Percepción de los pediatras de Atención Primaria de su relación con la Pediatría Hospitalaria / Perception of the Primary Care pediatricians of their relationship with Hospital Pediatrics

Objetivo. El objetivo de este trabajo es conocer la percepción que tienen los pediatras de Atención Primaria (PAP) de Castilla y León de su relación con la Pediatría Hospitalaria. Población y métodos. Se realizó una encuesta entre los pediatras de Atención Primaria para conocer la relación entre niveles asistenciales en las 11 áreas sanitarias de la Comunidad. El cuestionario es anónimo y consta de 16 preguntas en dos bloques: 9 sobre “cómo es/cómo percibimos la relación entre los PAP y el hospital” (bloque 1) y 7 sobre “qué cosas son importantes para los PAP/qué se pide al hospital” (bloque 2). Se puntúa con una escala Likert de 1 (nada) a 5 (máximo). Resultados. Respondieron 134 pediatras (84% mujeres). El 64% tiene 15 años de experiencia en PAP. El 77% trabajan como pediatras de equipo, y el 64% en centros urbanos. El 43% tiene cupos de 800-999 pacientes. El 24% son tutores de apoyo MIR y el 24% colabora en la formación de estudiantes de Medicina. En el primer bloque de preguntas se observan medianas entre 2 y 4 de puntuación Likert, y en el segundo bloque los valores son más elevados (mediana 4). Encontramos diferencias significativas al comparar las respuestas por áreas sanitarias, en todas las preguntas del primer bloque y en la mayoría del segundo. Conclusión. La relación entre niveles es aceptable en su conjunto, con importantes diferencias entre áreas sanitarias (AU)

Objective. To know the perception that Primary Care pediatricians (PCP) of Castilla y Leon have about their relationship with hospital pediatricians. Population and methods. A survey was conducted among PCP to find out the relationship between healthcare levels in the 11 health areas of the Community. The questionnaire is anonymous and consists of 16 questions (two blocks): 9 about “how is/how we perceive the relationship between the PCP and the hospital” (first block) and 7 about “what is important for the PCP/what is asked to the hospital” (second block). It is scored on a Likert scale from 1 (not at all) to 5 (maximum). Results. 134 pediatricians answer (84% women). 64% have 15 years of experience as PCP. 77% work as team pediatrician, and 64% in urban settings. 43% attends 800-999 patients. 24% are support tutors and 24% are trainers of medical students. Medians between 2 and 4 of Likert scores are observed in the first block of questions, and values are higher (4) in the second one. We find significant differences when making comparisons by Health Areas in all the questions in the first block and in most of them in the second. Conclusión. The relationship between healthcare levels is acceptable as a whole with important differences among health areas (AU)

Quality of life in caregivers of children with asthma: Validity and reliability of the IFABI-R questionnaire

BACKGROUND: Parents'/caregivers' quality of life is an important aspect to consider when handling paediatric asthma, but there is a paucity of valid and reliable instruments to measure it. The Family Impact of Childhood Bronchial Asthma (IFABI-R) is a recently developed questionnaire to facilitate the assessment of asthma-related parents'/caregivers' quality of life. This study researches the psychometric properties of IFABI-R. METHODS: Parents/main caregivers of 462 children between 4 and 14 years of age with active asthma were included in the sample. IFABI-R was administered on two different occasions and a number of other variables related to the parents'/caregivers' quality of life were measured: child's asthma control, family functioning, and parents'/caregivers' perception of asthma symptoms in the child. IFABI-R evaluative and discriminative properties were analysed, and the minimal important change in the IFABI-R score was identified. RESULTS: IFABI-R showed high internal consistency (Cronbach's alpha = 0.941), cross-sectional construct validity (correlation with the degree of child's asthma control, family functioning and parent/caregiver perception of the child's asthma symptoms), longitudinal construct validity (correlation of changes in the IFABI-R with changes in asthma control and changes in the perception of symptoms), sensitivity to change and test-retest reliability. An absolute change of 0.3 units in IFABI-R related to a minimal significant change in the parents'/caregivers' quality of life. CONCLUSIONS: IFABI-R is a reliable and valid instrument to study the quality of life of parents/caregivers of children with asthma

[Paediatric prescribing of anti-asthmatics in primary care in Castilla-León. Geographical variability]. / Prescripción pediátrica de fármacos antiasmáticos en atención primaria en Castilla y León. Variabilidad geográfica.

INTRODUCTION AND OBJECTIVES: Asthma is one of the most prevalent chronic diseases with effective treatment in paediatrics. The aim of this study is to describe the paediatric prescribing of anti-asthmatics in Castilla-León, analyzing its geographic variability and temporal evolution. MATERIAL AND METHODS: An analysis was made of prescriptions dispensed in pharmacies of R03 therapeutic subgroup (anti-asthmatic agents), and the active ingredients mepyramine and ketotifen, prescribed in children less than 14 years of age in the Castilla-León health service from 2005 to 2010 in Primary Care. Data is presented in prescribed daily doses per thousand inhabitants per day (PDHD) for each active ingredient being calculated raw rates and age-adjusted to the variables health area, type of health zone and year of study. RESULTS: A total of 462,354 prescriptions of anti-asthmatic agents were dispensed to a population of 1,580,229 persons/year. There was wide variation between areas in the type and intensity of anti-asthmatic agents used, partly explained by differences in the prevalence of asthma. Montelukast predominated as controller drug in most of them (PDHD 3.1 to 7.7), being similar the consumption intensity in the three types of health zones (PDHD 4.7 to 4.8). The annual variability was low. CONCLUSIONS: The study describes the paediatric prescribing pattern of anti-asthmatic agents in Castilla-León between 2005-2010. It shows wide geographical variation, as well as inadequacies regarding current recommendations of asthma treatment.

Prescripción off-label de antiasmáticos en Atención Primaria / Off-label prescription of anti-asthmatic agents in Primary Care

Introducción y objetivos: se denomina prescripción off-label a la realizada fuera de las condiciones autorizadas en la ficha técnica de un medicamento. En Atención Primaria se publican cifras globales de prescripción off-label en diferentes países del 3-67%. El objetivo del estudio ha sido conocer la intensidad de este tipo de prescripción en el caso de los antiasmáticos en un periodo reciente, en Castilla-León (España). Métodos: se analizaron las prescripciones correspondientes al subgrupo terapéutico R03 (medicamentos para enfermedades obstructivas respiratorias) realizadas a menores de 14 años entre 2005-2010 en el sistema público de salud autonómico. La información sobre el uso off-label se presenta en número de prescripciones consumidas de antiasmáticos a dosis y/o edades no recomendadas en su ficha técnica. Resultados: se realizaron 394876 prescripciones de antiasmáticos a una población expuesta de 1 580229 personas/año. Los menores de cuatro años fueron los que más antiasmáticos recibieron. La máxima prescripción de broncodilatadores ocurrió en menores de dos años, la de montelukast y corticoides inhalados monofármaco al año de edad. El 46% de las prescripciones de salbutamol sistémico y el 15,9% de las de la terapia de mantenimiento se prescribieron off-label. Conclusiones: el estudio muestra un uso importante de antiasmáticos a edades muy tempranas en las que es difícil hacer el diagnóstico de asma y un consumo notable de fármacos controladores a dosis y/o edades no autorizadas. La prescripción off-label no presupone una prescripción inadecuada, pero debería tener un beneficio real para el paciente y estar apoyada por avales científicos que justifiquen su uso (AU)

Introduction and objectives: off-label prescribing is when performed outside of the official information of the product. Overall figures of off-label prescribing in primary care in different countries are 3-67%. The aim of the study was to determine the intensity of this type of prescription in anti-asthmatic agents in a recent period of time, in Castilla y León. Methods: the requirements for the therapeutic subgroup R03 (anti-asthmatic agents) prescribed in children less than 14 years of age in the Castilla-León health service from 2005 to 2010 were analyzed. Information on off-label prescribing is shown in number of anti-asthmatic prescriptions consumed at doses and/or at ages not recommended in its technical specifications. Results: a total of 394 876 prescriptions for anti-asthmatic agents were performed to an exposed population of 1 580 229 person-years. Children under four years received the highest levels of anti-asthmatic agents. The maximum prescription of bronchodilators occurred in children under 2 years, and of montelukast and single inhaled corticosteroids at one year of age. 46% of prescriptions of systemic salbutamol and 15.9% of maintenance therapy prescriptions were made in an off-label manner. Conclusions: the study shows an important and very early use of anti-asthmatic agents at ages where it is difficult to make a diagnosis of asthma and also a remarkable consumption of controller therapy at not authorized dose and/or ages. Off-label prescription do not presuppose inappropriate prescription but it should have a real benefit to the patient and be supported by scientific guarantees to justify its use (AU)

Prescripción pediátrica de fármacos antiasmáticos en atención primaria en Castilla y León. Variabilidad geográfica / Paediatric prescribing of anti-asthmatics in primary care in Castilla-León. Geographical variability

INTRODUCCIÓN Y OBJETIVOS: El asma es una de las enfermedades crónicas con tratamiento eficaz más prevalentes en pediatría. El objetivo de este trabajo es describir la prescripción pediátrica de antiasmáticos en Castilla y León, analizando su variabilidad geográfica y su evolución temporal. MATERIAL Y MÉTODOS: Se estudiaron las prescripciones dispensadas en farmacias del subgrupo terapéutico R03 (medicamentos antiasmáticos) y de los principios activos mepiramina y ketotifeno, realizadas a menores de 14 años en atención primaria en el Sistema Nacional de Salud entre 2005 y 2010. Los datos se presentan en dosis diarias prescritas por 1.000 habitantes/día (PDHD) para cada principio activo, calculándose tasas crudas y ajustadas por edad para las variables área sanitaria, tipo de zona de salud y año del estudio. RESULTADOS: Se realizaron 462.354 prescripciones de antiasmáticos a una población expuesta de 1.580.229 personas-año. Hubo amplia variabilidad entre las áreas en el tipo e intensidad de los antiasmáticos utilizados, en parte explicada por diferencias en su prevalencia de asma. Montelukast predominó como fármaco controlador en la mayoría de ellas (3,1-7,7 PDHD), siendo su intensidad de consumo similar en los 3 tipos de zonas de salud (4,7-4,8 PDHD). La variabilidad anual fue escasa. CONCLUSIONES: El estudio describe el patrón pediátrico de prescripción de antiasmáticos en Castilla y León entre 2005 y 2010. Muestra gran variabilidad geográfica, así como inadecuaciones respecto a las recomendaciones actuales de tratamiento del asma

Anti-asthmatic prescription variability in children according to age

INTRODUCTION: There is little research in the Spanish paediatric population about the consumption of anti-asthmatic agents. The aim of this study was to describe the current pattern of anti-asthmatic drug prescription in the paediatric population from a region of Spain, using the prescribed daily dose as a unit of measurement. METHODS: We analysed the requirements of R03 therapeutic subgroup (anti-asthmatic agents) in children less than 14 years of age in the Public Health System of Castilla y León from 2005 to 2010. Consumption data are presented in prescribed daily doses per thousand inhabitants per day (PDHD) and compared with defined daily doses per thousand inhabitants per day (DHD). RESULTS: 394 876 prescriptions of anti-asthmatics were given to a population of 1 580 229 persons/year. Bronchodilators, leukotriene receptor antagonists, single inhaled corticosteroids (ICS) and long-acting β2-adrenergics associated with inhaled corticosteroids were the most commonly prescribed drugs: 7.5, 5.2, 4.9 and 2.2 PDHD, respectively. The maximum prescription of bronchodilators (15.9 PDHD/9.8 DHD) occurred in children under 12 months, with montelukast (8.9 PDHD/3.6 DHD) and single inhaled corticosteroids (7.9 PDHD/2.9 DHD) at one year of age. CONCLUSIONS: Between 2005 and 2010, children under four years received a high prescription of anti-asthmatic drugs. The use of maintenance therapy was poorly aligned with the recommendations of asthma guidelines. The PDHD was more accurate for measuring consumption than DHD, especially in younger children

Opiniones y expectativas de los padres respecto a las infecciones respiratorias agudas de lactantes y pre-escolares. Influencia en la disposición a consultar / Opinions and expectations of the parents regarding acute respiratory infections of infants and pre-school children. Influence on the facility to consult

Objetivos: Describir las opiniones y expectativas de los padres relacionadas con la disposición a consultar por infecciones respiratorias agudas de lactantes y pre-escolares. Métodos: Estudio transversal con muestra oportunista de padres de niños menores de cinco años. Se diseñó un cuestionario que exploraba las opiniones acerca de la frecuencia, sintomatología, gravedad y tratamiento de las infecciones respiratorias agudas, así como las expectativas respecto a la atención médica por esas enfermedades, y la disposición de los padres a consultar con el médico en distintas situaciones. Se realizó un análisis multivariante exploratorio para identificar las variables más relacionadas con la disposición a consultar. Resultados: Se recogieron 317 encuestas. El 54,6% de los niños del estudio eran varones, la edad mediana (amplitud intercuartil) era de 2,0 (0,6-3,3 años) y un 5,7% había estado alguna vez hospitalizado por enfermedades respiratorias. El modelo multivariante encontró siete variables asociadas a la disposición a consultar, agrupables en tres dominios: 1) percepción de vulnerabilidad del niño (menor edad y antecedentes de hospitalización); 2) percepción de una amenaza (creencia en la gravedad de las infecciones respiratorias y expectativa de que el médico le indique si es grave); y 3) percepción de eficacia del tratamiento farmacológico (creer en la eficacia de medicinas para tos y mocos, creer en la eficacia de antibióticos, y esperar una prescripción en la consulta). Conclusiones: La disposición a consultar por las infecciones respiratorias agudas de lactantes y pre-escolares se asocia a un conjunto definido de opiniones y expectativas de los padres

Aim: Describe the parents' beliefs and expectations related to the willingness to consult for acute respiratory infections in infants and preschool children. Methods: Cross-sectional study of an opportunistic sample of parents of children of less than five years. A questionnaire was designed to explore beliefs about frequency, symptoms, severity and treatment of acute respiratory infections, expectations on health care from doctors, and willingness to consult in certain circumstances. In an exploratory multivariate analysis, the main variables related to willingness to consult were identified. Results:. There were 317 questionnaires collected; 54.6 percent of children were male, their median age (interquartile range) was 2.0 years (0.6-3.3 years), and 5.7% had been hospitalized because respiratory diseases. The multivariate model found seven variables related to the willingness to consult, that could be clustered in three domains: 1) perception of vulnerability in children (lower age and previous hospitalization); 2) perception of threat (beliefs about severity of respiratory diseases and expectations that the doctor says whether the disease is severe); and 3) perception of efficacy of drugs (beliefs about efficacy of symptomatic drugs and of antibiotics, and expectations of being prescribed a drug). Conclusions:. The willingness to consult for acute respiratory infections in infants and preschool children is related to a definite set parents' beliefs and expectations

Prescripción de fármacos anticatarrales de uso sistémico a niños de 0-13 años. Un problema no resuelto / Prescription of systemic cold and cough drugs to children 0-13 years old. An unresolved problem

Introducción y objetivos: La infección de las vías respiratorias superiores es el motivo de consulta pediátrica más frecuente, generando un elevado volumen de prescripción de fármacos con desfavorable relación riesgo-beneficio. El objetivo del estudio es describir la prescripción de anticatarrales por vía sistémica a menores de 14 años en Castilla y León y analizar su variabilidad. Población y métodos: Se contabilizaron las prescripciones de los subgrupos R05 (antitusivos y mucolíticos) y R01B (simpaticomiméticos) realizadas a menores de 14 años en el sistema público de salud entre 2005-2010. Se analizaron las prescripciones como tasas crudas y ajustadas por edad, y se realizó un análisis multivariante (regresión de Poisson) de la variabilidad relacionada con el área sanitaria, el ámbito urbano/rural, la edad y el año de prescripción. Resultados: Hubo 806.785 prescripciones de anticatarrales sistémicos realizadas a una población expuesta de 1.580.229 personas-año. Las tasas de prescripción (por 100 personas-año) fueron de 20,7 (antitusivos), 7,0 (simpaticomiméticos) y 23,4 (mucolíticos). Las tasas eran mayores en los niños menores de 4 años. La prescripción máxima de mucolíticos y simpaticomiméticos ocurrió a la edad de 1 año (tasas de 41,9 y 18,7) y la de antitusivos a los 3 años (35,7). El análisis multivariante demostró una mayor prescripción en el medio rural y diferencias notables entre áreas. El número de prescripciones disminuyó entre 2005 y 2010, pero no hubo una tendencia estable en esa reducción. Conclusiones: Entre 2005 y 2010 la prescripción de anticatarrales sistémicos fue alta, alejada de las recomendaciones internacionales de tratamiento y con una marcada variabilidad geográfica(AU)

Introduction and objectives: Upper respiratory tract infections are the most common cause of paediatric consultation, generating a high volume of prescriptions of drugs with unfavourable risk-benefit ratio. The aim of this study is to describe the prescription of systemic cough and cold medicines to children under 14 years of age in Castilla y León and analyse its variability. Population and methods: A count was made of the prescriptions for the R05 therapeutic subgroup (antitussives and mucolytics) and the R01B pharmacological therapeutic subgroup (nasal decongestants for systemic use), prescribed for children under the age of 14 in the Public Health System between 2005-2010. The number of prescriptions was analysed as crude and age-adjusted rates, as well as a a multivariate analysis (Poisson regression) of the variability associated with health area, the urban/rural environment, age, and year of prescription. Results: There were 806,785 prescriptions for systemic cough and cold drugs given to an exposed population of 1,580,229 person-years. Prescription rates (per 100 person-years) were 20.7 (antitussives), 7.0 (sympathomimetic) and 23.4 (mucolytics). These drugs were employed more often in children <4 years. The prescription of mucolytics and sympathomimetics was highest at age of 1 year (rates=41.9 and 18.7, respectively) and of antitussives at 3 years (35.7). Multivariate analysis showed that in rural areas the prescription was higher than in urban areas, and that there were also significant differences between health areas. Conclusions: Between 2005 and 2010 there was a high prescription of systemic cough and cold medicines, especially in children under 2 years old, and often outside the recommended conditions of use, and there was a high geographic variabilty(AU)

Determinantes del nivel de actividad física en escolares y adolescentes: estudio OPACA / Determining factors of physical activity level in school children and adolescents: The OPACA study

Introducción: La actividad física es uno de los principales condicionantes de la salud humana. Este estudio intenta medir el nivel de actividad física en niños e investigar qué factores la determinan. Población y métodos: Población de 11 y 14 años del área centro-sur de Palencia, en la que se determina el nivel de actividad física mediante diario de tres días y se obtienen medidas antropométricas y socioeconómicas. Se analizan las variables: gasto energético por actividad física ajustado por masa magra (AEE/FFM), nivel de actividad física (PAL), y categoría de actividad física (activo/inactivo). Resultados: Se incluyeron 179 niños, y el 71,5% eran activos o muy activos. La actividad física de los varones era más alta en las tres variables analizadas, y la actividad también era mayor en verano. La actividad física se reducía de los 11 a los 14 años, y era menor durante los fines de semana. No se encontraron diferencias relacionadas con la obesidad o el sobrepeso, ni con la grasa corporal. Los niños más activos tenían menor tensión arterial. El nivel de actividad física se relacionó directamente con las horas semanales de actividades deportivas, e inversamente con el tiempo pasado en actividades sedentarias. En análisis multivariante también se encontró un mayor nivel de actividad en niños de familias con menor nivel educativo, no relacionado con la práctica deportiva. Conclusiones: La actividad física en la población estudiada es aceptable, pero hay diferencias entre sexos y tiende a disminuir durante la adolescencia (AU)

Introduction: Physical activity is a key factor for human health. This study attempts to measure the level of physical activity in children and to find out what are the factors that determine it. Method: In a sample of the 11 and 14 year-old population of the centre-south area of Palencia, physical activity was measured using a three day diary, and anthropometric and socioeconomic variables were collected. Three variables were analysed: fat-free mass adjusted activity energy expenditure (AEE/FFM), physical activity level (PAL), and categorical physical activity (active/inactive). Results: A total of 179 children were included, of whom 71.5% were active or very active. Males were more active than females, and activity was also higher in summer. Physical activity declined between 11 and 14 years, and was lower during the weekends than in working days. There were no differences related to obesity, overweight or percent body fat. More active children had lower blood pressure. Physical activity was directly related to weekly hours spent in sport activities, and inversely related to time spent on sedentary activities. Multivariate analysis showed that children from families with low educational levels had a higher activity level not related to sport activities. Conclusions: The level of physical activity in this population is acceptable, although there are sex differences and there is a declining trend through the adolescence (AU)

Desigualdades sociales en la prevalencia de sobrepeso y obesidad en adolescentes / Social disparities in the prevalence of overweight and obesity in adolescents

Introducción: Muchos factores sociales influyen en el riesgo de sobrepeso/obesidad en niños y adolescentes, obstaculizando su abordaje por los profesionales sanitarios. Este estudio intenta definir el peso de algunos factores sociales y familiares en el riesgo de obesidad en niños y adolescentes. Métodos: Muestra poblacional de niños de 11 y 14 años reclutados en tres centros de salud en Palencia. Variables recogidas: somatometría, peso neonatal, actividad deportiva extraescolar, horas diarias viendo televisión (TV) y datos de los padres (somatometría, nivel de estudios y ocupación laboral). Se construyeron modelos multivariantes, ajustados por centro de estudio, para analizar la influencia de esas variables sobre el riesgo de sobrepeso/obesidad. Resultados: Se incluyeron 322 niños. La prevalencia de obesidad fue 5,6% y de cualquier grado de sobrepeso 28,9%. El sobrepeso no estuvo relacionado con nivel educativo ni ocupación, pero sí con sexo varón (OR 2,07; IC95% 1,12–3,83), sobrepeso del padre (OR 2,18; IC95% 1,14–4,15) o la madre (OR 2,17; IC95% 1,18–3,98), y ver TV ≥2h/día (OR 2,72; IC96% 1,43–5,19), y fue menos frecuente a los 14 que a los 11 años (OR 0,42; IC95% 0,23–0,78). La obesidad solo se asoció con bajo nivel de estudios (OR 19,45; IC95% 1,95–193,82). Conclusiones: El sobrepeso, en general, está relacionado con factores de riesgo genético-ambientales y estilos de vida, propios de la sociedad actual y que afectan a todo el espectro social. Pero la obesidad está muy estrechamente vinculada a un nivel educativo familiar bajo y continúa siendo un marcador de desigualdad en salud (AU)

Introduction: Many social factors have a role in determining the risk of overweight/obesity in children and adolescents, and are the main barriers in their management. This study tries to define the effect that some familial and social factors have on the risk of overweight/obesity in children and adolescents. Method: Population sample of 11- and 14-years old children recruited in three Primary Care Centres in Palencia. Their weight, height and skin folds were measured, and information gathered about sport activities, TV watching, and parental data (weight, height, educational status and occupation). Multivariate models were used to analyse the effect of these variables on the weight status and on the body fat. Results: Three hundred and twenty-two children were included. Prevalence of obesity was 5.6% and that of any degree of overweight was 28.9%. Overweight was not related to educational status or occupation, but it was more often found in males (OR 2.07; 95% CI; 1.12–3.83), in children whose father (OR 2.18; 95% CI; 1.14–4.15) or mother (OR 2.17; 95% CI; 1.18–3.98) were overweight, and in those who spent ≥2h daily watching TV (OR 2.72; 95% CI; 1.43–5.19), and it was less frequent in 14 than in 11-year old children (OR 0.42; 95% CI; 0.23–0.78). Obesity was only related to a low educational level (OR 19.45; 95% CI; 1.95–193.82). Conclusions: Overweight is related with genetic-environmental factors and the modern society way of life, and occurs across the whole social spectrum. But obesity is strongly related to a low educational status of the family, and it still is a marker for health disparities (AU)

Mochilas escolares y dolor de espalda en la población infantil / School backpacks and back pain in child population

Introducción: el peso de las mochilas preocupa por el esfuerzo físico que realizan los niños y su relación con problemas de espalda. El objetivo es conocer los hábitos del uso de mochilas y su relación con el dolor de espalda en población escolar. Material y métodos: estudio observacional en 4 consultas pediátricas. Se analizan variables demográficas, antropométricas y se administra un cuestionario. Resultados: son 159 niños, 80 varones y 79 mujeres, de 11 y 14 años, que cursan 5º de Educación Primaria (EP) y 2º de Educación Secundaria (ESO). El 69% acude al colegio andando, el 80% lleva la mochila en ambos hombros, el 59% se cansa y el 62,3% refiere dolor de espalda. La puntuación del dolor es 5 (escala 0-10). La mochila pesa 6,3 ± 2 kg. El peso relativo (porcentaje de peso en relación al peso del niño) es 13,4% ± 5,5 y no difiere entre sexos, medio urbano o rural, pero sí entre grupos de edad (15,5% en EP, 11,6% en ESO, p < 0,001) y centro (público: 14,3%; concertado: 12,3%; p = 0,02). No encontramos diferencias en el peso con o sin dolor (13,8% versus 12,7%; p = 0,19) ni en la presencia de dolor por sexo o edad. No se encuentra asociación entre dolor y horas de tele/ videojuegos pero sí entre dolor y horas de deporte extraescolar (más horas, menos dolor: OR [odds ratio]: 0,23; IC [intervalo de confianza] 95%: 0,08-0,7). Existe diferencia en la puntuación de síntomas psicosomáticos, mayor en los que sufren dolor (OR 1,37; IC 95%: 1,2-1,6). Conclusiones: el peso de las mochilas es el 13,4% ± 5,5 del peso del niño. Aunque no encontramos asociación entre dolor y peso, este influye en la sensación de malestar en la infancia y debe considerarse un problema de salud(AU)

Diferencias entre el manejo habitual de la infección urinaria en Atención Primaria y las recomendaciones actuales / No disponible

Objetivo: evaluar las actitudes de los adolescentes ante las drogas y la magnitud de su consumo, tanto de legales como de ilegales, por medio de una encuesta, con el fin de deducir las necesidades formativas y elaborar posteriormente un programa preventivo y de promoción de la salud. Material y métodos: encuesta anónima a los estudiantes de dos centros de educación secundaria, un instituto y un centro de formación profesional situados en el área de salud. Se han realizado 445 encuestas a adolescentes de entre 14 y 18 años (edad media 16,04), excluyéndose 13 por datos insuficientes. Resultados: 184 adolescentes (45%) afirman que han fumado tabaco en los últimos 6 meses, 217 (64%) que han consumido alcohol, 111 (44%) han tomado cannabis, 21 (9%) cocaína y un 7% pastillas (éxtasis-anfetaminas). Un 22% de los adolescentes entre 14 y 18 años no había tomado ninguna de las sustancias mencionadas. En cuanto a la consideración como droga de los diversos productos, todos estuvieron de acuerdo en que la heroína lo era y en porcentajes decrecientes opinaban que eran drogas la cocaína (98%), las pastillas (98%), el hachís (96%), el tabaco (80%) y en último lugar el alcohol (64%). Conclusiones: el alcohol es la droga más consumida por estos adolescentes y la que menor consideración de droga tiene entre ellos. Lo mismo sucede, en menor medida, con el tabaco y el hachís. Es preciso aportar a los adolescentes una información veraz sobre las consecuencias y peligros de las denominadas "drogas legales" (AU)

Objective: to evaluate the attitude of the adolescents and the magnitude of the drug consumption, both legal and illegal, through a survey, in order to infer the formative needs and to work on a preventive and health’s promotion program. Subject and methods: an anonymous survey to the students of two Secondary Schools of the health area. Four hundred and forty-five surveys have been made to adolescents between 14 y 18 (mean: 16.04), 13 were excluded because of insufficient information. Results: one hundred and eighty-four adolescents (45%) say that they have smoked in the last 6 months, 217 have drunk alcohol (64%), 111 have taken cannabis (44%), 21 cocaine (9%) and pills (MDMA, amphetamines) (7%). Twenty-two percent of the adolescents have no taken any of these substances. As for the consideration of those products as drugs, they all agree that the heroin is a drug, but that was not so clear in the case of the rest, with the next percentages: cocaine (98%), pills (98%), hashish (96%), tobacco (80%) and finally alcohol (64%). Conclusions: alcohol is the most consumed drug by these adolescents and it is what they consider the least as a drug. The same happens, in a lesser extent, with tobacco and hashish. It’s necessary to give the adolescents true information about the danger and consequences of the "legal drugs" (AU)

Diferencias entre el manejo habitual de la infección urinaria en Atención Primaria y las recomendaciones actuales / No disponible

Objetivos: conocer la incidencia de infección urinaria (ITU) en los lactantes de Venta de Baños (Palencia). Estimar la importancia de la patología asociada a estas infecciones. Evaluar la adecuación de las pruebas de imagen a las propuestas en la Guía NICE sobre ITU en la infancia. Material y métodos: estudio retrospectivo en el que se revisan las historias clínicas de los niños nacidos en Venta de Baños entre 2001 y 2006, recopila información sobre solicitud de urocultivos en los primeros dos años, motivo de la petición, resultado, tratamiento y seguimiento. Se compara los estudios de imagen realizados en esta población con los que propone la Guía NICE de agosto 2007. Resultados: se analizaron 293 historias clínicas. La incidencia acumulada de ITU fue del 7,5%. Se hizo ecografía renal al 90%, CUMS (cistoureterografía miccional seriada) al 66% y DMSA (gammagrafía cortical renal con ácido dimercaptosuccínico) al 18%. El 10% de varones y el 25% de las niñas con ITU presentaron reflujo vesicoureteral (RVU), todos de grado II. Siguiendo las recomendaciones de la Guía NICE, el 75% de los CUMS no estaban indicados y no se realizó DMSA tardío al 76% de los casos en los que hubiera estado indicado. Conclusiones: nuestra incidencia acumulada de ITU es algo mayor que la de otras series. Nuestros lactantes presentaron ITU no complicadas y RVU de bajo grado. Hemos realizado pocas DMSA y muchas CUMS según las recomendaciones actuales. Planteamos un seguimiento menos agresivo de la ITU en el niño en nuestra área sanitaria (AU)

Objectives: to determine the incidence of urinary tract infection (UTI) in young children of Venta de Baños. To estimate the importance of the associated pathology to these infections. To evaluate the adequacy of the imaging to the proposals supplied by the NICE Guide about UTI in childhood. Patients and methods: retrospective study reviewing the clinical records of the children born in Venta de Baños, between 2001 and 2006, taking information about urine cultures in their two first years of life, results, treatment and follow up. The imaging studies are compared with those proposed by the NICE Guide in august 2007. Results: two hundred ninety-three clinical records were reviewed. The accumulated incidence of UTI has been 7.5%. Ecography was done in 90% of UTIs, VCUG (voiding cistoureterography) in 66% and DMSA (technetium-99m dimercaptosuccinic acid) in 18%. Ten percent of boys and 25% of girls had vesicouretal reflux (VUR), all of them in grade II. Following the NICE Guide recommendations, 75% of the VCUG were not indicated and the late DMSA was not done in 76% of the cases in which it would have been indicated. Conclusions: our accumulated incidence of urinary infection is slightly higher than in other series. Our children had not complicated UTI and a low degree RVU. We have carried out fewer DMSA and more VCUG than the recommended in current guidelines. We have proposed for our health area a less aggressive follow up of urinary tract infection (AU)
