The Prevalence and Risk Factors of Hypertension among the Urban Population in Southeast Asian Countries: A Systematic Review and Meta-Analysis

Health-care-seeking behaviour in patients with hypertension: experience from a dedicated hypertension centre in Bangladesh

Objective: The study aimed to assess health-seeking behaviour (HSB) and associated factors among hypertensive patients in Bangladesh.Methods: This cross-sectional study was conducted in the Hypertension & Research Centre, Rangpur, Bangladesh, between January 2022 and June 2022. A total of 497 hypertensive adults were recruited consecutively. A pre-tested structured questionnaire was deployed by the research team for data collection. Multivariable logistic regression analysis was used to explore the predictors of HSB.Results: The mean age of the hypertensive patients was 52 ± 11 (SD) years. Most of them were aged between 51 and 60 years (33%), female (55%), came from rural areas (57%), and belonged to middle socioeconomic class (68%). One-fourth of the patients (27%) had chosen informal healthcare providers for their first consultation. Fear of stroke (244, 45%), headache (170, 36%), and neck pain (81, 17%) were the three most common compelling causes of their visit to the hypertension centre. Age (aOR 0.78, 95% CI 0.68 - 0.89), male sex (aOR: 1.79, 95% CI 1.05 - 3.10), living in semi-urban (aOR 4.68, 95% CI 1.45 - 15.10) and rural area (aOR 1.68, 95% CI 1.01 - 2.80), farmers as occupation (aOR: 3.24, 95%CI: 1.31 - 8.06) and belonging to lower social economic class (aOR 4.24, 95% CI 1.68 - 10.69) were predictors of visiting informal providers of hypertensive patient. One-fourth of the hypertensive patients received consultation from informal healthcare providers.Conclusions: Raising awareness among patients and proper referral to specialised hypertension centres could promulgate the patients towards appropriate behaviour.

Machine learning models identify micronutrient intake as predictors of undiagnosed hypertension among rural community-dwelling older adults in Thailand: a cross-sectional study

Objective

To develop a predictive model for undiagnosed hypertension (UHTN) in older adults based on five modifiable factors [eating behaviors, emotion, exercise, stopping smoking, and stopping drinking alcohol (3E2S) using machine learning (ML) algorithms.

Methods

The supervised ML models [random forest (RF), support vector machine (SVM), and extreme gradient boosting (XGB)] with SHapley Additive exPlanations (SHAP) prioritization and conventional statistics (χ2 and binary logistic regression) were employed to predict UHTN from 5,288 health records of older adults from ten primary care hospitals in Thailand.

Results

The χ2 analyses showed that age and eating behavior were the predicting features of UHTN occurrence. The binary logistic regression revealed that taking food supplements/vitamins, using seasoning powder, and eating bean products were related to normotensive and hypertensive classifications. The RF, XGB, and SVM accuracy were 0.90, 0.89, and 0.57, respectively. The SHAP identified the importance of salt intake and food/vitamin supplements. Vitamin B6, B12, and selenium in the UHTN were lower than in the normotensive group.

Conclusion

ML indicates that salt intake, soybean consumption, and food/vitamin supplements are primary factors for UHTN classification in older adults.

Air Pollution and Blood Pressure: Evidence From Indonesia

Indonesia faces significant air quality issues due to multiple emissions sources, including rapid urbanization and peatland fires associated with agricultural land management. Limited prior research has estimated the episodic shock of intense fires on morbidity and mortality in Indonesia but has largely ignored the impact of poor air quality throughout the year on biomarkers of cardiovascular disease risk. We conducted a cross-sectional study of the association between particulate matter less than 2.5 microns in diameter (PM2.5) and blood pressure. Blood pressure measurements were obtained from the fifth wave of the Indonesian Family Life Survey (IFLS5), an ongoing population-based socioeconomic and health survey. We used the GEOS-Chem chemical transport model to simulate daily PM2.5 concentrations at 0.5° × 0.625° resolution across the IFLS domain. We assessed the association between PM2.5 and diastolic and systolic blood pressure, using mixed effects models with random intercepts for regency/municipality and household and adjusted for individual covariates. An interquartile range increase in monthly PM2.5 exposure was associated with a 0.234 (95% CI: 0.003, 0.464) higher diastolic blood pressure, with a greater association seen in participants age 65 and over (1.16 [95% CI: 0.24, 2.08]). For the same exposure metric, there was a 1.90 (95% CI: 0.43, 3.37) higher systolic blood pressure in participants 65 and older. Our assessment of fire-specific PM2.5 yielded null results, potentially due to the timing and locations of health data collection. To our knowledge, this is the first study to provide evidence for an association between PM2.5 and blood pressure in Indonesia.

The relationship between liver enzymes, prehypertension and hypertension in the Azar cohort population

BACKGROUND

The incidence of hypertension (HTN) as a worldwide health problem is rising rapidly. Early identification and management of pre-HTN before HTN development can help reduce its related complications. We evaluated the relationship between liver enzymes levels and pre-HTN/HTN in the Azar cohort population.

METHOD

This cross-sectional study was based on data from the large Azar cohort study and a total of 14,184 participants were included. Pre-HTN and HTN were defined based on the American Heart Association guideline. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) levels were measured by Pars Azmoon kits. The relationship between pre-HTN/HTN and liver enzyme levels was evaluated by logistic regression.

RESULTS

Of 14,184 participants, 5.7% and 39.6% had pre-HTN and HTN, respectively. In the adjusted model, AST levels of 19-23 IU/l were associated with an elevated risk of pre-HTN (OR [95% CI]: 1.24 [1.04-1.48]). A dose-response increase was seen in pre-HTN in relation to ALT, with the highest OR in the third tertile (1.34 [1.09-1.63]). The odds of pre-HTN also increased with GGT in the third tertile (1.25[1.03-1.52]). In addition, the odds of HTN increased with increased levels of AST, ALT, ALP, and GGT, such that the highest ORs were recorded in the third tertile (OR 1.22 [1.09-1.37], 1.51 [1.35-1.70], 1.19 [1.07-1.34], and 1.68 [1.49-1.89], respectively). Among these enzymes, GGT had the highest OR regarding HTN.

CONCLUSION

This study indicates that AST, ALT, ALP and GGT levels were associated with pre-HTN (except for ALP) and HTN, independent of known risk factors. Hence, it may be possible to use liver enzymes to predict the incidence of pre-HTN and HTN, empowering primary care providers to make the necessary interventions promptly.

Safety classification of herbal medicine use among hypertensive patients: a systematic review and meta-analysis

Background

The use of herbal medicines (HMs) for the treatment of hypertension (HTN) is increasing globally, but research on the potential adverse effects and safety of HMs in HTN patients is limited. Therefore, this systematic review and meta-analysis aim to determine the global prevalence of HM usage among HTN patients and assess the safety of identified herbs based on current scientific evidence.

Methods

The PubMed/MEDLINE, EMBASE (Ovid), and Cumulated Index to Nursing and Allied Health Literature (CINAHL) databases were searched for cross-sectional studies on the use of HM among HTN patients. Our review includes studies published in English up to the year 2023. After extracting and appraising the data from the studies, a meta-analysis was conducted using the Stata version 16.0 to estimate the pooled prevalence of HM use in patients with HTN (PROSPERO: CRD42023405537). The safety classification of the identified HM was done based on the existing scientific literature.

Results

This study analyzed 37 cross-sectional studies from 21 countries and found that 37.8% of HTN patients used HM to manage their health. The prevalence of HM use varied significantly based on publication year and geographical region. Among the 71 identified herbs, Allium sativum L., Hibiscus sabdariffa L., and Olea europaea L. were the most commonly used. However, four herbs were identified as contraindicated, 50 herbs required caution, and only 11 herbs were considered safe for use.

Conclusion

The study highlights the potential risks of toxicities and adverse effects associated with HM use in the treatment of HTN. Ensuring patient safety involves using safe HMs in appropriate doses and avoiding contraindicated HMs. Future research should focus on identifying commonly used herbs, especially in resource-limited countries with poor HTN management, and additional clinical research is required to assess the toxicity and safety of commonly used HMs.

Health literacy and high blood pressure among Myanmar migrant workers in Northeastern Thailand

Hypertension, related to serious consequences unless diagnosed and treated, is a global concern, also affecting migrant workers. Due to the high prevalence of hypertension among migrant workers in Thailand, the influences of health literacy and other factors on blood pressure were needed to explore among Myanmar migrant workers in Northeastern Thailand. Hence, this study aimed to identify the prevalence of high blood pressure (HBP), its association with health literacy and other factors among Myanmar migrant workers in Northeastern Thailand. A cross-sectional analytical study was conducted in Northeastern Thailand. A multistage sampling procedure was applied. Data was gathered through interviews utilizing validated and reliable structured questionnaire. Descriptive statistics and inferential statistics with multiple logistic regression were used. Among 406 participants, about 60% were male and about 70% of them were married. The prevalence of overall HBP was 63.3% (95% CI: 58.49-67.86), 52% in females and 71.86% in males. Participants with limited health literacy were 79% more likely to have HBP than those with excellent and adequate health literacy (AOR = 1.79, 95% CI: 1.13-2.84). Other factors substantially linked with having HBP were being male gender (AOR = 4.68, 95% CI: 2.81-7.78), being overweight (AOR = 2.23, 95% CI: 1.18-4.23), being obese (AOR = 5.69, 95% CI: 2.96-10.96), not having health insurance (AOR = 2.01, 95% CI: 1.11-3.66), staying in Thailand for more than 48 months (AOR = 2.4, 95% CI: 1.48-3.9), and having family history of hypertension (AOR = 2.07, 95% CI: 1.28-3.35). In conclusion, more than half of Myanmar migrant workers had HBP. Factors associated with HBP were limited health literacy, male gender, overnutrition, lack of health insurance, longer duration of stay in Thailand and having family history of hypertension. Therefore, there is a need for a multifaceted strategy to prevent hypertension and its consequences by promoting health literacy as well as by enhancing good behavioural practice among this community.

Efficacy and safety of esaxerenone (CS-3150) in primary hypertension: a meta-analysis

This study aimed to assess the efficacy and safety of esaxerenone (CS-3150) in treating primary hypertension. PubMed (Medline), Cochrane Central Register of Controlled Trials (CENTRAL), and Embase databases were searched for articles published until April 18, 2023. The outcomes included were diastolic blood pressure (DBP), systolic blood pressure (SBP), 24 h DBP, 24 h SBP, and adverse events. The meta-analysis was conducted using RevMan 5.3. This study included three trials. CS-3150 5 mg had a greater effect on lowering the SBP, DBP, 24 h SBP, and 24 h DBP than either CS-3150 2.5 mg or eplerenone 50 mg. In contrast, CS-3150 2.5 mg and eplerenone 50 mg showed no significant difference in lowering DBP, SBP, 24 h DBP, and 24 h SBP. Moreover, adverse events occurred at comparable rates in the three groups. CS-3150 (especially CS-3150 5 mg) is an effective and safe treatment for primary hypertension; which can reduce blood pressure and alleviate hypertensive symptoms.

A Focused Group Perspective of Risk Factors for Hypertension Among Middle-Aged Adults in Rural Areas of Anambra State, Nigeria

PURPOSE

Recent records by the World Health Organization show that hypertension is more prevalent in Africa than in other parts of the world, and remains the foremost common risk factor for cardiovascular-related diseases, stroke, renal diseases, and death. However, little is known about the risk factors for hypertension by people from rural areas, especially among middle-aged adults. Therefore, the study examined the knowledge of the risk factors for hypertension among middle-aged adults in rural areas of Anambra state, Nigeria.

MATERIALS, AND METHOD

Focus group discussions were used to collect data from 40 middle-aged adults (20 males and 20 females). Two key themes stood out from the data collection guides. These are "awareness of hypertension and its' symptoms" and "knowledge of risk factors of hypertension".

RESULTS

The findings showed that the participants were aware of hypertension but lacked in-depth knowledge of the risk factors for the disease. Most participants did not believe that intake of certain foods like starchy foods and excess alcohol consumption could lead to one being hypertensive.

DISCUSSION AND CONCLUSION

There is a need for social workers to sensitize and enlighten the middle-aged adults in the study area on the risk factors for the disease.

Self-care behavior among adult patients with hypertension in Padang, West Sumatra, Indonesia: A cross-sectional study

Background

Self-care behavior is crucial in preventing chronic diseases, such as hypertension, which has become highly prevalent in Indonesia. Hypertension, often referred to as the "silent killer" due to its asymptomatic nature, can easily go unnoticed. Neglecting its treatment can lead to severe complications, including heart disease, heart failure, and stroke. Despite adults with hypertension feeling well, embracing self-care behavior, including making healthy lifestyle choices, disease management, and enhancing life quality, remains essential.

Objective

This study aimed to describe the self-care behavior of adult patients with hypertension in Indonesia.

Methods

A cross-sectional study design was employed, involving 270 participants selected through consecutive sampling. Data were collected between 15 March and 4 April 2023, using the Hypertension Blood Pressure Self Care Profile (HBP-SCP) questionnaire in six public healthcare centers in Padang City, West Sumatra, Indonesia. The data were analyzed using descriptive analysis, Mann-Whitney, and Kruskal-Wallis tests.

Results

The self-care behavior among adult patients with hypertension was at a moderate level (Mean = 49.78, SD = 6.64), and it had significant differences according to ethnicity (p = 0.041), marital status (p = 0.017), and body mass index (p = 0.008).

Conclusion

The findings highlight the influence of diverse ethnic backgrounds, various marital statuses, and differing body mass index levels, which may lead to distinct approaches to managing hypertension. These results offer valuable insights for nurses and other healthcare professionals to develop comprehensive strategies to enhance self-care among adult patients with hypertension.

Factors Associated with Hypertension Among Adults: A Cross-Sectional Analysis of the Indonesian Family Life Survey

Purpose

Hypertension (HTN) poses a significant health risk for Indonesia's large population. Underlying factors contributing to this disease are not fully understood at a national level. Therefore, this study aimed to evaluate factors associated with HTN in Indonesia.

Patients and Methods

This study used data from the Indonesian Family Life Survey-5, a 2014 national cross-sectional population-based survey of individuals aged 15 years and older. The mean arterial pressure (MAP) value was determined from three blood pressure measurements taken by trained nurses using Omron digital sphygmomanometers. The respondent was classified as hypertensive when the MAP value was at least 100. The study summarised the socio-demographic factors (age, gender, marital status, ethnicity and occupation status) and lifestyle habits (smoking, sleep quality, physical activity) with descriptive statistics. The potential associations between these factors and HTN were assessed using logistic regression analysis. The results were reported in terms of odds ratios (OR) with a 95% confidence interval (CI).

Results

The study included 32,670 respondents; 31.2% of them had HTN. Factors that were more likely associated with HTN were being <65 years old, being married (OR 1.257, 95% CI 1.170-1.352) and being smoker (OR 1.297, 95% CI 1.198-1.404), while being male (OR 0.677, 95% CI: 0.625-0.733) and doing no physical activity (OR 0.870, 95% CI: 0.813-0.930) were less likely to be associated with HTN.

Conclusion

This study indicates that there are associations between certain socio-demographic factors and lifestyle habits with HTN in Indonesia. This information may help policymakers and healthcare providers to develop effective strategies in order to control HTN in Indonesia, thereby improving the overall health and well-being of the population.

Prevalence and Factors Associated with Prehypertension and Hypertension Among Adults: Baseline Findings of PURE Malaysia Cohort Study

Background

Although prehypertension and hypertension can be detected at the primary healthcare level and low-cost treatments can effectively control its complications, hypertension is still the world's leading preventable risk factor. Therefore, the present study aimed to determine its prevalence and its risk factors among Malaysian adults.

Methods

A cross-sectional study involving 7585 adults was performed covering the rural and urban areas. Respondents with systolic blood pressure (SBP) of 120-139 mmHg and/or diastolic blood pressure (DBP) of 80-89 mmHg were categorized as prehypertensive, and hypertensive categorization was used for respondents with an SBP of ≥140 mmHg and/or DBP of ≥90 mmHg.

Results

Respondents reported to have prehypertension and hypertension were 40.7% and 38.0%, respectively. Those residing in a rural area, older age, male, family history of hypertension, and overweight or obese were associated with higher odds of prehypertension and hypertension. Unique to hypertension, the factors included low educational level (AOR: 1.349; 95% CI: 1.146, 1.588), unemployment (1.350; 1.16, 1.572), comorbidity of diabetes (1.474; 1.178, 1.844), and inadequate fruit consumption (1.253; 1.094, 1.436).

Conclusions

As the prehypertensive state may affect the prevalence of hypertension, proactive strategies are needed to increase early detection of the disease among specific group of those residing in a rural area, older age, male, family history of hypertension, and overweight or obese.

Investigating the relationship between liver enzymes and incidence of hypertension: A population-based cohort study in Kharameh, a city in the South of Iran

Background and Aims

Hypertension and abnormal liver enzymes are common health issues that frequently coexist, and recent research has suggested a possible association between them, warranting further investigation. Therefore, the aim of this study is to explore the relationship between liver enzymes and hypertension.

Methods

This prospective cohort study utilized data from the Kharameh cohort study, which is a branch of the Prospective Epidemiological Studies in Iran (PERSIAN) database. The study included 7710 participants aged between 40 and 70 years. Hypertension was defined in accordance with the European guidelines for hypertension management, and the association between liver enzymes and hypertension was modeled and predicted using Firth logistic regression.

Results

This study investigated the association between liver enzymes and hypertension risk in a cohort of 7710 individuals aged 40-70 years. The results showed that higher levels of alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), and alkaline phosphatase (ALP) were associated with an increased risk of hypertension, and this relationship remained significant even after adjusting for potential confounding factors. Additionally, separate analyses within age subgroups revealed a significant association between ALP concentration and high blood pressure in certain age ranges.

Conclusion

The study demonstrated a significant association between high levels of ALT, GGT, and ALP and an increased risk of hypertension, regardless of other risk factors. These results suggest that monitoring liver enzymes, specifically ALT, GGT, and ALP, could serve as a useful tool to predict hypertension risk and identify individuals who could benefit from early intervention. Overall, these findings underscore the importance of monitoring liver function in preventing and managing hypertension.

Endothelial dysfunction, platelet hyperactivity, hypertension, and the metabolic syndrome: molecular insights and combating strategies

Metabolic syndrome (MetS) is a multifaceted condition that increases the possibility of developing atherosclerotic cardiovascular disease. MetS includes obesity, hypertension, dyslipidemia, hyperglycemia, endothelial dysfunction, and platelet hyperactivity. There is a concerning rise in the occurrence and frequency of MetS globally. The rising incidence and severity of MetS need a proactive, multipronged strategy for identifying and treating those affected. For many MetS patients, achieving recommended goals for healthy fat intake, blood pressure control, and blood glucose management may require a combination of medicine therapy, lifestyles, nutraceuticals, and others. However, it is essential to note that lifestyle modification should be the first-line therapy for MetS. In addition, MetS requires pharmacological, nutraceutical, or other interventions. This review aimed to bring together the etiology, molecular mechanisms, and dietary strategies to combat hypertension, endothelial dysfunction, and platelet dysfunction in individuals with MetS.

Blood Parameter Profiles and Their Clinical Implications in Hypertensive Patients: A Retrospective Chart Review

Introduction Hypertension (HTN) is a chronic condition that serves as a major risk factor for cardiovascular diseases, leading to increased mortality and morbidity. It is a frequent modifiable illness affecting global health, resulting in catastrophic fatalities and morbidity. Aim This study aims to investigate blood parameter profiles and their clinical implications in hypertensive patients at the Prince Faisal bin Khalid Cardiac Center in Abha, Saudi Arabia. Methods Utilizing retrospective data from 121 patients at the Prince Faisal bin Khalid Cardiac Center in Abha, Saudi Arabia. The hematological parameter examined were hemoglobin (HB), platelets, hematocrit (HCT), calcium, phosphorus, sodium, potassium, urea, creatinine, and uric acid. The SPSS version 28 software was used for data analysis. Results Significant correlations between various hematological parameters were found in the results, pointing to potential connections between kidney function, the production of blood cells, and electrolyte balance in hypertensive patients. The results align with earlier studies carried out in the area and offer insightful information for clinicians and researchers interested in managing HTN and its complications. Conclusion The study emphasized the significance of considering hypertensive patients' age, gender, and lifestyle when interpreting their blood parameter profiles. The findings imply that a thorough comprehension of these blood parameter values and their potential effects on HTN is necessary for effectively managing HTN in this population. This study on the blood parameter profiles in hypertensive patients in Saudi Arabia provides the relationships between various hematological parameter and their clinical implications. These findings should be considered when creating targeted interventions and strategies to address the specific requirements and difficulties of managing HTN and its associated complications in this population. More research is required to comprehend the underlying reasons for the observed variations in hematological parameter profiles and their effects on the management of HTN.

The prevalence, disability-adjusted life years, and mortality of hypertensive heart disease and its attributable risk factors: results from the Global Burden Disease study 2019

Introduction

No survey has evaluated hypertensive heart disease (HHD) burden with statistics from the Risk Factors Study, Injuries, and the Global Burden of Diseases (GBD) 2019.

Material and methods

The evaluated annual percentage changes (EAPCs) were obtained to assess the trend in prevalence standardized by age, mortality rates standardized by age, and DALYs standardized by age between 1990 and 2019. We also evaluated the contribution of risk factors to HHD-associated DALYs and mortality.

Results

Between 1990 and 2019, the worldwide prevalence rate standardized by age increased (EAPC = 0.17; 95% confidence interval (CI) 0.15 to 0.18), but the death rate standardized by age (EAPC = -0.74; 95% CI: -0.91 to -0.57) and DALYs standardized by age rate decreased (EAPC = -1.02; 95% CI: -1.18 to -0.86). The prevalence rate of HHD standardized by age increased the most in the high-middle areas of SDI (EAPC = 0.43). The biggest increases in the prevalence rate standardized by age were in Andean Latin America (EAPC = 0.43), Western Sub-Saharan Africa (EAPC = 0.30), and the Middle East and North Africa (EAPC = 0.24). The largest decrease in mortality that could be attributed to rate and DALYs in both sexes between 1990 and 2019 was consistent with a high BMI.

Conclusion

The worldwide prevalence rate standardized by age increased during 1990-2019, especially in Andean Latin America, North Africa, the Middle East, and Western Sub-Saharan Africa. Future HHD prevention tactics should be focused on males, high-risk areas, and control of high BMI.

A systematic review and meta-analysis of the prevalence of dyslipidaemia among adults in Malaysia

Dyslipidaemia is an established cardiovascular risk factor. This study aimed to determine the pooled prevalence of dyslipidaemia in Malaysian adults. A systematic review and meta-analysis of all cross-sectional, longitudinal observational studies which reported the prevalence of elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), and reduced high-density lipoprotein cholesterol (HDL-c) in adults 18 years old and older, was conducted. A comprehensive search of PubMed and Cochrane Central Register of Controlled Trials (which included Medline, EMBASE and major trial registers) from inception to October 18, 2022, was performed. Risk-of-bias was evaluated using the Johanna-Briggs Institute Prevalence Critical Appraisal Tool, while certainty of evidence was assessed using an adapted version of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Random-effects meta-analyses were performed using MetaXL. This report follows the PRISMA reporting guidelines. The protocol was registered with PROSPERO (CRD42020200281). 26 556 studies were retrieved and 7 941 were shortlisted initially. From this, 70 Malaysian studies plus two studies from citation searching were shortlisted; 46 were excluded, and 26 were included in the review (n = 50 001). The pooled prevalence of elevated TC (≥ 5.2 mmol/L), elevated LDL-c (≥ 2.6 mmol/L), elevated TG (≥ 1.7 mmol/L), and low HDL-c (< 1.0 mmol/L in men and < 1.3 mmol/L in women) were 52% (95% CI 32-71%, I2 = 100%), 73% (95% CI 50-92%, I2 = 100%), 36% (95% CI 32-40%, I2 = 96%), and 40% (95% CI 25-55%, I2 = 99%), respectively. This review found that the prevalence of all dyslipidaemia subtypes is high in Malaysian adults. Ongoing efforts to reduce cardiovascular diseases in Malaysia should integrate effective detection and treatment of dyslipidaemia.

Associated Factors of Tophaceous Gout: A Study Involving 20 Primary Care Clinics in an Urbanized State in Malaysia

Objectives

Gout is a treatable disease. A complication of untreated or poorly-controlled gout is tophi formation. We conducted this study to investigate the associated factors of tophaceous gout among patients who attended 20 primary care clinics in Selangor, an urbanized state in Malaysia.

Methods

We conducted a cross-sectional study from July to October 2019 that included all patients with gout who attended the clinics. Data on clinical demographics and laboratory results were collected. Comparison between tophaceous and non-tophaceous groups was performed using descriptive analysis.

Results

A total of 421 patients with gout were involved in this study, 83 (19.7%) patients had visible tophi and were categorized into the tophaceous group, while the other 338 (80.3%) patients were categorized into the non-tophaceous group. The majority of patients were male with a mean age of 57.6±12.8 years. Three factors found to be significantly associated with tophaceous gout were age at symptom onset [tophaceous (45.6±13.3 years) vs. non-tophaceous (49.7±13.9 years), p = 0.026], mean disease duration of gout [tophaceous (105.2±92.6 months) vs. non-tophaceous (77.6±88.6 months), p = 0.013], and baseline serum uric acid level [tophaceous (622.3±129.1 µmol/L) vs. non-tophaceous (582.6±102.3 µmol/L), p = 0.021].

Conclusions

Tophaceous gout is associated with longer disease duration, higher baseline serum uric acid level, and younger age at symptoms onset. Hence, early initiation of urate-lowering therapy with a treat-to-target approach is crucial to prevent tophi formation.

The prevalence and influencing factors of coexisting prediabetes and prehypertension among Bangladeshi adults

BACKGROUND

Early detection of diabetes and hypertension is helpful to prevent and/or delay the onset of these diseases through proper interventions. Therefore, it is a prerequisite to know the prevalence of prediabetes and prehypertension and the factors associated with these conditions but people from developing countries including Bangladesh often remain undiagnosed and unaware of these conditions. In this study we investigate the prevalence of prediabetes and prehypertension and their associated factors in Bangladesh using nationally representative data.

METHOD

We used nationally representative Bangladesh Demographic and Health Survey (BDHS) 2017-18 survey data, which included a total sample of 14,704 adults aged 18 years and more from whom blood pressure and fasting plasma glucose were collected. Chi-square test was used to examine the differences between sociodemographic and outcome variables. The univariate and multivariate logistic regression was performed to identify the factors associated with prediabetes and prehypertension.

RESULTS

Overall, the prevalence of prediabetes and prehypertension was 8.6% with 14% of the sampled population having from prediabetes and prehypertension separately. Among the prediabetic and prehypertensive participants, one-fourth of the participant were from the richest families and around one-third were overweight/obese, while more than fifty percent had normal Body Mass Index (BMI) and completed secondary and higher education. In the univariate analysis, the richest wealth status (UOR 3.3, 95% CI: 2.46 -4.35) and overweight/obesity (UOR 3.2, 95% CI: 2.62-3.85) are the highest predictors for prediabetes and prehypertension. After adjusting the other variables, overweight/obesity remains the largest predictor for prediabetes and prehypertension (AOR:2.5, 95% CI:2.05-3.05). Further, people aged 31 and above and from the richest family had around 2 times and 1.8 times higher risk of being prediabetic and prehypertensive compared to the younger age people (18-30 years) and the poorest family (respectively).

CONCLUSION

The coexistence of prediabetes and prehypertension is an early sign of a greater burden of noncommunicable diseases (NCDs) in the near future for Bangladesh. To reduce the higher burden of NCDs, our findings call for a multisectoral approach to identify the precondition of NCDs with particular attention to maintaining body weight.

Comprehensive effects of lifestyle reform, adherence, and related factors on hypertension control: A review

Despite the effectiveness of currently available antihypertensive medications, there is still a need for new treatment strategies that are more effective in certain groups of hypertensive and for additional resources to combat hypertension. However, medication non-adherence was previously recognized as a major problem in the treatment of hypertension. The mechanisms behind the positive impacts of lifestyle changes might occur in different ways. In comparison with other studies, the efficacy and effectiveness of lifestyle modifications and antihypertensive pharmaceutical treatment for the prevention and control of hypertension and concomitant cardiovascular disease have been demonstrated in randomized controlled trials. However, in this review, the attitudinal lifestyle modifications and barriers to blood pressure control were elaborated on. An effective method for reducing blood pressure (BP) and preventing cardiovascular events with antihypertensive medications has been outlined. Maintaining healthy lifestyle factors (body mass index, diet, smoking, alcohol consumption, sodium excretion, and sedentary behavior) could lower systolic blood pressure BP by 3.5 mm Hg and reduce the risk of cardiovascular disease (CVD) by about 30%, regardless of genetic susceptibility to hypertension. Conducting a lifestyle intervention using health education could improve lifestyle factors, such as reducing salt, sodium, and fat intake, changing eating habits to include more fruits and vegetables, not smoking, consuming less alcohol, exercising regularly, maintaining healthy body weight, and minimizing stressful conditions. Each behavior could affect BP by modulating visceral fat accumulation, insulin resistance, the renin-angiotensin-aldosterone system, vascular endothelial function, oxidative stress, inflammation, and autonomic function. Evidence of the joint effect of antihypertensive medications and lifestyle reforms suggests a pathway to reduce hypertension.

Two Novel Angiotensin I-Converting Enzyme (ACE) Inhibitory Peptides from Rice (Oryza sativa L.) Bran Protein

To realize the high-value utilization of rice byproducts, the rice bran protein hydrolysate was separated and purified by ultrafiltration and reversed-phase high-performance liquid chromatography (RP-HPLC), then the sequences of peptides were identified by liquid chromatography with tandem mass spectrometry (LC-MS/MS), and their molecular docking analysis and activities in vitro and in the cell were carried out. Two novel peptides FDGSPVGY (840.3654 Da) and VFDGVLRPGQ (1086.582 Da) were obtained with IC₅₀ values of 0.079 mg/mL (94.05 μM) and 0.093 mg/mL (85.59 μM) on angiotensin I-converting enzyme (ACE) inhibitory activity in vitro, respectively. Molecular docking results showed that two peptides interacted with ACE receptor protein through hydrogen bonding, hydrophobic interactions, etc. Through the EA.hy926 cells, it was found that FDGSPVGY and VFDGVLRPGQ could promote the release of nitric oxide (NO) and reduce the content of ET-1 to achieve the effect of antihypertension. In conclusion, the peptides from rice bran protein exhibited significant antihypertension activity and may be expected to realize the high-value utilization of rice byproducts.

Genetic contribution between APE1 variants in polycystic ovarian syndrome

Introduction

Polycystic Ovarian Syndrome (PCOS) has been identified as a gynecological, hormonal, and metabolic condition in women of reproductive age. Genetic studies can contribute to understand the pathogenesis of PCOS; which can be beneficial in early diagnosis and long-term management of the disease. Apurinic/apyrimidinic endonuclease 1 (APE1) has been related in the literature to polycystic ovarian syndrome.

Aim

The purpose of this study was to investigate the effects of -656 T > G and 1349 T > G single nucleotide polymorphisms (SNPs) in the APE1 gene in Saudi women with PCOS.

Methods

This study includes 100 PCOS women and 100 healthy controls were genotyped for -656 T > G and 1349 T > G SNPs using PCR-RFLP method. Serum sample was used for FBG and lipid profile tests. The obtained biochemical and genotypes data were entered into Excel and utilized for statistical analysis.

Results

Clinical data presented in Table 1 was used to calculate the t-tests between PCOS and control subjects and results indicate age, weight, BMI, TG, LDLC and PCOS family history was associated (p < 0.0001). Genotype and allele frequencies showed the negative association in -656 T > G SNP (GG vs TT: OR-1.15 (0.61-2.17); p = 0.65 and GG + TG vs TT: OR-1.17 (0.67-2.04); p = 0.57) and positive association in 1349 T > G SNP (GG vs TT: OR-3.52 (1.48-8.36); p = 0.003 and GG + TG vs TT: OR-2.84 (1.27-6.31); p = 0.008) in APE1 gene. Anova analysis was not associated with any one of the involved parameters (p > 0.05).

Conclusion

This study found that the 1349 T > G SNP was related with PCOS in Saudi women. However, the -656SNP had no favorable effect on the APE1 gene.

Socioeconomic disparities in the burden of hypertension among Indonesian adults - a multilevel analysis

Background

Hypertension remains a problem of public health across various socioeconomic groups, despite its high prevalence. However, few studies account for geographical variation in examining socioeconomic inequalities and hypertension in Indonesia.

Objective

To investigate the burden of hypertension in Indonesia based on prevalence, awareness, treatment, and control of hypertension among adults; and assess whether or not the burdens vary according to geographical variation and socioeconomic status

Methods

In Wave 5 of the Indonesian Family Life Survey in 2015, 32,034 individuals aged 15 and over participated in the study. Concentration Curves (CC) and Concentration Indexes (CI) were used to analyse socioeconomic inequality. We used multilevel logistic regression to assess biological, geographical variation, and socioeconomic factors associated with the burden of hypertension, adjusting for potential covariates.

Results

The prevalence of hypertension in Indonesia was 26.1%, and only 26.9% of those with hypertension were aware of their condition. Approximately 22.5% of hypertensive patients received treatment, but only 28.2% had controlled blood pressure and reached the therapeutic goal. Low socioeconomic groups were more prone to hypertension (CI = −0.047 in urban and CI = −0.075 in rural). In contrast, awareness, treatment, and control of hypertension were more concentrated in higher socioeconomic groups.

Conclusions

The high prevalence of hypertension, low awareness of the condition, poor compliance with treatment, and poor control of the condition, as well as the existing socioeconomic inequality, make this a significant determinant of public health issue in Indonesia. There is a need for effective programs for the prevention of hypertension and better management of hypertensive patients.

Self-Care Management for Hypertension in Southeast Asia: A Scoping Review

Background

Self-care practices such as lifestyle modifications in diet, exercise, and stress management are effective in reducing the incidence of and enhancing better management of hypertension. However, little is known about the self-care management practices of people with hypertension in Southeast Asia (SEA) countries where the prevalence of hypertension is sharply increasing.

Methods

A scoping review of research and grey literature (2006-2021) was performed using Scoping Review Frameworks by Arkey and O'Malley. For the research literature, ten databases were searched followed by a manual search of the reference lists of relevant topical papers. Criteria for inclusion included both qualitative and quantitative primary data studies, focused on adult (18 years and over) hypertensive patients, self-care management methods, conducted in SEA. The study protocol has been registered at Open Science Framework (https://osf.io/s4nvk/).

Results

Out of 1667 studies examined, there were 57 studies that met criteria and were included in this review. Results indicate a paucity of relevant literature. Moreover, most studies reviewed showed an incident rate of 50% or more incidence of behavioural risk factors in people diagnosed with hypertension, including overweight/obesity, poor physical exercise, poor/low-quality dietary intake, and not adhering to medication. Few studies indicated adequate traditional self-care practice among SEA hypertension populations. Use of a non-prescription herbal as the medication is identified in some studies. Several reviewed articles indicated that there is individual variation in the facilitators and barriers to implementing self-care practices and we put it into a working framework. The facilitators and barriers are relevant to personal choice (internal factors) or to the environment or context (external factors).

Conclusion

Enhancing self-care management of hypertension in SEA may require a multi-focused approach including targeting personal choice as well as external factors such as cultural relevance, environment, and resources.

Comparison of measured blood pressure levels, hypertension history, oral diseases, and associated factors among Thai dental patients

PURPOSE

To compare blood pressure (BP), hypertension (HT) history, oral diseases, and potentially associated factors among dental patients in Thailand and explore the associations among them.

METHODS

This study included 709 patients. Demographic data, BP levels, oral diseases, xerostomia, anxiety, depression, and associated factors were evaluated.

RESULTS

One-third of the patients were male; patients with a history of HT were older than those without (P < 0.001). In total, 53 (7.5%) had such a history, and HT was controlled in 29 (54.7%) of them. Patients with possible HT (BP ≥140/90 mmHg; 94 in total, 13.3%) were five times more likely to have a definitive diagnosis of HT than those without possible HT (odd ratio [OR] = 4.95; 95% confidence interval [CI]: 2.76-8.87; P < 0.001). They also had an increased tendency to be taking antidyslipidemic (OR = 5.54; 95% CI: 2.90-10.60; P = 0.001) or antidiabetic (OR = 4.80; 95% CI: 1.91-12.08; P = 0.001) drugs. Male sex (ß = 0.156, P < 0.001), higher age (ß = 0.299, P < 0.001), higher body mass index (ß = 0.410, P < 0.001), and periapical tissue diseases (ß = 0.073, P = 0.019) were significantly associated with elevated systolic BP. Severe periodontitis (ß = 0.081, P = 0.023) and a comparable association pattern with systolic BP were related to diastolic BP. Multivariate analysis revealed no significant association between BP and tooth loss, xerostomia, smoking, education level, anxiety, or depression.

CONCLUSION

Dentists play an essential role in screening for undiagnosed and uncontrolled HT. Significant associations were noted between oral inflammatory diseases and high BP.

Evaluation of Relationship between Serum Liver Enzymes and Hypertension: A Cross-Sectional Study Based on Data from Rafsanjan Cohort Study

Background. Hypertension as a major risk factor for cardiovascular diseases is among the leading causes of death worldwide. The relationship between elevated serum levels of liver enzymes and hypertension has been reported in limited studies, and to the best of our knowledge, there are no previous reports in the literature on this issue in the southeast of Iran. Our investigation aimed at evaluating the relation between ALT, AST, GGT, and ALP with hypertension in the Rafsanjan Cohort Study, a city in Kerman Province, Iran. Methods. In this cross-sectional study, we used data obtained from the Rafsanjan Cohort Study (RCS), as a part of the prospective epidemiological research studies in Iran (PERSIAN). The association of the liver enzymes levels with hypertension was investigated using the multivariable logistic regression models. Results. Among 9930 participants, the mean age (±SD) was 49.94 (±9.56) years, and 46.56% were men. The odds of abnormal blood pressure significantly increased along with the higher levels of ALT, GGT, and ALP which remained significant only for ALP after adjustment for all confounding variables in both males and females (OR in males: 1.36, 95% CI = 1.09–1.69, OR in females: 1.25, 95% CI = 1.01–1.54). In subjects with normal levels of ALT, AST, GGT, and ALP, dose-response increases were observed for abnormal blood pressure in both genders. Finally, we found that, among liver enzymes, only elevated ALP was significantly correlated with the odds of stage 1 hypertension and stage 2 hypertension for both genders. Conclusions. In subjects with normal levels of ALT, AST, GGT, and ALP, dose-response increases were observed for abnormal blood pressure in both genders. Increased serum ALP activity was positively associated with increased odds of hypertension in males and females. Therefore, increased ALP could be an early indicator of hypertension.

Prevalence and Risk Factors for Hypertension among Myanmar Migrant Workers in Thailand

Background: Non-communicable diseases (NCDs) are showing an increasing trend worldwide, and the COVID-19 pandemic may interrupt or delay NCD care, the leading cause of mortality in Thailand, which is hosting 2–3 million migrant workers. The transition of epidemiological risk factors, limited access to health-promoting activities, and pandemic containment measures may adversely impact NCD risks. Therefore, hypertension and associated risk factors were determined among registered Myanmar migrant workers in Thailand. Methods: A cross-sectional survey with structured questionnaires was conducted in Thailand in 2017. Having hypertension was analyzed as a dependent variable, and the associated risk factors were explored by binary logistic regression analysis. Results: A total of 414 participants with a mean age of 29.45 ± 9.03 years were included, and 27.8 percent of the study participants were hypertensive, which was a rate higher than that in their host country (24.7%) and country of origin (26.4%). An older age, being male, current alcohol drinking, and being overweight and obese with reference to the body mass index (BMI) were significantly associated with hypertension. Conclusions: Our findings reaffirmed the idea that NCDs are important public health concerns, and a simple BMI measurement would be a valuable tool with which to determine hypertension risks. Targeted surveillance and an appropriate health policy are necessary for such a vulnerable population in Thailand.

Fish Gelatin: Current Nutritional, Medicinal, Tissue Repair Applications and Carrier of Drug Delivery

Gelatin is obtained via partial denaturation of collagen and is extensively used in various industries. The majority of gelatin utilized globally is derived from a mammalian source. Several health and religious concerns associated with porcine/bovine gelatin were reported. Therefore, gelatin from a marine source is widely being investigated for its efficiency and utilization in a variety of applications as a potential substitute for porcine/bovine gelatin. Although fish gelatin is less durable and possesses lower melting and gelling temperatures compared to mammal-derived gelatin, various modifications are being reported to promote its rheological and functional properties to be efficiently employed. The present review describes in detail the current innovative applications of fish gelatin involving the food industry, drug delivery and possible therapeutic applications. Gelatin bioactive molecules may be utilized as carriers for drug delivery. Due to its versatility, gelatin can be used in different carrier systems, such as microparticles, nanoparticles, fibers and hydrogels. The present review also provides a perspective on the other potential pharmaceutical applications of fish gelatin, such as tissue regeneration, antioxidant supplementation, antihypertensive and anticancer treatments.

Knowledge, attitude and practices of lifestyle modification and associated factors among hypertensive patients on-treatment follow up at Yekatit 12 General Hospital in the largest city of East Africa: A prospective cross-sectional study

BACKGROUND

Hypertension is a devastating global public health challenge; studies indicated that Ethiopia has been affected by the burden of hypertension especially in urban areas. The overall prevalence of hypertension in Ethiopia was estimated to be 19.6% (23.5% in urban and 14.7% in rural population). Along with medical management of hypertension, appropriate lifestyle modification is a crucial and inexpensive means of hypertension control. The main purpose of the study was therefore to assess knowledge, attitude and practice of lifestyle modification among patients on follow up for hypertension treatment at Yekatit 12 General Hospital.

METHODS

A prospective cross-sectional study design was applied in Yekatit 12 General Hospital from October 28, 2018, to February 28, 2019, by allotting proportionate samples from the two chronic outpatients departments (OPD). Using single proportion sampling techniques, the study participants were selected and the total sample size calculated was 405. Primarily, clinical measurements were made according to the international standard set to verify true hypertensive patient's inclusions. Then, data about socio-demographic characteristics, lifestyle modification related to knowledge, attitude and practices were comprehensively collected using an interviewer-administered structured questionnaire. The collected data was entered into Epi-data exported to SPSS Window version of 22 for analysis. All variables with ρ-value less than 0.05 in the final model were considered as independently associated with knowledge, attitude and practices of patients' lifestyle modification. The strength of association was described by Odds Ratio (OR) at the corresponding CI of 95%.

RESULTS

The overall sampled hypertensive patients as compared to the planned sample size was 95.5% (n = 387), out of which 53.5% (n = 207) was male patients. The mean age was 50 years with a standard deviation of 14.4. The study revealed that 67.7% [95% CI (65.32%, 70.08%)] were knowledgeable; and 54.0% [95% CI (51.34%, 56.6%)] were reported to have favorable attitude towards lifestyle modification. Regarding their practices, 38% [95% CI (19.91%, 57.49%] of the respondents had good practices. Their monthly income [AOR = 2.39, 95% CI (1.12, 5.11)] and duration on-treatment follow up since diagnosed with hypertension [AOR = 4.39, 95% CI (1.20, 16.03)] were independently associated with knowledge. Concerning their damned practices, age [AOR = 7.71, 95% CI (2.4, 24.8)] and knowledge [AOR = 3.94, 95% CI (2.01, 7.72)] were independently associated with the practices.

CONCLUSION

Though the encouraging high knowledge status and favourable attitudes towards lifestyle modification among hypertensive patients, the practices are among the lowest findings report in all standards. Hence, older patients, jobless patients, and low-income patients and patients on long-term treatment follow up who were diagnosed with hypertension before 10 years needs special attention and interventions by the country NCDs policy formulators to rise their non-pharmacological practices to control high blood pressure and its consequences.
