Classification of race and ethnicity: implications for public health

Population-based comparison of biomarker concentrations for chemicals of concern among Latino-American and non-Hispanic white children

Differences in cultural and economic status may place ethnic subgroups of children at higher risk for exposure, leading to heightened health risks, and health inequities. Although Latino-Americans represent 22% of all children in the United States, few studies have explored within-group differences in their exposure to toxicants. Using socio-demographic and biomarker data from the National Health and Nutrition Examination Survey from 1999 to 2008, we characterized determinants of health and estimated geometric means of environmental contaminant biomarkers (blood concentrations of lead and mercury, serum concentrations of dichlorodiphenyldichloroethylene [p,p'-DDE] and cotinine, and urinary metabolites of organophosphate [OP] pesticides and polycyclic aromatic hydrocarbons [PAHs]) among 4,257 Mexican American (MA), 677 Other Latino-American (OL), and 3,370 Non-Hispanic White (NHW) children. MAs had the lowest levels of health insurance coverage and regular access to health care, and largest household size compared to NHWs and OLs. MAs had higher levels of p,p'-DDE, lead, and cadmium while OLs had higher estimates of mercury relative to other groups. MAs had higher urinary metabolite concentrations of 2-hydroxynaphthalene; otherwise MAs and OLs had lower concentrations of PAHs. NHWs had higher levels of cotinine and dimethylthiophosphate. For other OP metabolites, differences among groups were less clear. Lead and p,p'-DDE exposure differences likely reflect later and less regulatory control of these chemicals in Latin America. Additionally, poor quality housing with lead paint is more common in economically disadvantaged subpopulations. Dietary habits are possible sources of differential cadmium, mercury, and organophosphate exposure. Cotinine exposure differences by income and U.S.- vs. foreign-born may represent increased acculturation. These results, coupled with additional research on exposure sources may contribute to refinement of environmental health promotion programs for the fast-growing Latino-American population.

Protocol of the KTFT-TALK study to reduce racial disparities in kidney transplant evaluation and living donor kidney transplantation

Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). The evaluation process for a kidney transplant is complex, time consuming, and burdensome to the ESKD patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. In December 2012 our transplant center implemented a streamlined, one-day evaluation process, dubbed Kidney Transplant Fast Track (KTFT). This paper describes the protocol of a two-part study to evaluate the effectiveness of KTFT at increasing transplant rates (compared to historical controls) and the TALK intervention (Talking About Live Kidney Donation) at increasing LDKT during KTFT. All participants will receive the KTFT evaluation as part of their usual care. Participants will be randomly assigned to TALK versus no-TALK conditions. Patients will undergo interviews at pre-transplant work-up and transplant evaluation. Transplant status will be tracked via medical records. Our aims are to: (1) test the efficacy and cost effectiveness of the KTFT in reducing time to complete kidney transplant evaluation, and increasing kidney transplant rates relative to standard evaluation practices; (2) test whether TALK increases rates of LDKT during KTFT; and (3) determine whether engaging in a streamlined and coordinated-care evaluation experience within the transplant center reduces negative perceptions of the healthcare system. The results of this two-pronged approach will help pave the way for other transplant centers to implement a fast-track system at their sites, improve quality of care by transplanting a larger number of vulnerable patients, and address stark race/ethnic disparities in rates of LDKT.

Racial/ethnic differences in initiation of and engagement with addictions treatment among patients with alcohol use disorders in the veterans health administration

OBJECTIVE

Specialty addictions treatment can improve outcomes for patients with alcohol use disorders (AUD). Thus, initiation of and engagement with specialty addictions treatment are considered quality care for patients with AUD. Previous studies have demonstrated racial/ethnic differences in alcohol-related care but whether differences exist in initiation of and engagement with specialty addictions treatment among patients with clinically recognized alcohol use disorders is unknown. We investigated racial/ethnic variation in initiation of and engagement with specialty addictions treatment in a national sample of Black, Hispanic, and White patients with clinically recognized alcohol use disorders (AUD) from the US Veterans Health Administration (VA).

METHODS

National VA data were extracted for all Black, Hispanic, and White patients with a diagnosed AUD during fiscal year 2012. Mixed effects regression models estimated the odds of two measures of initiation (an initial visit within 180days of diagnosis; and initiation defined consistent with Healthcare Effectiveness Data and Information Set (HEDIS) as a documented visit ≤14days after index visit or inpatient admission), and three established measures of treatment engagement (≥3 visits within first month after initiation; ≥2 visits in each of the first 3months after initiation; and ≥2 visits within 30days of HEDIS initiation) for Black and Hispanic relative to White patients after adjustment for facility- and patient-level characteristics.

RESULTS

Among 302,406 patients with AUD, 30% (90,879) initiated treatment within 180days of diagnosis (38% Black, 32% Hispanic, and 27% White). Black patients were more likely to initiate treatment than Whites for both measures of initiation [odds ratio (OR) for initiation: 1.4, 95% confidence interval (CI) 1.4-1.4; OR for HEDIS initiation: 1.1, 95% CI: 1.1-1.1]. Hispanic patients were more likely than White patients to initiate treatment within 180days (OR: 1.2, 95% CI 1.2-1.3) but HEDIS initiation did not differ between Hispanic and White patients. Engagement results varied depending on the measure but was more likely for Black patients relative to White for all measures (OR for engagement in first month: 1.1, 95% CI: 1.0-1.1; OR for engagement in first three months: 1.2, 95% CI: 1.1-1.2; OR for HEDIS measure: 1.1, 95% CI: 1.0-1.1), and did not differ between Hispanic and White patients.

CONCLUSIONS

After accounting for facility- and patient-level characteristics, Black and Hispanic patients with AUD were more likely than Whites to initiate specialty addictions treatment, and Black patients were more likely than Whites to engage. Research is needed to understand underlying mechanisms and whether differences in initiation of and engagement with care influence health outcomes.

Reproductive health research of women migrants to Western countries: A systematic review for refining the clinical lens

Influxes of migrant women of childbearing age to Western receiving countries have made their reproductive health a priority in those countries. Yet, providing optimal care to these women may be hampered by an inadequate volume or quality of research to inform practice. We reviewed reports of studies recently published to assess the extent to which current research is able to inform reproductive health care practices for migrant women (i.e., those born in countries other than the receiving country)--in so doing, we sought to offer a view of the landscape from which clinicians may interpret relevant publications. Additionally, we sought to identify topics for which clinicians may choose to advocate for additional research to be performed.

Maternal correlates of body mass index in American Indian/Alaska Native and White adolescents: Differences between mother/son and mother/daughter pairs

INTRODUCTION

Obesity rates for American Indian and Alaska Native (AI/AN) adolescents are among the highest in the US. However, little is known about the influence of maternal correlates on adolescent body mass index (BMI), and the extent to which the size and significance of these correlates vary by adolescent sex and race.

METHODS

We conducted a cross-sectional analysis with a sample of 531 AI/AN and 8896 White mother/adolescent pairs from Wave 1 of the National Longitudinal Study of Adolescent to Adult Health. We used generalized estimating equations to measure the association of maternal educational attainment, marital status, employment status, obesity status, and adolescent BMI of AI/AN and White adolescents, while controlling for adolescents' demographic and behavioral covariates. We sought to determine whether the size and statistical significance of maternal correlates differed by race, and between mother/son and mother/daughter pairs.

RESULTS

The strength and statistical significance of maternal correlates varied between mother/son and mother/daughter pairs in both races. However, we did not find effect modification by race. Maternal obesity showed the strongest effect on adolescent BMI in all mother/adolescent pairs.

CONCLUSION

Our findings suggest that maternal factors are critical in the transmission of obesogenic behaviors from one generation to the next, and their effects vary between mother/son and mother/daughter pairs, and are similar for AI/ANs and Whites. We encourage future work aimed at preventing adolescent obesity to investigate causal pathways between maternal correlates and adolescent BMI.

Disparities in Temporal and Geographic Patterns of Declining Heart Disease Mortality by Race and Sex in the United States, 1973-2010

BACKGROUND

Examining small-area differences in the strength of declining heart disease mortality by race and sex provides important context for current racial and geographic disparities and identifies localities that could benefit from targeted interventions. We identified and described temporal trends in declining county-level heart disease mortality by race, sex, and geography between 1973 and 2010.

METHODS AND RESULTS

Using a Bayesian hierarchical model, we estimated age-adjusted mortality with diseases of the heart listed as the underlying cause for 3099 counties. County-level percentage declines were calculated by race and sex for 3 time periods (1973-1985, 1986-1997, 1998-2010). Strong declines were statistically faster or no different than the total national decline in that time period. We observed county-level race-sex disparities in heart disease mortality trends. Continual (from 1973 to 2010) strong declines occurred in 73.2%, 44.6%, 15.5%, and 17.3% of counties for white men, white women, black men, and black women, respectively. Delayed (1998-2010) strong declines occurred in 15.4%, 42.0%, 75.5%, and 76.6% of counties for white men, white women, black men, and black women, respectively. Counties with the weakest patterns of decline were concentrated in the South.

CONCLUSIONS

Since 1973, heart disease mortality has declined substantially for these race-sex groups. Patterns of decline differed by race and geography, reflecting potential disparities in national and local drivers of these declines. Better understanding of racial and geographic disparities in the diffusion of heart disease prevention and treatment may allow us to find clues to progress toward racial and geographic equity in heart disease mortality.

Assessing race and ethnicity data quality across cancer registries and EMRs in two hospitals

BACKGROUND

Measurement of patient race/ethnicity in electronic health records is mandated and important for tracking health disparities.

OBJECTIVE

Characterize the quality of race/ethnicity data collection efforts.

METHODS

For all cancer patients diagnosed (2007-2010) at two hospitals, we extracted demographic data from five sources: 1) a university hospital cancer registry, 2) a university electronic medical record (EMR), 3) a community hospital cancer registry, 4) a community EMR, and 5) a joint clinical research registry. The patients whose data we examined (N = 17 834) contributed 41 025 entries (range: 2-5 per patient across sources), and the source comparisons generated 1-10 unique pairs per patient. We used generalized estimating equations, chi-squares tests, and kappas estimates to assess data availability and agreement.

RESULTS

Compared to sex and insurance status, race/ethnicity information was significantly less likely to be available (χ(2 )> 8043, P < .001), with variation across sources (χ(2 )> 10 589, P < .001). The university EMR had a high prevalence of "Unknown" values. Aggregate kappa estimates across the sources was 0.45 (95% confidence interval, 0.45-0.45; N = 31 276 unique pairs), but improved in sensitivity analyses that excluded the university EMR source (κ = 0.89). Race/ethnicity data were in complete agreement for only 6988 patients (39.2%). Pairs with a "Black" data value in one of the sources had the highest agreement (95.3%), whereas pairs with an "Other" value exhibited the lowest agreement across sources (11.1%).

DISCUSSION

Our findings suggest that high-quality race/ethnicity data are attainable. Many of the "errors" in race/ethnicity data are caused by missing or "Unknown" data values.

CONCLUSIONS

To facilitate transparent reporting of healthcare delivery outcomes by race/ethnicity, healthcare systems need to monitor and enforce race/ethnicity data collection standards.

Prevalence of occupational exposure to carcinogens among workers of Arabic, Chinese and Vietnamese ancestry in Australia

BACKGROUND

Although job-related diseases result in more deaths per year than job-related injuries, most research concerning ethnic minority workers has concerned accidents and injuries rather than disease-causing exposures such as carcinogens.

METHODS

We conducted a telephone-based cross-sectional survey to estimate the prevalence of occupational exposure to carcinogens among a sample of ethnic minority workers in Australia, and compared their exposure prevalence to that of a sample of the general Australian-born working population ('Australian workers').

RESULTS

One-third of the ethnic minority workers were exposed to at least one carcinogen at work. The likelihood of exposure to carcinogens was not significantly different from that of Australian workers, although the likelihood of exposure to individual carcinogens varied by ethnicity.

CONCLUSION

Knowing the prevalence of exposure to carcinogens in the workplace in different ethnic groups will allow better targeted and informed occupational health and safety measures to be implemented where necessary.

Race, Ethnicity and Ancestry in Unrelated Transplant Matching for the National Marrow Donor Program: A Comparison of Multiple Forms of Self-Identification with Genetics

We conducted a nationwide study comparing self-identification to genetic ancestry classifications in a large cohort (n = 1752) from the National Marrow Donor Program. We sought to determine how various measures of self-identification intersect with genetic ancestry, with the aim of improving matching algorithms for unrelated bone marrow transplant. Multiple dimensions of self-identification, including race/ethnicity and geographic ancestry were compared to classifications based on ancestry informative markers (AIMs), and the human leukocyte antigen (HLA) genes, which are required for transplant matching. Nearly 20% of responses were inconsistent between reporting race/ethnicity versus geographic ancestry. Despite strong concordance between AIMs and HLA, no measure of self-identification shows complete correspondence with genetic ancestry. In certain cases geographic ancestry reporting matches genetic ancestry not reflected in race/ethnicity identification, but in other cases geographic ancestries show little correspondence to genetic measures, with important differences by gender. However, when respondents assign ancestry to grandparents, we observe sub-groups of individuals with well- defined genetic ancestries, including important differences in HLA frequencies, with implications for transplant matching. While we advocate for tailored questioning to improve accuracy of ancestry ascertainment, collection of donor grandparents' information will improve the chances of finding matches for many patients, particularly for mixed-ancestry individuals.

RACE AS LIVED EXPERIENCE: The Impact of Multi-Dimensional Measures of Race/Ethnicity on the Self-Reported Health Status of Latinos

A growing body of social science research has sought to conceptualize race as a multidimensional concept in which context, societal relations, and institutional dynamics are key components. Utilizing a specially designed survey, we develop and use multiple measures of race (skin color, ascribed race, and discrimination experiences) to capture race as "lived experience" and assess their impact on Latinos' self-rated health status. We model these measures of race as a lived experience to test the explanatory power of race, both independently and as an integrated scale with categorical regression, scaling, and dimensional analyses. Our analyses show that our multiple measures of race have significant and negative effects on Latinos' self-reported health. Skin color is a dominant factor that impacts self-reported health both directly and indirectly. We then advocate for the utilization of multiple measures of race, adding to those used in our analysis, and their application to other health and social outcomes. Our analysis provides important contributions across a wide range of health, illness, social, and political outcomes for communities of color.

Differential environmental exposure among non-Indigenous Canadians as a function of sex/gender and race/ethnicity variables: a scoping review

OBJECTIVES

To determine the extent, range and types of studies of differential environmental chemical exposures among non-Indigenous Canadians as a function of sex/gender and race/ethnicity.

METHODS

Computerized database searches were performed from November to December 2013 using Medline, Embase, CAB Abstracts, Proquest and Scopus to identify relevant studies of environmental exposures among non-Indigenous adults aged ≥18 years in Canada published between 1993 and 2013. Articles were identified for full-text review based on a screening of titles and abstracts and were excluded during this initial review if they focused on environmental exposures in the following populations: 1) Indigenous populations, 2) individuals &lt;15 years of age, 3) pregnant women and associated negative birth outcomes, or 4) non-Canadian populations. Articles were also excluded if the primary focus was on exposures to environmental tobacco smoke, non-chemical occupational hazards, infectious diseases, noise and/or radiation. A full-text review of 78 identified articles systematically assessed how sex/gender and race/ethnicity were considered.

SYNTHESIS

Although 59% of studies stratified results by sex, less than half of these offered any explanation of differential exposures. Eighteen of the 78 studies (23%) used terms related to race/ethnicity in their participant descriptions. Of the studies that conducted subgroup analyses of exposure results by race/ethnicity (n=15), a total of 8 also included subgroup analysis by sex. Overall, 3 of the 78 (3%) articles reviewed analyzed environmental exposures as a function of sex/gender and race/ethnicity.

CONCLUSION

The role of sex/gender and race/ethnicity in influencing environmental exposure levels among non-Indigenous Canadians has not been adequately addressed to date.

Confidence in the fairness of local public health systems’ response to disasters: the US Veterans’ perspective

OBJECTIVE

The effectiveness of local public health systems in emergency management depends on trust from the entire community. However, the failure of some government agencies to respond effectively to several major disasters has had a disproportionate impact on certain groups-racial/ethnic minorities, in particular-that are well-represented in the veteran population. Many veterans belong to multiple vulnerable populations at greater risk of harm during disasters. This study examines confidence that local public health systems will respond fairly to disasters in a diverse sample of US veterans.

METHODS

This study is an analysis of cross-sectional data on 5955 veterans in the 2009 California Health Interview Survey. Respondents were asked about their confidence that public health systems would respond fairly to their needs in the event of a disaster, regardless of their race/ethnicity or other personal characteristics. Multivariable regression analysis was used to identify variables on respondent characteristics that were independently associated with confidence. The hypothesis was that there would be less confidence in county public health systems among respondents who were racial/ethnic minorities, had less than a college degree, and were of low-income backgrounds.

RESULTS

Approximately 79% of veterans were confident that public health systems would respond fairly. The hypothesis was unsupported, with no differences in confidence by race/ethnicity, education, or income. Also, no differences were noted between men and women or between veterans with and without disabilities. However, confidence was associated with continent of birth, age, homeownership, and marital status.

CONCLUSION

If confidence affects veterans’ willingness to accept disaster preparedness communications or to give proper consideration to recommended emergency countermeasures, then local health departments that issue such information to veterans are not likely to encounter barriers by race/ethnicity, income, education, disability status, or gender.

Moving to patient reported collection of race and ethnicity data: implementation and impact in ten hospitals

PURPOSE

The purpose of this paper is to examine the feasibility of collecting standardized, patient reported race and ethnicity (RE) data in hospitals, and to assess the impact on data quality and utility.

DESIGN/METHODOLOGY/APPROACH

Part of a larger evaluation that included a comprehensive assessment. Sites documented RE data collection procedures before and after program implementation. Primary data collected through qualitative interviewing with key respondents in ten hospitals to assess implementation. Nine hospitals provided RE data on the same patients before and after implementation new data collection procedures were implemented to assess impact.

FINDINGS

Implementation went smoothly in nine of ten hospitals and had substantial effects on the hospital staff awareness on the potential for disparities within their hospitals. New procedures had minimal impact on characterization of readmitted patients.

PRACTICAL IMPLICATIONS

This study demonstrated that it is feasible for staff in a diverse group of hospitals to implement systematic, internally standardized methods to collect self-reported RE data from patients.

ORIGINALITY/VALUE

Although this study found little impact patients' demographic characterizations, other benefits included greater awareness of and attention to disparities, uncovering small pockets of minorities, and dramatically increased RE data use in quality improvement efforts.

Associations of census-tract poverty with subsite-specific colorectal cancer incidence rates and stage of disease at diagnosis in the United States

Background. It remains unclear whether neighborhood poverty contributes to differences in subsite-specific colorectal cancer (CRC) incidence. We examined associations between census-tract poverty and CRC incidence and stage by anatomic subsite and race/ethnicity. Methods. CRC cases diagnosed between 2005 and 2009 from 15 states and Los Angeles County (N = 278,097) were assigned to 1 of 4 groups based on census-tract poverty. Age-adjusted and stage-specific CRC incidence rates (IRs) and incidence rate ratios (IRRs) were calculated. Analyses were stratified by subsite (proximal, distal, and rectum), sex, race/ethnicity, and poverty. Results. Compared to the lowest poverty areas, CRC IRs were significantly higher in the most impoverished areas for men (IRR = 1.14 95% CI 1.12-1.17) and women (IRR = 1.06 95% CI 1.05-1.08). Rate differences between high and low poverty were strongest for distal colon (male IRR = 1.24 95% CI 1.20-1.28; female IRR = 1.14 95% CI 1.10-1.18) and weakest for proximal colon. These rate differences were significant for non-Hispanic whites and blacks and for Asian/Pacific Islander men. Inverse associations between poverty and IRs of all CRC and proximal colon were found for Hispanics. Late-to-early stage CRC IRRs increased monotonically with increasing poverty for all race/ethnicity groups. Conclusion. There are differences in subsite-specific CRC incidence by poverty, but associations were moderated by race/ethnicity.

Persisting problems related to race and ethnicity in public health and epidemiology research

A recent and comprehensive review of the use of race and ethnicity in research that address health disparities in epidemiology and public health is provided. First it is described the theoretical basis upon which race and ethnicity differ drawing from previous work in anthropology, social science and public health. Second, it is presented a review of 280 articles published in high impacts factor journals in regards to public health and epidemiology from 2009-2011. An analytical grid enabled the examination of conceptual, theoretical and methodological questions related to the use of both concepts. The majority of articles reviewed were grounded in a theoretical framework and provided interpretations from various models. However, key problems identified include a) a failure from researchers to differentiate between the concepts of race and ethnicity; b) an inappropriate use of racial categories to ascribe ethnicity; c) a lack of transparency in the methods used to assess both concepts; and d) failure to address limits associated with the construction of racial or ethnic taxonomies and their use. In conclusion, future studies examining health disparities should clearly establish the distinction between race and ethnicity, develop theoretically driven research and address specific questions about the relationships between race, ethnicity and health. One argue that one way to think about ethnicity, race and health is to dichotomize research into two sets of questions about the relationship between human diversity and health.

Sampling in Developmental Science: Situations, Shortcomings, Solutions, and Standards

Sampling is a key feature of every study in developmental science. Although sampling has far-reaching implications, too little attention is paid to sampling. Here, we describe, discuss, and evaluate four prominent sampling strategies in developmental science: population-based probability sampling, convenience sampling, quota sampling, and homogeneous sampling. We then judge these sampling strategies by five criteria: whether they yield representative and generalizable estimates of a study's target population, whether they yield representative and generalizable estimates of subsamples within a study's target population, the recruitment efforts and costs they entail, whether they yield sufficient power to detect subsample differences, and whether they introduce "noise" related to variation in subsamples and whether that "noise" can be accounted for statistically. We use sample composition of gender, ethnicity, and socioeconomic status to illustrate and assess the four sampling strategies. Finally, we tally the use of the four sampling strategies in five prominent developmental science journals and make recommendations about best practices for sample selection and reporting.

Does the Cultural Formulation Interview for the fifth revision of the diagnostic and statistical manual of mental disorders (DSM-5) affect medical communication? A qualitative exploratory study from the New York site

OBJECTIVES

Cross-cultural mental health researchers often analyze patient explanatory models of illness to optimize service provision. The Cultural Formulation Interview (CFI) is a cross-cultural assessment tool released in May 2013 with DSM-5 to revise shortcomings from the DSM-IV Outline for Cultural Formulation (OCF). The CFI field trial took place in 6 countries, 14 sites, and with 321 patients to explore its feasibility, acceptability, and clinical utility with patients and clinicians. We sought to analyze if and how CFI feasibility, acceptability, and clinical utility were related to patient-clinician communication.

DESIGN

We report data from the New York site which enrolled 7 clinicians and 32 patients in 32 patient-clinician dyads. We undertook a data analysis independent of the parent field trial by conducting content analyses of debriefing interviews with all participants (n = 64) based on codebooks derived from frameworks for medical communication and implementation outcomes. Three coders created codebooks, coded independently, established inter-rater coding reliability, and analyzed if the CFI affects medical communication with respect to feasibility, acceptability, and clinical utility.

RESULTS

Despite racial, ethnical, cultural, and professional differences within our group of patients and clinicians, we found that promoting satisfaction through the interview, eliciting data, eliciting the patient's perspective, and perceiving data at multiple levels were common codes that explained how the CFI affected medical communication. We also found that all but two codes fell under the implementation outcome of clinical utility, two fell under acceptability, and none fell under feasibility.

CONCLUSION

Our study offers new directions for research on how a cultural interview affects patient-clinician communication. Future research can analyze how the CFI and other cultural interviews impact medical communication in clinical settings with subsequent effects on outcomes such as medication adherence, appointment retention, and health condition.

The unique impact of abolition of Jim Crow laws on reducing inequities in infant death rates and implications for choice of comparison groups in analyzing societal determinants of health

OBJECTIVES

We explored associations between the abolition of Jim Crow laws (i.e., state laws legalizing racial discrimination overturned by the 1964 US Civil Rights Act) and birth cohort trends in infant death rates.

METHODS

We analyzed 1959 to 2006 US Black and White infant death rates within and across sets of states (polities) with and without Jim Crow laws.

RESULTS

Between 1965 and 1969, a unique convergence of Black infant death rates occurred across polities; in 1960 to 1964, the Black infant death rate was 1.19 times higher (95% confidence interval [CI] = 1.18, 1.20) in the Jim Crow polity than in the non-Jim Crow polity, whereas in 1970 to 1974 the rate ratio shrank to and remained at approximately 1 (with the 95% CI including 1) until 2000, when it rose to 1.10 (95% CI = 1.08, 1.12). No such convergence occurred for Black-White differences in infant death rates or for White infants.

CONCLUSIONS

Our results suggest that abolition of Jim Crow laws affected US Black infant death rates and that valid analysis of societal determinants of health requires appropriate comparison groups.

Classification of Canadian immigrants into visible minority groups using country of birth and mother tongue

BACKGROUND

The Permanent Resident Database of Citizenship and Immigration Canada (CIC) contains sociodemographic information on immigrants but lacks ethnic group classifications. To enhance its usability for ethnicityrelated research, we categorized immigrants in the CIC database into one of Canada's official visible minority groups or a white category using their country of birth and mother tongue.

METHODS

Using public data sources, we classified each of 267 country names and 245 mother tongues in the CIC data into 1 of 10 visible minority groups (South Asian, Chinese, black, Latin American, Filipino, West Asian, Arab, Southeast Asian, Korean, and Japanese) or a white group. We then used country of birth alone (method A) or country of birth plus mother tongue (method B) to classify 2.5 million people in the CIC database who immigrated to Ontario between 1985 and 2010 and who had a valid encrypted health card number. We validated the ethnic categorizations using linked selfreported ethnicity data for 6499 people who responded to the Canadian Community Health Survey (CCHS).

RESULTS

Among immigrants listed in the CIC database, the 4 most frequent visible minority groups as classified by method B were South Asian (n = 582 812), Chinese (n = 400 771), black (n = 254 189), and Latin American (n = 179 118). Methods A and B agreed in 94% of the categorizations (kappa coefficient 0.94, 95% confidence interval [CI] 0.93-0.94). Both methods A and B agreed with self-reported CCHS ethnicity in 86% of all categorizations (for both comparisons, kappa coefficient 0.83, 95% CI 0.82-0.84). Both methods A and B had high sensitivity and specificity for most visible minority groups when validated using self-reported ethnicity from the CCHS (e.g., with method B, sensitivity and specificity were, respectively, 0.85 and 0.97 for South Asians, 0.93 and 0.99 for Chinese, and 0.90 and 0.97 for blacks).

INTERPRETATION

The use of country of birth and mother tongue is a validated and practical method for classifying immigrants to Canada into ethnic categories.

Association of race and ethnicity with management of abdominal pain in the emergency department

OBJECTIVE

To determine if race/ethnicity-based differences exist in the management of pediatric abdominal pain in emergency departments (EDs).

METHODS

Secondary analysis of data from the 2006-2009 National Hospital Ambulatory Medical Care Survey regarding 2298 visits by patients ≤ 21 years old who presented to EDs with abdominal pain. Main outcomes were documentation of pain score and receipt of any analgesics, analgesics for severe pain (defined as ≥ 7 on a 10-point scale), and narcotic analgesics. Secondary outcomes included diagnostic tests obtained, length of stay (LOS), 72-hour return visits, and admission.

RESULTS

Of patient visits, 70.1% were female, 52.6% were from non-Hispanic white, 23.5% were from non-Hispanic black, 20.6% were from Hispanic, and 3.3% were from "other" racial/ethnic groups; patients' mean age was 14.5 years. Multivariate logistic regression models adjusting for confounders revealed that non-Hispanic black patients were less likely to receive any analgesic (odds ratio [OR]: 0.61; 95% confidence interval [CI]: 0.43-0.87) or a narcotic analgesic (OR: 0.38; 95% CI: 0.18-0.81) than non-Hispanic white patients (referent group). This finding was also true for non-Hispanic black and "other" race/ethnicity patients with severe pain (ORs [95% CI]: 0.43 [0.22-0.87] and 0.02 [0.00-0.19], respectively). Non-Hispanic black and Hispanic patients were more likely to have a prolonged LOS than non-Hispanic white patients (ORs [95% CI]: 1.68 [1.13-2.51] and 1.64 [1.09-2.47], respectively). No significant race/ethnicity-based disparities were identified in documentation of pain score, use of diagnostic procedures, 72-hour return visits, or hospital admissions.

CONCLUSIONS

Race/ethnicity-based disparities exist in ED analgesic use and LOS for pediatric abdominal pain. Recognizing these disparities may help investigators eliminate inequalities in care.

Experimental U.S. Census Bureau Race and Hispanic Origin Survey Questions

People of Hispanic origin, including monolingual Spanish speakers, have experienced difficulty identifying with a race category on U.S. demographic surveys. As part of a larger research effort by the U.S. Census Bureau to improve race and Hispanic origin questions for the 2020 Census, we tested experimental versions of race and Hispanic origin questions in Spanish. About half of the versions asked about race and Hispanic origin in separate questions, while the rest asked about these constructs in a combined question format. Cognitive interviews with 33 monolingual Spanish-speaking participants indicated that (a) most participants affirmatively claimed Hispanic origin on the separate and combined formats, but had difficulty selecting or declined to select a race category on the separate question formats and (b) most participants perceived few differences between Hispanic origin and race. In comparison with the separate race and Hispanic origin questions, the combined question facilitated more satisfactory self-identifications.

Validity of infant race/ethnicity from birth certificates in the context of U.S. demographic change

OBJECTIVE

To compare infant race/ethnicity based on birth certificates with parent report of infant race/ethnicity in a survey.

DATA SOURCES

The 2007 Oklahoma birth certificates and SEED for Oklahoma Kids baseline survey.

STUDY DESIGN

Using sensitivity scores and positive predictive values, we examined consistency of infant race/ethnicity across two data sources (N = 2,663).

DATA COLLECTION/EXTRACTION METHODS

We compared conventional measures of infant race/ethnicity from birth certificate and survey data. We also tested alternative measures that allow biracial classification, determined from parental information on the infant's birth certificate or parental survey report.

PRINCIPAL FINDINGS

Sensitivity of conventional measures is highest for whites and African Americans and lowest for Hispanics; positive predictive value is highest for Hispanics and African Americans and lowest for American Indians. Alternative measures improve values among whites but yield mostly low values among minority and biracial groups.

CONCLUSIONS

Health disparities research should consider the source and validity of infant race/ethnicity data when creating sampling frames or designing studies that target infants by race/ethnicity. The common practice of assigning the maternal race/ethnicity as infant race/ethnicity should continue to be challenged.

Accuracy of routinely recorded ethnic group information compared with self-reported ethnicity: evidence from the English Cancer Patient Experience survey

OBJECTIVE

To describe the accuracy of ethnicity coding in contemporary National Health Service (NHS) hospital records compared with the 'gold standard' of self-reported ethnicity.

DESIGN

Secondary analysis of data from a cross-sectional survey (2011).

SETTING

All NHS hospitals in England providing cancer treatment.

PARTICIPANTS

58 721 patients with cancer for whom ethnicity information (Office for National Statistics 2001 16-group classification) was available from self-reports (considered to represent the 'gold standard') and their hospital record.

METHODS

We calculated the sensitivity and positive predictive value (PPV) of hospital record ethnicity. Further, we used a logistic regression model to explore independent predictors of discordance between recorded and self-reported ethnicity.

RESULTS

Overall, 4.9% (4.7-5.1%) of people had their self-reported ethnic group incorrectly recorded in their hospital records. Recorded White British ethnicity had high sensitivity (97.8% (97.7-98.0%)) and PPV (98.1% (98.0-98.2%)) for self-reported White British ethnicity. Recorded ethnicity information for the 15 other ethnic groups was substantially less accurate with 41.2% (39.7-42.7%) incorrect. Recorded 'Mixed' ethnicity had low sensitivity (12-31%) and PPVs (12-42%). Recorded 'Indian', 'Chinese', 'Black-Caribbean' and 'Black African' ethnic groups had intermediate levels of sensitivity (65-80%) and PPV (80-89%, respectively). In multivariable analysis, belonging to an ethnic minority group was the only independent predictor of discordant ethnicity information. There was strong evidence that the degree of discordance of ethnicity information varied substantially between different hospitals (p<0.0001).

DISCUSSION

Current levels of accuracy of ethnicity information in NHS hospital records support valid profiling of White/non-White ethnic differences. However, profiling of ethnic differences in process or outcome measures for specific minority groups may contain a substantial and variable degree of misclassification error. These considerations should be taken into account when interpreting ethnic variation audits based on routine data and inform initiatives aimed at improving the accuracy of ethnicity information in hospital records.

Initiation and persistence with warfarin therapy in atrial fibrillation according to ethnicity

The aim of this study was to investigate initiation of and persistence with warfarin treatment in patients with atrial fibrillation (AF) according to ethnicity. Patients hospitalized with first-time AF from 1997 to 2009, prescription claims of warfarin and country of birth were identified by individual-level linkage of nationwide administrative agencies. Cox proportional hazards models were used to estimate the relationship between covariates affecting initiation and non-persistence with warfarin treatment. A total of 151,537 patients were included in the study and 5,061(3.3%) were of non-Danish origin. CHADS2 score distribution varied substantially according to ethnicity, the proportion of patients with CHADS2 score ≥1 being 79.2, 78.1, 65.9, and 46.0% for patients of Danish, Western, Eastern, and African origin, respectively. 79,239(52.4%) of all patients initiated treatment with warfarin at some point in time. Multivariable Cox proportional hazard analyses indicated patients of Eastern and African origin were less likely to initiate warfarin therapy (HR 0.75; 95% CI 0.69-0.82 and HR 0.58; 95% CI 0.44-0.76, respectively). Patients of Eastern origin were more likely to interrupt treatment (HR 1.23; 95% CI 1.02-1.47; for all patients; HR 1.62; 95% CI 1.22-2.16; for patients with CHADS2 score >1). African origin was associated with a trend to interrupt treatment (HR 1.44; 95% CI 0.46-4.47; for patients with CHADS2 score >1). Initiation of and persistence with warfarin in AF patients is lower among patients of Eastern and African origin compared to patients of Danish and Western origin, despite equal access to health care and medication. Future studies should address, beyond ethnicity, all possible driving factors of (non)initiation and persistence with treatment in general. This will be particularly interesting in light of the new generation of anticoagulants, which might render different adherence to treatment.

Not just smoking and high-tech medicine: socioeconomic inequities in U.S. mortality rates, overall and by race/ethnicity, 1960-2006

Recent research on the post-1980 widening of U.S. socioeconomic inequalities in mortality has emphasized the contribution of smoking and high-tech medicine, with some studies treating the growing inequalities as effectively inevitable. No studies, however, have analyzed long-term trends in U.S. mortality rates and inequities unrelated to smoking or due to lack of basic medical care, even as a handful have shown that U.S. socioeconomic inequalities in overall mortality shrank between the mid-1960s and 1980. The authors accordingly analyzed U.S. mortality data for 1960-2006, stratified by county income quintile and race/ethnicity, for mortality unrelated to smoking and preventable by 1960s' standards of medical care. Key findings are that relative and absolute socioeconomic inequalities in U.S. mortality unrelated to smoking and preventable by 1960s' medical care standards shrank between the 1960s and 1980 and then increased and stagnated, with absolute rates on a par with several leading causes of death, and with the burden greatest for U.S. populations of color. None of these findings can be attributed to trends in smoking-related deaths and access to high-tech medicine, and they also demonstrate that socioeconomic inequities in mortality can shrink and need not inevitably rise.

Shrinking, widening, reversing, and stagnating trends in US socioeconomic inequities in cancer mortality for the total, black, and white populations: 1960-2006

OBJECTIVES OF STUDY

To test recent claims that cancer inequities are bound to increase as population health improves.

METHODS

We analyzed 1960-2006 age-standardized US county cancer mortality data, total and site-specific (lung, prostate, colorectal, breast, cervix, stomach), stratified by county income quintile for the US total, black, and white populations.

RESULTS

Between 1960 and 2006, US socioeconomic inequities in cancer mortality variously shrunk, widened, reversed, and stagnated, depending on time period and cancer site. For all cancers combined and most, but not all, sites, absolute, but not relative, socioeconomic gaps were greater for the black compared to white population. Compared to the yearly age-specific mortality rates among whites in the most affluent counties, the percent of excess cancer deaths among whites in the lower four county income quintiles first rose above 0 in 1990 and in 2006 equaled 5.4% (95% CI 4.8, 6.0); among blacks, it rose from 6.0% (95% CI 4.5, 7.4) in 1960 to 24.7% (95% CI 23.9, 25.5) in 1990 and remained at this level through 2006.

CONCLUSIONS

The hypothesis that cancer mortality inequities are bound to increase is refuted by long-term data on total and site-specific cancer mortality stratified by socioeconomic position and race/ethnicity.

Research Challenges and Bioethics Responsibilities in the Aftermath of the Presidential Apology to the Survivors of the U. S. Public Health Services Syphilis Study at Tuskegee

In 1997 President William Clinton issued an apology to the living male survivors of the U.S. Public Health Syphilis Study at Tuskegee. While the apology became the focus for many, little attention has been paid going forward to two very important recommendations by President Clinton that accompanied the apology. President Clinton pointed out that it is through the remembering of the shameful past of the Syphilis Study at Tuskegee that we can build a better present and a better future for the nation. Second, President Clinton directed the Secretary of Health and Human Services to work in partnership with higher education to prepare training materials for medical researchers as well as postgraduate fellowships to train bioethicists to build on core ethical principles of respect for individuals, justice, and informed consent, and how to use these principles effectively in racial/ethnic minority populations, especially African Americans. This article examines bioethical research challenges left in the wake of the U.S. Public Health Syphilis Study at Tuskegee and the presidential apology. This manuscript raises for consideration the inclusion of these issues in health care reform and the implementation of the Affordable Care Act. It asks: What is the right or good thing to do? What are our obligations to one another? Two challenges are examined: 1) Conducting research with African Americans without knowledge of bioethics specific to this population; and 2) The ethical dilemma of conducting research that does not adequately take into account the diversity within the Black population that is a contributing factor in health disparities. Training and policy recommendations responsive to President Clinton's Apology are presented.

Racial/ethnic variations in substance-related disorders among adolescents in the United States

CONTEXT

While young racial/ethnic groups are the fastest growing population in the United States, data about substance-related disorders among adolescents of various racial/ethnic backgrounds are lacking.

OBJECTIVE

To examine the magnitude of past-year DSM-IV substance-related disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, and tranquilizers) among adolescents of white, Hispanic, African American, Native American, Asian or Pacific Islander, and multiple race/ethnicity.

DESIGN

The 2005 to 2008 National Survey on Drug Use and Health.

SETTING

Academic research.

PARTICIPANTS

Noninstitutionalized household adolescents aged 12 to 17 years.

MAIN OUTCOME MEASURES

Substance-related disorders were assessed by standardized survey questions administered using the audio computer-assisted self-interviewing method.

RESULTS

Of 72 561 adolescents aged 12 to 17 years, 37.0% used alcohol or drugs in the past year; 7.9% met criteria for a substance-related disorder, with Native Americans having the highest prevalence of use (47.5%) and disorder (15.0%). Analgesic opioids were the second most commonly used illegal drugs, following marijuana, in all racial/ethnic groups; analgesic opioid use was comparatively prevalent among adolescents of Native American (9.7%) and multiple race/ethnicity (8.8%). Among 27 705 past-year alcohol or drug users, Native Americans (31.5%), adolescents of multiple race/ethnicity (25.2%), adolescents of white race/ethnicity (22.9%), and Hispanics (21.0%) had the highest rates of substance-related disorders. Adolescents used marijuana more frequently than alcohol or other drugs, and 25.9% of marijuana users met criteria for marijuana abuse or dependence. After controlling for adolescents' age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of substance-related disorders among Native Americans, adolescents of multiple race/ethnicity, adolescents of white race/ethnicity, and Hispanics compared with African Americans; African Americans did not differ from Asians or Pacific Islanders.

CONCLUSIONS

Substance use is widespread among adolescents of Native American, white, Hispanic, and multiple race/ethnicity. These groups also are disproportionately affected by substance-related disorders.

Racial differences in the prevalence of overactive bladder in the United States from the epidemiology of LUTS (EpiLUTS) study

OBJECTIVES

To estimate the prevalence of overactive bladder (OAB) in men and women in the United States (US) to determine whether there were racial differences.

METHODS

This was a secondary analysis of data from the EpiLUTS (Epidemiology of Lower Urinary Tract Symptoms) survey, an Internet-based cross-sectional, population-representative epidemiologic survey conducted in the US, UK, and Sweden. These analyses were limited to the data of men and women aged 40 and older from the US. The presence of OAB was defined as experiencing urinary urgency or urinary urgency incontinence. Case definitions of OAB symptoms were categorized as occurring at least "sometimes." Prevalence rates of OAB were estimated by race. Logistic regression analyses were conducted for each gender to examine the role of race on OAB status, controlling for risk factors and comorbid conditions.

RESULTS

The response rate in the US was 59.6%. A total of 9237 men and 10,407 women self-identified their race and were included in the analytic sample. The prevalence of OAB at least "sometimes" ranged from 26% in Asian men to 33% in African American men. Similarly, the prevalence of OAB at least "sometimes" was lowest in Asian women (27%) and highest in African American women (46%). Race was predictive of OAB in men but not for women.

CONCLUSIONS

The prevalence of OAB ranged from 26-33% across races for men and from 27-46% across races for women. African American and Hispanic race is predictive of OAB for men but not for women.

The challenges of collecting data on race and ethnicity in a diverse, multiethnic state

Race and ethnicity are commonly used predictor variables in medical and public health research. Including these variables has helped researchers to describe the etiology of certain disease states. Including race and ethnicity in research has been hypothesis generating in terms of the relationship between genetic and environmental factors in the development of disease. Eliminating health disparities among different racial and ethnic groups has become a national priority. However, incorporating race and ethnicity into health research is complex because these variables are difficult to define and individuals often identify with more than one race or ethnicity. As a "minority-majority", multiethnic, multiracial state, Hawai'i faces unique challenges in incorporating race and ethnicity into research. As the demographics of the United States continue to evolve, many of the challenges faced in Hawai'i will apply to the United States as a whole.

Addressing religious and cultural differences in views on transplantation, including composite tissue allotransplantation

Composite tissue allotransplantation is a rapidly developing field in plastic and reconstructive surgery and therefore imposes an obligation upon plastic and transplant surgeons to familiarize themselves with some unique aspects of this new discipline. The visible nature of extremities, and the face, presents a special hurdle when seeking the consent of the donor's family, as well as the recipient. Religious and sociocultural backgrounds of both the donor and recipient may have an important impact on the outcome of the donation and acceptance process. The purpose of this review is to present the current positions of major religious groups on allotransplantation and the cultural responses to the religious stances. In this context, we have investigated whether there are any specific religious or cultural restrictions against the practice of composite tissue allotransplantation.

Acculturation in Hispanics and childhood poisoning: are medicines and household cleaners stored properly?

BACKGROUND

Unintentional poisonings are a major public health issue in the United States (US). With the increasing number of Hispanics in the US, childhood poisoning is a salient public health issue to address within this population. There is a paucity of research examining the relationship between acculturation in Hispanics and the safe storage of medicines and cleaners. The purpose of the study was to determine if demographic variables, such as acculturation in Hispanics, age, gender and education, were predictive of incorrectly storing medicines and household cleaners.

METHODS

We conducted a study among parents/guardians of small children at two pediatric primary care clinics in the Dallas/Fort Worth (DFW) Metropolitan area. We enrolled 201 parents to identify where they stored medicines and household cleaners, and measured acculturation with the Short Acculturation Scale for Hispanics.

RESULTS

Of Hispanic participants, 49% were categorized as less acculturated (n = 99) while 21% were more acculturated (n = 42). Less acculturated participants were over 4 times more likely to store medicines incorrectly, and participants with a high school education or less were over 3 times more likely to improperly store cleaners. With each additional child in the household, the risk for improper storage of cleaners increased by 44%.

CONCLUSION

The fact that children of less acculturated families are at greater risk for poisoning and have lower levels of education demonstrates the need for readable educational materials on this salient topic. Because social networks are integral in Hispanic culture, especially among new immigrants, poison prevention messages should be disseminated by interpersonal communications.

MEASURING EVERYDAY RACIAL/ETHNIC DISCRIMINATION IN HEALTH SURVEYS: How Best to Ask the Questions, in One or Two Stages, Across Multiple Racial/Ethnic Groups?

While it is clear that self-reported racial/ethnic discrimination is related to illness, there are challenges in measuring self-reported discrimination or unfair treatment. In the present study, we evaluate the psychometric properties of a self-reported instrument across racial/ ethnic groups in a population-based sample, and we test and interpret findings from applying two different widely-used approaches to asking about discrimination and unfair treatment. Even though we found that the subset of items we tested tap into a single underlying concept, we also found that different groups are more likely to report on different aspects of discrimination. Whether race is mentioned in the survey question affects both frequency and mean scores of reports of racial/ethnic discrimination. Our findings suggest caution to researchers when comparing studies that have used different approaches to measure racial/ethnic discrimination and allow us to suggest practical empirical guidelines for measuring and analyzing racial/ethnic discrimination. No less important, we have developed a self-reported measure of recent racial/ethnic discrimination that functions well in a range of different racial/ethnic groups and makes it possible to compare how racial/ethnic discrimination is associated with health disparities among multiple racial/ethnic groups.

The association of race, cultural factors, and health-related quality of life in persons with spinal cord injury

OBJECTIVE

To examine the association of race and cultural factors with quality-of-life factors (participation, life satisfaction, perceived health status) in people with spinal cord injury (SCI).

DESIGN

Cross-sectional multisite study using structured questionnaires.

SETTING

Six National SCI Model Systems centers.

PARTICIPANTS

People with SCI (N=275; age ≥16y; SCI with discernable neurologic impairments; used power or manual wheelchair for >1y as primary means of mobility; nonambulatory except for exercise purposes).

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Participation (Craig Handicap Assessment and Reporting Technique Short Form); satisfaction (Satisfaction With Life Scale); and perceived health status (2 items from 36-Item Short Form Health Survey).

RESULTS

African American (n=96) with SCI reported more experiences of discrimination in health care, greater perceived racism, more health care system distrust, and lower health literacy than whites (n=156; P range, <.001-<.05). Participants who reported experiencing more discrimination in health care reported better occupational functioning (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.07-2.09; P<.05). Those who perceived more racism in health care settings reported better occupational functioning (OR, 1.65; 95% CI, 1.12-2.43; P<.05) and greater perceived health (β=.36; 95% CI, .05-.68; P<.05). Those who reported more distrust in the health care system reported better current health compared with 1 year ago (β=.38; 95% CI, .06-.69; P<.05). Those who reported better communication with their health care provider reported higher levels of mobility (OR, 1.5; 95% CI, 1.05-2.13; P<.05) and better general health (β=.27; 95% CI, .01-.53; P<.05).

CONCLUSIONS

In this cross-sectional study of people with SCI, higher levels of perceived discrimination and racism and better communication with health care providers were associated with an increase in participation and functioning and improvements in perceptions of well-being. These associations are different from those reported in other study populations and warrant confirmation in future prospective studies.

Does Multiracial Matter? A Study of Racial Disparities in Self-Rated Health

How do self-identified multiracial adults fit into documented patterns of racial health disparities? We assess whether the health status of adults who view themselves as multiracial is distinctive from that of adults who maintain a single-race identity, by using a seven-year (2001–2007) pooled sample of the Behavioral Risk Factor Surveillance System (BRFSS). We explore racial differences in self-rated health between whites and several single and multiracial adults with binary logistic regression analyses and investigate whether placing these groups into a self-reported “best race” category alters patterns of health disparities. We propose four hypotheses that predict how the self-rated health status of specific multiracial groups compares with their respective component single-race counterparts, and we find substantial complexity in that no one explanatory model applies to all multiracial combinations. We also find that placing multiracial groups into a single “best race” category likely obscures the pattern of health disparities for selected groups because some multiracial adults (e.g., American Indians) tend to identify with single-race groups whose health experience they do not share.

Preliminary healthy eating outcomes of SNaX, a pilot community-based intervention for adolescents

PURPOSE

We used principles of community-based participatory research to develop and pilot test a 5-week intervention for middle school students, Students for Nutrition and eXercise (SNaX). SNaX aimed to translate school obesity-prevention policies into practice with peer advocacy of healthy eating and school cafeteria changes.

METHODS

A total 425 seventh graders (63% of all seventh graders) in the intervention school were surveyed at baseline regarding cafeteria attitudes and sugar-sweetened beverage consumption; of the 425 students, 399 (94%) were surveyed again at 1-month post-intervention. School cafeteria records were obtained from two schools: the intervention school and a nonrandomized selected comparison school with similar student socio-demographic characteristics.

RESULTS

A total of 140 students in the intervention school were trained as peer advocates. In the intervention school, cafeteria attitudes among peer advocates significantly improved over time (approximately one-third of a standard deviation), whereas cafeteria attitudes of non-peer advocates remained stable; the improvement among peer advocates was significantly greater than the pre-post-change for non-peer advocates (b = .71, p < .001). Peer advocates significantly reduced their sugar-sweetened beverage intake (sports and fruit drinks), from 33% before intervention to 21% after intervention (p = .03). Cafeteria records indicated that servings of fruit and healthier entrées (salads, sandwiches, and yogurt parfaits) significantly decreased in the comparison school and significantly increased in the intervention school; the magnitude of changes differed significantly between the schools (p < .001).

CONCLUSIONS

As compared with the non-peer advocates, peer advocates appeared to benefit more from the intervention. Future research should consider engaging parents, students, and other key community stakeholders to determine acceptable and sustainable cafeteria changes.

The association between care experiences and parent ratings of care for different racial, ethnic, and language groups in a Medicaid population

OBJECTIVE

To examine the association between care experiences and parent ratings of care within racial/ethnic/language subgroups.

DATA SOURCE

National Consumer Assessment of Healthcare Providers and Systems Benchmarking Database 3.0 (2003-2006). Sample Characteristics. 111,139 parents of minor Medicaid managed care enrollees.

STUDY DESIGN

Cross-sectional observational study predicting "poor" (0-5 on 0-10 scale) parent ratings of personal doctor, specialist, health care, and health plan from care experiences for different parent race/ethnicity/language subgroups (Latino/Spanish, Latino/English, white, and black).

PRINCIPAL FINDINGS

Care experiences had similar associations with the probability of poor parent ratings of care across the four racial/ethnic/language subgroups (p>.20). A one standard deviation improvement in the doctor communication care experience was associated with about half the frequency of poor ratings of care for personal doctor and health care in all subgroups (p<.05). Sensitivity analysis of individual communication items found that failure to provide explanations to children predicted poor ratings of care only among whites, who also weighed the length of physician interaction more heavily than other subgroups.

CONCLUSIONS

Communication-based interventions may improve experiences and ratings of care for all subgroups, although implementation of these interventions may need to consider preferences associated with race, ethnicity, and language.

Vulnerable Groups Living with Spinal Cord Injury

There is considerable variation in rehabilitation outcomes within the population of spinal cord-injured individuals across racial and socioeconomic groups. This suggests that the long-term health following spinal cord injury (SCI) is determined, at least in part, by group differences in exposure to advantages and disadvantages among persons living in the community. This article conceptualizes the nature of vulnerability and how increased vulnerability leads to disparities in SCI outcomes. Demographic, socioeconomic, and geographic determinants of adverse outcomes among vulnerable groups are discussed. Finally, a research model that outlines potential processes that elicit vulnerability following SCI and clinical implications is reviewed.

Childhood cancer in relation to parental race and ethnicity: a 5-state pooled analysis

BACKGROUND

Children of different racial/ethnic backgrounds have varying risks of cancer. However, to the authors' knowledge, few studies to date have examined cancer occurrence in children of mixed ancestry.

METHODS

This population-based case-control study examined cancer among children aged <15 years using linked cancer and birth registry data from 5 US states from 1978 through 2004. Data were available for 13,249 cancer cases and 36,996 controls selected from birth records. Parental race/ethnicity was determined from birth records. Logistic regression analysis was used to examine the association of cancer with different racial/ethnic groups.

RESULTS

Compared with whites, blacks had a 28% decreased risk of cancer (odds ratio [OR], 0.72; 95% confidence interval [95% CI], 0.65-0.80), whereas both Asians and Hispanics had an approximate 15% decrease. Children of mixed white/black ancestry also were found to be at decreased risk (OR, 0.71; 95% CI, 0.56-0.90), but estimates for mixed white/Asian and white/Hispanic children did not differ from those of whites. Compared with whites: 1) black and mixed white/black children had decreased ORs for acute lymphoblastic leukemia (OR, 0.39 [95% CI, 0.31-0.49] and OR, 0.58 [95% CI, 0.37-0.91], respectively); 2) Asian and mixed white/Asian children had decreased ORs for brain tumors (OR, 0.51 [95% CI, 0.39-0.68] and OR, 0.79 [95% CI, 0.54-1.16], respectively); and 3) Hispanic and mixed white/Hispanic children had decreased ORs for neuroblastoma (OR, 0.51 [95% CI, 0.42-0.61] and OR, 0.67 [95% CI, 0.50-0.90], respectively).

CONCLUSIONS

Children of mixed ancestry tend to have disease risks that are more similar to those of racial/ethnic minority children than the white majority group. This tendency may help formulate etiologic studies designed to study possible genetic and environmental differences more directly.

Discrimination and mental health problems among homeless minority young people

OBJECTIVE

We examined the associations among perceived discrimination, racial/ethnic identification, and emotional distress in newly homeless adolescents.

METHODS

We assessed a sample of newly homeless adolescents (n=254) in Los Angeles, California, with measures of perceived discrimination and racial/ethnic identification. We assessed emotional distress using the Brief Symptom Inventory and used multivariate linear regression modeling to gauge the impact of discrimination and racial identity on emotional distress.

RESULTS

Controlling for race and immigration status, gender, and age, young people with a greater sense of ethnic identification experienced less emotional distress. Young people with a history of racial/ethnic discrimination experienced more emotional distress.

CONCLUSION

Intervention programs that contextualize discrimination and enhance racial/ethnic identification and pride among homeless young people are needed.

Perinatal outcomes for Asian, Native Hawaiian, and other Pacific Islander mothers of single and multiple race/ethnicity: California and Hawaii, 2003-2005

OBJECTIVES

We examined characteristics and birth outcomes of Asian/Pacific Islander (API) mothers to determine whether differences in outcomes existed between mothers of single race/ethnicity and multiple race/ethnicity.

METHODS

We used data from California and Hawaii birth certificates from 2003 through 2005 to describe variation in birth outcomes for API subgroups by self-reported maternal race/ethnicity (single versus multiple race or API subgroup), and we also compared these outcomes to those of non-Hispanic White women.

RESULTS

Low birthweight (LBW) and preterm birth (PTB) varied more among API subgroups than between mothers of single versus multiple race/ethnicity. After adjustment for sociodemographic and behavioral risk factors, API mothers of multiple race/ethnicity had outcomes similar to mothers of single race/ethnicity, with exceptions for multiple-race/ethnicity Chinese (higher PTB), Filipino (lower LBW and PTB), and Thai (higher LBW) subgroups. Compared with single-race non-Hispanic Whites, adverse outcomes were elevated for most API subgroups: only single-race/ethnicity Korean mothers had lower rates of both LBW (3.4%) and PTB (5.6%); single-race/ethnicity Cambodian, Laotian, and Marshallese mothers had the highest rates of both LBW (8.8%, 9.2%, and 8.4%, respectively) and PTB (14.0%, 13.7%, and 18.8%, respectively).

CONCLUSIONS

Strategies to improve birth outcomes for API mothers should consider variations in risk by API subgroup and multiple race/ethnicity.

Workers are people too: societal aspects of occupational health disparities--an ecosocial perspective

Workers are people too. What else is new? This seemingly self-evident proposition, however, takes on new meaning when considering the challenging and deeply important issue of occupational health disparities--the topic that is the focus of 12 articles in this special issue of the American Journal of Industrial Medicine. In this commentary, I highlight some of the myriad ways that societal determinants of health intertwine with each and every aspect of occupation-related health inequities, as analyzed from an ecosocial perspective. The engagement extends from basic surveillance to etiologic research, from conceptualization and measurement of variables to analysis and interpretation of data, from causal inference to preventive action, and from the political economy of work to the political economy of health. A basic point is that who is employed (or not) in what kinds of jobs, with what kinds of exposures, what kinds of treatment, and what kinds of job stability, benefits, and pay-as well as what evidence exists about these conditions and what action is taken to address them-depends on societal context. At issue are diverse aspects of people's social location within their societies, in relation to their jointly experienced-and embodied-realities of socioeconomic position, race/ethnicity, nationality, nativity, immigration and citizen status, age, gender, and sexuality, among others. Reviewing the papers' findings, I discuss the scientific and real-world action challenges they pose. Recommendations include better conceptualization and measurement of socioeconomic position and race/ethnicity and also use of the health and human rights framework to further the public health mission of ensuring the conditions that enable people-including workers-to live healthy and dignified lives.

Ethnic disparities in accessing treatment for depression and substance use disorders in an integrated health plan

OBJECTIVE

This study examined ethnic differences in accessing treatment for depression and substance use disorders (SUDs) among men and women in a large integrated health plan, and explored factors potentially contributing to health care disparities.

METHODS

Participants were 22,543 members ages 20 to 65 who responded to health surveys in 2002 and 2005. Survey questions were linked to provider-assigned diagnoses, electronic medication, psychiatry, and chemical dependency program records.

RESULTS

Among women diagnosed with depression, Latinas (p < .01) and Asian-Americans (p < .001) were less likely than Whites to fill an antidepressant prescription. Among men diagnosed with depression, African Americans (p < .01) were less likely than Whites to do so. Among women diagnosed with an SUD, African Americans (p < .05) were less likely than Whites to have one or more chemical dependency program visits.

CONCLUSIONS

Results demonstrated ethnic differences in accessing depression and SUD treatment among patients diagnosed with these disorders, which persisted after controlling for education, income, having a regular health care provider and length of health plan enrollment. Findings highlight potential gender differences in ethnic disparities, lower antidepressant utilization among Asian Americans, and the effects of co-occurring disorders in accessing behavioral health care.

The active city? Disparities in provision of urban public recreation resources

Recreation is critical to active living yet few studies have focused on disparities in the provision of recreational programs. We investigate the spatial distribution of public recreational programs in southern California. Findings indicate that more than half of all recreation programs take place away from a formal park site. Multivariate modeling results suggest that cities characterized by low household incomes, low fiscal capacity, minority populations, and multi-family housing are disadvantaged with respect to recreation provisions. Such disparities may increase health risks among populations in such communities. Urban planners and public health advocates should enhance recreation programs in lower-income non-white communities.
