Social space, social class and Bourdieu: health inequalities in British Columbia, Canada

This article adopts Pierre Bourdieu's cultural-structuralist approach to conceptualizing and identifying social classes in social space and seeks to identify health effects of class in one Canadian province. Utilizing data from an original questionnaire survey of randomly selected adults from 25 communities in British Columbia, social (class) groupings defined by cultural tastes and dispositions, lifestyle practices, social background, educational capital, economic capital, social capital and occupational categories are presented in visual mappings of social space constructed by use of exploratory multiple correspondence analysis techniques. Indicators of physical and mental health are then situated within this social space, enabling speculations pertaining to health effects of social class in British Columbia.     

The contextual effects of social capital on health: A cross-national instrumental variable analysis

Past research on the associations between area-level/contextual social capital and health has produced conflicting evidence. However, interpreting this rapidly growing literature is difficult because estimates using conventional regression are prone to major sources of bias including residual confounding and reverse causation. Instrumental variable (IV) analysis can reduce such bias. Using data on up to 167 344 adults in 64 nations in the European and World Values Surveys and applying IV and ordinary least squares (OLS) regression, we estimated the contextual effects of country-level social trust on individual self-rated health. We further explored whether these associations varied by gender and individual levels of trust. Using OLS regression, we found higher average country-level trust to be associated with better self-rated health in both women and men. Instrumental variable analysis yielded qualitatively similar results, although the estimates were more than double in size in both sexes when country population density and corruption were used as instruments. The estimated health effects of raising the percentage of a country’s population that trusts others by 10 percentage points were at least as large as the estimated health effects of an individual developing trust in others. These findings were robust to alternative model specifications and instruments. Conventional regression and to a lesser extent IV analysis suggested that these associations are more salient in women and in women reporting social trust. In a large cross-national study, our findings, including those using instrumental variables, support the presence of beneficial effects of higher country-level trust on self-rated health. Previous findings for contextual social capital using traditional regression may have underestimated the true associations. Given the close linkages between self-rated health and all-cause mortality, the public health gains from raising social capital within and across countries may be large.

Income inequality and health. Coastal communities in British Columbia,Canada

OBJECTIVE: An imbalance in the distribution of economic resources, i.e., income inequality, is a characteristic of a community that may influence the aggregate health of the population. In North America, income inequality seems to be strongly related to mortality rates among American communities such as states and metropolitan areas but largely irrelevant for health at similar levels of geopolitical aggregation in Canada. This article summarizes relevant international and North American evidence and then explores relationships between income inequality and mortality rates among coastal communities in the province of British Columbia, Canada. METHODS: Cross-sectional analysis was conducted among twenty-four coastal communities in British Columbia, utilizing four measures based on the 1996 Census to measure income inequality and crude, age-standardized and age- and gender-specific mortality rates averaged over the five-year period 1994-98 to measure health. RESULTS: The three valid measures of income inequality were positively and significantly related to the crude mortality rate but were not significantly related to the age-standardized mortality rate. Two of the inequality measures were related to mortality rates for males aged 0-44 and for males aged 45-64 before but not after controlling for mean household income. DISCUSSION: Health researchers have yet to report a meaningful relationship between income inequality and population health within Canada. At the risk of committing the ecological fallacy, these findings provisionally support a psycho-social interpretation of the individual-level relationship between income and health wherein members of these communities compare themselves to an encompassing community, e.g., all Canadians.     

Drug formulary decision-making in two regional health authorities in British Columbia, Canada

OBJECTIVES: Growing pharmaceutical demands challenge healthcare organizations to set drug funding priorities (i.e. establish a formulary list). This responsibility typically rests with pharmacy and therapeutics (P&T) committees, yet how the process transpires within regional health authorities is unclear. The purpose of this study was to construct an explanatory model of drug formulary priority-setting as it occurs within regional health authorities. METHODS: A grounded theory approach was employed to study the practices of two regional health authority P&T committees in British Columbia, Canada. Data sources spanned committee documents, meeting observations (n=4), and semi-structured interviews with committee members (n=15). Data analysis involved coding using the constant comparative technique and writing analytic memos. RESULTS: Regional P&T committees engaged in two activities related to drug formulary priority-setting: developing auto-substitution policies and reviewing drug addition requests. Four processes were central to decision-making: (i) negotiating margins of therapeutic advantage; (ii) seeking value for the resources allocated; (iii) interfacing between community and institutional settings; (iv) situating decisions within an organizational context. CONCLUSIONS: Findings highlight opportunities for institutions to improve the fairness of agenda-setting practices, and for additional collaboration between policy-makers who prioritize drugs for publicly funded formularies applicable to institutional versus community settings.

Economy, community and mortality in British Columbia, Canada

Stimulated by the growing body of literature relating economic inequalities to inequalities in health, this article explores relationships between various economic attributes of communities and mortality rates among 24 coastal communities in British Columbia, Canada. Average household income, a measure of community wealth, was negatively related and the incidence of low incomes, a measure of poverty, was positively related to age-standardized mortality. Both were more strongly related to female than male mortality. Mean and median household income, the incidence of low incomes and a lack of disposable income, and the proportion of total income dollars derived from government sources were significantly related to mortality rates for younger and middle-aged men but not for elderly men. Mortality rates for younger and middle-aged women were not explicated by these economic attributes of communities: among elderly women only, mortality rates were higher in communities with a lower average household income and in those with a higher incidence of low incomes. Finally, a higher concentration in white-collar industries was related to higher mortality rates for females, even after controlling for other economic attributes of communities. These results do not obviously support a psychosocial argument for an individual-level relationship between income and health that assumes residents perceive their status primarily in relation to other members of the same community, but do provide moderate support for the materialist argument and moderate support for the psychosocial argument that assumes community residents perceive their status in relation to an encompassing reference group. Other viable interpretations of these relationships pertain to ecological characteristics of communities that are related to both economic well-being and population health status; in this instance, concentration in specific economic industries may help to understand the ecological relationships presented here.     

Cryptococcus gattii dispersal mechanisms, British Columbia, Canada

Recent Cryptococcus gattii infections in humans and animals without travel history to Vancouver Island, as well as environmental isolations of the organism in other areas of the Pacific Northwest, led to an investigation of potential dispersal mechanisms. Longitudinal analysis of C. gattii presence in trees and soil showed patterns of permanent, intermittent, and transient colonization, reflecting C. gattii population dynamics once the pathogen is introduced to a new site. Systematic sampling showed C. gattii was associated with high-traffic locations. In addition, C. gattii was isolated from the wheel wells of vehicles on Vancouver Island and the mainland and on footwear, consistent with anthropogenic dispersal of the organism. Increased levels of airborne C. gattii were detected during forestry and municipal activities such as wood chipping, the byproducts of which are frequently used in park landscaping. C. gattii dispersal by these mechanisms may be a useful model for other emerging pathogens.     

A population-based analysis of life satisfaction and social support among children of diverse backgrounds in British Columbia,Canada

Purpose

The Satisfaction With Life Scale adapted for Children (SWLS-C) is a self-report measure of children’s quality of life and has exhibited sound psychometric properties. In light of increasing ethno-cultural diversity, it is important to understand child life satisfaction across diverse subgroups. Employing children’s language background as a proxy for cultural background among children in British Columbia, Canada, we examined (a) the cross-cultural measurement equivalence of the SWLS-C; and (b) cross-cultural relations of peer support and adult support with SWLS-C.

Methods

Participants were 20,119 children (M_age 9.2; 50.2% boys) who provided data as part of a self-report child health survey (the Middle-years Development Instrument). Measurement equivalence across eight language/cultural background groups was tested via multi-group confirmatory factor analysis. Multi-level analyses were used to compare: a) SWLS-C means; and b) associations of peer support and adult support with SWLS-C scores, by language/cultural background.

Results

Findings supported strict measurement equivalence between the English language/cultural background group and all other language/cultural background groups for the SWLS-C. Relative to the English language background group, SWLS-C means differed for several language/cultural background groups. Within every language/cultural background group, however, peer and adult support scale scores were significant positive correlates of SWLS-C scores.

Conclusions

This study provided evidence for measurement equivalence of a life satisfaction measure across children from diverse language/cultural backgrounds and identified between-group differences in the level of child life satisfaction that were generally consistent with prior theory and findings. Moreover, results provided evidence of promotive associations of adult support and peer support with life satisfaction among diverse groups of children.

     

Salmonella enterica Serovar Agbeni, British Columbia, Canada, 2011

TO THE EDITOR: Infection with Salmonella enterica serovar Agbeni is rare. In Canada, it was reported 8 times during 2000-2010 and never in the province of British Columbia (2011 population?4.5 million) (Public Health Agency of Canada, unpub. data). In June 2011, an outbreak of S. enterica ser. Agbeni affecting 8 persons was identified in British Columbia; pulsed-field gel electrophoresis patterns for all isolates were identical. Although no specific source was identified, 2 features were noted: 1) diagnosis through urine specimens for 3 of 8 persons and 2) a longer than typical incubation period for Salmonella spp. infection.     

HCV co-infection in HIV positive population in British Columbia,Canada

Background  

As HIV and hepatitis C (HCV) share some modes of transmission co-infection is not uncommon. This study used a population-based sample of HIV and HCV tested individuals to determine the prevalence of HIV/HCV co-infection, the sequence of virus diagnoses, and demographic and associated risk factors.     

Work-related injury among direct care occupations in British Columbia, Canada

Objectives

To examine how injury rates and injury types differ across direct care occupations in relation to the healthcare settings in British Columbia, Canada.

Methods

Data were derived from a standardised operational database in three BC health regions. Injury rates were defined as the number of injuries per 100 full‐time equivalent (FTE) positions. Poisson regression, with Generalised Estimating Equations, was used to determine injury risks associated with direct care occupations (registered nurses [RNs], licensed practical nurses [LPNs) and care aides [CAs]) by healthcare setting (acute care, nursing homes and community care).

Results

CAs had higher injury rates in every setting, with the highest rate in nursing homes (37.0 injuries per 100 FTE). LPNs had higher injury rates (30.0) within acute care than within nursing homes. Few LPNs worked in community care. For RNs, the highest injury rates (21.9) occurred in acute care, but their highest (13.0) musculoskeletal injury (MSI) rate occurred in nursing homes. MSIs comprised the largest proportion of total injuries in all occupations. In both acute care and nursing homes, CAs had twice the MSI risk of RNs. Across all settings, puncture injuries were more predominant for RNs (21.3% of their total injuries) compared with LPNs (14.4%) and CAs (3.7%). Skin, eye and respiratory irritation injuries comprised a larger proportion of total injuries for RNs (11.1%) than for LPNs (7.2%) and CAs (5.1%).

Conclusions

Direct care occupations have different risks of occupational injuries based on the particular tasks and roles they fulfil within each healthcare setting. CAs are the most vulnerable for sustaining MSIs since their job mostly entails transferring and repositioning tasks during patient/resident/client care. Strategies should focus on prevention of MSIs for all occupations as well as target puncture and irritation injuries for RNs and LPNs.Direct care occupations comprise the largest proportion (58%) of healthcare employees in Canada and consist of registered nurses (RNs), licensed practical nurses (LPNs) and care aides (CAs).^1,2,3 Engkvist et al. (1998) describe a similar grouping of nursing occupations in Sweden with general RNs, state registered nurses (LPNs) and auxiliary nurses (CAs).⁴ Such employees work in various settings (acute care, nursing homes and community care) across the healthcare system. These settings, providing care specific to the needs of patients/residents/clients, have very differing task requirements. Due to shortages in the direct care occupations, workers have more opportunities to choose where they prefer to work. While wage differentials may influence recruitment and retention, as Spetz (2003) has noted, wage increases are not viable solutions for resolving the workforce shortages; work conditions were more important for recruiting and retaining personnel.⁵ Thus a study of differential risk of injuries for the various direct care occupations in different health settings is warranted.RNs can work as independent practitioners in all settings or as team members that assign clients and/or client care functions appropriately. LPNs do not work in isolation but as team members and must exercise clinical judgment in accepting assigned client care functions within their own level of competence.⁶ In many nursing homes, LPNs have been used interchangeably with CAs. CAs must work with the support of RNs and LPNs in providing help to patients/residents/clients with their activities of daily living (such as assistance with personal hygiene, dressing, eating and mobility). This often involves lifting, transferring and repositioning of patients/residents/clients.In the health sector across Canada in 2004, 62.5% of RNs were working in acute care, whereas 13.4% were working in community health and 10.5% in nursing homes.⁷ Jansen et al. (2000) reports that LPNs were predominantly (57%) in acute care, 33% in nursing homes and 10% in community care.⁸ CAs were predominantly working in nursing homes with some in community care and a smaller proportion in acute care.⁹ In the future, it is likely that more nurses will be required to work in nursing homes or community care because of policy changes that focus on reducing the number of chronic care residents in acute care settings, and an ageing population who will need ongoing care whether in their home, assisted living or nursing homes. RNs and LPNs may choose not to work in these settings if they perceive these work environments have higher injury risks than acute care.Changes in the nature of care provided to patients/residents/clients and shifts in work patterns have a great impact on the nursing profession.¹⁰ Because of the different tasks and roles for the three nursing occupations within different care settings, each nursing occupation may have different injury experiences.^8,11,12 Identifying these different patterns of injury through subgroup analysis by care types may allow for more effective targeting of prevention efforts, as well as help nursing staff make informed decisions. The aim of the present study was to examine how injury characteristics and incidence among the three nursing occupations differ in relation to acute care, nursing homes and community care settings in British Columbia (BC), Canada. Time‐at‐risk data can provide more accurate injury rates than general rates published by Workers'' Compensation Boards in Canada and the USA.     

Support for a vaccination documentation mandate in British Columbia,Canada

BackgroundIn recent years, Canadian provinces have been discussing, implementing, and tightening vaccination “mandate” policies for school enrolment. British Columbia (BC), Canada’s westernmost province, implemented a Vaccination Status Reporting Regulation (VSRR) in September 2019, which requires the vaccination status of children in public, private, and home schooling be reported to a provincial vaccination registry and education for parents who refuse to vaccinate. Legal vaccination mandates can carry the risk of backlash, thereby making it important to monitor public attitudes across policy implementation windows. The present study aimed to evaluate public support for this new provincial mandate following implementation.MethodsAn online panel of BC adults (n = 1301) was surveyed about 15 vaccine-promotion policy options in April 2020 following mandate implementation. Respondents were representative of the provincial population by gender, age, geographic residence, and percentage of households with children younger than 19 years of age. Poisson regression was used to estimate predictors of policy endorsement, and support for the VSRR.ResultsStrong support existed for the VSRR with 88.2% of respondents agreeing or strongly agreeing that parents should be required to provide their children’s immunization records at school entry, and 74.6% supporting required education sessions for parents who refuse to vaccinate their children. Overall, the sample was supportive of vaccination, and pro-vaccine attitudes were associated with strong agreement for nearly all vaccine policy options. Policies to impose rewards (e.g., tax credits) and penalties (e.g., fines) were the least likely to receive strong agreement from respondents.ConclusionsNear the end of the first school year in British Columbia subject to the Vaccination Status Reporting Regulation, support for both the mandated documentation and mandated education elements of the policy are high, and associated with pro-vaccine attitudes. There are not marked differences in strong support based on gender, age, parenting, education level, or income.
