Geographical clustering of prostate cancer grade and stage at diagnosis, before and after adjustment for risk factors
BACKGROUND: Spatial variation in patterns of disease outcomes is often explored with techniques such as cluster detection analysis. In other types of investigations, geographically varying individual or community level characteristics are often used as independent predictors in statistical models which also attempt to explain variation in disease outcomes. However, there is a lack of research which combines geographically referenced exploratory analysis with multilevel models. We used a spatial scan statistic approach, in combination with predicted block group-level disease patterns from multilevel models, to examine geographic variation in prostate cancer grade and stage at diagnosis. RESULTS: We examined data from 20928 Maryland men with incident prostate cancer reported to the Maryland Cancer Registry during 1992–1997. Initial cluster detection analyses, prior to adjustment, indicated that there were four statistically significant clusters of high and low rates of each outcome (later stage at diagnosis and higher histologic grade of tumor) for prostate cancer cases in Maryland during 1992–1997. After adjustment for individual case attributes, including age, race, year of diagnosis, patterns of clusters changed for both outcomes. Additional adjustment for Census block group and county-level socioeconomic measures changed the cluster patterns further. CONCLUSIONS: These findings provide evidence that, in locations where adjustment changed patterns of clusters, the adjustment factors may be contributing causes of the original clusters. In addition, clusters identified after adjusting for individual and area-level predictors indicate area of unexplained variation, and merit further small-area investigations
How does social integration influence breast cancer control among urban African-American women? Results from a cross-sectional survey
<p>Abstract</p> <p>Background</p> <p>Although social integration is a well-established influence on health, less is known about how the specific types of social connection (social roles, social networks, and social support) influence knowledge, attitudes, and practices for specific prevention goals, and how to utilize these influences in interventions with priority populations. This research examined the prevalence of social roles, networks and support among 576 urban African-American women age 45–93 in East Baltimore, Maryland, and the association of these social factors with breast cancer related knowledge, attitudes, and practices.</p> <p>Methods</p> <p>Using data from 1997–1998 in-home interviews, we developed indices of six possible social roles, social networks of family, neighborhood and church, and instrumental and emotional social support. In multivariate models adjusting for age, education, and medical care, we examined the association of each social influence on breast cancer knowledge, attitudes, screening recency and intention, and treatment preferences.</p> <p>Results</p> <p>We found substantial variation in social integration among these women, with social integration positively associated with overall health and well-being. Social roles and networks were positively associated with screening knowledge, and emotional support and church networks were positively associated with attitudes conducive to early detection and treatment. In regard to screening behaviors, family networks were associated with both screening recency and intention. Women with greater church networks and emotional support held more conservative attitudes towards lumpectomy, reconstruction, and clinical trials.</p> <p>Conclusion</p> <p>Overall, social integration is a positive influence on breast cancer control and should be utilized where possible in interventions, including identifying surrogate mechanisms for support for subgroups without existing social resources.</p
A healthy mistrust: how worldview relates to attitudes about breast cancer screening in a cross-sectional survey of low-income women
<p>Abstract</p> <p>Background</p> <p>Perceived racial discrimination is one factor which may discourage ethnic minorities from using healthcare. However, existing research only partially explains why some persons do accept health promotion messages and use preventive care, while others do not. This analysis explores 1) the psychosocial characteristics of those, within disadvantaged groups, who identify their previous experiences as racially discriminatory, 2) the extent to which perceived racism is associated with broader perspectives on societal racism and powerlessness, and 3) how these views relate to disadvantaged groups' expectation of mistreatment in healthcare, feelings of mistrust, and motivation to use care.</p> <p>Methods</p> <p>Using survey data from 576 African-American women, we explored the prevalence and predictors of beliefs and experiences related to social disengagement, racial discrimination, desired and actual racial concordance with medical providers, and fear of medical research. We then used both sociodemographic characteristics, and experiences and attitudes about disadvantage, to model respondents' scores on an index of personal motivation to receive breast cancer screening, measuring screening knowledge, rejection of fatalistic explanatory models of cancer, and belief in early detection, and in collaborative models of patient-provider responsibility.</p> <p>Results</p> <p>Age was associated with lower motivation to screen, as were depressive symptoms, anomie, and fear of medical research. Motivation was low among those more comfortable with African-American providers, regardless of current provider race. However, greater awareness of societal racism positively predicted motivation, as did talking to others when experiencing discrimination. Talking was most useful for women with depressive symptoms.</p> <p>Conclusion</p> <p>Supporting the Durkheimian concepts of both anomic and altruistic suicide, both disengagement (depression, anomie, vulnerability to victimization, and discomfort with non-Black physicians) as well as over-acceptance (low awareness of discrimination in society) predict poor health maintenance attitudes in disadvantaged women. Women who recognize their connection to other African-American women, and who talk about negative experiences, appear most motivated to protect their health.</p

Abstract available at publisher's website
A healthy mistrust: how worldview relates to attitudes about breast cancer screening in a cross-sectional survey of low-income women-1
N screening motivation is shown to be partially mediated by views on societal racism. In analysis 2, reported racism is partially mediated by the strategy of talking to others when experiencing unfair treatment. In analysis 3, the effect of anomie on screening motivation is partially mediated by preference for a Black physician.<p><b>Copyright information:</b></p><p>Taken from "A healthy mistrust: how worldview relates to attitudes about breast cancer screening in a cross-sectional survey of low-income women"</p><p>http://www.equityhealthj.com/content/7/1/5</p><p>International Journal for Equity in Health 2008;7():5-5.</p><p>Published online 31 Jan 2008</p><p>PMCID:PMC2267195.</p><p></p

Sustentabilidade corporativa e criação de valor: o caso “Dow Jones Sustainability Index”
Choosing an enterprise that will be part of Dow Jones Sustainability Index (DJSI) raises some expectations concerning this conquest benefits. We hope that the investment on sustainable development and the inclusion of the company in this select group bring economic and strategic benefits that can reflect in the company market valorization. However, the correlation between social, environmental and financial development is quite complex. In this context, this paper aims to verify whether the inclusion of an enterprise in DSJI list, which presupposes a high social and environmental performance, provides it with greater financial return. We use the case study method in order to investigate the existence of abnormal returns when disclosing the information of the company inclusion in the list, as well to analyze the hypothesis that market has positive expectations concerning to DSJI participation. This study included one hundred and fifty-four companies listed in DSJI that trade their shares on the New York Stock. The results show no effect and do not confirm the greater return hypothesis, but neither do they indicate a reduction in financial performance associated do this fact
