Long-Term Herbicide Mixture Exposure Increases Hypertension Risk and Aging Biomarkers Play Mediation Effects: A Nested Case-Control Study

Sleep pattern, behavior, duration and incident hypertension: results from two large prospective cohorts

Abstract Background Poor sleep quality pose significant public health challenges globally. The objective of this study is to investigate the association between sleep quality, duration and the risk of hypertension. Methods 284,250 adults from the UK Biobank (UKB) and 6,104 participants from the English Longitudinal Study of Ageing (ELSA) were analyzed. The exposures of interest were sleep quality and duration. Sleep quality was evaluated based on the number of healthy sleep behaviors (UKB cohort) or questionnaire adapted from the Jenkins Sleep Problems Scale (ELSA cohort). Participants were divided into three groups based on the assessment of sleep quality. Long sleep is characterized by a duration exceeding 8 hours, medium sleep ranges from 7 to 8 hours and short sleep denotes less than 7 hours of sleep. The primary endpoint was incident hypertension. Results In UKB cohort, participants with poor sleep quality showed significantly higher risk of hypertension compared those with healthy sleep quality (hazard ratio [HR] 1.276, confidence interval [CI] 1.21, 1.346). Short sleep duration (≤7h) was associated with an elevated hypertension risk in participants regardless of different sleep quality, and both short(≤7h) and prolonged sleep time (≥9h) were associated with an increased hypertension risk in the poor sleep quality group. Several factors were independently associated with a lower risk of hypertension, including appropriate sleep duration (7-8 hours per day), absence of frequent insomnia, no self-reported snoring(P<0.001). Associations between sleep quality and an increased risk of hypertension remained significant regardless of genetic susceptibility to hypertension (P for interaction= 0.067). Conclusions Poor sleep quality is associated with an elevated risk of hypertension. Adjusting sleep behavior to enhance sleep quality within a recommended range could be a promising strategy for mitigating the risk of hypertension.

Ultraprocessed Food Consumption and Hypertension Risk in the REGARDS Cohort Study.

This study examined the longitudinal association between ultraprocessed food (UPF) consumption and overall hypertension risk and explored the contribution of UPF to racial disparities in risk for hypertension. We analyzed data from 5957 participants from the REGARDS cohort study (Reasons for Geographic and Racial Disparities in Stroke) free from hypertension during visit 1 (2003-2007), had complete dietary information at visit 1, and completed visit 2 (2013-2016). UPF consumption was measured using the Nova classification system and operationalized percent calories and grams. The main outcome was incident hypertension. Logistic regression was used for analysis. Thirty-six percent of participants developed hypertension at visit 2. Results showed a positive linear relationship between UPF and hypertension incidence. Aggregate model results showed that those in the highest UPF consumption quartile had 23% greater odds of incident hypertension compared with the lowest quartile. Multivariable results showed that Black and White participants in the highest consumption quartile had 1.26 (95% CI, 0.92-1.74) and 1.22 (95% CI, 1.01-1.47) greater odds of hypertension compared with those in the lowest quartile, respectively. Analyses using UPF consumption as percent grams showed similar aggregate results; however, race-stratified results differed. Findings were no longer statistically significant among White participants (odds ratio, 1.09 [95% CI, 0.89-1.33]) but showed significant differences in incident hypertension between Black participants in the highest versus lowest UPF quartiles (odds ratio, 1.43 [95% CI, 1.01-2.02]). This study demonstrated that high consumption of UPF is associated with increased hypertension risk. Further research is warranted to better understand differences in the intakes of UPF subgroups that may underpin the racial differences in hypertension incidence observed with different UPF metrics.

Body roundness index and the risk of hypertension: a prospective cohort study in Southwest China

BackgroundBody roundness index (BRI) is an anthropometric measure related to obesity, combining waist circumference (WC) and height to more accurately reflect body fat. This study aims to investigate the relationship between BRI and the risk of hypertension using data from a prospective cohort study in Southwest China.MethodsData for the study were derived from Guizhou Population Health Cohort Study (GPHCS), established in 2010. A total of 9,280 participants (aged 18 to 95 years, mean 41.53 ± 14.15 years) from 48 townships across 12 districts/counties were surveyed at baseline through multistage stratified random cluster sampling. Cox proportional risk models were employed to analyze the association between BRI and the risk of hypertension, estimating hazard ratios (HRs) and 95% confidence intervals (CIs) after adjusting for confounding factors. The relationship between BRI and the onset time of hypertension was analyzed using the time failure acceleration model.ResultsOver a median follow-up period of 6.64 years, 1,157 participants were diagnosed with hypertension. After adjusting for confounding variables, each unit increase in BRI was associated with a 17% increase in hypertension risk (HR = 1.17, 95% CI: 1.11, 1.24, P for trend < 0.001). Compared to participants in the first quartile (Q1) of BRI, the risk of hypertension for those in the third quartile (Q3) and fourth quartile (Q4) was 1.31 (95% CI: 1.10, 1.56) and 1.53 (95% CI: 1.28, 1.84), respectively. Each unit increase in BRI advanced the onset of hypertension by 0.26 years (95% CI: 0.16, 0.35).ConclusionThis study indicates that BRI has a positive association with hypertension and can accelerate the onset of hypertension in the Chinese population. It is suggested that reducing BRI by controlling abdominal fat may be one of the effective measure to prevent hypertension.

The Association Between Smoking Behavior and the Risk of Hypertension: Review of the Observational and Genetic Evidence.

Cigarette smoking is one of the world's largest avoidable risk factors for morbidity and mortality. Numerous studies have investigated the association between smoking and hypertension (HTN). Although observational data and cross-sectional research often exhibit a link between smoking and HTN, establishing causation remains challenging owing to potential confounding variables. Mendelian randomization (MR), a genetic epidemiological technique that employs genetic variants as instrumental variables, offers a more robust approach for evaluating causal links. This review aimed to explore both the observational and causal relationships between smoking and the risk of HTN. A comprehensive literature search across major electronic databases was conducted to identify relevant observational and Mendelian randomization (MR) studies on smoking and HTN risk. Various characteristics were included during study selection, such as study design, exposure assessment, and age range. Standardized processes were used for data retrieval and quality evaluation. Analysis of observational data revealed a paradoxical association between smoking and the risk of HTN, where a lower risk was observed among current smokers when compared to non-smokers. However, observational analysis also presented a dose-response effect with greater smoking intensity showed a modest linear increase in HTN risk, and older smoking initiation was associated with a slight increase in HTN risk (compared with younger). In contrast, MR-based causal estimates provide inconsistent evidence regarding the causal relationship between smoking behavior and HTN. Some MR analyses indicated a potential causal link between smoking and HTN; but this was not consistent. Observational studies suggest a paradoxical association between smoking and HTN. However, MR studies do not provide sufficient evidence to establish a causal relationship. Regardless, lifestyle variables remain crucial for overall health. Healthcare professionals should regularly assess smoking status and provide counseling for quitting. Further research is needed to clarify the underlying processes, identify mediators, and evaluate the interventions.

Association between inflammatory biomarkers and hypertension among sedentary adults in US: NHANES 2009-2018.

Our study focuses on the relationship between inflammatory biomarkers and hypertension among sedentary adults in the United States, using data from the National Health and Nutrition Examination Survey (NHANES) from 2009 to 2018. We categorized 24,614 participants into two groups based on their daily sedentary time: 9607 individuals in the sedentary group (≥7h) and 15,007 in the non-sedentary group(<7h). We found that the sedentary group had a significantly higher prevalence of hypertension than the non-sedentary group. Using weighted multiple logistic regression and smoothing curves, we assessed the correlation between inflammatory biomarkers and hypertension among the sedentary adults. The odds ratios for hypertension were 1.92 for the monocyte to high-density lipoprotein ratio (MHR), 1.15 for the systemic inflammation response index (SIRI), and 1.19 for the natural logarithm of the systemic immune-inflammation index (lnSII), all showing nonlinear associations. Furthermore, a significant positive correlation was found between sedentary time and inflammatory biomarkers (MHR, SIRI, and lnSII). Our findings suggest that prolonged sedentary behavior in the US significantly increases hypertension risk, likely due to marked increases in inflammation markers.

Association between liver fat level and risk of hypertension: evidence from a Chinese health examination dataset.

Hypertension development is predominantly influenced by inflammation, excessive fat deposition, and metabolic irregularities. Among these factors, liver fat accumulation is a critical metabolic disorder. However, the quantification of liver fat levels and its associated risk for hypertension incidence remain ambiguous. This project is designed to explore the association between liver fat levels and the risk of hypertension in a healthy population. This cross-sectional study involved 4955 participants from the Health Management Center at Henan Provincial People's Hospital who were surveyed between February 2020 and February 2023. Participants were categorized into four groups based on liver fat quartiles. Subgroup analyses, restricted cubic spline regression models, and logistic regression were utilized to assess the association between liver fat levels and hypertension risk. The relationships between liver fat levels and inflammatory markers were examined using multiple linear regression models. Additionally, a mediation analysis was conducted to explore the role of inflammatory factors in the relationship between liver fat and hypertension risk. Participants with hypertension exhibited greater liver fat levels than did those without hypertension. An increased risk of hypertension was associated with elevated liver fat levels, even after adjusting for other covariates [Q4 vs. Q1 in model II: odds ratio (OR = 1.28), 95% confidence interval (CI) = 1.04-1.59, P = 0.022; P for trend = 0.039]. A nonlinear relationship was observed between liver fat level and hypertension risk, with a notable increase in hypertension risk occurring at liver fat levels greater than 8.65%. Additionally, a positive correlation was found between inflammatory markers and liver fat levels. A mediation effect of 4.76% was noted, linking hypertension risk and liver fat levels through neutrophils. Liver fat levels exceeding 8.65% significantly elevated the risk of hypertension. Inflammatory factors serve as crucial mediators of the relationship between liver fat and hypertension.

Prevalence and Incidence of Hypertension and Diabetes Mellitus Among HIV-Infected Individuals Receiving HAART in Chongwe District, Lusaka Province, Zambia

Background: The Zambia National Health Strategic Plan (ZNHSP) 2011–2017 underscores the need for community-level risk factor stratification to bolster insufficient incidence and prevalence data. This study evaluates the prevalence and incidence of hypertension and diabetes mellitus in HIV-infected patients on Highly Active Anti-Retroviral Therapy (HAART) and assesses associations with ARV use. Methodology: A retrospective cohort analysis was conducted using the SMART CARE database in Chongwe district, involving 2070 HIV-infected persons on HAART. Statistical analysis included Chi-square, Kruskal-Wallis tests, and logistic regression. Results: Among participants, 33.8% exhibited hypertension, with an incidence case fatality rate of 85.7 per 1000 person-years (PYFU). Hypertension was notably higher in men (64%) than women (49%) and prevalent in the 18–45 age group (57.2%). The incidence of type II diabetes was 37.4 per 1000 PYFU. Logistic regression highlighted significant predictors for both conditions, including ART combination, age, and smoking status. Conclusion: High prevalence and incidence rates of hypertension and type II diabetes were observed among HIV-positive individuals on HAART. Certain HAART combinations, particularly twoNRTIs plus a PI or INSTI, correlated with increased hypertension risk, while combinations including NNRTI or INSTI were linked to higher diabetes incidence.

Association of triglyceride glucose index and risk of incident hypertension: a prospective cohort study

Objective: To explore the relationship between the triglyceride glucose (TyG) index and the risk of developing hypertension among rural Chinese adults. Methods: A prospective cohort study was conducted from 2007 to 2008, involving 20 194 adults selected through random cluster sampling from a rural community in Luoyang City, Henan Province. Follow-ups were carried out in 2013-2014 and 2018-2020. After excluding participants with hypertension at baseline, those with missing TyG index data, individuals who passed away during follow-up, and those with incomplete hypertension status at the second visit, 9 802 participants were included in the analysis. Baseline and follow-up assessments included questionnaire interviews, physical measurements (including blood pressure), and blood sample collection for fasting lipid and glucose levels. Participants were divided into four groups according to TyG index quartiles, and a modified Poisson regression model was utilized to assess the association between TyG index quartiles and hypertension risk. Results: The study cohort comprised 9 802 participants with a median age of 48 (39, 57) years, including 3 803 males (38.80%). Participants were distributed across TyG index quartiles as follows: TyG<8.2 group (2 224 individuals), TyG 8.2-8.5 group (2 653 individuals), TyG 8.6-8.9 (2 441 individuals), and TyG≥9.0 (2 484 individuals). Over a follow-up period of (11.1±1.3) years, 3 378 subjects developed hypertension, resulting in a cumulative incidence of 34.46% (3 378/9 802). The risk of hypertension increased with higher TyG index quartiles (Ptrend<0.05). Compared to the TyG<8.2, the TyG 8.2-8.5 (RR=1.11, 95%CI 1.01-1.22, P=0.023), TyG 8.6-8.9 (RR=1.16, 95%CI 1.06-1.27, P=0.023), and TyG≥9.0 (RR=1.20, 95%CI 1.10-1.31, P=0.023) exhibited increased hypertension risk after adjusting for age, gender, educational level, and other potential confounders. Subgroup analyses based on gender and age at baseline yielded results consistent with the main analysis. Conclusions: The TyG index is positively correlated with the risk of developing hypertension in the rural adult population.

Major depressive disorder increased the risk of hypertension: A Mendelian randomization study

BackgroundDespite the high prevalence of comorbid hypertension in patients with major depressive disorder (MDD), the relationship between the two diseases has received little attention. Previous observational studies have descripted the association between MDD and hypertension, the causality from MDD on hypertension remained unknown. The present Mendelian randomization (MR) study aimed to assess the causal effect of MDD on hypertension. MethodsA set of genetics instrument was used for analysis, derived from publicly available genetic meta-analysis data. A total of 44 single-nucleotide polymorphisms (SNPs) associated with MDD. The largest genome-wide association study (GWAS) for hypertension (54,358 cases and 408,652 controls) was used to assess the effect of MDD on hypertension. Inverse variance weighted method (IVW), weighted median method (WM), and MR-Egger regression were used for MR analyses. The MR-Egger_intercept test and Cochran's Q statistic were used to determine the pleiotropy and the heterogeneity, respectively. ResultsA total of 28 independent and effective MDD genetic instrumental variables were extracted from the hypertension GWAS summary statistics. Pleiotropy analysis suggested no significant pleiotropic variant among the 28 selected MDD genetic instrument variants in hypertension GWAS datasets. As MDD based on genetic changes increased, the risk of hypertension increased using MR-Egger (OR = 1.004436, 95%CI 0.9884666–1.020663, P = 0.5932928), WM (OR = 1.000499, 95%CI 1.0000188–1.000980, P = 0.0416871), and IVW (OR = 1.000573, 95%CI 1.0000732–1.001074, P = 0.0246392). Our results were robust, with no obvious bias based on investigating the single MDD SNP on hypertension. ConclusionsOur result suggested a causal associated between genetically increased MDD and increased hypertension risk in European population.

Associations between hypertension with reproductive and menopausal factors: An integrated women's health programme (IWHP) study.

Women are less likely to have classic cardiovascular risk factors than men, and events during their reproductive and menopausal years may increase hypertension risk. The aim of this study is to examine woman-specific factors, including menstrual, reproductive and pregnancy complications, in relation to the prevalence of hypertension in mid-life Asian women. This is a cross-sectional study of 1146 healthy women aged 45-69 years, from a multi-ethnic Asian cohort. The women completed an extensive questionnaire that included their sociodemographic details, medical history, lifestyle and physical activity, and reproductive and menopausal history. They also underwent objectively measured physical performance tests and a dual X-ray absorptiometry scan. Hypertension was defined as a systolic BP ≥140 and/or diastolic BP ≥90mm Hg, past diagnosis by a physician, or use of antihypertensive medications. Multivariable logistic regression was used to assess the independent risk factors for hypertension. The average age of the 1146 women analysed was 56.3 (SD 6.2) years, and 55.2 percent of them were hypertensive. The prevalence of gestational diabetes and gestational hypertension was 12.6% and 9.4%, respectively. Besides age, abnormal menstrual cycle length at 25 years of age (OR:2.35, CI:1.34-4.13), preeclampsia (OR:2.46, CI:1.06-5.74), increased visceral adiposity (OR:4.21, CI:2.28-7.79) and reduced physical performance (OR:2.83, CI:1.46-5.47) were independently associated with hypertension in Asian women. Our findings highlight the necessity of including features of menstrual and reproductive history as possible indicators of hypertension risk in cardiovascular disease risk assessment and prevention among Asian women. Reducing visceral adiposity and exercise to improve physical performance may help women avoid developing hypertension.

Association of systemic immunity-inflammation index with metabolic syndrome in U.S. adult: a cross-sectional study

BackgroundMetabolic syndrome (MetS) is a pathological condition characterized by the abnormal clustering of several metabolic components and has become a major public health concern. We aim to investigate the potential link of Systemic immunity-inflammation index (SII) on MetS and its components.Methods and resultWeighted multivariable logistic regression was conducted to assess the relationship between SII and MetS and its components. Restricted cubic spline (RCS) model and threshold effect analysis were also performed. A total of 6,999 U.S. adults were enrolled. Multivariate model found that SII were positively associated with MetS (OR = 1.18;95CI%:1.07–1.30) and hypertension (OR = 1.22; 95CI%:1.12–1.34) in a dose-dependent manner. When SII was converted into a categorical variable, the risk of MetS increased by 36% and the risk of hypertension increased by 53% in the highest quantile of SIIs. The RCS model confirmed linear associations between SII and MetS, as well as a non-linear association between SII and certain components of MetS, including hypertension, hyperglycemia, low HDL, and hyperlipidemia. Meanwhile, the relationship between SII and hypertension presents a J-shaped curve with a threshold of 8.27, above which the risk of hypertension increases. Furthermore, in MetS and hypertension, age, sex, body mass index (BMI), and race were not significantly associated with this positive association based on subgroup analyses and interaction tests(p for interaction > 0.05).ConclusionsThe present study indicated that there was a higher SII association with an increased risk of MetS and hypertension in adults. However, further prospective cohort studies are required to establish a causal relationship between SII and MetS, as well as its components.

Periodontitis and hypertension are linked through systemic inflammation: A 5-year longitudinal study.

To investigate the associations between periodontitis and hypertension and potential mediation via systemic inflammation through a 5-year longitudinal study. The severity and extent of periodontitis were determined using probing depth (PD). Oral hygiene was assessed using plaque scores. The associations between periodontal variables and 5-year blood pressure changes or incident hypertension were analysed using linear or Poisson regression, adjusting for potential confounders. Mediation analysis of two systemic inflammatory biomarkers, namely white blood cell count (WBC) and C-reactive protein (CRP) levels, was performed. The study population included 901 hypertension-free participants, aged 50-73 years. Greater mean PD, higher percentage of sites with PD ≥ 6 mm and poor oral hygiene were associated with elevated systolic blood pressure and increased hypertension risk (relative risks = 1.17 [95% confidence interval [CI]: 1.02-1.34], 1.13 [95% CI: 1.02-1.26] and 1.08 [95% CI: 1.03-1.13], respectively). Periodontitis and poor oral hygiene were associated with higher WBC and CRP levels (p < .05), which, in turn, were associated with increased hypertension risk (p < .05). WBC and CRP jointly mediated 14.1%-26.9% of the associations between periodontal variables and incident hypertension. Periodontitis and poor oral hygiene were associated with increased hypertension risk, and systemic inflammation was, in part, a mediator of these associations.

Role of oral health in heart and vascular health: A population-based study.

Conditions such as hypertension, cardiovascular diseases, and hypercholesterolemia, are a major public health challenge. This study investigates the influence of oral health indicators, including gum bleeding, active dental caries, tooth mobility, and tooth loss, on their prevalence in Hungary, considering socioeconomic, demographic, and lifestyle factors. Data from the 2019 Hungarian European Health Interview Survey with 5,603 participants informed this analysis. Data were accessed from the records maintained by the Department of Health Informatics at the University of Debrecen between September and November 2023. Variable selection employed elastic net regularization and k-fold cross-validation, leading to high-performing predictors for weighted multiple logistic regression models. Sensitivity analysis confirmed the findings' validity. Significant links were found between poor oral health and chronic cardiac conditions. Multiple teeth extractions increased hypertension risk (OR = 1.67, 95% CI: [1.01-2.77]); dental prosthetics had an OR of 1.45 [1.20-1.75]. Gum bleeding was associated with higher cardiovascular disease (OR = 1.69 [1.30-2.21]) and hypercholesterolemia risks (OR = 1.40 [1.09-1.81]). Oral health improvement may reduce the risk of cardiac conditions. This underscores oral health's role in multidisciplinary disease management.

Prevalence and associated factors of hypertension in young adults: A cross-sectional study.

Objective: To explore the relationships between hypertension and modifiable risk factors such as daily smoking, sedentary lifestyle and obesity in young adults. Study Design: Cross-sectional study. Setting: Akhtar Saeed Teaching Hospital, Lahore. Period: July 2022 to Dec 2022. Material &amp; Methods: Cross-sectional analysis was conducted on a sample population of 500 individuals, aged 18-39. A standardized, self-administered questionnaire was used to gather information on tobacco usage, physical activity level, parental history of hypertension, and other relevant demographic information. Additional assessments such as dietary habits were conducted through face-to-face interviews. Multivariate logistic regression models were employed to assess the associations between hypertension and various risk factors, controlling for age, gender and BMI categories. Results: The study corroborated the significant association between daily smoking and hypertension (aOR = 1.7, 95% CI 1.3–2.4, p = 0.001) and revealed an 80% increase in hypertension risk associated with a sedentary lifestyle (OR = 1.8, 95% CI 1.2–2.7, χ² = 8.21, p = 0.004). Obesity was also strongly associated with hypertension (aOR = 3.2, 95% CI 2.1–4.8, p &lt; 0.001). There was no significant difference between males and females in terms of hypertension risk. Conclusion: Hypertension is significantly associated with smoking, sedentary lifestyle and obesity.

The Association of Hypertension with Perfluoroalkyl and Polyfluoroalkyl Substances.

Perfluoroalkyl and polyfluoroalkyl substance (PFAS) is a large group of fluorinated synthetic chemicals, e.g., perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorohexanesulfonic acid (PFHxS), perfluorodecanoic acid (PFDA), and perfluorononanoic acid (PFNA). Many epidemiological studies have found that PFAS exposure is associated with hypertension risk, but others possess a different opinion. Overall, the relationship between PFASs and hypertension risk remains controversial. We sought to conduct a systematic review and meta-analysis to clarify the association between PFAS exposure and human risk of hypertension.We conducted a meta-analysis based on population-involving studies published from 1975 to 2023, which we collected from Web of Science, PubMed, and Embase databases. The odds ratio (OR) and standardized mean difference (SMD), with their 95% confidence interval (CI), were used to assess the risk of hypertension with PFAS exposure. The statistical heterogeneity among studies was assessed with the Q-test and I2 statistics. Research publications related to our meta-analysis topic were systematically reviewed.Fourteen studies involving 71,663 participants, in which 26,281 suffered hypertension, met the inclusion criteria. Our analyses suggest that exposure to general PFAS (OR = 1.09, 95% CI = 1.04-1.14) or PFOS (OR = 1.17, 95% CI = 1.05-1.30) is associated with hypertension risk. Specifically, elevated levels of general PFAS (SMD = 0.25, 95% CI = 0.08-0.42), PFHxS (SMD = 0.17, 95% CI = 0.07-0.27), and PFDA (SMD = 0.08, 95% CI = 0.02-0.13) are associated with a high risk of hypertension.Our meta-analysis indicates that PFAS exposure is a risk factor for hypertension, and increased hypertension risk is associated with higher PFAS levels. Further study may eventually provide a better and more comprehensive elucidation of the potential mechanism of this association.

Sex specific associations between serum uric acid levels and risk of hypertension for different reference values of high blood pressure

Abstract Background Uric acid (UA) has been linked to the development of hypertension. However the sex specific associations between UA levels and different diagnostic blood pressure (BP) references is unknown. Purpose We aimed to ascertain the association between serum UA quartiles, hyperuricemia, and 5-year hypertension incidence and weather lower BP diagnostic references may alter these associations in men and women without cardiometabolic diseases. Methods This 5-year study used the check-up data from a hospital. We excluded participants with hypertension (defined as BP ≥140/90 mmHg in cohort 1 and BP ≥130/80 mmHg in cohort 2), diabetes, dyslipidemia, obesity, estimated glomerular filtration rate (eGFR) &amp;lt;60 ml/min/1.73m², metabolic syndrome, history of gout, and UA lowering medication. We categorized UA into quartiles as follows: men: 1st quartile UA≤4.8 mg/dL, 2nd quartile 4.9-5.6 mg/dL, 3rd quartile 5.7-6.4 mg/dL, and 4th quartile UA≥6.5 mg/dL; women: 1st quartile UA≤3.4 mg/dL, 2nd quartile 3.5-4.0 mg/dL, 3rd quartile 4.1-4.7 mg/dL, and 4th quartile UA≥4.8 mg/dL. Hyperuricemia was defined as UA&amp;gt;7 mg/dL in men and UA&amp;gt;6 mg/dL in women. To analyze the effects of UA on development of hypertension, we adjusted for age, body mass index, systolic BP, diastolic BP, tobacco smoking, alcohol consumption, exercise habit, serum triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting plasma glucose, and eGFR by sex in both cohorts. The outcome was 5-year hypertension incidence defined as BP ≥140/90 mmHg in cohort 1 and BP ≥130/80 mmHg in cohort 2. Results In total, 21,514 participants (age, 52.9±10.9 years; men, 39.8%), were enrolled in cohort 1, and 15,316 participants (age, 51.3±10.9 years; men, 36.5%), in cohort 2. The incidence of hypertension in cohort 1 and cohort 2 over a 5-year period was 16.3% and 29.7% in men and 10.9% and 21.4% in women, respectively. Using multivariable logistic regression, we found that when comparing the fourth to first UA quartile, there was an increased risk of hypertension in men in cohort 1, OR 1.36 (95% CI, 1.13-1.63, P&amp;lt;0.01) and cohort 2, OR 1.31 (95% CI, 1.09-1.57, P&amp;lt;0.01) but not in women, cohort 1, OR 1.14 (95% CI, 0.95-1.36, P=0.16) and cohort 2, OR 1.14 (95% CI, 0.98-1.34, P=0.10) respectively. In contrast, for hyperuricemia, we observed increased hypertension risk only in men in cohort 1, OR 1.23 (95% CI, 1.07-1.42, P=0.02) and women were associated with increased risk of hypertension in cohort 2, OR 1.57 (95% CI, 1.14-2.16, P&amp;lt;0.01) but not in men OR 1.15 (95% CI 0.95-1.40, P=0.15). Conclusion Uric acid effect on development of hypertension is affected by sex and incidence differs with the BP reference used. We emphasize on early UA screening to enhance hypertension prevention among cardiometabolic free population.Hypertension 5-Year Incidence Proportion

Salty Subjects: Unpacking Racial Differences in Salt-Sensitive Hypertension.

To review underlying mechanisms and environmental factors that may influence racial disparities in the development of salt-sensitive blood pressure. Our group and others have observed racial differences in diet and hydration, which may influence salt sensitivity. Dietary salt elicits negative alterations to the gut microbiota and immune system, which may increase hypertension risk, but little is known regarding potential racial differences in these physiological responses. Antioxidant supplementation and exercise offset vascular dysfunction following dietary salt, including in Black adults. Furthermore, recent work proposes the role of racial differences in exposure to social determinants of health, and differences in health behaviors that may influence risk of salt sensitivity. Physiological and environmental factors contribute to the mechanisms that manifest in racial differences in salt-sensitive blood pressure. Using this information, additional work is needed to develop strategies that can attenuate racial disparities in salt-sensitive blood pressure.

Mediating effect of body fat percentage in the association between ambient particulate matter exposure and hypertension: a subset analysis of China hypertension survey

BackgroundHypertension caused by air pollution exposure is a growing concern in China. The association between air pollutant exposure and hypertension has been found to be potentiated by obesity, however, little is known about the processes mediating this association. This study investigated the association between fine particulate matter (aerodynamic equivalent diameter ≤ 2.5 microns, PM2.5) exposure and the prevalence of hypertension in a representative population in southern China and tested whether obesity mediated this association.MethodsA total of 14,308 adults from 48 communities/villages in southern China were selected from January 2015 to December 2015 using a stratified multistage random sampling method. Hourly PM2.5 measurements were collected from the China National Environmental Monitoring Centre. Restricted cubic splines were used to analyze the nonlinear dose-response relationship between PM2.5 exposure and hypertension risk. The mediating effect mechanism of obesity on PM2.5-associated hypertension was tested in a causal inference framework following the approach proposed by Imai and Keele.ResultsA total of 20.7% (2966/14,308) of participants in the present study were diagnosed with hypertension. Nonlinear exposure-response analysis revealed that exposure to an annual mean PM2.5 concentration above 41.8 µg/m3 was associated with increased hypertension risk at an incremental gradient. 9.1% of the hypertension burden could be attributed to exposure to elevated annual average concentrations of PM2.5. It is noteworthy that an increased body fat percentage positively mediated 59.3% of the association between PM2.5 exposure and hypertension risk, whereas body mass index mediated 34.3% of this association.ConclusionsThis study suggests that a significant portion of the estimated effect of exposure to PM2.5 on the risk of hypertension appears to be attributed to its effect on alterations in body composition and the development of obesity. These findings could inform intersectoral actions in future studies to protect populations with excessive fine particle exposure from developing hypertension.

Assessing body mass index stages, individual diabetes and hypertension history effects on the risk of developing hypertension among Ghanaians: A cross-sectional study.

This study aimed to understand the relationship between body mass index (BMI),diabetes and hypertension history, and other risk of hypertension among Ghanaians. The BMI data are categorized according to the World Health Organization (WHO) definition. The data were obtained from the WHO Study on global AGEing and adult health (WHO SAGE) Ghana Wave 2. Descriptive statistics were used to summarize the variables, and the association between these variables and hypertension was assessed using the χ². Multivariable logistic regression was used to examine the relationship between hypertension and different BMI levels and other variables. Obesity class II individuals have about a 4-fold higher risk of developing hypertension compared to underweight individuals. Obesity class III, class I, and preobesity individuals have approximately a 3-fold higher risk. Normal weight is associated with increased hypertension risk. Both males and females show a significant increase in hypertension risk across all BMI categories. History of hypertension is linked to a 2.2-fold increased risk. Diabetes history is associated with hypertension when considering other factors. Elevated hypertension risk is observed among married, divorced, and widowed males then never married males. Only widowed females showed an increased risk. Older age significantly increases hypertension risk, particularly in females. Vegetable servings reduce hypertension risk, while fruit servings are associated with an increased risk. Vigorous exercise increases hypertension risk, particularly in females. Regular check-ups are recommended for married, divorced, and widowed males, focusing on blood pressure (BP) levels. Regular exercise from young age helps lower BP in later years. Individuals with a history of hypertension should follow BP control measures. Encouraging the consumption of the right combination of vegetables and fruits can help lower BP. Female tobacco smoking should be strongly discouraged due to a 54% increased risk of developing hypertension.
