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/m 2 ) 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 in men, 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.

ResumenObjetivoLa 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.AbstractObjectiveHypercholesterolemia 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.

Se describe el diseno y los indicadores de respuesta de un estudio transversal para estimar diferentes parametros del riesgo cardiovascular en la poblacion de Castilla y Leon. Se obtuvo una muestra de 4.950 personas de 15 y mas anos de edad en dos etapas: en la primera etapa se eligieron 198 medicos de atencion primaria, y en la segunda se selecciono una muestra de 25 personas del cupo de cada medico. Las tasas de respuesta de los medicos alcanzaron el 98%, y las de la poblacion superaron el 80%. Se encontraron diferencias estadisticamente significativas en la distribucion por edad del marco muestral y la muestra definitiva. Despues de realizar las ponderaciones derivadas del diseno, solo el grupo de edad de 35-64 anos se encuentra significativamente sobredimensionado. El acceso a la poblacion general en atencion primaria es un procedimiento factible y eficaz. La alta tasa de respuesta contribuye a la validez de la informacion.

Resumen El objetivo de este trabajo es describir el procedimiento seguido para el diseno de normas tecnicas de tratamiento (NTT) para su inclusion en la cartera de servicios de atencion primaria, presentar la redaccion de las 4 normas incluidas y los resultados del estudio de concordancia en su evaluacion. Se recogio el fundamento cientifico tecnico del contenido de la norma en un informe tecnico que incluyo un repertorio bibliografico y una copia de los principales articulos. La propuesta inicial de las normas se publico en un numero especial del boletin Ojo de Markov , dirigido a profesionales sanitarios. Se promovio un debate entre los profesionales, tanto acerca del contenido como de la pertinencia de este tipo de normas. Las opiniones y sugerencias se recogieron mediante una encuesta. Se realizo un estudio para valorar la concordancia en la evaluacion de las normas entre 3 observadores independientes, en una muestra de 300 historias clinicas. Un grupo de expertos valoro el respaldo cientifico, las sugerencias de los profesionales y redacto la version final de las normas. La propuesta de inclusion de NTT en la cartera de servicios de atencion primaria como herramienta de calidad y de apoyo a las decisiones clinicas se recibio por los profesionales con distinto nivel de acuerdo. El cuerpo de la norma define el tratamiento de eleccion, y como aclaraciones a la evaluacion se incluyen otras variantes clinicas admitidas en los consensos. Las NTT propuestas han mostrado buena concordancia entre evaluadores.

OBJECTIVES: To find out the proportion of primary healthcare consultations that could be attended by another professional other than the doctor. DESIGN: multicentre cross-sectional study. LOCATION: Primary healthcare, west-gipuzkoa region, with 17 health centres taking part. PARTICIPANTS: Reasons for consultation dealt with by 38 doctors over 5 days. MAIN MEASUREMENTS: Age, sex, frequency, category, initiative, reason for consultation and ideal level of healthcare. RESULTS: A total of 4,377 patients who generated 5,592 consultations were included. The average frequency was 10 visits/year. The large majority (93.1%) of consultations took place in the centre, 5.4% by telephone and 1.5% were home visits. A total of 74.4% of the consultations were requested, 17.2% arranged by the doctor, 6.4% arranged by protocol, 2% at the request of other professionals, and 8% were urgent. The reasons were; 71.5% (95% CI: 69.8-73.2) were medical clinical, 7.2% (6.2-8.2) minor symptoms, 18.4% (17.1-19.5) bureaucratic, and 2.9% (2.3-3.3) for information. The consultations for medical reasons accounted for 80.5% (79.3-81.7) and 19.5% (18.3-20.7) were for non-medical reasons. Non-medical reasons made up 29.3% of the telephone consultations, 20.2% of the consultations in the centre, and 2.4% of the home visits, as well as 16.7% of the urgent consultations. The ideal level of healthcare was considered to be doctor 80.7%, 13.2% nursing and 2.8% administrative. In the consultations for minor symptoms, nursing was considered the ideal level in 65.3% of cases. CONCLUSIONS: One out of every 5 consultations could be dealt with by a professional other than the doctor, which in 5 hours of consultations would allow 1 hour to be gained which could be used for other activities.

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.

ResumenObjetivoLas enfermedades cardiovasculares causan una de cada 3 defunciones en España. La hipertensión arterial está 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.MétodosEstudio transversal en una muestra aleatoria de 4.012 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 ≥140mmHg o una presión arterial diastólica ≥90mmHg.ResultadosLa 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.ConclusionesLa 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.AbstractObjectiveCardiovascular 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.MethodsWe 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 (hypertension was recorded in the clinical records or the person was receiving treatment for hypertension) or when systolic blood pressure was 140mmHg or more and diastolic blood pressure was 90mmHg or more.ResultsThe 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.ConclusionsThe 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.
