Race/ethnicity and outcomes following inpatient rehabilitation for hip fracture

BACKGROUND: Hip fracture results in severe and often permanent reductions in overall health and quality of life for many older adults. As the U.S. population grows older and more diverse, there is an increasing need to assess and improve outcomes across racial/ethnic cohorts of older hip fracture patients. METHODS: We examined data from 42,479 patients receiving inpatient rehabilitation for hip fracture who were discharged in 2003 from 825 facilities across the United States. Outcomes of interest included length of stay, discharge setting, and functional status at discharge and 3- to 6-month follow-up. RESULTS: Mean age was 80.2 (standard deviation [SD] = 8.0) years. A majority of the sample was non-Hispanic white (91%), followed by non-Hispanic black (4%), Hispanic (4%), and Asian (1%). After controlling for sociodemographic factors and case severity, significant (p <.05) differences between the non-Hispanic white and minority groups were observed for predicted lengths of stay in days (Asian: 1.1; 95% confidence interval [CI], 0.5-1.7; non-Hispanic black: 0.8; 95% CI, 0.6-1.1), odds of home discharge (Asian: 2.1; 95% CI, 1.6-2.8; non-Hispanic black: 2.0; 95% CI, 1.8-2.3; Hispanic: 1.9; 95% CI, 1.6-2.2), lower discharge Functional Independence Measure (FIM) ratings (non-Hispanic black: 3.6; 95% CI, 3.0-4.2; Hispanic: 1.6; 95% CI, 0.9-2.2 points lower), and lower follow-up FIM ratings (Hispanic: 4.4; 95% CI, 2.8-5.9). CONCLUSIONS: Race/ethnicity differences in outcomes were present in a national sample of hip fracture patients following inpatient rehabilitation. Recognizing these differences is the first step toward identifying and understanding potential mechanisms underlying the relationship between race/ethnicity and outcomes. These mechanisms may then be addressed to improve hip fracture care for all patients.     

Blood pressure control in Hispanics in the antihypertensive and lipid-lowering treatment to prevent heart attack trial

Historically, blood pressure control in Hispanics has been considerably less than that of non-Hispanic whites and blacks. We compared determinants of blood pressure control among Hispanic white, Hispanic black, non-Hispanic white, and non-Hispanic black participants (N=32 642) during follow-up in a randomized, practice-based, active-controlled trial. Hispanic blacks and whites represented 3% and 16% of the cohort, respectively; 33% were non-Hispanic black and 48% were non-Hispanic white. Hispanics were less likely to be controlled (<140/90 mm Hg) at enrollment, but within 6 to 12 months of follow-up, Hispanics had a greater proportion <140/90 mm Hg compared with non-Hispanics. At 4 years of follow-up, blood pressure was controlled in 72% of Hispanic whites, 69% of Hispanic blacks, 67% of non-Hispanic whites, and 59% of non-Hispanic blacks. Compared with non-Hispanic whites, Hispanic whites had a 20% greater odds of achieving BP control by 2 years of follow-up (odds ratio: 1.20; 95% CI: 1.10 to 1.31) after controlling for demographic variables and comorbidities, Hispanic blacks had a similar odds of achieving BP control (odds ratio: 1.04; 95% CI: 0.86 to 1.25), and non-Hispanic blacks had a 27% lower odds (odds ratio: 0.73; 95% CI: 0.69 to 0.78). We conclude that in all patients high levels of blood pressure control can be achieved with commonly available medications and that Hispanic ethnicity is not associated with inferior control in the setting of a clinical trial in which hypertensive patients had equal access to medical care, and medication was provided at no cost.     

Racial and ethnic disparities in cancer screening the importance of foreign birth as a barrier to care

CONTEXT: Racial/ethnic groups comprised largely of foreign-born individuals have lower rates of cancer screening than white Americans. Little is known about whether these disparities are related primarily to their race/ethnicity or birthplace. OBJECTIVE: To determine whether foreign birthplace explains some racial/ethnic disparities in cancer screening. DESIGN, SETTING, AND SUBJECTS: Cross-sectional study using 1998 data from the National Health Interview Survey. MAIN OUTCOME MEASURES: Completion of cervical, breast, or colorectal cancer screening. RESULTS: Of respondents, 15% were foreign born. In analyses adjusted for sociodemographic characteristics and illness burden, black respondents were as or more likely to report cancer screening than white respondents; however, Hispanic and Asian-American and Pacific Islander (AAPI) respondents were significantly less likely to report screening for most cancers. When race/ethnicity and birthplace were considered together, U.S.-born Hispanic and AAPI respondents were as likely to report cancer screening as U.S.-born whites; however, foreign-born white (adjusted odds ratio [AOR], 0.58; 95% confidence interval [CI], 0.41 to 0.82), Hispanic (AOR, 0.65; 95% CI, 0.53 to 0.79), and AAPI respondents (AOR, 0.28; 95% CI, 0.19 to 0.39) were less likely than U.S.-born whites to report Pap smears. Foreign-born Hispanic and AAPI respondents were also less likely to report fecal occult blood testing (FOBT); AORs, 0.72; 95% CI, 0.53 to 0.98; and 0.61; 95% CI, 0.39 to 0.96, respectively); and sigmoidoscopy (AORs, 0.70; 95% CI, 0.51 to 0.97; and 0.63; 95% CI, 0.40 to 0.99, respectively). Furthermore, foreign-born AAPI respondents were less likely to report mammography (AOR, 0.49; 95% CI, 0.28 to 0.86). Adjusting for access to care partially attenuated disparities among foreign-born respondents. CONCLUSION: Foreign birthplace may explain some disparities previously attributed to race or ethnicity, and is an important barrier to cancer screening, even after adjustment for other factors. Increasing access to health care may improve disparities among foreign-born persons to some degree, but further study is needed to understand other barriers to screening among the foreign-born.     

Factors associated with hypertension control in the general population of the United States

BACKGROUND: Uncontrolled hypertension is the most common and important risk factor for cardiovascular and renal disease. We studied factors associated with hypertension control in the Third National Health and Nutrition Examination Survey. METHODS: A total of 3077 non-Hispanic whites, 1742 non-Hispanic blacks, and 1067 Mexican Americans 18 years or older with hypertension were included in the current analysis. Blood pressure was measured by trained observers by means of a standard mercury sphygmomanometer, and controlled hypertension was defined as a mean systolic/diastolic blood pressure less than 140/90 mm Hg. RESULTS: Percentages of persons with controlled hypertension differed significantly by ethnicity and sex: 19.2% and 28.7% for white men and women, 17.5% and 28.6% for black men and women, and 12.7% and 18.0% for Mexican American men and women, respectively. After adjustment for important covariables, percentages of persons with controlled hypertension were significantly higher among persons who were currently (odds ratio [OR] 2.39; 95% confidence interval [CI], 1.52-3.74) or formerly (OR, 1.81; 95% CI, 1.12-2.93) married, had private health insurance (OR, 1.59; 95% CI, 1.02-2.49), visited the same facility for their health care (OR, 2.77; 95% CI, 1.88-4.09) or saw the same provider for their health care (OR, 2.29; 95% CI, 1.74-3.02), had their blood pressure checked during the preceding 6 months (OR, 8.00; 95% CI, 3.75-17.1) or 6 to 11 months (OR, 5.31; 2.51-11.2), and reported using lifestyle modification to control their hypertension (OR, 6.02; 95% CI, 4.20-8.63). CONCLUSION: These data strongly suggest that access to a regular source of health care and modification of lifestyle are important factors in the control of hypertension in the community.     

The association between ethnicity and late presentation to antenatal care among pregnant women living with HIV in the UK and Ireland

UK and Ireland guidelines state that all pregnant women should have their first antenatal care appointment by 13 weeks of pregnancy (antenatal booking). We present the results of an analysis looking at the association between maternal ethnicity and late antenatal booking in HIV-positive women in the UK and Ireland. We analysed data from the National Study of HIV in Pregnancy and Childhood (NSHPC). We included all pregnancies in women who were diagnosed with HIV before delivery and had an estimated delivery date between 1 January 2008 and 31 December 2009. Late booking was defined as antenatal booking at 13 weeks or later. The baseline reference group for all analyses comprised women of "white" ethnicity. Logistic regression models were fitted to estimate adjusted odds ratios (AOR). There were 2721 eligible reported pregnancies; 63% (1709) had data available on antenatal care booking date. In just over 50% of pregnancies (871/1709), the antenatal booking date was ≥13 weeks of pregnancy (i.e., late booking). Women diagnosed with HIV during the current pregnancy were more likely to present for antenatal care late than those previously diagnosed (59.1% vs. 47.5%, p<0.001). Where women knew their HIV status prior to becoming pregnant, the risk of late booking was raised for those of African ethnicity (AOR 1.80; 95% confidence interval (CI) 1.14, 2.82; p=0.011). In women diagnosed with HIV during pregnancy, the risk of late booking was also higher for women of African ethnicity (AOR 2.98: 95% CI 1.45, 6.11; p=0.003) and for women of other black ethnicity (AOR 3.74: 95% CI 1.28, 10.94; p=0.016). Overall, women of African or other black ethnicity were more likely to book late for antenatal care compared with white women, regardless of timing of diagnosis. This may have an adverse effect on maternal and infant outcomes, including mother-to-child transmission of HIV.     

Self-reported osteoarthritis, ethnicity, body mass index, and other associated risk factors in postmenopausal women-results from the Women's Health Initiative

The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)(70-79 vs 50-59)=2.69, 95% confidence interval (CI)=2.60-2.78) and higher body mass index (BMI) (OR(BMI>or=40.0 vs <24.9)=2.80, 95% CI=2.63-2.99) were found to be the strongest risk factors associated with self-reported OA. The prevalence of obesity (BMI>or=30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI>or=40.0 kg/m(2)) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity.     

The prevalence of Trichomonas vaginalis infection among reproductive-age women in the United States, 2001-2004.

BACKGROUND: Trichomonas vaginalis infection is a common sexually transmitted protozoal infection and is associated with several adverse health outcomes, such as preterm birth, delivery of a low-birth weight infant, and facilitation of sexual transmission of human immunodeficiency virus. The annual incidence in the United States has been estimated to be 3-5 million cases. However, there are no data on the prevalence of trichomoniasis among all reproductive-age women. We estimated the prevalence of T. vaginalis infection from a nationally representative sample of women in the United States. METHODS: Women aged 14-49 years who participated in the National Health and Examination Survey cycles for 2001-2004 provided self-collected vaginal swab specimens. The vaginal fluids extracted from these swabs were evaluated for the presence of T. vaginalis using polymerase chain reaction. RESULTS: Overall, 3754 (81%) of 4646 women provided swab specimens. The prevalence of T. vaginalis infection was 3.1% (95% confidence interval [CI], 2.3%-4.3%); for non-Hispanic white women, it was 1.3% (95% CI, 0.7%-2.3%); for Mexican American women, it was 1.8% (95% CI, 0.9%-3.7%); and for non-Hispanic black women, it was 13.3% (95% CI, 10.0%-17.7%). Factors that remained associated with increased likelihood of T. vaginalis infection in multivariable analyses included non-Hispanic black race/ethnicity, being born in the United States, a greater number of lifetime sex partners, increasing age, lower educational level, poverty, and douching. CONCLUSIONS: The prevalence of T. vaginalis infection among women in the United States was 3.1%. A significant racial disparity exists; the prevalence among non-Hispanic black women was 10.3 times higher than that among non-Hispanic white and Mexican American women. Optimal prevention and control strategies for T. vaginalis infection should be explored as a means of closing the racial disparity gaps and decreasing adverse health outcomes due to T. vaginalis infection.     

Effect of dysthymia on receipt of HAART by minority HIV-infected women

BACKGROUND: Receipt of highly active antiretroviral therapy (HAART) differs by gender and racial/ethnic group and may reflect an effect of mood disorders. OBJECTIVE: We examined the effects of dysthymia and major depression on HAART use by 6 groups defined by gender and race/ethnicity (white, black, Hispanic). MAIN OUTCOME MEASURE: Self-reported HAART use in the past 6 months. DATA SOURCE: Interview data from the HIV Cost and Services Utilization Study (HCSUS). Independent variables measured in or before the first half of 1997, and HAART use measured in the second half of 1997. ANALYSES: Multivariate logistic regression of depression and dysthymia on HAART use by 6 patient groups. PARTICIPANTS: One thousand nine hundred and eighty-two HIV-infected adults in HIV care in 1996 and with a CD4 count <500 in 1997. RESULTS: Highly active antiretroviral therapy receipt was the highest for white men (68.6%) and the lowest for Hispanic women (52.7%) and black women (55.4%). Dysthymia was more prevalent in women (Hispanic, 46%; black, 27%; white, 31%) than men (Hispanic, 23%; black, 18%; white, 15%). The prevalence of major depression was greater in whites (women, 35%; men, 31%) than minorities (women, 26%; men, 21%). Compared with white men without dysthymia, the adjusted odds ratios (AORs) of HAART were significantly lower for black women (0.50 [95% confidence interval [95% CI] 0.29 to 0.87]) and Hispanic women (0.45 [95% CI 0.25, 0.79]). Among patients with depression and no dysthymia, minority women had HAART use (AOR=1.28 [95% CI 0.48 to 3.43]) similar to white men. LIMITATIONS: Self-report data from the early era of HAART use; causation cannot be proven; mental health diagnoses may not meet full DSM IV criteria. CONCLUSIONS: Dysthymia is highly prevalent in minority women and associated with a 50% reduction in the odds of receiving HAART. This underrecognized condition may contribute more than depression to the "gender disparity" in HAART use.     

Aging versus disease: the opinions of older black, Hispanic, and non-Hispanic white Americans about the causes and treatment of common medical conditions.

BACKGROUND: Little is known about how older people interpret disease and how those interpretations might relate to use of medical services. OBJECTIVE: To assess opinions of older subjects about the cause and treatment of common diseases and how they are related to health behaviors. DESIGN: In-home interview of a population-based sample (n = 601) of noninstitutionalized black, Hispanic, and non-Hispanic white American men and women aged 75 and older in Galveston County, Texas. RESULTS: Substantial proportions of the subjects considered heart disease, arthritis, or difficulty sleeping to be a normal part of aging. In multivariate analyses including age, gender, education, marital status, living arrangement, global self-rating of health, and comorbidity, older black subjects were less likely to view heart disease (OR = 0.41; 95% CI, 0.26-0.64), arthritis (OR = 0.48; 95% CI, 0.31-0.73), or sleep problems (OR = 0.50; 95% CI, 0.32-0.77) as a normal part of aging than were non-Hispanic whites. Blacks were more than three times as likely to attribute heart disease to overwork or stress than were non-Hispanic whites. In multivariate analyses, subjects who considered all three of the medical conditions to be a normal part of aging ("fatalistic") were less likely to have received preventive medical services in the previous year (OR = 0.13; 95% CI, 0.02-0.96), and subjects who felt that nothing could be done to treat any of the conditions ("nihilistic") were less likely to have a regular physician (OR = 0.24; 95% CI, 0.08-0.74). CONCLUSIONS: Substantial numbers of older subjects are fatalistic about the cause of disease and/or nihilistic about its treatment. These attitudes are associated with decreased utilization of health services. Attempts to improve the health of underserved groups should employ interventions that are sensitive to the health beliefs of the targeted group.     

Ethnic variation in hypertension among premenopausal and perimenopausal women: Study of Women's Health Across the Nation

Data are sparse regarding hypertension prevalence, treatment, and control among some ethnic groups of American women. Furthermore, the effects of ethnicity on hypertension, independent of other factors that vary with ethnicity, are poorly understood. We examined the prevalence of hypertension (defined as systolic > or =140 or diastolic > or =90 mm Hg or receiving treatment), treatment, and control (to <140/<90 mm Hg) in a multiethnic study of premenopausal and perimenopausal women. Stepwise multivariable logistic regression was used to select covariates associated with hypertension. Among 3292 women, 46.9% were white, 28.3% were black, 8.7% were Hispanic, 7.6% were Chinese, and 8.5% were Japanese. Among these 5 ethnic groups, respectively, there was substantial variation in prevalence of normal blood pressure levels (<120/<80 mm Hg; 59.9%, 35.4%, 16.8%, 67.2%, and 63.7%) and hypertension (14.5%, 38.1%, 27.6%, 12.8%, and 11.0%). After multivariable adjustment, hypertension prevalence was 2 to 3x higher among black and Hispanic women but similar among Chinese and Japanese women compared with white women. Among hypertensive participants, prevalence of antihypertensive treatment was highest among blacks (58.9%) and whites (55.2%) and lowest among Chinese (34.4%). Prevalence of control to goal blood pressure levels was highest among whites (43.0%) and Japanese (38.7%) and markedly lower among Hispanic women (11.4%). Compared with whites, black and Hispanic women have significantly higher prevalence of hypertension independent of other factors, whereas Chinese and Japanese women have similar prevalence. Treatment and control rates vary considerably across ethnicities. Greater efforts must be made to improve hypertension awareness, treatment, and control in all middle-aged women, particularly those in ethnic minority groups.     

Motor vehicle crash fatalities: A comparison of Hispanic and non-Hispanic motorists in Colorado

STUDY OBJECTIVES: We compare the population-based death rates from traffic crashes in the Hispanic and non-Hispanic white populations in a single state, and compare fatally injured Hispanic and non-Hispanic drivers with respect to safety belt use, alcohol involvement, speeding, vehicle age, valid licensure, and urban-rural location. METHODS: Hispanic and non-Hispanic white motorists killed in traffic crashes in 1991-1995 were studied (n=2,272). Data from death certificates (age, sex, education, race, and ethnicity) and the Fatality Analysis Reporting System (FARS; driver, vehicle, and crash information) were merged. Average annual age-adjusted fatality rates were calculated; to compare Hispanic and non-Hispanic white motorists, rate ratios (RR) and 95% confidence intervals (CIs) were calculated. Odds ratios (ORs), adjusted for age, sex, and rural locale, were calculated to measure the association between Hispanic ethnicity and driver and crash characteristics. RESULTS: Eighty-five percent of FARS records were matched to death certificates. Compared with non-Hispanic white motorists, Hispanics had higher crash-related fatality rates overall (RR 1.75, 95% CI 1.60 to 1.92) and for drivers only (RR 1.62, 95% CI 1.41 to 1.85). After adjustment for age, sex, and rural locale, Hispanic drivers had higher rates of safety belt nonuse (OR 1.81, 95% CI 1.20 to 2.72), legal alcohol intoxication (OR 2.73, 95% CI 1.97 to 3.79), speeding (OR 1.36, 95% CI 0.99 to 1.88), and invalid licensure (OR 2.58, 95% CI 1.78 to 3.75). The average vehicle age for Hispanic drivers (10.1 years, 95% CI 9.3 to 11.0) was greater than for non-Hispanic white motorists (8.8 years, 95% CI 8.4 to 9.2). CONCLUSION: Compared with non-Hispanic whites, Hispanic drivers have higher rates of safety belt nonuse, speeding, invalid licensure and alcohol involvement, with correspondingly higher rates of death in traffic crashes. As traffic safety emerges as a public health priority in Hispanic communities, these data may help in developing appropriate and culturally sensitive interventions.     

Racial/ethnic differences in hypertension and hypertension treatment and control in the multi-ethnic study of atherosclerosis (MESA)

BACKGROUND: Most previous studies investigating the association between ethnicity and hypertension focused on differences between African Americans and whites and did not include other racial/ethnic groups such as Chinese or Hispanics. METHODS: We used data from the Multi-Ethnic Study of Atherosclerosis (MESA), a population-based study of 6814 adults without clinical cardiovascular disease, to examine the association between ethnicity and hypertension and hypertension treatment among white, African American, Chinese, and Hispanic ethnic groups. RESULTS: The prevalence of hypertension, defined as systolic blood pressure (BP) <140 mm Hg and diastolic BP <90 mm Hg or self-reported treatment for hypertension, was significantly higher in African Americans compared to whites (60% v 38%; P < .0001), whereas prevalence in Hispanic (42%) and Chinese participants (39%) did not differ significantly from that in whites. After adjustment for age, body mass index, prevalence of diabetes mellitus, and smoking, African American (odds ratio [OR] 2.21; 95% confidence interval [95% CI] 1.91-2.56) and Chinese (OR 1.30; 95% CI 1.07-1.56) ethnicity were significantly associated with hypertension compared to whites. Among hypertensive MESA participants, the percentage of treated but uncontrolled hypertension in whites (24%) was significantly lower than in African Americans (35%, P < .0001), Chinese (33%, P = .003), and Hispanics (32%, P = .0005), but only African-American race/ethnicity remained significantly associated with treated but uncontrolled hypertension after controlling for socioeconomic factors (OR 1.35; 95% CI 1.07-1.71). Diuretic use was lowest in the Chinese (22%) and Hispanic participants (32%) and was significantly lower in these groups compared with white participants (47%; P < .0001 for both comparisons). CONCLUSIONS: Programs to improve hypertension treatment and control should focus on a better understanding of differences in the prevalence of hypertension and hypertension control among minority groups in the United States, especially African Americans, compared with whites, and on techniques to prevent hypertension and improve control in high-risk groups.     

Inflammatory bowel disease characteristics among African Americans, Hispanics, and non-Hispanic Whites: characterization of a large North American cohort

OBJECTIVES: Inflammatory bowel disease (IBD), comprising primarily of Crohn's disease (CD) and ulcerative colitis (UC), is increasingly prevalent in racial and ethnic minorities. This study was undertaken to characterize racial differences in disease phenotype in a predominantly adult population. METHODS: Phenotype data on 830 non-Hispanic white, 127 non-Hispanic African American, and 169 Hispanic IBD patients, recruited from six academic centers, were abstracted from medical records and compiled in the NIDDK-IBD Genetics Consortium repository. We characterized racial differences in family history, disease location and behavior, surgical history, and extraintestinal manifestations (EIMs) using standardized definitions. RESULTS: African American CD patients were more likely than whites to develop esophagogastroduodenal CD (OR = 2.8; 95% CI: 1.4-5.5), colorectal disease (OR = 1.9; 95% CI: 1.1-3.4), perianal disease (OR = 1.7; 95% CI: 1.03-2.8), but less likely to have ileal involvement (OR = 0.55; 95% CI: 0.32-0.96). They were also at higher risk for uveitis (OR = 5.5; 95% CI: 2.3-13.0) and sacroiliitis (OR = 4.0; 95% CI: 1.55-10.1). Hispanics had higher prevalence of perianal CD (OR = 2.9; 95% CI: 1.8-4.6) and erythema nodosum (3.3; 95% CI: 1.7-6.4). Among UC patients, Hispanics had more proximal disease extent. Both African American and Hispanic CD patients, but not UC patients, had lower prevalences of family history of IBD than their white counterparts. CONCLUSIONS: There are racial differences in IBD family history, disease location, and EIMs that may reflect underlying genetic variations and have important implications for diagnosis and management of disease. These findings underscore the need for further studies in minority populations.     

Prevalence of SEN viruses among injection drug users in the San Francisco Bay area

SEN viruses (SENVs) are newly discovered bloodborne viruses that may play a role in liver disease. SENV strain prevalence was examined in a race/ethnicity-stratified sample of 531 injection drug users (IDUs) from the San Francisco Bay area. Weighted prevalences were as follows: SENV-A, 45.7%; SENV-C/H, 35.6%; and SENV-D, 10.3%. Infection was associated with a longer duration of injection drug use. SENV-A was more common in black subjects (adjusted odds ratio [OR(a)], 4.37; 95% confidence interval [CI], 2.65-7.21) and Hispanic subjects (OR(a), 2.30; 95% CI, 1.38-3.85) than in white and non-Hispanic subjects, and the pattern was similar for SENV-C/H. For SENV-D, prevalence was similar in black and white subjects, but lower in Hispanic subjects; infection was less common among women than men (OR(a), 0.32; 95% CI, 0.15-0.71) and more common among men with at least 1 recent male sex partner than among heterosexual men (OR(a), 7.05; 95% CI, 2.62-18.95). SENV strains are common among San Francisco Bay area IDUs, and prevalence varies demographically within this group.     

Hypertension treatment in the ambulatory setting: comparison by race and gender in a national survey

To determine if different therapies are used in different racial groups and by gender, data from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Care Survey (national probability samples of outpatient visits) were used. All visits for hypertension in 1999 and 2000 were reviewed. Survey weights were applied to obtain national estimates. Provision of therapies by gender and race/ethnicity (white, African American, Hispanic, Asian) was examined. Over 137 million visits for hypertension care were made during 1999 and 2000. Diet and exercise counseling were performed at a low percentage of visits (35% and 26% of visits, respectively). The most common antihypertensive agent prescribed was angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers (28%), while first-line drugs, diuretics (23%) and b blockers (15%), which are recommended by national committees, were prescribed less frequently. Asians and Hispanics were more likely to receive counseling on diet (Asians: odds ratio [OR], 2.29; 95% confidence interval [CI], 1.45-3.60; Hispanics: OR, 2.51; 95% CI, 1.18-5.33) and exercise (Asians: OR, 2.44; 95% CI, 1.35-4.42; Hispanics: OR, 3.28; 95% CI, 1.50-7.21) than non-Hispanic whites. African Americans were more likely to be prescribed calcium channel blockers (OR, 1.51; 95% CI, 1.20-1.91) and diuretics (OR, 1.37; 95% CI, 1.08-1.74). Low use of recommended therapies was found. Although variation by race was seen, it did not systematically favor groups associated with poor outcomes.     

Comorbid hypertension and diabetes among U.S. women of reproductive age: Prevalence and disparities

Aims

Diabetes is associated with significant pregnancy complications, which can be further exacerbated by comorbid hypertension. Racial/ethnic differentials in the burden of comorbid hypertension and diabetes among women of reproductive age have not been described.

Hypertension labelling was associated with poorer self-rated health in the Third US National Health and Nutrition Examination Survey

Individuals labelled as having hypertension tend to report poor self-rated health (SRH), but it is unclear whether this association is independent of actual hypertension, socioeconomic status and adiposity, and extends across racial and ethnic groups. In a cross-sectional study we compared hypertensive and normotensive individuals (N = 19,057) who varied in whether they had ever been labelled hypertensive. Blood pressure was measured in participants' homes and mobile examination centres in the United States as part of the Third National Health and Nutrition Examination Survey, 1988-1994. The main outcome measure was global SRH. Hypertensive labelling was associated with poorer SRH and was independent of established SRH predictors, antihypertensive medication use, body mass index, and hypertension status (adjusted odds ratio (OR) = 1.79, 95% confidence interval (CI), 1.61-1.99). Hypertension was also associated with poorer SRH (OR = 1.26; 95% CI 1.09-1.46) but this association was eliminated by adjustment for hypertensive labelling (OR 1.06; 95% CI 0.92-1.22). These effects were consistent across non-Hispanic white, non-Hispanic black, and Hispanic subgroups. Individuals labelled hypertensive are more likely to have lower SRH and this labelling effect predominates over that of actual hypertension. Public health efforts to increase the number of individuals screened for high blood pressure may successfully detect the presence of hypertension but may also reduce health-related quality of life as measured by global SRH.     

Sexual risk behaviours and sexual health outcomes among heterosexual black Caribbeans: comparing sexually transmitted infection clinic attendees and national probability survey respondents

We compared sociodemographic characteristics, sexual risk behaviours and sexual health experiences of 266 heterosexual black Caribbeans recruited at a London sexual health clinic between September 2005 and January 2006 with 402 heterosexual black Caribbeans interviewed for a British probability survey between May 1999 and August 2001. Male clinic attendees were more likely than men in the national survey to report: ≥10 sexual partners (lifetime; adjusted odds ratio [AOR]: 3.27, 95% confidence interval [CI]: 1.66-6.42), ≥2 partners (last year; AOR: 5.40, 95% CI: 2.64-11.0), concurrent partnerships (AOR: 3.26, 95% CI: 1.61-6.60), sex with partner(s) from the Caribbean (last 5 years; AOR: 7.97, 95% CI: 2.42-26.2) and previous sexually transmitted infection (STI) diagnosis/diagnoses (last 5 years; AOR: 16.2, 95% CI: 8.04-32.6). Similar patterns were observed for women clinic attendees, who also had increased odds of termination of pregnancy (AOR: 3.25, 95% CI: 1.87-5.66). These results highlight the substantially higher levels of several high-risk sexual behaviours among UK black Caribbeans attending a sexual health clinic compared with those in the general population. High-risk individuals are under-represented in probability samples, and it is therefore important that convenience samples of high-risk individuals are performed in conjunction with nationally representative surveys to fully understand the risk behaviours and sexual health-care needs of ethnic minority communities.     

Ethnic disparities in stroke and hypertension among women: the BASIC project

BACKGROUND: Little data exist on stroke burden in Mexican-American (MA) women. The objective of this study was to characterize the burden of stroke in MA and non-Hispanic white (NHW) women and to compare this burden across ethnic groups. METHODS: Cases of ischemic stroke and intracerebral hemorrhage among women (January 2000-December 2006) were identified as part of the Brain Attack Surveillance in Corpus Christi (BASIC) Project, a stroke surveillance study in a biethnic Texas community. Cumulative incidence of stroke among women was compared by ethnicity and age. Logistic regression was used to compare risk factors and age-adjusted use of antihypertensives between MA and NHW female stroke cases. RESULTS: MA women had elevated stroke risk compared with NHW women at younger ages (ages 45-59: relative risk (RR) = 2.00 (95% confidence interval (CI): 1.54-2.58); ages 60-74: RR = 1.57 (95% CI: 1.31-1.87); ages > or =75: RR = 1.13 (95% CI: 0.98-1.29)). Stroke severity and stroke type did not differ between ethnic groups. MA female stroke cases were more likely to have hypertension (odds ratio (OR) = 1.41 (95% CI: 1.11-1.80)), diabetes (OR = 3.54 (95% CI: 2.82-4.45)), and the presence of both risk factors (OR = 3.31 (95% CI: 2.61-4.21)) compared with NHW female stroke cases and were more likely to report use of antihypertensives (OR = 1.51 (95% CI: 1.10-2.06)). There was a trend toward greater hypertension awareness among MA female stroke cases (OR = 1.37 (95% CI: 0.98-1.91)). CONCLUSIONS: MA women have increased risk of stroke at younger ages compared with NHW women. Reasons for this ethnic disparity, including an increased prevalence of hypertension and diabetes, should be explored.
