Abstract
Objective: to identify diet quality time trends in Portuguese elderly households and the association of diet quality with sociodemographic characteristics. Design: Set of four cross-sectional studies. Setting: Portuguese population. Subjects: nationally representative samples from Household Budget Surveys (1989-1990, 1994-1995, 2000-2001 and 2005-2006 versions). Households with members aged >= 65 years were categorized as solitary elderly female, solitary elderly male, or elderly couple (composed of one elderly female and one elderly male) and compared with adult households with the same composition. Methods: Diet quality was assessed through a revised version of the Healthy Diet indicator (HDIr). Univariate and multiple backward linear regression models were used to study the association with sociodemographic characteristics. Results: Mean values of dietary index were low and the proportion of elderly households with low diet quality (HDIr <= 4) was high (between 47.4% and 68.4%). However, the frequency of HDIr inadequacy for adult household was even higher (P<0.05). in general, adjusted coefficients for survey year, educational level of the household head, and eating out expenses were inversely associated with HDIr; whilst semi-urban and rural location of the households predicted higher HDIr values. exceptions were found in elderly male households where the educational level of the household head was positively associated with HDIr values. Conclusions: overall, diet quality was low and decreased over time but lonely elderly female and elderly couple households had higher values of HDIr. adherence to a healthier diet was associated with lower educational level of the household head and location of the household in less urbanized areas.

Abstract
Objective To identify dietary availability and its time trends in elderly Portuguese households. Design A set of four cross-sectional studies based on the Household Budget Surveys was used. The dietary data were described using the daily per capita availability of food and beverages, energy and selected nutrients (macronutrients, different lipid fractions and simple sugars). Differences between elderly household types and time trends were studied. Setting Portuguese Household Budget Survey data from 1989/1990, 1994/1995, 2000/2001 and 2005/2006. Subjects Households with members aged 65 years were selected and categorized as solitary elderly female, solitary elderly male or couple (composed of one elderly female and one elderly male). Results While cereals, fats/oils, potatoes and sugar/sugar products decreased, an increase occurred in milk/milk products, fruits, bottled water, fruit/vegetable juices and soft drinks (P<005). The highest values for foods and beverages were mostly found in couples, while the lowest ones were from solitary males. Exceptions were observed for cereals, eggs, milk/milk products, vegetables, fruits and non-alcoholic beverages, higher in solitary females; and for sugar/sugar products and alcoholic beverages, higher in solitary males. Over time, total energy and carbohydrates decreased while proteins and saturated fatty acids increased (P<0001). Lipids increased in solitary males and couples (P<005). Simple sugars increased in solitary males but decreased in solitary females and couples (P<005). Conclusions The increases in fruits and vegetables in solitary females accord with a healthier food pattern, but overall imbalances in the macronutrient profile for all elderly households may imply a decreasing diet quality.

Abstract
Our aim was to adapt for Portuguese and validate the flexible and rigid control subscales of eating behaviour proposed by Westenhoefer et al. (1999) and to analyse their relationship with socio-demographic and anthropometric variables. One sample from the general population (n = 231) and another composed by higher education students (n = 257) were evaluated. The adaptation of the subscales involved their translation, back translation and cultural adaptation. The subscales' final version showed unifactorial structure and acceptable internal consistency in both samples (Cronbach's alpha between 0,750 and 0,817). Higher scores in each subscale correspond to higher dietary restraint. Women had higher levels of both types of control. For men age was positively associated with flexible control, and for women education was positively associated with both types of restraint. In the students' sample, rigid control significantly predicted BMI (positive association). The present study supplies an instrument to assess flexible and rigid control of eating behaviour adapted to the Portuguese population.

Abstract
Background/Aims: Personalised nutrition has potential to revolutionise dietary health promotion if accepted by the general public. We studied trust and preferences regarding personalised nutrition services, how they influence intention to adopt these services, and cultural and social differences therein. Methods: A total of 9,381 participants were quota-sampled to be representative of each of 9 EU countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway) and surveyed by a questionnaire assessing their intention to adopt personalised nutrition, trust in service regulators and information sources, and preferences for service providers and information channels. Results: Trust and preferences significantly predicted intention to adopt personalised nutrition. Higher trust in the local department of health care was associated with lower intention to adopt personalised nutrition. General practitioners were the most trusted of service regulators, except in Portugal, where consumer organisations and universities were most trusted. In all countries, family doctors were the most trusted information providers. Trust in the National Health Service as service regulator and information source showed high variability across countries. Despite its highest variability across countries, personal meeting was the preferred communication channel, except in Spain, where an automated internet service was preferred. General practitioners were the preferred service providers, except in Poland, where dietitians and nutritionists were preferred. The preference for dietitians and nutritionists as service providers highly varied across countries. Conclusion: These results may assist in informing local initiatives to encourage acceptance and adoption of country-specific tailored personalised nutrition services, therefore benefiting individual and public health.

Abstract
To analyze the simultaneous effects of sociodemographic variables and time on each food group contribution to total Portuguese elderly household food availability. Four cross sectional Portuguese Household Budget Surveys were used. A multivariate analysis of variance (MANOVA), using a general linear model (GLM), was applied to analyze the simultaneous effects of sociodemographic variables and time. Portuguese population. Nationally representative samples of households with members aged a parts per thousand yen 65 years were selected and categorized as solitary elderly female, solitary elderly male, or couple (one elderly female and one elderly male). Samples included 1,967 households in 1989-1990, 2,219 households in 1994-1995, 2,533 households in 2000-2001 and 2,441 households in 2005-2006. The simultaneous effects of sociodemographic variables and time were significant for all food groups (P < 0.001). The highest contribution for the total household food availability was found for cereals, potatoes, alcoholic beverages, nonalcoholic beverages and fruits. The effects were large for "household food availability" and medium for "elderly household type", "urbanization degree", "income", "food expenses" and "eating out expenses". Solitary elderly male households had the highest proportion of cereals and alcoholic beverages, whilst solitary elderly female households had higher availability of milk/milk products and fruits. Households located in urban areas had higher contribution of milk/milk products while rural, had higher contribution of potatoes. The simultaneous effect of the studied variables on food group contribution to total household food availability can be considered when addressing dietary recommendation for providing an insight into the motivations associated with food purchases.
