A cross-sectional study of the prevalence, awareness, treatment and control of hypertension in Shenzhen, China.

ABSTRACT:

Objectives

An 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.

Methods

A 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.

Results

We 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.

Conclusions

Our 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:ObjectiveHypertension (HTN) is an important public health issue worldwide, associated with the rapid economic development and urbanisation over the last decades. This is especially the case in Shenzhen, which has benefited greatly from the reform and opening-up policies. However, there is limited information on the epidemiology of HTN in this region. This study was designed to investigate the prevalence, awareness, treatment and control of HTN and the associated factors among adult residents in Shenzhen, China.DesignPopulation-based, cross-sectional study.ParticipantsThrough the multistage stratified random sampling method, a representative sample of 10 043 urban population aged ≥18 years were selected. Three consecutive blood pressure (BP) readings were measured after resting for a 5 min seat by trained staff and HTN was defined as mean systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or self-reported current use of antihypertensive drugs. Participants were interviewed using a structured questionnaire. Anthropometric details, BP, blood and urine samples were also collected.Primary outcome measurePrevalence of HTN.ResultsOverall, the weighted prevalence of HTN among residents in Shenzhen was 19.2% (95% CI 18.5 to 20.0). Among patients with HTN, 55.0% (95% CI 52.9 to 57.1) were aware of their condition and 44.9% (95% CI 42.8 to 47.1) were taking antihypertensive medications, but only 21.7% (95% CI 20.0 to 23.5) achieved BP control. Among those who knew their HTN, 81.7% (95% CI 79.3 to 83.8) were under treatment and 48.3% (95% CI 45.1 to 51.5) were controlled among those with treated HTN. Male, older age, lower educational level, overweight and obesity, family history of HTN, tobacco smoking, alcohol intake, diabetes mellitus, dyslipidaemia and high uric acid were associated with HTN.ConclusionsHTN is a major public health concern in Shenzhen, which has low awareness, treatment and control rates, and is associated with several risk factors. Effective multifaceted implementation strategies are highly needed to combat the emerging burden of HTN.

Project description:ObjectiveHypertension has become the leading cause of death worldwide. Data on hypertension management among Shenzhen elderly are sparse. Our study aims to investigate treated and controlled hypertension in Shenzhen elderly, and identify relevant predictors.DesignA cross-sectional study.SettingCommunities in Shenzhen, Guangdong, China.ParticipantsA cross-sectional study was conducted. We employed a convenience sampling method to select participants; 124 007 participants aged 65 years and older were recruited from January to December 2018 at local community health centres in Shenzhen.Main outcome measuresData on treatment, control and influencing factors of hypertension were obtained from a standard questionnaire, physical measurements and biochemical analyses.ResultsPrevalence of hypertension was 55.8% among the sample population. Among this group of hypertensive patients, those undergoing hypertension treatment and those with hypertension under control were 54.4% and 32.3%, respectively. Employing multivariate analysis, significant associations were found between treatment and older age, junior high school education and above (OR=1.25, p＜0.05), being widowed rather than being married or cohabiting (OR=1.28, p＜0.05), engaging in physical activity (OR=1.14, p＜0.05), ex-smoker (OR=1.19, p＜0.05), habitual drinker (OR=0.72, p＜0.05), history of cardiovascular disease (CVD) (OR=2.20, p＜0.05) and comorbidities, with a higher probability for those with obesity (OR=1.89, p＜0.05), central obesity (OR=1.10, p＜0.05), diabetes (OR=1.49, p＜0.05) or dyslipidaemia (OR=1.20, p＜0.05). Male sex (OR=0.91, p＜0.05), junior high school education and above (OR=1.28, p＜0.05), engaging in physical activity (OR=1.06, p＜0.05), history of CVD (OR=1.82, p＜0.05) and individuals who had diabetes (OR=1.52, p＜0.05) or dyslipidaemia (OR=1.05, p＜0.05) were associated with increased likelihood of control. Aged 80 years and older (OR=0.93, p＜0.05), habitual drinker (OR=0.73, p＜0.05) and central obesity (OR=0.94, p＜0.05) were negatively associated with control of hypertension.ConclusionsWe found a high prevalence of hypertension, but a low prevalence of treatment and control among Shenzhen elderly.

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:BACKGROUND:In China, the local health insurance coverage is usually related to timely reimbursement of hypertensive care in primary care settings, while health insurance that is not local could represent an obstacle for accessibility and affordability of primary care for hypertensive patients. OBJECTIVE:To investigate whether local health insurance schemes have a positive impact on hypertension management and control. DESIGN:We performed an on-site, face-to-face, patients survey in community health centres (CHCs) in Shenzhen, China. SETTING AND PARTICIPANTS:Hypertensive patients seeking healthcare from CHCs were selected as study participants using a systematic sampling design. MAIN MEASURES:We obtained information about insurance status, social capital, drug treatment and control of hypertension. Multivariable stepwise logistic regression models were constructed to test the associations between insurance status and hypertension management, as well as insurance status and social capital. RESULTS:A total of 867 participants were included in the final study analysis. We found that the participants covered by local insurance schemes were more likely to be managed in primary care facilities (61.1% vs 81.9%; OR=2.58, 95% CI: 1.56 to 4.28), taking antihypertensive drugs (77.2% vs 88.0%; OR=2.23, 95% CI: 1.37 to 3.62) and controlling blood pressure (43.0% vs 52.4%; OR=1.46, 95% CI: 1.03 to 2.07) when compared with those with insurance coverage that is not local. The participants covered by local insurance schemes reported a higher score of perceived generalised trust than those without (4.23 vs 3.97; OR=0.74, 95% CI: 0.53 to 0.86). CONCLUSION:Our study demonstrates that local health insurance coverage could help improve management and control of hypertension in a primary care setting. Policymakers suggest initiating social interventions for better management and control of hypertension at the primary care level, although the causal pathways across insurance status, social capital and control of hypertension deserve further investigations.
