Abstract
Community-based participatory research (CBPR) using barbershop interventions is an emerging approach to address health disparities and promote health equity. Barbershops serve as trusted community settings for health education, screening services, and referrals. This narrative mini-review provides an overview of the current state of knowledge regarding CBPR employing barbershop interventions and explores the potential for big data involvement to enhance the impact and reach of this approach in combating chronic disease. CBPR using barbershop interventions has shown promising results in reducing blood pressure among Black men and improving diabetes awareness and self-management. By increasing testing rates and promoting preventive behaviors, barbershop interventions have been successful in addressing infectious diseases, including HIV and COVID-19. Barbershops have also played roles in promoting cancer screening and increasing awareness of cancer risks, namely prostate cancer and colorectal cancer. Further, leveraging the trusted relationships between barbers and their clients, mental health promotion and prevention efforts have been successful in barbershops. The potential for big data involvement in barbershop interventions for chronic disease management offers new opportunities for targeted programs, real-time monitoring, and personalized approaches. However, ethical considerations regarding privacy, confidentiality, and data ownership need to be carefully addressed. To maximize the impact of barbershop interventions, challenges such as training and resource provision for barbers, cultural appropriateness of interventions, sustainability, and scalability must be addressed. Further research is needed to evaluate long-term impact, cost-effectiveness, and best practices for implementation. Overall, barbershops have the potential to serve as key partners in addressing chronic health disparities and promoting health equity.

[PMID: 38552194 PMCID: PMC11088430 DOI: 10.1111/jch.14804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 02/28/2024] [Accepted: 03/08/2024] [Indexed: 05/12/2024]
Abstract
The aims of our study were to examine whether initial or subsequent adiposity status had a greater effect on hypertension. We collected data in 1992 and again in 2007 from the same group of 597 individuals in the middle age. The subjects were classified into four groups: individuals with a normal body mass index (BMI) in 1992 and 2007 were in Group I; those with a normal BMI in 1992, but became overweight or obese in 2007 were in Group II; those who were overweight or obese in 1992, but had a normal BMI in 2007 were in Group III; and those who were overweight or obese in 1992 and 2007 were in Group IV. Their demographic data were recorded. The relationship between adiposity status and hypertension was analyzed using logistic regression model. The cumulative incidence of hypertension was 35.5%, 56.3%, 50.0%, and 65.1% for Group I to IV, respectively. Compared with Group I, after adjusted factors, the hazard ratio (HR) was 1.80 for Group II (P = .001), 1.40 for Group III (P = .150), and 2.31 for Group IV (P < .001). Adiposity status in 2007 could predict hypertension (OR = 2.5, P < .001), as opposed to the initial adiposity status (P = .148). Subsequently adiposity status could have major effects on hypertension. Our society is very short of public health resources, particularly in developing countries, we should pay more attention to current adiposity status and encourage middle-aged people to lose weight.

Abstract
Hypertension is a leading cause of mortality globally and one of the most common risk factors for cardiovascular disease. Diagnosis, awareness, and optimal treatment rates are suboptimal, especially in low- and middle-income countries, with attendant high health consequences and grave socioeconomic impact. There is an enormous gap between disease burden and physician-patient ratios that needs to be bridged. Task sharing and task shifting (TSTS) provide a viable temporary solution. However, sociocultural, demographic, and economic factors influence the effective uptake of such interventions. This review discusses the dynamics of TSTS in the African context looking at challenges, feasibility, and approach to adopt it in the management of hypertension in Africa.

Abstract
BACKGROUND Variation in blood pressure levels display circadian rhythms. Complete 24-hour blood pressure control is the primary goal of antihypertensive treatment and reducing adverse cardiovascular outcomes is the ultimate aim. This is an update of the review first published in 2011. OBJECTIVES To evaluate the effectiveness of administration-time-related effects of once-daily evening versus conventional morning dosing antihypertensive drug therapy regimens on all-cause mortality, cardiovascular mortality and morbidity, total adverse events, withdrawals from treatment due to adverse effects, and reduction of systolic and diastolic blood pressure in people with primary hypertension. SEARCH METHODS We searched the Cochrane Hypertension Specialised Register via Cochrane Register of Studies (17 June 2022), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 6, 2022); MEDLINE, MEDLINE In-Process and MEDLINE Epub Ahead of Print (1 June 2022); Embase (1 June 2022); ClinicalTrials.gov (2 June 2022); Chinese Biomedical Literature Database (CBLD) (1978 to 2009); Chinese VIP (2009 to 7 August 2022); Chinese WANFANG DATA (2009 to 4 August 2022); China Academic Journal Network Publishing Database (CAJD) (2009 to 6 August 2022); Epistemonikos (3 September 2022) and the reference lists of relevant articles. We applied no language restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing the administration-time-related effects of evening with morning dosing monotherapy regimens in people with primary hypertension. We excluded people with known secondary hypertension, shift workers or people with white coat hypertension. DATA COLLECTION AND ANALYSIS Two to four review authors independently extracted data and assessed trial quality. We resolved disagreements by discussion or with another review author. We performed data synthesis and analyses using Review Manager Web for all-cause mortality, cardiovascular mortality and morbidity, serious adverse events, overall adverse events, withdrawals due to adverse events, change in 24-hour blood pressure and change in morning blood pressure. We assessed the certainty of the evidence using GRADE. We conducted random-effects meta-analysis, fixed-effect meta-analysis, subgroup analysis and sensitivity analysis. MAIN RESULTS We included 27 RCTs in this updated review, of which two RCTs were excluded from the meta-analyses for lack of data and number of groups not reported. The quantitative analysis included 25 RCTs with 3016 participants with primary hypertension. RCTs used angiotensin-converting enzyme inhibitors (six trials), calcium channel blockers (nine trials), angiotensin II receptor blockers (seven trials), diuretics (two trials), α-blockers (one trial), and β-blockers (one trial). Fifteen trials were parallel designed, and 10 trials were cross-over designed. Most participants were white, and only two RCTs were conducted in Asia (China) and one in Africa (South Africa). All trials excluded people with risk factors of myocardial infarction and strokes. Most trials had high risk or unclear risk of bias in at least two of several key criteria, which was most prominent in allocation concealment (selection bias) and selective reporting (reporting bias). Meta-analysis showed significant heterogeneity across trials. No RCTs reported on cardiovascular mortality and cardiovascular morbidity. There may be little to no differences in all-cause mortality (after 26 weeks of active treatment: RR 0.49, 95% CI 0.04 to 5.42; RD 0, 95% CI -0.01 to 0.01; very low-certainty evidence), serious adverse events (after 8 to 26 weeks of active treatment: RR 1.17, 95% CI 0.53 to 2.57; RD 0, 95% CI -0.02 to 0.03; very low-certainty evidence), overall adverse events (after 6 to 26 weeks of active treatment: RR 0.89, 95% CI 0.67 to 1.20; I² = 37%; RD -0.02, 95% CI -0.07 to 0.02; I² = 38%; very low-certainty evidence) and withdrawals due to adverse events (after 6 to 26 weeks active treatment: RR 0.76, 95% CI 0.47 to 1.23; I² = 0%; RD -0.01, 95% CI -0.03 to 0; I² = 0%; very low-certainty evidence), but the evidence was very uncertain. AUTHORS' CONCLUSIONS Due to the very limited data and the defects of the trials' designs, this systematic review did not find adequate evidence to determine which time dosing drug therapy regimen has more beneficial effects on cardiovascular outcomes or adverse events. We have very little confidence in the evidence showing that evening dosing of antihypertensive drugs is no more or less effective than morning administration to lower 24-hour blood pressure. The conclusions should not be assumed to apply to people receiving multiple antihypertensive drug regimens.

Abstract
Hypertension is the predominant risk factor for cardiovascular disease related morbidity and mortality among Black adults in the United States. It contributes significantly to the development of heart failure and increases the risk of death following heart failure diagnosis. It is also a leading predisposing factor for hypertensive disorders of pregnancy and peripartum cardiomyopathy in Black women. As such, all stakeholders including health care providers, particularly primary care clinicians (including physicians and advanced practice providers), patients, and communities must be aware of the consequences of uncontrolled hypertension among Black adults. Appropriate treatment strategies should be identified and implemented to ensure timely and effective blood pressure management among Black individuals, particularly those with, and at risk for heart failure.

Abstract
BACKGROUND This study aimed to investigate the proportion of prehypertension cases progressing to hypertension among Chinese middle-aged and elderly populations over a 2-year period and related influencing factors. METHODS Data were obtained from the China Health and Retirement Longitudinal Study, and 2,845 individuals who were ≥ 45 years old and prehypertensive at baseline were followed from 2013-2015. Structured questionnaires were administered, and blood pressure (BP) and anthropometric measurements were performed by trained personnel. Multiple logistic regression analysis was done to investigate factors associated with prehypertension progressing to hypertension. RESULTS Over the 2-year follow-up, 28.5% experienced progression of prehypertension to hypertension; this occurred more frequently in men than women (29.7% vs. 27.1%). Among men, older age (55-64 years: adjusted odds ratio [aOR] = 1.414, 95% confidence interval [CI]:1.032-1.938; 65-74 years: aOR = 1.633, 95%CI: 1.132-2.355; ≥ 75 years: aOR = 2.974, 95%CI: 1.748-5.060), obesity (aOR = 1.634, 95%CI: 1.022-2.611), and number of chronic diseases (1: aOR = 1.366, 95%CI: 1.004-1.859; ≥ 2: aOR = 1.568, 95%CI: 1.134-2.169) were risk factors for progression to hypertension whereas being married/cohabiting (aOR = 0.642, 95% CI: 0.418-0.985) was a protective factor. Among women, risk factors included older age (55-64 years: aOR = 1.755, 95%CI: 1.256-2.450; 65-74 years: aOR = 2.430, 95%CI: 1.605-3.678; ≥ 75 years: aOR = 2.037, 95% CI: 1.038-3.995), married/cohabiting (aOR = 1.662, 95%CI: 1.052-2.626), obesity (aOR = 1.874, 95%CI: 1.229-2.857), and longer naps (≥ 30 and < 60 min: aOR = 1.682, 95%CI: 1.072-2.637; ≥ 60 min: aOR = 1.387, 95%CI: 1.019-1.889). CONCLUSIONS Chinese middle-aged and elderly individuals experienced a risk of prehypertension progressing to hypertension over a 2-year period, although the influencing factors differed by sex; this should be considered in interventions.

Associations between TyG-BMI and normal-high blood pressure values and hypertension: cross-sectional evidence from a non-diabetic population. Front Cardiovasc Med 2023; 10:1129112. [PMID: 37168658 PMCID: PMC10164981 DOI: 10.3389/fcvm.2023.1129112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 04/11/2023] [Indexed: 05/13/2023] Open
Abstract
Objective Triglyceride glucose body mass index (TyG-BMI) has been shown to be strongly associated with a variety of chronic diseases. However, little is known about the associations between TyG-BMI and normal-high blood pressure (BP) values and hypertension (HTN). Method The current study was cross-sectional in design and included 15,464 non-diabetic participants recruited between 1994 and 2016 in the NAGALA (NAfld in the Gifu Area, Longitudinal Analysis) study. Associations between TyG-BMI and normal-high BP values and HTN were assessed using multivariate logistic regression. The ability of the TyG index, BMI, and their combined index TyG-BMI to identify normal-high BP values and HTN was compared by receiver operating characteristic (ROC) curves. Results Among the 15,464 eligible non-diabetic participants, 28.56% (4,416/15,464) and 6.23% (964/15,464) had normal-high BP values and HTN, respectively. Multivariate logistic regression analysis showed positive correlations between BMI, TyG index, TyG-BMI and normal-high BP values/HTN; after standardized regression coefficients, TyG-BMI had the strongest association with normal-high BP values and HTN compared to BMI and TyG index. In the fully adjusted model, the odds ratio (OR) value corresponding to the relationship between TyG-BMI and HTN/normal-high BP values was 2.35; when TyG-BMI was used as a categorical variable, compared with the lowest quartile of TyG-BMI the regression coefficient for the association of the highest quartile of TyG-BMI with normal-high BP values increased by 426%, while the regression coefficient for the association with HTN increased by 527%. In further spline regression analysis, we also found that there was a linearly positive correlation between TyG-BMI and systolic BP/diastolic BP (SBP/DBP), which supported the linear trend between TyG-BMI and HTN/normal-high BP values (P-trend <0.0001). In addition, ROC analysis showed that TyG-BMI had good diagnostic values for both normal-high BP values and HTN, and TyG index combined with BMI can significantly improve the ability of a single index to identify normal-high BP values and HTN. Conclusion In the non-diabetic population, TyG-BMI showed a significant positive correlation with both normal-high BP values and HTN, and TyG-BMI was of higher value for the identification of both normal-high BP values and HTN compared to BMI and TyG index alone.

Abstract
Prehypertension is a clinical condition that increases the risk of hypertension and cardiovascular disease. In South American countries, prehypertension affects almost one-third of the population. The aim of the present study was to determine the association between prehypertension and the main cardiometabolic risk factors according to the US National Cholesterol Education Program Adult Treatment Panel III by sex in the Peruvian population. A total of 863 participants surveyed were included in the study. A total of 21.1% had prehypertension, 14.4% of whom were female, and 30.5% were male. Women belonging to the age group 50–59 years, having abdominal obesity and being a current smoker, were more likely to have prehypertension, while the likelihood of having prehypertension increased in men with abdominal obesity. Three out of 10 men and one out of 10 women in Peru have prehypertension. In women, being 50 to 59 years of age, having abdominal obesity, and being a current smoker, increased the probability of having prehypertension, whereas, in men, only abdominal obesity was found to be associated with prehypertension. Our findings will allow the development of prevention strategies focused on the appropriate diagnosis of prehypertension and cardiometabolic risk factors according to sex.

Zhang X, Yu C, Ye R, Liu T, Chen X. Correlation between non-insulin-based insulin resistance indexes and the risk of prehypertension: A cross-sectional study. J Clin Hypertens (Greenwich) 2022; 24:573-581. [PMID: 35411676 PMCID: PMC9106071 DOI: 10.1111/jch.14449] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 02/01/2022] [Accepted: 02/06/2022] [Indexed: 02/05/2023]
Abstract
The authors aimed to characterize the relationships between non-insulin-based insulin resistance (IR) indexes and the risk of prehypertension, and to compare their abilities to identify prehypertension. The authors recruited 3274 adults who did not have hypertension and were not taking hypoglycemic or lipid-lowering medications. The triglyceride-to-high-density lipoprotein-cholesterol ratio (TG/HDL-C), fasting triglyceride and glucose index (TyG), and metabolic score for IR (METS-IR) were calculated. Bivariate Spearman's correlation analysis and multiple logistic analysis were used. The area under the receiver operating characteristic (ROC) curve was used to compare the ability of the three indexes to identify prehypertension. Systolic and diastolic blood pressure (BP) positively correlated with TG/HDL-C (r = .272, P < .001), TyG (r = .286, P < .001), and METS-IR (r = .340, P < .001) in the entire cohort. Multiple logistic analysis showed that the proportion of prehypertension in the third and fourth quartiles of the TG/HDL-C (Q3 vs. Q1: odds ratio (OR) = 1.527, 95% confidence interval (CI): 1.243-1.988; Q4 vs. Q1: OR = 1.580, 95% CI: 1.231-2.028), TyG (Q3 vs. Q1: OR = 1.519, 95% CI: 1.201-1.923; Q4 vs. Q1: OR = 1.658, 95% CI: 1.312-2.614), and METS-IR (Q3 vs. Q1: OR = 1.542, 95% CI: 1.138-2.090; Q4 vs. Q1:OR = 2.216, 95% CI: 1.474-3.331) were significantly higher than in the lowest quartiles. The areas under the curves and 95% CIs for the identification of prehypertension were .647 (.628-.667) for TG/HDL-C, .650 (.631-.669) for TyG, and .683 (.664-.702) for METS-IR, respectively. Thus, non-insulin-based IR indexes (TG/HDL-C, TyG, and METS-IR) are significantly associated with the risk of prehypertension. Furthermore, METS-IR is better able to identify prehypertension than TG/HDL-C and TyG. These non-insulin-based IR indexes might assist with the prevention of hypertension in primary care and areas with limited medical resources.

Abstract
BACKGROUND Hypertension is a highly prevalent condition in the general population, conferring a high risk of significant morbidity and mortality. Associated with the condition are many well-characterized controllable and noncontrollable risk factors. This study aimed to identify the prevalence of hypertension in the outpatient podiatric medical clinic setting and to determine the relevance of hypertension risk factors in this setting. METHODS A survey tool was created to characterize relevant risk factors, and systolic and diastolic blood pressures were recorded. Descriptive statistics were generated after conclusion of enrollment. Analysis was also performed to determine the relationship between individual risk factors and systolic blood pressure. RESULTS Of the 176 patients, 56 (31.8%) had an incidentally high blood pressure at intake, including 18.5% of patients without a known history of hypertension and 38.5% with a known history of hypertension. Three risk factors were found to be significantly associated with increasing systolic blood pressure: weight (P = .022), stress level (P = .017), and presence of renal artery stenosis (P = .021). There was also a near-statistically significant inverse relationship between systolic blood pressure and amount of time spent exercising (P = .068). CONCLUSIONS Overall, a relatively high prevalence of incidental hypertension was identified, including among patients not previously diagnosed as having hypertension. Consideration of risk factors and awareness of the prevalence of the condition can be useful for practitioners, even as they manage presenting podiatric medical concerns. Future investigations may consider interventional or preventive strategies in the outpatient clinic setting.

Abstract
This review article is focused on antihypertensive drugs, namely angiotensin converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB), and their immunomodulatory properties reported in hypertensive patients as well as in experimental settings involving studies on animal models and cell lines. The immune regulatory action of ACEI and ARB is mainly connected with the inhibition of proinflammatory cytokine secretion, diminished expression of adhesion molecules, and normalization of CRP concentration in the blood plasma. The topic has significant importance in future medical practice in the therapy of patients with comorbidities with underlying chronic inflammatory responses. Thus, this additional effect of immune regulatory action of ACEI and ARB may also benefit the treatment of patients with metabolic syndrome, allergies, or autoimmune disorders.

Abstract
BACKGROUND AND AIMS Low serum potassium concentration is associated with hypertension, but whether the same association can be found in African origin populations, is unknown. We assessed serum potassium concentration, and its association with hypertension among Ghanaians living in different geographical locations. METHODS Baseline data of 962 rural, 1420 urban, and 2947 migrant Ghanaians from the Research on Obesity and Diabetes among African Migrants study were analysed. Mean serum potassium concentration was compared between the groups, and the association between serum potassium and hypertension was assessed using multivariate regression analyses. RESULTS Mean serum potassium concentration was higher in rural Ghana (4.28, 95% confidence interval 4.25-4.32 mmol/L) than in Ghanaians living in Amsterdam (3.90, 3.88-3.92 mmol/L) and London (4.11, 4.07-4.14 mmol/L), but lower than in Ghanaians living in urban Ghana (4.38, 4.34-4.42 mmol/L) and Berlin (4.57, 4.51-4.62 mmol/L) in both sexes. In the age-adjusted analyses, serum potassium was associated with hypertension in urban- (odds ratio 0.44, 0.23-0.82), London- (0.34, 0.17-0.64) and Amsterdam-Ghanaian males (0.41, 0.20-0.86), and in rural- (0.49, 0.28-0.84), London- (0.29, 0.17-0.49) and Amsterdam-Ghanaian females (0.33, 0.17-0.64). However, after adjustment for demographic, lifestyle, and health factors, serum potassium was associated with hypertension in Amsterdam-Ghanaian males only (0.12, 0.02-0.59). CONCLUSIONS This study shows differences in mean serum potassium among Ghanaian populations living in different locations in Europe and Ghana, and different associations with hypertension between sites. Further research should focus on elucidating the mechanism underlying potassium handling and blood pressure regulation in African populations, in order to mitigate the burden of hypertension among these populations.

Abstract
Background There are indications that prehypertension precedes hypertension. Like hypertension, it is associated with increased cardiovascular risk. Objective To determine the prevalence, awareness and correlates of prehypertension and hypertension among adults in Delta State, Nigeria. Methods This was a cross-sectional study. We recruited adults aged ≥18 years from two communities in Delta State, Nigeria, using the multi-stage sampling technique. The study instrument was a modified WHO-STEPS questionnaire. Prehypertension and hypertension were defined using the JNC-7 criteria. Ethical approval was obtained before the recruitment of participants. Results Of the 852 adults studied, the mean (±SD) age was 42.64 (±16.07) years, females (55.9%) and urban dwellers (55.8%). The prevalence of prehypertension and hypertension were 42.5% and 29.3%, respectively; both were higher among urban dwellers. The peak age-group for prehypertension and hypertension were 25-34 and 35-44 years, respectively. Awareness of hypertension was low; 12.0% (102/852). Blood pressure category significantly correlated with age, body mass index, place of residence, level of education, employment status and fruit intake. Conclusion The prevalence of prehypertension and hypertension in this study were high. Based on the premise that prehypertension is a precursor of hypertension and occurred more among youths, the higher prevalence of prehypertension gives an inkling to rising prevalence of hypertension.

Abstract
Evidence is lacking about the role of serum uric acid (SUA) in the progression from prehypertension to hypertension. Herein, we aimed to investigate the association of both baseline and dynamic change in SUA with the risk of hypertension developing from prehypertension. The study enrolled 11,488 participants with prehypertension during 2006-2010 from the Kailuan study. Change in SUA was assessed as % change of SUA from 2006 (baseline) to 2010. Participants were categorized into four groups by quartiles of baseline and change in SUA, separately. Multivariable logistic regressions were used to calculation the odds ratio (OR) and 95% confidence interval (CI). During a median follow-up of 7.06 years, 2716 (23.64%) participants developed hypertension from prehypertension. In the multivariable-adjusted model, the OR for hypertension comparing participants in the highest versus the lowest quartile of baseline SUA were 1.18 (95% CI, 1.02-1.36). Increased SUA over time was also associated with elevated risk of hypertension (OR in the highest quartile was 1.41 [95% CI, 1.23-1.62] versus the lowest quartile), especially in those with baseline SUA ≥ median (OR, 1.48; 95% CI, 1.21-1.81). Moreover, the addition of SUA to a conventional risk model had an incremental effect on the predictive value for hypertension (integrated discrimination improvement 0.30%, P < 0.0001; category-free net reclassification improvement 12.36%, P < 0.0001). Both high initial SUA and increased SUA over time can independently predict the progression from prehypertension to hypertension. Strategies aiming at controlling SUA level in prehypertensive subjects may impede the onset of hypertension.

Abstract
In 1939, Robinson and Brucer first proposed the concept of prehypertension (PHTN), which was defined as a systolic blood pressure of 120–139 mmHg and/or diastolic blood pressure of 80–89 mmHg. PHTN is a major global health risk that adversely affects human health, especially the cardiovascular system. People with PHTN have a higher risk of developing cardiovascular diseases, including stroke, coronary heart disease, myocardial infarction and total cardiovascular events. However, there are few systematic summaries of the relationship between PHTN and the cardiovascular system. Furthermore, because the definition of ‘normal BP’ and the advantages of more intensive BP control remain unclear, there is no consensus on optimal interventions. In an attempt to provide information for clinicians or professionals who are interested in reducing the risk associated with PHTN, we review the existing studies to provide references for them with the effects of PHTN on the cardiovascular system and the potential pathogenic mechanisms of PHTN, including inflammatory responses, insulin resistance, endothelial dysfunction, sympathovagal imbalance, activation of the renin-angiotensin system and others. PHTN is highly prevalent and has adverse effects on health. An effective public health strategy is important to prevent the progression of PHTN. We envisage that this information will increase the public attention of PHTN and help to provide more strategies to reduce the risk of cardiovascular events.

Abstract
Background The role of inflammation in the development of hypertension remains incompletely understood. While single inflammatory mediators have been shown to associate with changes in blood pressure (ΔBP), the role of clusters of inflammatory mediators has been less comprehensively explored. We therefore determined whether individual or clusters of inflammatory mediators from a large biomarker panel were associated with ΔBP over 4.5 years, in young healthy adults. Methods We included 358 adults (white, n = 156; black, n = 202) with detailed information on ambulatory blood pressure (BP) at baseline and follow-up. Baseline blood samples were analysed for 22 inflammatory mediators using multiplexing technology. Principal component analysis was used to study associations between clusters of inflammatory mediators and ΔBP. Results In the total cohort in multivariable-adjusted regression analyses, percentage change in 24hr systolic BP associated positively with Factors 1 (Interferon-gamma, interleukin (IL)-4, IL-7, IL-10, IL-12, IL-17A, IL-21, IL-23, macrophage inflammatory protein (MIP)-1α, MIP-1β, TNF-α, granulocyte-macrophage colony-stimulating factor (GM-CSF)) and 2 (IL-5, IL-6, IL-8, IL-13). Change in daytime systolic BP associated positively with Factors 1, 2 and 3 (C-Reactive protein, IL-1β, IL-2, MIP-3α). Subgroup analysis found these findings were limited to white study participants. Numerous associations were present between individual inflammatory mediators (Interferon-gamma, GM-CSF, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17A, IL-21, IL-23, MIP-1α and MIP-1β) and ΔBP in the white but not black subgroups. Conclusion We found independent relationships between numerous inflammatory mediators (individual and clusters) and ΔBP over 4.5 years. The relationship between inflammatory markers and ΔBP was only found in white participants. ClinicalTrials.gov (Identifier: NCT03292094)..

Abstract
We tested the hypothesis that inducible nitric oxide synthase (iNOS) contributes to reduced nitric oxide (NO)-dependent vasodilation in non-Hispanic Blacks and prehypertensive non-Hispanic Whites. Twenty Black and twenty White participants (10 normotensive, 10 prehypertensive per group; n = 40 total) participated in this study. Participants were instrumented with two microdialysis fibers, and each site was randomized as control (lactated Ringer) or iNOS inhibition (0.1 mM 1400W). Laser-Doppler flow probes and local heaters were used to measure skin blood flow and heat the skin to induce vasodilation, respectively. Each site was heated from 33°C to 39°C (rate: 0.1°C/s). Once a plateau was established, 20 mM nitro-l-arginine methyl ester (l-NAME), a nonspecific NOS inhibitor, was infused at each site to quantify NO-dependent vasodilation. At control sites, %NO-dependent vasodilation was reduced in prehypertensive Whites (47 ± 10%NO) and in both normotensive and prehypertensive Blacks (39 ± 9%NO and 28 ± 5%NO, respectively) relative to normotensive Whites (73 ± 8%NO; P < 0.0001 for all comparisons). Compared with respective control sites, iNOS inhibition increased NO-dependent vasodilation in prehypertensive Whites (68 ± 8%NO) and in both normotensive and prehypertensive Blacks (78 ± 8%NO and 55 ± 6%NO, respectively; P < 0.0001 for all comparisons). We failed to find an effect for normotensive Whites (77 ± 7%NO). After iNOS inhibition, %NO-dependent vasodilation was similar between normotensive Whites, prehypertensive Whites, and normotensive Blacks. Inhibition of iNOS increased NO-dependent vasodilation to a lesser extent in prehypertensive Blacks. These data suggest that iNOS contributes to reduced NO-dependent vasodilation in prehypertension and in Black participants.NEW & NOTEWORTHY Inducible nitric oxide synthase (iNOS) is typically upregulated in conditions of increased oxidative stress and may have detrimental effects on the vasculature. Endothelial nitric oxide (NO), which is cardioprotective, is reduced in prehypertensive non-Hispanic Whites and in non-Hispanic Blacks. We found that inhibition of iNOS can increase endothelial NO-dependent vasodilation in prehypertensive White participants and in both normotensive and prehypertensive Black participants.Inducible nitric oxide (NO) synthase (iNOS) can be upregulated under conditions of increased oxidative stress and may have detrimental effects on the vasculature.

Abstract
Background Life's Simple 7 (LS7; nutrition, physical activity, cigarette use, body mass index, blood pressure, cholesterol, glucose) predicts cardiovascular health. The principal objective of our study was to define demographic and socioeconomic factors associated with LS7 to better inform programs addressing cardiovascular health and health equity. Methods National Health and Nutrition Examination Surveys 1999-2016 data were analyzed on non-Hispanic White [NHW], NH Black [NHB], and Hispanic adults aged ≥20 years without cardiovascular disease. Each LS7 variable was assigned 0, 1, or 2 points for poor, intermediate, and ideal levels, respectively. Composite LS7 scores were grouped as poor (0-4 points), intermediate (5-9), and ideal (10-14). Results 32,803 adults were included. Mean composite LS7 scores were below ideal across race/ethnicity groups. After adjusting for confounders, NHBs were less likely to have optimal LS7 scores than NHW (multivariable odds ratios (OR .44; 95% CI .37-.53), whereas Hispanics tended to have better scores (1.18; .96-1.44). Hispanics had more ideal LS7 scores than NHBs, although Hispanics had lower incomes and less education, which were independently associated with fewer ideal LS7 scores. Adults aged ≥45 years were less likely to have ideal LS7 scores (.11; .09-.12) than adults aged <45 years. Conclusions NHBs were the least likely to have optimal scores, despite higher incomes and more education than Hispanics, consistent with structural racism and Hispanic paradox. Programs to optimize lifestyle should begin in childhood to mitigate precipitous age-related declines in LS7 scores, especially in at-risk groups. Promoting higher education and reducing poverty are also important.

Abstract
The purpose of this study was to investigate the effect of race and subclinical elevations in blood pressure (i.e., prehypertension) on cutaneous sensory nerve-mediated and nitric oxide (NO)-dependent vasodilation. We recruited participants who self-identified as either non-Hispanic black (n = 16) or non-Hispanic white (n = 16). Within each group, participants were subdivided as either normotensive (n = 8 per group) or prehypertensive (n = 8 per group). Each participant was instrumented with four intradermal microdialysis fibers: 1) control (lactated Ringer's), 2) 5% lidocaine (sensory nerve inhibition), 3) 20 mM Nω-nitro-l-arginine methyl ester (l-NAME) (NO synthase inhibition), and 4) lidocaine + l-NAME. Skin blood flow was assessed via laser-Doppler flowmetry, and each site underwent local heating from 33°C to 39°C. At the plateau, 20 mM l-NAME were infused at control and lidocaine sites to quantify NO-dependent vasodilation. Maximal vasodilation was induced via 54 mM sodium nitroprusside and local heating to 43°C. Data are means ± SD. Sensory nerve-mediated cutaneous vasodilation was reduced in prehypertensive non-Hispanic white (34 ± 7%) and both non-Hispanic black groups (normotensive, 20 ± 9%, prehypertensive, 24 ± 15%) relative to normotensive non-Hispanic whites (54 ± 12%). NO-dependent vasodilation was also reduced in prehypertensive non-Hispanic white (41 ± 7%) and both non-Hispanic black groups (normotensive, 44 ± 7%, prehypertensive, 19 ± 7%) relative to normotensive non-Hispanic whites (60 ± 11%). The decrease in NO-dependent vasodilation in prehypertensive non-Hispanic blacks was further reduced relative to all other groups. These data suggest subclinical increases in blood pressure adversely affect sensory-mediated and NO-dependent vasodilation in both non-Hispanic blacks and whites.NEW & NOTEWORTHY Overt hypertension is known to reduce cutaneous sensory nerve-mediated and nitric oxide (NO)-dependent vasodilation, but the effect of subclinical increases in blood pressure (i.e., prehypertension) is unknown. The combined effect of race and prehypertension is also unknown. In this study, we found that prehypertension reduces cutaneous sensory nerve-mediated and NO-dependent vasodilation in both non-Hispanic white and black populations, with the greatest reductions observed in prehypertensive non-Hispanic blacks.

Abstract
Relative to non-Hispanic Whites, non-Hispanic Blacks are disproportionately affected by elevated blood pressure (BP). It is unknown whether race or subclinical increases in BP affect the ability of cutaneous sensory nerves to induce cutaneous microvascular vasodilation. Sixteen participants who self-identified as non-Hispanic Black (n = 8) or non-Hispanic White (n = 8) were subgrouped as normotensive or prehypertensive. Participants were instrumented with three intradermal microdialysis fibers: (a) control, (b) 1 μM sodium nitroprusside (SNP), an exogenous nitric oxide (NO) donor, and (c) 20 mM NG -nitro-l-arginine methyl ester (L-NAME), a non-selective NO synthase inhibitor. A slow local heating protocol (33-40°C, 0.1°C/min) was used to assess the onset of cutaneous sensory nerve-mediated vasodilation (temperature threshold) and skin blood flow was measured using laser-Doppler flowmetry. At control sites, the temperature threshold occurred at a higher temperature in non-Hispanic Blacks (normotensive: 37.2 ± 0.6°C, prehypertensive: 38.9 ± 0.5°C) compared to non-Hispanic Whites (normotensive: 35.2 ± 0.8°C, prehypertensive: 35.2 ± 0.9°C). L-NAME shifted the temperature threshold higher in non-Hispanic Whites (normotensive: 37.8 ± 0.7°C, prehypertensive: 38.2 ± 0.8°C), but there was no observed effect in non-Hispanic Blacks. SNP did not affect temperature threshold in non-Hispanic Whites, but shifted the temperature threshold lower in non-Hispanic Blacks (normotensive: 34.6 ± 1.2°C, prehypertensive: 34.8 ± 1.1°C). SNP mitigated differences in temperature threshold across all groups. There was no effect found for BP status in either the non-Hispanic Black or non-Hispanic White groups. These data suggest that reduced NO bioavailability affects the ability of cutaneous sensory nerves to induce microvascular vasodilation in young, otherwise healthy non-Hispanic Blacks.

Abstract
The incidence of prehypertension (blood pressure 120-139 and/or 80-89 mm Hg) in young adults worldwide ranges from ~37.5% to 77.1%. Identifying high-risk groups of prehypertension in young adults is helpful for early and effective interventions and treatments to reduce the occurrence of future hypertension and organ damage. This review summarized the epidemiological characteristics, disease intervention measures, and disease progression characteristics of prehypertension to provide a basis for the development of targeted intervention measures for young adults with prehypertension.

Abstract
Compared with whites, blacks develop hypertension earlier in life, progress from prehypertension to hypertension at an accelerated rate, and exhibit greater hypertension-mediated organ damage (e.g., kidney disease, stroke). In this paper, we tested whether the longitudinal associations between elevated systolic blood pressure and disruption of brain white matter structural integrity differ as a function of race. A community sample of 100 middle-aged adults with prehypertension underwent diffusion imaging to quantify indirect metrics of white matter structural integrity, including fractional anisotropy. Blood pressure and diffusion imaging measurements were collected at baseline and at a 2-year follow-up. Regression analyses showed that higher systolic blood pressure at baseline was associated with a decrease in fractional anisotropy over 2 years in blacks only (β = -0.51 [95% CI = -0.85, -0.16], t = -2.93, p = 0.004, ΔR2 = 0.09). These findings suggest that blacks are more susceptible to the impact of systolic prehypertension on white matter structural integrity.

Which out-of-office measurement technique should be used for diagnosing hypertension in prehypertensives? J Hum Hypertens 2019; 34:586-592. [PMID: 31700139 PMCID: PMC7423591 DOI: 10.1038/s41371-019-0284-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Revised: 10/24/2019] [Accepted: 10/25/2019] [Indexed: 01/17/2023]
Abstract
Hypertension (HT) is diagnosed with high office blood pressure (BP), although confirmation with the addition of out-of-office measurements is currently recommended. However, insufficient data are available concerning the use of out-of-office BP measurement techniques for the diagnosis of HT in the prehypertensive population. The aim of the present study was to determine which out-of-office measurements yielded earlier and more frequent detection of development of HT in prehypertensive patients. Two hundred seven prehypertensive patients under monitoring in the Cappadocia cohort were included in the study. Office BP was measured five times at 1-min intervals, followed by 24-h ambulatory BP monitoring (24-h ABPM). Home BP measurement (HBPM) was performed five times, at the same times in the morning and evening, at 1-min intervals for 1 week. The same procedure was carried out at 4–6-month intervals for ~2 years. HT was diagnosed in 25.6% of subjects, masked HT in 11.1%, and white coat HT in 2.9%, while 23.7% remained prehypertensive and 36.7% became normotensive. Briefly, 56.6% of the patients with HT were diagnosed with office plus 24-h ABPM, 13.2% with office plus HBPM, and 30.2% with office plus HBPM and 24-h ABPM. Office with 24-h ABPM yielded statistically significantly more diagnoses (p < 0.001). In conclusion, our prospective observational study evaluated the usefulness of out-of-office BP measurements in confirming diagnosis of HT in prehypertensive patients. The findings show that 24-h ABPM detected HT earlier and more frequently in this high-risk population.

Abstract
Black Americans suffer disproportionately from hypertension and hypertensive heart disease. Out-of-office blood pressure (BP) is more predictive for cardiovascular complications than clinic BP; however, the relative abilities of clinic and out-of-office BP to predict left ventricular hypertrophy in black and white adults have not been established. Thus, we aimed to compare associations of out-of-office and clinic BP measurement with left ventricular hypertrophy by cardiac magnetic resonance imaging among non-Hispanic black and white adults. In this cross-sectional study, 1262 black and 927 white participants of the Dallas Heart Study ages 30 to 64 years underwent assessment of standardized clinic and out-of-office (research staff-obtained) BP and left ventricular mass index. In multivariable-adjusted analyses of treated and untreated participants, out-of-office BP was a stronger determinant of left ventricular hypertrophy than clinic BP (odds ratio per 10 mm Hg, 1.48; 95% CI, 1.34-1.64 for out-of-office systolic BP and 1.15 [1.04-1.28] for clinic systolic BP; 1.71 [1.43-2.05] for out-of-office diastolic BP, and 1.03 [0.86-1.24] for clinic diastolic BP). Non-Hispanic black race/ethnicity, treatment status, and lower left ventricular ejection fraction were also independent determinants of hypertrophy. Among treated Blacks, the differential association between out-of-office and clinic BP with hypertrophy was more pronounced than in treated white or untreated participants. In conclusion, protocol-driven supervised out-of-office BP monitoring provides important information that cannot be gleaned from clinic BP assessment alone. Our results underscore the importance of hypertension management programs outside the medical office to prevent hypertensive heart disease, especially in high-risk black adults.

Abstract
BACKGROUND Hypertension and obesity have become a global issue and an important public health concern due to an unhealthy lifestyle. The present study aims to determine the prevalence of hypertension and its association with various adiposity indicators among Sunni Muslim population of Lucknow, Uttar Pradesh. MATERIALS AND METHODS A cross-sectional study was conducted among 214 individuals using purposive sampling method. Somatometric measurements were taken using the ISAK protocol. Correlation analysis and odds ratio were calculated to determine the best predictor of hypertension. RESULTS 41% of males and 42.1% of females were found to be in Stage-II hypertension. BMI and WC were found to have the highest correlation with SBP among males and females, respectively. WHR followed by WC and BMI, was found to be the strongest predictor of hypertension in males. In the case of females, WHtR Followed by, BMI and WHR were found to be the strongest predictors of hypertension. CONCLUSION Among the presently studied Muslim population of Lucknow, a high prevalence of hypertension was found among both males and females. Also, WHR among males and WC among females were found to be better predictors of hypertension. Thus, for better prediction of risk of hypertension, sex and ethnicity-specific adiposity indicator should be used in clinical practice.

Abstract
We conducted a cross-sectional study among school/college students in Tanzania and Uganda to determine the prevalence of high blood pressure (BP) and associated factors. Participants were classified to have high BP if they had pre-hypertension or hypertension. Interviews were done using the WHO STEPS instrument. Using data from both countries (n = 1596), the overall prevalence of high BP was 40% (95% CI: 37-42). The prevalence of pre-hypertension was 29% (95% CI: 26-31) and that of hypertension was 11% (95% CI: 10-13). High BP was independently associated with obesity (aOR = 6.7, 95% CI: 2.2-20.0), male sex (aOR = 3.2, 95% CI: 2.4-4.4), and among males aged above 20 years (aOR = 5.5, 95% CI: 2.9-10.5). Consumption of fruits/vegetables was associated with decreased odds for high BP (aOR = 0.7, 95% CI: 0.50-0.98). The increasing burden of pre-hypertension across age groups could explain the early onset of hypertension and cardiovascular diseases (CVDs) among young African adults. There is a need for longitudinal studies to explore the drivers of pre-hypertension in East African adolescents.

Association between resting heart rate and hypertension in Chinese with different waist-to-height ratio: a population-based cross-sectional study. JOURNAL OF THE AMERICAN SOCIETY OF HYPERTENSION : JASH 2018; 12:e93-e101. [PMID: 30268408 DOI: 10.1016/j.jash.2018.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Revised: 08/13/2018] [Accepted: 08/26/2018] [Indexed: 06/08/2023]
Abstract
Elevated resting heart rate (RHR) and obesity are important risk factors for hypertension. However, studies are rare on the combined impact of RHR and obesity on prehypertension and hypertension. This study aimed to investigate the association between RHR and hypertension with different waist-to-height ratio (WHtR) in Chinese. The population-based cross-sectional study was conducted during 2013-2015 in Henan province, China, and 15,536 participants aged ≥15 years were included. RHR was classified according to sex-specific quartiles. The cutoff value of WHtR was 0.5 in both sexes. Multilinear and multilogistic regression models were used to evaluate the association of RHR and WHtR with prehypertension and hypertension. In both sexes, higher RHR was associated with higher blood pressure and lower pulse pressure. Compared with the lowest RHR quartile, participants in the highest RHR quartile had an increased risk of prehypertension (odds ratio [OR]: 1.40, 95% confidence interval [CI]: 1.18-1.65; OR: 1.27, 95% CI: 1.09-1.48) and hypertension (OR: 1.75, 95% CI: 1.43-2.15; OR: 1.36, 95% CI: 1.13-1.63) for male and female, respectively, after fully adjusting the data. In addition, adjusted ORs for prehypertension and hypertension of participants with high WHtR and high RHR were 2.91 (95% CI: 2.38-3.55) and 6.28 (4.96-7.97) for male and 2.45 (2.05-2.93) and 4.63 (3.66-5.85) for female, respectively, compared with the normal WHtR and normal RHR. In conclusion, elevated RHR was significantly associated with the risk of prehypertension and hypertension in Chinese and WHtR as a measure of abdominal obesity further increased this association.

Cumulative Incidence of Hypertension by 55 Years of Age in Blacks and Whites: The CARDIA Study. J Am Heart Assoc 2018; 7:e007988. [PMID: 29997132 PMCID: PMC6064834 DOI: 10.1161/jaha.117.007988] [Citation(s) in RCA: 66] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 05/23/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND Blacks have higher blood pressure levels compared with whites beginning in childhood. Few data are available on racial differences in the incidence of hypertension from young adulthood through middle age. METHODS AND RESULTS We calculated the cumulative incidence of hypertension from age 18 to 55 years among participants in the CARDIA (Coronary Artery Risk Development in Young Adults) study. Incident hypertension was defined by the first visit with mean systolic blood pressure ≥130 mm Hg, mean diastolic blood pressure ≥80 mm Hg, or self-reported use of antihypertensive medication. Among 3890 participants without hypertension at baseline (aged 18-30 years), cumulative incidence of hypertension by age 55 years was 75.5%, 75.7%, 54.5%, and 40.0% in black men, black women, white men, and white women, respectively. Among participants with systolic blood pressure/diastolic blood pressure <110 and 70, 110 to 119/70 to 74, and 120 to 129/75 to 79 mm Hg at baseline, blacks were more likely than whites to develop hypertension: multivariable-adjusted hazard ratios 1.97 (95% confidence interval, 1.65, 2.35), 1.80 (95% confidence interval, 1.52, 2.14), and 1.59 (95% confidence interval, 1.31, 1.93), respectively. Parental history of hypertension and higher body mass index, serum uric acid, and systolic blood pressure/diastolic blood pressure categories were associated with a higher risk for hypertension among blacks and whites. A higher Dietary Approaches to Stop Hypertension diet adherence score was associated with a lower risk for hypertension in blacks and whites. CONCLUSIONS Regardless of blood pressure level in young adulthood, blacks have a substantially higher risk for hypertension compared with whites through 55 years of age.

Predictors of Hypertension in Mauritians with Normotension and Prehypertension at Baseline: A Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15071394. [PMID: 30004467 PMCID: PMC6068703 DOI: 10.3390/ijerph15071394] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Revised: 06/26/2018] [Accepted: 06/27/2018] [Indexed: 11/16/2022]
Abstract
Information on the predictors of future hypertension in Mauritians with prehypertension is scant. The aim of this study was to analyze the 5-year and 11-year risk of hypertension and its predictors in people with normotension and prehypertension at baseline in Mauritius in 1987. This was a retrospective cohort study of 883 men and 1194 women of Mauritian Indian and Mauritian Creole ethnicity, aged 25–74 years old, free of hypertension at baseline in 1987 with follow-up examinations in 1992 and 1998 using the same methodology. The main outcome was 5- and 11-year risk of hypertension. Odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated. The 5-year risk of hypertension was 5.4-times higher in people with prehypertension compared with normotensive individuals at baseline. The corresponding odds for prehypertensive people at baseline regarding 11-year hypertension risk was 3.39 (95% CI 2.67–4.29) in the adjusted logistic regression models. Being of Creole ethnicity (OR 1.42; 95% CI 1.09–1.86) increased the 11-year odds of hypertension compared with the Indian population. It is of importance to screen for people with prehypertension and implement strategies to reduce their systolic blood pressure levels to the recommended levels of 120/80 mmHg. Special attention needs to be given to Mauritians of Creole ethnicity.

Abstract
Vascular endothelial growth factor (VEGF) inhibitors, including monoclonal antibodies and tyrosine kinase inhibitors (TKIs), are important as anticancer treatments through curbing tumour angiogenesis and growth. VEGF inhibitors have significant cardiovascular effects. By blocking VEGF receptors, ligands, or signal pathways, VEGF inhibitors disturb the balance between vasodilation and vasoconstriction, undermine endothelial cell integrity, and activate cardiomyocyte apoptosis. VEGF inhibitors increase risks of hypertension, heart failure, thromboembolism and arrhythmia. Genetic and geographic studies showed that genetic polymorphisms likely play significant predictive or prognostic roles in cardiovascular toxicity associated with VEGF inhibitors. This review updates current understandings of VEGF inhibitors on cardiovascular toxicity, explores potential mechanisms, and clarifies whether genetic or ethnic factors contribute to their adverse effects. Key Messages VEGF inhibitors disturb the balance between vasodilation and vasoconstriction, undermine endothelial cell integrity and activate cardiomyocyte apoptosis. VEGF inhibitors increase risks of hypertension, heart failure, thromboembolism and arrhythmia. Genetic and geographic studies showed that genetic polymorphisms likely play significant predictive or prognostic roles in cardiovascular toxicity associated with VEGF inhibitors.

Abstract
BACKGROUND African-American college students are less likely to meet recommended physical activity guidelines to promote health, and are at risk of overweight, obesity, and elevated blood pressure. Text messaging is an emerging international technology shown to engage college students, promote physical activity, and reduce health risks. PURPOSE To determine the feasibility of using text messaging to promote physical activity among African-American college students enrolled in a unique course focusing on lifestyle behaviors for a healthy heart. SAMPLE A purposive sample of 11 (n=4 male, n=7 female) African-American college students aged 18-25 years with cell phones capable of receiving messages was used in this study. METHODS A three-week text-message protocol was piloted using web-based software to evaluate feasibility with post-hoc grouping of participants into responders and non responders. Descriptive statistics and Mann-Whitney U-tests were used to analyze group differences. RESULTS There was an attrition rate of nearly 91%. Observed engagement was 50% among responders with compliance at 44.44%. Observed engagement and compliance rates were less than 2% among nonresponders. There were no statistically significant differences in underlying variable distributions between groups. Of practical importance, it was noted that prior to texting responder means were higher for walking physical activity, and lower for body mass index, while nonresponders had higher means for vigorous physical activity. CONCLUSION The literature review indicated that text messaging is a cost-effective technology that can be incorporated into health education courses on HBCU campuses, but this project suggested semester timing is pivotal to feasibility. Implications largely address tailoring text messages to maintain engagement and evaluating the effect of text messages on physical activity level, body mass index, and blood pressure.

Abstract
OBJECTIVE Hypertensive disorders in pregnancy signal an increased risk of cardiovascular disease for women. However, future hypertension risk among pregnant women with moderately elevated blood pressure (BP) is unknown. We examined associations among moderately elevated BP or hypertensive disorders during pregnancy and later prehypertension or hypertension. DESIGN Longitudinal cohort study. SETTING Five communities in Michigan, USA. SAMPLE Data are from pregnant women enrolled in the Pregnancy Outcomes and Community Health Study. We included 667 women with gestational BP measurements who participated in the POUCHmoms Study follow-up 7-15 years later. METHODS Moderately elevated BP was defined as two measures of systolic BP ≥ 120 mmHg or diastolic BP ≥80 mmHg among women without a hypertensive disorder. Weighted multinomial logistic regression models estimated odds of prehypertension or hypertension at follow-up, adjusted for maternal confounders and time to follow-up. MAIN OUTCOME MEASURES Prehypertension or hypertension. RESULTS Women meeting the moderately elevated BP criteria (64%) had significantly higher odds of hypertension at follow-up (adjusted odds ratio 2.6; 95% confidence interval 1.2-5.5). These increased odds were observed for moderately elevated BP first identified before or after 20 weeks of gestation, and for elevated systolic BP alone or combined with elevated diastolic BP. CONCLUSIONS Moderately elevated BP in pregnancy may be a risk factor for future hypertension. Pregnancy offers an opportunity to identify women at risk for hypertension who may not have been identified otherwise. TWEETABLE ABSTRACT Moderately elevated blood pressure in pregnancy may be associated with hypertension later in life.

Abstract
Prehypertension is associated with increased risk for hypertension and cardiovascular disease. Data are limited on the temporal changes in the prevalence of prehypertension and risk factors for hypertension and cardiovascular disease among US adults with prehypertension. We analyzed data from 30 958 US adults ≥20 years of age who participated in the National Health and Nutrition Examination Surveys between 1999 and 2012. Using the mean of 3 blood pressure (BP) measurements from a study examination, prehypertension was defined as systolic BP of 120 to 139 mm Hg and diastolic BP <90 mm Hg or diastolic BP of 80 to 89 mm Hg and systolic BP <140 mm Hg among participants not taking antihypertensive medication. Between 1999-2000 and 2011-2012, the percentage of US adults with prehypertension decreased from 31.2% to 28.2% (P trend=0.007). During this time period, the prevalence of several risk factors for cardiovascular disease and incident hypertension increased among US adults with prehypertension, including prediabetes (9.6% to 21.6%), diabetes mellitus (6.0% to 8.5%), overweight (33.5% to 37.3%), and obesity (30.6% to 35.2%). There was a nonstatistically significant increase in no weekly leisure-time physical activity (40.0% to 43.9%). Also, the prevalence of adhering to the Dietary Approaches to Stop Hypertension eating pattern decreased (18.4% to 11.9%). In contrast, there was a nonstatistically significant decline in current smoking (25.9% to 23.2%). In conclusion, the prevalence of prehypertension has decreased modestly since 1999-2000. Population-level approaches directed at adults with prehypertension are needed to improve risk factors to prevent hypertension and cardiovascular disease.

Abstract
Despite four decades of research, there is no systematic review and trend analysis on paediatric (pre)hypertension in Nigeria. This article reviewed data from cross-sectional studies on the subject. From the initial 9334 articles identified, 30 studies that met the inclusion criteria were systematically reviewed. Data from studies that defined hypertension as blood pressure (BP) greater than the 95th percentile for age, height and sex gave a prevalence of 8.2% [95% confidence interval (CI): 3.6-28.2%] for prehypertension and 5.1% (95% CI: 2.9-8.6%) for hypertension. For studies that defined hypertension as BP greater than 2 SD points from the mean of the population, the prevalence of hypertension was found to be 4.0% (95% CI: 2.8-5.7%). A significant negative trend (Z = -0.89; α < 0.01) with small magnitude (Q = -0.019; 95% CI: -0.070 to 0.028) was found for hypertension in the reviewed population. The prevalence of (pre)hypertension in Nigerian children and adolescents is moderate but has slightly declined over time.

Abstract
BACKGROUND Physical activity (PA) has been associated with decreased left ventricular (LV) hypertrophy in previous studies. However, little is known about the relationship between PA and LV structure and factors which influence this relationship among African Americans. METHODS We evaluated 1,300 African Americans with preserved LV ejection fraction (EF > 50%) from the Genetic Epidemiology Network of Arteriopathy (GENOA) Study (mean age 62.4 years, 73% women). PA index was calculated as 3 * heavy activity hours + 2 * moderate activity hours + slight activity hours/day. The relationship between PA index and LV structure was evaluated using generalized estimating equation. The association between PA index and LV mass index by age group, sex, body mass index (BMI), history of hypertension, diabetes or coronary heart disease, estimated glomerular filtration rate, and current smoking status were plotted. RESULTS After adjustment for these factors, higher PA index was independently associated with lower LV mass index (P < 0.05). There were significant interactions between PA index and obesity (BMI ≥ 30) and history of hypertension on LV mass index (P for interaction <0.05, for both). Higher PA index was associated with lower LV mass index more in obese or hypertensive participants compared with nonobese or nonhypertensive participants. CONCLUSIONS Higher PA index was associated with reduced LV hypertrophy in obese and hypertensive African Americans. Prospective studies aimed at assessing whether increasing PA prevents LV hypertrophy and potentially reduces the risk of heart failure in these at risk groups are warranted.

Association between G-protein β3 subunit gene and isolated systolic blood pressure elevation of greater than 130 mmHg: A large-scale cross-sectional study in the Japanese population. World J Hypertens 2017; 7:24-31. [DOI: 10.5494/wjh.v7.i2.24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2016] [Revised: 12/22/2016] [Accepted: 02/13/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate whether GNB3 C825T single nucleotide polymorphism (SNP) contributes to systolic blood pressure (SBP) ≥ 130 mmHg in a large-scale cross-sectional study among the Japanese population with diastolic blood pressure (DBP) < 85 mmHg.
METHODS We analyzed 11008 Japanese subjects, including 2797 cases (SBP ≥ 130 and DBP < 85 mmHg) who were not taking anti-hypertensive medication and 8211 controls (SBP < 130 and DBP < 85 mmHg), all of whom enrolled in the genome banking project of the 21st Century COE (Center of Excellence) Program at Jichi Medical University. Subjects were divided into four groups according to gender (male and female) and age (≤ 49 years and ≥ 50 years). GNB3 gene polymorphism was determined using the TaqMan probe method. We compared the frequencies of alleles and genotypes between cases and controls by chi-squared test. The strength of the associations was estimated by odds ratios (ORs) and 95%CI by using logistic regression analysis. The ORs were adjusted for age and body mass index.
RESULTS Allele and genotype distributions significantly differed between cases and controls only in males aged ≤ 49 years. Compared to the CC genotype, a significant OR was obtained in the TT genotype among males aged ≤ 49 years.
CONCLUSION This study indicates that the TT genotype of the GNB3 C825T SNP may contribute to SBP elevation of greater than 130 mmHg compared to the CC genotype in Japanese males aged ≤ 49 years.

Abstract
OBJECTIVE Prehypertension is associated with increased risk for incident hypertension. However, little is known about how frequently prehypertension converts to normotension, and which variables predict this conversion. METHODS We identified 186 Japanese Americans with prehypertension (110 men, 76 women) aged 34-75 years (mean age of 52.3 years) who were followed at 5 and 10 years after enrollment. Blood pressure was measured with a mercury sphygmomanometer and average blood pressure was calculated. Subcutaneous adipose tissue, visceral adipose tissue (VAT), and subcutaneous thigh adipose tissue area were measured by computed tomography. RESULTS Approximately one-third of those with prehypertension converted to normotension over 10 years of follow-up. Those who converted to normotension were younger, less obese, and had significantly lower baseline SBP, fasting glucose, cholesterol levels, and homeostasis model assessment insulin resistance compared with study participants who continued to have prehypertension or progressed to hypertension. With regard to body fat compartments, study participants with conversion to normotension showed a significantly smaller VAT area compared with the nonconversion group (P < 0.001); but, subcutaneous adipose tissue and subcutaneous thigh adipose tissue were not significant. In multivariate logistic regression analysis, baseline VAT was inversely associated with the conversion independent of age, sex, waist circumference, diabetes, fasting glucose, homeostasis model assessment insulin resistance, non-high-density lipoprotein cholesterol, and SBP [odds ratio per 1 SD VAT increment (95% confidence interval), 0.35 (0.15-0.80), P = 0.012]. CONCLUSION This is the first prospective study showing the role of body fat distribution, determined by computed tomography scan, in predicting the natural history of prehypertension. Baseline VAT was inversely and independently associated with the conversion to normal blood pressure. No other adipose variable was significant. The mechanisms responsible for these observations remain to be elucidated.

Abstract
Although cell phone use and Internet access via cell phone is not marked by racial disparities, little is known about how cell phone use relates to blood pressure and health information seeking behaviors. The purposes of this study were to (a) describe Internet activities, cell phone use, and information seeking; (b) determine differences in blood pressure and information seeking between cell phone information seekers and nonseekers; and (c) examine cell phone information seeking as a predictor of blood pressure in African American women. Participants ( N = 147) completed a survey and had their blood pressure measured. Independent-sample t tests showed a significant difference in systolic blood pressure in cell phone information seekers and nonseekers. Linear regression revealed cell phone information seeking as an independent predictor of systolic blood pressure, despite confounders. It is possible that cell phone information seekers were using health information to make decisions about self-management of blood pressure.

Abstract
Oxidant stress contributes to the initiation and progression of hypertension (HTN) by enhancing endothelial dysfunction and/or causing perturbations in nitric oxide homeostasis. Differences in mitochondrial function may augment this process and provide insight into why age of onset and clinical outcomes differ among individuals from distinct ethnic groups. We have previously demonstrated that variation in normal mitochondrial function and oxidant production exists in endothelial cells from individuals of Caucasian and African-American ethnicity and that this variation contributes to endothelial dysfunction. To model these distinct mitochondrial redox phenotypes, we used C57Bl/6N (6N) and C57Bl/6J (6J) mice that also display unique mitochondrial functional properties due to the differential expression nicotinamide nucleotide transhydrogenase (NNT). We demonstrate that the absence of NNT in 6J cells led to distinct mitochondrial bioenergetic profiles and a pro-oxidative mitochondrial phenotype characterized by increased superoxide production and reduced glutathione peroxidase activity. Interestingly, we found that 6J animals have significantly higher systolic blood pressure compared to 6N animals, and this difference is exacerbated by angiotensin II treatment. The changes in pressure were accompanied by both mitochondrial and vascular dysfunction revealed by impaired respiratory control ratios and endothelial-dependent vessel dilation. All end points could be significantly ameliorated by treatment with the mitochondria-targeted superoxide dismutase mimetic MitoTEMPO demonstrating a critical role for the production of mitochondrial reactive oxygen species in the development of HTN in these animals. Taken together, these data indicate that the absence of NNT leads to variation in mitochondrial function and contributes to a unique mitochondrial redox phenotype that influences susceptibility to HTN by contributing to endothelial and vascular dysfunction.

Abstract
Masked hypertension, defined as nonelevated clinic blood pressure (BP) and elevated out-of-clinic BP may be an intermediary stage in the progression from normotension to hypertension. We examined the associations of out-of-clinic BP and masked hypertension using ambulatory BP monitoring with incident clinic hypertension in the Jackson Heart Study, a prospective cohort of blacks. Analyses included 317 participants with clinic BP <140/90 mm Hg, complete ambulatory BP monitoring, who were not taking antihypertensive medication at baseline in 2000 to 2004. Masked daytime hypertension was defined as mean daytime blood pressure ≥135/85 mm Hg, masked night-time hypertension as mean night-time BP ≥120/70 mm Hg, and masked 24-hour hypertension as mean 24-hour BP ≥130/80 mm Hg. Incident clinic hypertension, assessed at study visits in 2005 to 2008 and 2009 to 2012, was defined as the first visit with clinic systolic/diastolic BP ≥140/90 mm Hg or antihypertensive medication use. During a median follow-up of 8.1 years, there were 187 (59.0%) incident cases of clinic hypertension. Clinic hypertension developed in 79.2% and 42.2% of participants with and without any masked hypertension, 85.7% and 50.4% with and without masked daytime hypertension, 79.9% and 43.7% with and without masked night-time hypertension, and 85.7% and 48.2% with and without masked 24-hour hypertension, respectively. Multivariable-adjusted hazard ratios (95% confidence interval) of incident clinic hypertension for any masked hypertension and masked daytime, night-time, and 24-hour hypertension were 2.13 (1.51-3.02), 1.79 (1.24-2.60), 2.22 (1.58-3.12), and 1.91 (1.32-2.75), respectively. These findings suggest that ambulatory BP monitoring can identify blacks at increased risk for developing clinic hypertension.

Abstract
The purpose of this study was to describe physical activity (PA) behaviors and physical functioning of prehypertensive and Stage I hypertensive African American Women (AAW) and to examine the relationships between PA behavior, physical functioning, personal factors, and behavior-specific influences. Pender's Health Promotion Model was the conceptual framework for the study. A cross-sectional design and convenience sample were used. The PA domain where the greatest amount of time was spent was in work-related activity, followed by household, leisure time, and transportation activity. Personal factors most strongly correlated to lower PA were greater body mass index and waist circumference. AAW perceived moderate barriers to PA and minimal family and friend social support for PA. Future interventions need to focus on removing barriers to and improving social support for PA among AAW.

Abstract
Background Studies consisting mostly of whites have shown that the prevalence of masked hypertension differs by prehypertension status. Using data from the Jackson Heart Study, an exclusively African American population‐based cohort, we evaluated the association of masked hypertension and prehypertension with left ventricular mass index and common carotid intima media thickness. Methods and Results At the baseline visit, clinic blood pressure (CBP) measurement and 24‐hour ambulatory blood pressure monitoring were performed. Masked hypertension was defined as mean systolic/diastolic CBP <140/90 mm Hg and mean daytime systolic/diastolic ambulatory blood pressure ≥135/85 mm Hg. Clinic hypertension was defined as mean systolic/diastolic CBP ≥140/90 mm Hg. Normal CBP was defined as mean systolic/diastolic CBP <120/80 mm Hg and prehypertension as mean systolic/diastolic CBP 120 to 139/80 to 89 mm Hg. The analytic sample included 909 participants. Among participants with systolic/diastolic CBP <140/90 mm Hg, the prevalence of masked hypertension and prehypertension was 27.5% and 62.4%, respectively. The prevalence of masked hypertension among those with normal CBP and prehypertension was 12.9% and 36.3%, respectively. In a fully adjusted model, which included prehypertension status and antihypertensive medication use as covariates, left ventricular mass index was 7.94 g/m2 lower among those without masked hypertension compared to participants with masked hypertension (P<0.001). Left ventricular mass index was also 4.77 g/m2 lower among those with clinic hypertension, but this difference was not statistically significant (P=0.068). There were no significant differences in left ventricular mass index between participants with and without masked hypertension, or clinic hypertension. Conclusions Masked hypertension was common among African Americans with prehypertension and also normal CBP, and was associated with subclinical cardiovascular disease.
