To measure the effectiveness of fluoride varnish (FV) (Duraflor), 5% sodium fluoride, Pharmascience Inc., Montréal, QC, Canada) and caregiver counseling in preventing early childhood caries (ECC) in Aboriginal children in a 2-year community-randomized controlled trial.
Twenty First Nations communities in the Sioux Lookout Zone (SLZ), Northwest Ontario, Canada were randomized to two study groups. All caregivers received oral health counseling, while children in one group received FV twice per year and the controls received no varnish. A total of 1275, 6 months to 5-year-old children from the SLZ communities were enrolled. In addition, a convenience sample of 150 primarily non-Aboriginal children of the same age were recruited from the neighboring community of Thunder Bay and used as comparisons. Longitudinal examinations for the dmft/s indices were conducted by calibrated hygienists in 2003, 2004 and 2005.
Aboriginal children living in the SLZ or in Thunder Bay had significantly higher caries prevalence and severity than non-Aboriginal children in Thunder Bay. FV treatment conferred an 18% reduction in the 2-year mean 'net' dmfs increment for Aboriginal children and a 25% reduction for all children, using cluster analysis to adjust for the intra-cluster correlation among children in the same community. Adjusted odds ratio for caries incidence was 1.96 times higher in the controls than in the FV group (95% CI = 1.08-3.56; P = 0.027). For those caries-free at baseline, the number (of children) needed to treat (NNT) equaled 7.4.
Findings support the use of FV at least twice per year, in conjunction with caregiver counseling, to prevent ECC, reduce caries increment and oral health inequalities between young Aboriginal and non-Aboriginal children.
The introduction of second-generation antipsychotic drugs during the 1990s is widely believed to have adversely affected mortality of patients with schizophrenia. Our aim was to establish the long-term contribution of antipsychotic drugs to mortality in such patients.
Nationwide registers in Finland were used to compare the cause-specific mortality in 66 881 patients versus the total population (5.2 million) between 1996, and 2006, and to link these data with the use of antipsychotic drugs. We measured the all-cause mortality of patients with schizophrenia in outpatient care during current and cumulative exposure to any antipsychotic drug versus no use of these drugs, and exposure to the six most frequently used antipsychotic drugs compared with perphenazine use.
Although the proportional use of second-generation antipsychotic drugs rose from 13% to 64% during follow-up, the gap in life expectancy between patients with schizophrenia and the general population did not widen between 1996 (25 years), and 2006 (22.5 years). Compared with current use of perphenazine, the highest risk for overall mortality was recorded for quetiapine (adjusted hazard ratio [HR] 1.41, 95% CI 1.09-1.82), and the lowest risk for clozapine (0.74, 0.60-0.91; p=0.0045 for the difference between clozapine vs perphenazine, and p

Long-term measures to reduce tobacco consumption in Australia have had differential effects in the population. The prevalence of smoking in Aboriginal peoples is currently more than double that of the non-Aboriginal population. Aboriginal Health Workers are responsible for providing primary health care to Aboriginal clients including smoking cessation programs. However, Aboriginal Health Workers are frequently smokers themselves, and their smoking undermines the smoking cessation services they deliver to Aboriginal clients. An understanding of the barriers to quitting smoking experienced by Aboriginal Health Workers is needed to design culturally relevant smoking cessation programs. Once smoking is reduced in Aboriginal Health Workers, they may then be able to support Aboriginal clients to quit smoking.
We undertook a fundamental qualitative description study underpinned by social ecological theory. The research was participatory, and academic researchers worked in partnership with personnel from the local Aboriginal health council. The barriers Aboriginal Health Workers experience in relation to quitting smoking were explored in 34 semi-structured interviews (with 23 Aboriginal Health Workers and 11 other health staff) and 3 focus groups (n = 17 participants) with key informants. Content analysis was performed on transcribed text and interview notes.
Aboriginal Health Workers spoke of burdensome stress and grief which made them unable to prioritise quitting smoking. They lacked knowledge about quitting and access to culturally relevant quitting resources. Interpersonal obstacles included a social pressure to smoke, social exclusion when quitting, and few role models. In many workplaces, smoking was part of organisational culture and there were challenges to implementation of Smokefree policy. Respondents identified inadequate funding of tobacco programs and a lack of Smokefree public spaces as policy level barriers. The normalisation of smoking in Aboriginal society was an overarching challenge to quitting.
Aboriginal Health Workers experience multilevel barriers to quitting smoking that include personal, social, cultural and environmental factors. Multidimensional smoking cessation programs are needed that reduce the stress and burden for Aboriginal Health Workers; provide access to culturally relevant quitting resources; and address the prevailing normalisation of smoking in the family, workplace and community.

For demographic reasons and as a result of a number of high profile health incidents in recent years, much of the health research and policy focus is on the younger cohorts of Aboriginal peoples in Canada. A critical examination of recent demographic trends reveals, however, that older cohorts of the Aboriginal population are increasing at a faster rate than younger cohorts, primarily due to improvements in life expectancy and declining fertility rates. Yet, there are surprisingly few health studies that have recognized the aging of the Aboriginal population. The overall goal of this paper is to examine differences in health status, use of conventional health care and traditional approaches to healing between older and younger cohorts of the Aboriginal population as well as to examine the importance of age as a determinant of health and health care use. Using data from the 2001 Statistics Canada Aboriginal Peoples Survey and contingency tables and logistic regression, the results demonstrate that older Aboriginal people face unique challenges - e.g. loss of traditional approaches to healing, geographic isolation, identity politics, constitutional and legal divisions within the Aboriginal community - with respect to their health and access to health services. These outcomes result from a colonial past and contemporary policies that affect all Aboriginal people.
Urbanization among Indigenous peoples is growing globally. This has implications for the assertion of Indigenous rights in urban areas, as rights are largely tied to land bases that generally lie outside of urban areas. Through their impacts on the broader social determinants of health, the links between Indigenous rights and urbanization may be related to health. Focusing on a Canadian example, this study explores relationships between Indigenous rights and urbanization, and the ways in which they are implicated in the health of urban Indigenous peoples living in Toronto, Canada. In-depth interviews focused on conceptions of and access to Aboriginal rights in the city, and perceived links with health, were conduced with 36 Aboriginal people who had moved to Toronto from a rural/reserve area. Participants conceived of Aboriginal rights largely as the rights to specific services/benefits and to respect for Aboriginal cultures/identities. There was a widespread perception among participants that these rights are not respected in Canada, and that this is heightened when living in an urban area. Disrespect for Aboriginal rights was perceived to negatively impact health by way of social determinants of health (e.g., psychosocial health impacts of discrimination experienced in Toronto). The paper discusses the results in the context of policy implications and future areas of research.
Poor academic achievement is strongly related to smoking but studies that examine the mechanism between academic achievement and smoking are lacking. The aim of this study, therefore, was to examine the smoking-related cognitions (i.e. attitude, social influence, self-efficacy and intention to smoke) in relation to academic achievement and determine whether these cognitions explain different patterns of smoking.
The study uses the data of a longitudinal study that was carried out in Finland, and the sample comprised 1,096 students in grades seven to nine.
During the seventh-grade students with poor academic achievement reported more positive attitudes to smoking and a greater social influence of their peers regarding smoking, weaker self-efficacy to refuse smoking and more intentions to smoke in the future compared to students with high academic achievement. Moreover, the follow-up analyses after a 24-month interval revealed that self-efficacy to refuse smoking of students with poor grades had become weaker compared to students with high grades. Furthermore, the influence of seventh-grade academic achievement predicting ninth-grade weekly smoking was partially mediated through the self-efficacy beliefs and the intention to smoke.
Differences in academic achievement may have an impact on adolescents' self-efficacy beliefs and the intention to smoke in the future. To reduce health inequalities a strong input on continuing research to improve smoking prevention methods, especially for students with low academic achievement, is needed.
In this article, we discuss findings from an ethnographic study in which we explored experiences of access to primary care services from the perspective of Aboriginal people seeking care at an emergency department (ED) located in a large Canadian city. Data were collected over 20 months of immersion in the ED, and included participant observation and in-depth interviews with 44 patients triaged as stable and nonurgent, most of whom were living in poverty and residing in the inner city. Three themes in the findings are discussed: (a) anticipating providers' assumptions; (b) seeking help for chronic pain; and (c) use of the ED as a reflection of social suffering. Implications of these findings are discussed in relation to the role of the ED as well as the broader primary care sector in responding to the needs of patients affected by poverty, racialization, and other forms of disadvantage.
Despite experiencing a disproportionate burden of acute and chronic health issues, many homeless people face barriers to primary health care. Most studies on health care access among homeless populations have been conducted in the United States, and relatively few are available from countries such as Canada that have a system of universal health insurance. We investigated access to primary health care among a representative sample of homeless adults in Toronto, Canada.
Homeless adults were recruited from shelter and meal programs in downtown Toronto between November 2006 and February 2007. Cross-sectional data were collected on demographic characteristics, health status, health determinants and access to health care. We used multivariable logistic regression analysis to investigate the association between having a family doctor as the usual source of health care (an indicator of access to primary care) and health status, proof of health insurance, and substance use after adjustment for demographic characteristics.
Of the 366 participants included in our study, 156 (43%) reported having a family doctor. After adjustment for potential confounders and covariates, we found that the odds of having a family doctor significantly decreased with every additional year spent homeless in the participant's lifetime (adjusted odds ratio [OR] 0.91, 95% confidence interval [CI] 0.86-0.97). Having a family doctor was significantly associated with being lesbian, gay, bisexual or transgendered (adjusted OR 2.70, 95% CI 1.04-7.00), having a health card (proof of health insurance coverage in the province of Ontario) (adjusted OR 2.80, 95% CI 1.61-4.89) and having a chronic medical condition (adjusted OR 1.91, 95% CI 1.03-3.53).
Less than half of the homeless people in Toronto who participated in our study reported having a family doctor. Not having a family doctor was associated with key indicators of health care access and health status, including increasing duration of homelessness, lack of proof of health insurance coverage and having a chronic medical condition. Increased efforts are needed to address the barriers to appropriate health care and good health that persist in this population despite the provision of health insurance.
The public health care systems in the Nordic countries provide high quality care almost free of charge to all citizens. However, social inequalities in health persist. Previous research has, for example, documented substantial educational inequalities in cancer survival. We investigate to what extent this may be driven by differential access to and utilization of high quality treatment options. Quasi-experimental evidence based on the establishment of regional cancer wards indicates that (i) highly educated individuals utilized centralized specialized treatment to a greater extent than less educated patients and (ii) the use of such treatment improved these patients' survival.
