The dynamics of the relationship between diabetes incidence and low income: longitudinal results from Canada's National Population Health Survey.

UNLABELLED: This paper sheds light on the dynamic relationship between people's experiences of low income and the development of type 2 diabetes (T2DM) by moving beyond the static perspective provided by cross-sectional studies to a long-term approach informed by longitudinal analyses. METHODS: We analyzed data from the Canadian National Population Health Survey (NPHS) conducted by Statistics Canada from 1994 to 2007. The longitudinal sample is composed of 17,276 respondents (8046 males, 9230 females) 12 years of age or older. We further developed an algorithm to distinguish T2DM from other types of diabetes. Proportional hazard models with time-varying predictors were used to explore the dynamics of the relationship between low income and T2DM. RESULTS: The results suggest that living in low income and experiencing persistent low income are significant precursors of developing T2DM. Being in low income in the previous cycle of T2DM onset was associated with 77% higher risk of T2DM (hazard ratio 1.77; 95% CI: 1.48-2.12). The association between low income and diabetes incidence remains significant after adjusting for age, sex, health behaviors, and psychological distress (hazard ratio 1.24; 95% CI: 1.02-1.52). CONCLUSION: This study contributes to the under-developed research examining longitudinally the relationship between socioeconomic status and diabetes incidence. Employing this long-term approach, this study calls attention to the primary effect of socioeconomic position on diabetes incidence that cannot be explained entirely by behavioral factors. Findings draw attention to the need to address the role played in T2DM by the inequitable distribution of the social determinants of health.

Diabetes prevalence and income: Results of the Canadian Community Health Survey.

UNLABELLED: This paper contributes to a growing body of literature indicating the importance of income as a key socioeconomic status marker in accounting for the increased prevalence of type 2 diabetes (T2DM). METHODS: We analyzed data from the Canadian Community Health Survey cycle 3.1 conducted by Statistics Canada. Descriptive statistics on the prevalence of self-reported diabetes were computed. Multiple logistic regression was used to examine the association between income and prevalence of T2DM. RESULTS: In 2005 an estimated 1.3 million Canadians (4.9%) reported having diabetes. The prevalence of T2DM in the lowest income group is 4.14 times higher than in the highest income group. Prevalence of diabetes decreases steadily as income goes up. The likelihood of diabetes was significantly higher for low-income groups even after adjusting for socio-demographic status, housing, BMI and physical activity. There is a graded association between income and diabetes with odds ratios almost double for men (OR 1.94, 95% CI 1.57-2.39) and almost triple for women (OR 2.75 95% CI 2.24-3.37) in the lowest income compared to those in highest income. CONCLUSION: These findings suggest that strategies for diabetes prevention should combine person-centered approaches generally recommended in the diabetes literature research with public policy approaches that acknowledge the role of socioeconomic position in shaping T2DM prevalence/incidence.

Type 2 diabetes in vulnerable populations: community healthcare providers' perspectives on health service needs and policy implications.

OBJECTIVES: To identify a) ways of enhancing health services for vulnerable populations with type 2 diabetes, taking into account the social determinants of health; and b) health and social policy approaches to reducing the incidence of type 2 diabetes and improving its management. METHODS: Focus groups were held with 18 community healthcare providers at 3 community health centres in Toronto, Ontario. RESULTS: Community healthcare providers' perspectives were organized under 3 themes: a) the compounding effects of social factors on the health of people with diabetes; b) the need for responsive support at multiple levels; and c) barriers to change. Participants showed a good understanding of the impact of social determinants of health on patients' lives, and they had many ideas about prevention/ health promotion and strategies to enhance health services. They seemed less aware of the important role that political advocacy can play. CONCLUSION: Assessment of the policy environment and political advocacy through coalition-building with communities and other health and social sector service providers should become part of healthcare professionals' education and responsibility. Adequate income and access to proper resources would help with the prevention and optimal management of diabetes.

An expanded model of diabetes care based in an analysis and critique of current approaches.

AIMS AND OBJECTIVES: To examine and critique various models guiding the care and education of people with diabetes, to develop more helpful and effective approaches to care. The focus is on relationships and communication between patients and healthcare providers. BACKGROUND: Many patients are not adhering to the recommended treatments, hence it seems that effective diabetes care is difficult to achieve, particularly for patients of lower socio-economic status, who are disproportionately afflicted. The results are usually devastating, and lead to serious health complications that incisively diminish quality of life for patients with diabetes, frustrate healthcare providers and increase healthcare costs. DESIGN: Critical review. METHOD: This paper represents a critical review of various approaches to diabetes care and education. A CINAHL search with relevant key words was carried out and selected exemplary research studies and articles describing and/or evaluating the various approaches to diabetes care and management were examined. Particular attention was paid to how the paradigmatic underpinnings of these approaches construct patient - healthcare provider relationships. CONCLUSION: The literature revealed that the traditional top-down approaches to care were largely ineffective, while collaborative approaches, based in respect and taking the whole persons and their unique situations into account, were found to be central to good care. Further, an integration of the different kinds of knowledge contained in the various approaches can complement and extend one another. RELEVANCE TO CLINICAL PRACTICE: Avoiding devastating complications by improving the management of diabetes and overall quality of life of patients is a worthwhile goal. Therefore expanding diabetes care beyond the traditional bio-medical model to develop more effective approaches to care is of interest to all healthcare professionals working in this area.

Perspectives of homeless people on their health and health needs priorities.

AIM: This paper is a report of a study of the perspectives of homeless individuals on their health and healthcare needs. BACKGROUND: Many studies show the high incidence and severity of diseases, physical and mental, amongst the homeless populations. However, the views of homeless people themselves are usually omitted. In order to provide appropriate care, healthcare professionals need to be aware of these perspectives. METHOD: A descriptive, exploratory design, using semi-structured interviews and observational field notes, was chosen for this qualitative study. A convenience sample of 24 participants experiencing homelessness was recruited in one Canadian city in 2005. FINDINGS: Participants described their health and healthcare needs in a holistic sense. They reported concerns about physical illnesses, mental health, addictions and stress. Shelter life promoted spread of diseases and lacked privacy. Violence was rampant in shelters and on the streets, leading to constant fear. There was emotional distress over social exclusion and depersonalization. Participants wanted to work and to be housed, yet felt trapped in a dehumanizing system. CONCLUSION: The recommendations are (a) elimination or mitigation of most health problems of the homeless through safe, affordable housing; (b) reintegration into the community through job counselling, treatment of addictions and employment. Negative societal attitudes towards these clients need to change. Healthcare professionals, particularly community nurses, have opportunities to collaborate respectfully with these clients and work for changes in public policies, such as national housing and addiction treatment policies, and for streamlined, humanized services to smooth the processes of social reintegration.

The health bus: healthcare for marginalized populations.

The Health Bus, an innovative outreach program, serves the marginalized population of a large Canadian city. In this article, a needs assessment/evaluation study of its services is discussed. Barriers to mainstream healthcare and solutions are examined. This study was qualitative, descriptive, and exploratory and surveyed 58 client volunteers of the program through semistructured interviews and focus groups. Thematic analysis of data was carried out. The Health Bus was found to provide basic healthcare and supplies effectively. Clients value respectful treatment, competency of healthcare professionals, and accessibility, whereas disrespectful treatments and lack of transportation are barriers to mainstream healthcare. A conclusion of this study is that Health Bus services should be expanded with clients' input. Mainstream institutions need flexibility and a change in attitudes toward the marginalized.

Changing nurses' dis-empowering relationship patterns.

BACKGROUND: Nurses' inter- and intra-disciplinary relationships are frequently interpreted as oppressed group behaviours, contributing to their relatively dis-empowered status. In the context of restructuring in health care, this study examined the views of hospital staff nurses about their relationships with nursing colleagues and other health care professionals and their ideas for change. AIM: The aim of this paper is to report a study to add the views of staff nurses to the discourse on restructuring and to make visible the processes that contribute to their marginalization. DESIGN: The study was descriptive and exploratory. Staff nurses from various hospitals in a large Canadian city were selected by theoretical sampling. METHOD: Twenty volunteer staff nurses were interviewed between 1998 and 1999, using broad, open-ended questions and prompts to explore nurses' various relationships in the health care system. This approach allowed for multiple responses and expansions of ideas, without losing focus. The interviews were audio-taped and later transcribed. Thematic analysis was carried out. FINDINGS: Many participants were aware of inter-disciplinary hierarchies, particularly between nurses and physicians. Many also showed insights into their own intra-disciplinary hierarchies and mutual non-supportiveness. Both types of relationships were found to be inextricably linked, sustaining nurses' oppression through dis-empowering discourses. Nurses expressed many ideas about how to promote mutually supportive relationships. CONCLUSION: Change for the better needs to come from within the nursing profession. To develop effective strategies, bedside nurses have to be included in decision-making processes affecting them and their practice, about which they are the experts. Mutual respect, awareness-raising through education, development of caring nursing communities, mentorship and non-hierarchical leadership are key to stopping dis-empowering discourses and practices amongst nurses.
