Incidence and prevalence of headache in influenza: A 2010-2021 surveillance-based study.

BACKGROUND AND PURPOSE: Influenza is a common cause of acute respiratory infection, with headache being one of the symptoms included in the European Commission case definition. The prevalence of headache as a symptom of influenza remains unknown. We aimed to describe the incidence and prevalence of headache in patients with influenza. METHODS: All consecutive patients who met the definition criteria of influenza-like illness during the influenza seasons 2010-2011 through 2021-2022 were included. The seasonal cumulative incidence of influenza per 1000 patients at risk and the prevalence of headache as an influenza symptom were calculated, including the 95% confidence intervals (CIs). Subgroup analyses were done based on patients' sex, age group, microbiological confirmation, vaccination status, and influenza type/subtype/lineage. RESULTS: During the study period, 8171 patients were eligible. The incidence of headache in the context of influenza varied between 0.24 cases per 1000 patients (season 2020-2021) and 21.69 cases per 1000 patients (season 2017-2018). The prevalence of headache was 66.1% (95% CI = 65.1%-67.1%), varying between 49.6% (season 2021-2022) and 80.1% (season 2010-2011). The prevalence of headache was higher in women (67.9% vs. 65.7%, p = 0.03) and higher in patients between 15 and 65 years old. Headache was more prevalent in patients infected with B subtypes than A subtypes (68.7% vs. 56.9%, p < 0.001). There were no notable differences regarding vaccination status or microbiological confirmation of the infection. CONCLUSIONS: Headache is a common symptom in patients with influenza, with a prevalence higher than that observed in other viral infections.

Health and wellbeing status of the long-lived individuals of the Spanish LONGECYL cross-sectional study.

BACKGROUND: The increase in life expectancy and long-lived individuals is a challenge for public health and provides an opportunity to understand the determinants of longevity. However, few studies have addressed the factors associated with the health status and quality of life in a long-lived individual population. We described the perceived health, clinical status, quality of life, and dependency for activities of daily living in a representative population in Castile and Leon, Spain. METHODS: A sample of 759 long-lived individuals aged 95 years and older was studied by the Health Sentinel Network of Castile and Leon (Spain) through a health examination and a structured questionnaire covering quality of life (EQ-5D-3), lifestyle habits, diet, working life and family health. A blood sample was taken for the study of biological and genetic markers. Chi Square and logistic regression OR with 95% confidence intervals were used to analyze the determinants of the long-lived individuals' health status. The significant level for the bivariate analysis was established at 0.05. RESULTS: Perceived health was good, very good or excellent in 64.2%, while only 46.0% had a quality-of-life index above 0.5 (ranging from 0 to 1) and 44.1% maintained acceptable independence for activities of daily living. Quality-of-life index was higher in the oldest, (OR 7.98 [2,32-27.41]) above 100 years compared to those under 98, and men had better values for independence than women (OR 2.43 [1.40-4.29]). Cardiovascular diseases were the most prevalent (85.5%), but neurological and mental diseases and vision problems had the highest impact on quality of life and independence. CONCLUSION: The long-lived individuals of Castile and Leon have a relatively well-preserved health status, although the perception of health is higher than that describing their quality of life and dependence. The quality of life was higher in the oldest age group and showed differences according to sex, with a better quality of life in men. Public health policies and programs should take in account the differences by sex and age as well as the prevention and control of the main conditions related with poor quality of life or dependence. Future research must include the interaction among genetic, socioeconomic, environmental, and other clinical factors in the quality of life and disability of long-lived individuals.

Factors associated to the presence of headache in patients with influenza infection and its consequences: a 2010-2020 surveillance-based study.

Headache is a common symptom of influenza infection; however, its causes and consequences remain uncertain. In this manuscript, we analyzed which demographic and clinical factors were associated with the presence of headache during the course of influenza infection and whether patients with headache had a different prognosis, evaluated by need of hospitalization, sick leave or school absenteeism. The influence study (NCT05704335) was an observational study that analyzed data routinely collected from the Health Sentinel Network between 2010 and 2020. During the study period, 7832 cases were considered, among which, 5275 (67.4%) reported headache. The presence of headache was independently associated with myalgia (2.753; 95%CI: 2.456-3.087, P < 0.001), asthenia (OR: 1.958; 95%CI: 1.732-2.214, P < 0.001), shivering (OR: 1.925; 95%CI: 1.718-2.156, P < 0.001), nasopharyngeal erythema (OR: 1.505; 95%CI: 1.293-1.753, P < 0.001), fever (OR: 1.469; 95%CI: 1.159-1.861; P = 0.001), sudden onset of symptoms (OR: 1.380; 95%CI: 1.120-1.702, p = 0.004), female sex (OR: 1.134; 95%CI: 1.023-1.257, P = 0.018), and gastrointestinal symptoms (OR: 1.169; 95%CI: 1.039-1.315; P = 0.01). Patients with headache had a sex and age adjusted lower odds of being referred to the hospital (OR: 0.463; 95%CI: 0.264-0.812, P = 0.007) and a higher odd of having a sick leave and/or school absenteeism (absenteeism (OR: 1.342; 95%CI: 1.190-1.514, P < 0.001). In conclusion, the presence of headache seems associated with symptoms caused by the innate immune response. These findings support a headache pathophysiology linked with the innate immune response. Due to the potential negative consequences and its treatable nature, clinicians should systematically evaluate it and, whenever necessary, treat it too.

InfluenCEF study: Clinical phenotype and duration of headache attributed to influenza infection.

INTRODUCTION: Headache is a frequent symptom of infections. We aimed to characterize the clinical phenotype and duration of headache attributed to influenza infection. METHODS: Prospective cohort study done in 53 primary care centers between January and April 2023. Patients were included if they had a confirmed influenza diagnosis, were older than 15 years and had a new-onset headache. Patients' demographics, prior medical history, headache phenotype and duration, associated symptoms and patients' outcomes were assessed. The International Classification of Headache Disorders criteria for headache attributed to a systemic viral infection, migraine and tension-type headache were assessed. RESULTS: Of the 478 patients 75 fulfilled eligibility criteria. The mean age was 43, 56% were men, and 27% had a prior headache history. The headache phenotype was a bilateral headache (52%), with frontal topography (48%), pressing quality (61%), moderate intensity, rhinorrhea (79%), nasal congestion (76%), and photophobia (59%). All patients fulfilled headache attributed to acute systemic viral infection criteria, 43% fulfilled migraine criteria and 31% tension-type headache criteria. The median duration of the headache was four (Inter-quartile range: two-six) days. CONCLUSION: The clinical phenotype of headache attributed to influenza infection was similar to other infections, with more pronounced cranial autonomic symptoms. The headache was an early symptom and was self-limited within a few days.Trial Registration: The study protocol is registered in ClinicalTrial.gov (NCT05704335).

Comprehensive surveillance of acute respiratory infections during the COVID-19 pandemic: a methodological approach using sentinel networks, Castilla y León, Spain, January 2020 to May 2022.

BackgroundSince 1996, epidemiological surveillance of acute respiratory infections (ARI) in Spain has been limited to seasonal influenza, respiratory syncytial virus (RSV) and potential pandemic viruses. The COVID-19 pandemic provides opportunities to adapt existing systems for extended surveillance to capture a broader range of ARI.AimTo describe how the Influenza Sentinel Surveillance System of Castilla y León, Spain was rapidly adapted in 2020 to comprehensive sentinel surveillance for ARI, including influenza and COVID-19.MethodsUsing principles and methods of the health sentinel network, we integrated electronic medical record data from 68 basic surveillance units, covering 2.6% of the regional population between January 2020 to May 2022. We tested sentinel and non-sentinel samples sent weekly to the laboratory network for SARS-CoV-2, influenza viruses and other respiratory pathogens. The moving epidemic method (MEM) was used to calculate epidemic thresholds.ResultsARI incidence was estimated at 18,942 cases per 100,000 in 2020/21 and 45,223 in 2021/22, with similar seasonal fold increases by type of respiratory disease. Incidence of influenza-like illness was negligible in 2020/21 but a 5-week epidemic was detected by MEM in 2021/22. Epidemic thresholds for ARI and COVID-19 were estimated at 459.4 and 191.3 cases per 100,000 population, respectively. More than 5,000 samples were tested against a panel of respiratory viruses in 2021/22.ConclusionExtracting data from electronic medical records reported by trained professionals, combined with a standardised microbiological information system, is a feasible and useful method to adapt influenza sentinel reports to comprehensive ARI surveillance in the post-COVID-19 era.

Influenza surveillance: determining the epidemic threshold for influenza by using the Moving Epidemic Method (MEM), Montenegro, 2010/11 to 2017/18 influenza seasons.

BACKGROUND: In 2009, an improved influenza surveillance system was implemented and weekly reporting to the World Health Organization on influenza-like illness (ILI) began. The goals of the surveillance system are to monitor and analyse the intensity of influenza activity, to provide timely information about circulating strains and to help in establishing preventive and control measures. In addition, the system is useful for comparative analysis of influenza data from Montenegro with other countries. AIM: We aimed to evaluate the performance and usefulness of the Moving Epidemic Method (MEM), for use in the influenza surveillance system in Montenegro. METHODS: Historical ILI data from 2010/11 to 2017/18 influenza seasons were modelled with MEM. Epidemic threshold for Montenegro 2017/18 season was calculated using incidence rates from 2010/11-2016/17 influenza seasons. RESULTS: Pre-epidemic ILI threshold per 100,000 population was 19.23, while the post-epidemic threshold was 17.55. Using MEM, we identified an epidemic of 10 weeks' duration. The sensitivity of the MEM epidemic threshold in Montenegro was 89% and the warning signal specificity was 99%. CONCLUSIONS: Our study marks the first attempt to determine the pre/post-epidemic threshold values for the epidemic period in Montenegro. The findings will allow a more detailed examination of the influenza-related epidemiological situation, timely detection of epidemic and contribute to the development of more efficient measures for disease prevention and control aimed at reducing the influenza-associated morbidity and mortality.

Prevalencia de sobrepeso y obesidad infantil. Estudio de una cohorte en Castilla y León, España / Prevalence of overweight and obesity in child population. A study of a cohort in Castile and Leon, Spain

Introducción: Varios estudios advierten que el sobrepeso y la obesidad se han convertido en una epidemia con graves consecuencias sobre la salud de la población. El objetivo del presente estudio es estimar la prevalencia de sobrepeso y obesidad en Castilla y León en una muestra de niños a los 6, 11 y 14 años de edad, describir su evolución y su asociación con hábitos de vida y antecedentes. Metodología: Estudio observacional, de cohorte retrospectivo, realizado por los pediatras de la Red Centinela Sanitaria, que se enmarca en un proyecto conjunto con el Centro Nacional de Investigación sobre la Evolución Humana de Burgos para conocer el patrón de crecimiento y desarrollo de la población infantil de Castilla y León. En 2012 se realizó un examen de salud y una recogida retrospectiva a partir de la historia clínica en una muestra de 326 niños, de la cohorte de nacidos en 1998. Resultados: Según los criterios de la OMS, a los 14 años había un 25,3% de sobrepeso entre los niños y un 18,5% entre las niñas. En cuanto a la obesidad, esta afectaba al 8,2 y 4,8%, respectivamente. A los 11 años se produce un pico de sobrepeso en las niñas y de obesidad en los niños. El entorno urbano-no urbano, la calidad y duración del sueño, así como el índice de masa corporal (IMC) de los padres han sido algunos de los factores asociados con el peso de los niños. Discusión: En Castilla y León, como en otras poblaciones de nuestro entorno, existe un grave problema de sobrepeso y obesidad infantil. Para su control, es necesario profundizar sobre los estilos de vida y los antecedentes relacionados con el nacimiento, así como el cálculo de la velocidad de crecimiento en la edad pediátrica

Hipotiroidismo subclínico en una muestra oportunista de la población de Castilla y León / Prevalence and clinical characteristics of subclinical hypothyroidism in an opportunistic sample in the population of Castile-León (Spain)

Objetivo: Describir la distribución de los valores de la hormona estimulante del tiroides (TSH) y estimar la prevalencia de hipotiroidismo subclínico en la población adulta de Castilla y León. Material y método: Estudio observacional en 45 consultas de medicina de familia de Castilla y León seleccionadas de manera oportunista. Se determinó la TSH en sueros, recogidos por cualquier motivo, de personas ≥35 años de edad. Se realizó análisis de confirmación, incluyendo la tiroxina libre y los anticuerpos antitiroperoxidasa. Resultados: Se realizaron 3957 análisis. El 63,4% eran mujeres. La edad media fue de 61,5 años. La mediana de los valores de TSH fue de 2,3 ¿UI/mL (2, ¿UI/mL en mujeres y 2,1 ¿UI/mL en hombres), con tendencia ascendente con la edad. Los valores de TSH son mayores en los hipotiroidismos subclínicos desconocidos o sin tratamiento que en los tratados. Los valores más bajos se observan en los sujetos eutiroideos. La prevalencia de hipotiroidismo subclínico fue del 9,2% (intervalo de confianza del 95%: 8,3-10,2); en las mujeres fue el triple que en los hombres (12,4% frente a 3,7%) y aumenta con la edad, con un máximo del 16,9% en las mujeres de 45 a 64 años. Conclusiones: La prevalencia estimada de hipotiroidismo subclínico es alta, en los límites superiores reflejados en la literatura. La posibilidad de progresión a hipotiroidismo manifiesto, así como la asociación con diversas enfermedades y factores de riesgo, aconsejan una gestión adecuada de su diagnóstico y tratamiento (AU)

Objective: To describe the distribution of thyroid-stimulating hormone (TSH) values and to estimate the prevalence of subclinical hypothyroidism in the adult population of Castile and León (Spain). Method: An observational study was conducted in an opportunistic sample of 45 primary care centers in Castile and León. TSH was determined in people aged ≥35 years that attended a primary care physician and had a blood test for any reason. Confirmatory analysis included free thyroxine and anti-thyroid peroxidase antibody determination. Results: A total of 3957 analyses were carried out, 63% in women. The mean age was 61.5 years. The median TSH value was 2.3 ¿IU/mL (2.5 ¿IU/mL in women and 2.1 ¿IU/mL in men), with a rising trend with age. TSH values were higher in undiagnosed or untreated subclinical hypothyroidism than in patients under treatment. The lowest levels were found in euthyroidism. The prevalence of subclinical hypothyroidism was 9.2% (95%CI: 8.3-10.2), and hypothyroidism was three times higher in women than in men (12.4% versus 3.7%). Hypothyroidism increased with age, reaching a peak of 16.9% in women aged 45 to 64 years. Conclusions: The prevalence of subclinical hypothyroidism in our sample was high and in the upper limits of values found in previous studies. Proper diagnosis and treatment are important because of the risk of progression to hypothyroidism and the association with multiple diseases and other risk factors (AU)

Actual and preferred place of death of home-dwelling patients in four European countries: making sense of quality indicators.

BACKGROUND: Dying at home and dying at the preferred place of death are advocated to be desirable outcomes of palliative care. More insight is needed in their usefulness as quality indicators. Our objective is to describe whether "the percentage of patients dying at home" and "the percentage of patients who died in their place of preference" are feasible and informative quality indicators. METHODS AND FINDINGS: A mortality follow-back study was conducted, based on data recorded by representative GP networks regarding home-dwelling patients who died non-suddenly in Belgium (n = 1036), The Netherlands (n = 512), Italy (n = 1639) or Spain (n = 565). "The percentage of patients dying at home" ranged between 35.3% (Belgium) and 50.6% (The Netherlands) in the four countries, while "the percentage of patients dying at their preferred place of death" ranged between 67.8% (Italy) and 86.0% (Spain). Both indicators were strongly associated with palliative care provision by the GP (odds ratios of 1.55-13.23 and 2.30-6.63, respectively). The quality indicator concerning the preferred place of death offers a broader view than the indicator concerning home deaths, as it takes into account all preferences met in all locations. However, GPs did not know the preferences for place of death in 39.6% (The Netherlands) to 70.3% (Italy), whereas the actual place of death was known in almost all cases. CONCLUSION: GPs know their patients' actual place of death, making the percentage of home deaths a feasible indicator for collection by GPs. However, patients' preferred place of death was often unknown to the GP. We therefore recommend using information from relatives as long as information from GPs on the preferred place of death is lacking. Timely communication about the place where patients want to be cared for at the end of life remains a challenge for GPs.

Patrón epidemiológico de la obesidad en Castilla y León y su relación con otros factores de riesgo de enfermedad cardiovascular / Obesity in Castile and Leon, Spain: epidemiology and association with other cardiovascular risk factors

Estudio transversal de la obesidad en una muestra aleatoria de 4.012 personas de edad >=≥ 15 años en Castilla y León. Se estimó la prevalencia de obesidad (índice de masa corporal ≥ 30) y de obesidad abdominal (cintura > 102cm en varones y > 88cm en mujeres) y se calculó la relación de ambos tipos de obesidad con otros factores de riesgo cardiovascular. La prevalencia de obesidad fue del 21,7% (intervalo de confianza [IC] del 95%, 20,3%-23,2%), mayor en mujeres —23,2% (IC del 95%, 20,9%-25,5%) que en varones —20,4% (IC del 95%, 18%-22,7%)—. La prevalencia de obesidad abdominal fue del 36,7% (IC del 95%, 34,6%-38,9%), mayor también en mujeres —50,1% (IC del 95%, 47%-53,1%)— que en varones —22,8% (IC del 95%, 20,3%-25,2%). Todos los factores de riesgo cardiovascular, excepto el tabaquismo, estuvieron asociados a la obesidad. El riesgo SCORE y Framingham a 10 años fue superior en obesos (AU)

A cross-sectional study of obesity in a random sample of 4012 individuals aged >=15 years in Castile and Leon, Spain, was carried out. The prevalence of obesity (i.e. a bodymass index >=30 kg/m2) and abdominal obesity (i.e. a waist circumference >102 cm in males or >88 cm in females) was determined and associations between both types of obesity and other cardiovascular risk factors were investigated. The overall prevalence of obesity was 21.7% (95% confidence interval [CI], 20.3%-23.2%): it was higher in women, at 23.2% (95% CI, 20.9%-25.5%), than in men, at 20.4% (95% CI, 18.0%-22.7%). The prevalence of abdominal obesity was 36.7% (95% CI, 34.6%-38.9%): again it was higher in women, at 50.1% (95% CI, 47%-53.1%) than inmen, at 22.8% (95% CI, 20.3%-25.2%). Associations were found between obesity and all classic cardiovascular risk factors, except smoking. The 10-year Systematic Coronary Risk Evaluation (SCORE) and Framingham risk scores were higher in obese individuals (AU)

Obesity in Castile and Leon, Spain: epidemiology and association with other cardiovascular risk factors.

A cross-sectional study of obesity in a random sample of 4012 individuals aged ≥ 15 years in Castile and Leon, Spain, was carried out. The prevalence of obesity (i.e. a body mass index ≥ 30 kg/m²) and abdominal obesity (i.e. a waist circumference > 102 cm in males or > 88 cm in females) was determined and associations between both types of obesity and other cardiovascular risk factors were investigated.

ObjetivoLa hipercolesterolemia es uno de los factores de riesgo cardiovascular más sensible a las medidas de prevención y control. Este estudio pretende conocer las características clínicas y epidemiológicas de las personas dislipidémicas en Castilla y León.MétodosSe realizó un muestreo bietápico-estratificado y se obtuvieron datos de 4.013 personas, representativas de la población de 15 o más años de edad en Castilla y León. Se recogieron las variables relacionadas con la enfermedad cardiovascular de la historia clínica, la anamnesis y la exploración. Se determinaron el colesterol total y las distintas fracciones lipídicas (c-HDL, c-LDL y triglicéridos).ResultadosEl colesterol total, el c-HDL, el c-LDL y los triglicéridos aumentan con la edad, y todos excepto el primero presentan diferencias según el sexo. El c-LDL y los triglicéridos están más elevados en los hombres que en las mujeres hasta los 60 años de edad, pero luego el patrón se invierte, mientras que el c-HDL siempre es más alto en las mujeres. El 14,6% de la población tiene un colesterol total ≥250mg/dl y un 56,3% lo tiene ≥200mg/dl. Sólo el 49,6% de las personas con ≥250mg/dl tenían antecedentes en su historia clínica, y únicamente un 15,2% recibían tratamiento. El colesterol total ajustado por la edad se correlacionaba positivamente con todos los demás factores de riesgo cardiovascular. Además, más del 70% de la población presenta al menos un factor de riesgo cardiovascular.ConclusionesDestacan los altos valores de colesterol total y c-LDL, así como los bajos de c-HDL en los hombres, y el infradiagnóstico en las historias clínicas. La asociación de hipercolesterolemia con otros factores de riesgo cardiovascular es similar a la observada en otros estudios (AU)

bjectiveHypercholesterolemia is one of the cardiovascular risk factors more sensitive to preventive and control interventions. This study aims to determine the epidemiological pattern of dyslipidemic people in Castilla y Leon.MethodsA representative stratified two-stage sample of the population resident in Castilla y León (Spain) was obtained. A total of 4,013 people age 15 years and older were interviewed. Cardiovascular disease related variables were gathered from clinical records and medical examination. Total cholesterol, HDL-c, LDL-c, and triglycerides were measured.ResultsTotal cholesterol, HDL-c, LDL-c and triglycerides increase with age and, all but total cholesterol present gender differences. LDL-c and triglycerides are higher in men than in women under the age of 60, and lower from that age on, while HDL-c is always higher in women. Total cholesterol was ≥250mg/dl in 14.6% of the sample and ≥200mg/dl in the 56.3%. Only 49.6% of people with total cholesterol ≥250mg/dl had been diagnosed and only 15.2% were under treatment. Age-adjusted total cholesterol was positively correlated with all cardiovascular risk factors. Furthermore, over 70% of the population presented, at least, one cardiovascular risk factor.ConclusionsThe results above shows high levels of total cholesterol and LDL-c, low levels of HDL-c in males and the under diagnosis in clinical records. The association between hypercholesterolemia and other cardiovascular risk factors is similar to previous studies (AU)

[Prevalence of hypertension in the population of Castile-Leon (Spain)]. / Prevalencia de la hipertensión arterial en la población de Castilla y León.

OBJECTIVE: Cardiovascular disease causes one out of 3 deaths in Spain. Hypertension is involved in ischemic heart disease and in other diseases provoking high morbidity and mortality. The aim of the present study was to describe the prevalence of hypertension and other indicators of this disorder in Castile-Leon in 2004. METHODS: We performed a cross-sectional study in a random sample of 4,012 persons aged 15 years old or above, extracted through a two-stage, stratified design. Systolic and diastolic blood pressure was measured, a history was taken and clinical records were reviewed. A person was considered to be hypertensive when there was known hypertension (hyper-tension was recorded in the clinical records or the person was receiving treatment for hypertension) or when systolic blood pressure was 140 mmHg or more and diastolic blood pressure was 90 mmHg or more. RESULTS: The prevalence of hypertension in the population was 38.7% (95%CI: 36.5-40.9). The prevalence was higher in men (40.4% [95%CI: 37.4-43.4]) than in women (37.4% [95%CI: 34.7-40]). Hypertension was already known in 22.2%, representing 57.4% of all hypertensive individuals. In the remainder of the sample, 44% had prehypertension, 17.5% had stage 1 hypertension and 4% had stage II hypertension, according to the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation and Treatment of High Blood Pressure. CONCLUSIONS: The prevalence of hypertension in the population studied was consistent with that reported in other Spanish studies. A substantial proportion of hypertensive individuals were unaware of their status as such. Equally, a large proportion had prehypertension, which carries a high risk of cardiovascular disease.

Prevalencia de la hipertensión arterial en la población de Castilla y León / Prevalence of hypertension in the population of Castile-Leon [Spain]

Objetivo: Las enfermedades cardiovasculares causan unade cada 3 defunciones en España. La hipertensión arterialestá implicada en la enfermedad isquémica cardíaca y en otras afecciones de alta morbilidad y mortalidad. El objetivo de este trabajo es describir la prevalencia y otros indicadores de la presión arterial en Castilla y León en 2004.Métodos: Estudio transversal en una muestra aleatoria de4.012 personas 15 años de edad extraída de un diseño bietápico y estratificado. Se revisó la historia clínica, se realizó una anamnesis y una exploración de la presión arterial sistólica y diastólica. Se consideró a una persona como hipertensa cuando era hipertensa conocido (en su historia clínica constaba como tal o recibía tratamiento con antihipertensivos) o presentaba una cifra de presión arterial sistólica 140 mmHgo una presión arterial diastólica 90 mmHg.Resultados: La prevalencia de hipertensión arterial en la población fue de 38,7% (intervalo de confianza [IC] del 95%: 36,5-40,9). Los hombres presentaron un mayor porcentaje, 40,4% (IC del 95%: 37,4-43,4), que las mujeres, 37,4% (IC del 95%: 34,7-40). El 22,2% estaba ya diagnosticado, lo que representa el 57,4% de los hipertensos. En el resto de la muestra, el 44%estaba en un estadio prehipertensivo, el 17,5% en estadio I y el 4% en estadio II de la clasificación del séptimo informe del Joint National Committee sobre Prevención, Detección, Evaluación y Tratamiento de la Hipertensión Arterial.Conclusiones: La prevalencia de la hipertensión arterial en la población estudiada es consistente con otros estudios españoles. Una gran proporción de hipertensos no sabe que lo es, y otra gran parte se encuentra en estadios prehipertensivos, con el riesgo cardiovascular que conlleva esta situación

[Design of a population-based study of cardiovascular risk in Castile and Leon [Spain] through primary care teams]. / Diseño de un estudio poblacional del riesgo cardiovascular en Castilla y León a través de los equipos de atención primaria.

We describe the design and the response indicators in a cross sectional study to estimate several factors associated with cardiovascular risk in the population of Castile and Leon. A sample of 4,950 individuals aged 15 years and above was obtained in two stages: in the first stage, 198 primary care physicians were selected and in the second stage a sample of 25 persons from each primary care physician's list was obtained. The response rate was 98% among primary care physicians and 80% among the population. Statistically significant differences were found in age distribution between the frame sample and the definitive sample. After applying design adjustments, only the group aged 35-64 years was significantly overdimensioned. Access to the general population in primary health care is a feasible and effective procedure. A high response rate contributes to the validity of the information.
