Association between measurements of arterial stiffness and target organ damage in a general Spanish population.

INTRODUCTION: Little is known about the relationship between arterial stiffness and cardiovascular target organ damage (TOD) in the general population. The aim was to analyse the relationship between different measurements of arterial stiffness and TOD, in a general Spanish population without a history of cardiovascular event. MATERIALS AND METHODS: Transversal descriptive study. Through stratified random sampling, a total of 501 individuals were included. Carotid-femoral pulse wave velocity (cf-PWV) was measured using a SphygmoCor System®, the cardio-ankle vascular index (CAVI) was determined with aVasera VS-1500® and brachial-ankle pulse wave velocity (ba-PWV)was calculated through a validated equation. RESULTS: The average age was 55.84 ± 14.26.The percentage of vascular TOD, left ventricular hypertrophy (LVH) and renal TOD was higher in men (p < .001). A positive correlation was obtained between carotid intima-media thickness (c-IMT) and the measurements of vascular function. In the model 1 of the logistic regression analysis, cf-PWV was associated with vascular TOD (OR = 1.15, p = .040), ba-PWV was associated with vascular TOD (OR = 1.20, p = .010) and LVH (OR = 1.12, p = .047). CONCLUSIONS: The different measurements of arterial stiffness are highly associated with each other. Moreover, cf-PWV and ba-PWV were associated with vascular TOD, and ba-PWV with LVH, although they disappear when adjusting for cardiovascular risk factors. Key Messages There is a strong correlation between the different measurements of vascular structure and function. Carotid-femoral and brachial-ankle pulse wave velocity were positively associated with vascular target organ damage, the latter was also positively associated with left ventricular hypertrophy. This associations disappear when adjusting for cardiovascular risk factors.

Behavioural intervention to reduce disruptive behaviours in adult day care centres users: A randomizsed clinical trial (PROCENDIAS study).

AIM: This study assesses the effect of an intervention to reduce the disruptive behaviours (DB) presented by care recipient users of adult day care centres (ADCC), thereby reducing caregiver overload. While ADCC offer beneficial respite for family caregivers, the DB that many care recipients show promote resistance to attending these centres, which can be a great burden on their family caregivers. DESIGN: Randomized controlled clinical trial. METHODS: The study was carried out with 130 family caregivers of people attending seven ADCC in the municipality of Salamanca (Spain), randomly distributed into intervention and control groups. The intervention was applied across eight sessions, one per week, in groups of 8-10 people where caregivers were trained in the Antecedent-Behavior-Consequence (ABC) model of functional behaviour analysis. The primary outcome was the reduction of DB measured with the Revised Memory and Behavior Problems Checklist (RMBPC). RESULTS: An average reduction in the RMBPC of 4.34 points was obtained in the intervention group after applying the intervention (p < 0.01 (U de Mann-Whitney); Cohen d = 1.00); furthermore, differences were found in the Center for Epidemiologic Studies Depression Scale (CES-D) (U = -2.67; p = 0.008; Cohen d = 0.50) and in the Short Zarit Burden Interview (Short ZBI) (t = -4.10; p < 0.01; Cohen d = 0.98). CONCLUSION: The results obtained suggest that the implementation of this intervention could reduce both the frequency of DB occurrence and the reaction of the caregiver to their appearance. Improvement was also noted in the results regarding overload and emotional state of the family caregiver. IMPACT: To our knowledge, this is the first randomized clinical trial to show that an intervention based on the ABC model could reduce the frequency and reaction of DB of care recipients in ADCC increasing their quality of life, and improving the mental health and overload of their family caregivers.

Vascular aging and its relationship with lifestyles and other risk factors in the general Spanish population: Early Vascular Ageing Study.

OBJECTIVES: To describe the prevalence of healthy vascular aging (HVA), normal vascular aging and early vascular aging (EVA) in a sample of Spanish population without cardiovascular disease. The relationship of vascular aging with lifestyle, cardiovascular risk factors, psychological and inflammatory risk factors is also analyzed. METHODS: A total of 501 participants were recruited (49.70% men, aged 55.90 ±â€Š14.24 years) by random sampling. Vascular aging was defined in three steps: Step 1: participants with vascular damage in carotid arteries or peripheral artery disease were classified as EVA. Step 2: with the percentiles of carotid-to-femoral pulse wave velocity (cfPWV) we used three criteria, first, the 10th and 90th cfPWV percentiles of the population studied by age and sex; second, the 10th and 90th percentiles of the European population reference values and third, the 25th and 75th cfPWV percentiles of the population studied by age and sex. Step 3: participants with hypertension or type 2 diabetes mellitus included in HVA were reclassified as normal vascular aging. Arterial stiffness was assessed with cfPWV using a Sphygmocor device. Physical activity was measured with an accelerometer. Psychological factors, lifestyle and other clinical information were obtained by standard questionnaire. RESULTS: The global prevalence of HVA was 8 and 14% (men 8 and 10%, women 9 and 18%), and 22 and 18% (men 26 and 23%, women 17 and 12%) for EVA, using criteria a and b, respectively. In the logistic regression analysis, vascular aging maintains positive associations with more sedentary time [odds ratio (OR) = 2.37 and 4.51], having triglycerides above 150 mg/dl (OR = 6.55 and 4.06), abdominal obesity (OR = 2.73 and 2.90), increased uric acid (OR = 4.63 and 2.98) and insulin resistance index homeostatic model assessment (OR = 4.05 and 6.78), and a negative association with less physical activity (OR = 0.29 and 0.28) using criteria a and b, respectively. CONCLUSION: One in 10 has HVA and one in five EVA. The prevalence of EVA is higher in men. Study results suggest that preventive strategies aimed at increasing physical activity, reducing sedentary time and decreasing obesity and insulin resistance improve vascular aging.

Adherence to the Mediterranean Diet in Spanish Population and Its Relationship with Early Vascular Aging according to Sex and Age: EVA Study.

The objective of this study is to analyze the influence of adherence to the Mediterranean diet (MDA) and its components on early vascular aging (EVA) in a Spanish population sample free of cardiovascular disease and to analyze the differences by sex. METHODS: We recruited 501 individuals aged 35-75 without cardiovascular disease by random sampling (55.90 ± 14.24 years, 49.70% men). EVA was defined in two steps: Step 1: subjects with vascular damage in carotid arteries or peripheral artery disease were classified as EVA. Step 2: subjects at the percentile of the combined Vascular Aging Index (VAI) were classified; ≥ p90 was considered EVA and < p90 was considered normal vascular aging (NVA), estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76 by age and sex. Carotid-femoral pulse wave velocity (cfPWV) was measured by SphigmoCor System® and carotid intima-media thickness by Sonosite Micromax® ultrasound and classified thus: values ≥ Percentile 90 were considered EVA and those < Percentile 90 as NVA, with population percentiles analyzed. The principal result variable was assessed using the 14-item MEDAS questionnaire, developed and validated by the PREDIMED group, comprising 12 questions about the frequency of food consumption and two questions regarding the Spanish population's typical eating habits. RESULTS: MDA was observed by 25% (17% men and 34% women). EVA was present in 17% (29% men and 4% women). The adjusted logistic regression models showed that an increase in MDA decreases the probability of EVA in the global analysis (OR = 0.36; 95% CI: 0.16-0.82). In the analysis by sex, this association was only seen in men (OR = 0.33; 95% CI: 0.12-0.86), but not in women (OR = 0.31; 95% CI: 0.04-2.50). CONCLUSION: The results of this study suggest that a greater adherence to the Mediterranean diet decreases the probability of presenting EVA. In the analysis by sex, this association applies only to men.

Multivariate Analysis of Influence of Vitamin Intake on Vascular Function Parameters by Sex in the General Spanish Population: EVA Study.

The influence of vitamin intake on vascular function parameters in the Spanish general population has not been studied. The main objective of this study is to analyze the influence of vitamin intake on vascular function and as a secondary objective the adequacy of vitamin intake in a sample of the Spanish population without previous cardiovascular disease and analyze the differences according to sex. Methods: We included 501 individuals obtained by simple random sampling with replacement (reference population 43,946). The average age was 55.90 ± 14.24 years, 49.70% men. Participants recorded the intake of vitamins using the EVIDENT app, previously validated, during a period of 3 days. Vascular function was assessed by measuring carotid-femoral pulse wave velocity (cfPWV) with the SphygmoCor device, cardio-ankle vascular index (CAVI) with the VaSera device and brachial-ankle pulse wave velocity (baPWV) by using a validated equation. Results: The vitamins with the least adequate intake was vitamin D, less than 5%, and vitamin B9, less than 35%. Vitamins with an adequate intake percentage, close to 100%, were B12 and B6. The multiple regression analysis showed a negative association between cfPWV and vitamin B2 in both sexes, and a positive one with retinol in men and B3 in women. baPWV was negatively associated with vitamins B1 and B12 in women and B9 in men, while being positively linked with B6 in men. CAVI presented a negative association with vitamin D in women. The results were similar in the canonical correspondence analysis. In conclusion, the results of this study suggest that the influence of vitamins on vascular function is not homogeneous and varies according to the parameter analyzed. Thus, in men, vitamins B2 and retinol were associated with cfPWV and vitamins B6 and B9 with baPWV. In women, vitamins B2 and B3 were related cfPWV, vitamins B1 and B12 with cfPWV and vitamin D with CAVI.

Automatic image analyser to assess retinal vessel calibre (ALTAIR). A new tool to evaluate the thickness, area and length of the vessels of the retina.

BACKGROUND AND OBJECTIVES: The examination of the fundus allows to evaluate retinal the microcirculation in vivo. We assess the reliability and validity of ALTAIR software, and to evaluate its clinical relevance by the association of thickness, area and length of the retinal vessels with other measures of vascular structure and function, target organ damage and cardiovascular risk. METHODS: Cross-sectional study involving a total of 250 subjects aged 62 ±â€¯9 years, 51 % males. In a random subsample of 60 subjects (118 retinographies), we estimated the intraobserver, interobserver and interdevice intraclass correlation coefficients (ICC) of the measurements of retinal vascular thickness, area and length in 3 concentric circles. Concurrent validity was assessed with all 250 subjects (495 retinographies), analysing the relationship to age, blood pressure, target organ damage, vascular structure and function, and cardiovascular risk. RESULTS: Of the sample, 69 % were diagnosed with hypertension and 17 % with diabetes. Intraobserver ICC ranged from 0.640 for venous length to 0.906 for arterial area. Interobserver ICC ranged from 0.809 for arterial length to 0.916 for venous area, and interdevice ICC for arteriovenous ratio (AVR) was 0.887, thickness of arteries 0.590 and vein thickness 0.677. We found a moderate correlation between retinal vascular parameters and vascular structure and function, and target organ damage. In multiple linear regression analysis, the association with blood pressure, albumin/creatinine ratio, carotid intima-media thickness and cardiovascular risk is maintained. CONCLUSION: The ALTAIR tool has been useful for analysing the thickness, area and length of retinal vessels, with adequate reliability and a concomitant association of retinal vessel measurements with other cardiovascular parameters and cardiovascular risk. Therefore, in addition to thickness, the area and length of retinal vessels could also play a role in the prediction of cardiovascular risk.

Postprandial effects of breakfast glycaemic index on cognitive performance among young, healthy adults: A crossover clinical trial.

Objective: To evaluate the postprandial effects of high and low glycaemic index (GI) breakfasts on cognitive performance in young, healthy adults.Methods: A crossover clinical trial including 40 young, healthy adults (aged 20-40 years, 50% females) recruited from primary healthcare centres in Salamanca, Spain. Verbal memory, phonological fluency, attention, and executive functions were examined 0, 60, and 120 minutes after consuming a low GI (LGI), high GI (HGI), or water breakfast. Every subject tried each breakfast variant, in a randomized order, separated by a washout period of 7 days, for a total of 3 weeks.Results: A significant interaction between the type of breakfast consumed and immediate verbal memory was identified (P<.05). We observed a trend towards better performance in verbal memory (delayed and immediate), attention, and phonological fluency following an LGI breakfast.Discussion: Cognitive performance during the postprandial phase in young, healthy adults was minimally affected by the GI of breakfast. The potential for breakfast's GI modulation to improve short- and long-term cognitive functioning requires further research.

Reclassification by applying the Framingham equation 30 years to subjects with intermediate cardiovascular risk. MARK study / Reclasificación utilizando la ecuación de Framingham a 30 años a sujetos con riesgo cardiovascular intermedio. Estudio MARK

Background and objective: The estimation of cardiovascular risk (CVR) with scores at 30 years old has a special interest in reclassifying in a suitable way <60 year subjects with intermediate CVR. This study analyzes what percentage of patients with intermediate CVR included in the MARK study is reclassified by applying the 30-year Framingham score (FS30). It also analyzes the degree of agreement between the two equations to classify high risk subjects. Patients and methods: Cross-sectional study of 966 subjects included in the MARK study. The CVR was calculated with the two versions of the FS30 (based on lipids and body mass index) for "hard" cardiovascular events in subjects with intermediate CVR. Results: The 59% and 61% of the subjects with intermediate CVR would be classified as if they had high CVR to undergo a hard event if we used the FS30 in both versions. 70% of men and 35% of women would be classified as high CVR (p<0.01). The agreement percentage, measured with the Kappa index, between the equations FS30L and FS30BMI to classify the high-risk subjects was 67.9% (in men 67.4% and in women 68.7%). Conclusions: In subjects with intermediate CVR the FS30 reclassifies more than the half as high RCV, 2 out of 3 men and 1 out of 3 women

Antecedentes y objetivo: La estimación del riesgo cardiovascular (RCV) con ecuaciones a 30 años tienen un interés especial para reclasificar de manera adecuada los sujetos de 60 años con RCV intermedio. Este estudio analiza qué porcentaje de pacientes con RCV intermedio incluido en el estudio MARK se reclasifica aplicando la puntuación de Framingham a 30 años (FS30) y grado de concordancia entre las 2 ecuaciones para clasificar a los sujetos de riesgo alto. Pacientes y métodos: Estudio transversal de 966 sujetos incluidos en el estudio MARK. El RCV se calculó con las 2 versiones del FS30 (basado en los lípidos y el índice de masa corporal) para eventos cardiovasculares «duros» en sujetos con RCV intermedio. Resultados: El 59 y el 61% de los sujetos con RCV intermedio se clasificarían como si tuvieran un RCV alto para sufrir un evento difícil si utilizáramos el FS30 en ambas versiones. El 70% de los varones y el 35% de las mujeres se clasificarían como RCV alto (p<0,01). El porcentaje de concordancia, medido con el índice Kappa, entre las ecuaciones FS30L y FS30BMI para clasificar a los sujetos de alto riesgo fue del 67,9% (en varones 67,4% y en mujeres 68,7%). Conclusiones: En sujetos con RCV intermedio, el FS30 reclasifica más de la mitad como RCV alto, 2 de cada 3 varones y una de cada 3 mujeres

Relationship between the presence of insomnia and walking physical activity and diet quality: A cross-sectional study in a sample of Spanish adults / Relación entre la presencia de insomnio y la actividad física caminando y la calidad de la dieta: un estudio transversal en una muestra de adultos españoles

Introduction and objectives: Certain lifestyle habits may influence aspects of sleep quality, such as insomnia. The main objective of the present study was to analyze the relationship of the presence of insomnia, with walking physical activity and diet quality in an adult population. Patients and methods: A cross-sectional descriptive study was performed (subanalysis of the TRIPLE A study) between January of 2014 to June of 2015. A total of 454 subjects were selected by consecutive sampling. Insomnia was evaluated with the Atenas scale, diet quality using the diet quality index (DQI) questionnaire, and physical activity using pedometers for seven days, evaluating the total number of steps, aerobic steps, and energy expended. Results: Of all patients, 26.8% presented with insomnia (33.8% in women and 17.5% in men). In a adjusted model, the mean differences of total steps/day, aerobic steps/day, and kilocalories/day spent in performing physical activity, between no insomnia group and insomnia group were: 1022.5 (95% CI: 177.9-1867.0), 743.9 (95% CI: 68.3-1419.4) and 39.8 (95% CI: 5.7-73.9), respectively. We did not find an association between the diet quality index (DQI) and insomnia. Conclusions: The findings suggest that completing daily a greater total number of steps, aerobic steps, and energy expended by walking, could be correlated with less insomnia, independent of age, sex, and other confounding variables. However, no relationship was observed between diet quality and insomnia

Introducción y objetivo: Ciertos hábitos y estilos de vida pueden influir en algunos aspectos de la calidad del sueño, como el insomnio. El objetivo principal del presente estudio fue analizar la relación de la presencia de insomnio, con la actividad física caminando y la calidad de la dieta en una población adulta. Pacientes y métodos: Se realizó un estudio descriptivo transversal (subanálisis del estudio TRIPLE A) desde enero de 2014 a junio de 2015. Se seleccionó una muestra de 454 sujetos mediante muestreo consecutivo. El insomnio fue evaluado con la escala Atenas, la calidad de la dieta mediante el cuestionario del índice de calidad de la dieta (DQI) y la actividad física mediante podómetros durante 7 días, evaluando el número de pasos totales, pasos aeróbicos y gasto energético. Resultados: Presentaron insomnio el 26,8% (el 33,8% en mujeres y el 17,5% en varones). Las diferencias de media de los pasos totales/día, pasos aeróbicos/día y las kilocalorías/día gastadas en la realización de la actividad física, entre el grupo de sujetos sin insomnio y el grupo de sujetos con insomnio fueron: 1.022,5 (IC 95%: 177,9-1.867,0), 743,9 (IC 95%: 68,3-1.419,4) y 39,8 (IC 95%: 5,7-73,9),respectivamente. No hemos encontrado asociación entre el DQI y el insomnio. Conclusiones: Un mayor número total de pasos, pasos aeróbicos y gasto energético gastado, realizando actividad física caminando, podría estar relacionado con menor presencia de insomnio, independientemente de la edad, sexo y otras variables de confusión. Sin embargo no se ha encontrado relación entre la calidad de la dieta y el insomnio

Acute effect of healthy walking on arterial stiffness in patients with type 2 diabetes and differences by age and sex: a pre-post intervention study.

BACKGROUND: Daily aerobic exercise such as healthy walking could have an immediate effect on parameters of arterial stiffness; however, there is little evidence in the diabetic population. Our aim, therefore, is to evaluate the association between healthy walking and acute effects on the parameters of arterial stiffness in subjects with type 2 diabetes. METHODS: The Effectiveness of a multifactorial intervention in diabetics study (EMID), is a study based on an application for smartphones, healthy walking and a nutritional workshop in patients with type 2 diabetes in primary care, is a randomized controlled trial of two parallel groups. This is a subanalysis of the intervention group to evaluate the response to the healthy walking according to age and sex, in 89 subjects with type 2 diabetes, aged between 40 and 70 years. The intervention was a 4 km of a healthy walking at low-moderate intensity. To value our aim, the main study variables were measured before and after it. RESULTS: The study population had an average age of 65.0 years (61.2-68.1). After the healthy walking, there was a decrease in the parameters of arterial stiffness: Cardio ankle vascular index (CAVI) of - 0.2 (95%CI:-0.4 to - 0.1) and pulse pressure (PP) of the lower extremities of - 3.9 mmHg (95%CI: -5.9 to - 2.0). Furthermore, in the lower extremities there was a decrease in systolic blood pressure of - 5.3 mmHg (95% CI: -7.3 mmHg to - 3.3 mmHg), in diastolic blood pressure of - 1.5 mmHg (95% CI: -2.6 mmHg to - 0.4 mmHg) (p < 0.05 for all). It is observed that males have an OR of 2.981 (IC = 95% 1.095 to 8.119) to achieve a reduction in the CAVI (p < 0.05) and an OR of 2.433 (95%CI: 0.871 to 6.794) in the ankle PP (p > 0.05), compared with females. CONCLUSIONS: The findings of this study suggest that daily aerobic exercise at a low to moderate intensity, such as healthy walking, has an immediate beneficial effect on the cardio-ankle vascular index, especially in males. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02991079 .

Effect of a multifactorial intervention on the increase in physical activity in subjects with type 2 diabetes mellitus: a randomized clinical trial (EMID Study).

BACKGROUND: Regular physical activity is essential for metabolic control in type 2 diabetes mellitus. AIMS: The aim of this study was to assess the short and long-term impact of a multifactorial intervention on physical activity and clinically relevant biochemical parameters in patients with type 2 diabetes mellitus. METHODS: This randomised, controlled clinical trial (NCT02991079) included two parallel groups aged 25-70 years from a primary care health centre in Salamanca, Spain. The subjects were assigned randomly (1:1) to control and intervention groups, using Epidat 4.0 software. Both were counselled on the importance of physical activity and maintaining a healthy diet. The intervention group also took five low-moderate intensity 4 km nurse-guided walks, received a smartphone application to promote healthy habits and attended a diet workshop. Physical activity was measured objectively using a pedometer and subjectively using a shortened international physical activity questionnaire (at baseline, 3 and 12 months). RESULTS: In total, 204 subjects were included (mean age 60.6 years, 45.6% were women). After 3 months, relative to the control group, the intervention group increased their daily number of steps by 1852, aerobic steps by 1623, distance walked by 994 m, and total metabolic equivalent minutes per week by 1297 and decreased sedentary time by 34.3 minutes per day. Differences from baseline persisted at 12 months, including mean increases of 1141 daily steps, 917 aerobic steps, and 1065 total metabolic equivalent minutes per week in the intervention group relative to the control group ( P<0.05 for all). CONCLUSIONS: The success of this multifactorial intervention should help inform future clinical approaches and application designs towards managing type 2 diabetes mellitus and improving patient outcomes.

Effectiveness of A Multifactorial Intervention in Increasing Adherence to the Mediterranean Diet among Patients with Diabetes Mellitus Type 2: A Controlled and Randomized Study (EMID Study).

The Mediterranean diet (MD) is recognized as one of the healthiest dietary patterns and has benefits such as improving glycaemic control among patients with type 2 diabetes (T2DM). Our aim is to assess the effectiveness of a multifactorial intervention to improve adherence to the MD, diet quality and biomedical parameters. The EMID study is a randomized and controlled clinical trial with two parallel groups and a 12-month follow-up period. The study included 204 subjects between 25⁻70 years with T2DM. The participants were randomized into intervention group (IG) and control group (CG). Both groups received brief advice about healthy eating and physical activity. The IG participants additionally took part in a food workshop, five walks and received a smartphone application for three months. The population studied had a mean age of 60.6 years. At the 3-month follow-up visit, there were improvements in adherence to the MD and diet quality of 2.2 and 2.5 points, compared to the baseline visit, respectively, in favour of the IG. This tendency of the improvement was maintained, in favour of the IG, at the 12-month follow-up visit. In conclusion, the multifactorial intervention performed could improve adherence to the MD and diet quality among patients with T2DM.

Capacity adiposity indices to identify metabolic syndrome in subjects with intermediate cardiovascular risk (MARK study).

BACKGROUND: Obesity increases mortality, and is linked to cardiovascular diseases and metabolic syndrome (MetS). Therefore, the purpose of this study was to analyze the ability of different adiposity indices to identify subjects with MetS among people with intermediate cariovascular risk. MATERIALS AND METHODS: The cross-sectional study involved 2478 subjects, recruited by the MARK study. Adiposity measures: general adiposity by body mass index (BMI), central adiposity by waist-to-height ratio (WHtR), fat mass percent by the Clínica Universidad de Navarra-body adiposity estimator (CUN-BAE), percentage of body fat and of visceral adipose tissue by body roundness index (BRI) and visceral obesity and general adiposity with body shape index (ABSI). The diagnosis of MetS was made in accordance with the criteria established in the international consensus of the Joint Scientific Statement National Cholesterol Education Program III. RESULTS: The highest correlation coefficients were obtained by the glycemic components (HbA1c and FPG) of the MetS and ranged from 0.155 to 0.320. The exception was ABSI, which showed lower values in the global analysis and in the males. Values of the area under the ROC curve with the adiposity indices ranged from 0.773 with the BMI in males to 0.567 with ABSI in males. In the logistic regression analysis, all adiposity factors, except ABSI, showed similar OR values of MetS after adjusting for possible confounding factors. In the global analysis, the adiposity index that showed a highest OR of MetS was CUN-BAE (OR 5.50; 95% CI 4.27-7.09). In the analysis by gender, the highest ORs were BMI in males (OR 5.98; 95% CI 4.70-7.60) and both WHtR and BRI in females (OR 4.15; 95% CI 3.09-5.58). CONCLUSION: All adiposity indices, except for ABSI, show an association with MetS and similar ability to detect subjects with MetS among people with intermediate cariovascular risk.

Relationship between the presence of insomnia and walking physical activity and diet quality: A cross-sectional study in a sample of Spanish adults.

INTRODUCTION AND OBJECTIVES: Certain lifestyle habits may influence aspects of sleep quality, such as insomnia. The main objective of the present study was to analyze the relationship of the presence of insomnia, with walking physical activity and diet quality in an adult population. PATIENTS AND METHODS: A cross-sectional descriptive study was performed (subanalysis of the TRIPLE A study) between January of 2014 to June of 2015. A total of 454 subjects were selected by consecutive sampling. Insomnia was evaluated with the Atenas scale, diet quality using the diet quality index (DQI) questionnaire, and physical activity using pedometers for seven days, evaluating the total number of steps, aerobic steps, and energy expended. RESULTS: Of all patients, 26.8% presented with insomnia (33.8% in women and 17.5% in men). In a adjusted model, the mean differences of total steps/day, aerobic steps/day, and kilocalories/day spent in performing physical activity, between no insomnia group and insomnia group were: 1022.5 (95% CI: 177.9-1867.0), 743.9 (95% CI: 68.3-1419.4) and 39.8 (95% CI: 5.7-73.9), respectively. We did not find an association between the diet quality index (DQI) and insomnia. CONCLUSIONS: The findings suggest that completing daily a greater total number of steps, aerobic steps, and energy expended by walking, could be correlated with less insomnia, independent of age, sex, and other confounding variables. However, no relationship was observed between diet quality and insomnia.

Noninvasive validation of central and peripheral augmentation index estimated by a novel wrist-worn tonometer.

BACKGROUND: The validation of new blood pressure devices with easier use and more rapid data collection may facilitate the incorporation of these measures into clinical practice. We analyze the reliability and validity of Pulse Wave Analysis as reported by a novel wrist-worn device, easy and quick to use, comparing central and peripheral augmentation index (AIx) with the same measures from the SphygmoCor. Additionally, we analyzed clinical relevance through the association of the Pulse Wave Analysis, as reported by a novel wrist-worn device, with other cardiovascular parameters. METHODS: Cross-sectional study including 254 participants. Mean age was 51.9 ±â€Š13.4 years and 53% were women. MEASUREMENTS: peripheral AIx (PAIx) and central AIx (CAIx) by the wrist-worn device and SphygmoCor (MM3); carotid-femoral (cf) pulse wave velocity (PWV) by SphygmoCor (MM3); cardioankle-vascular index (CAVI), ankle-brachial index (ABI) and brachial-ankle (ba) PWV by the Vasera device and carotid-intima media thickness (IMT) by ultrasonography. RESULTS: Intra-observer intra-class correlation coefficient (ICC) for PAIx was 0.886 (95% CI 0.803-0.934) and for CAIx 0.943 (95% CI 0.901-0.968) with Bland Altman limits of agreement -0.75 (-23.8 to 21.8) and 0.08 (-15.7 to 15.9), respectively. Inter-observer ICC for PAIx was 0.952 (95% CI 0.915-0.972) and CAIx 0.893 (95% CI 0.811-0.939) with limits of agreement -0.45 (-13.7 to 12.8) and 0.43 (-17.7 to 18.5), respectively. Comparing the wrist-worn device with SphygmoCor, the ICC was 0.849 (95% CI 0.798-0.887) for PAIx, and 0.783 (95% CI 0.711-0.838) for CAIx. In Bland-Altman, limits of agreement for PAIx 1.03 (-20.67 to 22.73), and for CAIx -2.14 (-24.79 to 20.50). PAIx and CAIx, from the wrist-worn device, correlated with age, CAVI, ABI, baPWV, cfPWV, IMT, glomerular filtration and cardiovascular risk. CONCLUSION: AIx measurements by wrist-worn device shows a good intra-observer and inter-observer reliability, inter-device noninvasive reliability and validity when compared with SphygmoCor, and clinical relevance by association with measures of vascular structure and function, end-organ damage and cardiovascular risk.

Short- and long-term effectiveness of a smartphone application for improving measures of adiposity: A randomised clinical trial - EVIDENT II study.

BACKGROUND: Evidence on the efficacy of smartphone applications (apps) for reducing body weight and other measurements of adiposity sustainably is not conclusive. OBJECTIVE: To evaluate the effect of adding an app for 3 months to traditional counselling on physical activity (PA) and a heart-healthy diet for the modification of measurements of adiposity at 3 and 12 months after intervention. METHODS: This randomised clinical trial included 833 subjects. The counselling and app group (IG) had 415 subjects, while 418 were included in the counselling only group (CG). The primary outcome was adiposity measurements at 3 and 12 months after intervention. The secondary outcome was the effect of the intervention by sex. INTERVENTION: Counselling on a heart-healthy diet and PA was given to both groups. The IG also received training in the use of a smartphone app designed to promote a heart-healthy diet and PA, and this group was given access to this application for 3 months. Outcome measurements included waist circumference (WC), body mass index (BMI) and Clínica Universidad de Navarra - body adiposity estimator (CUN-BAE). RESULTS: In the IG at 12 months, the following decreased: WC -0.72 cm (95% confidence interval [CI]: -2.35 to -0.02) and CUN-BAE -0.35 (95% CI: -0.63 to -0.06). These decreases were only observed in women. After baseline adjustment, the beneficial effect was maintained in the IG compared to the CG at 12 months in terms of WC (-0.67; 95% CI: -0.29 to -0.02) and CUN-BAE (-0.57; 95% CI: -1.10 to -0.04), but only in women. CONCLUSIONS: An intervention of nutritional counselling and PA plus the smartphone app with personalised recommendations compared to CG showed beneficial results in terms of reduction of abdominal obesity and the percentage of body fat in women, but not in men.

Behavioural intervention to reduce resistance in those attending adult day care centres: PROCENDIAS study protocol for a randomized clinical trial.

AIM: This study evaluates the effectiveness of a behavioural intervention programme aimed at reducing the reluctance of dependent people to attend Adult Day Care Centres. We hope that reducing resistance will have a positive influence on the mental health of caregivers. BACKGROUND: Care centres offer important relief and rest services for family caregivers. Some caregivers report being affected by behavioural and psychological symptoms of dementia when they prepare dependents for the Care Centres, especially when these have dementia. Caregivers often report the need for information about how to manage the behaviour of the sick. Nurses in community healthcare units can investigate cases of patients who present resistance when attending care centres and can promote the use of interventions aimed at reducing this problem. DESIGN: Randomised controlled clinical trial. METHODS: The reference population will be care centre users in Salamanca (Spain) to select 120 family members responsible for the preparation and transfer of the care-recipient. Each participant will be randomised to an intervention group or control group (standard care). A baseline assessment and 6 months follow-up assessment will be performed (study approved in September 2016). INTERVENTION: The intervention group will consist of 8 sessions, one per week, each lasting 90 min. Each session will be run by a psychologist trained in behaviour analysis and will be tailored to the specific behavioural problems reported by the caregivers. DISCUSSION: The results of a previously published pilot study allow us to be optimistic about the possibilities of a brief intervention.

Perceived Emotional Intelligence and Learning Strategies in Spanish University Students: A New Perspective from a Canonical Non-symmetrical Correspondence Analysis.

Recent studies have revealed that emotional competences are relevant to the student's learning process and, more specifically, in the use of learning strategies (LSs). The aim of this study is twofold. First, we aim to analyze the relationship between perceived emotional intelligence (PEI) and LSs applying the scales TMMS-24 and Abridged ACRA to a sample of 2334 Spanish university students, whilst also exploring possible gender differences. Second, we aim to propose a methodological alternative based on the Canonical non-symmetrical correspondence analysis (CNCA), as an alternative to the methods traditionally used in Psychology and Education. Our results show that PEI has an impact on the LS of the students. Male participants with high scores on learning support strategies are positively related to high attention, clarity, and emotional repair. However, the use of cognitive and control LS is related to low values on the PEI dimensions. For women, high scores on cognitive, control, and learning support LS are related to high emotional attention, whereas dimensions such as study habits and learning support are related to adequate emotional repair. Participants in the 18-19 and 22-23 years age groups showed similar behavior. High scores on learning support strategies are related to high values on three dimensions of the PEI, and high values of study habits show high values for clarity and low values for attention and repair. The 20-21 and older than 24 years age groups behaved similarly. High scores on learning support strategies are related to low values on clarity, and study habits show high values for clarity and repair. This article presents the relationship between PEI and LS in university students, the differences by gender and age, and CNCA as an alternative method to techniques used in this field to study this association.

Adiposity measures and arterial stiffness in primary care: the MARK prospective observational study.

BACKGROUND: The cardiovascular risk of obesity is potentially increased by arterial stiffness. OBJECTIVE: To assess the relationship of adiposity measures with arterial stiffness in Caucasian adults with intermediate cardiovascular risk. SETTING: Six Spanish health centres. PARTICIPANTS: We enrolled 2354 adults (age range, 35-74 years; mean age, 61.4±7.7 years, 61.9% male). METHODS: This is a cross-sectional study that analyses data from the baseline visit of the improving interMediAte RisK management (MARK) study. The main outcome variables were body mass index (BMI), waist-to-height ratio (WHtR), Clínica Universidad de Navarra-body adiposity estimation (CUN-BAE) body fat percentage and body roundness index (BRI). Vascular function was assessed by the cardio-ankle vascular index (CAVI) with the VaSera device; brachial-ankle pulse wave velocity (baPWV) was determined using a validated equation. RESULTS: The mean adiposity measures were a BMI of 29.2±4.4, WHtR of 0.61±0.07, CUN-BAE of 35.7±1.7 and BRI of 5.8±1.7. The mean stiffness measures were a CAVI of 8.8±1.2 and baPWV of 14.9±2.5. In multiple linear regression analyses, all adiposity measures were negatively associated with CAVI and baPWV (p<0.01 for all) after adjustment for possible factors of confusion. The proportion of CAVI variability via the adiposity measures were 5.5% for BMI, 5.8% for CUN-BAE, 3.8% for WHtR and 3.7% for BRI. These were higher among diabetic, obese, younger (≤62 years) and non-hypertensive subjects who had similar activity and sedentary profiles. CONCLUSIONS: Adiposity measures are negatively associated with arterial stiffness measures. The percentage of variation in CAVI explained by its relation to the different measures of adiposity ranges from 5.8% (CUN-BAE) to 3.7% (BRI). In the case of baPWV, it oscillates between 0.7% (CUN-BAE and BMI) and 0.1% (WHtR). TRIAL REGISTRATION NUMBER: NCT01428934.
