The diagnosis of masked hypertension has been made easier with the widespread availability of home blood pressure monitoring devices with levels of accuracy comparable to ambulatory blood pressure monitoring. The negative impact of masked hypertension on cardiovascular morbidity and mortality is evidenced by numerous well-designed clinic-based and population-based studies. The relationship of masked hypertension and target organ damage is also well documented. These two factors, combined with the robust evidence of reduced cardiovascular morbidity and mortality achieved with blood pressure treatment, makes the argument for actively identifying patients with masked hypertension and prescribing treatment similar to that for patients with sustained hypertension. In this paper, we review the evidence for the cardiovascular prognosis of masked hypertension compared with sustained hypertension, we review its impact on target organ damage, we propose an algorithm for the treatment of patients with masked hypertension, and we point out the pitfalls in adopting such an approach

OBJECTIVE: To apply qualitative research methods in developing a culturally tailored, educational workbook for hypertensive black patients. METHODS: The workbook was developed using formative qualitative data from 60 black primary care patients with hypertension. Participants were interviewed using qualitative methods and data were analyzed through sequential steps of open coding, axial coding, and selective coding. From these analyses, themes describing patients' cultural beliefs about hypertension were derived and used to develop the workbook. RESULTS: The workbook, 'Living With Hypertension: Taking Control' is a 37-page illustrated workbook with 11 chapters based on patients' perceptions of hypertension. These chapters focus on strengthening participants' ability to take control and manage hypertension and on providing knowledge and health behavior techniques. CONCLUSION: Qualitative research methods were used to inform the development of a culturally tailored educational workbook. PRACTICE IMPLICATIONS: The workbook developed in this study may offer a practical and effective means of educating patients about blood pressure control in primary care settings

BACKGROUND: Barbershops constitute potential sites for community health promotion programs targeting hypertension (HTN) in African American men but such programs previously have not been formally evaluated. METHODS: A randomized trial (ClinicalTrials.gov no. NCT00325533) will test whether a continuous HTN detection and medical referral program conducted by influential peers (barbers) in a receptive community setting (barbershops) can promote treatment-seeking behavior and thus lower blood pressure (BP) among the regular customers with HTN. Barbers will offer a BP check with each haircut and encourage appropriate medical referral using real stories of other customers modeling the desired behaviors. A cohort of 16 barbershops will go through a pretest/posttest group-randomization protocol. Serial cross-sectional data collection periods (10 weeks each) will be conducted by interviewers to obtain accurate snapshots of HTN control in each barbershop before and after 10 months of either barber-based intervention or no active intervention. The primary outcome is BP control: BP <135/85 mm Hg (nondiabetic subjects) and <130/80 mm Hg (diabetic subjects) measured in the barbershop during the 2 data collection periods. The multilevel analysis plan uses hierarchical models to assess the effect of covariates on HTN control and secondary outcomes while accounting for clustering of observations within barbershops. CONCLUSIONS: By linking community health promotion to the health care system, this program could serve as a new model for HTN control and cardiovascular risk reduction in African American men on a nationwide scale

Despite 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

BACKGROUND: Hypertension (HTN) control rates in the United States remain lower in black than white persons, particularly before 65 years of age. Potential sociocultural factors have not been sufficiently addressed. METHODS: We analyzed data from structured interviews and blood pressure measurements in a population-based sample of 1514 hypertensive (1194 non-Hispanic black and 320 non-Hispanic white) subjects aged 18 to 64 years in Dallas County, Texas, from 2000 to 2002 to identify sociocultural factors associated with low rates of HTN control. We calculated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) using multivariate logistic regression. RESULTS: Awareness, treatment, and control of HTN were negatively associated with a common perception of good health, with aORs (95% CIs) of 0.37 (0.27-0.50) for awareness, 0.47 (0.36-0.62) for treatment, and 0.66 (0.51-0.86) for control. They were positively associated with having a regular physician, with aORs (95% CIs) of 3.81 (2.86-5.07) for awareness, 8.36 (5.95-11.74) for treatment, and 5.23 (3.30-8.29) for control. Among untreated hypertensive subjects, lack of perceived need for a regular physician was associated with perceived good health (aOR [95% CI], 2.2 [1.2-4.0]), male gender (aOR [95% CI], 2.4 [1.4-4.1]), and black race/ethnicity (aOR [95% CI], 2.1 [1.0-4.4]). The HTN outcomes were unrelated to perceived racism or lay beliefs about the causes, consequences, and treatment of HTN. CONCLUSIONS: Among young to middle-aged hypertensive subjects, a perception of good health and the lack of perceived need for a regular physician remain major factors associated with untreated and uncontrolled HTN at the community level-particularly among black men. These factors merit greater emphasis in professional education and public health programs on HTN
