The revised version of the Brazilian Healthy Eating Index is an indicator of dietary quality developed according to current nutritional recommendations. Dietary data were obtained from a population-based survey, the 2003 Inquérito de Saúde e Alimentação (ISA-Health and Diet Survey)-Capital. The Revised Index consists of 12 components: nine food groups included in the 2006 Brazilian Dietary Guidelines, in which daily portions are expressed in terms of energy density; two nutrients (sodium and saturated fats), and SoFAAS (calories from solid fat, alcohol and added sugar). The Revised Brazilian Healthy Eating Index allows for the measurement of dietary risk factors for chronic diseases, evaluating and monitoring the diet at both individual and population levels.
Dietary quality maintained among overweight Brazilian women enrolled in a primary healthcare service
Journal of Health Population and Nutrition, 2014
With this in mind, studying diets with various food combinations is more frequently recommended than intake assessment for individual food items or nutrient contribution as food is not consumed in isolation and reflects the choice of a certain lifestyle (6). In this context, the Healthy Eating Index (HEI) assesses the overall intake of food and nutrients and, simultaneously, includes different aspects of the diet (5). Thus, this study aimed to evaluate the dietary quality maintained among overweight women enrolled in a primary healthcare service in Brazil. In this country, the scientific research output on nutrition in primary healthcare is mainly related to the evaluation of nutritional status of children. Investigations on food consumption represent only 12.8% of the bibliography (7). MATERIALS AND METHODS Study design and sample We conducted a cross-sectional study among overweight women enrolled in a primary healthcare service in Belo Horizonte, Brazil. Participants of the study included women who underwent nutritional care in 2009. The inclusion criterion adopted in the study was: being overweight

Objective: To evaluate the educational influence in the relative validation of a semiquantitative food frequency questionnaire (FFQs) for adults in the city of Viçosa, Brazil. Design and subjects: Four 24-h dietary recalls (reference method) were applied to a sample of 94 adults of both genders, at intervals of 1 month. At the end of the study, an FFQs consisting of 58 food items was also applied. Then, the individuals were divided into two main groups according to their educational level (lower and higher). The dietary data were calculated by the Diet Pro 4.0 software and analyzed according to differences of means or medians and Pearson's correlation coefficients. These coefficients were adjusted by the energy and corrected by the within-person variance for each educational group, considering the extreme quartiles of the data distribution. Results: The intake of energy and nutrients, based on the 24 h dietary recalls, was inferior for the lower educational group (Po0.05). For the FFQs, just the protein and calcium intakes were statistically different, suggesting interference of the education variable in this assessment. Overestimations in the FFQs were identified in the analyses of means and medians for vitamin C and retinol intakes in the lower education group and for retinol in the higher education one. However, when evaluated by correlation coefficients non-adjusted and adjusted, they were well correlated. On the other hand, lipid (r ¼ 0.34) and calcium (r ¼ 0.13) coefficients of the group with less instruction showed beneath the desirable values, suggesting weak consistence of the estimates provided by the FFQs for these nutrients. Correlation means of r ¼ 0.65 and 0.54 were found for the higher and lower educational groups, respectively.
A New Food Guide for the Portuguese Population: Development and Technical Considerations
Journal of Nutrition Education and Behavior, 2006
The methodological approach used for the development of a new food guide for the Portuguese population is discussed. The new food guide, composed of seven groups, was achieved with the assistance of an expert panel, using existing international recommendations and nutrient composition tables. A range of recommended food portions was established for the groups of fats and oils; milk and dairy products; meat, fish, seafood, and eggs; pulses; potatoes, cereals, and cereal products; vegetables; and fruits. Posters and leaflets were produced and presented to the media with the support of health authorities and the scientific community. The dissemination materials were freely distributed to institutions and professionals responsible for health promotion.

This manuscript aims to describe the methodological, operational, and quality control aspects of the assessment of dietary intake in children under five years of age participating in the Brazilian National Survey on Child Nutrition (ENANI-2019), a household survey in a probability sample of Brazilian households. Two instruments were developed to assess child feeding practices - a structured, current status-type questionnaire and a 24-hour dietary recall (24HR), both installed in a mobile data collection device used by previously trained interviewers. A Photographic Manual for Quantification of Children's Dietary Intake was specifically developed for and used in the survey as a support aid to identify and quantify foods reported in the 24HR. During the fieldwork, continuous quality control of the records was performed. Data errors or incomplete data in the system were corrected, and the fieldwork team was systematically contacted and informed on their performance, with reiterated...
