Factors associated with childhood obesity in Spain. The OBICE study: a case-control study based on sentinel networks.

OBJECTIVE: To estimate the association strength of dietary behaviour and sedentary habits in relation to childhood obesity in Spain. DESIGN: A matched case-control study was carried out using data collected by sentinel network paediatricians in general practices. SETTING: Five Spanish autonomous communities. SUBJECTS: Cases were 437 children (2-14 years old) with BMI >95th percentile according to Spanish reference tables. Controls were 751 children (2-14 years old; two paired per case) with BMI <84th percentile. Data were collected in two phases: individual (questionnaires filled in by sentinel paediatricians) and family (self-administered questionnaires filled in a family environment). Crude OR and adjusted OR (ORc and adj OR) for the given variables were calculated using a simple and multiple conditional logistic regression analysis. RESULTS: The factors with the greatest effect on obesity were family history of obesity: both parents (adj OR = 11.2), mother but not father (adj OR = 9.1), father but not mother (adj OR = 6.1), siblings (adj OR = 2.7); and eating between meals (adj OR = 2.5) and consumption of sweets and soft drinks >2 times/week (adj OR = 2.0). The highest protection effect was found for five meals per day (adj OR = 0.5), the regular consumption of breakfast (adj OR = 0.5) and for eating fruit for dessert (adj OR = 0.6). Factors related to sedentary habits did not appear as noteworthy. CONCLUSIONS: We have determined the association between certain dietary behaviour and family history with childhood obesity in several Spanish regions.

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)

[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.

Se describe el diseño y los indicadores de respuesta de un estudio transversal para estimar diferentes parámetros del riesgo cardiovascular en la población de Castilla y León. Se obtuvo una muestra de 4.950 personas de 15 y más años de edad en dos etapas: en la primera etapa se eligieron 198 médicos de atención primaria, y en la segunda se seleccionó una muestra de 25 personas del cupo de cada médico. Las tasas de respuesta de los médicos alcanzaron el 98%, y las de la población superaron el 80%. Se encontraron diferencias estadísticamente significativas en la distribución por edad del marco muestral y la muestra definitiva. Después de realizar las ponderaciones derivadas del diseño, sólo el grupo de edad de 35-64 años se encuentra significativamente sobredimensionado. El acceso a la población general en atención primaria es un procedimiento factible y eficaz. La alta tasa de respuesta contribuye a la validez de la información

Riesgo de enfermedad isquémica del corazón en el área de salud de Valladolid Oeste / Isquemic Heart Disease Risk in the West Valladolid Health Area

Introducción y objetivos. Las enfermedades del aparato cardiovascular, especialmente la enfermedad isquémica del corazón, presentan una elevada morbilidad y mortalidad en nuestro país. El objeto del presente trabajo es estimar el riesgo coronario medio de los residentes adscritos al Área de Salud de Valladolid oeste. Métodos. Estudio transversal en una muestra aleatoria de 369 individuos entre 35 y 64 años de la población general, de la presión arterial sistólica, las concentraciones de colesterolemia total y el consumo de cigarrillos. Con estos tres factores, más el sexo y la edad, se calculó el riesgo coronario individual siguiendo el método empleado en el Dundee Coronary Risk-Disk. Resultados. El riesgo coronario medio del área estudiada, es decir, la probabilidad de que una persona presente un evento coronario en los próximos cinco años de su vida, se estimó en 5,22 por ciento (IC del 95 por ciento, 4,75-5,69 por ciento), mayor en los varones (5,66 por ciento; IC del 95 por ciento, 4,95-6,36 por ciento) que en las mujeres (4,63 por ciento; IC 95 por ciento, 4,15-5,11 por ciento). Existe una tendencia a la disminución del riesgo coronario a medida que aumenta la edad. Conclusiones. El método empleado es relativamente fácil de obtener para estudios comunitarios y sencillo de aplicar al riesgo individual. El riesgo coronario de una persona de la población estudiada se encuentra en niveles similares a los recogidos en otros trabajos de nuestro entorno. Los niveles poblacionales de los factores de riesgo coronario aislados no permiten establecer la mejor opción en el control del riesgo coronario, y sólo un enfoque multicausal permitirá valorar las intervenciones más eficaces en cada grupo de edad y sexo (AU)
