249-256AbstractDespite strong evidence of effective interventions targeted at blood pressure (BP) control, there is little evidence on the translation of these approaches to routine clinical practice in care of hypertensive blacks. The goal of this study is to evaluate the effectiveness of a multilevel, multicomponent, evidence-based intervention compared with usual care in improving BP control among hypertensive blacks who receive care in community health centers. The primary outcomes are BP control rate at 12 months and maintenance of intervention 1 year after the trial. The secondary outcomes are within-patient change in BP from baseline to 12 months and cost-effectiveness of the intervention. Counseling African Americans to Control Hypertension (CAATCH) is a group randomized clinical trial with 2 conditions: intervention condition and usual care. Thirty community health centers were randomly assigned equally to the intervention condition group (n=15) or the usual care group (n=15). The intervention comprises 3 components targeted at patients (interactive computerized hypertension education, home BP monitoring, and monthly behavioral counseling on lifestyle modification) and 2 components targeted at physicians (monthly case rounds based on Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure guidelines, chart audit and provision of feedback on clinical performance and patients' home BP readings). All outcomes are assessed at quarterly study visits for 1 year. Chart review is conducted at 24 months to evaluate maintenance of intervention effects and sustainability of the intervention. Poor BP control is one of the major reasons for the mortality gap between blacks and whites. Findings from this study, if successful, will provide salient information needed for translation and dissemination of evidence-based interventions targeted at BP control into clinical practice for this high-risk population.

238-242AbstractDiabetes is a major public health problem that is reaching epidemic proportions in the United States and worldwide. Over 22 million Americans currently have diabetes and it is forecast that over 350 million people worldwide will be affected by 2030. Furthermore, the economic cost of diabetes care is enormous. Despite current efforts on the part of health care providers and their patients, outcomes of care remain largely suboptimal, with only 3% to 7% of the entire diabetes population meeting recommended treatment goals for glycemic, blood pressure, and lipid control. Therefore, alternative approaches to diabetes care are desperately needed. Group visits may provide a viable option for patients and health care providers, with the potential to improve outcomes and cost effectiveness. In this review, we highlight the magnitude of the diabetes epidemic, the barriers to optimal diabetes care, and the utility of the concept of group visits as a chronic disease management strategy for diabetes care.Lifestyle changes and blood pressure control: A community-based cross-sectional survey (2006 Ontario survey on the prevalence and control of hypertension)

909-916AbstractObjective: To investigate differences in overweight and obesity between first-generation Dutch-Ghanaian migrants in The Netherlands and their rural and urban counterparts in Ghana. Design: Cross-sectional study. Subjects: A total of 1471 Ghanaians (rural Ghanaians, n 532; urban Ghanaians, n 787; Dutch-Ghanaians, n 152) aged ≥17 years. Main outcome measures: Overweight (BMI ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2). Results: Dutch-Ghanaians had a significantly higher prevalence of overweight and obesity (men 69.1 %, women 79.5 %) than urban Ghanaians (men 22.0 %, women 50.0 %) and rural Ghanaians (men 10.3 %, women 19.0 %). Urban Ghanaian men and women also had a significantly higher prevalence of overweight and obesity than their rural Ghanaian counterparts. In a logistic regression analysis adjusting for age and education, the odds ratios for being overweight or obese were 3.10 (95 % CI 1.75, 5.48) for urban Ghanaian men and 19.06 (95 % CI 8.98, 40.43) for Dutch-Ghanaian men compared with rural Ghanaian men. Among women, the odds ratios for being overweight and obese were 3.84 (95 % CI 2.66, 5.53) for urban Ghanaians and 11.4 (95 % CI 5.97, 22.07) for Dutch-Ghanaians compared with their rural Ghanaian counterparts. Conclusion: Our current findings give credence to earlier reports of an increase in the prevalence of overweight/obesity with urbanization within Africa and migration to industrialized countries. These findings indicate an urgent need to further assess migration-related factors that lead to these increases in overweight and obesity among migrants with non-Western background, and their impact on overweight- and obesity-related illnesses such as diabetes among these populations.Predictors of first-fill adherence for patients with hypertension

637-642AbstractBackground: Reduced nocturnal blood pressure (BP) dipping is more prevalent among blacks living in the United States than whites and is associated with increased target organ damage and cardiovascular risk. The primary aim of this study was to determine whether socioeconomic and psychosocial factors help to explain racial differences in dipping. In order to address the limited reproducibility of dipping measures, we investigated this question in a sample of participants who underwent multiple ambulatory BP monitoring (ABPM) sessions. Methods: The study sample included 171 black and white normotensive and mildly hypertensive participants who underwent three ABPM sessions, each 1 month apart, and completed a battery of questionnaires to assess socioeconomic and psychosocial factors. Results: As expected, blacks showed less dipping than whites, after adjusting for age, sex, body mass index (BMI), and mean 24-h BP level (mean difference = 3.3%, P = 0.002). Dipping was related to several of the socioeconomic and psychosocial factors examined, with higher education and income, being married, and higher perceived social support, each associated with a larger dipping percentage. Of these, marital status and education were independently associated with dipping and together accounted for 36% of the effect of race on dipping. Conclusions: We identified a number of socioeconomic and psychosocial correlates of BP dipping and found that reduced dipping among blacks vs. whites is partially explained by marital status (being unmarried) and lower education among blacks. We also present results suggesting that repeated ABPM may facilitate the detection of associations between dipping and other variables.Strategies for implementing and sustaining therapeutic lifestyle changes as part of hypertension management in African Americans

147-159AbstractAfrican Americans with high blood pressure (BP) can benefit greatly from therapeutic lifestyle changes (TLC) such as diet modification, physical activity, and weight management. However, they and their health care providers face many barriers in modifying health behaviors. A multidisciplinary panel synthesized the scientific data on TLC in African Americans for efficacy in improving BP control, barriers to behavioral change, and strategies to overcome those barriers. Therapeutic lifestyle change interventions should emphasize patient self-management, supported by providers, family, and the community. Interventions should be tailored to an individual's cultural heritage, beliefs, and behavioral norms. Simultaneously targeting multiple factors that impede BP control will maximize the likelihood of success. The panel cited limited progress with integrating the Dietary Approaches to Stop Hypertension (DASH) eating plan into the African American diet as an example of the need for more strategically developed interventions. Culturally sensitive instruments to assess impact will help guide improved provision of TLC in special populations. The challenge of improving BP control in African Americans and delivery of hypertension care requires changes at the health system and public policy levels. At the patient level, culturally sensitive interventions that apply the strategies described and optimize community involvement will advance TLC in African Americans with high BP.What is the optimal interval between successive home blood pressure readings using an automated oscillometric device?

826-839AbstractPatients who have undergone angioplasty experience difficulty modifying at-risk behaviors for subsequent cardiac events. The purpose of this study was to test whether an innovative approach to framing of risk, based on 'net present value' economic theory, would be more effective in behavioral intervention than the standard 'future value approach' in reducing cardiovascular morbidity and mortality following angioplasty. At baseline, all patients completed a health assessment, recieved an individualized risk profile and selected risk factors for modification. The intervention randomized patients into two varying methods for illustrating positive effects of behavior change. For the experimental group, each selected risk factor was assigned a numeric biologic age (the net present value) that approximated the relative potential to improve current health status and quality of life when modifying that risk factor. In the control group, risk reduction was framed as the value of preventing future health problems. Ninety-four percent of patients completed 2-year follow-up. There was no difference between the rates of death, stroke, myocardial infarction, Class II-IV angina or severe ischemia (on non-invasive testing) between the net present value group and the future value group. Our results show that a net present risk communication intervention did not result in significant differences in health outcomes.
