ABSTRACT: Objectives
To explore the prevalence, awareness, treatment and control rate of hypertension and analyse the potential social environment factors among Ngawa Tibetans in China.Design
This was a cross-sectional observational study.Setting
The investigation based on a multistage stratified cluster sampling was conducted in the Ngawa area, Sichuan Province, Southwest China. Tibetan residents were selected by random sampling method from one city and six counties in Ngawa.Methods
Basic demographical information, physical activity and blood pressure were collected. In addition, the participants completed the questionnaire. A multivariate logistic regression analysis was used to examine the association between the prevalence, awareness, treatment and control rate of hypertension and the potential risk factors.Participants
The sample comprised 2228 Ngawa Tibetan residents (age 18-80 years) from September 2018 to June 2019.Results
The prevalence rate of hypertension was 24.6%. The control rate was 6.2%, while the awareness rate (32.3%) and treatment rate (21.7%) of hypertension had been significantly improved.Conclusion
The prevalence of hypertension among Ngawa Tibetans was high. The awareness and treatment were improved in recent years. But the control rate was low. The government needs to strengthen the basic medical care and health education for Ngawa Tibetans.

Project description:ObjectivesAn understanding of the awareness, treatment and control of hypertension is helpful to guide decision-making regarding interventions to reduce the risk for diseases with hypertension as a key risk factor. This study aimed to estimate the prevalence, awareness, treatment, and control of hypertension in Shenzhen, China.MethodsA cross-sectional study was conducted. We employed multistage cluster random sampling methods to select participants. A survey involving face-to-face interviews was conducted to collect the data. A total of 1676 participants finished the survey and formed the final analysis.ResultsWe found that the prevalence of hypertension was 17.6%. The rates of hypertension awareness, treatment and control were 48.8%, 51.4% and 43.2%?respectively. Only 6.8% hypertensives were found to be managed by community health centres. Compared with the female participants, the males were found to have higher rates of prevalence (19.7% vs 15.7%; OR 1.47, 95% CI 1.10 to 1.97) and awareness (42.9% vs 38.1%; OR 2.35, 95% CI 1.28 to 4.33), but lower rates of medication treatments (20.5% vs 30.2%; OR 0.83, 95% CI 0.05 to 0.92) and control (12.8% vs 23.0%; OR 0.45, 95% CI 0.21 to 0.96). Migrants were more likely to be aware of hypertension (32.5% vs 44.3%; OR 0.57, 95% CI 0.30 to 0.90), reduce their salt intake (8.8% vs 18.1%; OR 0.40, 95% CI 0.15 to 0.94), and undertake regular monitoring of hypertension (1.3% vs 11.0%; OR 0.14, 95% CI 0.02 to 0.92) when compared with the locals.ConclusionsOur study finds that hypertension is an important public health burden in Shenzhen. It implies that strategies need to be developed to improve effective primary care management of hypertension. It also suggests a need to develop gender and household register tailored strategies for the prevention, detection, treatment and control of hypertension.

Project description:BackgroundIn recent decades, hypertension has become a popular public health problem in China. In 2017, a cross-sectional survey about hypertension and sodium intake measured by 24-hour (24-h) urine was launched in Zhejiang Province, to provide the basis of the Chinese population to develop a salt reduction intervention and prevention of hypertension strategy.MethodsCross-sectional data were obtained from 7512 participants aged 18 to 69 years in Zhejiang Province of China by complex, multistage sampling methods. The survey included face-to-face questionnaires and physical examination among all participants. Blood pressures and the use of anti-hypertension medications were used to determine hypertension. One thousand five hundred participants of them were asked to collect 24-h urine to measure sodium and potassium levels to assess intake. All rates and means were weighted by sampling weight and population structure of the province.ResultsThe weighted means of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 127.78 mm Hg (95% confidence interval [CI], 127.21-128.36) and 79.40 mm Hg (95%CI, 79.04-79.76). The weighted hypertension prevalence was 30.41% (95%CI, 28.91-31.91). Among those classified as having hypertension, 43.55% (95%CI, 40.77-46.34) were aware of the fact that they were suffering from hypertension, 32.05% (95%CI, 29.49-34.61) of them reported taking anti-hypertension medications, only 14.48% (95%CI, 12.54-16.42) had their blood pressure controlled. The weighted means of 24-h urinary sodium was 165.52 mmol (standard deviation [SD], 2.92), representing that the mean intake of sodium chloride was 9.68g (SD, 0.17) through conversion.ConclusionThese cross-sectional survey results show that hypertension and excessive sodium intake in adults are prevalent in Zhejiang Province, China. Salt reduction and prevention of hypertension is still an urgent public health work.

Project description:The aim of this study was to investigate factors associated with prevalence, awareness, treatment and control of hypertension in southern China. A cross-sectional, population-based survey was conducted in 180 villages across 15 counties in southern China from July to November 2010. Totally, 17437 persons completed all of the questionnaires, measurement examination and blood specimen collection. Adjusted rate of hypertension was 22.59% (95%CI: 22.52%-22.66%), for men 23.36% (95%CI: 23.25%-23.47%) and for women 21.77% (95%CI: 21.68%-21.86%). Multivariate logistic regression showed that old age, education attainment, alcohol use, diabetes, obesity, high TC and high TG were associated with hypertension. Among the hypertensive individuals, 54.33% were aware of their hypertension, and 46.34% were currently taking antihypertensive medication, but only 18.26% had their blood pressure controlled. Among all the hypertensive subjects, awareness was more common in those who were female, living in the urban, old age, low education attainment, diabetes, overweight, obese, Low HDL-C. Among the subjects aware of their diagnosis of hypertension, medication treatment was more common in those living in the urban, old age, nonsmoker and diabetes. Among the individuals who receiving medication treatment, controlled hypertension were less common in those living in the urban, young age, low education attainment, overweight and obese. Despite high rate of hypertension, awareness, treatment and control of hypertension still need to be strengthened.

Project description:ObjectivesHypertension has been established as a major public health problem in Africa, but its specific contributions to disease burden are still incompletely understood. We report the prevalence and determinants of hypertension, detection, treatment and control rates among adults in major cities in Cameroon.DesignCross-sectional study.SettingsCommunity-based multicentre study in major cities in Cameroon.ParticipantsParticipants were self-selected urban dwellers from the Center, Littoral, North-West and West Regions, who attended on 17 May 2011 a screening campaign advertised through mass media. PRIMARY AND SECONDARY OUTCOMES MEASURES: Hypertension defined as systolic (and/or diastolic) blood pressure (BP)??140 (90) mm Hg, or ongoing BP-lowering medications.ResultsIn all, 2120 participants (1003 women) were included. Among them, 1007 (prevalence rate 47.5%) had hypertension, including 319 (awareness rate 31.7%) who were aware of their status. The prevalence of hypertension increased with age overall and by sex and region. Among aware hypertensive participants, 191 (treatment rate 59.9%) were on regular BP-lowering medication, and among those treated, 47 (controlled rate 24.6%) were at target BP levels (ie, systolic (and diastolic) BP<140 (90) mm Hg). In multivariable logistic regression analysis, male gender, advanced age, parental history of hypertension, diabetes mellitus, elevated waist and elevated body mass index (BMI) were the significant predictors of hypertension. Likewise, male gender, high BMI and physical inactivity were associated with poor control.ConclusionsHigh prevalence of hypertension with low awareness, treatment and control were found in this urban population; these findings are significant and alarming with consideration to the various improvements in the access to healthcare and the continuing efforts to educate communities over the last few decades.

Project description:ObjectivesLiterature suggested that multi-ethnic Western populations experienced differential hypertension outcomes, but evidence is limited in Asia. This study was aimed to determine sociodemographic correlates of hypertension and its awareness, treatment and control among a multi-ethnic Asian population living in Singapore.SettingWe used cross-sectional data of participants from the Multi-Ethnic Cohort (MEC) (n=14 530) recruited in Singapore between 2004 and 2010.ParticipantsParticipants who completed questionnaire and attended health examination, without cardiovascular diseases, cancer, stroke, renal failure, asthma and mental illnesses were included in the study. Multivariable logistic regression models were used to determine sociodemographics factors associated with hypertension, unawareness of having hypertension, untreated and uncontrolled hypertension.ResultsAmong 10 215 participants (47.2% Chinese, 26.0% Malay and 26.8% Indian), hypertension prevalence was estimated to be 31.1%. Older age, Malay ethnicity, male, lower educational level and being homemaker or retired/unemployed were factors significantly associated with hypertension. Stratified analysis suggested that age and education were consistently associated with hypertension across all ethnic groups. The proportions of being unaware, untreated and uncontrolled were 49.0%, 25.2% and 62.4%, respectively. Ethnicity and younger age were associated with unawareness; younger age, male and lower educational level were associated with untreated hypertension and older age was associated with uncontrolled hypertension.ConclusionsIn this study, ethnic differences in relation to hypertension were associated with sociodemographic variability in ethnic groups. Age and educational level were consistent correlates of hypertension in all ethnic groups. Unawareness and uncontrolled hypertension were common in this Asian population and associated with sociodemographic factors. More targeted strategies may be required to overcome the observed disparities.

Project description:IntroductionSub-Saharan Africa is experiencing a surge in the burden of hypertension, and rural communities are increasingly affected by the epidemic.ObjectivesWe aimed to determine the prevalence of and factors associated with hypertension in rural communities of the Baham Health District (BHD), Cameroon. In addition, we sought to assess awareness, treatment and control rates of hypertension among community members.DesignA community-based cross-sectional study.SettingParticipants from five health areas in the BHD were recruited from August to October 2018.ParticipantsConsenting participants aged 18 years and above were included.ResultsWe included 526 participants in this study. The median age of the participants was 53.0 (IQR=35-65) years and 67.1% were female. The crude prevalence of hypertension was 40.9% (95% CI=36.7-45.1) with no gender disparity. The age-standardised prevalence of hypertension was 23.9% (95% CI=20.3-27.5). Five-year increase in age (adjusted OR (AOR)=1.34; 95% CI=1.23-1.44), family history of hypertension (AOR=2.22; 95% CI=1.37-3.60) and obesity (AOR=2.57; 95% CI=1.40-4.69) were associated with higher odds of hypertension after controlling for confounding. The rates of awareness, treatment and control of hypertension were 37.2% (95% CI=31.0-43.9), 20.9% (95% CI=16.0-26.9) and 22.2% (95% CI=12.2- 37.0), respectively.ConclusionThe high prevalence of hypertension in these rural communities is associated with contrastingly low awareness, treatment and control rates. Age, family history of hypertension and obesity are the major drivers of hypertension in this community. Veracious policies are needed to improve awareness, prevention, diagnosis, treatment and control of hypertension in these rural communities.

Project description:Objectives Previous studies reported that there were disparities in hypertension management among different ethnic groups, and this study aimed to systematically determine the prevalence, awareness, treatment, and control rates of hypertension in multiple Chinese ethnic groups. Methods We searched Embase, PubMed, and Web of Science for articles up to 25 October, 2022. The pooled prevalence, awareness, treatment, and control rates of hypertension were estimated with 95% confidence intervals (CI). The heterogeneity of estimates among studies was assessed by the Cochran Q test and I2 statistic. Meta-regression analyses were conducted to identify the factors influencing the heterogeneity of the pooled prevalence, awareness, treatment, and control rate of hypertension. Results In total, 45 publications including 193,788 cases and 587,826 subjects were eligible for the analyses. The lowest prevalence was found in the Han group (27.0%), and the highest prevalence was in the Mongolian population (39.8%). The awareness rates ranged from 24.4% to 58.0% in the four ethnic groups. Both the highest treatment and control rates were found in the Mongolian population (50.6% and 16.0%, respectively), whereas the Yi group had the lowest control rate (8.0%). In addition, the study year, the mean age of subjects, mean body mass index of subjects, tobacco use (%), alcohol use (%), residence (urban%), and education (primary school%) had varied effects on heterogeneity. Conclusions These findings highlight the disparities in prevalence, awareness, treatment, and control rates of hypertension in a different ethnic population of China, which could provide suggestions for making targeted prevention measures.

Project description:The prevalence of hypertension in Chinese Mainland has increased rapidly in the recent decades. This study aimed to determine the prevalence of hypertension and sodium intake in an economically booming area in China.9600 adults aged from 18 to 69 years old in Jiangsu Province of China were recruited using a complex, multistage sampling method. Blood pressure was measured and a face-to-face interview was conducted among all participants. 24 hours (24-h) urine sample was collected from each participant and then measured for sodium and potassium. Hypertension was determined by blood pressure and use of anti-hypertension medications. All of the analyses were weighted according to the population distribution in the province.Overall, the weighted means of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 128.8 mm Hg (95 % confidence interval, CI, 128.3-129.3) and 82.2 mm Hg (95 % CI, 81.4-83.1). The weighted hypertension prevalence of Jiangsu residents was 33.0 % (95 % CI, 29.4-36.7 %). Among those with hypertension, 31.4 % (95 % CI, 24.6-38.1) were aware of their blood pressure condition. In total, 88.4 % (95 % CI, 83.5-93.3) of those with known hypertension took anti-hypertension medications. Only 23.7 % (95 % CI, 13.3-34.2) of those under anti-hypertension medications had their blood pressure controlled. The mean of 24-h urinary sodium excretion was 188.2 mmol (standard deviation, SD, 69.5), representing that the mean intake of salt was 11.0 g (SD, 4.1) through conversion.Hypertension and excessive sodium intake in adults are prevalent in Jiangsu Province, China. These observations suggest that a public health approach is necessary to prevent hypertension and manage hypertensive patients.

Project description:The purpose of the present study was to describe the temporal trends in prevalence and management status of hypertension in Korea between 1998 and 2015. Data of adults who were aged 30 years or older were extracted from the Korea National Health and Nutrition Examination Survey, a nationwide representative population-based survey. Hypertension was prevalent in 30.5% of Korean adults. The age and sex standardized prevalence showed little change between 1998 and 2015. The elderly population and men showed higher prevalence. The rates of awareness, treatment, and control showed substantial improvements among hypertensive subjects between 1998 and the time period of 2007‒2009 (awareness, from 23.5 to 66.3%; treatment, from 20.4 to 60.3%; and control, from 4.9 to 42.1%), after which the numbers reached a plateau and no significant changes were observed subsequently (67.3%, 63.6%, and 46.2%, respectively, between 2013 and 2015). The management status remained poor especially among the young population and in men. In conclusion, the hypertension prevalence remained stable at approximately 30% in Korea between 1998 and 2015. While awareness, treatment, and control of hypertension improved remarkably, the young population and particularly men showed a suboptimal management status.

Project description:BACKGROUND AND OBJECTIVES:Despite being one of the leading risk factors of cardiovascular mortality, there are limited data on changes in hypertension burden and management from India. This study evaluates trend in the prevalence, awareness, treatment and control of hypertension in the urban and rural areas of India's National Capital Region (NCR). DESIGN AND SETTING:Two representative cross-sectional surveys were conducted in urban and rural areas (survey 1 (1991-1994); survey 2 (2010-2012)) of NCR using similar methodologies. PARTICIPANTS:A total of 3048 (mean age: 46.8±9.0 years; 52.3% women) and 2052 (mean age: 46.5±8.4 years; 54.2% women) subjects of urban areas and 2487 (mean age: 46.6±8.8 years; 57.0% women) and 1917 (mean age: 46.5±8.5 years; 51.3% women) subjects of rural areas were included in survey 1 and survey 2, respectively. PRIMARY AND SECONDARY OUTCOME MEASURES:Hypertension was defined as per Joint National Committee VII guidelines. Structured questionnaire was used to measure the awareness and treatment status of hypertension. A mean systolic blood pressure <140?mm Hg and diastolic blood pressure <90?mm Hg was defined as control of hypertension among the participants with hypertension. RESULTS:The age and sex standardised prevalence of hypertension increased from 23.0% to 42.2% (p<0.001) and 11.2% to 28.9% (p<0.001) in urban and rural NCR, respectively. In both surveys, those with high education, alcohol use, obesity and high fasting blood glucose were at a higher risk for hypertension. However, the change in hypertension prevalence between the surveys was independent of these risk factors (adjusted OR (95%?CI): urban (2.3 (2.0 to 2.7)) rural (3.1 (2.4 to 4.0))). Overall, there was no improvement in awareness, treatment and control rates of hypertension in the population. CONCLUSION:There was marked increase in prevalence of hypertension over two decades with no improvement in management.
