OPENCRONIC Study. Knowledge and experiences of Spanish patients and carers about chronic disease

Background: Chronic diseases are currently the main cause of morbidity and mortality and represent a major challenge to healthcare systems. The objective of this study is to know Spanish public opinion about chronic disease and how it affects their daily lives. Methods: Through a telephone or online survey of 24 questions, data was gathered on the characteristics of the respondents and their knowledge and experiences of chronic diseases. Results: Of the 2522 survey respondents, 325 had a chronic disease and were carers, 1088 had a chronic disease and were not carers, 140 did not have a chronic disease but were carers, and 969 did not have chronic disease and were not carers. The degree of knowledge on these diseases was good or very good for 69.4%, 56.0%, 62.2%, and 46.7%, respectively, for each group. All the groups agreed that chronic diseases mainly affect mood, quality of life and having to make sacrifices. Conclusions: Knowledge about chronic diseases is relatively good, although it can be improved among the Spanish population, especially among patients who report having a chronic disease and play the role of carers. However, it is important to continue maintaining the level of information and training concerning these diseases.Boehringer Ingelheim España, S.

Physical activity and metabolic syndrome in primary care patients in Spain

[EN] To determine the relationship between self-reported physical activity and the components of premorbid metabolic syndrome in patients treated in primary care according to sex. Methods Cross-sectional descriptive study conducted on a sample of 2,359 patients without cardiovascular disease or diabetes, included in the cohort of the IBERICAN study. Using ANOVA models and adjusting for age, economic status, employment situation, level of education, adherence to a Mediterranean diet, tobacco use and alcohol consumption, we estimated the association of the variables blood pressure, triglycerides, HDL cholesterol, blood glucose and waist circumference with the self-reported level of physical activity (sedentary, moderate, high, very high). The analyses were performed stratifying by sex. Results A total of 854 men and 1,505 women with no identified diseases were included. Women were more sedentary than men (p<0.004; OR = 1,35; IC95% = 1,10–1,65) and presented lower values in all the components of the metabolic syndrome, except for HDL-cholesterol, which was higher (p<0.001). The adjusted ANOVA model shows that diastolic blood pressure, triglycerides, fasting blood glucose, and waist circumference were significantly lower the higher the level of physical activity in both men and women (p<0.05). Conclusions. Patients served in primary care clinics without diabetes or cardiovascular disease and with high levels of physical activity showed better metabolic syndrome profiles. Given that women are more sedentary, gender approaches are needed in the promotion of physical activity to prevent metabolic syndrome and cardiovascular disease.S

Clinical characteristics, treatment, and blood pressure control in patients with hypertension seen by primary care physicians in Spain: the IBERICAN study

Objectives: To determine the clinical profile, according to the history of hypertension, the risk of developing hypertension, current antihypertensive treatment and BP control rates in patients with hypertension from the IBERICAN cohort. Methods: IBERICAN is an ongoing prospective cohort study, whose primary objective is to determine the frequency, incidence, and distribution of CVRF in the adult Spanish population seen in primary care settings. This analysis shows the baseline clinical characteristics of patients with hypertension. Adequate BP control was defined as BP <140/90 mmHg according to 2013 ESH/ESC guidelines. Results: A total of 8,066 patients were consecutively included, of whom 3,860 (48.0%) had hypertension. These patients were older (65.8 ± 10.9 vs. 51.6 ± 14.7 years; p < 0.001), had more cardiovascular risk factors, target organ damage and cardiovascular disease (CVD) in comparison with those without hypertension. The risk of hypertension increased with the presence of associated CV risk factors and comorbidities, particularly diabetes, obesity and the metabolic syndrome, and decreased with the intensity of physical activity. Regarding antihypertensive treatments, 6.1% of patients did not take any medication, 38.8% were taking one antihypertensive drug, 35.5% two drugs, and 19.6% three or more antihypertensive drugs. Overall, 58.3% achieved BP goals <140/90 mmHg. A greater probability of BP control was observed with increasing age of patients and the greater number of antihypertensive drugs. Blood pressure control was lower in hypertensive patients with diabetes, obesity, the metabolic syndrome, increased urinary albumin excretion, higher pulse pressure, and lack of antihypertensive treatment. Conclusions: About half of patients attended in primary care settings have hypertension in Spain. Patients with hypertension have a worse CV clinical profile than non-hypertensive patients, with greater association of CVRF and CVD. Around four out of ten patients do not achieve the recommended BP goals, and higher use of combination therapies is associated with a better BP control

Prevalence of Hyperuricemia and Its Association with Cardiovascular Risk Factors and Subclinical Target Organ Damage

The role of uric acid levels in the cardiovascular continuum is not clear. Our objective is to analyze the prevalence of hyperuricemia (HU) and its association with cardiovascular risk factors (CVRF), subclinical target organ damage (sTOD), and cardiovascular diseases (CVD). We evaluated the prevalence of HU in 6.927 patients included in the baseline visit of the IBERICAN study. HU was defined as uric acid levels above 6 mg/dL in women, and 7 mg/dL in men. Using adjusted logistic regression models, the odds ratios were estimated according to CVRF, sTOD, and CVD. The prevalence of HU was 16.3%. The risk of HU was higher in patients with pathological glomerular filtration rate (aOR: 2.92), heart failure (HF) (aOR: 1.91), abdominal obesity (aOR: 1.80), hypertension (HTN) (aOR: 1.65), use of thiazides (aOR: 1.54), left ventricular hypertrophy (LVH) (aOR: 1.36), atrial fibrillation (AFIB) (aOR: 1.29), and albuminuria (aOR: 1.27). On the other hand, being female (aOR: 0.82) showed a reduced risk. The prevalence of HU was higher in men, in patients presenting CVRF such as HTN and abdominal obesity, and with co-existence of LVH, atrial fibrillation (AFIB), HF, and any form of kidney injury. These associations raise the possibility that HU forms part of the early stages of the cardiovascular continuum. This may influence its management in Primary Healthcare because the presence of HU could mean an increased CV risk in the patients

Isotemporal substitution of inactive time with physical activity and time in bed: cross-sectional associations with cardiometabolic health in the PREDIMEDPlus study

Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m2) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had ≥3 components of the metabolic syndrome. Inactive time, physical activity and time in bed were objectively determined using triaxial accelerometers GENEActiv during 7 days (ActivInsights Ltd., Kimbolton, United Kingdom). Multiple adjusted linear and logistic regression models were used. Isotemporal substitution regression modelling was performed to assess the relationship of replacing the amount of time spent in one activity for another, on each outcome, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Results: Inactive time was associated with indicators of obesity and the metabolic syndrome. Reallocating 30 min per day of inactive time to 30 min per day of time in bed was associated with lower BMI, waist circumference and glycated hemoglobin (HbA1c) (all p-values < 0.05). Reallocating 30 min per day of inactive time with 30 min per day of LPA or MVPA was associated with lower BMI, waist circumference, total fat, visceral adipose tissue, HbA1c, glucose, triglycerides, and higher body muscle mass and HDL cholesterol (all p-values < 0.05). Conclusions: Inactive time was associated with a poor cardio-metabolic profile. Isotemporal substitution of inactive time with MVPA and LPA or time in bed could have beneficial impact on cardio-metabolic health

Particle swarm grammatical evolution for energy demand estimation

El Enjambre Gramatical es un algoritmo de búsqueda y optimización perteneciente a la familia más general de la Evolución Gramatical, que trabaja con un conjunto de soluciones denominadas individuos o partículas. Utiliza el algoritmo de Optimización por Enjambre de Partículas como motor de búsqueda en la evolución de soluciones. En este trabajo presentamos un algoritmo de Enjambre Gramatical para la estimación de la demanda total de energía en un país a partir de variables macroeconómicas. Cada partícula del Enjambre Gramatical codifica un modelo diferente para la estimación de la demanda energética, que será decodificado por una gramática predefinida. Los parámetros del modelo también son optimizados por el algoritmo propuesto, de forma que el modelo se ajusta a un conjunto de entrenamiento de datos reales de demanda energética, seleccionando las variables más apropiadas para aparecer en el modelo. Analizamos el rendimiento de la evolución del Enjambre Gramatical en dos problemas reales de estimación de la demanda energética a un año vista en España y Francia. La propuesta se compara con enfoques anteriores con resultados competitivos.Depto. de Arquitectura de Computadores y AutomáticaFac. de InformáticaTRUEpu

Prevalence of obesity in primary care patients : the IBERICAN study

-Background and aims : Obesity has an important role in the prognosis of the patients, and important regional differences were described in Spain. The aim is to determine the prevalence of obesity in Spanish primary care patients and its geographical distribution. -Methods and results : Prevalence study that included patients from the baseline interview of the IBERICAN study. Obesity was defined as a body mass index (BMI) greater than or equal to 30 kg/m2 and abdominal obesity as a WC greater than or equal to 102 cm in men and 88 cm in women. Prevalence risks were calculated using unconditional logistic regression models, adjusting for socio-demographic variables and lifestyles. 58.8 % of the patients were obese according to any of the criteria used and 30.5 % met both criteria simultaneously. 33.7 % had a BMI greater than or equal to 30 kg/m2 and 55.6 % had abdominal obesity. Women, older patients, rural residents, and retirees presented a higher risk of obesity. On the other hand, a higher economic status or education, regular exercise and high adherence to a Mediterranean diet were protective factors. The prevalence of obesity was heterogeneously distributed, and Canary Islands, Cantabria and Castilla la Mancha had significantly high risks of combined obesity (aOR = 1.80; 1.50 and 1.46 respectively). -Conclusions : Obesity is a highly prevalent disease in primary care patients, with significant geographical differences in Spain

Estimation of the population atributable fraction due a to excess body fat in primary care patients : IBERICAN study

The burden of disease attributable to excess body fat (EBF) in type 2 diabetes mellitus (T2DM) may be underestimated due to problems correlating BMI with body fat. The aim of this study is to compare the population attributable fraction (PAF) of EBF in T2DM assessed with various parameters. Material and methods : Prevalence study based on the baseline visit of the IBERICAN study. Mixed unconditional logistic regression models were used to estimate the risk of T2DM for the various categories of BMI, of the estimation of EBF according to the CUN-BAE (Clínica Universidad de Navarra-Body Adiposity Estimator) and of waist circumference (WC), stratifying by sex. The PAF was calculated for each of the EBF estimates. Results : A total of 7752 patients from IBERICAN study were eligible, of them 1536 (19.8 %) achieved T2DM criterion, The prevalence of diabetes was higher in men, in those with a lower level of education, and in those who reported a low level of physical activity. Subjects with diabetes were older, had a higher BMI, a higher CUN-BAE-estimated body fat percentage (eBFP) and a higher waist circumference. One in three cases T2DM risk was attributed to elevated BMI, whereas in the CUN-BAE case it was attributed to 9 out of 10 men and 2 out of 3 women. One out of two cases of T2DM in women, and less in men, was attributed to an excess WC. Conclusions : The burden of disease attributable to EBF in the case of T2DM may be underestimated. Therefore, EBF should be used, together with BMI, WC -especially in women-, and the CUN-BAE to better estimate the risk of T2DM and to adapt dietary or lifestyle recommendations in daily clinical practice
