Sisvan food intake markers from six to 23 months: critical analysis and validation.

Objective: To explore the internal structure and analyze evidence of measurement invariance of the Sisvan form of food intake markers of the Food and Nutrition Surveillance System (Sisvan) for children aged six to 23 months.

Food and Nutrition Surveillance System markers predict diet quality.

Objective: To investigate the performance of food consumption markers of the Food and Nutrition Surveillance System (Sisvan) in assessing the overall dietary quality.

Methods: The study was carried out based on the reproduction of responses to markers in 24-hour recall data from 46,164 individuals aged ≥ 10 years, from the 2017-2018 Household Budget Survey (POF). Seven Sisvan markers were evaluated, and two scores were calculated for each participant, based on the sum of the number of healthy food markers (beans, fruits, and vegetables, ranging from 0 to 3) and unhealthy (hamburgers/sausages, sweetened beverages, instant noodles/salt snacks/crackers, stuffed cookies/sweets/candies, ranging from 0 to 4) consumed.

Sisvan food intake markers: structure and measurement invariance in Brazil.

Objective: To characterize the internal structure of the Food and Nutrition Surveillance System (Sisvan) form of food intake markers for individuals over 2 years of age and to investigate measurement invariance between Brazilian macro-regions, life stages and over the years.

Methods: A parallel analysis with factor estimation was carried out, complemented with exploratory factor analysis using all Sisvan records with valid responses in the country in 2015 (n = 298,253). Only the first record per individual was considered.

Diet quality and associated factors in Brazilian undergraduates during the COVID-19 pandemic.

Background: Diet quality is associated with psychobiological, psychological, biological, and physiological factors of individuals, and in the context of prolonged stress, such as the COVID-19 pandemic, it can lead to a worsening of the quality of food for undergraduates. This study aimed to analyze diet quality and associated factors in Brazilian undergraduates.

Methods: Data were collected from 4,799 undergraduate students from all Brazilian regions, from August 2020 to February 2021.

Development and Validation of a Protocol for Pregnant Women Based on the Brazilian Dietary Guidelines.

Objective:  To develop and validate a protocol for the use of the Dietary Guidelines for the Brazilian Population (DGBP) in the individual dietary advice for pregnant women assisted in primary healthcare (PHC).

Methods:  Methodological study that involved the elaboration of a protocol in six steps: definition of the format, definition of the instrument to evaluate food consumption, systematization of evidence on food and nutrition needs of pregnant women, extraction of DGBP recommendations, development of messages of dietary guidelines and content, and face validity. The analyses of the validation steps were carried out by calculating the Content Validity Index (CVI) and thematic content analysis.

Developing a protocol based on the Brazilian Dietary Guidelines for individual dietary advice in the primary healthcare: theoretical and methodological bases.

To describe the methodology of development of a protocol for application of the Brazilian Dietary Guidelines by primary healthcare professionals in individual dietary advice. A five-step approach was followed: (1) format definition; (2) definition of the instrument for assessment of individuals' food consumption; (3) Dietary Guidelines' content extraction; (4) protocol content development; (5) content and face validity. An example from Brazil was displayed with the development of a protocol to guide healthcare professional decision-making when providing nutrition advice based on the Brazilian Dietary Guidelines.

Food Insecurity and Associated Factors in Brazilian Undergraduates during the COVID-19 Pandemic.

Undergraduates may face challenges to assure food security, related to economic and mental distress, especially during the COVID-19 pandemic. This study aimed to assess food insecurity and its associated factors in undergraduates during the COVID-19 pandemic. An online cross-sectional study was conducted from August 2020 to February 2021 with 4775 undergraduates from all Brazilian regions.

[Development and validation of performance indicators of the National School Food Program management].

The evaluation of the National School Food Program (PNAE) is a strategic action to ensure the quality of management. This study aims to develop and validate an instrument of performance indicators to assess the management of the PNAE in the national context. A psychometric study was carried out for the development and validation of performance indicators.

Two validity evidences of the ESQUADA and Brazilians' dietary quality levels.

Objective: Assess two validity evidences of the diet quality scale (ESQUADA) for the selection of items with better discrimination of the Brazilians' diet quality and propose a description in score levels.

Methods: Brazilian adolescents and adults residing in the country (n = 2,059) answered an online questionnaire with 52 items, shared on social networks and email lists between March and April 2018. Statistical tests were applied to analyze the validity and reliability of the instrument's evidence.

Evaluation of quality indicators for management of the National School Feeding Program in Brazil: a systematic review.

This article aims to identify studies that developed quality indicator for the management of the National School Feeding Program (PNAE, in Brazilian context) and to critically appraise the properties of their instruments. Systematic review using Scopus, Lilacs, Pubmed and Web of Science for data collection. The search was limited to studies between 2009 and 2019.

[Intra-family and school violence scale using the Item Response Theory].

Violence is a global public health problem and may be of a physical, sexual, or psychological nature, or due to negligence. In order to evaluate this situation, instruments are needed that can assess this widely diverse scenario. The scope of this research was to develop a scale to evaluate intra-family and school violence.

Item Response Theory-based validation of a short form of the Disordered Eating Attitude Scale (DEAS-s) to a Brazilian sample.

This study aimed to validate a short version of the Disordered Eating Attitude Scale (DEAS-s). To this end, 2,902 adult individuals answered the original DEAS and informed age, weight, and height. Data were analyzed using the full-information factor analysis and Item Response Theory (IRT) analysis.

[Dietary patterns of children and socioeconomical, behavioral and maternal determinants].

Objective:: To identify dietary patterns of children and to verify their association with socio-economical, behavioral and maternal determinants.

Methods:: A cross-sectional study with a random sample of 328 children aged 8 and 9 years. Dietary intake was assessed by food records in three nonconsecutive days and measured in grams of food groups and nutrients.

[Metabolic syndrome risk assessment in children: use of a single score].

Objective:: To calculate a score of metabolic syndrome (MetS) in children and set a cutoff point of this score for the prediction of MetS risk.

Methods:: The study included a random sample of 348 children aged 8 and 9 years of Viçosa, Southeast Brazil. Factor analysis by principal components (PCA) was used to determine, among various risk factors, those with higher degrees of intercorrelation.
