INTRODUCTION
Cardiovascular disorders are one of the commonly recognized occupational diseases in the developed world. Individuals chronically exposed to noise at workplaces had a higher risk of developing elevated arterial blood pressure. There are limited studies in Ethiopia regarding this topic and thus this study determined the prevalence and determinant factors of occupational noise-induced pre-hypertension among metal manufacturing workers in Gondar city administration, Northwest Ethiopia.
METHODS
An institution-based cross-sectional study design was carried out. In this study, 300 study participants were recruited by census sampling method. A sound level meter was used to measure the working area noise level. A semi-structured pre-tested interviewer-administered questionnaire was used to collect sociodemographic and clinical data. Blood pressure was measured in a quiet room in the morning using a mercurial sphygmomanometer. Both bivariable and multi-variable binary logistic regressions were used to identify factors associated with noise-induced prehypertension. Adjusted odds ratio with 95% confidence interval was reported, and variables with p < 0.05 were considered as statistically associated factors with pre-hypertension.
RESULTS
The prevalence of noise-induced pre-hypertension was 27.7% (95% CI: 22.7-32.7). In multivariable logistic regression, working area noise level (AOR = 3.8, 95% CI: 6.8-8.9), 45-65 years' age (AOR = 9.8, 95% CI: 5.4-12.9), years of work experience ((6-10 years (AOR = 2.8, 95% CI: 1.98-5.90 and >10 years (AOR = 4.8, 95% CI: 7.8-9.75)), being a cigarette smoker (AOR = 3.6, 95% CI: 1.36-9.77), and alcohol consumption (AOR = 2.4, 95% CI: 1.06-1.04) were significantly associated with noise-induced prehypertension.
CONCLUSION
Workers in metal manufactures who were exposed to noise levels >85 dB developed elevated blood pressure. The odds of having prehypertension were increased by years of work experience, advanced age, smoking, and alcohol consumption. Our findings recommended that the real-world preventive strategies should be taken to lower the risk of noise-induced pre-hypertension hastened by occupational noise exposure.

To determine the prevalence of prehypertension (PH) and hypertension (AH) in quilombola children and adolescents, as well as to analyze sociodemographic, behavioral, and health characteristics.Prevalence study conducted in random samples of quilombola children and adolescents from 06 to 19 years of age, in remaining quilombo communities in Cachoeira-Bahia. Identification, sociodemographic, behavioral, anthropometric, and blood pressure (BP) data were used. Descriptive analyses of the variables of interest were performed based on absolute (N) and included frequencies (percentage, prevalence). Pearson's Chi-square (χ2) and Fisher Exact tests determined possible differences.Of the 668 participants, 54.3% were children, 51.2% were male, and 29.4% presented alterations in BP. PH and AH were found in 12.7% and 14.3% of the children, respectively; for adolescents, these values were 12.5% and 15.4%, respectively. No statistically significant difference was found between the prevalence of AH in the 2 population groups, nor between the PH measurements. Most families reported a low socioeconomic status. Among children, 6.6% were underweight, 14.6% were overweight, 10.7% were obese, 12.7% presented a Waist-to-Height Ratio (WHtR) > 0.5; 70.1% were inactive and 88.4% had a sedentary lifestyle; 5.6% of the adolescents were underweight, 12.8% were overweight, 9.2% were obese, 11.5% presented a WHtR > 0.5; 78% were inactive and 92.1% had a sedentary lifestyle. Normotensive children and adolescents, and those with alterations in BP differed only in terms of the Body Mass Index (P = .007) and WHtR (P < .001). The consumption of unhealthy foods was high.The high prevalence of PH and AH, as well as of exposure to potential risk factors for AH in quilombola children and adolescents, reveals a worrisome situation, and demands further studies to identify risk factors for this disease and the need for interventions beyond the health sector, especially as regards disease prevention and control in the early stages of life, aiming to reduce its prevalence as adults.

Hypertension is one of the most important and common cardiovascular risk factors. Defining the level at which blood pressure starts causing end-organ damage is challenging, and is not easily answered. The threshold of blood pressure defining hypertension has progressively been reduced over time, from systolic >160 mmHg to >150 mmHg, then to >140 mmHg; and now even blood pressures above 130 to 120 mmHg are labeled as 'pre-hypertension' by some expert committees. Are interest groups creating another 'pseudodisease' or is this trend scientifically justified? A recent meta-analysis published in BMC Medicine by Huang et al. clearly indicates that pre-hypertension (120 to 140/80 to 90 mmHg) is a significant marker of increased cardiovascular risk. This raises the question as to whether we now need to lower the threshold of 'hypertension' (as opposed to 'pre-hypertension') to >120/80 mmHg, redefining a significant proportion of currently healthy people as 'patients' with an established disease. These data need to be interpreted with some caution. It is controversial whether pre-hypertension is an independent risk factor or just a risk marker and even more controversial whether treatment of pre-hypertension will lower cardiovascular risk.

The purpose of this cross-sectional study was to identify risk factors in the normotensive and pre-hypertensive group based on the blood pressure results of healthy young adults from the Korean National Health and Nutrition Examination Survey 2018. The participants were 2225 healthy young adults between the ages of 19 and under 45, excluding those with a diagnosis of hypertension or taking antihypertensive medications. Of the 2225 participants, the normotensive group was 1498 (67.3%) and the pre-hypertensive group 727 (32.7%). Determinants of pre-hypertension were analyzed using multiple logistic regression based on a complex sample design. Factors related to pre-hypertension in young adults were age, smoking, waist circumference, diabetes, anemia, cholesterol levels including HDL cholesterol, and uric acid levels. Pre-hypertension is a pre-stage that can prevent the morbidity of hypertension through lifestyle control, so its management is very important. Furthermore, a young adult is a stage in the growth and development of human beings, in which lifestyles such as healthy behaviors, eating habits, and exercise are fixed. Therefore, it is very important to improve lifestyles such as diet, exercise, and smoking cessation and to control risk factors in young adults who are at the pre-hypertension stage for health promotion. Continuous health examinations should be conducted for young adults, and education that can be practiced based on clinical data through this should be implemented for community health.

Meta-Analysis
BACKGROUND
We aimed to address which interventions best control blood pressure (BP) and delay disease progression in prehypertension and to give recommendations for the best option following a quality rating.
METHODS
A Bayesian network meta-analysis was used to assess the effect of the intervention on BP reduction, delaying hypertension progression and final outcome, with subgroup analyses for time and ethnicity. Recommendations for interventions were finally based on cumulative ranking probabilities and CINeMA.
RESULTS
From 22,559 relevant articles, 101 eligible randomized controlled trial articles (20,176 prehypertensive subjects) were included and 30 pharmacological and non-pharmacological interventions were evaluated. Moderate-quality evidence demonstrated that angiotensin II receptor blockers, aerobic exercise (AE), and dietary approaches to stop hypertension (DASH) lowered systolic blood pressure (SBP). For lowering diastolic blood pressure (DBP), AE combined with resistance exercise (RE) or AE alone provided high quality evidence, with calcium channel blockers, lifestyle modification (LSM) combined with drug providing moderate quality evidence. LSM produced the best BP lowering effect at 12 months and beyond of intervention. In Asians, TCD bubble was moderate quality evidence for lowering SBP and RE may have had a BP lowering effect in Caucasians. No recommendation can be given for delaying the progression of hypertension and reducing mortality outcomes because of low to very low quality of evidence.
CONCLUSION
AE combined RE are preferentially recommended for BP control in prehypertension, followed by DASH. Long-term BP control is preferred to LSM. Asians and Caucasians add TCD bubble and RE to this list as potentially effective interventions.

BACKGROUND
Minimal data is available on the prevalence and correlates of hypertension and prehypertension in Dubai. The study aims to measure the prevalence of hypertension and pre-hypertension and the associated socio-demographic characteristics, behavioral risk factors and comorbidities among the adult population of Dubai.
METHODS
This study used data from the Dubai Household Health Survey, 2019. A cross-sectional population survey based on a complex stratified cluster random design. The total eligible sample included 2530 adults (18+). Sociodemographic and behavioral factors were considered as independent covariates. The main study outcome variables, pre-hypertension and hypertension, were ordinal, with normotension as the reference group.
RESULTS
The overall prevalence of hypertension in adults was 32.5% (38.37% in males and 16.66% in females). Prehypertension was prevalent in 29.8% of adults in Dubai (28.85% in males and 32.31% in females). The multivariate logistic regression analysis revealed that age groups, gender, occupation, and high Body Mass Index were significantly associated with a higher risk of hypertension at the level of P < 0.05. No clear trend toward a higher correlation of hypertension was noted with the increase in age, except after the age of 50 years. Males were five- times more likely to be hypertensive than females. Participants enrolled in skilled and service works had a five times higher risk of hypertension, compared with the reference group (professionals). Obese subjects had a 5.47-times greater correlation of hypertension compared with normal-weight subjects. Physically active individuals were less likely to develop hypertension. For the correlates with prehypertension in the present analysis, skilled and service workers and those working in elementary jobs had a higher risk of prehypertension, compared with the reference group (professionals) Individuals with a status of overweight were associated with a higher prevalence of prehypertension compared with people of normal weight.
CONCLUSIONS
This study showed a high prevalence of prehypertension and hypertension among adults in Dubai. Some socio-demographic and behavioral risk factors were correlated with prehypertension and hypertension among the studied population. Interventions aiming at increasing public awareness about such risk factors are essential.

Comparative Study
BACKGROUND
The current nationwide study, for the first time, aimed to assess and compare the trend of pre-hypertension and hypertension among urban and rural adolescents in Iran.
METHODS
This study has been conducted in the framework of the National Surveys of Risk Factors for Non-Communicable Diseases. To estimate pre-hypertension and hypertension prevalence among 9715 adolescents, aged 15-19 years, data collected in four repeated cross-sectional surveys (2007-2011) has been used. The prevalence trends of pre-hypertension and hypertension were examined across urban and rural areas of Iran. To calculate the adjusted prevalence ratios (PRs) of pre-hypertension and hypertension over cycles across area of residence and genders, a complex sample survey and multinomial logistic analysis were performed.
RESULTS
Using the definition of pre-hypertension and hypertension presented by the seventh Joint National Committee (JNC-VII) for adolescents, after adjusting for confounders, the prevalence of pre-hypertension changed in both urban (boys:28.96% to 29.24% and girls:18.33% to 20.06%) and rural (boys 31.58% to 32.05% and girls 22.25% to 24.13%) areas over the study duration. Non-significant rising prevalence of hypertension was also observed in boys and girls of both regions (urban 12.76% to 15.04% and 8.02% to 9.06%; rural 9.95% to 11.79% and 10.35% to 11.60%, for boys and girls respectively). The adjusted prevalence ratios (PRs) of pre-hypertension (2.16; 95% CI 1.68-2.79 and 1.92, 95% CI 1.57-2.34, in urban and rural, respectively) and hypertension (2.40; 95% CI 1.65-3.51 and 1.82, 95% CI 1.36-2.45, in urban and rural, respectively) were higher in boys than girls. Comparing the adjusted PRs of pre-hypertension and hypertension in urban versus rural areas, in both genders, showed higher PRs of pre-hypertension in rural girls (1.33, 95% CI 1.01-1.75).
CONCLUSION
The current results showed high constant trends of pre-hypertension and hypertension in Iranian boys and girls, residing in both urban and rural areas.

Meta-Analysis Review
BACKGROUND
High blood pressure represents a major public health problem. Worldwide, approximately one-fourth of the adult population has hypertension. Epidemiological and experimental studies suggest a link between hyperuricemia and hypertension. Hyperuricemia affects 25% to 40 % of individuals with untreated hypertension; a much lower prevalence has been reported in normotensives or in the general population. However, whether lowering serum uric acid (UA) might lower blood pressure (BP) is an unanswered question.
OBJECTIVES
To determine whether UA-lowering agents reduce BP in patients with primary hypertension or prehypertension compared with placebo.
SEARCH METHODS
The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials up to February 2016: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 2), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also searched LILACS up to March 2016 and contacted authors of relevant papers regarding further published and unpublished work.
SELECTION CRITERIA
To be included in this review, the studies had to meet the following criteria: 1) randomized or quasi-randomized, with a group assigned to receive a UA-lowering agent and another group assigned to receive placebo; 2) double-blind, single-blind or open-label; 3) parallel or cross-over trial; 4) cross-over trials had to have a washout period of at least two weeks; 5) minimum treatment duration of four weeks; 6) participants had to have a diagnosis of essential hypertension or prehypertension, and hyperuricemia (serum UA greater than 6 mg/dL in women, 7 mg/dL in men and 5.5 mg/dL in children/adolescents); 7) outcome measures assessed included change in clinic systolic, diastolic or 24-hour ambulatory BP.
DATA COLLECTION AND ANALYSIS
The two review authors independently collected the data using a data extraction form, and resolved any disagreements via discussion. We assessed risk of bias using the Cochrane Collaboration' Risk of bias' tool.
MAIN RESULTS
In this review update, we examined the abstracts of 349 identified papers and selected 21 for evaluation. We also identified three ongoing studies, the results of which are not yet available. Three other randomized controlled trials (RCTs) (two new), enrolling individuals with hypertension or prehypertension, and hyperuricemia, met the inclusion criteria for the review and were included in the meta-analysis. Low quality of evidence from three RCTs indicate no reduction in systolic (MD -6.2 mmHg, 95% CI -12.8 to 0.5) or diastolic (-3.9 mmHg, 95% CI -9.2 to 1.4) 24-hour ambulatory BP with UA-lowering drugs compared with placebo. Low quality of evidence from two RCTs reveal a reduction of systolic clinic BP (-8.43 mmHg, 95% CI -15.24 to -1.62) but not diastolic clinic BP (-6.45 mmHg, 95% CI -13.60 to 0.70). High quality of evidence from three RCTs indicates that serum UA levels were reduced by 3.1 mg/dL (95% CI 2.4 to 3.8) in the participants that received UA-lowering drugs. Very low quality of evidence from three RCTs suggests that withdrawals due to adverse effects were not increased with UA-lowering therapy (RR 1.86, 95% CI 0.43 to 8.10).
AUTHORS' CONCLUSIONS
In this updated systematic review, the RCT data available at present are insufficient to know whether UA-lowering therapy also lowers BP. More studies are needed.

OBJECTIVES
The study was primarily aimed at estimating the prevalence of hypertension and pre-hypertension and the risk factors of hypertension in the North Indian state of Punjab. It also aimed at assessing the magnitude of undiagnosed cases of hypertension in the community and ascertaining the blood pressure control status of those on treatment.
METHODS
A non-communicable disease risk factor survey (based on WHO-STEPS approach) was done in the state of Punjab, India in a multistage stratified sample of 5127 individuals. The study subjects were administered the WHO STEPS-questionnaire and also underwent anthropometric and blood pressure measurements.
RESULTS
Overall prevalence of HTN among the study participants was found out to be 40.1% (95% CI: 38.8-41.5%) whereas prevalence of pre-hypertension, isolated diastolic and isolated systolic hypertension were 40.8% (39.5-42.2%), 9.2% (8.4-10.0%) and 6.5% (5.9-7.2%) respectively. Age group (45-69 years), male gender, social group, marital status, alcohol use, obesity and salt intake (> = 5 gms/day) were the risk factors significantly associated with HTN. Among all persons with HTN, only 30.1% were known case of HTN or on treatment, among whom nearly 61% had controlled blood pressure. Patients with uncontrolled BP were more frequently male, obese patients, with sedentary lifestyle and patients with diabetes.
CONCLUSIONS
The study reported alarmingly high prevalence of hypertension, especially of undiagnosed or untreated cases amongst the adult population, a significant proportion of whom have uncontrolled blood pressure levels. This indicates the need for systematic screening and awareness program to identify the undiagnosed cases in the community and offer early treatment and regular follow up.

African Health Sciences Dec 2016We aimed to assess the prevalence of prehypertension and its associated factors in a population of Congolese pre and postmenopausal women.
OBJECTIVES
We aimed to assess the prevalence of prehypertension and its associated factors in a population of Congolese pre and postmenopausal women.
METHODS
We had consecutively recruited 200 women (100 premenopausal and 100 postmenopausal) aged 40 - 60 years at the department of Gynecology and Obstetrics, University of Kinshasa Hospital, and AKRAM Medical Center in Kinshasa, DRC. An interview was carried out using a questionnaire that comprised questions related to lifestyle, menses characteristics, medical history of diabetes, CVD, hypertension, current antihypertensive medication and use of traditional medicine. In addition, physical examination and biological measurements were performed. Multivariate logistic regression analysis was used to assess associated factors with prehypertension.
RESULTS
Of the participants, 34% were normotensive, 38.5 % prehypertensive and 27.5% hypertensive. Compared to normal blood pressure, prehypertension was common in the older (age>50 years of age) women. Menopause, the use of traditional medicine and older age were associated with prehypertension. However, only menopause (aOR: 2.71; 95%CI: 1.10-3.52) and the use of traditional medicine (aOR: 2.24; 95% CI: 1.07-4.7) remained associated with prehypertension in a multivariate logistic regression analysis.
CONCLUSION
This study showed that prehypertension is common among Congolese menopausal women, and that menopause and the use of traditional medicine were the main factors associated with prehypertension.
