Hypertensive Patients In China Research Articles

Association of the metabolic score for insulin resistance with cardiovascular diseases, cardiovascular and all-cause mortality in Chinese hypertensive population.

Little is known about the relationship between the metabolic score for insulin resistance (METS-IR) and the prognosis of hypertensive patients in China. To investigate the association between the novel non-insulin-based METS-IR index and the cardiovascular composite endpoints and all-cause mortality in Chinese hypertensive participants. This cohort study used data from the China H-Type Hypertension Project, a long-term prospective cohort consisting of 14234 hypertensive patients in southern China, with a baseline from March to August 2018. The median follow-up period for participants was 3.94 years, as of 2022. The data analysis period is from July 2023 to September 2023. METS-IR index of participants in the Chinese H-type hypertension project. The calculation formula for METS-IR is (Ln (2 × FPG) +TG) × BMI/Ln (HDL-C). Cardiovascular events and cardiovascular, all-cause mortality were identified by linking the cohort database with the health care system through October, 2023. A total of 14220 participants were included in this study. The prevalence rates of cardiovascular disease (CVD), cardiovascular death, and all-cause death were 2.59% (369/14220), 2.79% (397/14220), and 5.66% (805/14220), respectively. After adjusting for confounding factors in the multivariate logistic regression analysis models, the METS-IR index was significantly positively correlated with CVD, and cardiovascular, all-cause mortality, whether as a categorical or continuous variable. Layered analysis showed that the METS-IR index of hypertensive participants in different subgroups was positively correlated with the endpoint event. This large, prospective cohort study demonstrated that the METS-IR index, a new IR evaluation index, were independently associated with a higher risk of the cardiovascular composite endpoint and all-cause mortality among Chinese hypertensive population. Importantly, our finding provides an independent indicator for evaluating the prognosis of hypertensive patients.

Home Blood Pressure Monitoring and Its Association With Blood Pressure Control Among Hypertensive Patients With High Cardiovascular Risk in China.

Home blood pressure monitoring (HBPM) is viewed as a facilitating factor in the initial diagnosis and long-term management of treated hypertension. However, evidence remains scarce about the effectiveness of HBPM use in the real world. This study aimed to examine the associations of HBPM use with blood pressure (BP) control and medication adherence. This prospective cohort study included hypertensive patients with high cardiovascular risk who were aged ≥50 years. At baseline, information about types of BP monitor, frequency of HBPM, perception of anti-hypertensive treatment, and measured office BP were collected. During the 1-year follow-up (visits at 1, 2, 3, 6, and 12 months), information on medication adherence was collected at each visit. The 2 major outcomes were BP control at baseline and medication adherence during the 1-year follow-up. A log-binomial regression model was used to examine the association between frequency of HBPM and outcomes, stratified by the perceptions of anti-hypertensive treatment. A total of 5,363 hypertensive patients were included in the analysis. The age was (64.6 ± 7.2) years, and 41.2% (2,208) were female. Of the total patients, 85.9% (4,606) had a home BP monitor and 47.8% (2,564) had an incorrect perception of anti-hypertensive treatment. Overall, 24.2% (1,299) of patients monitored their BP daily, 37.6% (2,015) weekly, 17.3% (926) monthly, and 20.9% (1,123) less than monthly. At baseline, the systolic BP and diastolic BP were (146.6 ± 10.8) mmHg and (81.9 ± 10.6) mmHg, respectively, and 28.5% (1,527) of patients had their BP controlled. Regardless of whether the patients had correct or incorrect perceptions of anti-hypertensive treatment, there is no significant association between HBPM frequency and BP control at baseline. During the 1-year follow-up, 23.9% (1,280) of patients had non-adherence to medications at least once. In patients with an incorrect perception of anti-hypertensive treatment, those monitoring BP most frequently (daily) had the highest non-adherence rate (29.9%, 175/585). Compared with those monitoring their BP less than monthly, patients who monitored their BP daily were more likely not to adhere to anti-hypertensive medications (adjusted relative risk = 1.38, 95% confidence interval: 1.11-1.72, P = 0.004). HBPM performance among hypertensive patients in China is, in general, sub-optimal. No association was observed between using HBPM alone and hypertension control, indicating that the effects of HBPM could be conditional. Patients' misconceptions about anti-hypertensive treatment may impair the role of BP monitoring in achieving medication adherence. Fully incorporating the correct perception of hypertension into the management of hypertensive patients is needed.

Research on the control rate of hypertension under family physician-contracted service

BackgroundHypertension is one of the global public health problems. Family physician-contracted service (FPCS) is widely used in the health management of hypertension patients in China. The purpose of this study was to assess the effect of FPCS on hypertension control.MethodsPubMed, Web of Science, the Cochrane Library, China National Knowledge Network, Chinese Scientific and Technological Journal Database (CQVIP), and Wanfang Database were searched for randomized controlled trials related to family physician-contracted service and hypertension control effect, and meta-analysis was performed on the literature meeting the inclusion criteria. The source of heterogeneity was discovered by meta-regression, and it was further investigated by subgroup analysis. The risk difference (RD) and 95% confidence interval (CI) were utilized as effect values. Evaluations of publication bias and sensitivity analysis were also conducted.ResultsA total of 46 studies were included, and the pooled RD suggested that FPCS could effectively improve the control rate by 19% (RD = 0.19; 95%CI: 0.16–0.21; P < 0.001; I2 = 59.3%). The average age (β = 0.28; P = 0.05) and the intervention mode (β = 0.36; P < 0.001) were found to be heterogeneous sources by the meta-regression. According to subgroup analysis, the hypertension control rates of the elderly and working-age population in the experimental group were 93.6% and 90.1%, respectively; the control rates of the “family physician” mode (FP), “family physician + patient” mode (FPP) and “family physician + patient + family member” mode (FPPF) in the experimental group were 90.1%, 94.4%, and 92.6%, respectively. The sensitivity analysis revealed steady results, with no discernible publication bias.ConclusionsThe FPCS is beneficial to the control of hypertension. The control effect is influenced by average age and intervention mode. The control effect of hypertension in the elderly is better than that in the working-age population, and FPP and FPPF are more beneficial to the management of hypertension than FP. The quality and continuity of FPCS should receive more focus in the future, patient self-management and family support are also essential for managing hypertension.

Adherence Behaviors and Related Factors Among Elderly Hypertensive Patients in China: Evidence from the China Health and Retirement Longitudinal Study.

Non-adherence or partial adherence is the main reason for poor therapeutic effect of hypertension. This paper aims to assess adherence behaviors and related factors among elderly hypertensive patients in China. Participants aged ≥60 years, with hypertension, and with complete data in 2018 interviews of the China Health and Retirement Longitudinal Study (CHARLS) were included. The adherence behaviors included medication, blood pressure monitoring and the combined adherence behaviors. Referring to the social-ecological theory, correlates of adherence behaviors were divided into three layers, namely demographic characteristics, health behaviors, living environment and retirement. Univariate and multivariable logistic regression models were performed to identify factors of adherence behaviors. The prevalence of medication adherence (76.58%) was higher than that of blood pressure monitoring adherence (20.08%), and the full adherence rate was 18.53%. Self-rated health status, smoking status, living area, and health education status were detected to be associated with medication adherence and blood pressure monitoring adherence (all p < 0.05). Gender, sleep duration, health examination, and physical exercise were also detected to be associated with blood pressure monitoring adherence (all p < 0.05). Self-rated health status and health education status were detected to be associated with partially and fully adherence, while age, living area, and life satisfaction were detected to be associated with partially adherence, smoking status, sleep duration, health examination, and pension reliance were detected to be associated with fully adherence (all p < 0.05). Our study reveals the poor adherence behaviors of elderly hypertensive patients in China. This is most evident among those who were male, 60-69 years old, living in rural areas, self-reported being healthier, those without health examination and health education. Targeting these vulnerable populations, we suggest to strengthen health education, increase the publicity of basic public health services and enhance the self-management ability of hypertensive patients.

Acceptance of COVID-19 boosters among hypertensive patients in China: A multicenter cross-sectional study

ABSTRACT Hypertension, a prevalent chronic disease, has been associated with increased COVID-19 severity. To promote the COVID-19 booster vaccination of hypertensive patients, this study investigated the willingness to receive boosters and the related influencing factors based on the health belief model (HBM model). Between June and October 2022, 453 valid questionnaires were collected across three Chinese cities. The willingness to receive a booster vaccination was 72.2%. The main factors that influenced the willingness of patients with hypertension to receive a booster shot were male (χ2 = 7.008, p = .008), residence in rural (χ2 = 4.778, p = .029), being in employment (χ2 = 7.232, p = .007), taking no or less antihypertensive medication (χ2 = 9.372, p = .025), with less hypertension-related comorbidities (χ2 = 35.888, p < .0001), and did not have any other chronic diseases (χ2 = 28.476, p < .0001). Amid the evolving COVID-19 landscape, the willingness to receive annual booster vaccination was 59.4%, and employment status (χ2 = 10.058, p = .002), and presence of other chronic diseases (χ2 = 14.256, p < .0001) are associated with the willingness of annual booster vaccination. Respondents with higher perceived severity, perceived benefits, perceived self-efficacy, and lower perceived barriers were more willing to receive booster shots. The mean and median value of willingness to pay (WTP) for a dose of booster were 53.17 CNY and 28.31 CNY. Concerns regarding booster safety and the need for professional advice were prevalent. Our findings highlight the importance of promoting booster safety knowledge and health-related management among hypertensive individuals through professional organizations and medical specialists.

Study on the associations of meeting intensive systolic blood pressure control goals with risk for incident cardiovascular and cerebrovascular diseases among the adult hypertensive patients in China

Objective: To evaluate the associations of meeting intensive systolic blood pressure (SBP) control goals with risk for incident cardiovascular and cerebrovascular diseases among the adult hypertensive patients in China. Methods: We used data from adult hypertensive patients from the China Kadoorie Biobank. logistic regression models evaluated the influencing factors of meeting intensive and standard SBP control goals. Cox proportional hazard models evaluated the associations between meeting intensive vs. standard SBP control goals and risk for incident cardiovascular and cerebrovascular diseases. Results: A total of 3 628 hypertensive patients who reported continuous medication use were included in this study, of which 5.0% of the participants met the goals of intensive SBP control (≤130 mmHg). Participants with higher educational attainment (OR=2.36,95%CI: 1.32-4.04), healthier diet (OR=2.09,95%CI: 1.45-2.96), daily intake of fresh fruit (OR=1.67,95%CI: 1.17-2.36) and combination treatment (OR=1.82,95%CI: 1.03-3.09) were more likely to meet intensive SBP control goal after adjustment of age, sex and urban/rural areas. During an average follow-up of (10.0±3.7) years, 1 278 cases of composite cardiovascular outcome were recorded. This study did not find a statistical correlation between achieving the goal of enhanced SBP control and the occurrence of composite cardiovascular and cerebrovascular outcomes (HR=0.89, 95%CI: 0.63-1.25). For major adverse cardiovascular events (MACE), cerebrovascular diseases, stroke, and ischemic stroke, we observed a trend of decrease in risk of outcomes with more intensive SBP control (trend test P<0.05). Conclusions: We observed decreased risk for MACE and cerebrovascular diseases with more intensive SBP control. However, there was no significant risk reduction for cardiovascular and cerebrovascular diseases when meeting the intensive SBP control goal, compared to the standard SBP control goal.

Relationship between self-care compliance, trust, and satisfaction among hypertensive patients in China.

Hypertension is a growing public health concern worldwide. It is a leading risk factor for all-cause mortality and may lead to complications such as cardiovascular disease, stroke, and kidney failure. Poor compliance of hypertensive patients is one of the major barriers to controlling high blood pressure. Compliance is not ideal among Chinese patients, and increasing patient self-care compliance with hypertension is necessary. This article analyzes the status of self-care compliance, trust, and satisfaction among Chinese hypertensive patients using cross-sectional data from Zhejiang Province. We use a multi-group structural equation model (MGSEM) to compare the interrelationships across genders. The study's findings show that the average trust, satisfaction, and compliance scores are 3.92 ± 0.55, 3.98 ± 0.61, and 3.33 ± 0.41, respectively. Female patients exhibit higher average total scores for trust and compliance than male patients. The SEM results indicate that trust has a direct positive association with compliance [β = 0.242, 95% CI: (0.068, 0.402)] and satisfaction [β = 0.260, 95% CI: (0.145, 0.367)], while their satisfaction is not directly associated with compliance. The results of MGSEM show that trust has an indirect effect on compliance in the male group through satisfaction [β = 0.051, P < 0.05, 95% CI: (0.012, 0.116)]. In the female group, trust has a direct effect on satisfaction [β = 0.235, P < 0.05, 95% CI: (0.041, 0.406)] and compliance [β = 0.319, P < 0.01, 95% CI: (0.086, 0.574)]. This study reveals the mechanisms of self-care compliance, trust, and satisfaction among Chinese hypertensive patients. Its findings may serve as a reference for guiding primary healthcare providers to improve hypertension patients' compliance and implement gender-targeted health interventions.

Family physician services and blood pressure control in China: A population-based retrospective cohort study.

Given the importance of continuous family physician (FP) care in the management of hypertension, we explored the effects of such care among hypertensive patients in China, a country where such care is generally underutilized. We examined the longitudinal association between the use and continuity of FP services and health outcomes including blood pressure (BP) control rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP). We conducted a population-based cohort study using data from the retrospective regional electronic health record database in Xiamen City, China. The study considered 18,119 hypertensive patients aged over 18 years who had at least two visits to a health center in the preceding 12months. The generalized estimating equation model was adopted to estimate the longitudinal association between FP service utilization and health outcomes. Hypertensive patients treated by their own FPs had a higher BP control rate (OR = 1.14, 95% CI: 1.02-1.28) and lower DBP (-0.36mmHg, 95% CI: -0.52 to -0.20) than those without a FP or those with a FP but treated by a general community physician (GCP). Compared with hypertensive patients treated exclusively by GCPs, patients treated continuously and exclusively by a FP were 45% more likely to have their BP under control (OR = 1.45, 95% CI: 1.32-1.60), and their SBP and DBP were lower by 0.6mmHg (95% CI: -0.78 to -0.39) and 0.6mmHg (95% CI: -0.79 to -0.47), respectively. Hypertensive patients continuously treated by their own FPs performed better in terms of BP control rate, SBP and DBP values. In addition, the number and continuity of FP visits were associated with better BP control.

Analysis of prescription status of antihypertensive drugs in Chinese patients with hypertension based on real-world study

Background Globally, the prevalence of hypertension and the accompanying burden of cardiovascular disease are increasing. Through drug utilization research, we can understand the prescription status of hypertension patients and promote rational drug use. The purpose of this retrospective study was to describe the current prescription pattern of antihypertensive drugs in Chinese patients and determine the compliance level of treatment guidelines. Materials and methods Around 11.1 million patients who received a prescription for antihypertensive therapy between January 2021 to December 2021 were obtained from a database of Hangzhou Kang Sheng Health Consulting CO., Ltd. Results The mean age of hypertensive patients was 54.75 ± 12.98 years. About 6.7 million (60.30%) were males. About 46.07% of patients had comorbidities. The most common classes of antihypertensive medications used were calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs). Around 78.33% of participants were on monotherapy. Diuretics + ARBs and Diuretics + CCBs + ARBs were the most commonly prescribed pattern in two-drug combination therapy and three-drug combination therapy, respectively. Conclusions CCBs and ARBs were the two most frequently prescribed for patients with hypertension. The prescription pattern of antihypertensive medications in the study largely complied with recommended Chinese hypertension guidelines. Key messages Cardiovascular disease is the most common complication of hypertension. Calcium channel blockers (CCBs) and angiotensin II receptor blockers (ARBs) are the two most commonly used drugs for hypertension patients in China. The proportion of combination prescription pattern in Chinese hypertensive patients is low.

Association of serum uric acid levels with cardiovascular and all-cause mortality in hypertensive patients in China: a cohort study

Threshold effect of plasma total homocysteine levels on cognitive function among hypertensive patients in China: A cross-sectional study

BackgroundIncreased plasma total homocysteine (tHcy) is an influencing factor of cognitive impairment in the general population. However, studies on the relationship between the risk of cognitive impairment and plasma tHcy levels in patients with hypertension are limited. This study aimed to explore the association between plasma tHcy levels and cognitive function assessed by MMSE scores among hypertensive patients in China.MethodsA total of 9,527 subjects from the Chinese Hypertension Registry Study participated in this study. Plasma tHcy levels were quantified by high-performance liquid chromatography using a fluorescence detector. Cognitive assessment was performed using the Mini-Mental State Examination (MMSE). Linear regression models, two piecewise linear regression models, and smoothing curve fitting were applied to determine the relationship between plasma tHcy levels and cognitive function.ResultsThis analysis included 9,527 Chinese hypertensive adults. Based on the results of linear regression models, a negative relationship was identified between plasma tHcy levels and MMSE scores [beta coefficient (β) per standard deviation (SD) increase: −0.26, 95% confidence interval (CI) −0.35, −0.16, P &amp;lt; 0.001]. The fully adjusted smooth curve fitting presented a nonlinear between plasma tHcy levels and MMSE scores. The threshold effect analysis showed that the inflection point of tHcy was about 27.1 μmol/L. The effect size [β (95% CI)] per SD increase in plasma tHcy concentrations on MMSE scores was −0.93 (−1.24, −0.6) on the left side and −0.07 (−0.24, 0.10) on the right side of the inflection point (P-value for log-likelihood ratio (LLR) test was &amp;lt;0.001). Moreover, subgroup analyses revealed that sex could influence the negative association between plasma tHcy levels and MMSE scores up to a specific threshold (P-value for interaction &amp;lt;0.001). Linear regression models indicated that there was an enhanced inverse association between tHcy levels and MMSE scores in female patients with tHcy concentrations less than 26.9 μmol/L compared to male patients with tHcy concentrations less than 32.0 μmol/L.ConclusionsPlasma tHcy levels had a threshold effect on MMSE scores among hypertensive patients in China. Increased plasma tHcy levels were independently inversely associated with cognitive decline among hypertensive patients with tHcy concentrations &amp;lt;27.1 μmol/L.

Follow-up management service and health outcomes of hypertensive patients in China: A cross-sectional analysis from the national health service survey in Jiangsu province.

BackgroundHypertension is a major cause of early mortality worldwide. Health follow-up management services can encourage patients with hypertension to improve their health behavior and outcomes. However, a lack of studies on the relationship between specific factors of follow-up management and both subjective and objective health outcome among hypertensive patients exists. The current study investigated the relationship between service content, frequency, mode, and institutions of follow-up management and health outcomes among Chinese hypertensives.MethodsData were obtained from the sixth National Health Service Survey (NHSS) of Jiangsu Province, which was conducted in 2018. Descriptive statistics were used to analyze the sample characteristics and the utilization of follow-up management services. Both multiple linear regression and logistic regression were used to estimate the association of follow-up management service and other factors with hypertensives' subjective and objective health outcomes.ResultSome respondents (19.30%) reported hypertension, and 75.36% of these patients obtained follow-up management services. Hypertensive patients' subjective health outcome self-reported health status and objective health outcome blood pressure (BP) control were found to be significantly associated with follow-up management services. The outcomes were both significantly improved by a high frequency of management services, a high level of follow-up providers, the mode of visiting healthcare facilities and/or calling, and receiving instructions on medication use. However, inquiring about patients' symptoms was negatively associated with self-reported health status and BP control. In addition, BP measurement was significantly and positively associated with hypertensive patients' self-reported health status; the patients receiving lifestyle guidance were more likely to have their BP levels under control.ConclusionsHypertension management strategies should further focus on the frequency of healthcare follow-up management via categorization of the follow-up services and appropriate adjustment of service delivery modes to optimize health follow-up management for hypertensives further improve their outcomes. Meanwhile, complementary policies are also needed to address other socioeconomic factors that can promote good health conditions for hypertension patients.

Detection Rate and Influencing Factors of Microalbuminuria in Hypertensive Patients

Abstract Background To investigate the detection rate and relevant influencing factors of microalbuminuria (MAU) in hypertensive patients in China. Methods A cross-sectional survey was conducted in 181,053 hypertensives from 600 hospitals across China. A questionnaire was used to collect information including patients’ risk factors, disease conditions, and antihypertensive drug treatment. Blood pressure was measured, and urine albumin to creatinine ratio was determined by urine strips. Patients were divided into the following subgroups: hypertension only, hypertension with and without MAU, cardiovascular risk factors, atherosclerotic cardiovascular disease (ASCVD), and single or combination drug therapy. Results A total of 136,483 patients with hypertension were enrolled. Patients with MAU, risk factors, and ASCVD or treated with combination drug therapy had significantly higher blood pressure compared with their corresponding counterparts (all P &amp;lt; 0.001). The detection rate of MAU was 27.8%, 25.7%, 29.1%, and 33.4% in hypertension only, hypertension with cardiovascular risk factors, hypertension with ASCVD, and hypertension with cardiovascular risk factors and ASCVD, respectively. Multivariate logistic regression analysis showed that age &amp;lt; 45 years, female, body mass index ≥ 28 kg/m2, living in Western China, living in Northeastern China, hypertension with risk factors and ASCVD, and combination drug therapy were positively correlated with MAU. Conclusions The detection rate of MAU is the highest in hypertensive patients with cardiovascular risk factors and ASCVD, and their blood pressure control is poor. Risk factor control and better blood pressure management are recommended.

Evaluation of the Community-Based Hypertension Management Programs in China.

PurposeThe National Essential Public Health Services Package (NEPHSP), a set of community-based hypertension management programs, was launched by the Chinese government in 2009. However, the data are limited for the comprehensive evaluation of NEPHSP on hypertension management. This study was to estimate the effect of NEPHSP on hypertension control nationwide in China.MethodsData were from China Hypertension Survey (CHS). The participants (n = 119,412) aged ≥35 years with hypertension were included in the analysis. Further, a subset of 64,188 diagnosed hypertensive patients were analyzed to evaluate the effect of NEPHSP by comparing the ones covered and not covered by NEPHSP. Blood pressure (BP) was measured by trained staff using a validated digital portable monitor in local communities or clinics.ResultsAmong adults aged ≥35 years with hypertension, the coverage of NEPHSP was 25.6% and increased with age. The coverage was significantly higher in women than in men (P < 0.001). Among the 64, 188 diagnosed hypertensive patients, compared to the control group (not covered by NEPHSP), the mean systolic and diastolic BPs were 2 mmHg and 1.6 mmHg lower in NEPHSP group, respectively. The rate of treatment for hypertension was significantly higher in NEPHSP group than the control group (93.0% vs. 81.4%, P < 0.001), and the rate of BP control was also significantly higher in NEPHSP group than the control group (35.9% vs. 29.6%, P < 0.001). Furthermore, similar trends were found in rural and urban, as well as in men and women.ConclusionsOur results showed that NEPHSP is effective in improving hypertension treatment and control in hypertensive patients in China. However, the coverage of NEPHSP was still low.

A behavior change wheel-based interactive pictorial health education program for hypertensive patients with low blood pressure health literacy: study protocol for a randomized controlled trial

BackgroundThe prevalence of hypertension is increasing worldwide. Hypertension self-management usually involves the application and consideration of oral, written, or quantitative information. Hypertensive patients in China have limited high blood pressure health literacy (HBP-HL), which may lead to poorer clinical outcomes. This study aims to determine the feasibility and effectiveness of an interactive pictorial health education program based on behavior change wheel (BCW) theory and its effect on HBP-HL, self-efficacy, self-management ability, and health-related quality of life (HRQOL) in hypertensive patients with low HBP-HL.MethodsThis study is a randomized controlled trial (RCT). One of the municipal districts in Huzhou, China, will be randomly selected, and two communities with similar conditions within this district will be screened and selected. A total of 120 hypertensive patients aged 18 years and older will be recruited from these two community settings. One of the communities will be randomly allocated to an interactive pictorial health education program conducted by a comprehensive health literacy strategy that includes (i) training participants in effective health communication skills that address issues encountered in seeking medical care and (ii) the use of self-developed interactive pictorial hypertension education to improve patient understanding and behaviors versus a control group (routine community lecture health education only). The primary outcome measure is HBP-HL. Secondary outcomes are self-efficacy, self-management ability, HRQOL, social support, and improvement in blood pressure. Outcomes will be collected at 6, 9, and 12 months from trial entry.DiscussionThe strengths of this study are the establishment of a new health management program for hypertensive patients that closely combines BCW theory and health literacy. This trial has the potential to improve HBP-HL in hypertensive Chinese patients with low health literacy to improve the self-management of hypertension and help control blood pressure.Trial registrationClinical Trials.gov Protocol Registration and Results System ID NCT04327102.

Medication Adherence and Perceived Social Support of Hypertensive Patients in China: A Community-Based Survey Study.

PurposePrevious studies suggested perceived social support has impact on medication adherence among hypertensive patients, but did not simultaneously elucidate the different contents or key providers of social support that patients perceived. This study was to identify the contents and providers of perceived social support beneficial for improving medication adherence among hypertensive patients in China, which could prove important for targeted interventions.Patients and MethodsFollowing a multi-stage stratified sampling framework, a total of 903 hypertensive patients from 12 primary health institutions across a middle-income city were recruited from April to June 2021. Medication adherence was measured using the Chinese version of the Morisky, Green and Levine scale; perceived social support was determined using the name generator method. A binary logistic regression model was performed to identify the association between medication adherence and perceived social support. The contents of support included informational, emotional, and instrumental support (finances and caregiving). The support providers included spouse/partner, children, parents, siblings, other relatives, and friends.ResultsA total of 506 (56.04%) patients optimally adhered to their antihypertensive medication. Female, older, urban patients, patients with shorter duration of hypertension and antihypertensive medications used showed better adherence (P<0.05). Optimal medication adherence was positively associated with the overall score of caregiving support (adjusted odds ratio [AOR] = 1.128; 95% confidence interval [CI] = [1.013–1.257]), informational support from the spouse/partner (AOR = 1.574; 95% CI = [1.112–2.227]), emotional support from the spouse/partner (AOR = 1.430; 95% CI = [1.032–1.981]), financial support from the spouse/partner (AOR = 1.439; 95% CI = [1.069–1.937]) and caregiving support from the spouse/partner (AOR = 1.652; 95% CI = [1.130–2.414]), whereas optimal medication adherence was negatively associated with caregiving support from friends (AOR = 0.499; 95% CI = [0.286–0.872]).ConclusionInformational, emotional, financial and caregiving support from spouses/partners have positive impacts on optimal medication adherence of hypertensive patients of community-level. Community-based interventions designed to improve medication adherence of hypertensive patients should target both patients and their spouses/partners; spouses/partners could be encouraged to provide various support to improve the medication adherence of hypertensive patients.

Effectiveness of a Transtheoretical Model-Based Intervention to Improve Blood Pressure Control of Hypertensive Patients in China: A Clustered Randomized Controlled Trial.

BackgroundHypertension can result in great cardiovascular risk, while medication adherence and blood pressure control of patients were suboptimal. Therefore, we conducted a 12-month clustered randomized controlled trial to evaluate the effectiveness of transtheoretical model (TTM)-based health intervention mode on blood pressure of Chinese newly-diagnosed hypertensive patients.MethodsThis trial was conducted in six primary healthcare centers, Shunyi District, Beijing, China from September 2016 to September 2017. A total of 400 patients were included and randomized, 194 patients in the control group and 206 patients in the intervention group. Patients in the intervention group received TTM-based health intervention and those in the control group received usual care. Multilevel modeling was used to adjust for clustering effect and repeated measurements.ResultsSystolic blood pressure of patient was reduced by 4.534 mm Hg at 3-month follow-up [95% CI (−3.054, −1.403), p = 0.005], 3.982 mm Hg at 6-month follow-up [95% CI (−7.387, −0.577), p = 0.022], and 5.803 mm Hg at 12-month follow-up [95% (−9.716, −1.891), p = 0.004]. Diastolic blood pressure of patient was reduced by 3.383 mm Hg at 3-month follow-up [95% CI (−5.724, −1.042), p = 0.005], 0.330 mm Hg at 6-month follow-up [95% CI (−2.870, 2.210), p = 0.799], and 3.129 mm Hg at 12-month follow-up [95% CI (−6.048, −0.21), p = 0.036]. Medication adherence of patients was improved at all the three time points. For stages of change for taking medication, patients in the intervention group were 8.401-fold more likely to be in a higher stage at 3-month follow-up [95% CI (4.186, 16.862), p < 0.001]. The odds ratio of being in a higher stage was 8.454 at 6-month follow-up [95% CI (3.943, 18.123), p < 0.001] and 19.263 at 12-month follow-up [95% CI (7.979, 46.505), p < 0.001].ConclusionTranstheoretical model-based health intervention might be a promising strategy to improve medication adherence of newly-diagnosed hypertensive patients in community.

Study on Diet Intervention Factors of Elderly Hypertensive Patients in China Based on COM-B Model

The objective of the current study was to explore the factors that affect the dietary management of elderly hypertensive patients, and to provide a scientific reference for the selection and optimization of comprehensive prevention and treatment strategies for blood pressure control and health management for elderly hypertensive patients in the community, and to improve patients' self-management ability and blood pressure control effects. Based on the three necessary conditions of the COM-B framework: ability, motivation and opportunity, the factors affecting the eating behavior of hypertensive patients were analyzed, and the corresponding intervention plan was then formulated. The conclusion is that lack of awareness and social support is the main factor influencing dietary intervention in elderly hypertensive patients in the community. In addition, community-based dietary management of hypertension mainly includes health education, psychological intervention, exercise guidance and dietary intervention. At the same time, improving the blood pressure control effect and dietary management level of elderly hypertensive patients requires the joint efforts and cooperation of the government, community, patients and their families.

Uncaria Rhynchophylla attenuates angiotensin Ⅱ-induced myocardial fibrosis via suppression of the RhoA/ROCK1 pathway

Uncaria rhynchophylla (UR), a traditional Chinese medicine, has been proven effective in treating hypertensive patients in China. However, the mechanisms of action of UR in reducing hypertension and myocardial fibrosis are still unclear. The purpose of this study was to explore the role of UR in an angiotensin Ⅱ (Ang Ⅱ) induced mouse model. The mice were randomly divided into 5 groups and infused with Ang Ⅱ (500 ng/kg/min) or saline, then administered UR (0.78, 1.56 or 3.12 g/kg/d) or saline for 4 weeks. UR treatment significantly attenuated the elevation of blood pressure caused by Ang Ⅱ. It enhanced myocardial function and attenuated the increase in the heart weight index and the pathological changes in the Ang Ⅱ-induced hypertensive mice. Furthermore, UR treatment inhibited cardiac fibrosis and significantly down-regulated collagen I, collagen Ⅲ, and α-SMA protein expression in cardiac tissues. UR also attenuated the expression of RhoA, ROCK1, CTGF, and TGF-β1. In cultured cardiac fibroblasts stimulated with Ang Ⅱ, UR significantly down-regulated the expression of Collagen I, Collagen III, RhoA, ROCK1, and α-SMA. In summary, UR can significantly attenuate Ang Ⅱ-induced hypertension and cardiac fibrosis, partly via suppression of the RhoA/ROCK1 signaling pathway.
