: An Integrated Bio-Psycho-Socio-Cultural Lens.

Epidemiological evidence suggests that regular physical activity (PA) positively impacts individuals' mental health (MH). The PA-MH relationship may be critical among immigrants owing to psycho-social-cultural influences. This scoping review of 61 studies employed a holistic bio-psycho-socio-cultural framework to thoroughly investigate the complex relationship between PA (across life domains) and immigrants' MH in Western countries. A systematic search of five electronic databases (Medline, PubMed, Embase, PsycINFO and Anthropology Plus) was conducted to locate relevant articles. No limitations were applied to study design, age, gender, home country, MH condition or PA type. A bio-psycho-socio-cultural-informed conceptual model guided the analysis of the multi-domain PA-MH relationship. Immigrant PA-MH studies were conducted and reported most commonly in the USA (38%), Australia (18%), and Canada (11%). Overall, PA was positively related to MH. Each domain-specific PA appeared to be associated with unique MH-promoting pathways/mechanisms. Leisure-related PA may support MH by enhancing self-agency and minimizing risky behaviors, whilst travel- and domestic-related PA may promote self-accomplishment and physical engagement. Ethnic sports appeared to enhance resilience. Occupational-related PA was associated with either positive or negative MH, depending on the type of occupation. A bio-psycho-socio-cultural-informed model is required to gain an encompassing and integrated understanding of immigrants' health. The first iteration of such a model is presented here, along with an illustration of how the model may be used to deepen analysis and understanding of the multi-domain PA-MH relationship among immigrants and inform public health planners and practitioners.

Air Pollution Health Literacy among Active Commuters in Hamilton, Ontario.

The promotion of active transportation (AT), which has been broadly defined as a physical effort performed by the traveller to produce motion, has been a popular strategy to reduce vehicular emissions, improve air quality, and promote physical activity. However, individuals who engage in AT may incur increased exposure to air pollutants and thus potential health impacts. This research sought to determine how active commuters understand the health risks associated with air pollution during their commutes, and whether they engage in any behaviours to limit exposure. An online survey was adapted from the Environmental Health Literacy framework to assess air pollution health literacy among active commuters in Hamilton, ON, and generated a sample size of 192 AT users. Analyses involved the use of frequency tables and cross-tabulations for the quantitative data, and the Health Belief Model and thematic analysis to interpret the qualitative data. Results revealed that most AT users do not adopt behaviours that would limit air pollution exposure on commutes and exhibited low self-rated knowledge of the health impacts of air pollution exposure. Issues of perceived susceptibility and severity, barriers, cues to action, and self-efficacy all further impacted the likelihood of adopting health protective behaviours. Conclusively, air pollution is an often-neglected consideration among active commuters, with air pollution knowledge predicting the likelihood of behavioural modification.

Enhancing Physical and Community MoBility in OLDEr Adults with Health Inequities Using CommuNity Co-Design (EMBOLDEN): Results of an Environmental Scan.

Background: Using the comparatively new environmental scan methodology, a protocol was developed and conducted to inform the co-design and implementation of a novel intervention to promote mobility among older adults in Hamilton, Ontario, Canada. The EMBOLDEN program seeks to promote physical and community mobility in adults 55 years and older who face barriers accessing community programs and who reside in areas of high inequity in Hamilton, and to address the following areas of focus: physical activity, nutrition, social participation, and system navigation supports. Methods: The environmental scan protocol was developed using existing models and drew insights from census data, a review of existing services, organizational representative interviews, windshield surveys of selected high-priority neighbourhoods, and Geographic Information System (GIS) mapping. Results: A total of 98 programs for older adults from 50 different organizations were identified, with the majority (92) supporting mobility, physical activity, nutrition, social participation, and system navigation. The analysis of census tract data identified eight high-priority neighbourhoods characterized by large shares of older adults, high material deprivation, low income, and high proportion of immigrants. These populations can be hard to reach and face multiple barriers to participation in community-based activities. The scan also revealed the nature and types of services geared toward older adults in each neighbourhood, with each priority neighbourhood having at least one school and park. Most areas had a range of services and supports (i.e., health care, housing, stores, religious options), although there was a lack of diverse ethnic community centres and income-diverse activities specific to older adults in most neighbourhoods. Neighbourhoods also differed in the geographic distribution number of services, along with the number of recreational services specific to older adults. Barriers included financial and physical accessibility, lack of ethnically diverse community centres, and food deserts. Conclusions: Scan results will inform the co-design and implementation of the Enhancing physical and community MoBility in OLDEr adults with health inequities using commuNity co-design intervention-EMBOLDEN.

Age and domestic migration effects on workers' commuting distance.

Do older workers, including those that work beyond age 65, have different commuting patterns than their younger counterparts? With a focus on older working adults, including those that continue to work beyond age 65, this paper examines the relationship between migration, residential location, and commute distance within Toronto's commuter shed. The study utilizes data from the master file of the 2016 Canadian Census, allowing migrants to be disaggregated by duration of residence. Results indicate that living in rural areas and being a recent migrant are significantly associated with longer commutes. Furthermore, findings demonstrate that the commute distance of very recent migrants (those who migrated in the year immediately prior to the census) and individuals who moved to rural areas have the longest commute distances. As residential duration increases, commute distance decreases. Older workers have similar commuting behaviors as younger workers, although older workers who recently migrated have some of the longest commute distances as well.

Community-based group physical activity and/or nutrition interventions to promote mobility in older adults: an umbrella review.

BACKGROUND: Physical activity and a healthy diet are important in helping to maintain mobility with aging. This umbrella review aims to identify group-based physical activity and/or nutrition interventions for community-dwelling older adults that improve mobility-related outcomes. METHODS: Five electronic databases (MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Sociological Abstracts) were searched from inception to December 2021. Eligibility criteria included systematic reviews exploring the effectiveness of physical activity or structured exercise, alone or combined with nutrition interventions on mobility-related outcomes (aerobic capacity, physical function, balance, falls/safety, muscle strength, health-related quality of life/wellbeing). Interventions must have been delivered in a group setting to community-dwelling older adults aged 55+. Two reviewers independently performed eligibility screening, critical appraisal (using AMSTAR 2) and data extraction. The GRADE approach was used to reflect the certainty of evidence based on the size of the effect within each mobility-related outcome category. Older adult/provider research partners informed data synthesis and results presentation. RESULTS: In total, 62 systematic reviews (1 high, 21 moderate, 40 low/critically low quality) were identified; 53 included physical activity only, and nine included both physical activity and nutritional supplements. No reviews included nutrition interventions alone. Combined aerobic/resistance, general physical activity, and mind-body exercise all improved physical function and balance (moderate-high certainty). Aerobic/resistance training improved aerobic capacity (high certainty). Resistance training and general physical activity improved muscle strength (moderate certainty). Aerobic/resistance training and general physical activity are likely to reduce falls among older adults (moderate certainty). There was no evidence of benefit for nutritional supplementation with physical activity. CONCLUSIONS: Group-based physical activity interventions that combine aerobic and resistance, general PA and mind-body exercise can improve measures of mobility in community-dwelling older adults. We found no reviews focused on nutrition only, highlighting a gap in the literature.

Transport preferences and dilemmas in the post-lockdown (COVID-19) period: Findings from a qualitative study of young commuters in Dhaka, Bangladesh.

At the start of the pandemic in early 2020, many cities went to complete or partial lockdown to minimize the mass transmission of COVID-19. Consequently, personal travel patterns have changed throughout the world. This study explores the transport mode preferences and associated dilemmas that commuters face in Dhaka, Bangladesh, in the post-lockdown period. We conducted in-depth semi-structured interviews of 20 young commuters residing in Dhaka. We followed a deductive reasoning approach, and the transcriptions were analyzed following thematic analysis. Findings suggest that despite the perceived high risk of COVID-19 transmission in certain modes, all commuters don't have the ease and flexibility to switch to their preferred safer mode, with commuters trading-off between health risk, affordability and availability of suitable modes, along with other challenges. However, the country's sustainable goals can still be achieved if proper actions, such as removing the challenges commuters face while switching to a sustainable and safe mode during COVID-19 are taken.

Understanding the Healthy Immigrant Effect in the Context of Mental Health Challenges: A Systematic Critical Review.

The "Healthy Immigrant Effect" (HIE) suggests that immigrants have a health advantage over the domestic-born which vanishes with increased length of residency. Most HIE research focuses on physical health, with less attention given to mental health (MH). This systematic review of 58 MH studies examines whether there is a MH advantage among immigrants and explores changes in immigrants' MH, besides critically assessing the use of HIE theory. Inconsistent evidence was detected regarding the presence of MH advantage, whereas consistent, convincing evidence was revealed for a decline in immigrants' MH over years. Although the HIE theory can help reveal MH disparities, this theory alone does not explain the reasons for these disparities nor inform about potential avenues to improve immigrants' MH. A paradigm shift is needed to incorporate other potential theoretical concepts/frameworks, including the "Health Inequalities Action" framework, for a broader understanding of MH issues and to inform effective, culturally-sensitive interventions.

Impact of COVID-19 on mobility and participation of older adults living in Hamilton, Ontario, Canada: a multimethod cohort design protocol.

INTRODUCTION: The novel COVID-19 required many countries to impose public health measures that likely impacted the participation and mobility of community-dwelling older adults. This protocol details a multimethod cohort design undertaken to describe short-term and medium-term changes to the mobility and participation of older Canadians living in the community rather than retirement facilities during the COVID-19 pandemic. METHODS AND ANALYSIS: A longitudinal telephone (or online)-administered survey is being conducted with a random sample of older adults living within 20 km of McMaster University, Hamilton, Ontario, Canada, identified from census dissemination areas. Baseline data collection of community-dwelling older adults aged 65 years and over began in May 2020 with follow-ups at 3, 6, 9 and 12 months. The Late-Life Function and Disability Instrument and global rating of change anchors are the primary outcomes of interest. A subsample of respondents will participate in open-ended, semistructured interviews conducted over the telephone or through video-conference, to explore participants' lived experiences with respect to their mobility and participation during the pandemic. Descriptive statistics and quantitative approaches will be used to determine changes in mobility and social and personal participation, and associated personal and environmental factors. For the interviews, qualitative data will be analysed using descriptive phenomenology. ETHICS AND DISSEMINATION: Approval was obtained from the Hamilton Integrated Research Ethics Board of McMaster University (2020-10814-GRA). This study may inform the design of programmes that can support community-dwelling older adults during and after the COVID-19 pandemic. Findings will be disseminated through peer-reviewed publications and conferences focused on ageing.

Physical activity participation among Arab immigrants and refugees in Western societies: A scoping review.

Insufficient physical activity (PA) is the fourth prime risk factor for numerous non-communicable diseases. Arab immigrants and refugees (AIR) are at elevated risk for low or no participation in PA due to socio-cultural and ecological factors. This scoping review examined PA prevalence, knowledge, attitudes as well as barriers vs. facilitators to PA engagement across life domains among AIR in Western countries. A systematic search strategy was implemented across five automated databases (PubMed, Embase, Medline, Sociology Database and Transportation Research Board) to locate pertinent English language papers. Seventy-five articles were included in this study, and stakeholder consultation was conducted to validate the findings. The US and Europe are substantially ahead of Canada, Australia, and New Zealand in AIR-PA research. Despite showing positive attitudes and sound knowledge of PA recommendations, AIR exhibited a low PA engagement prevalence, revealing a knowledge-compliance gap. The prevalence of sufficient PA was lowest in the US (11-22%), whereas Europe showed the highest figures (26-45%). Personal barriers to PA participation involved mainstream language illiteracy and limited exercise skills, whereas improved PA literacy was a significant facilitator. Family responsibility and cultural restrictions were common psychosocial/cultural barriers, whereas social support and culturally-sensitive resources were powerful facilitators. Poorly maintained pedestrian/cyclist infrastructure was a leading environmental barrier amongst AIR in North America, but not Europe. Longitudinal and community-engaged AIR-PA research is needed, and intersectoral collaboration is required to inform tailored interventions and inclusive policies, fostering AIR and other vulnerable populations' exercise participation and improving their health and well-being.

Influences on mental health and health services accessibility in immigrant women with post-partum depression: An interpretive descriptive study.

WHAT IS KNOWN ABOUT THE SUBJECT?: Immigrant women in Canada are at greater risk for post-partum depression (PPD) than native-born women. Immigrant women are less likely to have their care needs met as they face multiple barriers to care at both individual and system levels. To date, most PPD research has focused on individual barriers to care, with limited research examining organizational and system level barriers and the uniqueness of immigrant women's post-partum health experiences. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study provides unique insights into immigrant women's perceptions of what influences their post-partum mental health and ability to access services for PPD. Factors contributing to immigrant women's PPD included several social determinants of health, particularly a lack of social support and limited knowledge about PPD and available services. Most helpful services acknowledge women's concerns, build trust, enact cultural competence and help with system navigation. Assessment approaches and organizational wait times created barriers to accessing care. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Relationship building by providers is foundational to effective care for immigrant women with PPD. Findings highlight the need for mental health practitioners to improve cultural competence when working with diverse ethno-cultural communities and for more effective assistance with system navigation, service integration and timely, flexible and accessible services. Findings have implications for the development of healthy public policy to address perinatal mental health issues amongst immigrant women. Abstract Introduction Immigrant women in Canada are at greater risk for post-partum depression (PPD) than native-born women yet face multiple barriers to care at individual and system levels. Aim To explore factors that contribute to PPD and health service accessibility, and the role of health services in supporting immigrant women with PPD. Methods A qualitative interpretive descriptive design was used. Individual interviews were conducted with 11 immigrant women who had delivered a baby within the previous year and had experienced PPD. Inductive thematic content analysis was conducted. Results Factors contributing to immigrant women's PPD included several social health determinants. Services were most helpful and accessible when providers acknowledged women's concerns, allowed time to build trust, provided culturally competent care and helped with navigating services. Assessment approaches and organizational wait times created barriers to care. Discussion Immigrant women with PPD see relationship building by providers as foundational to providing effective support, enhancing coping and facilitating access to services. Improved communication with diverse ethno-cultural communities and assistance with system navigation, service integration and timely, accessible services are needed. Implications for Practice Findings can inform health service delivery models and the development of healthy public policy to address perinatal mental health issues amongst immigrant women.

Low prioritization of latent tuberculosis infection-A systemic barrier to tuberculosis control: A qualitative study in Ontario, Canada.

BACKGROUND: Eliminating tuberculosis (TB) in low-incidence countries is an important global health priority, and Canada has committed to achieve this goal. The elimination of TB in low-incidence countries requires effective management and treatment of latent tuberculosis infection (LTBI). This study aimed to understand and describe the system-level barriers to LTBI treatment for immigrant populations in the Greater Toronto and Hamilton Area, Ontario, Canada. METHODS: A qualitative study that used purposive sampling to recruit and interview health system advisors and planners (n = 10), providers (n = 13), and clients of LTBI health services (n = 9). Data were recorded, transcribed verbatim, and analyzed using content analysis. RESULTS: Low prioritization of LTBI was an overarching theme that impacted four dimensions of LTBI care: management, service delivery, health literacy, and health care access. These factors explained, in part, inequities in the system that were linked to variations in health care quality and health care access. While some planners and providers at the local level were attempting to prioritize LTBI care, there was no clear pathway for information sharing. CONCLUSIONS: This multiperspective study identified barriers beyond the typical socioeconomic determinants and highlighted important upstream factors that hinder treatment initiation and adherence. Addressing these factors is critical if Canada is to meet the WHO's global call to eradicate TB in all low incidence settings.

Journey to Health: (Re) Contextualizing the Health of Canada's Refugee Population.

Existing literature on refugee health has often focused exclusively on either the post-arrival or pre-arrival experience. We believe the totality of each individual social identity should be acknowledged, including life prior to becoming a refugee. Thus, health status must be contextualized within pre-arrival health status and living conditions, health-care access, flight experiences, combined with post-arrival status: a fluid journey-to-health arc. The following article offers a holistic view of refugee health as an outcome of the entirety of this journey captured in a series of in-depth interviews with long-term, established service providers in Hamilton, Ontario. Our findings illustrate the importance of viewing health issues within the context of time and space. Refugees embark on fragmented journeys, leading to multiple challenges for providers, such as limited case histories, the absence of documentation and cultural (in)competence in terms of practice.

Barriers to treatment adherence for individuals with latent tuberculosis infection: A systematic search and narrative synthesis of the literature.

OBJECTIVES: We investigated the rates of initiation and completion of treatment for latent TB infection (LTBI), factors explaining nonadherence and interventions to improve treatment adherence in countries with low TB incidence. DESIGN: A systematic search was performed in PubMed and Embase. All included articles were assessed for risk of bias. A narrative synthesis of the results was conducted. RESULTS: There were 54 studies included in this review. The proportion of people initiating treatment varied from 24% to 98% and the proportion of people completing treatment varied from 19% to 90%. The main barriers to adherence included the fear or experience of adverse effects, long duration of treatment, financial barriers, lack of transport to clinics (for patients), and insufficient resources for LTBI control. While interventions like peer counseling, incentives, and culturally specific case management have been used to improve adherence, the proportion of people who initiate and complete LTBI treatment still remains low. CONCLUSION: To further improve treatment and LTBI control and to fulfill the World Health Organization goal of eliminating TB in low-incidence countries, greater priority should be given to the use of treatment regimens involving shorter durations and fewer adverse effects, like the 3-month regimen of weekly rifapentine plus isoniazid, supported by innovative patient education and incentive strategies.

Factors influencing health care and service providers' and their respective "at risk" populations' adoption of the Air Quality Health Index (AQHI): a qualitative study.

BACKGROUND: The Air Quality Health Index (AQHI) provides air quality and health information such that the public can implement health protective behaviours (reducing and/or rescheduling outdoor activity) and decrease exposure to outdoor air pollution. The AQHI's health messages account for increased risk associated with "at risk" populations (i.e. young children, elderly and those with pre-existing respiratory and/or cardiovascular conditions) who rely on health care and service providers for guidance. Using Rogers' Diffusion of Innovations theory, our objective with respect to health care and service providers and their respective "at risk" populations was to explore: 1) level of AQHI knowledge; 2) factors influencing AQHI adoption and; 3) strategies that may increase uptake of AQHI, according to city divisions and socioeconomic status (SES). METHODS: Semi-structured face-to-face interviews with health care (Registered Nurses and Certified Respiratory Educators) and service providers (Registered Early Childhood Educators) and focus groups with their respective "at risk" populations explored barriers and facilitators to AQHI adoption. Participants were selected using purposive sampling. Each transcript was analyzed using an Interpretive Description approach to identify themes. Analyses were informed by Rogers' Diffusion of Innovations theory. RESULTS: Fifty participants (6 health care and service providers, 16 parents, 13 elderly, 15 people with existing respiratory conditions) contributed to this study. AQHI knowledge, AQHI characteristics and perceptions of air quality and health influenced AQHI adoption. AQHI knowledge centred on numerical reliance and health protective intent but varied with SES. More emphasis on AQHI relevance with respect to health benefits was required to stress relative advantage over other indices and reduce index confusion. AQHI reporting at a neighbourhood scale was recognized as addressing geographic variability and uncertainty in perceived versus measured air quality impacting health. Participants predominantly expressed that they relied on sensory cues (i.e. feel, sight, taste) to determine when to implement health protective behaviours. Time constraints were identified as barriers; whereas local media reporting and wearable devices were identified as facilitators to AQHI adoption. CONCLUSION: Increasing knowledge, emphasizing relevance, and reporting AQHI information at a neighbourhood scale via local media sources and wearable devices may facilitate AQHI adoption while accounting for SES differences.

Comparing disability amongst immigrants and native-born in Canada.

Given high levels of immigration into Canada and the associated requirement to understand the health needs of new arrivals, an extensive literature has developed over the past decade that has explored immigrant health issues, including the 'healthy immigrant effect'. Surprisingly, however, issues of disability within the immigrant population have received much less attention. Using data from Statistics Canada, 2006a, 2006b Participation and Activity Limitation Survey (PALS), this paper examines disability and its covariates amongst immigrants relative to non-immigrants in Canada. Compared with their native-born counterparts, recent immigrant arrivals (within the past 10 years) were less likely to report disability and less likely to report a severe disability than the native-born. However, differences in the rates and covariates of disabilities between males and female immigrants were observed, which are partially explained by socioeconomic and sociodemographic effects. The conclusion explores potential reasons why differentials in disability rates are observed, and points to future research directions.

Building obesity in Canada: understanding the individual- and neighbourhood-level determinants using a multi-level approach.

The objective of this paper was to identify heterogeneities associated with the relationships between the body mass index (BMI) and individual as well as socio-environmental correlates at the individual- and area-levels. The data sources used were: (i) the 2003 Canadian Community Health Survey; (ii) the 2001 Canadian Census; and (iii) the Enhanced Points of Interest (EPOI) database from the Desktop Mapping Technologies Inc. Participants were adults (≥ 20 years; n = 12,836; based on a survey weight scheme N(weighted) = 5,418,218) from Toronto and Vancouver census metropolitan areas with no missing BMI records. In addition to conventional 1 km-buffers, we constructed activity-space-buffers to better assess the walkability and potentially increased BMI of individuals. Multi-level analysis was then applied to estimate the relative effects of both individual- and area-level risk-factors for increased BMI. The findings demonstrate a negative association between BMI and energy expenditure, mixed land uses, residential density and average value of dwellings, while a positive association was found with low educational attainment. Relationships were independent of individual characteristics such as age and ethnicity. Although the majority of the variation in these outcomes was found to be due to individual-level differences, this study did show significant differences at the area-level as well. The activity-space-buffers presented a vast improvement compared to the conventional 1 km-buffers. The results presented support the rationale that targeting high-risk individuals will only address a portion of the increasing BMI problem; it is essential to also address the characteristics of places that compel individuals to make unhealthy choices.
