Phthalate exposure and the metabolic syndrome: A systematic review and meta-analysis.

Phthalates are chemicals widely used in plastic-based consumer products, and human exposure is universal. They are classified as endocrine disruptors, and specific phthalate metabolites have been associated with an increased risk of cardiometabolic diseases. The aim of this study was to assess the association between phthalate exposure and the metabolic syndrome in the general population. A comprehensive literature search was performed in four databases (Web of Science, Medline, PubMed, and Scopus). We included all the observational studies that evaluate the association between phthalate metabolites and the metabolic syndrome available until January 31st, 2023. Pooled Odds Ratios (OR) and their 95% confidence intervals were calculated by using the inverse-variance weighted method. Nine cross-sectional studies and 25,365 participants aged from 12 to 80 were included. Comparing extreme categories of phthalate exposure, the pooled ORs for the metabolic syndrome were: 1.08 (95% CI, 1.02-1.16, I2 = 28%) for low molecular weight phthalates, and 1.11 (95% CI, 1.07-1.16, I2 = 7%) for high molecular weight phthalates. For individual phthalate metabolites, the pooled ORs that achieved statistical significance were: 1.13 (95% CI, 1.00-1.27, I2 = 24%) for MiBP; 1.89 (95% CI, 1.17-3.07, I2 = 15%) for MMP in men; 1.12 (95% CI, 1.00-1.25, I2 = 22%) for MCOP; 1.09 (95% CI, 0.99-1.20, I2 = 0%) for MCPP; 1.16 (95% CI, 1.05-1.28, I2 = 6%) for MBzP; and 1.16 (95% CI, 1.09-1.24, I2 = 14%) for DEHP (including ΣDEHP and its metabolites). In conclusion, both low molecular weight and high molecular weight phthalates were associated with an 8 and 11% higher prevalence of the MetS, respectively. The exposure to six specific phthalate metabolites was associated with a higher prevalence of the MetS.

Association of single and joint metals with albuminuria and estimated glomerular filtration longitudinal change in middle-aged adults from Spain: The Aragon workers health study.

The nephrotoxicity of low-chronic metal exposures is unclear, especially considering several metals simultaneously. We assessed the individual and joint association of metals with longitudinal change in renal endpoints in Aragon Workers Health Study participants with available measures of essential (cobalt [Co], copper [Cu], molybdenum [Mo] and zinc [Zn]) and non-essential (As, barium [Ba], Cd, chromium [Cr], antimony [Sb], titanium [Ti], uranium [U], vanadium [V] and tungsten [W]) urine metals and albumin-to-creatinine ratio (ACR) (N = 707) and estimated glomerular filtration rate (eGFR) (N = 1493) change. Median levels were 0.24, 7.0, 18.6, 295, 3.1, 1.9, 0.28, 1.16, 9.7, 0.66, 0.22 µg/g for Co, Cu, Mo, Zn, As, Ba, Cd, Cr, Sb, Ti, V and W, respectively, and 52.5 and 27.2 ng/g for Sb and U, respectively. In single metal analysis, higher As, Cr and W concentrations were associated with increasing ACR annual change. Higher Zn, As and Cr concentrations were associated with decreasing eGFR annual change. The shape of the longitudinal dose-responses, however, was compatible with a nephrotoxic role for all metals, both in ACR and eGFR models. In joint metal analysis, both higher mixtures of Cu-Zn-As-Ba-Ti-U-V-W and Co-Cd-Cr-Sb-V-W showed associations with increasing ACR and decreasing eGFR annual change. As and Cr were main drivers of the ACR change joint metal association. For the eGFR change joint metal association, while Zn and Cr were main drivers, other metals also contributed substantially. We identified potential interactions for As, Zn and W by other metals with ACR change, but not with eGFR change. Our findings support that Zn, As, Cr and W and suggestively other metals, are nephrotoxic at relatively low exposure levels. Metal exposure reduction and mitigation interventions may improve prevention and decrease the burden of renal disease in the population.

Arsenic exposure and human blood DNA methylation and hydroxymethylation profiles in two diverse populations from Bangladesh and Spain.

BACKGROUND: Associations of arsenic (As) with the sum of 5-mC and 5-hmC levels have been reported; however, As exposure-related differences of the separated 5-mC and 5-hmC markers have rarely been studied. METHODS: In this study, we evaluated the association of arsenic exposure biomarkers and 5-mC and 5-hmC in 30 healthy men (43-55 years) from the Aragon Workers Health Study (AWHS) (Spain) and 31 healthy men (31-50 years) from the Folic Acid and Creatinine Trial (FACT) (Bangladesh). We conducted 5-mC and 5-hmC profiling using Infinium MethylationEPIC arrays, on paired standard and modified (ox-BS in AWHS and TAB in FACT) bisulfite converted blood DNA samples. RESULTS: The median for the sum of urine inorganic and methylated As species (ΣAs) (µg/L) was 12.5 for AWHS and 89.6 for FACT. The median of blood As (µg/L) was 8.8 for AWHS and 10.2 for FACT. At a statistical significance p-value cut-off of 0.01, the differentially methylated (DMP) and hydroxymethylated (DHP) positions were mostly located in different genomic sites. Several DMPs and DHPs were consistently found in AWHS and FACT both for urine ΣAs and blood models, being of special interest those attributed to the DIP2C gene. Three DMPs (annotated to CLEC12A) for AWHS and one DHP (annotated to NPLOC4) for FACT remained statistically significant after false discovery rate (FDR) correction. Pathways related to chronic diseases including cardiovascular, cancer and neurological were enriched. CONCLUSIONS: While we identified common 5-hmC and 5-mC signatures in two populations exposed to varying levels of inorganic As, differences in As-related epigenetic sites across the study populations may additionally reflect low and high As-specific associations. This work contributes a deeper understanding of potential epigenetic dysregulations of As. However, further research is needed to confirm biological consequences associated with DIP2C epigenetic regulation and to investigate the role of 5-hmC and 5-mC separately in As-induced health disorders at different exposure levels.

Analysis of the impact of social determinants and primary care morbidity on population health outcomes by combining big data: A research protocol.

Background: In recent years, different tools have been developed to facilitate analysis of social determinants of health (SDH) and apply this to health policy. The possibility of generating predictive models of health outcomes which combine a wide range of socioeconomic indicators with health problems is an approach that is receiving increasing attention. Our objectives are twofold: (1) to predict population health outcomes measured as hospital morbidity, taking primary care (PC) morbidity adjusted for SDH as predictors; and (2) to analyze the geographic variability of the impact of SDH-adjusted PC morbidity on hospital morbidity, by combining data sourced from electronic health records and selected operations of the National Statistics Institute (Instituto Nacional de Estadística/INE). Methods: The following will be conducted: a qualitative study to select socio-health indicators using RAND methodology in accordance with SDH frameworks, based on indicators published by the INE in selected operations; and a quantitative study combining two large databases drawn from different Spain's Autonomous Regions (ARs) to enable hospital morbidity to be ascertained, i.e., PC electronic health records and the minimum basic data set (MBDS) for hospital discharges. These will be linked to socioeconomic indicators, previously selected by geographic unit. The outcome variable will be hospital morbidity, and the independent variables will be age, sex, PC morbidity, geographic unit, and socioeconomic indicators. Analysis: To achieve the first objective, predictive models will be used, with a test-and-training technique, fitting multiple logistic regression models. In the analysis of geographic variability, penalized mixed models will be used, with geographic units considered as random effects and independent predictors as fixed effects. Discussion: This study seeks to show the relationship between SDH and population health, and the geographic differences determined by such determinants. The main limitations are posed by the collection of data for healthcare as opposed to research purposes, and the time lag between collection and publication of data, sampling errors and missing data in registries and surveys. The main strength lies in the project's multidisciplinary nature (family medicine, pediatrics, public health, nursing, psychology, engineering, geography).

Work Shift, Lifestyle Factors, and Subclinical Atherosclerosis in Spanish Male Workers: A Mediation Analysis.

(1) Background: Working night shifts has been associated with altered circadian rhythms, lifestyle habits, and cardiometabolic risks. No information on the potential association of working shift and the presence of atherosclerosis is available. The aim of this study was to quantify the association between different work shifts and the presence of subclinical atherosclerosis objectively measured by imaging. (2) Methods: Analyses were conducted on the baseline data of the Aragon Workers Health Study (AWHS) cohort, including information on 2459 middle-aged men. Categories of shift work included central day shift, rotating morning-evening or morning-evening-night shift, and night shift. The presence of atherosclerotic plaques was assessed by 2D ultrasound in the carotid and femoral vascular territories. Multivariable logistic models and mediation analysis were conducted to characterize and quantify the association between study variables. (3) Results: Participants working night or rotating shifts presented an overall worse cardiometabolic risk profile, as well as more detrimental lifestyle habits. Workers in the most intense (morning-evening-night) rotating shift presented higher odds of subclinical atherosclerosis (odds ratio: 1.6; 95% confidence interval: 1.12 to 2.27) compared to workers in the central shift, independently of the presence of lifestyle and metabolic risk factors. A considerable (21%) proportion of this association was found to be mediated by smoking, indicating that altered sleep-wake cycles have a direct relationship with the early presence of atherosclerotic lesions. (4) Conclusions: Work shifts should be factored in during workers health examinations, and when developing effective workplace wellness programs.

The additive effect of adherence to multiple healthy lifestyles on subclinical atherosclerosis: Insights from the AWHS.

BACKGROUND: Public health strategies targeting multiple healthy behaviors, rather than individual factors, have been proposed as more efficient strategies to promote cardiovascular health. However, the additive effect of multiple targets on primary prevention has not been fully characterized. OBJECTIVE: To examine how adherence to multiple healthy behaviors is associated with the presence of subclinical atherosclerosis, a measure of early cardiovascular disease. METHODS: Analysis of a baseline data from 1798 middle-aged men from the Aragon Workers Health Study conducted between 2009 and 2010. Healthy behaviors were defined according to American Heart Association recommendations, aligned with Spanish Nutritional recommendations and included moderate alcohol consumption, smoking abstinence, no abdominal adiposity, decreased sedentarism, and adherence to Alternate Mediterranean Dietary Index. Presence of coronary artery calcium and plaques in femoral and carotid was quantified by a 16-slice computed tomography scanner and 2D ultrasound. RESULTS: Moderate alcohol consumption, as well as adherence to Mediterranean diet is independently associated with a 6% lower risk of having subclinical atherosclerosis. Smoking abstinence is associated with a 11% lower risk of subclinical atherosclerosis. Those who follow 3 lifestyle behaviors (Mediterranean diet, nonsmoking, and moderate alcohol intake) have 18% lower odds of presenting subclinical atherosclerosis compared with those who do not follow these protective lifestyle habits. CONCLUSION: Adoption of multiple healthy lifestyle behaviors early in life could be a key strategy to tackle the onset of atherosclerosis and reduce cardiovascular disease burden.

Risk factors control for primary prevention of cardiovascular disease in men: Evidence from the Aragon Workers Health Study (AWHS).

Benefits of cardiovascular disease (CVD) risk factors control are well known, but goals achievement remains low. The objective of this study is to evaluate the prevalence of CVD risk factors among men ina worker's cohort with no previous CVD, to study control variations across time and the factors associated with poor control. To this end, we conducted a cohort reexamination (2010-2014) within the context of the Aragon Workers Health Study (AWHS). Data from working characteristics, analytical values and pharmacological prescription were included in the analysis. Prevalences of risk factor diagnosis and control were calculated, as well as factors associated with poor control. The prevalence of CVD risk factors was high. In 2014dyslipidaemia was the most prevalent (85.2%) followed by Hypertension (HT) (42.0%). People under treatment increased for the period analysed (p<0.001). The proportion of people treated varied from 72.2% in Diabetes Mellitus to 31.1% in dyslipidaemia in 2014. 46.2% of the workers with HT were controlled, decreasing to 21.9% in Diabetes and 11.0% in dyslipidaemia (2014). Working in a turn different to central shift was associated with poor control, especially for those working at night with HT (Odds Ratio in 2010: 3.6; Confidence Interval 95% 1.8-7.4) and dyslipidaemia (Odds Ratio 2010: 4.7; Confidence Interval 95% 1.3-16.4). We conclude that, although CVD control has increased significantly for the period studied, there are still many people that do not receive any treatment, and control goals are normally not achieved.

Influence of cardiovascular condition on retinal and retinal nerve fiber layer measurements.

OBJECTIVE: To assess changes in the retinal nerve fiber layer (RNFL) and macula in subjects with cardiovascular risk factors or subclinical ischemia. DESIGN: Prospective and observational study. METHODS: A total of 152 healthy men underwent cardiovascular examination, including quantification of subclinical atheroma plaques by artery ultrasound scans, blood analysis, and a complete ophthalmic evaluation, including spectral-domain optical coherence tomography. The variables registered in cardiovascular examination were quantification of classic major risk factors, subclinical atheroma plaques by artery ultrasound scans, and analytical records. The ophthalmic evaluation registered RNFL and macular thickness. RESULTS: Mean subject age was 51.27±3.71 years. The 40 subjects without classic cardiovascular risk factors did not show differences in RNFL and macular thicknesses compared with the 112 subjects with at least one risk factor (except in sector 9 that showed higher thicknesses in subjects with ≥1 risk factor). Comparison between the group of subjects with and without atheroma plaques revealed no differences in RNFL and macular thicknesses. The sub-analysis of subjects with subclinical atheroma plaques in the common carotid artery revealed a significant reduction in central macular thickness in the left eye compared with the right eye (p = 0.016), RNFL in the superior quadrant (p = 0.007), and the 11 o'clock sector (p = 0.020). Comparison between smokers and nonsmokers revealed that smokers had significant thinning of the central macular thickness (p = 0.034), the nasal RNFL quadrant (p = 0.006), and the 3 and 5 o'clock sectors (p = 0.016 and 0.009). CONCLUSIONS: Classic cardiovascular risk factors do not cause RNFL or macular thickness reduction, but tobacco smoking habit reduces nasal RNFL thickness. Subclinical atherosclerosis in the common carotid artery associates a reduction in central macular and nasal RNFL quadrant thicknesses in the left eye compared with the right eye.

Adherence to a Mediterranean diet is associated with the presence and extension of atherosclerotic plaques in middle-aged asymptomatic adults: The Aragon Workers' Health Study.

BACKGROUND: The Mediterranean diet (MeDi) is known to prevent cardiovascular events but the mechanisms mediating this association are not fully understood. OBJECTIVE: The objective of the study was to examine the association between MeDi adherence and the presence and extent of atherosclerotic plaques in carotid, femoral, and aorta territories and its relationship with risk factors in asymptomatic middle-aged adults. METHODS: Cross-sectional analysis of the Aragon Workers' Health Study, a cohort of 2588 subjects (94.9% men aged 51.3 ± 3.89 years) without previous cardiovascular history. Participants underwent carotid, femoral, and aorta ultrasound for the quantification of number and thickness of plaques and intima-media thickness. To estimate the participant's adherence to MeDi, we computed the Alternative MEDiterranean index (aMED). RESULTS: The overall aMED score was 4.19 ± 1.70, representing a moderate adherence to MeDi. aMED score was associated with the presence of plaque in femoral arteries (odds ratio highest vs lowest aMED score quartile: 0.63; 95% confidence interval: 0.48-0.83; P trend = .045) independently of risk factors and mediators. The strongest association between aMED quartiles and presence of plaque was found among smokers, both in femoral (0.39 [0.22-0.69]; P trend = .001) and in any territory (0.33 [0.14-0.79], P trend = .008). aMED was inversely associated with the number of plaques in all territories except for carotids. CONCLUSION: MeDi adherence showed a dose-dependent protective association with the presence, number, and thickness of plaques independent of other risk factors. The association was strongest for femoral arteries and among smokers.

Identification of differentially methylated BRCA1 and CRISP2 DNA regions as blood surrogate markers for cardiovascular disease.

Genome-wide Illumina InfiniumMethylation 450 K DNA methylation analysis was performed on blood samples from clinical atherosclerosis patients (n = 8) and healthy donors (n = 8) in the LVAD study (NCT02174133, NCT01799005). Multiple differentially methylated regions (DMR) could be identified in atherosclerosis patients, related to epigenetic control of cell adhesion, chemotaxis, cytoskeletal reorganisations, cell proliferation, cell death, estrogen receptor pathways and phagocytic immune responses. Furthermore, a subset of 34 DMRs related to impaired oxidative stress, DNA repair, and inflammatory pathways could be replicated in an independent cohort study of donor-matched healthy and atherosclerotic human aorta tissue (n = 15) and human carotid plaque samples (n = 19). Upon integrated network analysis, BRCA1 and CRISP2 DMRs were identified as most central disease-associated DNA methylation biomarkers. Differentially methylated BRCA1 and CRISP2 regions were verified by MassARRAY Epityper and pyrosequencing assays and could be further replicated in blood, aorta tissue and carotid plaque material of atherosclerosis patients. Moreover, methylation changes at BRCA1 and CRISP2 specific CpG sites were consistently associated with subclinical atherosclerosis measures (coronary calcium score and carotid intima media thickness) in an independent sample cohort of middle-aged men with subclinical cardiovascular disease in the Aragon Workers' Health Study (n = 24). Altogether, BRCA1 and CRISP2 DMRs hold promise as novel blood surrogate markers for early risk stratification and CVD prevention.

Apolipoprotein E4 association with metabolic syndrome depends on body fatness.

BACKGROUND AND AIMS: The human Apolipoprotein E (APOE) gene is polymorphic. The APOE*4 allele is a risk factor for cardiovascular disease and could contribute to the development of the metabolic syndrome (MetS) as it may affect all MetS components. We hypothesize that the common APOE4 polymorphism differentially regulates MetS risk and that this association might be modulated by body fatness. METHODS & RESULTS: We used body mass index (BMI) as surrogate of fatness and cross-sectionally studied the prevalence of MetS in 4408 middle-aged men of the Aragon Workers Health Study (AWHS). Our analysis revealed i) a gene dose-dependent association between APOE*4 allele and increased risk for MetS, ii) this association primarily derived from the overweight subjects. For these individuals, the MetS risk was higher in APOE*4 carriers than in non-carriers (Odds Ratio = 1.31; 95% CI, 1.03-1.67). Additionally, we examined 3908 healthy young individuals from the Coronary Artery Risk Development in Young Adults (CARDIA) cohort, followed-up for 25 years. Compared with APOE*4 non-carriers, APOE*4 presence significantly increased the risk of developing MetS (Hazard Ratio, 1.12; 95% CI, 1.00-1.26). Again, an interplay between APOE*4 and the longitudinal development of fatness towards the onset of MetS occurred throughout the study. For individuals with BMI gain below the median, the cumulative onset rate of MetS was significantly higher in APOE*4 carriers than in the non-carriers (HR, 1.29; 95% CI, 1.07-1.55). CONCLUSIONS: Carrying APOE*4 alleles increases MetS in a dose-dependent manner, characterizing individual's APOE genotype might help identify at-risk subjects for preventive intervention.

[Compliance with Physical Activity Recommendations and Associated Factors in a Cohort of Spanish Adult Workers]. / Factores asociados al cumplimiento de las recomendaciones sobre actividad física en población trabajadora de entre 40 y 55 años de edad.

BACKGROUND: Physical inactivity remains a public health problem worldwide. The purpose of this study was to determine compliance with physical activity (PA) recommendations developed by the World Health Organization (WHO) and to analyze the association with different cardiovascular risk factors (CVRF) and sociodemographic and lifestyle determinants in a sample of Spanish workers. METHODS: A cross sectional analysis was carried out in a sample of 2.651 individuals (2.428 men and 133 women, aged 40-55 years old) from the Aragon Workers' Health Study (AWHS). Sample was divided into two groups depending on whether they met PA recommendations during the last year, including transportation, leisure and occupational PA. Sociodemographic, anthropometric, clinical, pharmacological and lifestyle data were collected during the years 2011-2014. Median and interquartile range for quantitative variables and frequency distribution for categorical variables were used. Crude and adjusted binary logistic regression models were carried out to study the likelihood of meeting with PA recommendations based on the number of CVRF (hypertension, dyslipidemia, diabetes, obesity and smoking) present. RESULTS: 47.0% of workers complied with WHO recommendations for PA. Lower prevalence of compliance was found among those participants presenting some CVRF (39.7% in hypertensive, 38.7% in dyslipidemic and 32.7% in diabetic). Of the total study sample, 51.3% reported not performing PA or practice a light PA, 20.2% moderate and 28.5% vigorous or very vigorous PA. The likelihood of compliance with PA recommendations decreased with increasing the number of CVRF: 1 CVRF (OR: 0.62; 95%IC: 0.49-0.78), 2 CVRF (OR: 0.49; 95% IC: 0.38-0.62), 3 CVRF (OR: 0.34; 95% IC: 0.25-0.46), 4 CVRF (OR: 0.19; 95% IC: 0.11-0.32). CONCLUSIONS: Compliance with recommendations of PA in our population remains insufficient, moreover in those with increased cardiovascular risk.

ASSOCIATION BETWEEN DAILY SITTING TIME AND PREVALENT METABOLIC SYNDROME IN AN ADULT WORKING POPULATION: THE AWHS COHORT.

OBJECTIVE: the aim of this analysis was to measure the association between daily sitting time and prevalent metabolic syndrome, independently of the physical activity performed. SUBJECTS AND METHODS: the Aragon Workers' Health Study cohort consists of 5 865 participants from which a sample of 1 415 male participants (40-55 years old) with completed data at baseline was selected. Sitting time and physical activity were assessed by validated questionnaires, and the socio-demographic, clinical and biochemical covariates needed to diagnose metabolic syndrome were collected as part of the study protocols. Metabolic syndrome was defined according to the modified National Cholesterol Education Program - Adult Treatment Panel III. Multiple linear and logistic regression models were carried out to quantify this association using sitting time categorized into tertiles. RESULTS: mean sitting time was 5.78 ± 1.72 h/day, and the prevalence of metabolic syndrome was 19.2%. Comparing participants in the highest (> 6.57 h/day) versus lowest (1.85-4.57 h/day) tertile of sitting time, a positive association was observed for metabolic syndrome (OR 1.77, 95%CI: 1.25-2.49) and triglyceride (OR 1.70, 95%CI: 1.30-2.24), HDL-cholesterol (OR 1.65, 95%CI: 1.06-2.58), waist circumference (OR 1.57, 95%CI: 1.17-2.11) and fasting blood glucose (OR 1.35, 95%CI: 1.03-1.77) criteria, adjusting the level of physical activity. CONCLUSIONS: higher sitting time is associated with an increased prevalence of metabolic syndrome independently of physical activity performed. These results could be useful to carry out effective strategies for cardiovascular health promotion especially in workplaces.

Conclusiones: un mayor tiempo sentado se asocia con un aumento de la prevalencia de síndrome metabólico independientemente de la actividad física realizada. Estos resultados podrían ser útiles para llevar a cabo estrategias efectivas de promoción de la salud cardiovascular, especialmente en los lugares de trabajo.

Factores asociados al cumplimiento de las recomendaciones sobre actividad física en población trabajadora de entre 40 y 5 años de edad / Compliance with physical activity recommendations and associated factors in a cohort of spanish adult workers

Fundamentos: la inactividad física continúa siendo un problema de salud pública a nivel mundial. El objetivo del presente estudio fue determinar la adherencia a las recomendaciones de actividad física (AF) establecidas por la Organización Mundial de la Salud (OMS) de una muestra de trabajadores españoles, así como analizar su asociación con diferentes factores de riesgo cardiovascular (FRCV), indicadores sociodemográficos y de estilo de vida. Métodos: estudio tranversal con 2.651 participantes en la cohorte del Aragon Workers’ Health Study (AWHS) (2.428 varones y 133 mujeres), con edades comprendidas entre los 40-55 años. Se dividió a la población en dos grupos en función de si habían cumplido o no durante el último año las recomendaciones sobre AF establecidas por la OMS, teniendo en cuenta las actividades relacionadas con la ocupación, ocio y recreación y desplazamientos. Se registraron variables sociodemográficas, antropométricas, clínicas, farmacológicas y de estilo de vida entre los años 2011-2014. Se calcularon la mediana y el intervalo intercuartílico para variables cuantitativas y la distribución de frecuencias para las categóricas. Se estimó un modelo de regresión logística binaria crudo y ajustado para analizar la probabilidad de cumplir las recomendaciones de AF en función del número de FRCV (hipertensión, dislipemia, diabetes, obesidad y tabaquismo). Resultados: el 47,0% de participantes cumplían las recomendaciones. El cumplimiento fue del 39,7% en hipertensos, del 38,7% en dislipémicos y 32,7% en diabéticos. El 51,3% reportó no realizar AF o realizar una AF ligera, el 20,2% moderada y el 28,5% vigorosa o muy vigorosa. Los resultados mostraron cómo a medida que aumentaba el número de FRCV disminuía la probabilidad de adherirse a las recomendaciones: 1 FRCV (OR: 0,62; 95%CI: 0,49-0,78), 2 FRCV (OR: 0,49; 95%CI: 0,38-0,62), 3 FRCV (OR: 0,34; 95%CI: 0,25-0,46), 4 FRCV (OR: 0,19; 95%CI: 0,11-0,32). Conclusiones: el incumplimiento de las recomendaciones de AF en nuestra población es frecuente sobre todo en personas con mayor riesgo cardiovascular (AU)

Background: physical inactivity remains a public health problem worldwide. The purpose of this study was to determine compliance with physical activity (PA) recommendations developed by the World Health Organization (WHO) and to analyze the association with different cardiovascular risk factors (CVRF) and sociodemographic and lifestyle determinants in a sample of Spanish workers. Methods: a cross sectional analysis was carried out in a sample of 2.651 individuals (2.428 men and 133 women, aged 40-55 years old) from the Aragon Workers’ Health Study (AWHS). Sample was divided into two groups depending on whether they met PA recommendations during the last year, including transportation, leisure and occupational PA. Sociodemographic, anthropometric, clinical, pharmacological and lifestyle data were collected during the years 2011-2014. Median and interquartile range for quantitative variables and frequency distribution for categorical variables were used. Crude and adjusted binary logistic regression models were carried out to study the likelihood of meeting with PA recommendations based on the number of CVRF (hypertension, dyslipidemia, diabetes, obesity and smoking) present. Results: 47.0% of workers complied with WHO recommendations for PA. Lower prevalence of compliance was found among those participants presenting some CVRF (39.7% in hypertensive, 38.7% in dyslipidemic and 32.7% in diabetic). Of the total study sample, 51.3% reported not performing PA or practice a light PA, 20.2% moderate and 28.5% vigorous or very vigorous PA. The likelihood of compliance with PA recommendations decreased with increasing the number of CVRF: 1 CVRF (OR: 0.62; 95%IC: 0.49-0.78), 2 CVRF (OR: 0.49; 95% IC: 0.38-0.62), 3 CVRF (OR: 0.34; 95% IC: 0.25-0.46), 4 CVRF (OR: 0.19; 95% IC: 0.11-0.32). Conclusions: compliance with recommendations of PA in our population remains insufficient, moreover in those with increased cardiovascular risk (AU)

La mayor adherencia a un patrón de dieta mediterránea se asocia a una mejora del perfil lipídico plasmático: la cohorte del Aragon Health Workers Study / Greater adherence to a mediterranean dietary pattern is associated with improved plasma lipid profile: the Aragon health Workers Study Cohort

Introducción y objetivos Hay un amplio reconocimiento de la importancia de una dieta saludable para la promoción de la salud cardiovascular. El objetivo de este estudio es identificar los principales patrones alimentarios en la población española y determinar su relación con los perfiles lipídicos plasmáticos. Métodos Se llevó a cabo un análisis transversal de los datos obtenidos en 1.290 participantes de la cohorte del Aragon Workers Health Study. Se utilizaron protocolos estandarizados para la obtención de datos clínicos y bioquímicos. Se evaluó la dieta a través de un cuestionario de frecuencia de alimentación, cuantificando el consumo habitual durante los 12 meses previos. Se identificaron los principales patrones de dieta mediante un análisis factorial. Se evaluó la asociación entre la adherencia a los patrones de dieta y las concentraciones plasmáticas de lípidos mediante regresión lineal y logística. Resultados Se identificaron dos patrones de dieta: un patrón de dieta mediterránea, rica en verduras, frutas, pescado, carnes blancas, frutos secos y aceite de oliva, y un patrón de dieta occidental, rico en carnes rojas, comida rápida, productos lácteos y cereales. En comparación con los participantes que se encontraban en el quintil más bajo de adherencia al patrón de dieta occidental, los que se encontraban en el quintil más alto presentaron cifras de colesterol unido a lipoproteínas de alta densidad 4,6 mg/dl menores (p < 0,001) y de apolipoproteína A1, 8 mg/dl menores (p = 0,005) y mayor riesgo de mostrar una disminución del colesterol unido a lipoproteínas de alta densidad (odds ratio = 3,19; intervalo de confianza del 95%, 1,36-7,5; p de tendencia = 0,03). Los participantes con adherencia al patrón de dieta mediterránea presentaron cifras de colesterol unido a lipoproteínas de alta densidad 3,3 mg/dl mayores (p < 0,001) y un cociente de triglicéridos/colesterol unido a lipoproteínas de alta densidad 0,43 veces inferior (p = 0,043). Conclusiones: La adherencia al patrón de dieta mediterránea se asocia a una mejora del perfil lipídico en comparación con lo que se observa con un patrón de dieta occidental, que se asoció a menor probabilidad de que los valores de colesterol unido a lipoproteínas de alta densidad fueran óptimos en esta población

Introduction and objectives: There is wide recognition of the importance of healthy eating in cardiovascular health promotion. The purpose of this study was to identify the main dietary patterns among a Spanish population, and to determine their relationship with plasma lipid profiles. Methods: A cross-sectional analysis was conducted of data from 1290 participants of the Aragon Workers Health Study cohort. Standardized protocols were used to collect clinical and biochemistry data. Diet was assessed through a food frequency questionnaire, quantifying habitual intake over the past 12 months. The main dietary patterns were identified by factor analysis. The association between adherence to dietary patterns and plasma lipid levels was assessed by linear and logistic regression. Results: Two dietary patterns were identified: a Mediterranean dietary pattern, high in vegetables, fruits, fish, white meat, nuts, and olive oil, and a Western dietary pattern, high in red meat, fast food, dairy, and cereals. Compared with the participants in the lowest quintile of adherence to the Western dietary pattern, those in the highest quintile had 4.6 mg/dL lower high-density lipoprotein cholesterol levels (P < .001), 8 mg/dL lower apolipoprotein A1 levels (P = .005) and a greater risk of having decreased high-density lipoprotein cholesterol (odds ratio = 3.19; 95% confidence interval, 1.36-7.5; P-trend = .03). Participants adhering to the Mediterranean dietary pattern had 3.3 mg/dL higher high-density lipoprotein cholesterol levels (P < .001), and a ratio of triglycerides to high-density lipoprotein cholesterol that was 0.43 times lower (P = .043). Conclusions: Adherence to the Mediterranean dietary pattern is associated with improved lipid profile compared with a Western dietary pattern, which was associated with a lower odds of optimal high-density lipoprotein cholesterol levels in this population (AU)

Soluble and insoluble dietary fibre intake and risk factors for metabolic syndrome and cardiovascular disease in middle-aged adults: the AWHS cohort / Ingesta de fibra soluble e insoluble y factores de riesgo de síndrome metabólico y enfermedad cardiovascular en adultos de mediana edad: la cohorte AWHS

Introduction: The Westernization of the Mediterranean lifestyle has led to a modification of certain dietary habits such as a decrease in the consumption of dietary fibre-rich foods. The impact of these changes on cardiovascular diseases (CVD) has been studied over the last few years and the effect of the different sources of fibre on cardiovascular risk parameters and coronary heart disease (CHD) continues to create controversy. Objective: To evaluate the association between the source of dietary fibre and the prevalence of metabolic syndrome (MetS) and other cardiovascular risk factors in a Spanish working population. Subjects and methods: The study was carried out in a sample of 1592 Spanish workers free of CVD (40-55 years old) within the Aragon Workers' Health Study (AWHS) cohort. Sociodemographic, anthropometric, clinical and biochemical data were collected. Fibre intake was assessed by means of a validated 136-items semiquantitative food-frequency questionnaire. MetS was defined by using the modified National Cholesterol Education Programme - Adult Treatment Panel III (NCEP- ATP III) definition. Results: After adjusting for possible confounding factors, we found an inverse association between insoluble fibre intake and systolic and diastolic blood pressure, total cholesterol, triglycerides, apolipoprotein B100 and ratio TG/HDL. Soluble fibre was inversely associated with triglycerides and apolipoprotein B100. Furthermore, prevalence of MetS was found to be lower (OR 0.62, 95% CI: 0.40-0.96) in those participants in the highest quartile of insoluble fibre intake. Conclusion: A higher intake of insoluble fibre could play an important role in the control and management of hypertension, lipid profile and MetS (AU)

Introducción: La occidentalización del estilo de vida mediterráneo ha dado lugar a una modificación de ciertos hábitos dietéticos, tales como una disminución en el consumo de alimentos ricos en fibra dietética. El impacto de estos cambios sobre las enfermedades cardiovasculares (ECV) se ha estudiado en los últimos años y el efecto de las diferentes fuentes de fibra en los parámetros de riesgo cardiovascular y en la enfermedad coronaria sigue creando controversia. Objetivo: Evaluar la asociación entre la fuente de fibra dietética y la prevalencia de síndrome metabólico (SM) y otros factores de riesgo cardiovascular en una población laboral española. Sujetos y métodos: El estudio se llevó a cabo en una muestra de 1592 trabajadores españoles libres de ECV (40-55 años) pertenecientes a la cohorte del Estudio de la Salud de los Trabajadores de Aragón (AWHS). Se recogieron datos sociodemográficos, antropométricos, clínicos y bioquímicos. La ingesta de fibra se evaluó por medio de un cuestionario semicuantitativo de frecuencia de consumo de alimentos de 136-items previamente validado. Para la definición de SM se siguieron los criterios del Programa Nacional de Educación del Colesterol en el marco del III Panel de Tratamiento de Adultos (NCEPATP III). Resultados: Se encontró una asociación inversa entre el consumo de fibra insoluble y la presión arterial sistólica y diastólica, colesterol total, triglicéridos, apolipoproteína B100 y la relación TG/HDL, tras ajustar por posibles factores de confusión. Así mismo, la fibra soluble se asoció inversamente con triglicéridos y apolipoproteína B100. Además, se encontró una menor prevalencia de SM (OR 0.62, IC del 95%: 0.40 a 0.96) en aquellos participantes en el cuartil más alto de consumo de fibra insoluble. Conclusión: Una mayor ingesta de fibra insoluble puede desempeñar un papel importante en el control y manejo de la hipertensión, el perfil lipídico y el SM (AU)
