Racial differences in health: not just black and white, but shades of gray

An Examination of Downward Drift as an Explanation of the Relationship Between Childhood Maltreatment and Residence in Unhealthy Neighborhoods in Adulthood: The Role of Psychiatric Symptoms

This study sought to determine whether downward drift explains relationships among childhood maltreatment, psychiatric disorders, and residence in unhealthy neighborhoods. Using data from a prospective cohort design study, individuals with court substantiated cases of child abuse and/neglect (ages 0-11 during the years 1967-1971) and matched controls were followed up in adulthood. Mental health symptoms and neighborhood disadvantage were measured in young (M_age  = 29) and middle adulthood (M_age  = 40). Physical disorder and social cohesion were also measured in middle adulthood. Childhood maltreatment increased risk for more symptoms of depression, anxiety, and illicit drug use in young adulthood and depression and anxiety in middle adulthood. Childhood maltreatment negatively impacted neighborhood residence in young and middle adulthood, increasing a person's risk of living in neighborhoods with higher levels of physical disorder and economic disadvantage, and lower levels of social cohesion. Neighborhood disadvantage in young adulthood did not increase risk for psychiatric symptoms in middle adulthood. With one exception, neighborhood disadvantage earlier in life, not psychiatric symptoms, helped explain the relationship between childhood maltreatment and living in unhealthy neighborhoods. The negative impact of childhood maltreatment was evident earlier in life and continued into middle adulthood.

Comparisons of Depression, Sexual Function, and Quality of Life Between Women With Gynecological Cancers and Race-Matched Healthy Controls

BACKGROUND

Although higher incidence and mortality of gynecological cancer (GynCa) are documented in black compared with white women, few studies have documented quality of life (QOL) or healthy control comparisons.

OBJECTIVE

This study compared depression, sexual function, and QOL between patients with GynCa and race-matched healthy controls.

METHODS

Patients with GynCa and healthy controls completed the Patient Health Questionnaire-9, Female Sexual Function Index, and Functional Assessment of Cancer Therapy-General measures at baseline; GynCa patients were assessed again at 6 months post-radiation therapy (RT).

RESULTS

Analyses included 84 participants (51% white, 49% black), including 28 GynCa patients and 56 controls with similar marital status. Compared with healthy controls, patients were younger, had a higher body mass index, and had more depression (P = .01); 82% of the patients and 71% of the healthy controls met criteria for sexual dysfunction at baseline (P = .29). Patients pre-RT had greater sexual dysfunction and lower QOL (P = .001) than controls did; patients at 6-month post-RT showed improved sexual function scores compared with pre-RT, with similar results to controls. White GynCa patients reported less sexual desire (P = .02), more pain (P = .05), and lower total Female Sexual Function Index scores (P = .01) than did black GynCa patients. Both black and white GynCa patients reported lower total QOL than their race-matched controls did (P = .07 and P = .002).

CONCLUSIONS

Women with GynCa reported more depression and lower QOL than did healthy controls pre-RT. Among GynCa patients, white women had more sexual dysfunction than black women did.

IMPLICATIONS FOR PRACTICE

The differences in sexual dysfunction between white and black women with GynCa suggest developing guidelines directing routine sexual assessment and rehabilitation in women treated for GynCa.

Trajectories of racial and gender health disparities during later midlife: Connections to personality

OBJECTIVE

We examined race/gender effects on initial levels and trajectories of self-reported physical and mental health, as well as the moderating role of personality. We hypothesized that health disparities would remain stable or decrease over time, and that at-risk personality traits (e.g., neuroticism) would have a more robust negative impact on health for Black participants.

METHOD

Analyses utilized 6 waves of data from a community sample of 1,577 Black and White adults (mean age 60 years), assessed every 6 months for 2.5 years. Using multigroup latent growth curve modeling, we examined initial levels and changes in health among White men, White women, Black men, and Black women.

RESULTS

Black participants reported lower initial physical health than Whites. Women's physical health was stable over time, whereas men's declined. There were no disparities in mental health. Higher agreeableness was associated with higher initial levels of physical health only among Black men and White women. All other personality traits were associated with physical and mental health similarly across race and gender.

CONCLUSIONS

Race and gender influence health trajectories. Most personality- health associations replicated across race and gender, except for agreeableness with physical health. An intersectional framework considering more than one aspect of social identity is crucial for understanding health disparities. Future studies may benefit from including large, diverse samples of participants and further examining the moderating effects of race and gender on personality associations with a variety of health outcomes.

Assessing the Relationship Between a Composite Score of Urban Park Quality and Health

Introduction

Walkable access to parks, sufficient park acreage, and investments in park and recreation resources are 3 indicators of quality city park systems. Few studies, however, have examined the collective effects of these indicators on public health outcomes.

Methods

Combining 3 nationwide public data sets, this study modeled the relationships between a composite score of urban park system quality effects on physical activity and self-reported health while controlling for demographic and lifestyle variables. Data were obtained from the Centers for Disease Control and Prevention’s 500 Cities Project, the Trust for Public Land’s City Park Facts Report, and the US Census Bureau.

Results

Regression analyses indicated that the composite park quality score was significantly related to both physical activity levels and physical health across a sample of 59 cities. Higher scores were associated with fewer physically inactive residents but were not significantly associated with better physical health.

Conclusion

Assessing the collective contribution of park access, park acreage, and investment suggests that improvements to a city’s composite score may correspond with greater physical activity, but more research is needed to establish the long-term relationships between park system quality and physical health.

Examining Life-Course Socioeconomic Position, Contextualized Stress, and Depression among Well-Educated African-American Pregnant Women

PURPOSE

This article explores how childhood and adulthood socioeconomic position (SEP) and socioeconomic mobility, as indicators of life-course experiences, impact the relationship between contextualized stress and depression among well-educated, pregnant African-American women.

METHODS

The Jackson, Hogue, Phillips Contextualized Stress Measure and the Beck Depression Inventory were administered to 101 well-educated, pregnant African-American women during their first and second trimesters. Bivariate associations and regression analysis were conducted to assess life-course SEP, mobility, and contextualized stress as predictors of depression. Based on the demographic data for childhood and adult SES, the SEP and mobility variables were created.

RESULTS

Results from χ2 analysis revealed that high contextual stress was significantly associated with no change in mobility, that is, staying the same. Results from regression models found that contextualized stress was the only predictor for depression. Additionally, life-course SEP and mobility did not moderate the relationship between contextualized stress and depression.

CONCLUSIONS

Our findings illuminated the persistence of racial and gendered stress as risk factors for depression among well-educated, pregnant African-American women, regardless of life-course SEP. We offer an explanation as to why African-American women who possess the material and social resources thought to mediate psychosocial and pregnancy risks remain in jeopardy.

Traumatic stress and cardiopulmonary disease burden among low-income, urban heart failure patients

BACKGROUND

Traumatic events and posttraumatic stress disorder (PTSD) are associated with increased risk for cardiopulmonary disease (CPD) in veterans, men, and primarily White populations. Less is known about trauma, PTSD, and CPD burden among low-income, racial minority residents who are at elevated risk for trauma and PTSD. It was hypothesized that traumatic events and PTSD would be significantly associated with CPD burden among low-income, racial minority residents.

METHODS

We evaluated cross-sectional relationships between traumatic events, PTSD, depression, and CPD burden in 251 low-income, urban, primarily Black adults diagnosed with heart failure. Data were analyzed using bivariate analyses, logistic and linear regression.

RESULTS

Forty-three percent endorsed at least one traumatic event. Twenty-one percent endorsed two or more traumatic events. In logistic regression analyses, traumatic events were associated with increased prevalence of coronary artery disease (adjusted odds=1.33, p<.05), hypertension (adjusted odds=1.28, p<.05), chronic obstructive pulmonary disease (adjusted odds=1.52, p<.01), and cardiac arrest (adjusted odds=1.27, p<.05). PTSD was also related to increased risk for chronic obstructive pulmonary disease (adjusted odds=1.22, p<.05) and was associated with earlier onset of heart failure (β=-.13, p<.05).

LIMITATIONS

The study utilizes cross-sectional, self-report data.

CONCLUSIONS

Findings support the link between traumatic events, PTSD, and CPD burden in low-income, primarily Black patients with heart failure. Depression appears to be less closely linked to CPD burden, despite receiving significant attention in the literature. The accumulation of traumatic events may exacerbate CPD burden among urban, low-income, racial minority residents with heart failure; findings highlight the importance of PTSD screening.

Racial/Ethnic and Socioeconomic Disparities in Mental Health in Arizona

Background

Mental health issues are a rapidly increasing problem in the US. Little is known about mental health and healthcare among Arizona’s Hispanic population.

Methods

We assess differences in mental health service need, mental health diagnoses, and illicit drug use among 7,578 White and Hispanic participants in the 2010 Arizona Health Survey.

Results

Prevalence of mild, moderate, or severe psychological distress was negatively associated with SES among both Whites and Hispanics. Overall, Hispanics were less likely than Whites to have been diagnosed with a mental health condition; however, diagnosis rates were negatively associated with SES among both populations. Hispanics had considerably lower levels of lifetime illicit drug use than their White counterparts. Illicit drug use increased with SES among Hispanics but decreased with SES among Whites. After adjustment for relevant socio-demographic characteristics, multivariable linear regression suggested that Hispanics have significantly lower Kessler scores than Whites. These differences were largely explained by lower Kessler scores among non-English proficient Hispanics relative to English-speaking populations. Moreover, logistic regression suggests that Hispanics, the foreign born, and the non-English language proficient have lower odds of lifetime illicit drug use than Whites, the US born, and the English-language proficient, respectively.

Conclusion

The unique social and political context in Arizona may have important but understudied effects on the physical and mental health of Hispanics. Our findings suggest mental health disparities between Arizona Whites and Hispanics, which should be addressed via culturally- and linguistically tailored mental health care. More observational and intervention research is necessary to better understand the relationship between race/ethnicity, socioeconomic status, healthcare, and mental health in Arizona.

Racial differences in hypertension: implications for high blood pressure management

The racial disparity in hypertension and hypertension-related outcomes has been recognized for decades with African Americans with greater risks than Caucasians. Blood pressure levels have consistently been higher for African Americans with an earlier onset of hypertension. Although awareness and treatment levels of high blood pressure have been similar, racial differences in control rates are evident. The higher blood pressure levels for African Americans are associated with higher rates of stroke, end-stage renal disease and congestive heart failure. The reasons for the racial disparities in elevated blood pressure and hypertension-related outcomes risk remain unclear. However, the implications of the disparities of hypertension for prevention and clinical management are substantial, identifying African American men and women with excel hypertension risk and warranting interventions focused on these differences. In addition, focused research to identify the factors attributed to these disparities in risk burden is an essential need to address the evidence gaps.

Lifetime victimization and physical health outcomes among lesbian and heterosexual women

Background

Lifetime victimization experiences, including child sexual abuse (CSA), child physical abuse (CPA), adult sexual assault (ASA), and adult physical assault (APA), are associated with health problems.

Purpose

To examine relationships between cumulative victimization and physical health among heterosexual and lesbian women and determine whether these relationships differ by sexual identity.

Methods

Large samples of heterosexual (n = 482) and lesbian women (n = 394) were interviewed. Questions included lifetime victimization experiences and physical health problems.

Results

Compared to women who reported no childhood victimization, those who reported experiencing both CSA and CPA were 44% more likely to report health problems and women who experienced all four types of victimization (CSA, CPA, APA, ASA) were nearly 240% as likely to report physical health problems. Interaction analyses revealed the association between victimization and physical health did not differ by sexual identity.

Conclusions

Although lesbians were more likely to report all types of victimization, results suggest that victimization conferred increased physical health risks regardless of sexual identity.

Expressed racial identity and hypertension in a telephone survey sample from Toronto and Vancouver, Canada: do socioeconomic status, perceived discrimination and psychosocial stress explain the relatively high risk of hypertension for Black Canadians?

INTRODUCTION

Canadian research on racial health inequalities that foregrounds socially constructed racial identities and social factors which can explain consequent racial health inequalities is rare. This paper adopts a social typology of salient racial identities in contemporary Canada, empirically documents consequent racial inequalities in hypertension in an original survey dataset from Toronto and Vancouver, Canada, and then attempts to explain the inequalities in hypertension with information on socioeconomic status, perceived experiences with institutionalized and interpersonal discrimination, and psychosocial stress.

METHODS

Telephone interviews were conducted in 2009 with 706 randomly selected adults living in the City of Toronto and 838 randomly selected adults living in the Vancouver Census Metropolitan Area. Bivariate analyses and logistic regression modeling were used to examine relationships between racial identity, hypertension, socio-demographic factors, socioeconomic status, perceived discrimination and psychosocial stress.

RESULTS

The Black Canadians in the sample were the most likely to report major and routine discriminatory experiences and were the least educated and the poorest. Black respondents were significantly more likely than Asian, South Asian and White respondents to report hypertension controlling for age, immigrant status and city of residence. Of the explanatory factors examined in this study, only educational attainment explained some of the relative risk of hypertension for Black respondents. Most of the risk remained unexplained in the models.

CONCLUSIONS

Consistent with previous Canadian research, socioeconomic status explained a small portion of the relatively high risk of hypertension documented for the Black respondents. Perceived experiences of discrimination both major and routine and self-reported psychosocial stress did not explain these racial inequalities in hypertension. Conducting subgroup analyses by gender, discerning between real and perceived experiences of discrimination and considering potentially moderating factors such as coping strategy and internalization of racial stereotypes are important issues to address in future Canadian racial inequalities research of this kind.

Racial Differences in Physical and Mental Health: Socio-economic Status, Stress and Discrimination

This article examines the extent to which racial differences in socio-economic status (SES), social class and acute and chronic indicators of perceived discrimination, as well as general measures of stress can account for black-white differences in self-reported measures of physical and mental health. The observed racial differences in health were markedly reduced when adjusted for education and especially income. However, both perceived discrimination and more traditional measures of stress are related to health and play an incremental role in accounting for differences between the races in health status. These findings underscore the need for research efforts to identify the complex ways in which economic and non-economic forms of discrimination relate to each other and combine with socio-economic position and other risk factors and resources to affect health.

Do empowerment strategies facilitate knowledge and behavioral change? The impact of family health advocacy on health outcomes

This study evaluates the impact of a Family Health Advocacy (FHA) intervention on 46 African American women ages 13 to 35 living in a rural southern community. FHA utilizes empowerment strategies to provide education and social support to reduce risk factors for poor pregnancy outcomes. Use of a paired t test demonstrated a statistically significant difference between pretest and posttest scores in the acquisition of knowledge of safer sex practices, alcohol consumption, early prenatal care, maternal infection, and nutrition. Behavioral change was not realized in the areas of nutrition or behaviors that cause risk of maternal infection. Social workers can influence behavioral change for at-risk populations by addressing microlevel barriers such as education and resources and macrolevel barriers such as advocacy for expanded health and social services.

A symmetrized Theil index measure of health disparities: An example using dental caries in U.S. children and adolescents

While the health status of Americans has generally improved over time, health disparities among groups of the population have been pervasive. Designing a measure that tracks the resulting disparities remains a challenge. In this paper, we propose a new measure of health disparities the Symmetrized Theil Index (STI), and derive its design-based sampling variance in grouped survey data. Because STI is symmetric, it circumvents the drawback of the Theil Index in how groups are weighted: indeed, the latter is mostly influenced by groups with high disease frequencies. Moreover, STI is related to Pearson's chi-square test of independence for binary data, and to the F-test in one-way analysis-of-variance for continuous data. We illustrate our approach using data on dental caries for children and adolescents from the third National Health and Nutrition Examination Surveys (NHANES III; 1988-1994) and NHANES 1999-2004. Tooth decay remains the most common chronic disease in U.S. children and adolescents. Although their oral health has generally improved, we find no change in the prevalence or severity of untreated tooth decay in U.S. children and adolescents between surveys. These findings are consistently observed for both the overall STI and its between-group component across gender, race/ethnicity, country of birth, survey respondent's education, income and poverty-income ratio.

Does racism affect health? Evidence from the United States and the United Kingdom

Blacks have worse overall health than whites in both the United States and the United Kingdom. However, the relative difference in health between the two groups within each cultural context differs between each context. In this article, we attempt to glean insights into these health disparities. We do so by first examining what is currently known about differences in morbidity and mortality for blacks and whites in the United States and the United Kingdom. We then turn to medical examination data by race and country of birth in an attempt to further untangle the complex interplay of socioeconomic status (SES), race, and racism as determinants of health in the United States and the United Kingdom. We find that (1) longer exposure of blacks to the recipient country is a risk for mortality in the United States but not in the United Kingdom; (2) adjustment for SES matters a good deal for mortality in the United States, but less so in the United Kingdom; (3) morbidity indicators do not paint a clear picture of black disadvantage relative to whites in either context; and (4) were one to consider medical examination data alone, differences between the two groups exist only in the United States. Taken together, we conclude that it is possible that the "less racist" United Kingdom provides a healthier environment for blacks than the United States. However, there remain many mysteries that escape simple explanation. Our findings raise more questions than they answer, and the health risks and health status of blacks in the United States are much more complex than previously thought.

School-based health centers: cost-benefit analysis and impact on health care disparities

OBJECTIVES

We evaluated the impact of school-based health centers-which provide essential health care for students by aiming to eliminate many access barriers-on health care access disparities and conducted a cost-benefit analysis.

METHODS

We employed a longitudinal quasi-experimental repeated-measures design. Primary data sources included the Ohio Medicaid claims, enrollment file with race/ethnicity, and survey reports from parents. We used hierarchical linear modeling to control unbalanced data because of student attrition. We assessed quarterly total Medicaid reimbursement costs for 5056 students in the SBHC and non-SBHC groups from 1997 to 2003. We calculated net social benefit to compare the cost of the SBHC programs with the value that SBHCs might save or create.

RESULTS

With SBHCs, the gap of lower health care cost for African Americans was closed. The net social benefits of the SBHC program in 4 school districts were estimated as $1,352,087 over 3 years. We estimated that the SBHCs could have saved Medicaid about $35 per student per year.

CONCLUSIONS

SBHCs are cost beneficial to both the Medicaid system and society, and may close health care disparity gaps.

Black-White health disparities in the United States and Chicago: a 15-year progress analysis

OBJECTIVES

In an effort to examine national and Chicago, Illinois, progress in meeting the Healthy People 2010 goal of eliminating health disparities, we examined whether disparities between non-Hispanic Black and non-Hispanic White persons widened, narrowed, or stayed the same between 1990 and 2005.

METHODS

We examined 15 health status indicators. We determined whether a disparity widened, narrowed, or remained unchanged between 1990 and 2005 by examining the percentage difference in rates between non-Hispanic Black and non-Hispanic White populations at both time points and at each location. We calculated P values to determine whether changes in percentage difference over time were statistically significant.

RESULTS

Disparities between non-Hispanic Black and non-Hispanic White populations widened for 6 of 15 health status indicators examined for the United States (5 significantly), whereas in Chicago the majority of disparities widened (11 of 15, 5 significantly).

CONCLUSIONS

Overall, progress toward meeting the Healthy People 2010 goal of eliminating health disparities in the United States and in Chicago remains bleak. With more than 15 years of time and effort spent at the national and local level to reduce disparities, the impact remains negligible.

African-American women's conceptualizations of health disparities: a community-based participatory research approach

Health disparities among African-American families represent a significant social problem. Nationally, African-American infants have dramatically worse birth outcomes than other racial and ethnic groups. A Community-Based Participatory Research approach was utilized to engage community residents. This study examined participants' definitions of infant mortality, views on the community impact of infant mortality, and strengths and vulnerabilities in the health care service delivery system. Qualitative data were gathered in a rural North Florida community where health education groups are conducted. Eight focus groups were arranged with African-American women (n = 46), ranging in age from 14 to 35, who were pregnant, parenting children under the age of two. Respondents poignantly described personal experiences of loss associated with infant mortality. They indicated awareness of problems related to lack of accessibility and availability of medical and social services. The use of social-ecological theory and implications for policy and social justice are discussed.

Race, ethnicity, and self-reported hypertension: analysis of data from the National Health Interview Survey, 1997-2005

OBJECTIVE

I estimated the association between race and self-reported hypertension among Hispanics and non-Hispanics and determined whether this association was stronger among non-Hispanics.

METHODS

With data from the 1997-2005 National Health Interview Survey, I used logistic regression to estimate the strength of the association between race/ethnicity and self-reported hypertension among US adults.

RESULTS

The overall prevalence of self-reported hypertension was 24.5%, with lower prevalence among Hispanics (16.7%) than among non-Hispanics (25.2%; P < .01). Blacks, regardless of ethnicity, had the highest prevalence. Compared with non-Hispanic Whites, non-Hispanic Blacks had 48% (odds ratio [OR] = 1.48; 95% confidence interval [CI] = 1.41, 1.55) greater odds of reporting hypertension; Hispanic Whites had 23% (OR = 0.81; 95% CI = 0.76, 0.88) lower odds. There was no difference in the strength of the association between race and self-reported hypertension observed among non-Hispanics (OR for Blacks = 1.47) and among Hispanics (OR for Blacks = 1.20; for interaction, P = 0.43).

CONCLUSIONS

The previously reported hypertension advantage of Hispanics holds for Hispanic Whites only. As Hispanics continue their rapid growth in the United States, race may have important implications on their disease burden, because most US health disparities are driven by race and its socially patterned experiences.

Occupational segregation as a determinant of US worker health

BACKGROUND

Racial segregation provides a potential mechanism to link occupations with adverse health outcomes.

METHODS

An African-American segregation index (I(AA)) was calculated for US worker groups from the nationally representative pooled 1986-1994 National Health Interview Survey (n = 451,897). Ranking and logistic regression analyses were utilized to document associations between I(AA) and poor worker health.

RESULTS

There were consistent positive associations between employment in segregated occupations and poor worker health, regardless of covariate adjustment or stratification (e.g., age, gender, income, education, or geographic region). This association between segregation and poor health was stronger for White as compared to African-American workers.

CONCLUSIONS

Occupational segregation negatively affects all workers. Potential mechanisms need to be identified through which occupational segregation may adversely impact worker health.

Genome-wide SNP typing reveals signatures of population history

Single-nucleotide polymorphism (SNP) arrays have become a popular technology for disease-association studies, but they also have potential for studying the genetic differentiation of human populations. Application of the Affymetrix GeneChip Human Mapping 500K Array Set to a population of 102 individuals representing the major ethnic groups in the United States (African, Asian, European, and Hispanic) revealed patterns of gene diversity and genetic distance that reflected population history. We analyzed allelic frequencies at 388,654 autosomal SNP sites that showed some variation in our study population and 10% or fewer missing values. Despite the small size (23-31 individuals) of each subpopulation, there were no fixed differences at any site between any two subpopulations. As expected from the African origin of modern humans, greater gene diversity was seen in Africans than in either Asians or Europeans, and the genetic distance between the Asian and the European populations was significantly lower than that between either of these two populations and Africans. Principal components analysis applied to a correlation matrix among individuals was able to separate completely the major continental groups of humans (Africans, Asians, and Europeans), while Hispanics overlapped all three of these groups. Genes containing two or more markers with extraordinarily high genetic distance between subpopulations were identified as candidate genes for health differences between subpopulations. The results show that, even with modest sample sizes, genome-wide SNP genotyping technologies have great promise for capturing signatures of gene frequency difference between human subpopulations, with applications in areas as diverse as forensics and the study of ethnic health disparities.

Exploring health disparities in integrated communities: overview of the EHDIC study

Progress in understanding the nature of health disparities requires data that are race-comparative while overcoming confounding between race, socioeconomic status, and segregation. The Exploring Health Disparities in Integrated Communities (EHDIC) study is a multisite cohort study that will address these confounders by examining the nature of health disparities within racially integrated communities without racial disparities in socioeconomic status. Data consisted of a structured questionnaire and blood pressure measurements collected from a sample of the adult population (age 18 and older) of two racially integrated contiguous census tracts. This manuscript reports on baseline results from the first EHDIC site, a low-income urban community in southwest Baltimore, Maryland (EHDIC-SWB). In the adjusted models, African Americans had lower rates of smoking and fair or poor self-rated health than whites, but no race differences in obesity, drinking, or physical inactivity. Our findings indicate that accounting for race differences in exposure to social conditions reduces or eliminates some health-related disparities. Moreover, these findings suggest that solutions to the seemingly intractable health disparities problem that target social determinants may be effective, especially those factors that are confounded with racial segregation. Future research in the area of health disparities should seek ways to account for confounding from SES and segregation.

Contextual factors and immigrants' health status: double jeopardy

Poor health among immigrants may be accounted for not only by socio-economic factors affecting individuals but also by the environment in which they live. We investigated the association of contextual factors with disparities in self-rated health between native and immigrant groups. The findings indicated that, compared with native-born Belgians, immigrant groups from Turkey and Morocco were more likely to have poorer self-rated health. When contextual factors and individual socio-economic status were allowed for, all immigrant groups had a health status that was similar to or even better than that of native-born Belgians. Immigrants face a double jeopardy at both the individual and the contextual level.

Self-Rated Health and Race Among Hispanic and Non-Hispanic Adults

OBJECTIVE

To investigate the association between race and self-rated health among Hispanics and non-Hispanics using data from the National Health Interview Survey 2000-2003.

METHODS

This analysis was limited to Hispanic and non-Hispanic whites and blacks > or =18 years of age. The outcome was self-rated health. The main independent variable was race/ethnicity, and potential confounders included sociodemographic characteristics, access to care, health behaviors, and comorbidities.

RESULTS

Non-Hispanic blacks exhibited the highest prevalence of fair/poor self-rated health compared to their white counterparts. In the adjusted analyses, compared to non-Hispanic whites, non-Hispanic blacks (OR: 1.21; 95% CI: 1.16-1.43), Hispanic whites (OR: 1.32; 95% CI: 1.14-1.52) and blacks (OR: 2.19; 95% CI: 1.07-4.49) were more likely to rate their health as fair/poor. There was no difference in self-rated health between Hispanic and non-Hispanic blacks.

DISCUSSION

This study underscores the importance of accounting for the racial heterogeneity among Hispanics when presenting health data. Ignoring race could mask health variations among Hispanics.

The emergency department for routine healthcare: race/ethnicity, socioeconomic status, and perceptual factors

Our objective was to study the role of race/ethnicity and socioeconomic status (SES) in the use of the emergency department (ED) as a source of routine healthcare. Adult patients presenting to an urban ED were surveyed. We assessed demographics, race/ethnicity, SES, and perceptional factors related to choosing the ED for the current visit. Stepwise logistic regression analyses were used to explore whether SES accounted for racial/ethnic trends in ED use. Of 1375 patients, 936 (68%) were enrolled. After controlling for insurance status, income, employment status, and education, neither race nor ethnicity remained a strong predictor of routine ED use. Race/ethnicity-based disparities in routine ED use were due to the confounding effects of SES. Programs to reduce inappropriate ED use must be sensitive to an array of complex socioeconomic issues and may necessitate a substantial paradigm shift in how acute care is provided in low SES communities.

Race/ethnicity, socioeconomic status and the health of pregnant women

We examined how traditional (income, education) and nontraditional (public assistance, material deprivation, subjective social standing) socioeconomic status (SES) indicators were associated with self-rated health, physical functioning, and depression in ethnically diverse pregnant women. Using multiple regression, we estimated the association of race/ethnicity (African American, Latino, Asian/Pacific Islander (PI) and white) and sets of SES measures on each health measure. Education, material deprivation, and subjective social standing were independently associated with all health measures. After adding all SES variables, race/ethnic disparities in depression remained for all minority groups; disparities in self-rated health remained for Asian/Pacific Islanders. Few race/ethnic differences were found in physical functioning. Our results contribute to a small literature on how SES might interact with race/ethnicity in explaining health.

Ethnic difference in the relationship between acute inflammation and serum ferritin in US adult males

This study examined the ethnic difference in the association between increased serum ferritin (SF) (>300 microg/l) and acute inflammation (AI) (C-reactive protein > or = 1.0 mg/dl) between black and white males aged > or = 20 years. Using data from the third National Health and Nutrition Examination Survey (NHANES III), we determined the risk for having elevated SF in black males (n=164) and white males (n=325) with AI present as well as black males (n=1731) and white males (n=2877) with AI absent. Black subjects with AI present were 1.71 times (95% CI 1.18-2.49), and 1.87 times (95% CI 1.46-2.40) more likely to have increased SF than AI absent blacks and AI present whites, respectively. Furthermore, with AI present, every increment of C-reactive protein, white blood cell count, serum albumin, lymphocyte count and platelet count was associated with higher odds of having elevations in SF in blacks than whites. Regardless of AI status, blacks were more likely to have elevations in SF than whites, and the prevalence of elevated SF was significantly higher in blacks than whites. This finding suggested that black males may respond to inflammation with a more aggressive rise in SF compared to white males. Future research is needed to investigate the underlying mechanisms.

Viewpoint: Cultural competence and the African American experience with health care: The case for specific content in cross-cultural education

Achieving cultural competence in the care of a patient who is a member of an ethnic or racial minority is a multifaceted project involving specific cultural knowledge as well as more general skills and attitude adjustments to advance cross-cultural communication in the clinical encounter. Using the important example of the African American patient, the authors examine relevant historical and cultural information as it relates to providing culturally competent health care. The authors identify key influences, including the legacy of slavery, Jim Crow discrimination, the Tuskegee syphilis study, religion's interaction with health care, the use of home remedies, distrust, racial concordance and discordance, and health literacy. The authors propose that the awareness of specific information pertaining to ethnicity and race enhances cross-cultural communication and ways to improve the cultural competence of physicians and other health care providers by providing a historical and social context for illness in another culture. Cultural education, modular in nature, can be geared to the specific populations served by groups of physicians and provider organizations. Educational methods should include both information about relevant social group history as well as some experiential component to emotively communicate particular cultural needs. The authors describe particular techniques that help bridge the cross-cultural clinical communication gaps that are created by patients' mistrust, lack of cultural understanding, differing paradigms for illness, and health illiteracy.

Adolescents entering chemical dependency treatment in private managed care: ethnic differences in treatment initiation and retention

PURPOSE

There has been little research on adolescents of different ethnicities in chemical dependency (CD) treatment, despite a focus on ethnic disparities in health care in recent years. In particular, little is known about ethnic differences in utilization of adolescent CD services.

METHODS

We examined treatment initiation and treatment retention in a sample of African American, Native American, Latino, Asian American, and Caucasian adolescents entering CD treatment in a private, managed care health plan (n = 419). Our conceptual framework included ethnicity as the main factor as well as measures of external pressure and internal motivation/readiness for treatment, family environment, psychiatric co-morbidities, and severity of alcohol and drug problems. Logistic and Poisson regression were used to examine differences.

RESULTS

The study found ethnic differences in treatment initiation and treatment retention. Native American adolescents had lower odds of returning after intake to initiate treatment compared with Caucasians (odds ratio [OR] .35, p = .009), and African American youth spent less time in treatment than Caucasians (RR: .49, p < .001).

CONCLUSIONS

Study findings indicate differences in treatment initiation for Native Americans and in treatment retention for African Americans. Intake and orientation sessions offer an opportunity to intervene with Native American youth. Given their high psychiatric co-morbidity, they may also benefit from the availability of psychiatric services. Even after adjusting for severity, we found shorter treatment retention for African American adolescents and suggest that organizational factors, such as cultural competency, may play an important role.

Maternal resolution of child diagnosis: stability and relations with child attachment across the toddler to preschooler transition

In this longitudinal study, the authors investigated individual differences in how families adapt to a child's congenital disorder. Family impact, maternal grief resolution, and child attachment were assessed among 74 mothers and their toddlers with a neurological disorder or disfigurement. Fifty dyads were reevaluated 16 months later. For children with neurological compared with disfigurement diagnoses, there was a greater likelihood of negative impact on family, unresolved maternal grief, and insecure attachment at Time 1. Children classified as secure were significantly more likely to have mothers classified as resolved regarding their reactions to their children's diagnosis. Maternal grief resolution was significantly stable (77%) over time and mediated the relation between type of diagnosis and child security. With time, negative impact of child condition on the family decreased and percentage of children classified as secure increased, suggesting that on average families improved. Results suggest that helping parents come to terms emotionally and cognitively with their child's condition may be a useful focus for intervention.

The future (history) of socioeconomic measurement and implications for improving health outcomes among African Americans

Socioeconomic status (SES) has powerful and complex impacts on health, and understanding the relationship between SES and health is essential for long-term improvements in the health of populations. In addition, in the United States, the impact of SES on health is inextricably intertwined with racial and ethnicity status and the historical development and maintenance of health disparities. Most of the literature documenting this relationship has focused on individual-level socioeconomic factors. There are sound theoretical reasons and some empirical support to suggest that socioeconomic resources at both individual and neighborhood levels have strong influences on health outcomes such as disease, disability, and mortality. However, these relationships have been inadequately examined to date. In this article, the term "ecological SES" will be used to denote SES at geographic group levels. As the United States attempts to achieve the goals of the Department of Health and Human Services' Healthy People 2010 program, understanding ecological SES and its impacts on health will be crucial. We review the theory, some of the empirical evidence, and likely future for the measurement and use of a broader approach to SES and offer a specific research paradigm for examining these issues. We focus in particular on one racial-ethnic group that experiences health disparity, that is, African Americans. We use our ongoing project investigating physical frailty in urban African Americans to illustrate the importance of a multilevel approach to understanding the impacts of socioeconomic resources on health and the potential implications for efforts to prevent or reverse frailty.

Intervening on the social determinants of cardiovascular disease and diabetes

Heart disease, cerebrovascular diseases, and type 2 diabetes ranked first, third, and sixth, respectively, among the leading causes of death and disability in the United States in 2000. Racial and ethnic communities (i.e., African Americans, Hispanic-Latino Americans, Native Americans and Alaska Natives, and Asian Americans and Pacific Islanders) disproportionately suffer from these chronic conditions. Traditional behavior change strategies have had some positive, but limited effects and will not likely be sufficient to eliminate these health disparities at the population level. In this commentary, the authors argue for greater intervention research directed at the social determinants of cardiovascular disease and diabetes if we are to reverse current trends in chronic disease prevalence in communities of color. The authors also call for new research questions and study designs that will increase our understanding of the social, policy, and historic context in which disparities are created as a necessary first step in developing interventions aimed at social-contextual and psychosocial risk factors. Promising programs supported by the Centers for Disease Control and Prevention's Racial and Ethnic Approaches to Community Health (REACH 2010) program and the Division of Diabetes Translation are highlighted.

The burden of disease associated with being African-American in the United States and the contribution of socio-economic status

The burden of disease associated with being African-American in the US, and the contribution of socio-economic status (SES) to that burden have not been quantified. We derived burden of disease estimates for African-Americans and whites by age group, with and without adjustment for SES (income and education). We used (1) EQ-5D Index scores from the 2000 US Medical Expenditure Panel Survey to derive quality-adjusted life year (QALY) compatible estimates of health-related quality of life (HRQL); (2) 1990-1992 US National Health Interview Survey data linked to National Death Index data through 1995 to derive mortality risks; and (3) 2000 US mortality data from the National Center for Health Statistics to derive current mortality estimates for the US population. We found that relative to whites, African-Americans suffer 67,000 more deaths annually, resulting in 2.2 million years of life lost, and 1.1 million years after SES adjustment. Total QALYs lost (HRQL and mortality) dropped from 2.3 million to 902,000 after SES adjustment. SES differences between African-Americans and whites appear to explain all the HRQL disparity but only half the mortality disparity. Better understanding of the disparate effects of SES may inform interventions to address health disparities adversely affecting African-Americans.

Health disparities and advertising content of women's magazines: a cross-sectional study

Background

Disparities in health status among ethnic groups favor the Caucasian population in the United States on almost all major indicators. Disparities in exposure to health-related mass media messages may be among the environmental factors contributing to the racial and ethnic imbalance in health outcomes. This study evaluated whether variations exist in health-related advertisements and health promotion cues among lay magazines catering to Hispanic, African American and Caucasian women.

Methods

Relative and absolute assessments of all health-related advertising in 12 women's magazines over a three-month period were compared. The four highest circulating, general interest magazines oriented to Black women and to Hispanic women were compared to the four highest-circulating magazines aimed at a mainstream, predominantly White readership. Data were collected and analyzed in 2002 and 2003.

Results

Compared to readers of mainstream magazines, readers of African American and Hispanic magazines were exposed to proportionally fewer health-promoting advertisements and more health-diminishing advertisements. Photographs of African American role models were more often used to advertise products with negative health impact than positive health impact, while the reverse was true of Caucasian role models in the mainstream magazines.

Conclusion

To the extent that individual levels of health education and awareness can be influenced by advertising, variations in the quantity and content of health-related information among magazines read by different ethnic groups may contribute to racial disparities in health behaviors and health status.

Reduction in racial and ethnic disparities after enrollment in the State Children's Health Insurance Program

BACKGROUND

Racial/ethnic disparities are associated with lack of health insurance. Although the State Children's Health Insurance Program (SCHIP) provides health insurance to low-income children, many of whom are members of racial/ethnic minority groups, little is known about whether SCHIP affects racial/ethnic disparities among children who enroll.

OBJECTIVES

The objectives of this study were to (1) describe demographic characteristics and previous health insurance experiences of SCHIP enrollees by race, (2) compare racial/ethnic disparities in medical care access, continuity, and quality before and during SCHIP, and (3) determine whether disparities before or during SCHIP are explained by sociodemographic and health system factors.

METHODS

Pre/post-parent telephone survey was conducted just after SCHIP enrollment and 1 year after enrollment of 2290 children who had an enrollment start date in New York State's SCHIP between November 2000 and March 2001, stratified by race/ethnicity (non-Hispanic white, non-Hispanic black, and Hispanic). The main outcome measures were usual source of care (USC), preventive care use, unmet needs, patterns of USC use, and parent-rated quality of care before versus during SCHIP.

RESULTS

Children were white (25%), black (31%), or Hispanic (44%); 62% were uninsured > or =12 months before SCHIP. Before SCHIP, a greater proportion of white children had a USC compared with black or Hispanic children (95%, 86%, and 81%, respectively). Nearly all children had a USC during SCHIP (98%, 95%, and 98%, respectively). Before SCHIP, black children had significantly greater levels of unmet need relative to white children (38% vs 27%), whereas white and Hispanic children did not differ significantly (27% vs 29%). During SCHIP, racial/ethnic disparities in unmet need were eliminated, with unmet need at 19% for all 3 racial/ethnic groups. Before SCHIP, more white children made all/most visits to their USC relative to black or Hispanic children (61%, 54%, and 34%, respectively); all improved during SCHIP with no remaining disparities (87%, 86%, and 92%, respectively). Parent-rated visit quality improved for all groups, but preexisting racial/ethnic disparities remained during SCHIP, with improved yet relatively lower levels of satisfaction among parents of Hispanic children. Sociodemographic and health system factors did not explain disparities in either period.

CONCLUSIONS

Enrollment in SCHIP was associated with (1) improvement in access, continuity, and quality of care for all racial/ethnic groups and (2) reduction in preexisting racial/ethnic disparities in access, unmet need, and continuity of care. Racial/ethnic disparities in quality of care remained, despite improvements for all racial groups. Sociodemographic and health system factors did not add to the understanding of racial/ethnic disparities. SCHIP improves care for vulnerable children and reduces preexisting racial/ethnic disparities in health care.

Overview of current state of research on pregnancy outcomes in minority populations

Pregnancy outcomes improved significantly over the 20th century in the United States but currently vary widely between women of different ethnic and racial backgrounds. The current health disparities that exist are based, in part, only on differences in socioeconomic status or education. There is wide variability in pregnancy outcomes within specific subgroups of women. Disparities may be due to underlying differences in health before pregnancy, differences in community norms, and individual lifestyle choices and to differences in health care delivery systems. Areas for needed research and promising new models of care are reviewed.

Health-related quality of life in middle-aged African Americans

OBJECTIVES

In this article we explore the measurement properties of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) in 49- to 65-year-old African Americans, compare their health-related quality of life (HRQoL) with that of the nation, and evaluate the association of selected covariates with HRQoL.

METHODS

A probability sample of 998 African Americans in St. Louis received comprehensive in-home assessments. We used an item analysis, exploratory and confirmatory factor analysis, and internal consistency reliability to evaluate the measurement properties of the eight SF-36 scales and their interrelationships. We used a multiple linear regression analysis to characterize the effects of the demographic, socioeconomic status, psychosocial attributes, and biomedical markers.

RESULTS

Assessments averaged 2.5 hr. Each SF-36 scale was unidimensional, all items had robust factor loadings, and all but one scale achieved excellent (alpha > or = .80) internal consistency reliability levels. The overall factor structure of the SF-36 scales was generally consistent with national norms. Substantial variance was explained by the covariates, mostly attributable to socioeconomic status and the biomedical markers.

CONCLUSIONS

The SF-36 is a reliable and valid measure of HRQoL for use with African Americans. In this sample, the HRQoL was below national averages. Future social epidemiologic studies should include grip strength, vision, and hearing assessments, which had substantial and consistent associations with the SF-36 scale scores.

Association of stereotypes about physicians to health care satisfaction, help-seeking behavior, and adherence to treatment

The present research consists of three studies examining the role of patients' stereotypes about health care providers in the health care decision process. Study 1 examined the association of stereotypes to health care satisfaction and help-seeking behavior among a low-income clinic sample; Study 2 examined the relationship of stereotypes to satisfaction and adherence to treatment among low-income individuals living with HIV; and Study 3 examined the association of stereotypes to satisfaction and help-seeking among a sample of homeless individuals. Overall findings indicate that individuals who held more negative stereotypes about physicians sought care less often when sick, were less satisfied with the care that they did obtain, and were less likely to adhere to physician recommendations for treatment. Moreover, African Americans, but not Whites, with more positive stereotypes reported better adherence in Study 2 and were more satisfied with their health care in Study 3. Our findings point to the need to better understand the role of patients' beliefs about health care in predicting health care satisfaction and health behaviors.

Ethnic differences in substance abuse treatment retention, compliance, and outcome from two clinical trials

OBJECTIVE

This study examined the results of two previous studies that evaluated African Americans and whites who were undergoing treatment for cocaine dependence to determine whether the groups differed in pretreatment characteristics, treatment retention, compliance, and cocaine use outcome.

METHODS

Data were taken from two trials (N=111 in each), in which patients were randomly assigned to groups that used different behavioral treatments (cognitive-behavioral treatment and 12-step facilitation) and pharmacotherapies (desipramine and disulfiram).

RESULTS

Few differences between African Americans and whites were found in terms of demographic characteristics, reasons for seeking treatment, or expectations of treatment. In both studies African Americans and whites did not differ significantly with respect to cocaine use outcomes, but African-American participants completed significantly fewer days of treatment than white participants. In study 2, which was not placebo controlled, African Americans who received disulfiram remained in treatment significantly longer than African Americans who did not receive disulfiram. However, in study 1, in which patients took either desipramine or a placebo, no interactions of ethnicity by medication were found. Among patients who expected improvement to take a month or longer in study 1, African Americans remained in treatment for fewer days than whites.

CONCLUSIONS

The behavioral therapies evaluated did not significantly differ in effectiveness for African Americans and whites, suggesting that they are broadly applicable across these ethnic groups. Findings also suggest possible strategies for improving retention of African Americans in treatment. Such strategies might include offering treatment with a medication component and better addressing participants' treatment expectations.

Advancing health disparities research: can we afford to ignore measurement issues?

BACKGROUND

Research on racial and ethnic health disparities in the United States requires that self-report measures, developed primarily in mainstream samples, are appropriate when applied in diverse groups. To compare groups, mean scores must reflect true scores and have minimal bias, assumptions that have not been tested for many self-report measures used in this research.

OBJECTIVE

To identify conceptual and psychometric issues that need to be addressed to assure the quality of self-report measures being used in health disparities research.

METHODS

We present 2 broad conceptual frameworks for health disparities research and describe the main research questions and measurement issues for 4 key concepts hypothesized as potential mechanisms of health disparities: socioeconomic status, discrimination, acculturation, and quality of care. This article is based on a small conference convened by 6 Resource Centers for Minority Aging Research (RCMAR) measurement cores. We integrate written materials prepared for the conference by quantitative and qualitative measurement specialists and cross-cultural researchers, conference discussions, and current literature.

RESULTS

Problems in the quality of the conceptualizations and measures were found for all 4 concepts, and little is known about the extent to which measures of these concepts can be interpreted similarly across diverse groups. Many problems also apply to other concepts relevant to health disparities. We propose an agenda for accomplishing this challenging measurement research.

CONCLUSIONS

The current national commitment to reduce health disparities may be compromised without more research on measurement quality. Integrated, systematic efforts are needed to move this work forward, including collaborative efforts and special initiatives.

Explaining variation in health status across space and time: implications for racial and ethnic disparities in self-rated health

We use the Metropolitan Community Information Center-Metro Survey-a serial cross section of adults residing in the City of Chicago, USA, conducted from 1991 through 1999-in combination with 1990 census data to simultaneously examine the extent to which self-rated health varies across Chicago neighborhoods and across time. Three-level hierarchical logit models are employed to decompose individual, spatial, and temporal variance in self-rated health. Results indicate that variation in self-rated health across neighborhoods is explained, in part, by variation in the level of neighborhood affluence. Neighborhood level poverty, however, is not a significant predictor of self-rated health. Community level affluence, moreover, accounts for a substantial proportion of the residual health deficit experienced by African-Americans when compared with Whites (after controlling for individual level SES). The effects of affluence hold when controlling for spatial autocorrelation and when considered in primarily African-American neighborhoods. Findings also indicate that individuals living in the City of Chicago became significantly healthier over the decade of the 1990s, and that this improvement in health is explained largely by the increasing education and income levels of Chicago residents.

Acute asthma among adults presenting to the emergency department: the role of race/ethnicity and socioeconomic status

OBJECTIVES

To investigate racial/ethnic differences in acute asthma among adults presenting to the emergency department (ED), and to determine whether observed differences are attributable to socioeconomic status (SES).

DESIGN

Prospective cohort studies performed during 1996 to 1998 by the Multicenter Airway Research Collaboration. Using a standardized protocol, researchers provided 24-h coverage for a median duration of 2 weeks per year. Adults with acute asthma were interviewed in the ED and by telephone 2 weeks after hospital discharge.

PARTICIPANTS

Sixty-four North American EDs.

RESULTS

A total of 1,847 patients were enrolled into the study. Black and Hispanic asthma patients had a history of more hospitalizations than did whites (ever-hospitalized patients: black, 66%; Hispanic, 63%; white, 54%; p < 0.001; patients hospitalized in the past year: black, 31%; Hispanic, 33%; white, 25%; p < 0.05) and more frequent ED use (median use in past year: black, three visits; Hispanic, three visits; white, one visit; p < 0.001). The mean initial peak expiratory flow rate (PEFR) was lower in blacks and Hispanics (black, 47%; Hispanic, 47%; white, 52%; p < 0.001). For most factors, ED management did not differ based on race/ethnicity. After accounting for several confounding variables, blacks and Hispanics were twice as likely to be admitted to the hospital. Blacks and Hispanics also were more likely to report continued severe symptoms 2 weeks after hospital discharge (blacks, 24%; Hispanic, 31%; white, 19%; p < 0.01). After adjusting for sociodemographic factors, the race/ethnicity differences in initial PEFR and posthospital discharge symptoms were markedly reduced.

CONCLUSION

Despite significant racial/ethnic differences in chronic asthma severity, initial PEFR at ED presentation, and posthospital discharge outcome, ED management during the index visit was fairly similar for all racial groups. SES appears to account for most of the observed acute asthma differences, although hospital admission rates were higher among black and Hispanic patients after adjustment for confounding factors. Despite asthma treatment advances, race/ethnicity-based deficiencies persist. Health-care providers and policymakers might specifically target the ED as a place to initiate interventions designed to reduce race-based disparities in health.

Impact of race and ethnicity on the outcome of preterm infants below 32 weeks gestation

OBJECTIVES

To determine the impact of race/ethnicity on mortality and morbidity such as intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), bronchopulmonary dysplasia (BPD) and bacteriologically confirmed sepsis, assisted ventilation, surfactant administration, intrauterine growth retardation (IUGR), and patent ductus arteriosus (PDA) among very prematurely delivered infants.

STUDY DESIGN

Retrospective study of a cohort of 1006 preterm neonates with gestational age ranging from 22 to 32 weeks discharged from the Neonatal Intensive Care Unit (NICU) between 1998 and 2001. Subgroup analysis according to gestational age (GA) (22 to 24, 25 to 28, and 29 to 32 weeks) and plurality (singleton and multiple) was performed using the chi(2) test and an analysis of variance.

RESULTS

Of the 1006 infants, 54.3% were white, 21.7% black, 13.7% Hispanic, and 10.3% were classified as Other. Multiple births among white infants were approximately twice that in (42.4%) black infants (22.1%), and was also significantly higher than in the Hispanic (28.3%) and other race/ethnic groups (25.2%). Overall, a higher proportion of black infants were born with a GA <or=28 weeks (n=115, 55.3%) than white (n=201, 37.1%) and Hispanic (n=53, 38.4%), p<0.05. Therefore, black neonates had a lower GA (27.9+/-2.9 weeks) and birth weight (1170+/-463 g) as compared to white (p<0.0002) and Hispanic infants (p<0.0001). There was no significant impact of race/ethnicity on the mean gestational age in any of the gestational age categories. Infant mortality and morbidity in each gestational age category by race/ethnicity were comparable. The multiple birth black infants were seen to have a lower gestational age and birth weight as compared to singleton black as well as to white, Hispanic and other race/ethnic groups. However, this did not influence morbidity and mortality in multiple birth black neonates. The result of this study showed that the level of prematurity and not plurality predominantly influences the rate of infant mortality and morbidity in each race/ethnic category.

CONCLUSIONS

The reduction in gestational age and birth weight in black neonates is not associated with an increased risk of infant mortality and morbidity. In general, the outcomes of black singleton and multiple pregnancies were comparable with those of white, Hispanic and other race/ethnic groups.

Racial/ethnic disparities in overdose mortality trends in New York City, 1990-1998

Racial/ethnic disparities in health and disease have been present in the United States for the past century. Although differences such as individual access to health care and health-related behaviors account for some of these health disparities, it is likely that a combination of individual and contextual-level factors determine the differential rates of disease between racial/ethnic groups. We studied fatal accidental drug overdose in New York City between 1990 and 1998 to describe differences in racial/ethnic patterns over time and to develop hypotheses about factors that might contribute to these differences. During this period, rates of overdose death were consistently higher among blacks and Latinos compared to whites. In addition, cocaine was more common among black decedents, while opiates and alcohol were more common among Latino and white decedents. Differences in situational factors, such as differential likelihood of activating emergency medical response, may in part explain the consistently higher overdose mortality rates observed among minorities. Further study to determine the individual and contextual factors that explain these observed disparities in overdose death may identify effective areas for public health intervention and provide insight into factors underlying racial/ethnic disparities in other health outcomes.
