Perceived risk for breast cancer and its relationship to mammography in Blacks, Hispanics, and Whites.

A challenge for health behavior science is to develop theory and best practices that take cultural diversity into account. Using data from Black, Hispanic, and White respondents to the 2003 Health Information National Trends Survey, we examined racial/ethnic differences in: (1) breast cancer risk perceptions/worry; (2) the associations between perceived risk/worry and ever having received a mammogram; and (3) perceived risk/worry and having had at least 2 mammograms over a 4-year period (consecutive mammography). Compared to White race/ethnicity, Black race/ethnicity was associated with lower perceived absolute risk and comparative risk for developing cancer. For the sample as a whole, higher perceived risk (both absolute risk and comparative risk) and worry predicted greater odds of mammography use; however, this was not true for Hispanics. In stratified analyses, perceived risk and worry were not associated with mammography use for either Hispanics or Blacks whereas they were for Whites; however, this interaction effect was significant only for Hispanics vs. Whites. Results support the need for formative research to identify determinants of health behavior prior to cancer prevention message planning for diverse audiences in order to accommodate racial/ethnic differences not only in the level of perceived risk, but also the association between risk perception to behavior change in that community.

A population-based study of therapy and survival for patients with head and neck cancer treated in the community.

BACKGROUND: The objective of this study was to examine patterns of care and survival in a population-based sample of patients with head and neck cancer (HNC) who were treated in the community or in hospitals that had residency training programs. METHODS: Data from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program were used to sample 1317 patients aged ≥20 years with invasive squamous HNC who were diagnosed during 2004 and who had vital status available through 2008. RESULTS: Treatment and survival were influenced by tumor site and disease stage. Patients who had stage I/II cancer of the oral cavity generally underwent surgery; patients with stage III oral cavity disease underwent surgery and received radiation; and patients with stage IV oral cavity disease underwent surgery and received chemoradiation. Patients with early stage cancer of the oropharynx either underwent surgery or received radiation and chemotherapy, and patients with late/unstaged oropharyngeal disease primarily received radiation and chemotherapy. Patients with early stage cancer of the larynx mainly received radiation alone, and patients with late stage laryngeal disease generally received chemoradiation. Cisplatin-based regimens were used most frequently. Overall, taxanes were used in 32% of regimens, and cetuximab was used in <3% of regimens. Patients aged ≥50 years, those with a Charlson comorbidity score ≥1, those with stage IV disease, and those with cancer located in the oral cavity or larynx had poorer survival. Although facilities with residency training programs treated more black patients and more patients with late stage disease, when adjusted for other factors, survival rates were similar to those reported in facilities with no such programs. CONCLUSIONS: Therapy generally followed accepted standards for 2004. Findings in particular tumor sites and stages may reflect the variability that still exists for the treatment of HNC. The use of taxanes and cetuximab is expected to increase based on new evidence of benefit. Reducing treatment-related toxicities and long-term functional deficits will be critical and especially important with the increase in human papillomavirus-related cancers. In addition, further attempts to improve survival for older patients are needed.

The state of research on racial/ethnic discrimination in the receipt of health care.

OBJECTIVES: We conducted a review to examine current literature on the effects of interpersonal and institutional racism and discrimination occurring within health care settings on the health care received by racial/ethnic minority patients. METHODS: We searched the PsychNet, PubMed, and Scopus databases for articles on US populations published between January 1, 2008 and November 1, 2011. We used various combinations of the following search terms: discrimination, perceived discrimination, race, ethnicity, racism, institutional racism, stereotype, prejudice or bias, and health or health care. Fifty-eight articles were reviewed. RESULTS: Patient perception of discriminatory treatment and implicit provider biases were the most frequently examined topics in health care settings. Few studies examined the overall prevalence of racial/ethnic discrimination and none examined temporal trends. In general, measures used were insufficient for examining the impact of interpersonal discrimination or institutional racism within health care settings on racial/ethnic disparities in health care. CONCLUSIONS: Better instrumentation, innovative methodology, and strategies are needed for identifying and tracking racial/ethnic discrimination in health care settings.

Racial/ethnic differences in receipt of pelvic lymph node dissection among men with localized/regional prostate cancer.

BACKGROUND: Black and Hispanic men have a lower prostate cancer (PCa) survival rate than white men. This racial/ethnic survival gap has been explained in part by differences in tumor characteristics, stage at diagnosis, and disparities in receipt of definitive treatment. Another potential contributing factor is racial/ethnic differences in the timely and accurate detection of lymph node metastases. The current study was conducted to examine the association between race/ethnicity and the receipt of pelvic lymph node dissection (PLND) among men with localized/regional PCa. METHODS: Logistic regression was used to estimate the adjusted odds of undergoing PLND among men who were diagnosed during 2000 to 2002 with PCa, who underwent radical prostatectomy or PLND without radical prostatectomy, and who were diagnosed in regions covered by the Surveillance, Epidemiology, and End Results database (n = 40,848). RESULTS: Black men were less likely to undergo PLND than white men (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.84-0.98). When the analysis was stratified by PCa grade, black men with well differentiated PCa (OR, 0.48; 95% CI, 0.27-0.84) and poorly differentiated PCa (OR, 0.73; 95% CI, 0.60-0.89) were less likely to undergo PLND than their white counterparts, but racial differences were not observed among men with moderately differentiated PCa (OR, 0.96; 95% CI, 0.88-1.05). CONCLUSIONS: Among men with poorly differentiated PCa, failure to undergo PLND was associated with worse survival. Racial disparities in the receipt of PLND, especially among men with poorly differentiated PCa, may contribute to racial differences in prostate cancer survival.

Racial/ethnic patterns of uptake of colorectal screening, National Health Interview Survey 2000-2008.

BACKGROUND: Lower access and/or utilization of colorectal screening are thought to be major contributors to the higher proportion of cancers among African Americans and Hispanics that are diagnosed at advanced stages of disease and the poorer outcomes observed among Hispanics and African Americans compared with non-Hispanic whites. We examine rates of initiation, utilization of specific screening modalities, adherence tocolorectal screening guidelines, and rate of uptake of colonoscopy among age-eligible African Americans, Hispanics and non-Hispanic whites. METHODS: Data on 46145 African American, Hispanic, and non-Hispanic white survey respondents to the 2000 and 2005 Cancer Control Modules and the 2003 and 2008 Sample Adult Cores of the National Health Interview Surveys are examined in these analyses. RESULTS: There was a modest increase in the initiation of colorectal screening among non-Hispanic whites, only and racial/ethnic disparities colorectal screening utilization persisted. The proportion of respondents for whom colonoscopy was the most complete guideline consistent exam received increased over time, while use of other modalities decreased among all racial/ethnic groups. CONCLUSION: More effort must be made to increase colorectal screening among the U.S. population in general but particularly among racial/ethnic minority populations. With the increased attention on prevention, there is also a need to increase knowledge of the strengths and limitations of specific screening modalities and the need to receive screening exams within recommended time intervals among both patients and providers making screening recommendations.

Race/ethnicity, risk perception, and receipt of prostate-specific antigen testing.

BACKGROUND: Men who do not perceive themselves to be at risk of developing and dying from prostate cancer may be less likely to utilize prostate cancer screening. This, coupled with variation among organizations in recommendations about screening with prostate-specific antigen (PSA), may contribute to confusion for providers and/or patients making prostate cancer screening decisions. METHODS: Data on 1075 African American, Hispanic, and non-Hispanic white male respondents to the 2003 Health Information National Trends Study (HINTS) were analyzed to examine the association among demographic characteristics, perception of the risk of developing prostate cancer, and PSA test utilization among men aged 45 or older. RESULTS: African American men less frequently, while Hispanic men more frequently, perceived their risk of developing prostate cancer to be higher than the average same-age man compared to non-Hispanic white men. Overall, men who perceived their likelihood of getting prostate cancer as very low to moderate (OR, 0.42; 95% CI, 0.24-0.73) or perceived the likelihood compared to the average same age man as less or about as likely (OR, 0.47; 95% CI, 0.27-0.81) were significantly less likely to have received a PSA test in a model adjusted for age, marital status, education, and health insurance coverage. CONCLUSIONS: These findings suggest that all men, but particularly African American and Hispanic men, could benefit from information regarding their specific risk of developing prostate cancer before making a decision about prostate cancer screening.

A biopsychosocial approach to examining tobacco-related health disparities among racially classified social groups.

AIMS: To articulate a broader, multi-causal model that incorporates psychosocial and environmental factors that can differ systematically across racially classified social groups (RCSGs) and impact biological pathways related to the development of tobacco-related diseases. METHODS: This paper is built upon a review of the existing scientific literature on selected biopsychosocial factors (diet/nutrition, obesity, alcoholic intake, psychosocial stress, occupational/environmental exposures and exposure to other diseases and illnesses) and tobacco use in examining the biological contributions to differences in tobacco-related health outcomes among RCSGs. FINDINGS: Recent work has focused on RCSG genetic variations as a possible explanation for differences in tobacco-related health disparities. It is argued in this paper that, given the genetic heterogeneity 'within' RCSGs, it is unlikely that across RCSG genetic variations are likely to be the major source of differences impacting biological pathways in tobacco-related health outcomes. The evidence shows that results, even at the level of within-population genetic variations, have been limited and often inconsistent. A conceptual framework is proposed to account for biological pathways related to the development of tobacco-related diseases. CONCLUSIONS: Determinants of tobacco-related health disparities are not understood clearly. The contribution of biological factors may be important. Current efforts to determine biological differences in tobacco use and related diseases among RCSGs have focused primarily on genetic variations. However, this approach has limitations. An alternative biopsychosocial framework that examines the potential biological mechanisms through which life experiences and behavior might affect tobacco use and health outcomes in these population groups is needed, including those of life-style (e.g. diet/nutrition, obesity, physical exercise, alcohol consumption), psychosocial (e.g. stress and coping), occupational/environmental exposures and the presence of other diseases/illnesses.

Racial/ethnic variation in the anatomic subsite location of in situ and invasive cancers of the colon.

INTRODUCTION: Approximately 145,000 Americans were diagnosed with colorectal cancer and 56,000 died from colorectal cancer in 2006. Although colorectal screening can reduce mortality and incidence, U.S. screening rates are particularly low for racial/ethnic minorities. Racial differences in the subsite location of colon cancers could have implications for colorectal screening. This study examines the anatomic subsite distribution of tumors among African-American, Hispanic, Asian-American/Pacific-Islander and non-Hispanic white (NHW) patients with colon cancer. METHODS: Surveillance and End Results program data for 254,469 primary in situ and invasive colon cancers for patients from 1973-2002 are included in this analysis. Descriptive analyses and logistic regression are used to describe and examine variations in the proportion of colon cancers diagnosed at sites proximal to the sigmoid colon or proximal to the splenic flexure over three successive time periods. RESULTS: The proportion of colon cancers diagnosed at the sigmoid colon was 15.6-21.3% lower, while diagnoses at the descending colon were 40.5.0-45.3.0% higher for African Americans than NHWs over the three time periods. In logistic regression analyses adjusted for gender, age group and year of diagnosis, the odds of a diagnosis of cancer proximal to the sigmoid colon or proximal to the splenic flexure was significantly higher for African Americans but lower for Hispanics and Asian Americans/Pacific Islanders compared to NHWs. DISCUSSION: The higher proportion of cancers among African Americans diagnosed at sites that are generally attempted but not always reached with a sigmoidscope suggest that African Americans may benefit from screening colonoscopy. They also highlight the need for systems that collect data that would allow a direct examination of the role that the differential use of specific colon screening tests and polypectomy play in racial/ethnic variation in colon cancer incidence and in the anatomic subsite distribution of colon cancers.

Measurement of socioeconomic status in health disparities research.

Socioeconomic status (SES) is frequently implicated as a contributor to the disparate health observed among racial/ ethnic minorities, women and elderly populations. Findings from studies that examine the role of SES and health disparities, however, have provided inconsistent results. This is due in part to the: 1) lack of precision and reliability of measures; 2) difficulty with the collection of individual SES data; 3) the dynamic nature of SES over a lifetime; 4) the classification of women, children, retired and unemployed persons; 5) lack of or poor correlation between individual SES measures; and 6) and inaccurate or misleading interpretation of study results. Choosing the best variable or approach for measuring SES is dependent in part on its relevance to the population and outcomes under study. Many of the commonly used compositional and contextual SES measures are limited in terms of their usefulness for examining the effect of SES on outcomes in analyses of data that include population subgroups known to experience health disparities. This article describes SES measures, strengths and limitations of specific approaches and methodological issues related to the analysis and interpretation of studies that examine SES and health disparities.

Employment characteristics and socioeconomic factors associated with disparities in smoking abstinence and former smoking among U.S. workers.

PURPOSE: This study examines the associations among employment and socioeconomic factors and the outcomes, current smoking, cigarette abstinence and former smoking among adult U.S. workers ages 18-64 (n=288,813). METHODS: Multivariate logistic regression was used to examine the associations among the variables using cross-sectional data from the 1998-1999 and 2001-2002 Tobacco Use Supplements to the Current Population Survey. RESULTS: Lower odds of current smoking was observed among part-time workers compared to those working variable hours and multiple job holders compared to persons holding one job. The self-employed, part-time workers and multiple job holders had higher odds of former smoking than comparison groups. Employment factors were not associated with short-term abstinence or 12-month abstinence from smoking, but income, education, marital status, and duration of smoking were associated with 12-month abstinence. CONCLUSIONS: These data suggest that while employment factors are associated with current and former smoking, socioeconomic factors are associated with long-term quitting.

Workplace and home smoking restrictions and racial/ethnic variation in the prevalence and intensity of current cigarette smoking among women by poverty status, TUS-CPS 1998-1999 and 2001-2002.

STUDY OBJECTIVE: Recognition of the health consequences of exposure to environmental tobacco smoke has led government agencies and many employers to establish policies that restrict cigarette smoking in public and workplaces. This cross sectional study examines the association of workplace smoking policies and home smoking restrictions with current smoking among women. DESIGN: Participants were employed US women ages 18-64 who were self respondents to the 1998-1999 or 2000-2001 tobacco use supplement to the current population survey supplements. Cross tabulations and multivariate logistic regression analyses examine the association of selected demographic characteristics, occupation, income, workplace and home smoking policies/restrictions with current smoking, consumption patterns, and quit attempts among women by poverty level for five race/ethnic groups. MAIN RESULTS: The prevalence of either having an official workplace or home smoking policy that completely banned smoking increased with increased distance from the poverty level threshold. A complete ban on home smoking was more frequently reported by African American and Hispanic women although Hispanic women less frequently reported an official workplace smoking policy. In general, policies that permitted smoking in the work area or at home were associated with a higher prevalence of current smoking but this varied by poverty level and race/ethnicity. Home smoking policies that permitted smoking were associated with lower adjusted odds of having a least one quit attempt for nearly all poverty level categories but there was no association between having one quit attempt and workplace policies. CONCLUSION: Home smoking policies were more consistently associated with a lower prevalence of current smoking irrespective of poverty status or race/ethnicity than workplace policies. These findings underscore the importance of examining tobacco control policies in multiple domains (work and home) as well as by race/ethnicity and socioeconomic position.

Racism and health inequity among Americans.

UNLABELLED: Research reports often cite socioeconomic status as an underlying factor in the pervasive disparities in health observed for racial/ethnic minority populations. However, often little information or consideration is given to the social history and prevailing social climate that is responsible for racial/ethnic socioeconomic disparities, namely, the role of racism/racial discrimination. Much of the epidemiologic research on health disparities has focused on the relationship between demographic/clinical characteristics and health outcomes in main-effects multivariate models. This approach, however, does not examine the relationship between covariate levels and the processes that create them. It is important to understand the synergistic nature of these relationships to fully understand the impact they have on health status. PURPOSE: A review of the literature was conducted on the role that discrimination in education, housing, employment, the judicial system and the healthcare system plays in the origination, maintenance and perpetuation of racial/ethnic health disparities to serve as background information for funding Program Announcement, PA-05-006, The Effect of Racial/ Ethnic Discrimination/Bias on Healthcare Delivery (http:// grants.nih.gov/grants/ guide/pa-files/PA-05-006.html). The effect of targeted marketing of harmful products and environmental justice are also discussed as they relate to racial/ethnic disparities in health. CONCLUSION: Racial/ethnic disparities in health are the result of a combination of social factors that influence exposure to risk factors, health behavior and access to and receipt of appropriate care. Addressing these disparities will require a system that promotes equity and mandates accountability both in the social environment and within health delivery systems.

Racial and ethnic disparities in the receipt of cancer treatment.

A disproportionate number of cancer deaths occur among racial/ethnic minorities, particularly African Americans, who have a 33% higher risk of dying of cancer than whites. Although differences in incidence and stage of disease at diagnosis may contribute to racial disparities in mortality, evidence of racial disparities in the receipt of treatment of other chronic diseases raises questions about the possible role of inequities in the receipt of cancer treatment. To evaluate racial/ethnic disparities in the receipt of cancer treatment, we examined the published literature that addressed access/use of specific cancer treatment procedures, trends in patterns of use, or survival studies. We found evidence of racial disparities in receipt of definitive primary therapy, conservative therapy, and adjuvant therapy. These treatment differences could not be completely explained by racial/ethnic variation in clinically relevant factors. In many studies, these treatment differences were associated with an adverse impact on the health outcomes of racial/ethnic minorities, including more frequent recurrence, shorter disease-free survival, and higher mortality. Reducing the influence of nonclinical factors on the receipt of cancer treatment may, therefore, provide an important means of reducing racial/ethnic disparities in health. New data resources and improved study methodology are needed to better identify and quantify the full spectrum of nonclinical factors that contribute to the higher cancer mortality among racial/ethnic minorities and to develop strategies to facilitate receipt of appropriate cancer care for all patients.

Barriers to racial/ethnic minority application and competition for NIH research funding.

BACKGROUND: Despite recognition of the need to increase the pool of racial/ethnic minority investigators, racial/ethnic minority representation among National Institutes of Health (NIH)-funded investigators remains low. Racial/ethnic minority investigators bring unique perspectives and experiences that enhance the potential for understanding factors that underlie racial/ethnic variation in health and health status. Identification of barriers to successful minority competition for NIH funding and suggestions for strategies to overcome them were obtained from a concept mapping project and a meeting of minority investigators and investigators at minority-serving institutions. METHODS: Concept mapping, a mixed-methods planning approach that integrates common data collection processes with multivariate statistical analyses, was used in this exploratory project. The concept mapping approach generated a series of related "concept maps" that were used for data interpretation and meeting discussions. RESULTS: Barriers to minority investigator competition for NIH funding identified by concept mapping participants include: (1) inadequate research infrastructure, training and development; (2) barriers to development as independent researchers; (3) inadequate mentoring; (4) insensitivity, misperceptions and miscommunication about the specific needs of investigators involved in research with minority communities; (5) institutional bias in NIH policies; (6) unfair competitive environment; (7) lack of institutional support; (8) lack of support for research topics/methods relevant to research with minority communities; and (9) social, cultural and environmental barriers. DISCUSSION: Data from both the concept mapping and the meeting discussions suggest the need to use a multilevel approach to increase minority representation among funded NIH investigators. Specifically, the NIH should use strategies that overcome barriers at the home institution, within NIH and at the investigator level.

Racial differences in factors that influence the willingness to participate in medical research studies.

PURPOSE: The relative absence of racial/ethnic minorities among medical research subjects is receiving considerable attention because of recent government mandates for their inclusion in all human subject research. We examined racial differences in the prevalence of sociocultural barriers as a possible explanation for the underrepresentation of African Americans in medical research studies. METHODS: During 1998-1999, a total of 198 residents of the Detroit Primary Metropolitan Statistical Area (PMSA) participated in a survey that examined impediments to participation in medical research studies. Chi square tests and logistic regression analyses were used to examine the association between race, issues related to trust of medical researchers, and the willingness to participate in medical research studies. RESULTS: Study results indicate that African Americans and whites differ in their willingness to participate in medical research. Racial differences in the willingness to participate in a medical research are primarily due to the lower level of trust of medical research among African Americans. African American respondents were also somewhat less willing to participate if they attribute high importance to the race of the doctor when seeking routine medical care, believed that minorities bear most of the risks of medical research, and if their knowledge of the Tuskegee Study resulted in less trust in medical researchers. CONCLUSION: These data reiterate the need for medical researchers to build trusting relationships with minority communities. Researchers can begin by acknowledging the previous medical abuse of minority research participants, discussing their specific plans to assure the protection of study participants, and explaining the need for the participation of racial/ethnic minorities including studies that specifically target or that are likely to result in disproportionate representation of racial/ethnic minorities among study participants.

Trend in the prevalence of overweight and obesity among urban African American hospital employees and public housing residents.

INTRODUCTION: To help understand the impact of socioeconomic status, we examined the current prevalence and age-specific trend in overweight and obesity among two socioeconomically diverse groups of African Americans in the Washington, DC, area. MATERIALS AND METHODS: Data on height and weight were collected between March 1995 and December 1996 as a part of nutrition survey to develop a food frequency questionnaire. Gender-stratified multiple logistic regression analyses were used to examine factors related to the current prevalence of overweight and obesity. RESULTS: Three hundred nine African American public housing residents and 293 African American hospital employees participated in this survey. Overall, hospital workers and public housing residents differed significantly in the distribution of BMI (p = 0.003). Among men, the prevalence of overweight and obesity were 34.9% and 29.4% for hospital workers and 27.0% and 18.2% for public housing residents, respectively. For females these rates were 31.3% and 46.3% for hospital employees and 26.1% and 42.9% for public housing residents, respectively. CONCLUSION: Overweight and obesity were highly prevalent among all age and socioeconomic groups. Future research should focus on a more in-depth study of the relationship between socioeconomic status and the correlates of obesity among African-Americans, particularly women.

Perceived access to health care and its influence on the prevalence of behavioral risks among urban African Americans.

INTRODUCTION: Individuals who have difficulty gaining access to health care may delay seeking and obtaining treatment, underutilize preventive health care services, and may have a high prevalence of chronic disease risks. This report examines participant perception of the level of difficulty encountered when obtaining medical care and its influence on the prevalence of chronic disease behavioral risks among urban African Americans. RESULTS: We found a significantly higher prevalence of current cigarette smoking and alcohol consumption among African Americans who reported that they experienced difficulty in obtaining medical care than among those who did not. Compared to those who experienced no difficulty obtaining care, participants who perceived a high level of difficulty in obtaining care were less likely to have had a physical exam in the past year and to have seen the same doctor when services were obtained. CONCLUSION: The perception of a high level of difficulty obtaining health care may be associated with a higher prevalence of behavioral risks for chronic disease. The limited data suggest a need to more closely examine the perception of health care accessibility and its relationship to health services utilization and the prevalence of chronic disease behavioral risks.
