Effects of psychological stress on hypertension in middle-aged Chinese: a cross-sectional study

Association between lifestyle factors and hypertension control in Indonesian primary healthcare settings: A cross-sectional study

Introduction

A healthy lifestyle influences hypertension control. However, studies investigating the effects of lifestyle on hypertension remain elusive. This study aimed to analyse the association between lifestyle factors and hypertension control among patients with hypertension.

Methods

This cross-sectional exploratory study was conducted from June to December 2022 among 265 patients with hypertension from the Pusat Kesehatan Masyarakat. The status of hypertension control was assessed by checking the serial blood pressure. The physical activity (PA) level, sleep quality, stress level and eating pattern were measured using the Global Physical Activity Questionnaire; Pittsburgh Sleep Quality Index; Depression Anxiety Stress Scale-21; and 24-Hour Food Recall Questionnaire, Adolescent Food Habits Checklist and Emotional Eating Scale, respectively. Stepwise binary logistic regression and a generalised linear model were used for the statistical analysis.

Results

Approximately 72.2% of the participants had uncontrolled hypertension. The majority showed a low PA level (46%), normal stress level (94.7%), good sleep quality (80%), low caloric intake (95.5%), neutral food habit (55.5%) and low emotional eating (93.2%). Sex (P=0.030), age (P=0.018), PA level (P=0.011), sleep quality (P=0.032) and stress level (P=0.030) significantly influenced hypertension control. Specifically, moderate (odds ratio [OR]=5.868, 95% confidence interval [CI]=3.024-11.798, P=0.000) and vigorous PA levels (OR=2.188, 95% CI=1.026-4.678, P=0.042) were significantly associated with hypertension control.

Conclusion

Moderate and vigorous PA levels are lifestyle factors that may play a role in controlling hypertension.

Association Between Self-Perception of Aging and Long-Term Mortality in Elderly Patients with Hypertension in Rural China: A Possible Beneficial Effect of Nut Intake

Purpose

Previous research has consistently shown that self-perception of aging (SPA) is an important predictor of health and longevity, while Chinese rural elderly patients with hypertension had poorer SPA. Whether it was associated with their mortality kept unknown. The objective of this study was to investigate the long-term mortality and analyze the association between SPA and this mortality in the specific context of rural elderly patients with hypertension.

Patients and Methods

This study is a longitudinal investigation of the mortality in elderly patients with hypertension in rural Suzhou, China. Sociodemographic and clinical data, SPA, and six-year mortality were investigated. We used binary logistic regression and subgroup analyses to assess the effect of SPA at baseline on six-year mortality.

Results

A total of 280 hypertensive patients aged 60 years and older participated in the study, of whom 21 died, with a six-year mortality rate of 7.5%. After controlling for covariates, the "Emotional representation" dimension (OR=2.824, 95% CI:1.034-7.712) in SPA remained a risk factor for death. In subgroup analyses of the group aged 75 years and older, high scores on the "Timeline cyclical" (OR=14.125, 95% CI: 1.258-158.593) and "Emotional representations" (OR=2.567, 95% CI:1.066-6.182) dimensions were associated with a higher risk of death, while weekly nut intake may have mitigated the negative SPA effect on mortality.

Conclusion

Poorer self-perception of aging was associated with a high risk of mortality in rural elderly patients with hypertension, while the habit of weekly nut intake might help reduce this risk in the group aged 75 years or older.

Factors influencing blood pressure variability in postmenopausal women: evidence from the China Health and Nutrition Survey

BACKGROUND

The aim is to identify the factors influencing blood pressure variability in postmenopausal women based on the China Health and Nutrition Survey (CHNS).

MATERIAL AND METHODS

The data on postmenopausal women between 1993 and 2015 were extracted from the CHNS. Group-based trajectory modeling was used to analyze the development track of blood pressure changes, based on which the subjects were separately divided into two groups for systolic blood pressure (SBP) and diastolic blood pressure (DBP). Univariate and multivariate analyzes were performed to analyze the factors influencing SBP and DBP.

RESULTS

A total of 346 women were eligible for the study. Group-based trajectory modeling showed two different trajectories of blood pressure, including the low-level, slowly developed type and the high-level, rapidly developed, stable type of SBP, as well as the low-level, slowly developed type and the high-level, slowly developed type of DBP. In multivariate analysis, age (odds ratio [OR]: 1.118, 95% confidence interval [CI]: 1.082-1.156), body mass index (BMI) (OR: 2.239, 95%CI: 1.010-4.964), antihypertensive agents (OR: 7.293, 95%CI: 2.191-24.275), hip circumference (OR: 1.069, 95%CI: 1.014-1.128) and marital status (OR: 3.103, 95%CI: 1.028-9.361) were found to be the significant factors influencing SBP; age (OR: 1.067, 95%CI: 1.039-1.096), alcohol consumption (OR: 2.741, 95%CI: 1.169-6.429), antihypertensive agents (OR: 4.577, 95%CI: 1.553-13.492), hip circumference (OR: 1.093, 95%CI: 1.049-1.138), and marital status (OR: 3.615, 95%CI: 1.228-10.644) were the predominant factors influencing DBP.

CONCLUSIONS

In postmenopausal women, age, BMI, antihypertensive agents, hip circumference, and marital status are associated with SBP changes, while age, alcohol consumption, antihypertensive agents, hip circumference, and marital status with DBP variability.

Latent profile analysis of depression in non-hospitalized elderly patients with hypertension and its influencing factors

BACKGROUND

Hypertension is a common chronic disease in the elderly, which seriously affects people's physical and mental health, leading to anxiety, depression and other symptoms. To analyze the types of depression that may occur in elderly patients with non-hospitalized hypertension and explore its influencing factors can reduce the level of depression and improve the quality of life.

METHODS

Based on the data of the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS), latent profile analysis (LPA) was used to establish the potential profile model of elderly hypertensive patients with depression, and multiple logistic regression analysis was employed to explore the influencing factors of patients with depression.

RESULTS

3514 elderly patients with hypertension could be divided into three potential characteristics of depression: low-level (13.9 %), medium-level (51.9 %) and high-level (34.2 %). Multiple logistic regression showed that anxiety, IADL, age, exercise, economic level, hearing difficulty, self-reported health and visual function predicted the depression of the medium-level in the comparison between the low-level and the medium-level; taking low levels as a reference, anxiety, IADL, co-residence of interviewee, age, exercise, self-reported health marital status and visual function can predict the depression of high-level; anxiety, exercise, self-reported health and marital status predicted the depression of the high-level in the comparison between the medium-level and the high-level.

LIMITATIONS

(1) This study is a cross-sectional study; (2) due to data limitations, other influencing factors may be ignored.

CONCLUSION

Depression in elderly patients with hypertension was divided into three potential profiles, which had obvious classification characteristics.

Hypertension-related distress and its associated factors: findings from an urban primary health centre of South Delhi, India

Background

Living with hypertension (HTN) has been found to cause distress, which adversely affects one's self-care and may lead to elevated blood pressure. There is a paucity of data regarding the prevalence of HTN-related distress. This study was conducted to estimate the prevalence of HTN-related distress among adults with HTN attending an outpatient department in an urban primary health centre and to determine the factors associated with distress.

Methods

This was a cross-sectional study conducted at the outpatient department of an urban primary health centre in Delhi, India. The enrolled participants were administered a questionnaire, which included a Distress Scale for patients with diabetes mellitus and/or hypertension (DSDH17 M) (to assess for HTN-related distress) and Health-Related Quality of Life, Healthy Days Measure. A descriptive analysis was performed. Factors associated with HTN-related distress were tested using logistic regression.

Results

One hundred forty-one participants were enrolled in this study. Most were women (73.76%) with a mean age of 60.15 years (standard deviation [SD]: 0.78). The prevalence of HTN-related distress (average DSDH17 M score ≥3) was 14% (95% confidence interval [CI]: 9.30-21.03). Patients with HTN-related distress had significantly poor health and reported a greater number of days where they were physically or mentally unhealthy. Patients with uncontrolled blood pressure had six times the odds (95% CI: 1.69-21.77, P value = 0.006) of HTN-related distress compared to those with controlled blood pressure.

Conclusions

Hypertension-related distress was present in 14% of adults with HTN. Patients with uncontrolled blood pressure had six times the odds of HTN-related distress.

Hypertension in China: epidemiology and treatment initiatives

The past two to three decades have seen a steady increase in the prevalence of hypertension in China, largely owing to increased life expectancy and lifestyle changes (particularly among individuals aged 35-44 years). Data from the China hypertension survey conducted in 2012-2015 revealed a high prevalence of grade 3 hypertension (systolic blood pressure ≥180 mmHg and diastolic blood pressure ≥110 mmHg) in the general population, which increased with age to up to 5% among individuals aged ≥65 years. The risk profile of patients with hypertension in China has also been a subject of intense study in the past 30 years. Dietary sodium and potassium intake have remained largely the same in China in the past three decades, and salt substitution strategies seem to be effective in reducing blood pressure levels and the risk of cardiovascular events and death. However, the number of individuals with risk factors for hypertension and cardiovascular disease in general, such as physical inactivity and obesity, has increased dramatically in the same period. Moreover, even in patients diagnosed with hypertension, their disease is often poorly managed owing to a lack of patient education and poor treatment compliance. In this Review, we summarize the latest epidemiological data on hypertension in China, discuss the risk factors for hypertension that are specific to this population, and describe several ongoing nationwide hypertension control initiatives that target these risk factors, especially in the low-resource rural setting.

Magnitude of hypertension and its association with obesity among employees of Wallaga University, Ethiopia: a cross-sectional study

OBJECTIVE

To determine the magnitude of hypertension, its association with obesity and the associated factors among employees of Wallaga University, Ethiopia.

DESIGN, SETTING AND PARTICIPANTS

This institution-based cross-sectional study was employed among 588 employees of the university. Respondents were selected by stratified random sampling technique and interviewed with the aid of a structured questionnaire.

THE MAIN OUTCOME MEASURED

Hypertension and obesity were measured using WHO Stepwise approach and recommendations. We used a stratified random sampling technique to select 588 employees of the university from 3 August 2021 to 15 October 2021. A structured questionnaire and anthropometric measurements were used for data collection. Multivariable logistic regression analysis was used to determine factors independently associated with hypertension. A p value less than or equal to 0.05 and its 95% confidence level was used to declare the statistical significance.

RESULTS

A total of 578 participants consented and completed the study, giving a response rate of 98.3%. The mean age of the respondents was 31.78 years with SD of 5.4. The overall prevalence of hypertension, general obesity and central obesity was 14.4% (95% CI 11.6% to 17.5%), 31.3% (95% CI 27.6% to 35.3%) and 37% (95% CI 33.1% to 41.1%), respectively. Obesity was significantly associated with hypertension (adjusted OR (AOR): 6.3; 95% CI 2.60 to 8.19). Age range from 35 to 46 (AOR 7.01; 95% CI 1.56 to 31.74), age ≥46 years (AOR 8.45; 95% CI 1.14 to 62.04), being non-academic staff (AOR 2.74; 95% CI 1.56 to 4.81), having additional income (AOR 2.48; 95% CI 1.08 to 5.70), physical inactivity (AOR 2.36; 95% CI 1.44 to 3.88) and poor practice of dietary salt consumption (AOR 1.65; 95% CI 1.01 to 2.87) were factors associated with hypertension.

CONCLUSION

One in seven, more than two in seven and nearly two in six of the employees of Wallaga University were hypertensive, centrally obese and generally obese, respectively. There was a positive association between obesity and hypertension. Comprehensive awareness creation and devising workplace intervention strategies are highly recommended to reduce the hypertension burden and associated obesity.

Data extraction, critical appraisal, and screening of all retrieved articles will be conducted by two independent reviewers. Statistical analysis will be performed using STATA-14 software packages. A random effect will be employed to demonstrate pooled estimates of hypertension among bank workers. For determinants of hypertension, an effect size with a 95% confidence interval will be analyzed.

Results

Data extraction and statistical analyses will begin after identifying the most pertinent studies and evaluating their methodological quality. Data synthesis and the presentation of the results are scheduled for completion by the end of 2023. After the review is completed, the results will be presented at relevant conferences and published in a peer-reviewed journal.

Conclusion

Hypertension is a major public health concern in Africa. More than 2 out of 10 people aged older than 18 years suffer from hypertension. A number of factors contribute to hypertension in Africa. These factors include female gender, age, overweight or obesity, khat chewing, alcohol consumption, and family history of hypertension and diabetes mellitus. To address the alarming rise in hypertension in Africa, behavioral risk factors should be given primary attention.

Species-Specific Effects of Planktonic Bacteria on the Predator-Induced Life-History Defense of Daphnia: Based on Hierarchical Cluster Analysis and Structural Equation Model

Planktonic bacteria are an important part of aquatic ecosystems and interact with zooplankton. However, it is still unclear whether different planktonic bacteria differentially interfere with the responses of zooplankton to their predators. Here, we investigated the effects of different planktonic bacteria, which were isolated and purified from natural lakes, on the anti-predation (Rhodeus ocellatus as the predator) defense responses of Daphnia magna. Our results showed that the effects of planktonic bacteria on the induced life-history defenses of Daphnia were species-specific. Bacteria which increased (e.g., Escherichia coli, Citrobacter braakii) Daphnia body size also promoted the induced defense of body size, whereas bacteria which decreased (e.g., Pseudomonas spp.) Daphnia body size also inhibited the induced defense of body size. In addition, the same bacteria had different effects on induced defense traits. Some bacteria (e.g., E. coli) promoted the induced defense of body size but reduced the induced defense of offspring number, whereas other bacteria (e.g., Aeromonas hydrophila, Aeromonas veronas) weakened the induced defense of body size but had no significant effect on the induced defense of offspring number. Moreover, the differential effects of planktonic bacteria on Daphnia's induced defenses were not related to the bacterial degradation of kairomone. This study illustrated, for the first time, the species-specific effects of planktonic bacteria on predator-induced responses of Daphnia. IMPORTANCE This study is the first to reveal the differential effects of different species of planktonic bacteria on fish kairomone-induced defense traits and energy redistribution in Daphnia. Our results not only help deepen the understanding of Daphnia's inducible defenses in environments containing a variety of bacteria but also provide insights into the energy reallocation involved in anti-predator defenses.

Ultra-Processed Food Consumption Associated with Incident Hypertension among Chinese Adults-Results from China Health and Nutrition Survey 1997-2015

Objective: Ultra-processed food (UPF) has been shown to increase the cardiometabolic health risks. We aimed to determine the association between UPF intake based on the NOVA classification and the risk of hypertension incidence during 1997−2015. Methods: Data from 15,054 adults aged ≥ 20 years (47.4% males) attending the China Nutrition and Health Survey (CNHS) were used. Food intake at each survey was assessed by a 3-day 24 h dietary recall and weighed food record method between 1997−2011. Cox regression was used to assess the association between UPF intake and incident hypertension. Results: During a mean average of 9.5 years (SD 5.5) of follow up, 4329 hypertension incident cases were identified. The incident rates (per 1000) for non-consumers and 1−49, 50−99, and ≥100 g/day of UPF intake were 29.5 and 29.5, 33.4, and 36.3, respectively. Compared with non-consumers, the hazard ratios (95% CI) for UPF intake of 1−49, 50−99, and >100 g/day were 1.00 (0.90−1.12), 1.17 (1.04−1.33), and 1.20 (1.06−1.35), respectively, (p = 0.001) after adjusting for potential confounding factors. There was a significant interaction between UPF intake and age with a higher risk in the younger group (<40 years) than in the older one. Conclusion: UPF consumption was dose-responsively associated with increased risk of hypertension among Chinese adults, especially in younger groups.

Intrasession Reliability Analysis for Oscillometric Blood Pressure Method Using a Digital Blood Pressure Monitor in Peruvian Population

Blood Pressure (BP) is one of the most used measured clinical parameters in health promotion and intervention. BP measures can vary due to different parameters, so we aim to study the intrasession test-retest reliability for an oscillometric method using a digital tensiometer in the Peruvian population aged over 15 with and without a diagnosis of hypertension (HT). Data were taken from the Demographic and Family Health Survey conducted in Peru in 2019. Technicians had to follow a standardized protocol on the conditions to carry out a valid and reliable measurement. Relative reliability was excellent in most cases (intraclass correlation coefficient > 0.9); absolute reliability was excellent (standard error of measurement < 5%) and smallest real difference < 10% in most cases. The Bland-Altman plot showed a systematic error of 2.36 for systolic BP in men and 2.16 in women, and 0.823 for diastolic BP in men and 0.71 for diastolic BP in women. Results suggest that the oscillometric method with a digital blood pressure monitor was reliable in absolute and relative terms in this population, so it could be used as a reliable control test to measure changes after an intervention.

Correlation of Hypertension Self-Care Activity Level Effects Factors with Perceived Stress in Uncontrolled Hypertensive Patients

BACKGROUND: Stress is associated with hypertension self-care behavior activity. Low self-care can cause hypertension and make hypertension uncontrolled. Patients with uncontrolled hypertension are very susceptible to experiencing stress through self-care activities that they must do. AIM: This study aims to identify the role of perceived stress on the self-care behavior of patients with uncontrolled hypertension. This study aims to assess the correlation of hypertension self-care activity level effect factors with perceived stress in patients with uncontrolled hypertension. METHODS: This quantitative study with a cross-sectional design recruited 383 patients with uncontrolled hypertension at a community health center. The sampling technique is consecutive sampling. Perceived stress was assessed using Perceived Stress Sclae (PSS) and hypertension self-care activities were assessed using Hypertension Self-Care Activity Level Effect (H-SCALE). Data were analyzed using chi-square and multivariate test. RESULTS: All respondents experienced stress, where 55.6% severed perceived stress and 44.4% moderate perceived stress. Severe stress occurs 60% in middle age, 54.2% in the elderly, 56.6% of male respondents, and 55.1% of female respondents. About 71.9% of respondents do not go to school, 69.2% are highly educated, and 56.6% of respondents do not work. Medication non-adherence (p = 0.000; OR = 0.941; 95% CI = 0.911–0.973) and weight management non-adherence (p = 0.006; OR = 0.956; 95% CI = 0.927–0.987) were positively correlated with the level of perceived stress in patients uncontrolled hypertension. CONCLUSION: Improving coping strategies for stress by designing educational provisions about medication and weight management (diet and physical activity) are easily understood by people who do not experience education. Continuity and comprehensive education are needed.

Association between self-reported snoring and hypertension: a systematic review and meta-analysis

OBJECTIVES

The purpose of this study is to summarize the evidence for the association between snoring and hypertension and the effect of snoring on hypertension in men and/or women.

METHODS

We searched the articles in the Cochrane Library, PubMed, Scopus, Web of Science and Embase published up to 12 November 2020 to evaluate the association between snoring and hypertension. Studies were selected according to the predefined screening criteria and their qualities were assessed by Newcastle-Ottawa Quality Evaluation Scale. The odds ratio and 95% confidence interval were used as effective indicators. It was registered in PROSPERO with the number: CRD42021224912.

RESULTS

According to the inclusion/exclusion criteria, 11 studies including eight prospective cohort studies and three cross-sectional studies were included. The results showed that compared with non-snoring participants, snoring significantly increased the risk of hypertension in both men and women [odds ratio (OR) = 1.32, 95% confidence interval (CI), 1.23-1.42; men: odds ratio (OR) = 1.32; 95% confidence interval (CI), 1.18-1.49; women: odds ratio (OR) = 1.26; 95% confidence interval (CI), 1.14-1.40]. Besides, the risk of hypertension was significantly increased when the snoring frequency was ≥4 nights/week [frequency≥4 nights/week: odds ratio (OR) = 1.42; 95% confidence interval (CI), 1.21-1.66; 4 nights/week >frequency>0: odds ratio (OR) = 1.23; 95% confidence interval (CI),1.13-1.34].

CONCLUSIONS

Snoring is considered as an independent predictor of hypertension in both men and women, which may play a role in the prevention and control of hypertension. People who snore frequently should pay close attention to their blood pressure levels to prevent hypertension.

Prevalence of and risk factors for hypertension in Ethiopia: A systematic review and meta-analysis

BACKGROUND

A number of epidemiological studies were performed to know the prevalence of and the risk factors for hypertension. However, these studies reported inconsistent results. As a result, this systematic review and meta-analysis were planned to generate representative data on the prevalence of and risk factors for hypertension among the Ethiopian adult population.

METHODS

Five electronic databases, namely, PubMed, Science Direct, Google Scholar, Hinari, and African Journals Online, were searched for studies published in English from 1 January 2010 to 31 August 2020. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument and Newcastle-Ottawa scale were used for data extraction and quality assessment for this review. Stata version 14 statistical software was used for the analysis, and due to high heterogeneity a random effects model was used for meta-analysis at 95% confidence interval (CI).

RESULTS

In this review, 35 observational studies were included. The pooled prevalence of hypertension in Ethiopia was 20.63% (95% CI [18.70, 22.55]) with the I 2 value of 96.1%. Older age (≥40 years) (adjusted odds ratio [AOR]: 3.46 [95% CI: 2.67, 4.49]), urban residence (AOR: 1.47 [95% CI: 1.28, 1.70]), educational status less than grade 12 (AOR: 1.67 [95% CI: 1.38, 2.01]), family history of hypertension (AOR: 4.33 [95% CI: 2.95, 6.34]), diabetes mellitus (DM) (AOR: 5.18 [95% CI: 3.01, 8.88]), body mass index (BMI) ≥25 (AOR: 3.79 [95% CI: 2.61, 5.50]), central obesity (AOR: 1.91 [95% CI: 1.09, 3.36]), and alcohol consumption (AOR: 1.72 [95% CI: 1.26, 2.34]) were the identified risk factors for hypertension.

CONCLUSION

The pooled prevalence of hypertension is relatively higher as compared to the previous reports in Ethiopia. Older age, urban residence, lower educational coverage, family history of hypertension, DM, BMI ≥25, alcohol consumption, and central obesity were the risk factors for hypertension. The governments and stakeholders should design an appropriate strategy to prevent and control the disease in the Ethiopian population.

The efficacy of cognitive behavioral therapy-based interventions on patients with hypertension: A systematic review and meta-analysis

Recently, the benefits of cognitive behavioral therapy (CBT)-based interventions for patients with hypertension have been recognized, but there has been no systematic review that has comprehensively analyzed the efficacy of CBT on health outcomes in this population. We aimed to explore the therapeutic effect of CBT-based interventions on hypertension patients through a meta-analysis. Relevant randomized controlled trials (RCTs) were obtained by searching electronic databases. The primary outcomes were physiological indicators (blood pressure, blood lipid profile). Secondary outcomes were psychological indicators (anxiety, depression), and the quality of sleep. Stata version 15.0 software was used to analyze the results. A total of 15 RCTs were included. The main analysis revealed that CBT-based interventions reduced systolic pressure: -8.67 (95% CI: -10.67 to -6.67, P = 0.000); diastolic pressure: -5.82 (95% CI: -7.82 to -3.81, P = 0.000); total cholesterol levels: -0.43 (95% CI: -0.76 to -0.10, P = 0.010); depressive symptoms: -3.13 (95% CI: -4.02 to -2.24, P = 0.000); anxiety symptoms: -3.63 (95% CI: -4.40 to -2.87, P = 0.000); and improved quality of sleep: -2.93 (95% CI: -4.40 to -1.47, P = 0.000). Additionally, the results of subgroup analysis indicated that long-term group-based CBT-based interventions were particularly beneficial for blood pressure management in hypertension patients. CBT-based interventions are effective in reducing systolic pressure, diastolic pressure, total cholesterol levels, anxiety symptoms, depressive symptoms, and improving quality of sleep in hypertension patients.

Gut microecology: Why our microbes could be key to our health

The human body contains a large number of microorganisms, and the gut microecology environment contains the largest number and types of microorganisms. The structure and function of gut microbiota are closely related to the health of the human body. In a cascade of studies, the diversity of gut microbiota and its metabolite often found changed in patients or mice model. What kind of gut microbiota that associated with the occurrence or treatment of diseases were also found in many studies. Gut microbiota and its products can affect the function of the human body. Short-chain fatty acids, bile acid, indoles and so on were found can regulate the inflammation, immune response to affect the process of diseases. Immune cells like natural killer T cells, CD3 + T cells were also found had a link to gut microbiota which associated with diseases. Changes in gut microbiota are associated with changes in the body's major systems, such as the digestive system, the endocrine system, the cardiovascular system, the endocrine and metabolic system, the urinary system diseases, the respiratory system and so on. It is of great significance to study gut microecology for the prevention and treatment of various human diseases.

Prevalence of Hypertension and Associated Factors among the Outpatient Department in Akaki Kality Subcity Health Centers, Addis Ababa, Ethiopia

Background

Fatalities from hypertension in East Africa are increasing, even though they decreased in western industrial regions. Older age, being female, illiterate, smoking, physical inactivity, and high waist circumferences are major risk factors for the development of hypertension. The prevalence of hypertension among Federal Ministry Civil servants in Addis Ababa, Ethiopia, has found to be high; which is an indication for institution-based hypertension-screening programs.

Objective

Prevalence of hypertension and associated factors among the outpatient department in Akaki Kality Subcity Health Centers, Addis Ababa, Ethiopia. Methodology. Facility-based cross-sectional study was carried out on systematically sampled 401 out-department patients whose age was greater than or equal to 18 years in four government health centers in Addis Ababa. Data collection took place from March 10, 2018, to April 06 2018. Binary logistic regression analysis was carried out to identify predictors of hypertension.

Results

Patients had a mean age of 41.17 years (95% CI: 39.77–42.57). The prevalence of hypertension was 14% (95% CI: 13.653–14.347), and 30 (53.57%) were males. Alcohol drinkers were 11.844 times more likely to be hypertensive as compared to non-alcohol drinkers (AOR = 11.844, 95% CI: 3.596–39.014). Cigarette smokers were 16.511 times more likely to be hypertensive as compared to non-cigarette smokers (AOR = 16.511, 95% CI: 4.775–57.084). Khat chewers were 6.964 times more likely to be hypertensive as compared to non-khat chewers (AOR = 6.964, 95% CI: 1.773–26.889).

Conclusion

The prevalence of patients with hypertension was 14%. Alcohol drinking, cigarette smoking, khat chewing, body mass index ≥25 kg/m², and age ≥44 years old are major determinants identified by this study. Hence, appropriate management of patients focusing on the relevant associated factors would be of great benefit in controlling hypertension.

Self-rated health and psychological health among hypertensive patients in Palestine

The study has investigated the self-rated psychological health of hypertensive patients in Palestine. To that end, a stratified random sample of 502 hypertensive patients (aged ⩾ 18 years) was asked to complete a validated Arabic version of the General Health Questionnaire (GHQ-28). After collection, the data were analyzed using descriptive statistics, Mann-Whitney U test and logistic regression. In this study, it was found the mean scores for GHQ were statistically higher for females than males (p < 0.05). The females were found to be 1.701 (95% CI = 1.025-2.823) times more at risk of psychological disorders compared to males. In conclusion, improvement of social determinants of hypertensive patients can make a difference in their psychological/mental health.

Anxiety sensitivity and psychological distress among hypertensive patients: the mediating role of experiential avoidance

Hypertension is often associated with adverse psychosocial outcomes and psychological factors have been advanced for better explanatory models and to enhance the development of effective interventions in the treatment of hypertensive patients. Although the link between anxiety sensitivity (AS) and poor mental health outcomes has been established, the mechanism through which it results in psychological distress (PD) is not yet well understood. In addition to investigating the direct associations of AS and experiential avoidance (EA) to PD, the present study examines whether AS predicts adverse mental health outcomes via EA. Hypertensive patients (N = 240; women = 135; Mean age = 41.09, SD = 9.11 years) drawn from cardiology unit of a Nigerian teaching hospital completed the following measures: Psychological Distress Scale, Anxiety Sensitivity Index - 3, and Acceptance and Action Questionnaire. Results showed that that greater AS and greater EA predicted increased PD, even when controlling for age and gender. The mediation hypothesis was further supported suggesting that the association between AS with increase in PD was a function of heightened EA. These findings are consistent with the notion that acceptance of daily experiences may serve to buffer against the potential adverse mental health outcomes and may be a critical target for interventions to ameliorate PD in patients with chronic health conditions such as hypertension. Psychological interventions that deals with experiential avoidance could be used in the management of distressed hypertensive patients.

Psychosocial factors and hypertension prevalence among Ghanaians in Ghana and Ghanaian migrants in Europe: The RODAM study

Despite progress made to prevent and control hypertension, its prevalence has persisted in many countries. This study examined the associations between psychosocial factors and hypertension among Ghanaian non-migrants and migrants. Data were drawn from the Research on Obesity and Diabetes among African Migrants (RODAM) project. Findings show that among migrant women, those who experienced periods of stress at home/work had higher odds of hypertension. Among non-migrants, women with depression symptoms were more likely to be hypertensive. Furthermore, there was a positive association between negative life events and hypertension among non-migrant men. The findings highlight the importance of psychosocial factors in addressing hypertension prevalence in Ghanaian populations.

Hypertension linked to allostatic load: from psychosocial stress to inflammation and mitochondrial dysfunction

Although a large number of available treatments and strategies, the prevalence of cardiovascular diseases continues to grow worldwide. Emerging evidence supports the notion of counteracting stress as a critical component of a comprehensive therapeutic strategy for cardiovascular disease. Indeed, an unhealthy lifestyle is a burden to biological variables such as plasma glucose, lipid profile, and blood pressure control. Recent findings identify allostatic load as a new paradigm for an integrated understanding of the importance of psychosocial stress and its impact on the development and maintenance of cardiovascular disease. Allostasis complement homeostasis and integrates behavioral and physiological mechanisms by which genes, early experiences, environment, lifestyle, diet, sleep, and physical exercise can modulate and adapt biological responses at the cellular level. For example, variability is a physiological characteristic of blood pressure necessary for survival and the allostatic load in hypertension can contribute to its related cardiovascular morbidity and mortality. Therefore, the current review will focus on the mechanisms that link hypertension to allostatic load, which includes psychosocial stress, inflammation, and mitochondrial dysfunction. We will describe and discuss new insights on neuroendocrine-immune effects linked to allostatic load and its impact on the cellular and molecular responses; the links between allostatic load, inflammation, and endothelial dysfunction; the epidemiological evidence supporting the pathophysiological origins of hypertension; and the biological embedding of allostatic load and hypertension with an emphasis on mitochondrial dysfunction.

Self-reported hypertension in Northern China: a cross-sectional study of a risk prediction model and age trends

BACKGROUND

Hypertension is a major risk factor for the global burden of disease, particularly in countries that are not economically developed. This study aimed to evaluate risk factors associated with self-reported hypertension among residents of Inner Mongolia using a cross-sectional study and to explore trends in the rate of self-reported hypertension.

METHODS

Multi-stage stratified cluster sampling was used to survey 13,554 participants aged more than 15 years residing in Inner Mongolia for the 2013 Fifth Health Service Survey. Hypertension was self-reported based on a past diagnosis of hypertension and current use of antihypertensive medication. Adjusted odds risks (ORs) of self-reported hypertension were derived for each independent risk factor including basic socio-demographic and clinical factors using multivariable logistic regression. An optimized risk score model was used to assess the risk and determine the predictive power of risk factors on self-reported hypertension among Inner Mongolia residents.

RESULTS

During study period, self-reported hypertension prevalence was 19.0% (2571/13,554). In multivariable analyses, both female and minority groups were estimated to be associated with increased risk of self-reported hypertension, adjusted ORs (95% CI) were 1.22 (1.08, 1.37) and 1.66 (1.29, 2.13) for other minority compared with Han, increased risk of self-reported hypertension prevalence was associated with age, marital status, drinking, BMI, and comorbidity. In the analyses calculated risk score by regression coefficients, old age (≥71) had a score of 12, which was highest among all examined factors. The predicted probability of self-reported hypertension was positively associated with risk score. Of 13,421 participants with complete data, 284 had a risk score greater than 20, which corresponded to a high estimated probability of self-reported hypertension (≥67%).

CONCLUSIONS

Self-reported hypertension was largely related to multiple clinical and socio-demographic factors. An optimized risk score model can effectively predict self-reported hypertension. Understanding these factors and assessing the risk score model can help to identify the high-risk groups, especially in areas with multi-ethnic populations.

Associations between psychological stress and smoking, drinking, obesity, and high blood pressure in an upper middle-income country in the African region

The direction and magnitude of the associations between cardiovascular risk factors (CVRFs) and psychological stress continue to be debated, and no data are available from surveys in the African region. In this study, we examine the associations between CVRFs and psychological stress in the Seychelles, a rapidly developing small island state in the African region. A survey was conducted in 1,240 adults aged 25-64 years representative of the Seychelles. Participants were asked to rank psychological stress that they had experienced during the past 12 months in four domains: work, social life, financial situation, and environment around home. CVRFs (high blood pressure, tobacco use, alcohol drinking, and obesity) were assessed using standard procedures. Psychological stress was associated with age, sex, and socioeconomic status. Overall, there were only few consistent associations between psychological stress and CVRFs, adjusting for age, sex, and socioeconomic status. Social stress was associated with smoking, drinking, and obesity, and there were marginal associations between stress at work and drinking, and between financial stress, and smoking and drinking. Psychological stress was not associated with high blood pressure. These findings suggest that psychological stress should be considered in cardiovascular disease prevention and control strategies.

Job Strain and Casual Blood Pressure Distribution: Looking beyond the Adjusted Mean and Taking Gender, Age, and Use of Antihypertensives into Account. Results from ELSA-Brasil

Methodological issues are pointed to as the main sources of inconsistencies in studies about the association between job strain and blood pressure (BP)/hypertension. Our aim was to analyze the relationship between job strain and the whole BP distribution, as well as potential differences by gender, age, and use of antihypertensives. Additionally, we addressed issues relating to the operationalization of the exposure and outcome variables that influence the study of their inter-relations. We evaluated the baseline date of 12,038 participants enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) (2008–2010), a multicenter cohort study of 35–74-year-old civil servants. Job strain was assessed by the Demand-Control-Support Questionnaire. The distribution of casual BP by categories of job strain was compared by a combination of exploratory techniques. Participants were classified into three subgroups (normotensives, medicated hypertensives, and unmedicated hypertensives), and analyses were stratified by gender and age. The relationship between job strain and casual BP varied along the whole outcome distribution. Hypertensive participants had greater differences in casual BP by job strain category, especially medicated hypertensives. Differences in casual BP were also greater for systolic than for diastolic BP and for older participants. No differences were encountered by gender. The exclusion of participants susceptible to misclassification for the exposure and outcome variables increased the differences observed between the categories of low and high job strain. In conclusion, the relationship between job strain and casual BP varied along the whole outcome distribution and by use of antihypertensive drugs, age, and BP parameter evaluated. Misclassification for exposure and outcome variables should be considered in analyses of this topic.

Inhibitory Effects and Mechanisms of Electroacupuncture via Chronically Implanted Electrodes on Stress-Induced Gastric Hypersensitivity in Rats With Neonatal Treatment of Iodoacetamide

BACKGROUND

Stress is considered an independent factor causing and aggravating gastrointestinal symptoms, including visceral pain. The aim of this study was to investigate effects and mechanisms of electroacupuncture (EA) on stress-induced gastric hypersensitivity in rats treated with neonatal iodoacetamide mimicking human functional dyspepsia (FD).

METHODS

Neonatal rats were treated with gavage of 0.2 mL of 0.1% iodoacetamide in 2% sucrose daily for six days starting on tenth day after birth. The control group was given 0.2 mL of 2% sucrose. When the rats were eight weeks old, acute restraint stress was performed on them for 90 min. EA at ST36 (ZuSanLi) was performed during the acute stress or 30 min after the stress. Adrenoceptor blocking drugs (propranolol and phentolamine) were injected intraperitoneally 30 min before acute restraint stress to explore possible sympathetic mechanisms. Visceral-motor responses to gastric distention were assessed by electromyogram (EMG).

RESULTS

1) Stress-induced gastric hypersensitivity was significantly more severe in the FD rats, compared to the control rats. It was blocked by the adrenoceptor antagonists. 2) EA inhibited stress-induced gastric hypersensitivity; the preventive effect of EA (given during stress) was more remarkable than the curative effect (given after stress). Stress resulted in a higher sympathovagal ratio and this was suppressed by EA.

CONCLUSIONS

Rats treated with neonatal iodoacetamide mimicking FD are more vulnerable to stress. Stress-induced gastric hypersensitivity can be prevented or suppressed by EA at ST36 via the restoration of sympathovagal balance.

Mediterranean lifestyle and cardiovascular disease prevention

BACKGROUND

Adherence to a Mediterranean dietary pattern is a well-established protective factor against cardiovascular disease (CVD). However, diet quality is only one aspect of the overall healthy lifestyle adopted by Mediterranean populations. The latter has never been evaluated as a multi-factorial composite lifestyle. Thus, the aim of the present study was to provide a broader picture of the Mediterranean lifestyle and its effects on CVD risk, among elderly individuals.

METHODS

During 2005-2015, 2,749 older (aged 65-100 years) from 21 Mediterranean islands (MEDIS) and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled onto the study. Dietary habits, physical activity status, socio-demographic characteristics, lifestyle parameters (sleep, smoking habits, social life and educational status) and clinical profile aspects were derived through standard procedures.

RESULTS

The overall prevalence of the traditional CVD risk factors were 62.3% for hypertension, 22.3% for diabetes mellitus (type 2) and 47.7% for hypercholesterolemia. The presence of diabetes mellitus was positively predicted by the geriatric depression scale (GDS) [odds ratio (OR) =1.13, 95% confidence interval (CI): 1.02-1.25] and by an urban residential environment (OR =2.57, 95% CI: 1.10-6.06) after adjusting for several confounders. Presence of hypertension was predicted by increasing age (OR =1.07, 95% CI: 1.02-1.12), increasing body mass index (BMI) (OR =1.12, 95% CI: 1.04-1.21), the habit of midday sleep (OR =2.07, 95% CI: 1.07-4.02) and inversely predicted by the frequency of socializing with friends (OR =0.767, 95% CI: 0.616-0.955). The estimated score in the GDS was the only independent positive predictor for the presence of hypercholesterolemia (OR =1.10, 95% CI: 1.01-1.21).

CONCLUSIONS

Lifestyle parameters such as social life, midday sleep (siesta) and residential environment are strongly associated with the presence of CVD risk factors in elderly and should be part of broader CVD prevention strategies to reduce the burden of the disease.

Prevention and Control of Cardiovascular Disease in the Rapidly Changing Economy of China

With one-fifth of the world's total population, China's prevention and control of cardiovascular disease (CVD) may affect the success of worldwide efforts to achieve sustainable CVD reduction. Understanding China's current cardiovascular epidemic requires awareness of the economic development in the past decades. The rapid economic transformations (industrialization, marketization, urbanization, globalization, and informationalization) contributed to the aging demography, unhealthy lifestyles, and environmental changes. The latter have predisposed to increasing cardiovascular risk factors and the CVD pandemic. Rising CVD rates have had a major economic impact, which has challenged the healthcare system and the whole society. With recognition of the importance of health, initial political steps and national actions have been taken to address the CVD epidemic. Looking to the future, we recommend that 4 priorities should be taken: pursue multisectorial government and nongovernment strategies targeting the underlying causes of CVD (the whole-of-government and whole-of-society policy); give priority to prevention; reform the healthcare system to fit the nature of noncommunicable diseases; and conduct research for evidence-based, low-cost, simple, sustainable, and scalable interventions. By pursuing the 4 priorities, the pandemic of CVD and other major noncommunicable diseases in China will be reversed and the global sustainable development goal achieved.

Gender differences in the relationships between psychosocial factors and hypertension

Gender differences in the epidemiology, pathophysiology, clinical manifestations and outcomes of cardiovascular disease are well established but there is still a lack of awareness of this both in the general population and among healthcare providers. In addition to the traditionally recognized cardiovascular risk factors, more recently psychosocial risk factors such as stress, mood disorders, low socioeconomic status and sleep disorders have been linked to cardiovascular diseases and hypertension. Psychosocial factors may have different cardiovascular consequences in men and women; thus further efforts are required to explore pathophysiological mechanisms, to obtain gender-specific data from clinical trials and to translate this knowledge into everyday clinical practice.

Association Between Lifestyle and Hypertension in Patients Referred to Health Care Centers of Ilam City in 2014

INTRODUCTION

Lifestyle is referred to an individual's healthy and unhealthy behaviors that can affect their health statues. The present study aim was association between lifestyle and hypertension in patients referred to healthcare centers of Ilam city in 2014.

MATERIALS & METHODS

This research study was a case-control study. The data were collected through a standard questionnaire of health-promoting lifestyle profile (HPLPII) as well as the researcher's direct visit to the health care centers in the city of Ilam. After the questionnaires were collected and classified, the data were entered into SPSS software and analyzed by descriptive statistics, chi-square tests, T-Tests and logistic regression.

RESULTS

The mean and the standard deviation of the age of the main and the control groups were 57.1 (2.22) and 56.5 (2.99) years old, respectively. 10.9%of the control group and 25.5. % of the cases was smoking cigarettes or hookah. The results of the data analysis showed that the mean scores obtained by the main and the control groups on measures of physical activity, psychological growth, stress and total lifestyleare significantly different, so that the obtained score in the dimensions in patients with hypertension was significantly lower than the score obtained among the healthy individuals.

CONCLUSIONS

According to the results it seems that educational interventions in the field of healthy lifestyle for individuals with hypertension risk can have an effect on controlling this disease and reducing its incidence.
