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
Objective. To examine the effects of an intervention program held by teachers previously trained in nutrition, on the consumption of low nutrient, energy-dense (WED) foods, of children attending elementary schools. Method. 464 children (239 female, 6 to 12 years) from seven elementary Portuguese schools participated in this randomized trial. Three schools were allocated to the intervention, and four to the control group. The intervention program was based on the Health Promotion Model and social cognitive theory. Teachers previously trained by researchers in nutrition and healthy eating implemented the intervention in the classroom from November 2008 to March 2009. Sociodemographic, anthropometric, physical activity, and dietary assessments were performed before (2007/2008) and at the end of the intervention (2009). Dietary intake was gathered by a 24-hour dietary recall and two groups of LNED foods were defined, namely SSBs and solid LNED foods. Results. Children from intervention group reported a reduction whereas the control group reported an increase in solid LNED foods consumption. The odds of increasing solid LNED foods consumption was 0.48, 95%CI (0.24, 0.95) in the intervention schools. Conclusion. Our study provides further support for the success of intervention programs aimed at limiting the consumption of solid LNED foods in children.

Abstract
BACKGROUND/OBJECTIVES: The elderly constitute a population group with a high prevalence of non-communicable chronic diseases and high risk of malnutrition. The aim of this study was to identify factors associated to nutritional risk in free-living European elderly. SUBJECTS/METHODS: The sample included 644 European citizens, free living in the community, aged 65 years or more. The sample was quota controlled for age groups (65-74, >= 75 years), gender (male/female) and living circumstances (living alone/with others). Logistic regression was performed to identify factors associated with nutritional risk. RESULTS: Several variables regarding socio-demographic characteristics, food choice, health status and the satisfaction with food-related life were included in the analysis. According to the recoded score of the 'Determine your nutritional health' (NSI checklist), 53% of the elderly were at nutritional risk. Nutritional risk was more likely to occur in elderly who considered that it was more important to choose foods 'easy to chew'; with lower average number of fruit and vegetables (F&V) intake episodes and lower score for general health. It was also found in nod-married participants; those that did not identify changes in their appetite; and those that felt changes in health status. In this sample, the lowest nutritional risk was found for body mass index (BMI) around 18.5 kg/m(2). Country of residence, gender and age were not found to have a significant effect on nutritional risk. CONCLUSIONS: Attention should be drawn to the living circumstances, changes in appetite or health, the general heath perception, F&V intake, choice of foods easy to chew and having a low or high BMI.
