The Effects of Ethnicity and Language on Medical Outcomes of Patients with Hypertension or Diabetes

Limited research has compared the wellbeing functioning of patients from different ethnic backgrounds with chronic medical conditions. Given that ethnic differences in attitudes, beliefs, and behavior have been reported on health-related issues such as cigarette smoking and cancer, patient reports of well-being and functioning and other outcomes also may differ by ethnicity because of cultural factors.1-4 Cultural factors may affect a patients communication with their physician and, as a result, influence health outcomes. Kaplan et a15 found that effectiveness of information gathering by patients, more conversation by patients relative to physicians, and more affective exchange between patients and physicians were specific aspects of patient-physician communication associated with better

Physician Language Ability and Cultural Competence: An Exploratory Study of Communication with Spanish-speaking Patients

AbstractOBJECTIVE: We studied physician-patient dyads to determine how physician self-rated Spanish-language ability and cultural competence affect Spanish-speaking patients’ reports of interpersonal processes of care. SETTING/PARTICIPANTS: Questionnaire study of 116 Spanish-speaking patients with diabetes and 48 primary care physicians (PCPs) at a public hospital with interpreter services. MEASURES: Primary care physicians rated their Spanish ability on a 5-point scale and cultural competence by rating: 1) their understanding of the health-related cultural beliefs of their Spanish-speaking patients; and 2) their effectiveness with Latino patients, each on a 4-point scale. We assessed patients’ experiences using the interpersonal processes of care (IPC) in diverse populations instrument. Primary care physician responses were dichotomized, as were IPC scale scores (optimal vs nonoptimal). We analyzed the relationship between language and two cultural competence items and IPC, and a summary scale and IPC, using multivariate models to adjust for known confounders of communication. RESULTS: Greater language fluency was strongly associated with optimal IPC scores in the domain of elicitation of and responsiveness to patients, problems and concerns [Adjusted Odds Ratio [AOR], 5.25; 95% confidence interval [CI], 1.59 to 17.27]. Higher score on a language-culture summary scale was associated with three IPC domains — elicitation/responsiveness (AOR, 6.34; 95% CI, 2.1 to 19.3), explanation of condition (AOR, 2.7; 95% CI, 1.0 to 7.34), and patient empowerment (AOR, 3.13; 95% CI, 1.2 to 8.19)—and not associated with two more-technical communication domains. CONCLUSION: Physician self-rated language ability and cultural competence are independently associated with patients’ reports of interpersonal process of care in patient-centered domains. Our study provides empiric support for the importance of language and cultural competence in the primary care of Spanish-speaking patients.

Latino Populations: A Unique Opportunity for the Study of Race, Genetics, and Social Environment in Epidemiological Research

Latinos are the largest minority population in the United States. Although usually classified as a single ethnic group by researchers, Latinos are heterogeneous from cultural, socioeconomic, and genetic perspectives. From a cultural and social perspective, Latinos represent a wide variety of national origins and ethnic and cultural groups, with a full spectrum of social class. From a genetic perspective, Latinos are descended from indigenous American, European, and African populations. We review the historical events that led to the formation of contemporary Latino populations and use results from recent genetic and clinical studies to illustrate the unique opportunity Latino groups offer for studying the interaction between racial, genetic, and environmental contributions to disease occurrence and drug response.

Cigarette Smoking Behavior Among US Latino Men and Women From Different Countries of Origin

OBJECTIVES This study sought to compare smoking behavior among Latino men and women from different countries of origin. METHODS A telephone-administered survey was conducted in 8 cities with Latino men and women of different national origin living in census tracts with at least 70% Latino individuals. RESULTS A total of 8882 participants completed the survey; 53% were women. The average age of respondents was 44 years; 63% were foreign-born, and 59% preferred Spanish for the interview. Current smoking was more prevalent among men (25.0%, 95% confidence interval [CI] = 23.7, 26.3) than among women (12.1%, 95% CI = 11.1, 13.0). Smoking rates were not significantly different by national origin among men, but Puerto Rican women had higher rates of smoking than other women. Central American men and women had the lowest smoking rates. Foreign-born respondents were less likely to be smokers (odds ratio [OR] = 0.77, 95% CI = 0.66, 0.90) than US-born respondents, and respondents with 12 years or less of education had an increased odds of smoking (OR = 1.17, 95% CI = 1.01, 1.35). High ac culturation was associated with more smoking in women (OR = 1.12, 95% CI = 1.00-1.25) and less smoking in men (OR = 0.86, 95% CI = 0.78-0.95). Puerto Rican and Cuban respondents were more likely to be current smokers and to smoke more than 20 cigarettes per day. CONCLUSIONS Older, US-born, and more-educated respondents were less likely to be current smokers. Respondents of Puerto Rican and Cuban origin were more likely to smoke. Acculturation has divergent effects on smoking behavior by sex.

Cigarette smoking among San Francisco Hispanics: the role of acculturation and gender.

We conducted a phone survey of 1,669 San Francisco Hispanics ages 15 to 64 years. The age-adjusted overall smoking prevalence was 25.4 per cent (95% CI = 23.3, 27.5) with more men (32.4 per cent) smoking than women (16.8 per cent). Age-adjusted smoking rates were higher among the less acculturated males (37.5 vs 26.7 per cent) and among the more acculturated females (22.6 vs 13.6 per cent). The more acculturated, however, smoked a greater number of cigarettes per day independent of gender. Community-based smoking cessation interventions, adapted to local conditions, may have a greater potential for success among Hispanics.

Population stratification confounds genetic association studies among Latinos

In the United States, asthma prevalence and mortality are the highest among Puerto Ricans and the lowest among Mexicans. Case-control association studies are a powerful strategy for identifying genes of modest effect in complex diseases. However, studies of complex disorders in admixed populations such as Latinos may be confounded by population stratification. We used ancestry informative markers (AIMs) to identify and correct for population stratification among Mexican and Puerto Rican subjects participating in case-control studies of asthma. Three hundred and sixty-two subjects with asthma (Mexican: 181, Puerto Rican: 181) and 359 ethnically matched controls (Mexican: 181, Puerto Rican: 178) were genotyped for 44 AIMs. We observed a greater than expected degree of association between pairs of AIMs on different chromosomes in Mexicans (P<0.00001) and Puerto Ricans (P<0.00002) providing evidence for population substructure and/or recent admixture. To assess the effect of population stratification on association studies of asthma, we measured differences in genetic background of cases and controls by comparing allele frequencies of the 44 AIMs. Among Puerto Ricans but not in Mexicans, we observed a significant overall difference in allele frequencies between cases and controls (P=0.0002); of 44 AIMs tested, 8 (18%) were significantly associated with asthma. However, after adjustment for individual ancestry, only two of these markers remained significantly associated with the disease. Our findings suggest that empirical assessment of the effects of stratification is critical to appropriately interpret the results of case-control studies in admixed populations.

Prevention of depression with primary care patients: A randomized controlled trial

The prevention of major depression is an important research goal which deserves increased attention. Depressive symptoms and disorders are particularly common in primary care patients and have a negative impact on functioning and well-being comparable with other major chronic medical conditions. The San Francisco Depression Prevention Research project conducted a randomized, controlled, prevention trial to demonstrate the feasibility of implementing such research in a public sector setting serving low-income, predominantly minority individuals: 150 primary care patients free from depression or other major mental disorders were randomized to an experimental cognitive-behavioral intervention or to a control condition. The experimental intervention group reported a significantly greater reduction in depressive levels. Decline in depressive levels was significantly mediated by decline in the frequency of negative conditions. Group differences in the number of new episodes (incidence) of major depression did not reach significance during the 1-year trial. We conclude that depression prevention trials in public sector primary care settings are feasbile, and that depressive symptoms can be reduced even in low-income, minority populations. To conduct randomized prevention trials that can test effects on incidence with sufficient statistical power, subgroups at greater imminent risk have to be identified.

Interpersonal Processes of Care in Diverse Populations

Persons of lower socioeconomic status and members of racial and ethnic minority groups experience poorer health and increased health risk factors. A framework of interpersonal processes of care specifies distinct components and incorporates the perspective of diverse racial and ethnic or socioeconomic groups. Its dimensions, each with several domains, are communication (general clarity, elicitation of and responsiveness to patient concerns, explanations, empowerment), decision making (responsiveness to patient preferences, consideration of ability and desire to comply), and interpersonal style (friendliness, respectfulness, discrimination, cultural sensitivity, support). All the domains, except cultural sensitivity, were validated through a survey of 603 ethnically diverse, low-income adults. Confirmation of the frameworks usefulness should enable researchers to explore how interpersonal processes might account for observed ethnic and social class differences in health care and health.

A Nationwide Analysis of US Racial/Ethnic Disparities in Smoking Behaviors, Smoking Cessation, and Cessation-Related Factors

OBJECTIVES We used nationally representative data to examine racial/ethnic disparities in smoking behaviors, smoking cessation, and factors associated with cessation among US adults. METHODS We analyzed data on adults aged 20 to 64 years from the 2003 Tobacco Use Supplement to the Current Population Survey, and we examined associations by fitting adjusted logistic regression models to the data. RESULTS Compared with non-Hispanic Whites, smaller proportions of African Americans, Asian Americans/Pacific Islanders, and Hispanics/Latinos had ever smoked. Significantly fewer African Americans reported long-term quitting. Racial/ethnic minorities were more likely to be light and intermittent smokers and less likely to smoke within 30 minutes of waking. Adjusted models revealed that racial/ethnic minorities were not less likely to receive advice from health professionals to quit smoking, but they were less likely to use nicotine replacement therapy. CONCLUSIONS Specific needs and ideal program focuses for cessation may vary across racial/ethnic groups, such that approaches tailored by race/ethnicity might be optimal. Traditional conceptualizations of cigarette addiction and the quitting process may need to be revised for racial/ethnic minority smokers.

Breast and Cervical Cancer Screening: Impact of Health Insurance Status, Ethnicity, and Nativity of Latinas

PURPOSE Although rates of cancer screening for Latinas are lower than for non-Latina whites, little is known about how insurance status, ethnicity, and nativity interact to influence these disparities. Using a large statewide database, our study examined the relationship between breast and cervical cancer screening rates and socioeconomic and health insurance status among foreign-born Latinas, US-born Latinas, and non-Latina whites in California. METHODS Data from the1998 California Women’s Health Survey (CWHS) were analyzed (n = 3,340) using multiple logistic regression models. Utilization rates of mammography, clinical breast examinations, and Papanicolaou (Pap) smear screening among foreign-born Latinas, US-born Latinas, and non-Latina whites were the outcome measures. RESULTS Foreign-born Latinas had the highest rates of never receiving mammography, clinical breast examinations, and Pap smears (21%, 24%, 9%, respectively) compared with US-born Latinas (12%, 11%, 7%, respectively) and non-Latina whites (9%, 5%, 2%, respectively). After controlling for socioeconomic factors, foreign-born Latinas were more likely to report mammography use in the previous 2 years and Pap smear in the previous 3 years than non-Latina whites. Lack of health insurance coverage was the strongest independent predictor of low utilization rates for mammography (odds ratio [OR] = 2.05; 95% confidence interval [CI], 1.53–2.76), clinical breast examinations (OR = 2.29; 95% CI, 1.80–2.90) and Pap smears (OR = 2.89; 95% CI, 2.17–3.85.) CONCLUSIONS Breast and cervical cancer screening rates vary by ethnicity and nativity, with foreign-born Latinas experiencing the highest rates of never being screened. After accounting for socioeconomic factors, differences by ethnicity and nativity are reversed or eliminated. Lack of health insurance coverage remains the strongest predictor of cancer screening underutilization.
