Objective: To examine trends in food availability for Portugal during the last 4 decades (1974-2011) and analyze such changes in accordance with the nutritional transition theory.

Methods: Food balance sheets from Portugal from 1974 to 2011 were analyzed for potential trends by linear regression to study the availability of protein, fat, carbohydrate, ethanol, and total energy and the availability of the following food groups: (i) cereals and tubers; (ii) vegetables; (iii) fruit; (iv) milk; (v) meat, fish, and eggs; (vi) fat; (vii) pulses; (viii) alcoholic beverages; and (ix) sugar and sweeteners. A comparison regarding protein, fat, and carbohydrate availability and WHO recommendation was also performed.

In Portugal people aged 65 and above will be the populational group with the highest growth rate of the next decades. Healthy ageing constitutes a challenge as not only the number of years lived are essential, but also the quality of life becomes a priority. The aim of this study was to understand the relationship between health self-perception (HSP), food consumption and nutritional status among Portuguese older adults.

The knowledge of the food pattern of a population is crucial for establishing nutritional and epidemiological profiles, as well as for controlling the market of foodstuffs and to help in the management of stock of staple foods. This study aims to evaluate food consumption and its association with the underlying motives for consumers' food choices, through the application of a Food Frequency Questionnaire (FFQ) followed by a Food Choice Questionnaire (FCQ). Face to face interviews were conducted with 503 participants, recruited at their homes, workplaces, health centers and other central locations in Cape Verde, only including subjects aged ≥18 years, without a self-reported history of chronic diseases.

The aims of this study were: (i) to estimate the dependency between BMI and waist:height ratio (WHtR) as measures of general and abdominal adiposity, and (ii) to evaluate the influence of socio-demographic factors on both measures and on their dependency in risk classification. Data from a cross-sectional study conducted in 2009 among a representative sample of 3529 Portuguese adults were used. Height, weight and waist were measured and socio-demographic data (sex, age, education level, occupational status, marital status, region of residence) were obtained.

The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project.

Objective: To examine which factors act as mediators between parental educational level and children's fruit and vegetable (F&V) intake in ten European countries.

Design: Cross-sectional data were collected in ten European countries participating in the PRO GREENS project (2009). Schoolchildren completed a validated FFQ about their daily F&V intake and filled in a questionnaire about availability of F&V at home, parental facilitation of F&V intake, knowledge of recommendations about F&V intake, self-efficacy to eat F&V and liking for F&V.

The aim of this study was to evaluate the effect of a lifestyle intervention programme (nutrition and exercise counselling) on metabolic syndrome (MS) components, adipokines (leptin, adiponectin) and ghrelin levels in overweight children. A total of 61 overweight children aged 7-9 years (≥ 85th body mass index (BMI) percentile; 27 boys/34 girls) were randomly assigned and completed a 1-year individual (IT) or group-based treatment (GT). Anthropometric and biochemical parameters were assessed at baseline, at 6 months and at 1 year.

Background: Body fat is related to changes in lipid profile, blood pressure and metabolism of insulin and glucose, known as the metabolic syndrome (MS). The aim of this study was to estimate the prevalence of metabolic syndrome (MS) and its components among overweight and obese Portuguese schoolchildren, and to identify associated clinical and biochemical characteristics.

Methods: A total of 82 children (14 overweight and 68 obese; 40 boys and 42 girls) aged 7-9 years, underwent anthropometric measurements.

Article Synopsis
  • The study aimed to determine how many schoolchildren in Aveiro, Portugal are overweight or obese, using two different criteria: IOTF and CDC.
  • The data collected from 905 children (ages 7-9) showed that the IOTF cut-offs indicated a lower prevalence of overweight and obesity compared to the CDC standards, with notable differences in obesity rates between boys and girls.
  • Overall, the findings highlight a significant issue of excess weight among children in Aveiro, particularly among girls, and indicate that the IOTF criteria may underestimate obesity prevalence.

The first results of the Women's Health Initiative dietary intervention trial were published in the USA in February. This is a colossal intervention designed to see if diets lower in fat and higher in fruits, vegetables and grains than is usual in high-income countries reduce the incidence of breast cancer, colorectal cancer, heart disease and other chronic diseases, in women aged 50-79 years. As interpreted by US government media releases, the results were unimpressive.

Background/aims: The Pro Children Project was designed to assess fruit and vegetable consumption in European schoolchildren and their parents, as well as determinants of the children's consumption patterns. A second objective was to develop and test strategies, applicable across Europe, for promoting consumption of fruits and vegetables among schoolchildren and their parents. In this paper, the rationale, theoretical background, overall design and implementation of the project is presented.
