BACKGROUND
Although the prevalence of hypertension (HTN) continues to increase in developing countries, including China, recent data are lacking. A nationwide survey was conducted from October 2012 to December 2015 to assess the prevalence of HTN in China.
METHODS
A stratified multistage random sampling method was used to obtain a nationally representative sample of 451 755 residents ≥18 years of age from 31 provinces in mainland China from October 2012 to December 2015. Blood pressure (BP) was measured after resting for 5 minutes by trained staff using a validated oscillometric BP monitor. HTN was defined as systolic BP (SBP) ≥140 mm Hg/or diastolic BP (DBP) ≥90 mm Hg or use of antihypertensive medication within 2 weeks. Pre-HTN was defined as SBP 120 to 139 mm Hg and DBP 80 to 89 mm Hg without antihypertensive medication. HTN control was defined as SBP <140 mm Hg and DBP<90 mm Hg. In addition, the prevalence of HTN (SBP ≥130 or DBP ≥80 mm Hg) and control rate (SBP <130 and DBP <80 mm Hg) of HTN were also estimated according to the 2017 American College of Cardiology/American Heart Association High Blood Pressure Guideline.
RESULTS
Overall, 23.2% (≈244.5 million) of the Chinese adult population ≥18 years of age had HTN, and another 41.3% (≈435.3 million) had pre-HTN according to the Chinese guideline. There were no significant differences of HTN prevalence between urban and rural residents (23.4% versus 23.1%, =0.819). Among individuals with HTN, 46.9% were aware of their condition, 40.7% were taking prescribed antihypertensive medications, and 15.3% had controlled HTN. Calcium channel blockers were the most commonly used antihypertensive medication (46.5%) as monotherapy, and 31.7% of treated hypertensive patients used ≥2 medications. The prevalence of HTN based on the 2017 American College of Cardiology/American Heart Association guideline was twice as high as that based on 2010 Chinese guideline (46.4%), whereas the control rate fell to 3.0%.
CONCLUSIONS
In China, there is a high prevalence of HTN and pre-HTN, and awareness, treatment, and control of HTN were low. Management of medical therapy for HTN needs to improve.

Meta-Analysis
Background Nonpharmacologic interventions that modify lifestyle can lower blood pressure (BP) and have been assessed in numerous randomized controlled trials and pairwise meta-analyses. It is still unclear which intervention would be most efficacious. Methods and Results Bayesian network meta-analyses were performed to estimate the comparative effectiveness of different interventions for lowering BP. From 60 166 potentially relevant articles, 120 eligible articles (14 923 participants) with a median follow-up of 12 weeks, assessing 22 nonpharmacologic interventions, were included. According to the surface under the cumulative ranking probabilities and Grading of Recommendations Assessment, Development and Evaluation (GRADE) quality of evidence, for adults with prehypertension to established hypertension, high-quality evidence indicated that the Dietary Approach to Stop Hypertension (DASH) was superior to usual care and all other nonpharmacologic interventions in lowering systolic BP (weighted mean difference, 6.97 mm Hg; 95% credible interval, 4.50-9.47) and diastolic BP (weighted mean difference, 3.54 mm Hg; 95% credible interval, 1.80-5.28). Compared with usual care, moderate- to high-quality evidence indicated that aerobic exercise, isometric training, low-sodium and high-potassium salt, comprehensive lifestyle modification, breathing-control, and meditation could lower systolic BP and diastolic BP. For patients with hypertension, moderate- to high-quality evidence suggested that the interventions listed (except comprehensive lifestyle modification) were associated with greater systolic BP and diastolic BP reduction than usual care; salt restriction was also effective in lowering both systolic BP and diastolic BP. Among overweight and obese participants, low-calorie diet and low-calorie diet plus exercise could lower more BP than exercise. Conclusions DASH might be the most effective intervention in lowering BP for adults with prehypertension to established hypertension. Aerobic exercise, isometric training, low-sodium and high-potassium salt, comprehensive lifestyle modification, salt restriction, breathing-control, meditation and low-calorie diet also have obvious effects on BP reduction.

PURPOSE
This systematic umbrella review examines and updates the evidence on the relationship between physical activity (PA) and blood pressure (BP) presented in the 2008 Physical Activity Guidelines Advisory Committee Scientific Report.
METHODS
We performed a systematic review to identify systematic reviews and meta-analyses involving adults with normal BP, prehypertension, and hypertension published from 2006 to February 2018.
RESULTS
In total, 17 meta-analyses and one systematic review with 594,129 adults ≥18 yr qualified. Strong evidence demonstrates: 1) an inverse dose-response relationship between PA and incident hypertension among adults with normal BP; 2) PA reduces the risk of cardiovascular disease (CVD) progression among adults with hypertension; 3) PA reduces BP among adults with normal BP, prehypertension, and hypertension; and 4) the magnitude of the BP response to PA varies by resting BP, with greater benefits among adults with prehypertension than normal BP. Moderate evidence indicates the relationship between resting BP and the magnitude of benefit does not vary by PA type among adults with normal BP, prehypertension, and hypertension. Limited evidence suggests the magnitude of the BP response to PA varies by resting BP among adults with hypertension. Insufficient evidence is available to determine if factors such as sex, age, race/ethnicity, socioeconomic status, and weight status or the frequency, intensity, time, and duration of PA influence the associations between PA and BP.
CONCLUSIONS
Future research is needed that adheres to standard BP measurement protocols and classification schemes to better understand the influence of PA on the risk of comorbid conditions, health-related quality of life, and CVD progression and mortality; the interactive effects between PA and antihypertensive medication use; and the immediate BP-lowering benefits of PA.

Review
Diaphragmatic breathing, a deep breathing technique, has been reported to improve autonomic function by reducing sympathetic activity and increasing baroreflex sensitivity. This literature review aimed to (1) examine the effects of diaphragmatic breathing on physiological and psychological measures in prehypertensive or hypertensive adults and to (2) determine the appropriate length, frequency, and duration of an effective diaphragmatic breathing exercise in the management of prehypertension and hypertension. Relevant studies were searched using electronic databases, and 13 studies that met the inclusion criteria were included. The synthesis of the findings revealed that voluntary diaphragmatic deep breathing resulted in decreased of systolic and diastolic blood pressures, reduced heart rate, a relaxing effect, and reduced anxiety in hypertensive or prehypertensive individuals. It is concluded that voluntary diaphragmatic breathing at <10 or 6 breaths per minute for 10 min twice a day for 4 weeks was effective in producing positive outcomes. The results of this review provide directions for related interventions and future research.

Meta-Analysis Review
The chronic antihypertensive effect of resistance training (RT) has been widely recognized in mixed-aged populations. However, the specific effect of RT on blood pressure (BP) in older individuals (≥60 years) remains unknown. Therefore, this meta-analysis of randomized controlled trials explored the chronic effects of dynamic RT alone on BP in older people. The study followed the PRISMA statement, and the search was performed using MeSH terms "strength training", "blood pressure" and "aged" on MEDLINE (PubMed), SCOPUS, and Web of Science databases. From 1783 potential articles, 24 studies met all inclusion criteria resulting in 835 participants randomized into 26 RT interventions (n = 430) and 24 control groups (n = 405). Overall, BP reduction favoring RT was observed both in SBP (-6.88 [-10.02, -3.73] mmHg) and DBP (-3.37 [-4.71, -2.22] mmHg). Subgroup analysis revealed BP decreases in both participants with hypertension (SBP: -10.42 [-15.67, -5.17]; DBP: -3.99 [-5.76,-2.22] mmHg), and prehypertension (SBP: -4.87 [-7.76, -1.98]; DBP: -2.77 [-4.88, -0.66] mmHg). Improvement in BP was found in studies using traditional RT (free weights and machines) (SBP: -7.04 [-11.04, -3.05]; DBP: -2.60 [-3.72, -1.47] mmHg) and elastic band interventions (SBP: -2.79 [-3.72, -1.86]; DBP:-1.68 [-3.18, -0.18] mmHg). RT performed at moderate intensity (60-80 % 1RM) reduced SBP (-6.98, [-11.93, -2.03]mmHg) and DBP (-3.64 [-5.11, -2.18] mmHg). In conclusion, RT can reduce BP in older people at prehypertensive and hypertensive stage, with traditional RT performed with moderate loads leading to an effect estimate of approximately -7 mmHg for SBP and -4 mmHg for DBP.

Randomized Controlled Trial
Different exercise training modalities produce similar endothelial function improvements in individuals with prehypertension or hypertension: a randomized clinical trial Exercise, endothelium and blood pressure.
Endothelial dysfunction is a characteristic of systemic arterial hypertension (SAH) and an early marker of atherosclerosis. Aerobic exercise training (AT) improves endothelial function. However, the effects of resistance training (RT) and combined training (CT) on endothelial function remain controversial in individuals with SAH. We determined the effects of AT, RT, and CT on endothelial function and systolic (SBP)/diastolic blood pressure (DBP) in individuals with prehypertension or hypertension. Forty-two participants (54 ± 11 y, resting SBP/DBP 137 ± 9/86 ± 6 mmHg) were randomly allocated into AT (n = 14, 40 min of cycling, 50-75% heart rate reserve), RT (n = 14, 6 resistance exercises, 4 × 12 repetitions, 60% maximum strength) and CT (n = 14, 2 × 12 repetitions of RT + 20 min of AT). All participants performed a 40-minute exercise session twice a week for 8 weeks. Endothelial function was evaluated by brachial artery flow-mediated dilation (FMD). Blood pressure was evaluated through ambulatory monitoring for 24 hours. After 8 weeks of exercise training, blood pressure was reduced in all 3 groups: -5.1 mmHg in SBP (95%CI -10.1, 0.0; p = 0.003) in AT; -4.0 mmHg in SBP (95%CI -7.8, -0.5; p = 0.027) in RT; and -3.2 mmHg in DBP (95%CI -7.9, 1.5; p = 0.001) in CT. All 3 exercise training modalities produced similar improvements in FMD: + 3.2% (95%CI 1.7, 4.6) (p < 0.001) in AT; + 4.0% (95%CI 2.1, 5.7) (p < 0.001) in RT; and +6.8% (95%CI 2.6, 11.1) (p = 0.006) in CT. In conclusion, different exercise training modalities were similarly effective in improving endothelial function but impacts on ambulatory blood pressure appear to be variable in individuals with prehypertension or hypertension.

Randomized Controlled Trial
Prevalence of pre-hypertension is higher among young adults and may increase the risk for hypertension and cardiovascular morbidity. Music therapy has been investigated to reduce the blood pressure in the hypertensive population; however, its efficacy on blood pressure in pre-hypertensive young adults is not known. Thirty pre-hypertensive (systolic blood pressure [SBP] = 120-139 mmHg and diastolic blood pressure [DBP] = 80-89 mmHg) young adults were recruited and randomly assigned into two groups. Music group (N = 15) received music therapy by passive listening to music for 30 minutes/day, 5 days/week for 4 weeks, along with Dietary Approaches to Stop Hypertension (DASH) eating plan (a diet rich in fruits and vegetables, low-fat dairy or unsaturated fat) and limit the daily sodium intake less than 100 mmol/day. The control group (N = 15) practiced only DASH eating plan and sodium restriction. The SBP, DBP, and heart rate (HR) were measured before and after 4 weeks of intervention. There was a significant reduction in SBP (8.73 mmHg, p < .001) and HR (6.42 beats/minute, p = .002); however, the reduction in DBP (1.44 mmHg, p = .101) was not statistically significant in the music group. Control group did not exhibit any significant reduction in SBP (0.21 mmHg, p < .836), DBP (0.81 mmHg, p < .395) and HR (0.09 beats/minute, p < .935). In conclusion, music therapy reduced significantly SBP and HR suggesting that it could be a promising tool to prevent the progression of pre-hypertension toward hypertension among young adults.

Review
Even though several studies have implicated the role of inflammation in the pathogenesis of hypertension and other cardiovascular disease, there are only limited studies about inflammatory markers in prehypertension. The objective of the present article was to review the role of markers like C-reactive protein, interleukin-6, tumor necrosis factor-α and sialic acid in prehypertension. An extensive literature search was made in Pubmed (http://www.ncbi.nlm.nih.gov/pubmed/) using phrases such as prehypertension, inflammation, C-reactive protein, cardiovascular disease, cytokines and sialic acid. Several investigators have reported increased inflammatory markers like C-reactive protein, interleukin-6, tumor necrosis factor-α and sialic acid in prehypertension indicating the role of inflammation in the pathogenesis of prehypertension and its complications. Elevated inflammatory markers may enhance the risk for cardiovascular disease in subjects with prehypertension.

Randomized Controlled Trial
IMPORTANCE
Prehypertension increases the risk of developing hypertension and other cardiovascular diseases. Early and effective intervention for patients with prehypertension is highly important.
OBJECTIVE
To assess the efficacy of Tai Chi vs aerobic exercise in patients with prehypertension.
DESIGN, SETTING, AND PARTICIPANTS
This prospective, single-blinded randomized clinical trial was conducted between July 25, 2019, and January 24, 2022, at 2 tertiary public hospitals in China. Participants included 342 adults aged 18 to 65 years with prehypertension, defined as systolic blood pressure (SBP) of 120 to 139 mm Hg and/or diastolic BP (DBP) of 80 to 89 mm Hg.
INTERVENTIONS
Participants were randomized in a 1:1 ratio to a Tai Chi group (n = 173) or an aerobic exercise group (n = 169). Both groups performed four 60-minute supervised sessions per week for 12 months.
MAIN OUTCOMES AND MEASURES
The primary outcome was SBP at 12 months obtained in the office setting. Secondary outcomes included SBP at 6 months and DBP at 6 and 12 months obtained in the office setting and 24-hour ambulatory BP at 12 months.
RESULTS
Of the 1189 patients screened, 342 (mean [SD] age, 49.3 [11.9] years; 166 men [48.5%] and 176 women [51.5%]) were randomized to 1 of 2 intervention groups: 173 to Tai Chi and 169 to aerobic exercise. At 12 months, the change in office SBP was significantly different between groups by -2.40 (95% CI, -4.39 to -0.41) mm Hg (P = .02), with a mean (SD) change of -7.01 (10.12) mm Hg in the Tai Chi group vs -4.61 (8.47) mm Hg in the aerobic exercise group. The analysis of office SBP at 6 months yielded similar results (-2.31 [95% CI, -3.94 to -0.67] mm Hg; P = .006). Additionally, 24-hour ambulatory SBP (-2.16 [95% CI, -3.84 to -0.47] mm Hg; P = .01) and nighttime ambulatory SBP (-4.08 [95% CI, -6.59 to -1.57] mm Hg; P = .002) were significantly reduced in the Tai Chi group compared with the aerobic exercise group.
CONCLUSIONS AND RELEVANCE
In this study including patients with prehypertension, a 12-month Tai Chi intervention was more effective than aerobic exercise in reducing SBP. These findings suggest that Tai Chi may help promote the prevention of cardiovascular disease in populations with prehypertension.

Hypertension is the most prevalent cardiovascular risk factor underlying atrial fibrillation and is present in up to 40% of patients with atrial fibrillation. Furthermore, attributable risk studies have shown that a history of hypertension contributes to up to 24% of incident atrial fibrillation. New data suggest that even early forms of hypertension (prehypertension and aortic stiffness) are associated with an increased risk of atrial fibrillation development. Hypertension and prehypertension are therefore critical mediators for the development of atrial fibrillation. Mechanisms for the association between hypertension and atrial fibrillation include diffuse electro-structural changes to the left atrium, driven by the haemodynamic and neurohormonal influences of hypertension and other, frequently coexisting, cardiovascular risk factors. Management of hypertension in atrial fibrillation should focus not only on blood pressure reduction but also on a comprehensive risk factor modification strategy. Such strategies have been shown to be associated with significant improvements in atrial fibrillation symptom burden as well as improved arrhythmia-free survival and reversal of the progression of atrial fibrillation. These strategies should focus on dietary modifications as well as prescribed exercise programmes involving a multidisciplinary team and patient-centred atrial fibrillation care. Risk factor management, supplemented by antihypertensive medications as needed, provides the optimum strategy for improving outcomes and even reversing the natural progression of atrial fibrillation in patients with hypertension.
