Food Frequency Questionnaires (FFQ) para el estudio del consumo de cacao en estudiantes de ciencias de la salud

Tot i que el cacau i la xocolata són una gran font de polifenols, aquests aliments no es troben entre les fonts alimentàries de polifenols més consumides. Algunes dades suggereixen un aport inferior al 10% de polifenols a través d’aquests. Aquest fet podria ser causa de les diferents metodologies i l'enfocament dels qüestionaris de freqüència de consum d'aliments (FFQ) utilitzats en aquests estudis. La majoria de FFQ validats utilitzen una extensa llista d'aliments per a les fruites i verdures, però no distingeixen adequadament les diverses fonts de xocolata i cacau. Aquests fets recolzen la necessitat d'una avaluació del consum de productes de cacau per tal de poder conèixer la ingesta real de cacau, especialment en la població jove, on la xocolata és un aliment consumit freqüentment.

FFQ para el estudio del consumo de cacao (portugués)

Cocoa has been highlighted as a food with potential benefits to human health due to it being animportant source of polyphenols. However, few studies show the contribution of cocoa andchocolate products in polyphenol intake. The aim of this work was to develop and validate afood frequency questionnaire (FFQ) evaluating the intake of food products containing cocoa (CFFQ).A sample of university students was recruited to complete the 90-item questionnaire inSpain and therefore in Spanish (http://diposit.ub.edu/dspace/handle/2445/60475) and in Portugalin a Portuguese version, which is the present document. The developed FFQ questionnaire canbe considered as a valid option for assessing the consumption frequency of cocoa- andchocolate-derived products, thereby allowing the evaluation of cocoa polyphenol intake infurther studies.

Consumo y convergencia mediática de la prensa local en Cataluña

Los nuevos hábitos de consumo de medios en el marco de la convergencia digital están propiciando un cambio en las estrategias de los medios de comunicación. Mientras unos usuarios siguen prefiriendo la radio, la televisión y la prensa tradicional para informarse otros participan de la experiencia digital en internet (blogs, redes sociales...) y dispositivos móviles, etc. En este panorama es complicado precisar dónde nace y termina el contenido o hasta qué punto es la participación del usuario quien (re) construye la información; así los contenidos mutan y se diluyen en varios soportes. En este contexto, la prensa local también vive las consecuencias del nuevo paradigma y asume los retos del reacomodo del sector ante la nueva realidad. Esta comunicación presenta las conclusiones del estudio cualitativo con entrevistas en profundidad a los responsables de medios locales en Cataluña sobre sus usuarios, contenidos y soportes en el marco de la convergencia digital.

La desigualdad en el consumo familiar. Diferencias de género en la España contemporánea (1850-1930)

In the last few years, Economic Theory has revised two basic ideas around the economics of the household: that family income is the result of the individual income of each of its members (income pooling), and that all family members living in the household have equal access to its resources. Unequal access to family resources (among women and men, on the one hand, and among the elderly, adults and children, on the other), is now understood as an input (for instance, that women eat less food and of worst quality than men), and as an output (for instance that women have poorer health, higher epidemic mortality, or are less tall than men as a result, among other things, of having received less food and poorer medical care, and/or of a heavier workload). Despite the fact that inequality in intra‐family consumption has become the center of attention in academic and international agencies, it can still not be found in the agenda of Economic History. In this paper we look at some of the resources consumed by Spanish families in the 19th century: food, alcoholic beverages, clothes and shoes. Medical topographies, our main source, suggest that unequal access to family resources among household members had a strong impact on their health and wellbeing.
