Assessing the Influence of the Built Environment on Physical Activity for Utility and Recreation in Suburban Metro Vancouver

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2011
Abstract: 

Background:

Physical inactivity and associated co-morbidities such as obesity and cardiovascular disease areestimated to have large societal costs. There is increasing interest in examining the role of the built environment inshaping patterns of physical activity. However, few studies have: (1) simultaneously examined physical activity forleisure and utility; (2) selected study areas with a range of built environment characteristics; and (3) assessed thebuilt environment using high-resolution land use data.

Methods:

Data on individuals used for this study are from a survey of 1602 adults in selected sites acrosssuburban Metro Vancouver. Four types of physical activity were assessed: walking to work/school, walking forerrands, walking for leisure and moderate physical activity for exercise. The built environment was assessed byconstructing one-kilometre road network buffers around each respondent’s postal code. Measures of the builtenvironment include terciles of recreational and park land, residential land, institutional land, commercial land andland use mix.

Results:

Logistic regression analyses showed that walking to work/school and moderate physical activity were notassociated with any built environment measure. Living in areas with lower land use mix, lower commercial andlower recreational land increased the odds of low levels of walking for errands. Individuals living in the lower thirdof land use mix and institutional land were more likely to report low levels of walking for leisure.

Conclusions:

These results suggest that walking for errands and leisure have a greater association with the builtenvironment than other dimensions of physical activity.

Comparing Circular and Network Buffers to Examine the Influence of Land Use on Walking for Leisure and Errands

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2007
Abstract: 

Background: There is increasing interest in examining the influence of the built environment onphysical activity. High-resolution data in a geographic information system is increasingly being usedto measure salient aspects of the built environment and studies often use circular or road networkbuffers to measure land use around an individual's home address. However, little research hasexamined the extent to which the selection of circular or road network buffers influences theresults of analysis.The objective of this study is to examine the influence of land use type (residential, commercial,recreational and park land and institutional land) on 'walking for leisure' and 'walking for errands'using 1 km circular and line-based road network buffers. Data on individual walking patterns isobtained from a survey of 1311 respondents in greater Vancouver and respondent's postal codecentroids were used to construct the individual buffers. Logistic regression was used for statisticalanalysis.Results: Using line-based road network buffers, increasing proportion of institutional landsignificantly reduced the odds of 'walking for leisure 15 minutes or less per day' no significant resultswere found for circular buffers. A greater proportion of residential land significantly increased theodds of 'walking for errands less than 1 hour per week' for line-based road network buffer whileno significant results for circular buffers. An increased proportion of commercial land significantlydecreased the odds of 'walking for errands less than 1 hour per week' for both circular and linebasedroad network buffers.Conclusion: The selection of network or circular buffers has a considerable influence on theresults of analysis. Land use characteristics generally show greater associations with walking usingline-based road network buffers than circular buffers. These results show that researchers need tocarefully consider the most appropriate buffer with which to calculate land use characteristics.

Effects of Neighbourhood Income on Reported Body Mass Index: An Eight Year Longitudinal Study of Canadian Children

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2008
Abstract: 

Background:

This study investigates the effects of neighbourhood income on children's BodyMass Index (BMI) from childhood (ages 2–3) to early adolescence (ages 10–11) using longitudinaldata.

Methods:

Five cycles of data from the Canadian National Longitudinal Survey of Children andYouth are analyzed for a sub-sample of children (n = 2152) aged 2–3 at baseline (1994) and assessedat two year intervals to 2002. Body mass index percentiles are based on height/weight estimatesreported by proxy respondents (child's person most knowledgeable). Family and neighbourhoodfactors were assessed at baseline. The prevalence of neighbourhood low income was obtained fromthe 1996 Census and divided into three categories from 'most poor' to 'least poor'. Longitudinalmodelling techniques were applied to the data.

Results:

After controlling for individual/family factors (age, sex, income, education, familystructure) living in the 'most poor' neighbourhood was associated with increasing BMI percentile(1.46, 95% CI 0.16 to 2.75) over time compared to a 'middle' income neighbourhood. Living in anurban (vs. rural) neighbourhood was associated with a decreased BMI percentile (-3.57, 95% CI -6.38 to -0.76) across all time periods.

Conclusion:

These findings provide evidence that effects of neighbourhood disadvantage onchildren's BMI occur between childhood and early adolescence and suggest that policies shouldtarget the conditions of childhood, including the neighbourhood environment.

What is Known about the Effects of Medical Tourism in Destination and Departure Countries? A Scoping Review.

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2010
Abstract: 

Background:

Medical tourism involves patients intentionally leaving their home country to access non-emergencyhealth care services abroad. Growth in the popularity of this practice has resulted in a significant amount ofattention being given to it from researchers, policy-makers, and the media. Yet, there has been little effort tosystematically synthesize what is known about the effects of this phenomenon. This article presents the findings ofa scoping review examining what is known about the effects of medical tourism in destination and departurecountries.

Methods:

Drawing on academic articles, grey literature, and media sources extracted from18 databases, we followa widely used scoping review protocol to synthesize what is known about the effects of medical tourism indestination and departure countries. The review design has three main stages: (1) identifying the question andrelevant literature; (2) selecting the literature; and (3) charting, collating, and summarizing the data.

Results:

The large majority of the 203 sources accepted into the review offer a perspective of medical tourismfrom the Global North, focusing on the flow of patients from high income nations to lower and middle incomecountries. This greatly shapes any discussion of the effects of medical tourism on destination and departurecountries. Five interrelated themes that characterize existing discussion of the effects of this practice were extractedfrom the reviewed sources. These themes frame medical tourism as a: (1) user of public resources; (2) solution tohealth system problems; (3) revenue generating industry; (4) standard of care; and (5) source of inequity. It isobserved that what is currently known about the effects of medical tourism is minimal, unreliable, geographicallyrestricted and mostly based on speculation.

Conclusions:

Given its positive and negative effects on the health care systems of departure and destinationcountries, medical tourism is a highly significant and contested phenomenon. This is especially true given itspotential to serve as a powerful force for the inequitable delivery of health care services globally. It isrecommended that empirical evidence and other data associated with medical tourism be subjected to clear andcoherent definitions, including reports focused on the flows of medical tourists and surgery success rates.Additional primary research on the effects of medical tourism is needed if the industry is to develop in a mannerthat is beneficial to citizens of both departure and destination countries.

An Industry Perspective on Canadian Patients' Involvement in Medical Tourism: Implications for Public Health

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2011
Abstract: 

Background:

The medical tourism industry, which assists patients with accessing non-emergency medical careabroad, has grown rapidly in recent years. A lack of reliable data about medical tourism makes it difficult to createpolicy, health system, and public health responses to address the associated risks and shortcomings, such as spreadof infectious diseases, associated with this industry. This article addresses this knowledge gap by analyzinginterviews conducted with Canadian medical tourism facilitators in order to understand Canadian patients’involvement in medical tourism and the implications of this involvement for public health.

Methods:

Semi-structured phone interviews were conducted with 12 medical facilitators from 10 companies in2010. An exhaustive recruitment strategy was used to identify interviewees. Questions focused on businessdimensions, information exchange, medical tourists’ decision-making, and facilitators’ roles in medical tourism.Thematic analysis was undertaken following data collection.Results: Facilitators helped their Canadian clients travel to 11 different countries. Estimates of the number ofclients sent abroad annually varied due to demand factors. Facilitators commonly worked with medical touristsaged between 40 and 60 from a variety of socio-economic backgrounds who faced a number of potential barriersincluding affordability, fear of the unfamiliar, and lack of confidence. Medical tourists who chose not to usefacilitators’ services were thought to be interested in saving money or have cultural/familial connections to thedestination country. Canadian doctors were commonly identified as barriers to securing clients.

Conclusions:

No effective Canadian public health response to medical tourism can treat medical tourists as aunified group with similar motivations for engaging in medical tourism and choosing similar mechanisms fordoing so. This situation may be echoed in other countries with patients seeking care abroad. Therefore, a call for acomprehensive public health response to medical tourism and its effects should be coupled with a clearunderstanding that medical tourism is a highly diverse practice. This response must also acknowledge facilitators asimportant stakeholders in medical tourism.

Interpreting the Results of a Modified Gravity Model: Examining Access to Primary Health Care Physicians in Five Canadian Provinces and Territories

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2012
Abstract: 

Primary health care (PHC) encompasses an array of health and social services that focus onpreventative, diagnostic, and basic care measures to maintain wellbeing and address illnesses.In Canada, PHC involves the provision of first-contact health care services by providers suchas family physicians and general practitioners – collectively referred as PHC physicians here.Ensuring access is a key requirement of effective PHC delivery. This is because havingaccess to PHC has been shown to positively impact a number of health outcomes.MethodsWe build on recent innovations in measuring potential spatial access to PHC physicians usinggeographic information systems (GIS) by running and then interpreting the findings of amodified gravity model. Elsewhere we have introduced the protocol for this model. In thisarticle we run it for five selected Canadian provinces and territories. Our objectives are topresent the results of the modified gravity model in order to: (1) understand how potentialspatial access to PHC physicians can be interpreted in these Canadian jurisdictions, and (2)provide guidance regarding how findings of the modified gravity model should be interpretedin other analyses.ResultsRegarding the first objective, two distinct spatial patterns emerge regarding potential spatialaccess to PHC physicians in the five selected Canadian provinces: (1) a clear north–southpattern, where southern areas have greater potential spatial access than northern areas; and (2)while gradients of potential spatial access exist in and around urban areas, access outside ofdensely-to-moderately populated areas is fairly binary. Regarding the second objective, weidentify three principles that others can use to interpret the findings of the modified gravitymodel when used in other research contexts.

An Evaluation of Canada's Compassionate Care Benefit from a Family Caregiver's Perspective at End of Life

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2008
Abstract: 

Background: The goal of Canada's Compassionate Care Benefit (CCB) is to enable familymembers and other loved ones who are employed to take a temporary secured leave to care for aterminally ill individual at end of life. Successful applicants of the CCB can receive up to 55% of theiraverage insured earnings, up to a maximum of CDN$435 per week, over a six week period toprovide care for a gravely ill family member at risk of death within a six month period, as evidencedby a medical certificate. The goal of this study is to evaluate the CCB from the perspective of familycaregivers providing care to individuals at end of life. There are three specific research objectives.Meeting these objectives will address our study purpose which is to make policy-relevantrecommendations informed by the needs of Canadian family caregivers and input from other keystakeholders who shape program uptake. Being the first study that will capture family caregivers'experiences and perceptions of the CCB and gather contextual data with front-line palliative carepractitioners, employers, and human resources personnel, we will be in a unique position toprovide policy solutions/recommendations that will address concerns raised by numerousindividuals and organizations.Methods: We will achieve the research goal and objectives through employing utilization-focusedevaluation as our methodology, in-depth interviews and focus groups as our techniques of datacollection, and constant comparative as our technique of data analysis. Three respondent groupswill participate: (1) family caregivers who are providing or who have provided end of life care viaphone interview; (2) front-line palliative care practitioners via phone interview; and (3) humanresources personnel and employers via focus group. Each of these three groups has a stake in thesuccessful administration of the CCB. A watching brief of policy documents, grey literature, mediareports, and other relevant items will also be managed throughout data collection.Discussion: We propose to conduct this study over a three year period beginning in October,2006 and ending in October, 2009.

What Is Known About The Patient's Experience Of Medical Tourism? A Scoping Review

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2010
Abstract: 

Background: Medical tourism is understood as travel abroad with the intention of obtaining non-emergencymedical services. This practice is the subject of increasing interest, but little is known about its scope.Methods: A comprehensive scoping review of published academic articles, media sources, and grey literaturereports was performed to answer the question: what is known about the patient’s experience of medical tourism?The review was accomplished in three steps: (1) identifying the question and relevant literature; (2) selecting theliterature; (3) charting, collating, and summarizing the information. Overall themes were identified from this process.Results: 291 sources were identified for review from the databases searched, the majority of which were mediapieces (n = 176). A further 57 sources were included for review after hand searching reference lists. Of the 348sources that were gathered, 216 were ultimately included in this scoping review. Only a small minority of sourcesreported on empirical studies that involved the collection of primary data (n = 5). The four themes identified viathe review were: (1) decision-making (e.g., push and pull factors that operate to shape patients’ decisions); (2)motivations (e.g., procedure-, cost-, and travel-based factors motivating patients to seek care abroad); (3) risks (e.g.,health and travel risks); and (4) first-hand accounts (e.g., patients’ experiential accounts of having gone abroad formedical care). These themes represent the most discussed issues about the patient’s experience of medical tourismin the English-language academic, media, and grey literatures.Conclusions: This review demonstrates the need for additional research on numerous issues, including: (1)understanding how multiple information sources are consulted and evaluated by patients before deciding uponmedical tourism; (2) examining how patients understand the risks of care abroad; (3) gathering patients’prospective and retrospective accounts; and (4) the push and pull factors, as well as the motives of patients toparticipate in medical tourism. The findings from this scoping review and the knowledge gaps it uncovered alsodemonstrate that there is great potential for new contributions to our understanding of the patient’s experience ofmedical tourism.

Visioning For Secondary Palliative Care Service Hubs in Rural Communities: A Qualitative Case Study from British Columbia's Interior

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2009
Abstract: 

Background: As the populations of many developed nations continue to age at rapid rates it is becomingincreasingly important to enhance palliative care service delivery in order to meet anticipated demand. Rural areasface a number of challenges in doing this, and thus dedicated attention must be given to determining how to bestenhance service delivery in ways that are sensitive to their particular needs. The purposes of this article are todetermine the vision for establishing secondary palliative care service hubs (SPCH) in rural communities throughundertaking a case study, and to ascertain the criteria that need to be considered when siting such hubs.Methods: A rural region of British Columbia, Canada was selected for primary data collection, which took placeover a five-month period in 2008. Formal and informal palliative care providers (n = 31) were interviewed. Apurposeful recruitment strategy was used to maximize occupational and practice diversity. Interviews wereconducted by phone using a semi-structured guide. Interviews were audio recorded and transcribed verbatim.Data were managed using NVivo8™ software and analyzed thematically, using investigator triangulation tostrengthen interpretation.Results: Four themes emerged from the dataset: (1) main SPCH features; (2) determining a location; (3) valueaddedoutcomes; and (4) key considerations. It was found that participants generally supported implementing aSPCH in the rural region of focus. Several consistent messages emerged, including that: (1) SPCHs must createopportunities for two-way information exchange between specialists and generalists and communities; (2) SPCHsshould diffuse information and ideas throughout the region, thus serving as a locus for education and a means ofenhancing training opportunities; and (3) hubs need not be physical sites in the community (e.g., an office in ahospice or hospital), but may be virtual or take other forms based upon local needs.Conclusion: Visioning innovation in the provision of palliative care service in rural communities can be enhancedby consultation with local providers. Interviews are a means of determining local concerns and priorities. Therewas widespread support for SPCH coupled with some uncertainty about means of implementation.

Chronically Ill Canadians' Experiences of Being Unattached To a Family Doctor: A Qualitative Study of Marginalized Patients in British Columbia

Peer reviewed: 
Yes, item is peer reviewed.
Date created: 
2012
Abstract: 

Background: Unattached patients do not have a regular primary care provider. Initiatives are being developed toincrease attachment rates across Canada. Most existing attention paid to patient unattachment has focused onquantifying the problem and health system costs. Our purpose is to qualitatively identify the implications ofchronically ill patients’ experiences of unattachment for health policy and planning to provide policy-relevantinsights for Canadian attachment initiatives.Methods: Three focus groups were conducted with marginalized chronically ill individuals residing in a mid-sized city inBritish Columbia who are unattached to a family doctor. We use the term marginalized as a descriptor to acknowledgethat by virtue of their low socio-economic status and lack of attachment the participants are marginalized in Canada’shealth care system Focus groups were structured as an open conversation organized around a series of probingquestions. They were digitally recorded and transcribed verbatim. Thematic analysis was employed.Results: Twenty-six individuals participated in the focus groups. The most common chronic illnesses reported were activedrug addiction or recovery (and their associated symptoms), depression, arthritis, and hepatitis C. Participants identifiedlife transitions as being the root cause for not having a family doctor. There was a strong sense that unsuccessfulattempts to get a family doctor reflected that they were undesirable patients. Participants wanted to experience having atrusting relationship with a regular family doctor as they believed it would encourage greater honesty and transparency.One of the main health concerns regarding lack of access to a regular family doctor is that participants lacked access topreventative care. Participants were also concerned about having a discontinuous medical record due to unattachment.Conclusions: Participants perceived that there are many benefits to be had by having attachment to a regular familydoctor and that experiencing unattachment challenged their health and access to health care. We encourage moreresearch to be done on the lived experience of unattachment in order to provide on-the-ground insights thatpolicy-makers require in order to develop responsive, patient-centred supports and programs.
