Blood Pressure Measurement Biases in Clinical Settings, Alabama, 2010-2011.

INTRODUCTION: Blood pressure measurement in clinical care settings seldom follows the protocol recommended by national guidelines, potentially leading to overestimates or underestimates of blood pressure control. We evaluated blood pressure measurement methods as a source of bias in determining blood pressure control among community-dwelling adults with diabetes. METHODS: In a community-based trial of patients with diabetes, we measured both "clinical blood pressure" (clinical BP) (taken by a community nurse or medical assistant instructed to "take the participant's blood pressure like you do in your own clinic") and "research blood pressure" (research BP) (research staff followed a guideline-concordant protocol). Each participant had both types of blood pressure assessment on the same day over the course of 2 hours. RESULTS: The 227 participants had a mean age of 59 years; 86% were black and 74% were women. The mean clinical BP was 5 mm Hg higher than the mean research BP for systolic blood pressure (P < .001) and 2 mm Hg higher for diastolic blood pressure (P < .001). The proportion of participants whose clinical BP was 130/80 mm Hg or higher was 8 percentage points higher than the proportion whose research BP was 130/80 mm Hg or higher (P < .001), and the proportion whose clinical BP was 140/90 mm Hg or higher was 10 percentage points higher than the proportion whose research BP was 140/90 mm Hg or higher (P < .001). Among those aged 65 years or older, the proportion whose clinical BP was 130/80 mm Hg or higher was 10 percentage points higher than proportion whose research BP was 130/80 mm Hg or higher, and the proportion whose clinical BP was 140/90 mm Hg or higher was 14 percentage points higher than the proportion whose research BP was 140/90 mm Hg or higher. Whites and smokers had the greatest risk for having a clinical BP 5 mm Hg or more higher than their research BP. CONCLUSION: Measurement biases in clinical settings may be a component of observed poor blood pressure control rates in real-world settings.

"We'll Get to You When We Get to You": Exploring Potential Contributions of Health Care Staff Behaviors to Patient Perceptions of Discrimination and Satisfaction.

OBJECTIVES: We qualitatively assessed patients' perceptions of discrimination and patient satisfaction in the health care setting specific to interactions with nonphysician health care staff. METHODS: We conducted 12 focus-group interviews with African American and European American participants, stratified by race and gender, from June to November 2008. We used a topic guide to facilitate discussion and identify factors contributing to perceived discrimination and analyzed transcripts for relevant themes using a codebook. RESULTS: We enrolled 92 participants: 55 African Americans and 37 European Americans, all of whom reported perceived discrimination and lower patient satisfaction as a result of interactions with nonphysician health care staff. Perceived discrimination was associated with 2 main characteristics: insurance or socioeconomic status and race. Both verbal and nonverbal communication style on the part of nonphysician health care staff were related to individuals' perceptions of how they were treated. CONCLUSIONS: The behaviors of nonphysician health care staff in the clinical setting can potentially contribute to patients' perceptions of discrimination and lowered patient satisfaction. Future interventions to reduce health care discrimination should include a focus on staff cultural competence and customer service skills.

Assessing peer advisor intervention fidelity using video skits in a peer support implementation trial.

In community-based interventions involving lay health workers, or "community health workers," peer-client interactions are not typically observed by investigators, creating challenges in assessing intervention fidelity. In the context of a community-based randomized controlled trial of the effectiveness of peer support on diabetes outcomes of people with diabetes in rural Alabama, a region characterized by poverty and low literacy, we developed a video assessment tool that assessed participant perceptions of peer-client interactions. The video assessment consisted of four short skits on areas of emphasis during peer training: directive versus nondirective counseling style and setting a specific versus a more general goal. The video tool was evaluated for association with questionnaire-derived measures of counseling style and goal setting among 102 participants. For counseling style, 44% of participants reported that their peer advisor was most similar to the nondirective skit. For goal setting, 42% reported that their peer advisor was most similar to the specific goal skit. There was no statistically significant relationship between skit selection and questionnaire-derived measures. The video assessment was feasible, but results suggest that video and questionnaire assessments in this population yield different results. Further validation to better understand the differences between questionnaire reports and video assessment is warranted.

Hospital laboratory reporting may be a barrier to detection of 'microsize' myocardial infarction in the US: an observational study.

BACKGROUND: International guidelines recommend that the decision threshold for troponin should be the 99th percentile of a normal population, or, if the laboratory assay is not sufficiently precise at this low level, the level at which the assay achieves a 10% or better coefficient of variation (CV). Our objectives were to examine US hospital laboratory troponin reports to determine whether either the 99th percentile or the 10% CV level were clearly indicated, and whether nonconcordance with these guidelines was a potential barrier to detecting clinically important microscopic or 'microsize' myocardial infarctions (MIs). To confirm past reports of the clinical importance of microsize MIs, we also contrasted in-hospital, 28-day and 1-year mortality among those with microsize and nonmicrosize MI. METHODS: In the REasons for Geographic And Racial Differences in Stroke national prospective cohort study (n=30,239), 1029 participants were hospitalized for acute coronary syndrome (ACS) between 2003-2009. For each case, we recorded all thresholds of abnormal troponin on the laboratory report and whether the 99th percentile or 10% CV value were clearly identified. All cases were expert adjudicated for presence of MI. Peak troponin values were used to classify MIs as microsize MI (< five times the lowest listed upper limit of normal) and nonmicrosize MI. RESULTS: Participants were hospitalized at 649 acute care US hospitals, only 2% of whose lab reports clearly identified the 99th percentile or the 10% CV level; 52% of reports indicated an indeterminate range, a practice that is no longer recommended. There were 183 microsize MIs and 353 nonmicrosize MIs. In-hospital mortality tended to be lower in the microsize than in the nonmicrosize MI group (1.1 vs. 3.6%, p = 0.09), but 28-day and 1-year mortality were similar (2.5% vs. 2.7% [p = 0.93] and 5.2% vs. 4.3% [p = 0.64], respectively). CONCLUSIONS: Current practices in many US hospitals created barriers to the clinical recognition of microsize MI, which was common and clinically important in our study. Improved hospital troponin reporting is warranted.

Awareness and management of chronic disease, insurance status, and health professional shortage areas in the REasons for Geographic And Racial Differences in Stroke (REGARDS): a cross-sectional study.

BACKGROUND: Limited financial and geographic access to primary care can adversely influence chronic disease outcomes. We examined variation in awareness, treatment, and control of hypertension, diabetes, and hyperlipidemia according to both geographic and financial access to care. METHODS: We analyzed data on 17,458 participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study with either hypertension, hyperlipidemia, or diabetes and living in either complete Health Professional Shortage Area (HPSA) counties or non-HPSA counties in the U.S. All analyses were stratified by insurance status and adjusted for sociodemographics and health behaviors. RESULTS: 2,261 residents lived in HPSA counties and 15,197 in non-HPSA counties. Among the uninsured, HPSA residents had higher awareness of both hypertension (adjusted OR 2.30, 95% CI 1.08, 4.89) and hyperlipidemia (adjusted OR 1.50, 95% CI 1.01, 2.22) compared to non-HPSA residents. Also among the uninsured, HPSA residents with hypertension had lower blood pressure control (adjusted OR 0.45, 95% CI 0.29, 0.71) compared with non-HPSA residents. Similar differences in awareness and control according to HPSA residence were absent among the insured. CONCLUSIONS: Despite similar or higher awareness of some chronic diseases, uninsured HPSA residents may achieve control of hypertension at lower rates compared to uninsured non-HPSA residents. Federal allocations in HPSAs should target improved quality of care as well as increasing the number of available physicians.

Intervention mapping as a guide for the development of a diabetes peer support intervention in rural Alabama.

INTRODUCTION: Peer support is a promising strategy for the reduction of diabetes-related health disparities; however, few studies describe the development of such strategies in enough detail to allow for replication. The objective of this article is to describe the development of a 1-year peer support intervention to improve diabetes self-management among African American adults with diabetes in Alabama's Black Belt. METHODS: We used principles of intervention mapping, including literature review, interviews with key informants, and a discussion group with community health workers, to guide intervention development. Qualitative data were combined with behavioral constructs and principles of diabetes self-management to create a peer support intervention to be delivered by trained peer advisors. Feedback from a 1-month pilot was used to modify the training and intervention. RESULTS: The resulting intervention includes a 2-day training for peer advisors, who were each paired with 3 to 6 clients. A one-on-one in-person needs assessment begins an intensive intervention phase conducted via telephone for 8 to 12 weeks, followed by a maintenance phase of at least once monthly contacts for the remainder of the intervention period. A peer support network and process measures collected monthly throughout the study supplement formal data collection points at baseline, 6 months, and 12 months. DISCUSSION: Intervention mapping provided a useful framework for the development of culturally relevant diabetes peer support intervention for African Americans living in Alabama's Black Belt. The process described could be implemented by others in public health to develop or adapt programs suitable for their particular community or context.

Association of race and sex with risk of incident acute coronary heart disease events.

CONTEXT: It is unknown whether long-standing disparities in incidence of coronary heart disease (CHD) among US blacks and whites persist. OBJECTIVE: To examine incident CHD by black and white race and by sex. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of 24,443 participants without CHD at baseline from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort, who resided in the continental United States and were enrolled between 2003 and 2007 with follow-up through December 31, 2009. MAIN OUTCOME MEASURE: Expert-adjudicated total (fatal and nonfatal) CHD, fatal CHD, and nonfatal CHD (definite or probable myocardial infarction [MI]; very small non-ST-elevation MI [NSTEMI] had peak troponin level <0.5 µg/L). RESULTS: Over a mean (SD) of 4.2 (1.5) years of follow-up, 659 incident CHD events occurred (153 in black men, 138 in black women, 254 in white men, and 114 in white women). Among men, the age-standardized incidence rate per 1000 person-years for total CHD was 9.0 (95% CI, 7.5-10.8) for blacks vs 8.1 (95% CI, 6.9-9.4) for whites; fatal CHD: 4.0 (95% CI, 2.9-5.3) vs 1.9 (95% CI, 1.4-2.6), respectively; and nonfatal CHD: 4.9 (95% CI, 3.8-6.2) vs 6.2 (95% CI, 5.2-7.4). Among women, the age-standardized incidence rate per 1000 person-years for total CHD was 5.0 (95% CI, 4.2-6.1) for blacks vs 3.4 (95% CI, 2.8-4.2) for whites; fatal CHD: 2.0 (95% CI, 1.5-2.7) vs 1.0 (95% CI, 0.7-1.5), respectively; and nonfatal CHD: 2.8 (95% CI, 2.2-3.7) vs 2.2 (95% CI, 1.7-2.9). Age- and region-adjusted hazard ratios for fatal CHD among blacks vs whites was near 2.0 for both men and women and became statistically nonsignificant after multivariable adjustment. The multivariable-adjusted hazard ratio for incident nonfatal CHD for blacks vs whites was 0.68 (95% CI, 0.51-0.91) for men and 0.81 (95% CI, 0.58-1.15) for women. Of the 444 nonfatal CHD events, 139 participants (31.3%) had very small NSTEMIs. CONCLUSIONS: The higher risk of fatal CHD among blacks compared with whites was associated with cardiovascular disease risk factor burden. These relationships may differ by sex.

Agreement on cause of death between proxies, death certificates, and clinician adjudicators in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study.

Death certificates may lack accuracy and misclassify the cause of death. The validity of proxy-reported cause of death is not well established. The authors examined death records on 336 participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study, a national cohort study of 30,239 community-dwelling US adults (2003-2010). Trained experts used study data, medical records, death certificates, and proxy reports to adjudicate causes of death. The authors computed agreement on cause of death from the death certificate, proxy, and adjudication, as well as sensitivity and specificity for certain diseases. Adjudicated cause of death had a higher rate of agreement with proxy reports (73%; Cohen's kappa (κ) statistic = 0.69) than with death certificates (61%; κ = 0.54). The agreement between proxy reports and adjudicators was better than agreement with death certificates for all disease-specific causes of death. Using the adjudicator assessments as the "gold standard," for disease-specific causes of death, proxy reports had similar or higher specificity and higher sensitivity (sensitivity = 50%-89%) than death certificates (sensitivity = 31%-81%). Proxy reports may be more concordant with adjudicated causes of death than with the causes of death listed on death certificates. In many settings, proxy reports may represent a better strategy for determining cause of death than reliance on death certificates.

Racial and regional differences in age at menopause in the United States: findings from the REasons for Geographic And Racial Differences in Stroke (REGARDS) study.

OBJECTIVE: We sought to examine regional and black-white differences in mean age at self-reported menopause among community-dwelling women in the United States. STUDY DESIGN: This was a cross-sectional survey conducted in the context of the REasons for Geographic And Racial Differences in Stroke and Myocardial Infarction study. RESULTS: We studied 22,484 menopausal women. After controlling for covariates, Southern women reported menopause 10.8 months earlier than Northeastern women, 8.4 months earlier than Midwestern women, and 6.0 months earlier than Western women (P < .05 for all). No difference was observed in menopausal age between black and white women after controlling for covariates (P = .69). CONCLUSION: Women in the South report earlier menopause than those in other regions, but the cause remains unclear. Our study's large sample size and adjustment for multiple confounders lends weight to our finding of no racial difference in age at menopause. More study is needed of the implications of these findings with regard to vascular health.

The association between income, education, and experiences of discrimination in older African American and European American patients.

OBJECTIVE: Racial/ethnic discrimination has adverse effects on health outcomes, as does low income and education, but the relationship between discrimination, income, and education is not well characterized. In this study, we describe the associations of discrimination with income and education in elderly African Americans (AA) and European Americans (EA). DESIGN: Cross-sectional observational study involving computer-assisted telephone survey. SETTING: Southeastern United States. PARTICIPANTS: AA and EA Medicare managed care enrollees. MAIN OUTCOME MEASURES: Discrimination was measured with the Experience of Discrimination (EOD) scale (range 0-35). We used zero-inflated negative binomial models to determine the association between self-reported income and education and 1) presence of any discrimination and 2) intensity of discrimination. RESULTS: Among 1,800 participants (45% AA, 56% female, and mean age 73 years), EA reported less discrimination than AA (4% vs. 47%; P < .001). AA men reported more discrimination and more intense discrimination than AA women (EOD scores 4.35 vs. 2.50; P < .001). Both income and education were directly and linearly associated with both presence of discrimination and intensity of discrimination in AA, so that people with higher incomes and education experienced more discrimination. In adjusted models, predicted EOD scores among AA decreased with increasing age categories (3.42, 3.21, 2.99, 2.53; P < .01) and increased with increasing income (2.36, 3.44, 4.17; P < .001) and education categories (2.31, 3.09, 5.12; P < .001). CONCLUSIONS: This study suggests future research should focus less on differences between racial/ethnic groups and more on factors within minority populations that may contribute to healthcare disparities.

Alcohol consumption in young adults and incident hypertension: 20-year follow-up from the Coronary Artery Risk Development in Young Adults Study.

The relation between alcohol consumption and incident hypertension is unclear, and most observational studies have not accounted for socioeconomic factors. This study examined the association between alcohol consumption in a diverse group of young adults and incident hypertension over 20 years. Participants (n = 4,711) were from the Coronary Artery Risk Development in Young Adults Study cohort, recruited in 1985 (aged 18-30 years) from Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California. The 20-year incidence of hypertension for never, former, light, moderate, and at-risk drinkers was 25.1%, 31.8%, 20.9%, 22.2%, and 18.8%, respectively (P < 0.001). Race, gender, age, family history of hypertension, body mass index, income, education, and difficulty paying for basics and medical care were associated with hypertension. Adjustment using Cox proportional hazard models revealed no association between baseline alcohol consumption and incident hypertension, except among European-American women in whom any current alcohol consumption was associated with lower risk of incident hypertension. The lack of association between alcohol and hypertension in the majority of this socioeconomically diverse cohort is not definitive. Future studies should include social factors, such as income and education, and consider additional characteristics that may modify or confound associations between alcohol and blood pressure.

Trust in physicians and blood pressure control in blacks and whites being treated for hypertension in the REGARDS study.

OBJECTIVES: Among persons treated for hypertension, Blacks are more likely to have uncontrolled blood pressure compared to Whites. Few studies have focused on trust in physicians as a potential contributor to this disparity in blood pressure (BP) control. The primary objective of this study was to assess the relationship between trust in physicians and blood pressure control among Blacks and Whites being treated for hypertension. DESIGN: Cross-sectional analysis of baseline data collected from the REasons for Geographic And Racial Differences in Stroke cohort, a US national, population-based cohort study. Participants were recruited by telephone from 2003-2007, completed a telephone survey, and had BP measured during an in-home visit. PARTICIPANTS: 2843 Black and White adults aged > 45 years with treated hypertension. MAIN OUTCOME MEASURES: Uncontrolled blood pressure was defined as systolic blood pressure > 140 mm Hg or diastolic blood pressure > 90 mm Hg. For participants with diabetes, renal disease, or self-reported previous myocardial infarction, uncontrolled blood pressure was defined as systolic blood pressure > 130 mm Hg or diastolic blood pressure > 80 mm Hg. RESULTS: Trust in physicians was not associated with uncontrolled blood pressure in either unadjusted (odd ratio [OR] 1.07; 95% confidence interval [CI) 0.92, 1.25) or adjusted analyses (OR 0.97; 0.83, 1.14). Both Black race (OR 1.58; 1.36, 1.84) and imperfect medication adherence (OR 1.56; 1.31,1.86) were associated with higher odds of uncontrolled blood pressure. CONCLUSIONS: Trust in physicians was not related to blood pressure control among Blacks and Whites with treated hypertension in this sample. The racial disparity in blood pressure control was not completely explained by trust in physicians or medication adherence, and a better understanding of the mechanisms leading to this disparity is needed.

Understanding racial disparities in hypertension control: intensity of hypertension medication treatment in the REGARDS study.

OBJECTIVES: African Americans (AA) suffer excess hypertension-related health outcomes and their blood pressures (BPs) are widely reported to be less controlled than European Americans (EA). Intensity of hypertension treatment may play a role. We examined whether AA with treated hypertension received less-intense medication regimens than EA, as reflected in the number of antihypertensive medication classes. DESIGN: Cross-sectional observation of baseline information from the REasons for Geographic And Racial Differences in Stroke cohort. Participants were recruited by telephone in 2003-2005, completed a telephone survey, and had BP measured and medications recorded during an in-home visit. The study's outcome was the number of classes of antihypertensive medications. SETTING: U.S. national cohort study with oversampling from high stroke mortality regions. Participants were self-identified AA or EA, > or =45 years old, living in the community, and balanced on AA race and sex by design. PARTICIPANTS: 8960 individuals with treated hypertension. RESULTS: Mean age was 68.0 +/- 8.6 years. AA were poorer and less educated than EA, and had worse BP control (63.5% BP < 140/ 90 mm Hg for AA, 74.0% for EA, P < .01), yet they were on more classes of BP medication (24.1% on > or =3 classes, vs. 16.9%, P < .01). AA were taking an average of 0.138 more antihypertensive medication classes than otherwise similar EA (P < .01). More intense treatment persisted across all age, sex, education, income and BP groups. CONCLUSIONS: AA were more intensely treated for hypertension than EA. Further study to identify action strategies to eliminate racial differences in hypertension outcomes is warranted.

Disparities in diabetes care: impact of mental illness.

BACKGROUND: Emerging evidence indicates that patients with mental health conditions (MHCs) may receive less intensive medical care. Diabetes serves as a useful condition in which to test for MHC-related disparities in care. We examined whether quality measures for diabetes care are worse for patients with or without MHCs. METHODS: This national, cross-sectional study included 313 586 noninstitutionalized Veterans Health Administration patients with diabetes (identified from diagnostic codes and prescriptions) whose Veterans Health Administration facility transmitted laboratory data to a central database; 76 799 (25%) had MHCs (based on diagnostic codes for depressed mood, anxiety, psychosis, manic symptoms, substance use disorders, personality disorders, and other categories). National data from Veterans Health Administration records, Medicare claims, and a national survey were linked to characterize 1999 diabetes care. RESULTS: Failure to meet diabetes performance measures was more common in patients with MHCs: unadjusted odds ratio (95% confidence interval) was 1.24 (1.22-1.27) for no hemoglobin A(1c) testing, 1.25 (1.23-1.28) for no low-density lipoprotein cholesterol testing, 1.05 (1.03-1.07) for no eye examination, 1.32 (1.30-1.35) for poor glycemic control, and 1.17 (1.15-1.20) for poor lipemic control. Disparities persisted after case mix adjustment and were more pronounced with specific MHCs (psychotic, manic, substance use, and personality disorders). The percentage not meeting diabetes care standards increased with increasing number of MHCs. CONCLUSION: Patients with mental illness merit special attention in national diabetes quality improvement efforts.

Acute Liver Failure after Initiation of Rivaroxaban: A Case Report and Review of the Literature.

CONTEXT: Rivaroxaban is a direct factor Xa inhibitor approved for the prevention of thromboembolism. Drug induced liver injury has been increasingly reported with rivaroxaban recently, but actual liver failure has not been reported. CASE REPORT: We present a case report on the probable occurrence of acute liver failure with rivaroxaban therapy. An 89 year old woman with history of atrial fibrillation was hospitalized for biventricular congestive heart failure with passive congestion of liver, which responded to furosemide. She was discharged home on rivaroxaban for prevention of thrombo-embolism. Liver function tests upon discharge returned to almost normal range. One week later, she presented with abdominal pain and was found to have highly elevated liver enzymes, elevated bilirubin, and an abnormal coagulation profile. A day later, she developed hepatic encephalopathy, suggesting liver failure. CONCLUSION: Liver enzymes declined rapidly with the discontinuation of all of her medications, however patient died because of multi-organ failure. The causality assessment in this patient was "probable" with rivaroxaban.

The relationship between coping styles in response to unfair treatment and understanding of diabetes self-care.

PURPOSE: This study examined the relationship between coping style and understanding of diabetes self-care among African American and white elders in a southern Medicare-managed care plan. METHODS: Participants were identified through a diabetes-related pharmacy claim or ICD-9 code and completed a computer-assisted telephone survey in 2006-2007. Understanding of diabetes self-care was assessed using the Diabetes Care Profile Understanding (DCP-U) scale. Coping styles were classified as active (talk about it/take action) or passive (keep it to yourself). Linear regression was used to estimate the associations between coping style with the DCP-U, adjusting for age, sex, education, and comorbidities. Based on the conceptual model, 4 separate categories were established for African American and white participants who displayed active and passive coping styles. RESULTS: Of 1420 participants, the mean age was 73 years, 46% were African American, and 63% were female. Most respondents (77%) exhibited active coping in response to unfair treatment. For African American participants in the study, active coping was associated with higher adjusted mean DCP-U scores when compared to participants with a passive coping style. No difference in DCP-U score was noted among white participants on the basis of coping style. CONCLUSIONS: Active coping was more strongly associated with understanding of diabetes self-care among older African Americans than whites. Future research on coping styles may give new insights into reducing diabetes disparities among racial/ethnic minorities.

Sexual health knowledge of male and female Latino immigrants.

To explore sexual health knowledge among Latino immigrants in a Southern U.S. city, we conducted 20 qualitative interviews, (10 Women and 10 Men). We explored knowledge and factors associated with sexual health among male and female Latino immigrants in a Southern U.S. city experiencing a major growth of Latino immigrants in the past 10 years. Both genders demonstrated limited knowledge of Human Papillomavirus (HPV) and risks of sexually transmitted infection (STI) acquisition. Neither gender perceived that they could have an asymptomatic STI, including HPV. Gender differences exist in sexual behaviors and perceptions of STI risk. Females indicated that female Latinas tend to have older sexual initiation age, fewer lifetime sexual partners and more pro-active sexual health than did Latinos when referring to Latino males. Consequently, male and female Latino immigrants could benefit from culturally relevant programs to alleviate STI disparities.

Recruitment of a rural, southern, predominantly African-American population into a diabetes self-management trial.

We are conducting a community-based cluster-randomized trial in rural Alabama, testing a peer-support intervention designed to improve diabetes self-care behaviors. We describe recruitment and data collection approaches used, focusing on strategies that created community partnerships and facilitated recruitment in underserved, rural, largely minority communities. Key recruitment and data collection strategies included early community engagement; pilot testing of procedures; inclusion of community members as study team members, recruiters, and data collectors; data collection at community venues to minimize participant travel requirements; and provision of a multi-disciplinary diabetes education program to both intervention and control participants. A total of 424 participants were recruited and enrolled (400 targeted). Of the 759 referrals received, 78.9% (n=599) successfully completed telephone screening. Of these, 78.8% (n=472) were eligible and scheduled for a local enrollment day, and 81.4% (n=384) attended and enrolled in the study. In addition, community members who walked in and expressed interest were screened, and 40 eligible and willing individuals were consented and enrolled. We exceeded recruitment goals in underserved, rural communities in Alabama. This success was due in large part to community partnerships that facilitated community involvement on several levels: engaging the community early in study proposal and design; hiring community members to fill various capacities as research team members, recruiters, and data collectors; conducting data collection within communities; and collecting additional contact information to maintain communication. Providing diabetes education to all participants, including intervention and control, helped ensure that everyone stood to benefit and likely enhanced overall participation.

Awareness, treatment and control of hypertension, diabetes and hyperlipidemia and area-level mortality regions in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study.

BACKGROUND: Health Professional Shortage Areas (HPSA) receive extra federal resources, but recent reports suggest that HPSA may not consistently identify areas of need. PURPOSE: To assess areas of need based on county-level ischemic heart disease (IHD) and stroke mortality regions. METHODS: Need was defined by lack of awareness, treatment, or control of hypertension, diabetes, or hyperlipidemia. Counties were categorized into race-specific tertiles of IHD and stroke mortality using 1999-2006 CDC data. Multivariable logistic regression was used to model the relationships between IHD and stroke mortality region and each element of need. RESULTS: Awareness and treatment of cardiovascular (CVD) risk factors were similar for residents in counties across IHD and stroke mortality tertiles, but control tended to be lower in counties with the highest mortality. CONCLUSIONS: High stroke and IHD mortality identify distinct regions from current HPSA designations, and may be an additional criterion for designating areas of need.

Heavy drinking is associated with poor blood pressure control in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study.

Alcohol intake has been shown to have a J-shaped association with blood pressure (BP). However, this association has not been examined in mixed race populations or in people with diabetes where tighter blood pressure control is recommended. Participants in the REGARDS study who were 45 years or older (n = 30,239) were included. Medical history (including self-reported alcohol intake) was collected by telephone while blood collection and clinical measurements were done during an in-home visit. We defined diabetes as use of medications and/or fasting glucose ≥ 126 mg/dL and hypertension as use of blood pressure lowering medications and/or BP ≥ 140/90 mmHg or BP ≥ 130/80 mmHg in people with diabetes. After adjustment for confounders, heavy drinking was associated with an increased odds of hypertension (OR = 1.59; 95% CI = 1.37, 1.87). Diabetes and gender significantly modified (interaction P < 0.05 for both) the association between alcohol use and hypertension, although heavy drinking remained associated with increased odds of hypertension in sub-group analyses. We did not observe the previously described J-shaped relationship in any sub-group except white females. These data suggest heavy alcohol consumption is associated with poor BP control and that heavy drinkers may want to consider limiting alcohol intake in order to manage hypertension.
