Factors Associated With Treatment and Control of Hypertension in a Healthy Elderly Population Free of Cardiovascular Disease: A Cross-sectional Study.

ABSTRACT:

Background

Despite readily available treatments, control of blood pressure (BP) with population aging remains suboptimal. Further, there are gaps in the understanding of the management of high BP in the aged. We explored antihypertensive treatment and control among elderly hypertensive participants free from overt cardiovascular disease (CVD), and identified factors related to both "untreated" and "treated but uncontrolled" high BP.

Methods

We analyzed baseline data from 19,114 individuals aged ≥65 years enrolled from Australia and United States (US) in the ASPirin in Reducing Events in the Elderly study. Hypertension was defined as an average systolic/diastolic BP ≥140/90 mm Hg and/or the use of any BP lowering medication. "Controlled hypertension" was defined if participants were receiving antihypertensive medication and BP <140 and 90 mm Hg. Descriptive analyses were used to summarize hypertension control rates; logistic regression was used to investigate relationships with treatment and BP control.

Results

Overall, 74% (14,213/19,114) of participants were hypertensive; and of these 29% (4,151/14,213) were untreated. Among those treated participants, 53% (5,330/10,062) had BP ≥140/90 mm Hg. Participants who were untreated were more likely to be men, have higher educational status, and be in good physical health, and less likely to have significant comorbidities. The factors related to "treated but uncontrolled" BP included older age, male, Black race (vs. White), using antihypertensive monotherapy (vs. multiple) and residing in Australia (vs. US).

Conclusions

High levels of "untreated" and "treated but uncontrolled" BP occur in healthy elderly people without CVD, suggesting there are opportunities for better BP control in the primary prevention of CVD in this population.

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:BACKGROUND:Hypertension is a rapidly growing epidemic in China. Yet, it remains inadequately controlled, especially in rural areas. The internet has shown potential for better health management in different settings; however, few studies have investigated its role in hypertension management in China. OBJECTIVE:This study aims to examine the association between internet access and hypertension awareness, treatment, and control among elderly Chinese adults and to investigate whether the association between internet access and hypertension management differed between those living in urban and rural areas. METHODS:We obtained data from the nationally representative survey of the China Health and Retirement Longitudinal Study in 2011. Hypertension was defined as (1) average systolic blood pressure of ≥140 mm Hg or average diastolic blood pressure of ≥90 mm Hg or (2) currently taking antihypertensive medications. The outcome assessed included hypertension awareness, treatment, and control. The key independent variable was defined as whether one had internet access at home. We performed multivariate logistic regressions for each of the 3 outcomes. RESULTS:Among 5135 hypertensive respondents (age 62.4 [SD 9.9] years; 2351/5135, 45.78% men), 12.89% (662/5135) had internet access at home. Compared with those who had no internet access, internet access was positively associated with hypertension awareness (odds ratio [OR] 1.36, 95% CI 1.07-1.73) and treatment (OR 1.38, 95% CI 1.09-1.75), but not with control (OR 1.19, 95% CI 0.90-1.58). Internet access reduced urban-rural disparity in hypertension awareness by 9.6% (P=.02), treatment by 8.3% (P=.05), but not in control. In addition, the moderating effect of internet access on urban-rural disparities in hypertension management was larger among females. The decreased urban-rural disparities were primarily driven by that internet access improved the management level in rural areas. CONCLUSIONS:Despite the low rate of internet access among the elderly population, the internet shows its potential as a platform for achieving better hypertension management in China. Strategies for reducing the disparities in hypertension management and overall disease burden of hypertension among the elderly population might consider the internet as a platform.

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.
