RESUMO

OBJECTIVE: This trial analyzes the effects of home-based isometric handgrip training (IHT) and aerobic exercise training (AET) on ambulatory and office blood pressure (BP) in older adults with high normal to established hypertension. METHODS: This randomized controlled trial included 84 participants (46 women, 71.1 ± 3.6 years, systolic BP [SBP] 137.1 ± 13.8 mmHg, diastolic BP [DBP] 80.8 ± 8.3 mmHg). Participants were randomized into IHT (n = 28), AET (n = 28), or usual medical care plus lifestyle advice (UC, n = 28). Participants performed IHT or AET three times/week for 8 weeks. IHT consisted of 4 × 45 s bilateral contractions at 50% of maximum voluntary contraction with 1-min rest between sets. AET consisted of walking 30 min at 50%-70% of estimated maximum oxygen consumption. UC received standardized medical care including lifestyle advice. RESULTS: Seventy-six participants completed the intervention: 27 in IHT, 26 in AET, and 23 in UC. At baseline, BP values were similar among groups. No differences were observed in 24-h ambulatory, daytime, and nighttime SBP and DBP in any group (p > 0.05). IHT and AET reduced office SBP (-8.0 ± 13.4 mmHg; p = 0.004; -5.6 ± 12.2 mmHg; p = 0.027, respectively). IHT reduced office DBP (-3.3 ± 7.4 mmHg; p = 0.024), but AET did not. No differences occurred in office BP in UC. There was no difference in office BP among groups (p > 0.05). CONCLUSIONS: An 8-week home-based IHT and AET failed to reduce ambulatory SBP, while office SBP was reduced by 8/5 mmHg. Only IHT reduced office DBP by 3 mmHg. Thus, IHT and AET may be effective for lowering office BP in older adults with high normal to established hypertension.

RESUMO

This study evaluated the extent to which body mass index (BMI) mediates associations between risk factors and incident high blood pressure in American Indians and Alaska Natives (AI/ANs), Non-Hispanic Whites (NHWs), Non-Hispanic Blacks (NHBs) and Hispanics. There were 7,793 participants from the National Longitudinal Study of Adolescent to Adult Health: 312 AI/ANs, 1,091 Hispanics, 1,567 NHBs and 4,823 NHWs. Risk factors for high blood pressure included adolescent BMI, TV watching, fast-food consumption, smoking, parental obesity, parental educational attainment and financial instability. Relative risk regression models stratified by race/ethnicity were used to examine associations between risk factors and incident high blood pressure. Path analysis was used to assess mediation by BMI. Female sex was a protective factor against high blood pressure, and higher BMI was a risk factor in all populations. Smoking increased high blood pressure risk in AI/ANs (Incident Rate Ratio [IRR]: 1.14, 95% CI: 1.02-1.27), but not in other groups. BMI partially mediated the effect of parental obesity on high blood pressure in NHWs and completely mediated the effect of parental obesity in NHBs. In AI/ANs and Hispanics, BMI did not mediate the relationship between incident high blood pressure and any risk factor. This study assessed the extent to which BMI mediates risk factors for high blood pressure in four populations, and showed important differences across populations. Further research is needed to improve knowledge about relationships between BMI, risk factors and incident high blood pressure, and their potential variability by race/ethnicity.

RESUMO

(1) Background: High blood pressure (HBP), overweight, and obesity are common, growing public health problems worldwide. The aim of this study was to evaluate associations between changes in body weight status and HBP among Lithuanian children and adolescents during the COVID-19 pandemic. (2) Methods: In this study, we analysed data on blood pressure and anthropometric measurements of 2430 children and adolescents aged 8-18 years, who participated in both the baseline study conducted before the COVID-19 pandemic (from November 2019 to March 2020) and the follow-up study during the COVID-19 pandemic (from November 2021 to April 2022). Multivariate logistic regression analysis was used to estimate the associations between changes in weight status categories and HBP. (3) Results: At baseline, 17.1% of the subjects had overweight, 5.9% had obesity, 5.6% had abdominal obesity, and 23.7% had HBP, whereas at the follow-up, these percentages increased to 20.1%, 8.2%, 6.8%, and 27.4%, respectively. Compared to schoolchildren who maintained normal weight from baseline to the follow-up period, subjects who newly developed overweight/obesity and those who remained with persistent overweight/obesity had increased odds of HBP, with adjusted odds ratios (aORs) of 1.95 (p < 0.001) and 2.58 (p < 0.001), respectively. In subjects who transitioned from overweight/obesity to normal weight, the odds of HBP were slightly increased, with an aOR of 1.14 (p = 0.598), but the change was not statistically significant (p > 0.05). (4) Conclusions: This study observed an increase in the prevalence of overweight, obesity, and HBP among schoolchildren during the COVID-19 pandemic. The study also suggested that changes from normal body weight status at baseline to overweight/obesity during follow-up, especially persistent overweight/obesity, were associated with higher odds of HBP in Lithuanian children and adolescents during the COVID-19 pandemic.

RESUMO

BACKGROUND: Hypertension affects 26.7% of Pakistan's population, with only 6% achieving control. This study investigates antihypertensive medication adherence in Multan, focusing on socioeconomic and patient-related factors influencing non-adherence to study the lack of adherence to antihypertensive medications in hypertensive patients and its associated factors at Nishtar Hospital in Multan, Pakistan. METHODS: This cross-sectional study was conducted among hypertensive patients admitted at Nishtar Hospital Multan, Pakistan. Patients under the age of 20 years were excluded from the study. A self-developed questionnaire was used to gather the demographic details of patients. The Hill-Bone Medication Adherence Scale was used via a non-probability convenience sampling technique to deduce the adherence level in patients. Data analysis was done using SPSS (Statistical Package for the Social Sciences) v23 (IBM Corp., Armonk, NY). p-value < 0.05 was considered significant. RESULTS: Out of 217 respondents, most were female, married, unemployed, and residing in urban areas. Most of them had a higher level of education and a monthly income averaging below 30,000 PKR (Pakistani Rupee). The insight into the hypertensive history showed that most of them had a positive family history and comorbid conditions, and were hypertensive for more than five years. The majority of the patients had a complex regimen prescribed to them with multiple doses throughout the day. The minority were smokers and had medications provided to them for free, through public or government-funded institutions. More importantly, adherence to the antihypertensive therapy was negatively correlated with the age of the patients (p = 0.004, r = -0.195), complexity of regimen (p = 0.041), multiple dosing (p = 0.039), and cost of medication (p = 0.043). All of these relations were statistically significant. CONCLUSION: Lack of adherence to antihypertensive medications in hypertensive patients is more common in populations belonging to older age groups, complex regimens, multiple doses, and higher medicine fees.

RESUMO

BACKGROUND: Adolescence is a vulnerable phase when risky behaviours like smoking, poor diet, and physical inactivity set the stage for health problems like hypertension. OBJECTIVE: This study assessed the prevalence of high blood pressure (HBP) and associated factors among apparently healthy inschool adolescents in Delta State, Nigeria. METHODS: A cross-sectional study was conducted among apparently healthy in-school adolescents aged 10 to 19 years, using a multi-stage random sampling technique. HBP was defined using the 2016 European Society of Hypertension Guidelines. Factors associated with HBP were determined using binary logistic regression. A p-value less than 0.05 was taken as significant. RESULTS: Of the 574 participants surveyed, 331 (57.7%) were females and 243 (42.3%) were males, with a female-to-male ratio of 1.36. The mean age of the study participants was 14.7 years. The mean systolic and diastolic blood pressure of the study participants were 118.81 (±12.703) and 70.16 (±9.972) mmHg respectively. Prehypertension and hypertension were present in 14.8% and 18.3% of the study population, respectively. Age 10-13 years (AOR = 7.70; 95% CI: 2.26-26.22; p = 0.001) and 14-16 years (AOR = 4.62; 95% CI: 1.40 -15.25; p = 0.001), upper socioeconomic status (AOR=1.19; 95% CI: 0.57-2.48; p = 0.020), and obesity (AOR = 2.14; 95% CI: 1.08-4.25; p = 0.039) were factors associated with HBP. CONCLUSION: The prevalence of hypertension among the study participants was significant. Factors associated with HBP include younger age (specifically 10-16 years old), higher socioeconomic status, and obesity.


CONTEXTE: L'adolescence est une phase vulnérable où des comportements à risque tels que le tabagisme, une alimentation déséquilibrée et l'inactivité physique posent les bases de problèmes de santé comme l'hypertension. OBJECTIF: Cette étude a évalué la prévalence de l'hypertension artérielle (HTA) et les facteurs associés chez des adolescents scolarisés apparemment en bonne santé dans l'État du Delta, Nigéria. MÉTHODES: Une étude transversale a été menée parmi des adolescents scolarisés apparemment en bonne santé âgés de 10 à 19 ans, en utilisant une technique d'échantillonnage aléatoire à plusieurs degrés. L'HTA a été définie selon les directives de 2016 de la Société Européenne d'Hypertension. Les facteurs associés à l'HTA ont été déterminés à l'aide d'une régression logistique binaire. Une valeur p inférieure à 0,05 a été considérée comme significative. RÉSULTATS: Parmi les 574 participants interrogés, 331 (57,7 %) étaient des filles et 243 (42,3 %) des garçons, avec un ratio fille/garçon de 1,36. L'âge moyen des participants à l'étude était de 14,7 ans. La pression artérielle systolique et diastolique moyennes des participants étaient respectivement de 118,81 (±12,703) et 70,16 (±9,972) mmHg. La préhypertension et l'hypertension étaient présentes chez 14,8 % et 18,3 % de la population étudiée, respectivement. L'âge de 10 à 13 ans (ORaj = 7,70 ; IC à 95 % : 2,26-26,22 ; p = 0,001) et de 14 à 16 ans (ORaj = 4,62 ; IC à 95 % : 1,40-15,25 ; p = 0,001), un statut socio-économique élevé (ORaj = 1,19 ; IC à 95 % : 0,57-2,48 ; p = 0,020) et l'obésité (ORaj = 2,14 ; IC à 95 % : 1,08-4,25 ; p = 0,039) étaient des facteurs associés à l'HTA. CONCLUSION: La prévalence de l'hypertension parmi les participants à l'étude était significative. Les facteurs associés à l'HTA incluent un âge plus jeune (en particulier entre 10 et 16 ans), un statut socio-économique élevé et l'obésité. MOTS-CLÉS: Adolescents, Hypertension artérielle, Obésité.

RESUMO

AIM: The aim was to investigate whether COVID-19 increases new incidence of hypertension (HTN), chronic kidney disease (CKD) and diabetic ketoacidosis (DKA) in patients with type 1 diabetes (T1D) up to 40 months post-infection. MATERIALS AND METHODS: Three groups of patients from the Montefiore Health System in the Bronx (1 March 2020 to 1 July 2023) were studied: T1D patients hospitalized for COVID-19 (H-COVID-19, n = 511), T1D patients with COVID-19 but not hospitalized for COVID-19 (NH-COVID-19, n = 306) and T1D patients without a positive COVID-19 test on record (non-COVID-19, n = 1547). COVID-19 patients were those with a positive polymerase-chain-reaction test on record, and non-COVID-19 patients were either tested negative or not tested on record. Cumulative incidences and adjusted hazard ratios (aHR) with 95% confidence intervals (CI) were computed with adjustment for competing risks. RESULTS: Compared to non-COVID-19 patients, both H-COVID-19 (unadjusted 19.72% vs. 3.14%, p < 0.001; aHR = 7.55 [3.33, 17.06], p < 0.001) and NH-COVID-19 (10.26% vs. 3.14%, p = 0.004; aHR = 5.08 [2.19, 11.78], p < 0.001) patients were more likely to develop new HTN. Compared to non-COVID-19 patients, both H-COVID-19 (11.41% vs. 1.14%, p < 0.001; aHR = 9.76 [4.248, 22.25], p < 0.001) and NH-COVID-19 (7.69% vs. 1.14%, p < 0.001; aHR = 6.54 [2.91, 14.67], p < 0.001) patients were more likely to develop new CKD. Compared to non-COVID-19 patients, both H-COVID-19 (4.09% vs. 1.06%, p < 0.001; aHR = 12.24 [4.09, 36.59], p < 0.001) and NH-COVID-19 (3.06% vs. 1.06%, p = 0.035; aHR = 12.94 [4.09, 40.89], p < 0.001) patients were more likely to develop new DKA at follow-up. CONCLUSION: T1D patients with COVID-19 are at higher risk of developing new HTN, CKD and DKA compared to T1D patients without COVID-19.

RESUMO

BACKGROUND: High blood pressure (HBP) and diabetes mellitus (DM) are two of the most prevalent cardiometabolic disorders globally, especially among individuals with lower socio-economic status (SES). Studies have linked residential greenness to decreased risks of HBP and DM. However, there has been limited evidence on whether SES may modify the associations of residential greenness with HBP and DM. METHODS: Based on a national representative cross-sectional study among 44,876 adults, we generated the normalized difference vegetation index (NDVI) at 1 km spatial resolution to characterize individuals' residential greenness level. Administrative classification (urban/rural), nighttime light index (NLI), individual income, and educational levels were used to characterize regional urbanicity and individual SES levels. RESULTS: We observed weaker inverse associations of NDVI with HBP and DM in rural regions compared to urban regions. For instance, along with per interquartile range (IQR, 0.26) increment in residential NDVI at 0∼5 year moving averages, the ORs of HBP were 1.04 (95%CI: 0.94, 1.15) in rural regions and 0.85 (95%CI: 0.79, 0.93) in urban regions (P = 0.003). Along with the decrease in NLI levels, there were continuously decreasing inverse associations of NDVI with DM prevalence (P for interaction <0.001). In addition, weaker inverse associations of residential NDVI with HBP and DM prevalence were found among individuals with lower income and lower education levels compared to their counterparts. CONCLUSIONS: Lower regional urbanicity and individual SES could attenuate the associations of residential greenness with odds of HBP and DM prevalence.

RESUMO

BACKGROUND: Over half of adults from rural South Africa are hypertensive. Apart from pharmaceutical treatment, lifestyle changes such as increasing physical activity and reducing dietary salt have been strongly advocated for the control of hypertension. However, the control rates of hypertension for adults in rural South Africa are low. In this paper we explore whether this is due to the recommended lifestyle intervention not aligning with the individual's socio-cultural determinants of behaviour change. AIM: To explore the social and cultural beliefs, perceptions and practices regarding physical activity and diet as a hypertension control intervention on hypertensive adults living in a rural sub-district in South Africa. METHODS: Nine focus group discussions were conducted with hypertensive adults aged 40 years and above from Bushbuckridge sub-district in Mpumalanga Province of South Africa using a semi-structured interview guide. Each session began with introductions of the discussion theme followed by a short discussion on what the participants know about hypertension and the normal blood pressure readings. Physical activity and dietary habits were then introduced as the main subject of discussion. Probing questions were used to get more insight on a specific topic. A thematic analysis approach was used to generate codes, categories, and themes. A manual approach to data analysis was chosen and data obtained through transcripts were analysed inductively. FINDINGS: Participants had a lack of knowledge about blood pressure normal values. Perceived causes of hypertension were alluded to psychosocial factors such as family and emotional-related issues. Physical activity practices were influenced by family and community members' attitudes and gender roles. Factors which influenced dietary practices mainly involved affordability and availability of food. To control their hypertension, participants recommend eating certain foods, emotional control, taking medication, exercising, praying, correct food preparation, and performing house chores. CONCLUSION: Lifestyle interventions to control hypertension for adults in a rural South African setting using physical activity promotion and dietary control must consider the beliefs related to hypertension control of this population.

RESUMO

Hypertension is a disease associated with epigenetic aging. However, the pathogenic mechanism underlying this relationship remains unclear. We aimed to characterize the shared genetic architecture of hypertension and epigenetic aging, and identify novel risk loci. Leveraging genome-wide association studies (GWAS) summary statistics of hypertension (129,909 cases and 354,689 controls) and four epigenetic clocks (N = 34,710), we investigated genetic architectures and genetic overlap using bivariate casual mixture model and conditional/conjunctional false discovery rate methods. Functional gene-sets pathway analyses were performed by functional mapping and gene annotation (FUMA) protocol. Hypertension was polygenic with 2.8 K trait-influencing genetic variants. We observed cross-trait genetic enrichment and genetic overlap between hypertension and all four measures of epigenetic aging. Further, we identified 32 distinct genomic loci jointly associated with hypertension and epigenetic aging. Notably, rs1849209 was shared between hypertension and three epigenetic clocks (HannumAge, IEAA, and PhenoAge). The shared loci exhibited a combination of concordant and discordant allelic effects. Functional gene-set analyses revealed significant enrichment in biological pathways related to sensory perception of smell and nervous system processes. We observed genetic overlaps with mixed effect directions between hypertension and all four epigenetic aging measures, and identified 32 shared distinct loci with mixed effect directions, 25 of which were novel for hypertension. Shared genes enriched in biological pathways related to olfaction.

RESUMO

INTRODUCTION: Hypertension is a widespread and life-threatening condition globally, with its prevalence increasing rapidly, particularly among adults. This study aims to examine the trend in adult hypertension prevalence and associated risk factors in both urban and rural areas of Bangladesh from 2011 to 2018. METHODS: Nationally representative cross-sectional data from the Bangladesh Demographic and Health Survey was used at two time points, 2011 and 2018. In our study, we used a two-step approach for variable selection, combining traditional statistical methods ( χ 2 test) with a machine learning algorithm (Boruta algorithm).. This study also employed two different multivariate binary logistic regression models to identify the risk factors that are most closely connected to the presence of hypertension (respectively for urban and rural locations). RESULTS: According to the study, hypertension has been on the rise in Bangladesh. In 2011, over a third of adults (38.7%) in urban Bangladesh had hypertension, a number that rose by 22.6% in 2017-18. Though rural areas had a lower hypertension prevalence in 2011 (36%), it surged to 64% in 2017-18, surpassing the rate in urban areas. The results of the multivariate analysis showed that age, gender, education, wealth status, area, and survey year had a significant influence on the determinants of hypertension status in connection to place of residence. According to the odds ratio, the prevalence was significantly higher among older respondents, female respondents, wealthy families and higher-educated respondents. CONCLUSION: A large proportion of Bangladesh's adult population suffers from hypertension. A health education program is required to develop appropriate strategies, including appropriate weight control, appropriate physical activity, and healthier eating habits. Health authorities should take initiatives to spread awareness among people, particularly at an older age.

RESUMO

Blood pressure or flow measurements have been associated with vascular health and cognitive function. We proposed that energetic hemodynamic parameters may provide a more nuanced understanding and stronger correlation with cognitive function, in comparisons with conventional aortic and carotid pressure and flow parameters. The study comprised 1858 participants, in whom we assessed cognitive function via MoCA method, and measured central aortic and carotid pressure and flow waveforms. In addition to various pressure and flow parameters, we calculated energetic hemodynamic parameters through integration of pressure multiplying flow with respect to time. Energetic hemodynamic parameters, particularly aortic and carotid mean and pulsatile energy and pulsatility index (PI), were significantly associated with MoCA score more than any aortic and carotid pressure and flow parameters, after adjusting for age, sex, education, depression score, heart rate, BMI, HDL-cholesterol, and glucose levels. MoCA exhibited a strong positive relationship with carotid mean energy (standardized beta = 0.053, P = 0.0253) and a negative relationship with carotid energy PI (standardized beta = -0.093, P = 0.0002), exceeding the association with all traditional pressure- or flow-based parameters. Aortic pressure reflection coefficient at the aorto-carotid junction was positively correlated with mean carotid energy and negatively correlated with PI. Aortic characteristic impedance positively correlated with carotid energy PI but not mean energy. Our research indicates that energetic hemodynamic parameters, particularly carotid mean energy and carotid energy PI, have a stronger association with MoCA scores than traditional pressure- or flow-based metrics. This correlation with cognitive function is notably influenced by the properties of the aorto-carotid interface.

RESUMO

Magnesium (Mg), an essential nutrient with a wide area of physiological roles, stands as a cofactor in over 600 enzymatic reactions involved in the synthesis of proteins and nucleic acids, DNA repair, neuromuscular functions, neuronal transmission, cardiac rhythm regulation, and the modulation of metabolic pathways, as well as acting as a natural blocker for the calcium channels. Our objective was to highlight the most recent clinical data with respect to daily Mg intake (DMI) and metabolic traits, particularly type 2 diabetes mellitus (DM). This was a PubMed-based review of the English-language medical papers across different key terms of search; the time frame was from January 2019 until April 2024. We included (clinically relevant) original studies and excluded cases reports, series, reviews, editorials, opinion, experimental studies, and non-human data as well as studies that did not specifically assessed DMI and only provided assays of serum Mg, studies on patients diagnosed with type 1 or secondary DM. A total of 30 studies were included and we organized the key findings into several sections as follows. Studies investigating DMI in relationship with the adherence to local recommendations in diabetic subjects (n = 2, one transversal and another retrospective cohort; N = 2823) found that most of them had lower DMI. Deficient DMI was correlated with the risk of developing/having DM across five studies (n = 5, one prospective and four of cross-sectional design; N = 47,166). An inverse correlation between DMI and DM prevalence was identified, but these data are presented amid a rather heterogeneous spectrum. Four novel studies (N = 7279) analysed the relationship between DMI and DM control according to various methods (HbA1c, fasting and postprandial glycaemia, and insulin); the association may be linear in diabetic subjects only at certain levels of DMI; additionally, the multifactorial influence on HBA1c should take into consideration this dietary determinant, as well, but there are no homogenous results. Three studies concerning DMI and diabetic complications (one cross-sectional, one prospective, and another case-control study) in terms of retinopathy (n = 1, N = 3794) and nephropathy (n = 2, N = 4805) suggested a lower DMI was associated with a higher risk of such complications. Additionally, two other studies (one prospective and one retrospective cohort) focused on mortality (N = 6744), which, taking only certain mortality indicators into consideration, might be decreased in the subgroups with a higher DMI. Seven studies (N = 30,610) analysed the perspective of DMI in the general population with the endpoint of different features amid glucose profile, particularly, insulin resistance. Concerning HOMA-IR, there were three confirmatory studies and one non-confirmatory, while fasting plasma glucose was highlighted as inversely correlated with a DMI (n = 1). The highest level of evidence regarding Mg supplementation effects on glucose metabolism stands on seven randomised controlled trials (N = 350). However, the sample size was reduced (from 14 to 86 individuals per study, either diabetic or pre-diabetic) and outcomes were rather discordant. These clinical aspects are essential from a multidisciplinary perspective and further trials are mandatory to address the current areas of discordant results.

RESUMO

Background Since bilateral nasal packing entails nasal and airway obstruction, this practice consequently leads to oral breathing. The resulting hypoxemia may then negatively impact vital signs, including blood pressure (BP), blood oxygen saturation (SpO2), and heart rate (HR). These systemic effects have a detrimental effect on patients. Objective The objective of this study is to observe the effects of bilateral nasal packing on patients' post-operative vital signs. Materials and methods This prospective study was conducted in the department of otolaryngology - head and neck surgery over a six-month period. The study included 83 post-operative patients with nasal surgery, in which bilateral merocele nasal packing was performed. The patients' pulse oximetry, systolic and diastolic BP, and HR were recorded four times the night before and after surgery. A statistical analysis was performed, and the mean values, standard deviation, and range were calculated. A paired sample t-test was also applied. The results are presented in figures and tables. Results The mean age of the participants was 27.65 ± 10.72 years, and 56 (67.5%) were male. Septoplasty was the most common surgery performed, with 63 participants having undergone this procedure (75.9%). When the pre-operative mean values of systolic and diastolic BP, SpO2, and HR were compared with the post-operative mean values, when a bilateral nasal pack was in place, a significant increase was found in all, with a p-value of <0.001 in each. Conclusion Bilateral nasal packing affects patients' vital signs by significantly increasing diastolic and systolic BP and decreasing SpO2. The HR is also significantly increased when packing is in place.

RESUMO

BACKGROUND: The Dietary Approaches to Stop Hypertension (DASH) diet has been shown to reduce blood pressure in hypertensive adults, but there is limited information available on dietary adherence and related factors among hypertensive patients in the study area. Hence, the current study aimed to assess dietary adherence and associated factors among hypertensive patients aged greater than or equal to 18 years old in governmental hospitals of Guji zone, Oromia region, Ethiopia. METHODS: A facility-based cross-sectional study was conducted between June 5, 2023, and August 30, 2023. For this study, patients with a systolic blood pressure of 140 mmHg or higher and/or a diastolic blood pressure of 90 mmHg or higher on two separate occasions were classified as hypertensive. Thus, the study involved 399 hypertensive patients who were selected using systematic random sampling methods. The level of knowledge regarding hypertension was measured through the use of hypertension knowledge-level scale (HK-LS) questionnaires, while the reliability and validity of the questionnaire were assessed using the Cronbach's alpha test (α ≥ 0.70).The association between factors was analyzed using adjusted odds ratio (AOR) and a 95% confidence interval. Variables with p-values below 0.05 were considered statistically significant. RESULTS: Among the respondents, only 28.30% (CI: 23.9, 33) of participants were found to be adherent to the recommended diet. Factors like participation in nutritional education, level of knowledge, respondents' ages, and length of time since hypertension diagnosis showed a strong association with adherence to recommended dietary guidelines. CONCLUSIONS: The research findings indicated that the level of compliance with the prescribed diet was generally subpar among individuals with hypertension in comparison to the Dietary Approaches to Stop Hypertension (DASH) diet recommendations. So, it is essential to offer hypertensive patients an education focused on health and nutrition in order to enhance their adherence to dietary guidelines and promote a healthier dietary routine. The results of this research will also be valuable in increasing awareness among policymakers and the general public about the dietary adherence and its associated factors, thus aiding in the development and execution of suitable interventions.

RESUMO

BACKGROUND: Understanding the association between hypertension prevalence and socioeconomic and behavioral variables during a pandemic is essential, and this analysis should extend beyond short-term trends. OBJECTIVE: This study aims to examine long-term trends in the prevalence of participants diagnosed with and receiving treatment for hypertension, using data collected by a nationally representative survey from 2009 to 2022, which includes the COVID-19 pandemic era. METHODS: A nationwide, population-based, cross-sectional study used data collected from the South Korea Community Health Survey between 2009 and 2022. The study sample comprised 3,208,710 Korean adults over a period of 14 years. We aimed to assess trends in the prevalence of participants diagnosed with and receiving treatment for hypertension in the national population from 2009 to 2022, with a specific focus on the COVID-19 pandemic, using weighted linear regression models. RESULTS: Among the included 3,072,546 Korean adults, 794,239 (25.85%) were aged 19-39 years, 1,179,388 (38.38%) were aged 40-59 years; 948,097 (30.86%) were aged 60-79 years, and 150,822 (4.91%) were aged 80 years or older. A total of 1,426,379 (46.42%) were men; 761,896 (24.80%) and 712,264 (23.18%) were diagnosed with and received treatment for hypertension, respectively. Although the overall prevalence over the 14-year period increased, the upward trends of patients diagnosed with and receiving treatment for hypertension decreased during the COVID-19 pandemic era compared with the prepandemic era (ß difference for trend during vs before the pandemic -.101, 95% CI -0.107 to -0.094 vs -.133, 95% CI -0.140 to -0.127). Notably, the trends in prevalence during the pandemic were less pronounced in subgroups of older adults (≥60 years old) and individuals with higher alcohol consumption (≥5 days/month). CONCLUSIONS: This nationwide representative study found that the national prevalence of participants diagnosed with and receiving treatment for hypertension increased during the prepandemic era. However, there was a marked decrease in these trends during the prepandemic era, compared with the pandemic era, particularly among specific subgroups at increased risk of negative outcomes. Future studies are needed to evaluate the factors associated with changes in the prevalence of hypertension during the COVID-19 pandemic.

RESUMO

Left ventricular hypertrophy (LVH) is often used as an indicator to assess hypertension-mediated organ damage (HMOD), alongside hypertensive retinopathy (HR) and nephropathy. Assessment of HMOD is crucial when making decisions about treatment optimization. Despite longstanding debate over its reliability to detect LVH, it is common practice to perform an electrocardiogram (ECG) instead of directly assessing left ventricular mass with echocardiography. In this study, the presence of LVH was evaluated using both ECG and echocardiography among consecutive patients suspected of therapy-resistant hypertension or secondary hypertension in the outpatient clinic of the Department of Internal Medicine at the Diakonessen Hospital, Utrecht, the Netherlands, between July 15, 2017, and July 31, 2020. The primary endpoints were the specificity and sensitivity of ECG as a diagnostic tool for LVH, with echocardiography serving as the reference method. Among the 329 participants, we identified 70 individuals (21.3%) with true LVH based on echocardiography. The ECG displayed a sensitivity of 47.9% and a specificity of 75.3%. Moreover, the area under the receiver operating characteristics curve was 0.604. In conclusion, ECG demonstrates limited value in identifying LVH. Considering the importance of accurately assessing HMOD for treatment optimization of hypertension, the role of ECG as a diagnostic tool for LVH is, therefore, questionable. Instead, we recommend employing standard echocardiography as a more reliable diagnostic.

RESUMO

Fibromuscular dysplasia (FMD) is a disease of the musculature of arterial walls leading to stenoses, aneurysms, and dissections. The purpose of this report was to summarize the evidence for (1) one-time routine imaging from brain-to-pelvis and (2) lifelong antiplatelet therapy, for example, aspirin, for patients diagnosed with FMD as suggested by an international consensus report from 2019. PubMed was systematically searched, and the evidence providing a basis for the current consensus points, as well as articles published since, were reviewed. In four registries evaluating patients with FMD, the prevalence of multivessel involvement, aneurysms, and dissections was reported to be 43.5%-66.3%, 21.6%-30.6%, and 5.6%-28.1%, respectively. Any antiplatelet drug was used in 72.9% of patients, and aspirin was prescribed in up to 70.2% of patients. Based on the high prevalence of vascular manifestations, their associated morbidity, and the potential for endovascular or surgical intervention, the suggestion of one-time brain-to-pelvis screening with computed tomography angiography or magnetic resonance angiography is well supported. Contrarily, the evidence to support the consensus statement of lifelong antiplatelet therapy to all patients in the absence of contraindications is more uncertain since a beneficial effect has not been demonstrated specifically in patients with fibromuscular dysplasia. Therefore, until the efficacy and safety of primary thromboprophylaxis have been demonstrated in this patient group specifically, it may be equally appropriate to only use antiplatelet agents in patients with a clear indication after individual evaluation according to risk factors for thrombotic and thromboembolic complications.

RESUMO

Background: Addressing dietary factors to lower blood pressure can be a crucial strategy at the population level to mitigate the risk of hypertension. In a prior investigation, a tailored food score was used as a dietary index relevant to hypertension among Korean adults. This current study aims to assess the association between the overall quality of the diet, taking into account more precise food components, and evaluate the risk of developing hypertension. Methods: This prospective cohort study included 5,342 adults aged 40-70 without hypertension who participated in the Korean Genome and Epidemiology Study (KoGES) from 2001 to 2016. The improved Recommended Food Score for Hypertension (iRFSH) is a modified version of the Recommended Food Score to assess the consumption of foods recommended in the Dietary Approaches to Stop Hypertension (DASH) diet for Korean foods. A higher score reflects greater consumption of recommended foods, indicative of higher dietary quality. The maximum total score is 65. High blood pressure, which includes both hypertension and prehypertension, was analyzed using Cox proportional hazard regression models to examine its prospective relationship with iRFSH. Results: Among 2,478 males and 2,864 females with 10.8 mean years of follow-up, a higher score of iRFSH was associated with a lower risk of hypertension in the highest quintile compared to the lowest quintile [total: hazard ratio (HR): 0.79; 95% confidence interval (CI): 0.72, 0.87; female: HR: 0.71; 95% CI: 0.62, 0.83]. Conclusion: Higher iRFSH is associated with a lower incidence of hypertension. Our results suggest that the iRFSH may be a potential tool for assessing dietary quality and dietary patterns and predicting the risk of hypertension in Korean adults.

RESUMO

Background: 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. Methodology: 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. Results: 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. Conclusion: 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.

RESUMO

Background: Hypertension continues to pose a significant burden on the health systems in Sub-Saharan Africa (SSA). Multiple challenges at the health systems level could impact patients' blood pressure outcomes. There is a need to understand the gaps in health systems to improve their readiness to manage the rising burden of hypertension Objective: To explore health system barriers and opportunities for improved management of hypertension in Ghana, West Africa. Methods: We conducted 5 focus group discussions involving 9 health facility leaders and 24 clinicians involved in hypertension treatment at 15 primary-level health facilities in Kumasi, Ghana. We held discussions remotely over Zoom and used thematic analysis methods. Results: Four themes emerged from the focus group discussions: (1) financial and geographic inaccessibility of hypertension services; (2) facilities' struggle to maintain the supply of antihypertensive medications and providers' perceptions of suboptimal quality of insured medications; (3) shortage of healthcare providers, especially physicians; and (4) patients' negative self-management practices. Facilitators identified included presence of wellness and hypertension clinics for screening and management of hypertension at some health facilities, nurses' request for additional roles in hypertension management, and the rising positive practice of patient home blood pressure monitoring. Conclusion: Our findings highlight critical barriers to hypertension service delivery and providers' abilities to provide quality services. Health facilities should build on ongoing innovations in hypertension screening, task-shifting strategies, and patient self-management to improve hypertension control. In Ghana and other countries, policies to equip healthcare systems with the resources needed for hypertension management could lead to a high improvement in hypertension outcomes among patients.
