Background: Prior studies have reported a decrease in the proportion of US adults with hypertension that had controlled blood pressure (BP).
Methods: We analyzed data from the National Health and Nutrition Examination Survey (n=25,128, ≥18 years of age) to determine changes in BP control from 2013-2014 to 2021-2023. Hypertension was defined as systolic BP ≥140 mmHg, diastolic BP ≥90 mmHg or antihypertensive medication use.
Background: The association with cardiovascular disease (CVD) is stronger for mean systolic blood pressure (SBP) estimated using ambulatory blood pressure monitoring (ABPM) versus office measurements. Determining whether this is due to ABPM providing more measurement reliability or greater ecological validity can inform its use.
Methods: We estimated the association of mean SBP based on 2 office measurements and 2, 5, 10, and 20 measurements on ABPM with incident CVD in the Jackson Heart Study (n=773).
The purpose of this article is to summarize disparities in blood pressure (BP) by race in the United States, discuss evidence-based strategies to increase equity in BP, review recent American Heart Association BP equity initiatives, and highlight missed opportunities for achieving equity in hypertension. Over 122 million American adults have hypertension, with the highest prevalence among Black Americans. Racial disparities in hypertension and BP control in the United States are estimated to be the single largest contributor to the excess risk for cardiovascular disease among Black versus White adults.

Methods And Results: We analyzed data from 2774 White and 2257 Black US adults from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study taking antihypertensive medication without aTRH at baseline to estimate the association of social determinants of health with incident aTRH. Selection of social determinants of health was guided by the Healthy People 2030 domains of education, economic stability, social context, neighborhood environment, and health care access.
Background: The prevalence of many chronic conditions has increased among US adults. Many adults with hypertension have other chronic conditions.
Methods: We estimated changes in the age-adjusted prevalence of multiple (≥3) chronic conditions, not including hypertension, using data from the National Health and Nutrition Examination Survey, from 1999-2000 to 2017-2020, among US adults with (n = 24,851) and without (n = 24,337 hypertension.
Background: It is unknown whether maintaining normal blood pressure (BP) from middle to older age is associated with improved health outcomes.
Methods: We estimated the proportion of Atherosclerosis Risk in Communities study participants who maintained normal BP from 1987 to 1989 (visit 1) through 1996 to 1998 and 2011 to 2013 (over 4 and 5 visits, respectively). Normal BP was defined as systolic BP <120 mm Hg and diastolic BP <80 mm Hg, without antihypertensive medication.
Background: Death certificate data indicate that hypertension may have increased as a contributing cause of death among US adults. Hypertension is not commonly recorded on death certificates although it contributes to a substantial proportion of cardiovascular disease (CVD) deaths.
Methods: We estimated changes in all-cause, CVD, and non-CVD mortality over 5 years of follow-up among 4 cohorts of US adults with hypertension using mortality follow-up data from National Health and Nutrition Examination Survey III in 1988 to 1994, and National Health and Nutrition Examination Survey cycles from 1999 to 2000 through 2015 to 2016 (n=20 927).
Race differences in ambulatory blood pressure monitoring parameters.
Blood Press Monit
February 2024
Background: Mean systolic and diastolic blood pressure (SBP and DBP) on ambulatory blood pressure (BP) monitoring (ABPM) are higher among Black compared with White adults. With 48 to 72 BP measurements obtained over 24 h, ABPM can generate parameters other than mean BP that are associated with increased risk for cardiovascular events. There are few data on race differences in ABPM parameters other than mean BP.
View Article and Find Full Text PDFBackground: Although blood pressure (BP) increases throughout young adulthood for most individuals, the age-related slope is not uniform. This study aimed to assess associations of demographic, clinical, behavioral, psychosocial, and neighborhood characteristics with age-related BP slope among 4 race-sex groups who participated in the Coronary Artery Risk Development in Young Adults study.
Methods: Individuals (n=3554) aged 18 to 30 years were included in this analysis if they had normal BP at baseline and ≥2 BP measurements during the years 1985/1986 to 2015/2016.
Background: Data from the US National Health and Nutrition Examination Survey are freely available and can be analyzed to produce hypertension statistics for the noninstitutionalized US population. The analysis of these data requires statistical programming expertise and knowledge of National Health and Nutrition Examination Survey methodology.
Methods: We developed a web-based application that provides hypertension statistics for US adults using 10 cycles of National Health and Nutrition Examination Survey data, 1999 to 2000 through 2017 to 2020.
Background: Determining the contribution of social determinants of health (SDOH) to the higher proportion of Black adults with uncontrolled blood pressure (BP) could inform interventions to improve BP control and reduce cardiovascular disease.
Methods: We analyzed data from 7306 White and 7497 Black US adults taking antihypertensive medication from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study (2003-2007). SDOH were defined using the Healthy People 2030 domains of education, economic stability, social context, neighborhood environment, and health care access.
Background: High rates of hypertension and poverty in the rural south contribute to health disparities with Black adults experiencing higher rates of cardiovascular disease than White adults, underscoring the need to identify prevention strategies.
Methods: The equity in prevention and progression of hypertension by addressing barriers to nutrition and physical activity (EPIPHANY) study is a cluster randomized controlled trial testing a multilevel intervention to reduce barriers to a healthy lifestyle to lower blood pressure (BP) among rural, Black adults. Health education fairs offered to 20 churches in the Alabama Black Belt are being used to screen and enroll adults with elevated BP or stage 1 hypertension (systolic BP 120-139 mmHg and diastolic BP < 90 mmHg) who are not recommended for antihypertensive medication, according to the 2017 American College of Cardiology/American Heart Association BP guideline.
Objective: Experiences of child maltreatment are associated with cardiovascular risk and disease in adulthood; however, the mechanisms underlying these associations are poorly understood.
Methods: We examined associations between retrospectively self-reported exposure to child maltreatment (Early Trauma Inventory Self-Report Short Form) and inflammatory responses to mental stress among adults (mean age = 50 years) who recently had a myocardial infarction ( n = 227). Inflammation was assessed as blood interleukin-6 (IL-6), matrix metalloproteinase-9 (MMP-9), and monocyte chemoattractant protein-1 concentrations, measured before and after a standardized public speaking stress task.
Background: Maintaining blood pressure (BP) control over time may contribute to lower risk for cardiovascular disease (CVD) among individuals who are taking antihypertensive medication.
Methods: The Jackson Heart Study (JHS) enrolled 5,306 African-American adults ≥21 years of age and was used to determine the proportion of African Americans that maintain persistent BP control, identify factors associated with persistent BP control, and determine the association of persistent BP control with CVD events. This analysis included 1,604 participants who were taking antihypertensive medication at Visit 1 and had BP data at Visits 1 (2000-2004), 2 (2005-2008), and 3 (2009-2013).
Objectives: Examine childhood obesity incidence across recent cohorts.
Methods: We examined obesity incidence and prevalence across 2 cohorts of children in the United States 12 years apart using the Early Childhood Longitudinal Studies, parallel data sets following the kindergarten cohorts of 1998 and 2010 with direct anthropometric measurements at multiple time points through fifth grade in 2004 and 2016, respectively. We investigated annualized incidence rate and cumulative incidence proportion of obesity (BMI z-score ≥95th percentile based on Centers for Disease Control and Prevention weight-for-age z-scores).
Introduction: For many people, blood pressure (BP) levels differ when measured in a medical office versus outside of the office setting. Out-of-office BP has a stronger association with cardiovascular disease (CVD) events compared with BP measured in the office. Many BP guidelines recommend measuring BP outside of the office to confirm the levels obtained in the office.
View Article and Find Full Text PDFBackground: The National Health and Nutrition Examination Survey data indicate that the proportion of US adults with hypertension that had controlled blood pressure (BP) declined from 2013 to 2014 through 2017 to 2018. We analyzed data from National Health and Nutrition Examination Survey 2009 to 2012, 2013 to 2016, and 2017 to 2020 to confirm this finding.
Methods: Hypertension was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg or antihypertensive medication use.
The authors examined the proportion of US adults that would have their high blood pressure (BP) status changed if systolic BP (SBP) and diastolic BP (DBP) were measured with systematic bias and/or random error versus following a standardized protocol. Data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES; n = 5176) were analyzed. BP was measured up to three times using a mercury sphygmomanometer by a trained physician following a standardized protocol and averaged.

Higher BMI is associated with an increased risk for hypertension but the association between BMI and BP control is not well characterized. We examined hypertension awareness, antihypertensive medication use, and BP control, by BMI category.
View Article and Find Full Text PDFPurpose: This paper determined sodium provisions from a seven-day cycle menu and commissary at a rural Southwest County jail and compared it to Dietary Reference Intakes (DRI) and Dietary Approaches to Stop Hypertension (DASH) recommendations for sodium.
Design/methodology/approach: A seven-day cycle menu and commissary items were used to determine sodium content for each meal and commissary pack. Estimates for the menu and commissary packs paired with the menu (commissary scenarios) were converted to a daily average of sodium and compared to DRI and DASH recommendations.
Background: The mean systolic blood pressure (SBP) for US adults increases with age. Determining characteristics of US adults ≥65 years with normal blood pressure (BP) may inform approaches to prevent this increase.
Methods: We analyzed US National Health and Nutrition Examination Survey 2011-2018 data (n = 21,581).
Background: Not having a healthcare visit in the past year has been associated with a higher likelihood of uncontrolled blood pressure (BP) among individuals with hypertension.
Methods: We examined factors associated with not having a healthcare visit in the past year among US adults with hypertension using data from the US National Health and Nutrition Examination Survey 2013-2018 (n = 5,985). Hypertension was defined as systolic BP (SBP) ≥140 mm Hg, diastolic BP (DBP) ≥90 mm Hg, or antihypertensive medication use.
Background: The 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline recommends using 10-year predicted atherosclerotic cardiovascular disease (ASCVD) risk to guide decisions to initiate antihypertensive medication.
Methods: We included adults aged 40-79 years from the National Health and Nutrition Examination Survey 2013-2018 (n = 8803). We computed 10-year predicted ASCVD risk using the Pooled Cohort risk equations.
