Cuestionario de calidad de vida relacionado con el estado nutricional (CaVEN) / Quality of life questionnaire related to nutritional status

Objetivo: Construir y validar un instrumento para medir la calidad de vida percibida en relación con el estado nutricional. Material y método: Mediante grupos focales y entrevistas con expertos en nutrición se identificaron las dimensiones con mayor afectación. Tras la prueba de jueces se definió el cuestionario CaVEN. Para su validación se realizó un estudio multicéntrico, participando 7 hospitales españoles. La validez factorial del cuestionario se evaluó mediante análisis factorial exploratorio, solución en componentes principales y rotación varimax; la validez de criterio mediante correlaciones con los Gold standard nutricionales. La fiabilidad se estimó mediante el coeficiente α de Cronbach. Resultados: Se construyó un cuestionario de 26 ítems con 6 dimensiones de salud. Se aplicó a 68 pacientes que fueron valorados en las Unidades de Nutrición. El valor del test KMO fue de 0,756, mostrando que se adecua al modelo de Análisis Factorial. Se comprobó la existencia de direcciones principales de inercia (Bartlett p < 0,01). Las 6 dimensiones presentaron una varianza acumulada del 77,670. Se observó una relación directa entre la Valoración Global Subjetiva y CaVEN (p < 0,01) y entre Mini Nutritional Assessment Short (p = 0,02) lo que se interpretó como a mayor afectación del estado nutricional, peor calidad de vida detectada por el CaVEN. Conclusiones: El cuestionario CaVEN se ha revelado como un instrumento útil para evaluar la calidad de vida relacionada con el estado nutricional, incluso en colectivos con poca afectación del estado nutricional (AU)

Objective: To build and validate an instrument to measure the perceived quality of life in the nutritional status. Material and methods: By focal groups and interviews with nutrition experts, the dimensions with greater affectation were identified. After the judge test, the CaVEN questionnaire was defined. For its valuation a multicentric study was performed, participating 7 Spanish hospitals. The internal structure of the questionnaire was evaluated by explanatory factorial analysis. Reliability was tested using the Cronbach α coefficient and the validity of the criteria with the nutritional Gold Standards. Results: A questionnaire of 26 items with 6 health dimensions was built. It was applied to 68 patients that were valued in the Nutrition Units. The test KMO was 0.756, showing a good accuracy in the Factorial Analysis. The existence of principal dimension of inertia was found (Bartlett p < 0.01). The 6 dimensions showed an accumulative variance of 77.670. It was observed a direct relationship in the Subjective Global Valuation and CaVEN (p < 0.01) and with the "Mini Nutritional Assessment Short" (p = 0.02), which was interpreted as the greater affectation of the nutritional status, the lower the quality of life detected by the CaVEN. Conclusions: The CaVEN questionnaire has proved a useful tool for assessing the quality of life related to nutritional status, even in groups with little nutritional alterations (AU)

25 años de investigación en nutrición y alimentación en el espacio iberoamericano del conocimiento / 25 years in nutrition and food research in the iberoamerican knowledge área

Introducción: La investigación suele considerarse un indicador del grado de desarrollo. La investigación de un área problemática como la alimentación y nutrición para una determinada región, debería tener un impacto sobre la producción científica en consonancia con la importancia del problema, la capacidad investigadora y los recursos disponibles para generar dicha investigación. Objetivo: Conocer algunos indicadores de la investigación iberoamericana en nutrición y alimentación. Método: Estudio retrospectivo de la producción científica iberoamericana en nutrición y alimentación en los últimos 25 años. Los datos se obtuvieron de la base bibliográfica Science Citation Index Expanded (SCI), Journal Citation Reports Database. Science edition 2011 (Web of Knowledge, Thomson Reuters), y la base de datos del Banco Mundial. Resultados: Se registraron 49.808 artículos, el 3,20% de la producción en Ciencias de la Salud recogida en SCI. La evolución se ajustó al modelo exponencial, N&D (R2 0,962) y FS&T (R2 0,995). La producción media en N&D por población media fue mayor en España con 0,659 artículos/millón. Los mayores índices de productividad y rentabilidad se presentaron en Guatemala 12,963 artículos/1.000 investigadores, y 1,486 artículos/ millón $ respectivamente. La producción media en FS&T de los países por población media fue mayor en Cuba con 21,624 artículos/millón. El índice de productividad fue mayor en Uruguay con 25,999 artículos/mil investigadores. El índice de rentabilidad fue mayor en Guatemala con 0,271 artículos/ millón $. Conclusiones: Existe crecimiento exponencial en las dos categorías estudiadas, N&D y FS&T. La productividad y rentabilidad fue mayor en países con bajo presupuesto en I+D (AU)

Introduction: Research is usually considered a reliable indicator of the degree of development. Research in a problematic area such as food and nutrition for a given region, should have an impact on scientific production in agreement with the importance of the problem, the research capacity and the available resources for generating such a research. Objective: To identify some indicators of Iberoamerican research in nutrition and food. Method: Retrospective study of Iberoamerican scientific production in nutrition and food in the last 25 years. The data were obtained from the bibliographic database Science Citation Index Expanded, Journal Citation Reports Science Edition Database 2011, both included in the Web of Knowledge (Thomson Reuters), and the database of the World Bank. Results: 49,808 papers were registered, the 3.20% of the Health Sciences collection in SCI. The evolution was fitted to an exponential model, N&D (R2 0.962) and FS&T (R2 0.995). The average production in N&D per average population was higher in Spain with 0.659 papers/million. The highest rates of productivity and profitability were f oundin Guatemala with 12.963 papers/1000 researchers and 1.486 papers/million $ respectively. The average production in FS&T of the different countries per average population was higher in Cuba with 21.624 papers/million. The productivity index was higher in Uruguay with 25.999 papers/thousand researchers. The profitability index was higher in Guatemala with 0.271 papers/million $. Conclusion: There is exponential growth in the two categories studied N&D and FS&T. Productivity and profitability was higher in countries with low R&D (Research & Development) budget (AU)
