Prevalence Of Hypertension In China Research Articles

Characteristics of hypertension in the last 16 years in high prevalence region of China and the attribute ratios for cardiovascular mortality

BackgroundTianjin is one of the cities with the highest prevalence of hypertension in China and one of the first regions to develop community management of hypertension. Our aim was to analyze the characteristics of hypertension in the last 16 years, and estimate the population attributable fraction for cardiovascular mortality in Tianjin, China.MethodsWe compared the epidemiological characteristics of hypertension between 2002 and 2018 by analyzing data from the National Nutrition and Chronic Disease Risk Factor Survey. Subsequently, we obtained the cause-specific mortality in the same year from the Tianjin All Cause of Death Registration System (CDRS), and the population attributable fraction was used to estimate the annual cardiovascular disease (CVD) deaths caused by hypertension.ResultsIn 2002 and 2018, the crude prevalence, awareness, treatment rate in diagnosed, control rate in treated, and overall control rate of hypertension were 36.6% and 39.8%, 36.0% and 51.9%, 76.0% and 90.1%, 17.4% and 38.3%, 4.8% and 17.9%, respectively (P < 0.05). The mean SBP for males between the ages of 25 and 50 was significantly higher in 2018 than in 2002. The number of CVD deaths attributed to hypertension was 13.8 thousand in 2002 (account for 59.1% of total CVD deaths), and increased to 21.7 thousand in 2018 (account for 58.8% of total CVD deaths). The population attributable fraction have increased in the age groups of 25–44 and 75 and above, and decreased in the age group of 45–74 from 2002 to 2018.ConclusionsCompare to 2002, the proportion of CVD deaths attributed to hypertension remains high, particularly among younger and older people, despite a very significant increase in treatment and control rates for hypertension in 2018.

Hypertension in China: epidemiology and treatment initiatives.

The past two to three decades have seen a steady increase in the prevalence of hypertension in China, largely owing to increased life expectancy and lifestyle changes (particularly among individuals aged 35-44 years). Data from the China hypertension survey conducted in 2012-2015 revealed a high prevalence of grade 3 hypertension (systolic blood pressure ≥180 mmHg and diastolic blood pressure ≥110 mmHg) in the general population, which increased with age to up to 5% among individuals aged ≥65 years. The risk profile of patients with hypertension in China has also been a subject of intense study in the past 30 years. Dietary sodium and potassium intake have remained largely the same in China in the past three decades, and salt substitution strategies seem to be effective in reducing blood pressure levels and the risk of cardiovascular events and death. However, the number of individuals with risk factors for hypertension and cardiovascular disease in general, such as physical inactivity and obesity, has increased dramatically in the same period. Moreover, even in patients diagnosed with hypertension, their disease is often poorly managed owing to a lack of patient education and poor treatment compliance. In this Review, we summarize the latest epidemiological data on hypertension in China, discuss the risk factors for hypertension that are specific to this population, and describe several ongoing nationwide hypertension control initiatives that target these risk factors, especially in the low-resource rural setting.

Association Between Dietary Patterns and the Risk of Hypertension Among General Population in China and America

Hypertension is one of the risk factors of many diseases such as cardiovascular disease and stroke, and it has become increasingly prevalent worldwide. Although elevated blood pressure is related to many different factors, some studies have found that people's dietary patterns seem to be closely related to the development of hypertension. This paper aimed to compare the dietary patterns in China and America and to explore how they affect the incidence of hypertension in both countries. Through analysis, high sodium diets, substandard vegetable intake, and high-temperature cooking methods in both countries were found to be hazard factors that might increase the prevalence of hypertension. The difference was that the high sodium intake in America mainly comes from processed food, while the sodium intake in China mainly comes from salt added during cooking. In addition, the relatively high intake of whole-grain diet in China may also be one of the reasons for the relatively low prevalence of hypertension in China. In terms of intervention on hypertension, although America has higher compliance with the DASH diet, it is still important to popularize dietary guidelines and hypertension-related knowledge in order to help the public better improve their health status. However, the current research has no definite evidence to prove the relationship between diet and hypertension, so more research and data still need to be found.

Secular trends of population attributable risk of overweight and obesity for hypertension among Chinese adults from 1991 to 2011

We determined if the increasing trend in hypertension can be partly attributed to increasing prevalence of overweight/obesity in China over the past two decades. Data were collected from 1991 to 2011 and the population attributable risk (PAR), which is used to estimate the intervention effect on hypertension if overweight/obese, were eliminated. Linear regression was used to evaluate the secular trends. The age-standardized prevalence of overweight and obesity increased by 26.32% with an overall slope of 1.27% (95% CI: 1.12–1.43%) per year. Hypertension also increased by 12.37% with an overall slope of 0.65% (95% CI: 0.51–0.79%) per year. The adjusted ORs of overweight/obesity for hypertension across the survey years remained unchanged; however, the trend in PAR increased steadily from 27.1 to 44.6% with an overall slope of 0.81% (95% CI: 0.34–1.28%) per year (P = 0.006). There was no significant gender difference in the slopes of increasing PAR, as measured by regression coefficients (β = 0.95% vs. β = 0.63% per year, P = 0.36). Over the past two decades, the increase in the prevalence of hypertension in China was partly attributed to the overweight/obesity epidemic, which highlights the importance of controlling weight and further reducing the burden of hypertension.

Population and prevalence of hypertension in different regions of China

Hypertension is the most common chronic disease in the Chinese population. The study analyzes the differences of hypertension in different regions in China from space, analyzes the influencing factors of the disease, and the spatial distribution of different populations. The data comes from CHARLS Harmonize. 22,310 interviewees were selected to respond effectively. Single-factor chi-square test and binary logistic regression were used to analyze the factors affecting hypertension. BMI, urban and rural areas, jogging 1KM, smoking, drink, gender, education status, public medical insurance and hypertension chi-square test are significant, BMI (OR=1.193 95%CI 1.182~1.203), age (OR =1.049, 95%CI 1.045~1.053). There is a spatial difference in the prevalence of hypertension in China, which provides a spatial reference for the control and prevention of different regions, so as to better prevent and treat patients with hypertension.

Geographic variations in the blood pressure responses to short-term fine particulate matter exposure in China

Results from recent studies on associations between blood pressure (BP) and short-term exposure to fine particulate matter (PM2.5) have been inconsistent. Most studies have been evaluations of small geographic areas, with no national study in China.This study aimed to examine the acute BP responses to ambient PM2.5 among the general population of Chinese adults.During 2012–2015, systolic and diastolic BP levels were obtained from a large national representative sample, the China Hypertension Survey database (n = 479,842). Daily PM2.5 average exposures with a spatial resolution of 0.1° were estimated using a data assimilation that combines satellite measurements, air model simulations, and monitoring values.Overall, a 10-μg/m3 increase in daily PM2.5 was associated with a 0.035 (95% confidence interval: 0.020, 0.049) mmHg change in systolic BP and 0.001 (−0.008, 0.011) mmHg in diastolic BP after adjustments. Stratified by geographic regions, the systolic and diastolic BP levels varied from −0.050 (−0.109, 0.010) to 0.242 (0.176, 0.307) mmHg, and from −0.026 (−0.053, 0.001) to 0.051 (0.020, 0.082) mmHg, respectively. Statistically significant positive BP-PM2.5 associations were only found in South and North China for systolic levels and in Southwest China for diastolic levels. We further explored the regional study population characteristics and exposure-response curves, and found that the geographic variations in BP-PM2.5 associations were probably due to different population compositions or different PM2.5 exposure levels.Our study provided national-level evidence on the associations between ambient PM2.5 exposure and elevated BP levels. The magnitude of the estimated associations varied substantially by geographic location in China.

Effect of an intelligent family physician-optimised coordination model program on hypertension management in a Beijing community.

The prevalence of hypertension in China is increasing. To control chronic diseases, the Beijing Municipal Government implemented an intelligent family physician-optimised collaborative model (IFOCM). The present retrospective study assessed the effectiveness of the IFOCM in the management of hypertensive patients at the Fangzhuang Community Health Service Centre, Beijing. Using deidentified data from hypertensive patients, blood pressure (BP), BP control rate, 10-year risks of ASCVD, lifestyle changes and blood lipid levels were compared before and after implementation of the IFOCM. In all, 7332 patients with hypertension were included in the study. Systolic BP decreased from 144.59 to 142.96mmHg after program implementation (P<0.001), and the overall BP control rate increased from 41.43% to 46.49% (P<0.001). The proportion of patients predicted to be at a high 10-year risk of developing atherosclerotic cardiovascular disease decreased from 77.27% to 64.61% (P<0.001). After program implementation, body mass index decreased (from 24.87 to 24.36kg/m2; P<0.001), exercise frequency and intensity increased and salt intake, cigarette smoking, total cholesterol and low-density lipoprotein cholesterol all decreased significantly (P<0.001). The IFOCM program is effective in managing hypertension and providing timely patient care.

Spatio-Temporal Variation of Gender-Specific Hypertension Risk: Evidence from China.

Previous studies which have shown the existence of gender disparities in hypertension risks often failed to take into account the participants’ spatial and temporal information. In this study, we explored the spatio-temporal variation for gender-specific hypertension risks in not only single-disease settings but also multiple-disease settings. From the longitudinal data of the China Health and Nutrition Survey (CHNS), 70,374 records of 21,006 individuals aged 12 years and over were selected for this study. Bayesian B-spline techniques along with the Besag, York, and Mollie (BYM) model and the Shared Component Model (SCM) model were then used to construct the spatio-temporal models. Our study found that the prevalence of hypertension in China increased from 11.7% to 34.5% during 1991 and 2015, with a higher rate in males than that in females. Moreover, hypertension was found mainly clustered in spatially adjacent regions, with a significant high-risk pattern in Eastern and Central China while a low-risk pattern in Western China, especially for males. The spatio-temporal variation of hypertension risks was associated with regional covariates, such as age, overweight, alcohol consumption, and smoking, with similar effects of age shared by both genders whereas gender-specific effects for other covariates. Thus, gender-specific hypertension prevention and control should be emphasized in the future in China, especially for the elderly population, overweight population, and females with a history of alcohol consumption and smoking who live in Eastern China and Central China.

Asian management of hypertension: Current status, home blood pressure, and specific concerns in China.

Increasing life expectancy in the population means that the prevalence of hypertension in China will increase over the coming decades. Although awareness and control rates have improved, the absolute rates remain unacceptably low. Cardiovascular disease (CVD) is the biggest killer in China, and sharp increases in the prevalence of CVD risk factors associated with rapid lifestyle changes will contribute to ongoing morbidity and mortality. This highlights the importance of effectively diagnosing and managing hypertension, where home blood pressure monitoring (HBPM) has an important role. Use of HBPM in China is increasing, particularly now that Asia-specific guidance is available, and this out-of-office BP monitoring tool will become increasingly important over time. To implement these recommendations and guidelines, a Web-based and WeChat-linked nationwide BP measurement system is being established in China. Local guidelines state that both HBPM and ambulatory blood pressure monitoring should be implemented where available. In China, hypertension is managed most often using calcium channel blockers, followed by angiotensin receptor blockers or angiotensin-converting enzyme inhibitors. Key barriers to hypertension control in China are low awareness and control rates.

Chinese Physicians' Perspectives on the 2017 American College of Cardiology/American Heart Association Hypertension Guideline: A Mobile App-Based Survey.

Hypertension is a leading global risk factor for death and disability. Seeking new ways to prevent and treat hypertension is a priority for scientists and healthcare professionals worldwide. In November 2017, the American College of Cardiology (ACC) and the American Heart Association (AHA) issued a new hypertension guideline shifting the definition of hypertension from 140/90mmHg to 130/80mmHg for systolic/diastolic blood pressure. This new diagnostic threshold of hypertension has sparked a lively discussion worldwide over whether it should be applied in clinical settings to diagnose and treat hypertension. China, the world's most populous country, is facing a hypertension crisis. According to the 140/90mmHg guideline, China has an estimated 244.5 million population aged ≥18 years with hypertension, and another 435.3 million with pre-hypertension. If the new guideline is adopted, the prevalence of hypertension in China would double. This change would significantly impact patients, healthcare professionals, scientists, and policy makers in terms of the delivery of care and needed resources. This study aims to investigate whether Chinese physicians will use the 130/80mmHg threshold to diagnose hypertension in clinical practice. In March 2018, we launched a mobile app-based survey to study 253 Chinese physicians' perspectives on the ACC/AHA Guideline. A total of 253 physicians from 21 Chinese provinces completed the survey. Nearly 80% of the participants had already noticed the ACC/AHA guideline change. The proportion of participants who said they would use the new threshold to diagnoses hypertension was 41%, while 59% said they would not use the new threshold. The primary reason for those who said "yes" was that they believed early diagnosis of hypertension can trigger early actions to prevent the increasing blood pressure. For those who said "no", they argued that their decision was based on the fact that the Chinese Hypertension Prevention Guideline had not yet changed the diagnostic threshold from 140/90 to 130/80mmHg. Different understanding of hypertension prevention and treatment exists among Chinese physicians. It is an emergent need to form an evidence-based authoritative answer to guide Chinese physicians' future clinical practice.

Health perception and adherence with blood pressure control among rural Chinese adults with hypertension.

The aim of this study was to examine associations among blood pressure, personal and illness characteristics, illness perception and medication and self-management adherence among adults with hypertension in rural mainland China. Despite the high prevalence of hypertension in China, the control rate is only 20%. Identifying factors associated with blood pressure control is critical. Cross-sectional survey. Data were collected from 163 hypertensive adults in two rural villages in mainland China. Measures included a demographic questionnaire, the Chinese Illness-Perception Questionnaire-Revised, Medication Adherence Inventory and the Inventory of Adherence to Self-management. Height, weight, and blood pressure were also measured using standard approaches. Hierarchical linear regression was used to assess the association between blood pressure and significant variables identified in bivariate analysis. The mean systolic pressure observed in this sample was 147mmHg and the diastolic mean was 81mmHg. None of the variables analysed were associated with systolic blood pressure. Gender, age, and household annual income were associated with diastolic blood pressure, explaining 23% of the variance in the regression model. Illness coherence contributed an additional 2%. These findings suggest: (a) healthcare providers should focus on educating rural hypertensive adults about healthful diets and behaviours to manage hypertension, especially for those with high household income; (b) knowledge-based health education alone is not adequate; (c) illness perception may not be directly associated with blood pressure; and (d) the Chinese Illness-Perception Questionnaire-Revised and the Inventory of Adherence to Self-management require validation and potential revision for use with rural Chinese populations.

Comparing the income-related inequity of tested prevalence and self-reported prevalence of hypertension in China

BackgroundHypertension has become a global health challenge given its high prevalence and but low awareness and detection. Whether the actual prevalence of hypertension has been estimated is important, especially for the poor. This study aimed to measure tested prevalence and self-reported prevalence of hypertension and compare the inequity between them in China.MethodsData were derived from China Health and Nutrition Survey (CHNS) conducted in 2011. By using the multistage, stratified, random sampling method, 12,168 respondents aged 18 or older were identified for analysis. Both tested prevalence (systolic blood pressure ≥ 140 mmHg or/and diastolic blood pressure ≥ 90 mmHg or /and current use any of antihypertensive medication) and self-reported prevalence (ever diagnosed with hypertension by a doctor) were used to measure the prevalence of hypertension. The concentration index was employed to measure the extent of inequality in tested prevalence and self-reported prevalence. A decomposition method, based on a Probit model, was used to analyze income-related horizontal inequity of tested prevalence and self-reported prevalence.ResultsThe tested prevalence and self-reported prevalence of total respondents were 28.8% [95% CI (28.0%, 29.6%)] and 15.7% [95% CI (15.0%, 16.3%)], and 26.4% [95% CI (25.1%, 27.6%)] and 19.0% [95% CI (17.9%, 20.1%)] in urban areas, and 30.3% [95% CI (29.3%, 31.4%)] and 13.5% [95% CI (12.7%, 14.3%)] in rural areas. The horizontal inequity indexes of mean tested prevalence and self-reported prevalence were − 0.0494 and 0.1203 of total respondents, − 0.0736 and 0.0748 in urban area, and − 0.0177 and 0.0466 in rural area respectively, indicating pro-poor inequity in tested prevalence and pro-rich inequity in self-reported prevalence of hypertension. Economic status, education attainment and age were key factors of the pro-poor inequity in tested prevalence. Economic status, area and age were key factors to explain the poor-rich inequity in self-reported prevalence.ConclusionsThis study revealed self-reported prevalence of hypertension was much lower than tested prevalence in China, while a larger gap between self-reported and tested prevalence was found in rural areas. Our study suggested social strategies aiming at narrowing economic gap and regional disparities, reducing educational inequity, and facilitating health conditions of the elderly should be implemented. Finally, awareness raising campaigns to test hypertension in rural area need be strengthened by health education programs and improving the access to public health service, especially for those who do not engage with regular health checkups.

Status of Hypertension in China: Results From the China Hypertension Survey, 2012-2015.

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. 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. 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%, P=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%. 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.

Current and Future Hypertension Guidelines in China

According to the 4th National Nutrition and Health Survey in 2002, the prevalence of hypertension in China was 18.8%. Although there are no recent updated nationwide data, it is believed that the prevalence of hypertension has increased substantially in the past decade to more than 200 million hypertensive patients in the most populous country in China. To fight against the growing risk of hypertension, three Chinese hypertension guidelines were compiled in the past two decades, respectively, in 1999, 2005, and 2011. The current guidance document for the management of hypertension was named “2010 Chinese hypertension guideline” but published in 2011. In this guideline, all five classes of antihypertensive drugs were recommended as possible initial and maintenance therapies. The goal of treatment was a systolic/diastolic blood pressure below 140/90 mm Hg in general, 130/80 mm Hg in various groups of high-risk patients, and 150/90 mm Hg in the elderly (≥65 years). With the recent publication of several national and international hypertension guidelines, the Chinese guideline is now being considered for updates

Prevalence of hypertension in China

Hypertension has become a growing public health concern in rapidly developing countries. We estimated trends of hypertension prevalence in adults in China over the past 10 years and identified demographical and geographical determinants of these trends. A systematic search was conducted for studies published between 2002 and 2012 using PubMed and China National Knowledge Infrastructure electronic databases. In total, 47 studies were selected out of 4512 hits. The age-standardized prevalence of hypertension increased by 1.4% per year. Hypertension prevalence in north China was 9.1% (95% confidence interval 4.1-14.1), which was higher than south China. After adjustments for survey year and region, the age-standardized prevalence of hypertension did not differ significantly between men and women (P = 0.18). Our findings suggest a significant increase in the prevalence of hypertension in China over the period of 2002-2012 with considerable regional differences within China.

Analysis on associated factors of uncontrolled hypertension among elderly hypertensive patients in Southern China: a community-based, cross-sectional survey.

BackgroundThe prevalence of hypertension in China has risen dramatically in recent decades, but it is not well understood if hypertension is adequately controlled in the elderly population in Southern China. A provincial survey was performed in order to estimate the prevalence of hypertension control and the associated factors in the elderly population.MethodsA cross-sectional survey was conducted in 6 community health service centers across 12 counties in Southern China from October 2010 to April 2011. Recruitment included a total of 10644 hypertensive subjects aged 60 or older. Basic lab tests and physical examinations were administrated on each subject. In addition, each subject completed a standardized questionnaire.ResultsThe 10644 participants (mean age of 70.3 years) included 5527 women (51.9%), 5117 men (48.1%), 3148 overweight subjects (29.57%), 846 (7.95%) obese subjects, 1654 smokers (15.54%) and 1750 consumers of alcohol (16.44%). The control, treatment and awareness of hypertension were 44.6%, 50.3% and 46.3%, respectively. Most treated hypertensives (68.57%) used combination therapy of antihypertensive medications, and those using long-acting antihypertensive medications had a higher rate of adequately controlled hypertension. Results showed that elderly, living in rural and suburban areas, low education level, family history of hypertension, smoking, excessive salt consumption, lack of physical activity, overweight, obese and diabetes were associated with uncontrolled hypertension.ConclusionsLack of adequate hypertension control is relatively high among the elderly in Southern China. Hypertension awareness and early treatment are needed in this population, especially among suburban population, as well as adopting appropriate antihypertensive medication therapy and healthy lifestyles.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2458-14-903) contains supplementary material, which is available to authorized users.

Survey on prevalence of hypertension in China: Background, aim, method and design

Cardiovascular disease (CVD) is the first cause of death worldwide [1] and in China [2] as well. It is estimated that there are 230million people with CVD in China [3]. Hypertension is one of the major risk factors of CVD. The prevalence of hypertension was 5.1% in 1959, rising to 7.7% in 1979, 13.6% in 1991, and 18.8% in 2002; there were an estimated 160million patients in 2002 [4]. The awareness, treatment and control of hypertension were only 30%, 25% and 6%, respectively [5]. With the rapid economic development, urbanization, acceleration of population aging, and changes of traditional dietary habits and life style profile, it is expected that the prevalence of hypertension in China will continue to rise [3].

Prevalence of Hypertension in China: A Cross-Sectional Study

AimsThe present study aimed to assess the prevalence of hypertension among Chinese adults.MethodsData were obtained from sphygmomanometer measurements and a questionnaire administered to 46239 Chinese adults ≥20 years of age who participated in the 2007–2008 China National Diabetes and Metabolic Disorders Study. Hypertension was defined as blood pressure ≥140/90 mm Hg or use of antihypertensive medication.ResultsA total of 26.6% of Chinese adults had hypertension, and a significantly greater number of men were hypertensive than women (29.2% vs 24.1%, p<0.001). The age-specific prevalence of hypertension was 13.0%, 36.7%, and 56.5% among persons aged 20 to 44 years (young people), 45 to 64 years (middle-aged people), and ≥65 years (elderly people), respectively. In economically developed regions, the prevalence of hypertension was significantly higher among rural residents than among urban residents (31.3% vs 29.2%, p = 0.001). Among women or individuals who lived in the northern region, the disparity in the prevalence of hypertension between urban and rural areas disappeared (women: 24.0% vs. 24.0%, p = 0.942; northern region: 31.6% vs. 31.2%, p = 0.505). Among hypertensive patients, 45.0% were aware of their condition, 36.2% were treated, and 11.1% were adequately controlled.ConclusionsThe prevalence of hypertension in China is increasing. The trend of an increase in prevalence is striking in young people and rural populations. Hypertension awareness, treatment, and control are poor. Public health efforts for further improving awareness and enhancing effective control are urgently needed in China, especially in emerging populations.
