We focused on investigating the factors related with the quality of life and depression symptomatology in patients with type 2 diabetes.Participants and methods: A total of 173 Mexican patients with type 2 diabetes were recruited. An interview face-to-face, a sociodemographic characteristics questionnaire, the Short Form 36 (SF-36), and the Clinical Epidemiological Studies of Depression were applied. The biochemical parameters measured were blood glucose, cholesterol, triacylglycerol levels, and glycated hemoglobin.Results: In all SF-36 subscales, female patients had lower scores in comparison with male patients; individuals ≥65 years of age showed less physical function. We observed that married patients presented a better quality of life than people who were widowed or divorced (P

The Mediterranean diet (MD) plays an important role in delaying vascular aging. The main objective of this study was to analyze the association between adherence to the MD and vascular aging estimated with brachial-ankle pulse wave velocity (ba-PWV) in a Spanish population sample and the differences by sex., Methods: Cross-sectional descriptive study. A total of 3437 subjects from the EVA, MARK and EVIDENT studies participated. The ba-PWV was assessed with the Vasera VS-1500 ® device. Vascular aging was classified as healthy vascular aging (HVA), normal vascular aging (NVA) and early vascular aging (EVA) and adherence to the MD was assessed with the Mediterranean Diet Adherence Screener questionnaire., Results: The mean age was 60.15 ± 9.55 (60.09 ± 9.71 in women; 60.20 ± 9.43 in men). Overall, MD adherence was observed in 48.0% of subjects (40% in women; 54% in men). The mean value of ba-PWV was 14.38 ± 2.71 (women 14.24 ± 2.89; men 14.49 ± 2.56). In multinomial logistic regression a positive association was found overall between HVA and NVA (OR = 1.751, 95% CI: 1.411-2.174, p < 0.001) and between HVA and EVA (OR = 1.501, 95% CI:1.295-1.740, p < 0.001); in women between HVA and NVA (OR = 2. 055, 95% CI:1.456-2.901, p < 0.001) and between HVA and EVA (OR = 1.413, 95% CI:1.124-1.776; p = 0.003); and in men between HVA and NVA (OR = 1.551, 95% CI: 1.175-2.047, p = 0.002) and between HVA and EVA (OR = 1.549, 95% CI: 1.275-1.882; p < 0.001)., Conclusions: The results of this work indicate that greater adherence to the MD is associated with healthier vascular aging.

Objectives: The aim of the study was to examine the relationship between the Mediterranean diet (MD) and vascular stiffness and metabolic syndrome (MetS), as well as its components in individuals over the age of 65, overall and by sex., Methods: The subjects of the study were people over 65 years of age, with a full record of all variables analyzed from the EVA, MARK, and EVIDENT studies. Data from 1280 subjects with a mean age of 69.52 ± 3.58 years (57.5% men) were analyzed. The MD was recorded with the validated 14 item MEDAS questionnaire. MetS was defined following the guidelines of the joint scientific statement from the Programa Nacional de Educación sobre el Colesterol III. Vascular stiffness was evaluated with the VaSera VS-1500 ® device by measuring the cardio-ankle vascular index (CAVI) and the brachial-ankle pulse wave velocity (baPWV)., Results: The mean MEDAS score was 6.00 ± 1.90, (5.92 ± 1.92 in males, 6.11 ± 1.88 in females; p = 0.036). CAVI: 9.30 ± 1.11 (9.49 ± 1.05 males, 9.03 ± 1.13 females; p = <0.001). baPWV: 15.82 ± 2.56 (15.75 ± 2.46 males, 15.92 ± 2.68 females; p = <0.001). MetS was found in 51% (49% males, 54% females; p = 0.036). Subjects with MetS had lower MD adherence and higher vascular stiffness values than subjects without MetS. Overall, we found a negative association with MD score and the number of MetS components (β = -0.168), with glycemia (β = -0.007), triglycerides (β = -0.003), waist circumference (β = -0.018), CAVI (β = -0.196) and baPWV (β = -0.065), and a positive association with HDL cholesterol (β = 0.013). Regarding sex, associations followed the same direction but without reaching statistical significance with blood glucose and triglycerides in females and with HDL cholesterol and waist circumference in males., Conclusions: The results indicate that greater adherence to the Mediterranean diet decreases vascular stiffness and the percentage of subjects with MetS, although results differed in the association with MetS components by sex.

Latent autoimmune diabetes in adults (LADA) is characterized by the presence of glutamate decarboxylase autoantibodies (GADA). LADA has intermediate features between type 1 diabetes and type 2 diabetes. In addition, genetic risk factors for both types of diabetes are present in LADA. Nonetheless, evidence about the genetics of LADA in non-European populations is scarce. This study aims to perform a genome-wide association study with a phenome-wide association study of LADA in a southeastern Mexican population. We included 59 patients diagnosed with LADA from a previous study and 3121 individuals without diabetes from the MxGDAR/ENCODAT database. We utilized the GENESIS package in R to perform the genome-wide association study (GWAS) of LADA and PLINK for the phenome-wide association study (PheWAS) of LADA features. Nine polymorphisms reach the nominal association level (1 × 10 -5 ) in the GWAS. The PheWAS showed that rs7305229 is genome-wide and associated with serum GADA levels in our sample ( p = 1.84 × 10 -8 ). rs7305229 is located downstream of the FAIM2 gene; previous reports associate FAIM2 variants with childhood obesity, body mass index, body adiposity measures, lymphocyte CD8+ activity, and anti-thyroid peroxidase antibodies. Our findings reveal that rs7305229 affects the GADA levels in patients with LADA from southeastern Mexico. More studies are needed to determine if this risk genotype exists in other populations with LADA.

(1) The main aim of this study was to analyze the relationship of the Mediterranean diet (MD) with vascular function in participants with and without increased insulin resistance (IR) in the Spanish population. A secondary aim was to study differences by gender. (2) Methods: Data were analyzed from 3401 subjects in the EVA, MARK, and EVIDENT studies (mean age = 60 years and 57% men). IR was evaluated with the triglyceride and glucose index (TyG index). TyG index = Ln [(fasting triglyceride mg/dL × fasting glucose mg/dL)/2]. The MD was measured against the MEDAS questionnaire, with the 14 items used in the PREDIMED study. Vascular stiffness was estimated with the brachial-ankle pulse wave velocity (baPWV) and the cardio ankle vascular index (CAVI) using the Vasera VS-1500 ® . (3) Results: The mean MEDAS value was 5.82 ± 2.03; (men: 5.66 ± 2.06; women: 6.04 ± 1.99; p < 0.001). MD adherence was 36.8% (men: 34.2%; women: 40.3%; p < 0.001). The mean baPWV value was 14.39 ± 2.78; (men: 14.50 ± 2.65; women: 14.25 ± 2.93; p = 0.005). A baPWV value ≥ 14.5 m/s was found in 43.4% (men: 43.6%; women: 40.0%; p = 0.727). The mean CAVI value was 8.59 ± 1.28; (men: 8.75 ± 1.28; women: 8.37 ± 1.26; p < 0.001). CAVI values ≥ 9 were present in 39.0% (men: 44.4%; women: 31.7%; p < 0.001). The mean value of the TGC/G index was 10.93 ± 1.39; (men: 11.08 ± 1.33; women: 10.73 ± 1.43; p < 0.001). IR was found in 49.9%. The average value of the MD score value was negatively associated with baPWV and CAVI in all groups analyzed (<0.05), except in the group of women with insulin resistance. (4) Conclusions: The results suggest that MD adherence is negatively associated with the vascular stiffness parameters analyzed in all the groups studied except the group of women with insulin resistance.

Background: Gut microbiota and its by-products are increasingly recognized as having a decisive role in cardiovascular diseases. The aim is to study the relationship between gut microbiota and early vascular ageing (EVA)., Methods: A cross-sectional study was developed in Salamanca (Spain) in which 180 subjects aged 45-74 years were recruited. EVA was defined by the presence of at least one of the following: carotid-femoral pulse wave velocity (cf-PWV), cardio-ankle vascular index (CAVI) or brachial-ankle pulse wave velocity (ba-PWV) above the 90th percentile of the reference population. All other cases were considered normal vascular ageing (NVA)., Measurements: cf-PWV was measured by SphygmoCor® System; CAVI and ba-PWV were determined by Vasera 2000® device. Gut microbiome composition in faecal samples was determined by 16S rRNA Illumina sequencing., Results: Mean age was 64.4 ± 6.9 in EVA group and 60.4 ± 7.6 years in NVA (p < .01). Women in EVA group were 41% and 53% in NVA. There were no differences in the overall composition of gut microbiota between the two groups when evaluating Firmicutes/Bacteriodetes ratio, alfa diversity (Shannon Index) and beta diversity (Bray-Curtis). Bilophila, Faecalibacterium sp.UBA1819 and Phocea, are increased in EVA group. While Cedecea, Lactococcus, Pseudomonas, Succiniclasticum and Dielma exist in lower abundance. In logistic regression analysis, Bilophila (OR: 1.71, 95% CI: 1.12-2.6, p = .013) remained significant., Conclusions: In the studied Spanish population, early vascular ageing is positively associated with gut microbiota abundance of the genus Bilophila. No relationship was found between phyla abundance and measures of diversity., (© 2024 Stichting European Society for Clinical Investigation Journal Foundation. Published by John Wiley & Sons Ltd.)

The aim of this study was to analyze the relationship between healthy vascular aging (HVA) and the Mediterranean diet alongside other lifestyles in a Spanish population aged 35 to 75 years without previous cardiovascular diseases., Methods: In this cross-sectional descriptive study, 501 individuals aged 35 to 75 years were recruited from five health centers by random sampling stratified by age and sex (55.90 ± 14.24 years, 49.70% men). HVA was determined in two steps. Step 1: Subjects with vascular damage to the carotid arteries or peripheral arterial disease were classified as non-HVA. Step 2: The study population was classified by age and sex using the percentiles of the vascular aging index (VAI), with VAI ≤p25 considered HVA and >p25 considered non-HVA. The VAI was estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76. Carotid-femoral pulse wave velocity (cfPWV) was measured with the SphygmoCor ® device, and carotid intima-media thickness using Sonosite Micromax ® ultrasound. Mediterranean diet (MD) adherence, alcohol and tobacco use were recorded through validated questionnaires. Physical activity was assessed with the ActiGraph-GT3X ® accelerometer., Results: The mean VAI value was 61.23 ± 12.86 (men-63.47 ± 13.75 and women-59.04 ± 11.54; p < 0.001). HVA was found in 18.9% (men-19.9% and women-17.8%). In the multiple regression analysis after adjusting for possible confounding factors, the mean VAI value showed a positive association with alcohol use (β = 0.020) and sedentary hours per week (β = 0.109) and a negative association with hours of activity per week (β = -0.102) and with the number of healthy lifestyles (β = -0.640). In the logistic regression analysis, after adjusting for possible confounding factors and compared to those classified as non-HVA, subjects classified as HVA were more likely to show MD adherence (OR = 0.571), do more than 26 h per week of physical activity (OR = 1.735), spend under 142 h per week being sedentary (OR = 1.696), and have more than two healthy lifestyles (OR = 1.877)., Conclusion: The results of this study suggest that the more time spent doing physical activity and the less time spent in a sedentary state, the lower the vascular aging index and the greater the likelihood of being classified in the group of subjects with HVA.

The main objective of this work is to investigate the relationship between the Mediterranean diet (MD) and metabolic syndrome (MetS) and its components in Caucasian subjects between 35 and 74 years. The secondary objective is to analyze sex differences., Methods: A cross-sectional trial. This study utilized data from the EVA, MARK, and EVIDENT studies, and a total of 3417 subjects with a mean age ± SD of 60.14 ± 9.14 years (57% men) were included. We followed the five criteria established in the National Cholesterol Education Program III to define MetS. The MD was assessed with the 14-item Mediterranean diet adherence screener (MEDAS) used in the PREDIMED study. Good adherence was considered when the MD value was higher than the median value., Results: The mean ± SD value of the MEDAS questionnaire was 5.83 ± 2.04 (men 5.66 ± 2.06 and women 6.04 ± 1.99; p < 0.001). Adherence to the MD was observed by 38.6% (34.3% men and 40.3% women; p < 0.001). MetS was observed in 41.6% (39.0% men and 45.2% women; p < 0.001). In the multiple regression analysis, after adjusting for possible confounders, the mean MD value showed a negative association with the number of MetS components per subject (β = -0.336), and with the different components of MetS: systolic blood pressure (β = -0.011), diastolic blood pressure (β = -0.029), glycemia (β = -0.009), triglycerides (β = -0.004), and waist circumference (β = -0.026), except with the HDL-cholesterol value which showed a positive association (β = 0.021); p < 0.001 in all cases. In the logistic regression analysis performed, we found that an increase in MD adherence was associated with a decrease in the probability of MetS (OR = 0.56) and its components: blood pressure levels ≥ 130/85 mmHg (OR = 0.63), fasting plasma glucose ≥ 100 mg/dL (OR = 0.62), triglyceride levels ≥ 150 mg/dL (OR = 0.65), waist circumference levels ≥ 88 cm in women and ≥102 cm in men (OR = 0.74), and increased high-density lipoprotein cholesterol < 40 mg/dL in men and <50 mg/dL in women (OR = 1.70); p < 0.001 in all cases. The results by sex were similar, both in multiple regression and logistic regression., Conclusions: The results found in our work indicate that the greater the adherence to the MD, the lower the probability of presenting MetS. This result is repeated in the study by sex. More studies are needed to clarify that these results can be extended to the rest of the Mediterranean countries, and to other countries outside the Mediterranean basin.

Background: Behavioral and substance addictions are prevalent health problems that, alongside obesity, are linked to reduced physical activity and increased sedentary time. Similarly, arterial stiffness and vascular aging are processes that begin gradually at an early age and are closely associated with morbidity and mortality from cardiovascular diseases. The main objective of this study is to analyze how addictions are related to obesity and body fat distribution, physical activity, sedentary time, arterial stiffness and vascular aging, as well as sleep quality, cognitive function and gender differences in young adults aged between 18 and 34 years., Methods: This cross-sectional descriptive observational study will analyze data from 500 subjects (250 men and 250 women) aged 18-34 without cardiovascular disease, selected by simple random sampling with replacement from the urban population of the city center of Salamanca (34,044 people aged 18-34, with 18,450 women and 15,594 men). Behavioral and substance addictions, as well as sleep quality and cognitive impairment will be assessed using questionnaires. The Pittisburg Sleep Quality Index (PSQI) will be used to measure sleep quality and the Ford questionnaire will be used to measure insomnia in response to stress. For obesity, weight, height, waist and hip circumference, body composition will be measured with the Inbody 230 ® impedance meter. For physical activity and sedentary time, we will use the Actigraph ® accelerometer alongside the international physical activity questionnaire (IPAQ) and the Marshall questionnaire. The Sphygmocor System ® will be used for pulse wave analysis and carotid-femoral pulse wave velocity (cfPWV), while the Vasera VS-2000 ® will measure cardio ankle vascular index (CAVI) and brachial-ankle pulse wave velocity (baPWV). Vascular aging will be calculated with the 10th and 90th percentiles of cfPWV or baPWV. Demographic, analytical variables will be collected, as will data to assess vascular, cardiac, renal, and brain injury., Discussion: Addictions are on the rise in today's society, affecting the mental health and well-being of those who suffer from them, generating important social problems such as job loss, family dysfunction, debt and social isolation. Together with obesity, they are prevalent health problems in young adults and are associated with lower physical activity and higher sedentary time. Meanwhile, arterial stiffness and vascular aging are processes that begin gradually at an early age and determine morbidity and mortality caused by cardiovascular diseases. The results of this project will allow us to understand the situation regarding behavioral and substance addictions in young adults. Better understanding of these addictions will in turn facilitate the development of more effective prevention strategies and intervention programs, which can then reduce the negative impact at both the individual and societal levels., Clinical Trial Registration: [ClinicalTrials.gov], identifier [NCT05819840]., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Vicente-Gabriel, Lugones-Sánchez, Tamayo-Morales, Vicente Prieto, González-Sánchez, Conde Martín, Gómez-Sánchez, Rodríguez-Sánchez, García-Ortiz, Gómez-Sánchez, Gómez-Marcos and EVA-Adic Investigators Group.)

Introduction: Personalized programs of integrated strength and balance activities have been shown their effectiveness in falls reduction in the older adults., Objective: To measure whether a group intervention with the strength and balance principles of the sLiFE program is more effective than standard health advice in reducing the incidence of falls., Methods: The study will comprise 650 participants with more than 65 years who live at home, observing established inclusion and exclusion criteria. Participants will be randomly assigned in two groups: group intervention ( n  = 325) and standard health advice ( n  = 325). The intervention group will follow the balance and strength activities described in the LiFE program manual. The group intervention will be carried out in groups of 12-14 and will consist of seven one-hour sessions over 12 weeks in health centres. Incidence of falls and quality of life will be assessed as primary outcome variables. Fear of falling and exercise adherence will be analysed as secondary outcome variables., Discussion: Physical activity has been put forward as an effective treatment technique for these patients; however, long-term adherence to these programs remains a challenge. Group interventions could reduce dropout rates., Conclusion: Falls represent a major health problem globally due to the disability they cause in older people. Prevention would help reduce not only their incidence but also the health costs derived from their treatment. Group intervention helps clinicians to save resources and time, being able to attend more people with the same quality of care., Clinical Trial Registration: https://clinicaltrials.gov/study/NCT05912088?distance=50&term=NCT05912088&rank=1, identifier NCT05912088., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Llamas-Ramos, Llamas-Ramos, Lugones-Sánchez, González-García, Tamayo-Morales, Alvarado-Omenat, Pablos-Hernández, Gómez-Marcos, García-Ortiz and Rodríguez-Sánchez.)

Background: Currently, vaccination of livestock with attenuated strains of Brucella remains an essential measure for controlling brucellosis, although these vaccines may be dangerous to humans. The aim of this study was to review the risk posed to humans by occupational exposure to vaccine strains and the measures that should be implemented to minimize this risk., Methods: This article reviewed the scientific literature indexed in PubMed up to September 30, 2023, following "the PRISMA guidelines". Special emphasis was placed on the vaccine strain used and the route of exposure. Non-occupational exposure to vaccine strains, intentional human inoculation, publications on exposure to wild strains, and secondary scientific sources were excluded from the study., Results: Nineteen primary reports were found and classified in three subgroups: safety accidents in vaccine factories that led to an outbreak (n = 2), survellaince studies on vaccine manufacturing workers with a serologic diagnosis of Brucella infection (n = 3), and publications of infection by vaccine strains during their administration, including case reports, records of occupational accidents and investigations of outbreaks in vaccination campaigns (n = 14). Although accidental exposure during vaccine manufacturing were uncommon, they could provoke large outbreaks through airborne spread with risk of spread to the neighboring population. Besides, despite strict protection measures, a percentage of vaccine manufacturing workers developed positive Brucella serology without clinical infection. The most frequent type of exposure with symptomatic infection was needle injury during vaccine administration. Prolonged contact with the pathogen, lack of information and a low adherence to personal protective equipment (PPE) use in the work environment were commonly associated with infection., Conclusions: Brucella vaccines pose occupational risk of contagion to humans from their production to their administration to livestock, although morbidity is low and deaths were not reported. Recommended protective measures and active surveillance of exposed workers appeared to reduce this risk. It would be advisable to carry out observational studies and/or systematic registries using solid diagnostic criteria., Competing Interests: All authors declare that not competing interests exists., (Copyright: © 2024 Vives-Soto et al.

Introduction: The increasing aging of the population brings with it an increase in the incidence of neurocognitive disorder (NCD) as well as various situations that generate dependence., Objective: To analyze by means of a systematic review the relationship between NCD and dependence with the risk of mortality in the elderly., Methods: A bibliographic search of longitudinal studies published in Pubmed and Scopus addressing the relationship between NCI, dependence for basic activities of daily living (ADL) and mortality published between 1995 and 2021 was performed. Of the 1040 articles found, 10 studies were selected., Results: It was observed that cohorts of elderly people with NCI presented mortality risk associated with ABVD impairment (Barthel test) and Mini-Mental State Examination scores following a significant linear trend. Other factors associated with mortality risk were low levels of education, living alone, and frailty., Conclusions: The results underline the importance of performing assessments of cognitive and functional status using validated scales, since both areas are associated with mortality. The link between the three terms used in the search for this work is clear, but it is noteworthy that there are few longitudinal studies that analyze them together. The assessment of dependence and cognitive function in older adults should be considered in both research and clinical practice as it would provide information on their possible relationship with mortality., (Copyright © 2023 SEGG.

Heart and kidney have a closely interrelated pathophysiology. Acute kidney injury (AKI) is associated with significantly increased rates of cardiovascular events, a relationship defined as cardiorenal syndrome type 3 (CRS3). The underlying mechanisms that trigger heart disease remain, however, unknown, particularly concerning the clinical impact of AKI on cardiac outcomes and overall mortality. Tumour necrosis factor-like weak inducer of apoptosis (TWEAK) and its receptor fibroblast growth factor-inducible 14 (Fn14) are independently involved in the pathogenesis of both heart and kidney failure, and recent studies have proposed TWEAK as a possible therapeutic target; however, its specific role in cardiac damage associated with CRS3 remains to be clarified. Firstly, we demonstrated in a retrospective longitudinal clinical study that soluble TWEAK plasma levels were a predictive biomarker of mortality in patients with AKI. Furthermore, the exogenous application of TWEAK to native ventricular cardiomyocytes induced relevant calcium (Ca 2+ ) handling alterations. Next, we investigated the role of the TWEAK-Fn14 axis in cardiomyocyte function following renal ischaemia-reperfusion (I/R) injury in mice. We observed that TWEAK-Fn14 signalling was activated in the hearts of AKI mice. Mice also showed significantly altered intra-cardiomyocyte Ca 2+ handling and arrhythmogenic Ca 2+ events through an impairment in sarcoplasmic reticulum Ca 2+ -adenosine triphosphatase 2a pump (SERCA 2a ) and ryanodine receptor (RyR 2 ) function. Administration of anti-TWEAK antibody after reperfusion significantly improved alterations in Ca 2+ cycling and arrhythmogenic events and prevented SERCA 2a and RyR 2 modifications. In conclusion, this study establishes the relevance of the TWEAK-Fn14 pathway in cardiac dysfunction linked to CRS3, both as a predictor of mortality in patients with AKI and as a Ca 2+ mishandling inducer in cardiomyocytes, and highlights the cardioprotective benefits of TWEAK targeting in CRS3. © 2023 The Authors.

Background: In this study we analyzed the association between physical activity and sedentary lifestyle with vascular aging in Spanish populations aged 35-75 years., Methods: A cross-sectional study was developed, in which 501 subjects aged 35-75 years were recruited. Physical activity and sedentary time were measured with an accelerometer (Actigraph GTX3) for a week. We measured carotid-femoral pulse wave velocity (cfPWV) by a Sphygmo Cor® device and carotid intima-media thickness (cIMT) by ultrasound (Sonosite Micromax®). The vascular aging index (VAI) was calculated as described in the literature. Vascular aging was defined considering the 25th and 75th percentiles by age and sex of cfPWV and VAI, presence of vascular injury, type-2 diabetes mellitus or arterial hypertension. Individuals were classified into three groups: healthy, normal, and early vascular aging., Results: The mean age of the sample was 55.90 ± 14.24 years, 50% being women. Total physical activity was negatively associated with cfPWV ( β = -0.454) and VAI ( β = -1.845). Similarly, the number of steps per day obtained a negative association with cfPWV ( β = -0.052) and VAI ( β = -0.216), while sedentary time showed a positive association with cfPWV ( β = 0.028) and VAI ( β = 0.117). In the analysis by sex, the results showed similar values. The odds ratio (OR) of total physical activity of subjects classified as early vascular aging (EVA) with regarding those classified as healthy vascular aging (HVA) was 0.521 (95% confidence interval [CI] 0.317 to 0.856) for cfPWV, and 0.565 (95% CI 0.324 to 0.986) for VAI. In terms of the number of steps per day, the OR was 0.931 (95% CI 0.875 to 0.992) for cfPWV and 0.916 (95% CI 0.847 to 0.990) for VAI and for sedentary time the OR was 1.042 (95% CI 1.011 to 1.073) for cfPWV and 1.037 (95% CI 1.003 to 1.072) for VAI. The OR of subjects classified as vigorous physical activity was 0.196 (95% CI 0.041 to 0.941) using cfPWV and 0.161 (95% CI 0.032 to 0.820) using VAI. In the analysis by sex, the results showed an association in men when cfPWV was used and an association in women when VAI was used to define vascular aging., Conclusions: The results of this study indicate that the more time spent performing physical activity and the less sedentary time, the lower the arterial stiffness and the probability of developing early vascular aging., Clinical Trial Registration: The study was registered in ClinicalTrials.gov (number: NCT02623894)., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 The Author(s).
