Project description:ObjectiveAs the most important risk factors of cardiovascular disease, pre-hypertension and hypertension are important public health challenges. Few studies have focused on the trends of pre-hypertension and hypertension specifically for the aging population in China. Given the anticipated growth of the elderly population in China, there is an urgent need to document the conditions of pre-hypertension and hypertension in this aging population.MethodsWe conducted two cross-sectional surveys of Chinese adults aged ≥60 years in 2001 and 2010. A total of 2,272 (943 males, 1,329 females) and 2,074 (839 males, 1,235 females) participants were included in the two surveys, respectively.ResultsThe age- and sex-standardized prevalence of hypertension significantly increased from 60.1% to 65.2% from the 2001 to the 2010 survey. Among the participants with hypertension, the awareness, treatment and control of hypertension all significantly increased from 69.8% to 74.5%, 50.3% to 63.7%, and 15.3% to 30.3%, respectively, from 2001 to 2010. A logistic regression showed that a higher education level, a higher BMI, a family history of hypertension and doctor-diagnosed cardiovascular disease were significantly associated with hypertension awareness and treatment.ConclusionHypertension prevalence increased rapidly between the years surveyed. Although the awareness, treatment and control of hypertension improved significantly, the values of these variables remained low. More attention should be given to the elderly because the population is aging worldwide, and urgent action, optimal treatment approaches and proper public health strategies must be taken to prevent and manage hypertension.

Project description:IntroductionAs part of the Centers for Medicare and Medicaid Innovation Practice Transformation Network, an integrated healthcare system implemented a multimodal, population health-based hypertension clinical pathway program (HCPP) focused on hypertension management.AimTo determine whether the HCPP was associated with changes in hypertension control or process-of-care measures and whether associations varied for sites serving higher versus lower proportions of historically underserved patients.SettingAn integrated academic health system encompassing 5 clinic networks and 85 primary and specialty care sites.Program descriptionThe HCPP was implemented at some sites (adopters) but not others (non-adopters) and had four components: (1) stakeholder engagement; (2) clinical staff retraining; (3) electronic health record-based prompts; and (4) performance monitoring and feedback. Program goals were to encourage clinical teams to increase the frequency of follow up visits and adopt standardized approaches to blood pressure (BP) measurements and antihypertensive medication regimen advancement defined as adding or titrating existing medication.Program evaluationThis quasi-experimental study used 2017-2019 data from 63,497 patients with hypertension and multivariable difference-in-differences analyses to evaluate changes in outcomes at 19 adopter versus 39 non-adopter sites before and after HCPP implementation. Adoption was associated with 3.5 times differentially greater odds of a BP reassessment (OR 3.5, 95% CI 3.3-3.8), 11% differentially greater odds of BP control (BP<140/90 mmHg) (OR 1.11, 95% CI 1.07-1.15), and 12% differentially greater odds of having non-severely elevated BP (systolic BP < 155 mmHg) (OR 1.12, 95% CI 1.05-1.19). HCPP adoption was not associated with differential changes in 90-day follow-up BP measurement. Adoption was associated with 23% differentially greater odds of appropriate medication advancement (OR 1.23, 95% CI 1.04-1.46). A similar pattern was observed when limiting comparisons to sites caring for a higher proportion of historically underserved populations.DiscussionA multimodal population health approach to transforming hypertension care was associated with improved BP outcomes.

Project description:ObjectivesCell entry of SARS-CoV-2 depends on angiotensin-converting enzyme II. Angiotensin-converting enzyme II is homologous with, but acts antagonistically to, angiotensin-converting enzyme and has the critical function of protecting the lungs. Angiotensin-converting enzyme inhibitors are major antihypertensive agents. Thus, we aimed to analyze the impact of the prevalence of preexisting hypertension on the local spread of COVID-19.MethodsData on SARS-CoV-2 infection and the estimated number of patients who received medical treatment on the basis of disease classification using the International Statistical Classification of Diseases and Related Health Problems (10th Revision) in each prefecture were obtained from the official Japanese notifications database. We analyzed the association between the proportion of patients with each disease and SARS-CoV-2-infection prevalence.ResultsThe ratio of patients treated for diseases of the circulatory system, especially hypertensive disorders, per population demonstrated the most significant negative correlation with SARS-CoV-2-infection prevalence (Spearman's rank correlation, P < 0.01). Age group analysis revealed a significant negative correlation in age groups 35-44, 45-54, 55-64, 75-84, and ≥85.ConclusionsOur findings suggest that hypertension treatment may play a protective role against the local spread of SARS-CoV-2 infection.

Project description:IntroductionChronic kidney disease (CKD) is often associated with poor hypertension control and treatment resistance, but whether CKD modifies the effect of hypertension control on outcomes is unknown.MethodsWe studied 10-year mortality and cardiovascular events according to hypertension control status and CKD (glomerular filtration rate <60 ml/min/1.73m2) in 4262 community-dwelling individuals (40% men) more than 65 years of age.ResultsAt baseline, 19% had CKD, and 31.2% had controlled hypertension on ≤3 antihypertensive drugs, 62.3% uncontrolled hypertension ≥140/90 mm Hg on ≤2 drugs, and 6.5% apparent treatment-resistant hypertension (aTRH) ≥140/90 mm Hg with ≥3 drugs or use of ≥4 drugs regardless of level. There were 1115 deaths (305 total cardiovascular deaths) and 274 incident nonfatal or fatal strokes or coronary events. Compared to the reference group (controlled hypertension and no CKD), participants without CKD and with uncontrolled hypertension or aTRH had adjusted hazard ratios for all-cause mortality of 0.86 (0.74-1.01) and 1.09 (0.82-1.46), and those with CKD and controlled or uncontrolled hypertension, or aTRH, of 1.33 (1.06-1.68), 1.14 (0.93-1.39), and 1.34 (0.98-1.85), respectively. Participants with aTRH and CKD had a risk of coronary death more than 3 times higher than that of the reference group; participants with aTHR, with or without CKD, had a risk of stroke more than twice as high, and those with CKD but controlled hypertension a 2 times higher risk for cardiovascular deaths from other causes.DiscussionCKD does not appear to amplify the risk of stroke and coronary events associated with aTRH in this older population. The reasons for excess cardiovascular mortality from other causes associated with controlled hypertension require further study.

Project description:In patients with type 2 diabetes, the prevalence of hypertension is higher than in non-diabetic subjects. Despite the high cardiovascular risk involving hypertension in these patients, its prevalence and control are not well known. The aims of this study were: to estimate the hypertension prevalence, awareness, treatment and control in Spanish adults with type 2 diabetes attended in Primary Care; and to analyse its time trend from 2003 to 2009. A serial cross-sectional study from 2003 to 2009 was performed in 21 Primary Care Centres in Madrid. The study population comprised all patients with diagnosed type 2 diabetes in their computerised medical history. Overall annual prevalence during the period 2003-2009 was calculated from and according to sex and age groups. Linear trend tests, regression lines and coefficients of determination were used. In 2003 89.78% (CI 87.92-91.64) of patients with type 2 diabetes suffered hypertension and 94.76% (CI: 92.85-96.67) in 2009. This percentage was greater for women and for patients over 65 years old. 30% of patients suffered previously undiagnosed hypertension in 2003 and 23.1% in 2009. 97% of diagnosed patients received pharmacological treatment and 28.79% reached the blood pressure objective in 2009. The average number of antihypertensive drugs taken was 2.72 in 2003 and 3.27 in 2009. Only 5.2% of patients with type 2 diabetes show blood pressure levels below 130/80 mmHg. Although significant improvements have been achieved in the diagnosis and control of hypertension in people with type 2 diabetes, these continue to remain far from optimum.

Project description:Cross-sectional epidemiological studies suggested the intake of fish and seafood was negatively associated with the prevalence of frailty. This study aimed to investigate the hypothesis that the prevalence of frailty is negatively associated with the consumption of total seafood and fish at baseline and 4-year follow-up. Using a multicenter longitudinal study of community-dwelling Korean adults aged 70-84 years old, 953 participants at baseline and 623 participants at 4-year follow-up were included after excluding participants without data on frailty or dietary intake in the Korean Frailty and Aging Cohort Study. Frailty was defined using the Cardiovascular Health Study index, and participants with scores ≥3 were considered frail. The trained dietitians obtained two non-consecutive 24-h dietary recalls during spring and fall at baseline. The prevalence of frailty was 13.5%. The intake of fish (OR 0.47; 95% CI 0.24-0.91; p for trend = 0.028) and total seafood (OR 0.34; 95% CI 0.18-0.68; p for trend = 0.002) at baseline was associated with frailty at 4-year follow-up after adjusting for the confounding factors. The intake of fish and total seafood at the baseline was negatively associated with the prevalence of exhaustion, low handgrip strength, and slow gait speed at 4-year follow-up. However, shellfish intake was not associated with frailty. In addition, the intake of fish, shellfish, and total seafood did not differ among the frailty transition groups in terms of deterioration, persistence, and reversal. The total consumption of seafood, particularly fish, could be beneficial for preventing frailty in Korean community-dwelling older adults. In particular, the consumption of fish (total seafood) at baseline could be beneficial for preventing exhaustion, low handgrip strength, and slow gait speed at 4-year follow-up.

Project description:BackgroundThe relationship between subjective cognitive decline and frailty, two components of the so-called reversible cognitive frailty, in the elderly remains unclear. This study aims to elucidate whether this association exists, independent of confounding factors such as nutritional status, kidney function, inflammation, and insulin resistance.Methods2386 participants (? 65 years of age) selected from the Healthy Aging Longitudinal Study in Taiwan (HALST) study. Fried frailty phenotype was adopted to quantify frailty status. We classified cognitive status into two categories-subjective cognitive decline (SCD), and normal cognition-and used polytomous logistic regressions to investigate the associations between SCD and frailty.ResultsThere were 188 (7.88%), 1228 (51.47%), and 970 (40.65%) participants with frailty, pre-frailty, and robustness, respectively. Compared to those with normal cognition, elders with SCD were more likely to have pre-frailty (odds ratio [OR]: 1.36, 95% confidence interval [CI]: 1.10-1.67, p = 0.004) or frailty (OR: 1.78, 95% CI: 1.23-2.58, p = 0.002) after adjusting for age, gender, education level, comorbidity, nutritional status, kidney function, and biochemical-related factors.ConclusionsA significant association between subjective cognitive decline and frailty was revealed in this study. Subjective cognitive decline was positively associated with pre-frailty or frailty even after adjusting for potential confounding factors. Our results can provide useful references in understanding mechanisms and developing suitable preventive strategies for the elderly with reversible cognitive frailty.

Project description:BackgroundFrailty and sarcopenia are prevalent in chronic kidney disease (CKD) populations and could increase the risk for adverse health outcomes. Few studies assess the correlation between frailty, sarcopenia and CKD in non-dialysis patients. Therefore, this study aimed to determine frailty-associated factors in elderly CKD stage I-IV patients, expected to early identify and intervene in the frailty of elderly CKD patients.MethodsA total of 774 elderly CKD I-IV patients (>60 years of age) recruited from 29 clinical centers in China between March 2017 and September 2019 were included in this study. We established a Frailty Index (FI) model to evaluate frailty risk and verified the distributional property of FI in the study population. Sarcopenia was defined according to the criteria of the Asian Working Group for Sarcopenia 2019. Multinomial logistic regression analysis was used to assess the associated factors for frailty.ResultsSeven hundred seventy-four patients (median age 67 years, 66.0% males) were included in this analysis, with a median estimated glomerular filtration rate of 52.8 mL/min/1.73 m2 . The prevalence of sarcopenia was 30.6%. The FI exhibited a right-skewed distribution. The age-related slope of FI was 1.4% per year on a logarithmic scale (r2 = 0.706, 95% CI 0.9, 1.8, P < 0.001). The upper limit of FI was around 0.43. The FI was related to mortality (HR = 1.06, 95% CI 1.00, 1.12, P = 0.041). Multivariate multinomial logistic regression analysis showed that sarcopenia, advanced age, CKD stage II-IV, low level of serum albumin and increased waist-hip ratio were significantly associated with high FI status, while advanced age and CKD stage III-IV were significantly associated with for median FI status. Moreover, the results from the subgroup were consistent with the leading results.ConclusionsSarcopenia was independently associated with an increased risk for frailty in elderly CKD I-IV patients. Patients with sarcopenia, advanced age, high CKD stage, high waist-hip ratio and low serum albumin level should be assessed for frailty.

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:We aimed to examine whether hypertension status modified the association between sleep duration and stroke among middle-aged and elderly population. This cross-sectional study included 10 516 participants aged ≥45 years from the China Hypertension Survey study. Sleep duration and history of stroke were assessed by questionnaires. Multivariate logistic regression analyses, a generalized additive model (GAM) and smooth curve fitting (penalized spline method) and a two-piecewise logistic regression models were performed to evaluate the association between sleep duration and stroke in different status of hypertension. 95% confidence interval (CI) for turning point was obtained by bootstrapping. Multiple logistic analyses showed that per 1 hour increase in sleep duration was associated with a 37% increased prevalence of stroke among participants without hypertension and associated with a 8% increased prevalence of stroke among hypertensive participants (without hypertension: odds ratio [OR] = 1.37, 95% CI 1.09-1.71; with hypertension: OR = 1.08, 95% CI 0.95-1.21; PInteraction = .029). The fully adjusted smooth curves presented a linear association between sleep duration and stroke among participants without hypertension, but a threshold, nonlinear association among hypertensive participants. The turning point for the curve was found at a sleep duration of 8 (95% CI 5-9) h among hypertensive patients. The ORs (95% CIs) for stroke were 0.92 (0.79, 1.06) and 1.60 (1.23, 2.08) to the left and right of the turning point, respectively. In conclusion, we found a linear association between sleep duration and stroke among middle-aged and elderly participants without hypertension, but a threshold, nonlinear association among hypertensive participants.
