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. Linear regression analyses were used to assess the association between scores and diet quality indicators (ultra-processed foods, dietary diversity, and levels of saturated and trans fat, added sugar, sodium, potassium, and fiber in the diet). RESULTS: The score of healthy eating markers increased significantly with increasing dietary diversity and potassium and fiber contents in the diet, while the opposite trend was observed for the densities of added sugar, sodium, saturated and trans fat (p < 0.001). The score of unhealthy eating markers increased significantly with the increase in the consumption of ultra-processed foods and densities of added sugar, saturated and trans fat levels in the diet, while an inverse trend was observed for potassium and fiber (p < 0.001). The joint analysis of the combination of the two marker scores showed that individuals with better performance (3 in the healthy food score, and 0 in the unhealthy food score) have a lower number of inadequacies in nutrient consumption. CONCLUSION: Sisvan food consumption markers, quickly and easily applied and already incorporated into the Brazilian public health system, have good potential to reflect the overall dietary quality.

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. Next, multigroup confirmatory factor analysis was used to investigate configural, metric and scalar invariance between the five macro-regions (Midwest, Northeast, North, Southeast, South) and life stages (children, adolescents, adults, elderly) in the same reference year. Invariance was evaluated longitudinally using valid individual records from 2015 to 2019 (n = 4,578,960). The adequacy of fit indices was observed at each step. RESULTS: Acceptable fit indices and adequate factor loadings were found for a two-dimensional model, which grouped ultra-processed foods (factor 1) and unprocessed or minimally processed foods (factor 2). The two-dimensional structure, with the respective items in each factor underlying the set of markers, was equivalent across macro-regions, life stages and longitudinally, confirming the configural invariance. The weights of each item and its scale were homogeneous for all groups of interest, confirming metric and scalar invariances. CONCLUSIONS: The internal structure of the Sisvan form of food intake markers adequately reflected its conceptual foundation, with stability of factors related to healthy and unhealthy eating in configuration, weights and scale in the investigated categories. These findings qualify food and nutritional surveillance actions, enhancing the use of Sisvan food intake markers in research, monitoring, individual guidance, and care production in the Brazilian Unified Health System.

RESUMO OBJETIVO Caracterizar a estrutura interna do formulário de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) para indivíduos maiores de 2 anos de idade e analisar evidências de invariância de mensuração entre macrorregiões brasileiras, fases do curso da vida e ao longo do tempo. MÉTODOS Realizou-se análise paralela com estimação de fatores complementada com análise fatorial exploratória a partir de todos os registros de primeiro acompanhamento do Sisvan com respostas válidas no país em 2015 (n = 298.253). A seguir, empregou-se a análise fatorial confirmatória multigrupo para investigação de evidências de invariância configural, métrica e escalar entre as cinco macrorregiões (Centro-Oeste, Nordeste, Norte, Sudeste e Sul) e fases do curso da vida (crianças, adolescentes, adultos e idosos), no mesmo ano de referência. Avaliou-se a invariância longitudinalmente a partir de registros individuais válidos de 2015 a 2019 (n = 4.578.960). A adequação de índices de ajuste foi observada a cada etapa. RESULTADOS Verificaram-se índices de ajuste aceitáveis e valores de carga fatorial adequados para um modelo bidimensional, que agrupou alimentos ultraprocessados (fator 1) e alimentos in natura ou minimamente processados (fator 2). A estrutura bidimensional, com os respectivos itens em cada fator subjacente ao conjunto de marcadores, foi equivalente entre macrorregiões, fases do curso da vida e longitudinalmente, confirmando a invariância configural. Os pesos de cada item e sua escala foram homogêneos para todos os grupos de interesse, confirmando as invariâncias métrica e escalar. CONCLUSÕES A estrutura interna do formulário de marcadores do consumo alimentar refletiu adequadamente seu embasamento conceitual, com estabilidade dos fatores relacionados à alimentação saudável e não saudável em configuração, cargas e escala nos recortes investigados. Esses achados qualificam ações de vigilância alimentar e nutricional, potencializando o uso dos marcadores do consumo alimentar do Sisvan em pesquisas, monitoramento, orientação individual e produção de cuidado no Sistema Único de Saúde.

RESUMO OBJETIVO Investigar o desempenho dos marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) na avaliação da qualidade global da alimentação. MÉTODOS O estudo foi realizado a partir da reprodução de respostas aos marcadores em dados de recordatórios de 24 horas, de 46.164 indivíduos com idade menor ou igual a 10 anos, da Pesquisa de Orçamentos Familiares 2017-2018. Foram avaliados sete marcadores do Sisvan e calculados dois escores para cada participante, a partir do somatório do número de marcadores de alimentação saudável (feijão, frutas, verduras/legumes, variando de 0 a 3) e não saudável (hambúrguer/embutidos, bebidas adoçadas, macarrão instantâneo/salgadinhos/biscoitos salgados, biscoito recheado/doces/guloseimas, variando de 0 a 4) consumidos. Análises de regressão linear foram usadas para avaliar a associação entre os escores e indicadores de qualidade da alimentação (participação de alimentos ultraprocessados, diversidade e teores de gordura saturada, trans, açúcar de adição, sódio, potássio e fibra da dieta). RESULTADOS o escore de marcadores de alimentação saudável aumentou de forma significativa com o aumento da diversidade e dos teores de potássio e fibra da dieta, enquanto tendência oposta foi observada para as densidades de açúcar de adição, sódio, gordura saturada e trans (p < 0,001). Observou-se que o escore de marcadores de alimentação não saudável aumentou de forma significativa com o aumento da participação de alimentos ultraprocessados e dos teores de açúcar de adição, gordura saturada e trans da dieta, enquanto tendência inversa é observada para potássio e fibra (p < 0,001). A análise conjunta da combinação dos dois escores de marcadores mostrou que indivíduos com melhor desempenho (3 no escore de alimentos saudáveis, e 0 no de alimentos não saudáveis) possuem menor número de inadequações no consumo de nutrientes. CONCLUSÃO Os marcadores do consumo alimentar do Sisvan, aplicados de forma rápida e prática e já incorporados no sistema público de saúde brasileiro, possuem bom potencial para refletir a qualidade global da alimentação.

Medida do equilíbrio de decisões para redução do peso corporal entre pessoas com sobrepeso ou obesidade: uma revisão sistemática / Measuring the balance of decisions to reduce body weight among overweight or obesity people: a systematic review

Abordagens comportamentais têm contribuído para a efetividade do tratamento da obesidade. A avaliação do equilíbrio de decisões (ED) para redução de peso, isto é, o equilíbrio entre prós e contras da mudança de comportamento, é estratégica no tratamento, contribuindo para a pactuação de estratégias para o enfrentamento dos desafios. É necessário, porém, utilizar instrumentos válidos para mensurar o ED. Objetivo: Avaliar a qualidade de instrumentos de avaliação do ED para redução do peso corporal visando qualificar o cuidado da pessoa com obesidade no Sistema Único de Saúde (SUS). Métodos: Realizou-se revisão sistemática da literatura sobre o desenvolvimento e a validação de instrumentos em sete bases de dados seguindo a metodologia Cosmin. Variações dos termos psicometria, obesidade e ED foram combinadas com operadores booleanos. Em duplicada e independentemente, duas pesquisadoras realizaram: extração de dados, avaliação da qualidade e síntese de evidências, sendo as divergências solucionadas por consenso. Esta revisão foi registrada na base internacional Prospero (CRD42020197797). Resultados: Identificaram-se cinco estudos, sendo que três realizaram a tradução e adaptação transcultural do mesmo instrumento. Todos os estudos apresentaram ED em duas dimensões (prós e contras), mas usaram métodos duvidosos ou inadequados, e a maioria apresentou evidências científicas de muito baixa qualidade. Conclusões: Os resultados não sustentaram o uso dos instrumentos existentes nem sua tradução e adaptação transcultural, sendo necessário o desenvolvimento de um novo instrumento. Este estudo, ao disponibilizar um instrumento válido para uso no SUS, poderá contribuir para qualificar o cuidado da pessoa com obesidade e deter o crescimento da obesidade no país.

Introduction: Behavioral strategies have been adding to the effectiveness of obesity treatment. And the assessment of the decisional balance (DB) for weight reduction, that is, the balance between expected losses and gains around the behavioral changes, is strategic for managing obesity. The DB assessment may contribute to the agreement on strategies to face the challenges of the treatment. But, there is a need to use a valid instrument to assess the DB. Objective: evaluate the quality of instruments assessing DB for weight reduction to qualify obesity management in the Sistema Único de Saúde ­ SUS (Unified Health System). Methods: A systematic review of studies about instrument development and/or validation was carried out on seven databases using the Cosmin methodology. Terms related to psychometrics, obesity, and DB were combined with Boolean operators to guide the search. Two researchers performed independently and in duplicate: data extraction, quality assessment, and evidence synthesis, and divergences were resolved by consensus. This review was registered in the international database Prospero (CRD42020197797). Results: Five studies were identified. Three of them reported translations and cross-cultural validity of the same instrument. All analyses presented DB in two dimensions (pros and cons, but used doubtful or inadequate methods. Most of the evidence was very low rate. Conclusions: The results did not support the instrument's use, translations, or cross-cultural adaptation. It is necessary to develop a new tool. By providing a valid instrument for use in SUS, this study could contribute to qualifying the care of people with obesity and stopping the growth of obesity in the country.

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. RESULTS: As products of the steps, the protocol structure was defined and the dietary advice for pregnant women were elaborated, considering physiological changes, food consumption, nutritional and health needs, and socioeconomic conditions of this population. The protocol was well evaluated by experts and health professionals in terms of clarity, relevance (CVI > 0.8), and applicability. In addition, the participants made some suggestions to improve the clarity of the messages and to expand the applicability of the instrument with Brazilian pregnant women. CONCLUSION: The instrument developed fills a gap in clinical protocols on dietary advice for pregnant women focused on promoting a healthy diet, contributing to a healthy pregnancy. In addition, it demonstrates potential to contribute to the qualification of PHC professionals and to the implementation of the DGBP recommendations.

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. The instrument of the Brazilian Nutrition Surveillance System (SISVAN) was chosen to the food consumption assessment, which contains questions about the consumption of seven healthy or unhealthy food groups and one question about eating modes. The Guidelines' content extraction process led to the identification of recommendations related to the food consumption markers assessed by the SISVAN questionnaire. Then, a protocol was developed in a flowchart format, in which the professional's conduct is guided by the answer given to each question of the SISVAN instrument. For each 'non-compliant' answer (unhealthy eating practice), the professional is instructed how to provide recommendations and identify obstacles. Lastly, experts and healthcare professionals highlighted pertinence, clarity and usability of the protocol. This study provides the blueprint for the phase-wise development of protocols of application of the Dietary Guidelines and may contribute to promote healthier eating and ending malnutrition in all its forms.

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. The questionnaire contained socio-economic variables, the validated Brazilian food insecurity scale, and the ESQUADA scale to assess diet quality. The median age of the students was 22.0 years, and 48.0% reported income decreasing with the pandemic. Food insecurity was present in 38.6% of the students, 4.5% with severe food insecurity and 7.7% moderate. Logistic regressions showed students with brown and black skin color/race presented the highest OR for food insecurity; both income and weight increase or reduction during the pandemic was also associated with a higher OR for food insecurity, and better diet quality was associated with decreased OR for food insecurity. Our study showed a considerable presence of food insecurity in undergraduates. Policy for this population must be directed to the most vulnerable: those with brown and black skin color/race, who changed income during the pandemic, and those presented with difficulties maintaining weight and with poor diet quality.

[Development and validation of performance indicators of the National School Food Program management]. / Desenvolvimento e validação de indicadores de desempenho da gestão do Programa Nacional de Alimentação Escolar.

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. Twelve indicators were subsequently established and evaluated by an expert panel concerning seven attributes. The Delphi technique was used for the consensus of the expert panel, and the content validity of the indicators was analyzed with the Content Validity Ratio. Nutritionists working on the implementation of the PNAE assessed the relevance of the indicators by answering an online questionnaire to construct validity and reliability. Thirteen (43.3%, 13/30) experts participated in the Delphi round 1 and nine (69.2%, 9/13) completed the Delphi round 2. A new indicator was developed after the experts' suggestions. Furthermore, 281 nutritionists participated in this study assessing the relevance of the indicators. Overall, content and construct validity were achieved for 13 indicators. All were considered relevant and had the potential to promote the assessment of PNAE operational management.

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. Factor analysis was applied to study the dimensionality of the questionnaire items. Item response theory was applied to identify the discrimination and location of items on the continuum, construct the scale and assess the differential item functioning in terms of sex and age. RESULTS: Among the 52 items of the questionnaire, 25 had greater measurement accuracy, with adequate adjustment and reliability. The item on the habit of eating ultra-processed foods at home showed the best discrimination of diet quality. No item showed differential functioning regarding sex and age. In the construction of the ESQUADA, five diet quality levels were identified: very poor, poor, good, very good and excellent. It was observed that while breakfast cereals and/or cereal bars are more frequently consumed by individuals with "very poor" diet quality; nuts and/or walnuts are most often consumed by those individuals with "excellent" diet quality. CONCLUSION: The ESQUADA consists of 25 precise items with no differential functioning to assess the quality of Brazilians' diet. The construction of the ESQUADA made it possible to recognize food consumption and dietary practices characteristic of each level of diet quality.

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. The search strategy included search terms related to school feeding, program evaluation, and indicator. The indicators were evaluated using the Appraisal of Indicators through Research and Evaluation instrument. The search identified 1,355 studies, of which 14 were potentially relevant records and 10 met the inclusion criteria. Most studies used a literature review with consensus techniques in the development of the instrument and a frame work format to evaluate the PNAE. None of them presented evidence of validity of the instrument. The highest level was achieved on the domain 'Purpose, relevance and organizational context', followed by 'Stakeholder involvement', 'Additional evidence, formulation and usage', and 'Scientific evidence'. This review found gaps in the methodology of studies that had developed quality indicators for the management of PNAE. Future development of these instruments should include validity evidence.

Nutritional status and metabolic risk in adults: association with diet quality as assessed with ESQUADA. / Estado nutricional e risco metabólico em adultos: associação com a qualidade da dieta medida pela ESQUADA.

OBJECTIVE: To analyze the association between diet quality assessed with the Diet Quality Scale (ESQUADA) and the nutritional status and metabolic risk in adults. METHODS: The data included 1,147 adults aged 20 to 59, from the population-based study with complex sampling. Weight, height, tricipital (TSF) and subscapular (SSF) skinfolds, and waist (WC) and mid-arm (MAC) circumferences were measured. Body mass index (BMI) and mid-arm muscle circumference (MAMC) were calculated. Nutritional status and metabolic risk were classified considering BMI and WC values, respectively. Diet quality was assessed with ESQUADA. Data were collected at household using the Epicollect5 application. Diet quality (in scores) was analyzed as continuous data and later categorized. The confidence interval was used for comparison between groups, Fisher's exact test for an association study. Adjusted multiple linear regression models were also estimated. P < 0.05 was adopted for statistical significance. RESULTS: Overweight prevailed in 60.33% of individuals, especially among women (60.73%). High or very high metabolic risk was more frequent among women with "very good or excellent" diet quality. Higher diet quality score was associated with a reduction in TSF (ß = -0.07; 95%CI -0.13 - -0.01) and an increase in MAMC (ß = 0.09; 95%CI 0.00 - 0,18) in men and the reduction in weight (ß = -0.04; 95%CI -0.07 - -0.01), SSF (ß = -0.07; 95%CI -0.13 - -0,00) and WC in women (ß = -0.06; 95%CI -0.09 - -0.02). CONCLUSION: A better diet quality is positively associated with lean mass in men, and negatively with fat mass in men and women.

OBJETIVO: Analisar a associação entre qualidade da dieta medida pela Escala de Qualidade da Dieta (ESQUADA) e estado nutricional e risco metabólico em adultos. MÉTODOS: Analisaram-se dados de 1.147 adultos (de 20 a 59 anos), participantes de inquérito populacional com amostragem complexa por conglomerado. Aferiram-se peso, altura, pregas cutâneas tricipital (PCT), subescapular (PSE) e circunferências da cintura (CC) e do braço (CB). Calcularam-se índice de massa corporal (IMC) e circunferência muscular do braço (CMB). O estado nutricional e o risco metabólico foram classificados considerando valores de IMC e CC, respectivamente. A qualidade da dieta foi avaliada com aplicação da ESQUADA. Os dados foram coletados em domicílio com o aplicativo Epicollect5. A qualidade da dieta foi medida em escores e analisada de forma contínua e em categorias. O intervalo de confiança foi utilizado para comparação entre grupos, e o teste exato de Fisher, para estudo de associação, além de modelo de regressão linear ajustado. Adotou-se p < 0,05 para significância estatística. RESULTADOS: O excesso de peso prevaleceu em 60,33% dos indivíduos, especialmente entre mulheres (60,73%). O risco metabólico elevado ou muito elevado foi mais frequente entre mulheres com qualidade da dieta muito boa ou excelente. O maior escore de qualidade da dieta associou-se à redução da PCT (ß = -0,07; intervalo de confiança de 95% - IC95% -0,13 - -0,01) e ao aumento da CMB (ß = 0,09; IC95% 0 - 0,18) em homens e à redução do peso (ß = -0,04; IC95% -0,07 - -0,01), da PSE (ß = -0,07; IC95% -0,13 - -0,00) e da CC em mulheres (ß = -0,06; IC95% -0,09 - -0,02). CONCLUSÃO: A melhor qualidade da dieta associa-se positivamente a medidas antropométricas que indicam massa magra em homens e negativamente à massa gorda em homens e mulheres.

Methods The elaboration followed six methodological steps, namely: (1) protocol format definition; (2) definition of the instrument for assessing food consumption; (3) extracting applicable Food Guide recommendations for individual dietary guidelines; (4) evidence systematization on dietary and nutrition needs of the elderly; (5) development of nutritional guidelines messages for the elderly; (6) content and apparent validation and data analysis. Results As products of the steps, the protocol structure was defined and dietary guidelines were elaborated based on the nutritional and health needs of the elderly population, considering the functional capacity and physiological and social changes of this life cycle. The protocol was well assessed by experts and health professionals as to clarity, relevance (content validity index > 0.8) and applicability. In addition, the participants made some suggestions to improve the clarity of the messages and to expand the applicability of the instrument with elderly Brazilians. Conclusion The protocol can contribute to the qualification of dietary guidelines in PHC, dissemination of information from the Food Guide and promotion of comprehensive care and healthy aging of the population.

Estado nutricional e risco metabólico em adultos: associação com a qualidade da dieta medida pela ESQUADA / Nutritional status and metabolic risk in adults: association with diet quality as assessed with ESQUADA

RESUMO: Objetivo: Analisar a associação entre qualidade da dieta medida pela Escala de Qualidade da Dieta (ESQUADA) e estado nutricional e risco metabólico em adultos. Métodos: Analisaram-se dados de 1.147 adultos (de 20 a 59 anos), participantes de inquérito populacional com amostragem complexa por conglomerado. Aferiram-se peso, altura, pregas cutâneas tricipital (PCT), subescapular (PSE) e circunferências da cintura (CC) e do braço (CB). Calcularam-se índice de massa corporal (IMC) e circunferência muscular do braço (CMB). O estado nutricional e o risco metabólico foram classificados considerando valores de IMC e CC, respectivamente. A qualidade da dieta foi avaliada com aplicação da ESQUADA. Os dados foram coletados em domicílio com o aplicativo Epicollect5. A qualidade da dieta foi medida em escores e analisada de forma contínua e em categorias. O intervalo de confiança foi utilizado para comparação entre grupos, e o teste exato de Fisher, para estudo de associação, além de modelo de regressão linear ajustado. Adotou-se p < 0,05 para significância estatística. Resultados: O excesso de peso prevaleceu em 60,33% dos indivíduos, especialmente entre mulheres (60,73%). O risco metabólico elevado ou muito elevado foi mais frequente entre mulheres com qualidade da dieta muito boa ou excelente. O maior escore de qualidade da dieta associou-se à redução da PCT (β = -0,07; intervalo de confiança de 95% - IC95% -0,13 - -0,01) e ao aumento da CMB (β = 0,09; IC95% 0 - 0,18) em homens e à redução do peso (β = -0,04; IC95% -0,07 - -0,01), da PSE (β = -0,07; IC95% -0,13 - -0,00) e da CC em mulheres (β = -0,06; IC95% -0,09 - -0,02). Conclusão: A melhor qualidade da dieta associa-se positivamente a medidas antropométricas que indicam massa magra em homens e negativamente à massa gorda em homens e mulheres.

ABSTRACT: Objective: To analyze the association between diet quality assessed with the Diet Quality Scale (ESQUADA) and the nutritional status and metabolic risk in adults. Methods: The data included 1,147 adults aged 20 to 59, from the population-based study with complex sampling. Weight, height, tricipital (TSF) and subscapular (SSF) skinfolds, and waist (WC) and mid-arm (MAC) circumferences were measured. Body mass index (BMI) and mid-arm muscle circumference (MAMC) were calculated. Nutritional status and metabolic risk were classified considering BMI and WC values, respectively. Diet quality was assessed with ESQUADA. Data were collected at household using the Epicollect5 application. Diet quality (in scores) was analyzed as continuous data and later categorized. The confidence interval was used for comparison between groups, Fisher's exact test for an association study. Adjusted multiple linear regression models were also estimated. P < 0.05 was adopted for statistical significance. Results: Overweight prevailed in 60.33% of individuals, especially among women (60.73%). High or very high metabolic risk was more frequent among women with "very good or excellent" diet quality. Higher diet quality score was associated with a reduction in TSF (β = -0.07; 95%CI -0.13 - -0.01) and an increase in MAMC (β = 0.09; 95%CI 0.00 - 0,18) in men and the reduction in weight (β = -0.04; 95%CI -0.07 - -0.01), SSF (β = -0.07; 95%CI -0.13 - -0,00) and WC in women (β = -0.06; 95%CI -0.09 - -0.02). Conclusion: A better diet quality is positively associated with lean mass in men, and negatively with fat mass in men and women.

[Intra-family and school violence scale using the Item Response Theory]. / Escala de violência intrafamiliar e escolar usando a Teoria de Resposta ao Item.

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. In this study, the questionnaire on violence proposed by the World Health Organization and included in the Health and Nutrition Monitoring System - Nutrition of Students, was used. The questionnaire was applied to adolescents of both sexes, enrolled in public schools in the city of Piracicaba, Brazil, in 2014. The gradual response model of the Item Response Theory (IRT) was used to create the scale and analyze the questions contained in the questionnaire. The scale presented more precise information for levels of above average violence, implying greater applicability for populations at risk of intra-family and school violence. The use of the scale is proposed as a new approach to assess intra-family and school violence in future studies.

O objetivo desta pesquisa foi desenvolver uma escala para avaliar a violência intrafamiliar e escolar. Foi utilizado o questionário de violência, proposto pela Organização Mundial de Saúde e incluído no Sistema de Monitoramento da Saúde e Alimentação - Nutrição do Escolar. O questionário foi aplicado em adolescentes de ambos os sexos, matriculados em escolas públicas da cidade de Piracicaba, Brasil, em 2014. O modelo de resposta gradual da Teoria de Resposta ao Item (TRI) foi utilizado para criação da escala e análise das perguntas do questionário. A escala apresentou informação mais precisa para níveis de violência acima da média, sugerindo uma maior aplicabilidade para populações em risco de violência intrafamiliar e escolar. Sugere-se o uso da escala como nova abordagem para avaliar a violência intrafamiliar e escolar nos próximos estudos.

A new measure of health motivation influencing food choices and its association with food intakes and nutritional biomarkers in European adolescents.

OBJECTIVE: To develop a scale to assess health motivation influencing food choices and to explore its performance in the associations with food intakes and nutritional biomarkers. DESIGN: Psychometric study using cross-sectional self-report questionnaires and nutritional biomarkers. SETTING: Multi-centre investigation conducted in ten European cities. PARTICIPANTS: 2954 adolescents who were included in the HELENA study and completed the Food Choices and Preferences (FCP) questionnaire. RESULTS: Nineteen out of 124 items of the FCP questionnaire were in the same dimension. Sixteen presented adequate parameters for the Scale of evaluatiOn of Food choIcEs (SOFIE). The scores were positively associated with the intakes of cereals, dairy products, meats and eggs, and fish, as well as with blood concentrations of vitamin C, ß-carotene, n-3 fatty acids, cobalamin, holo-transcobalamin and folate; scores were negatively associated with the intake of alcohol. CONCLUSIONS: SOFIE can improve the assessment of motivation influencing food choices based on items with the best performance and is proposed as a new measure to health-related studies.

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. Exclusion criteria retained items with adequate values of commonality and factor loadings. Estimation of IRT parameters, the Item Characteristic Curve (ICC), and test information guided the selection of the best quality items. The final model adjustment was evaluated using Root Mean Square Error of Approximation (RMSEA), Standardized Root Mean Square Residual (SRMSR), Comparative Fit Index (CFI), and Tucker-Lewis Index (TLI). The eating attitudes on each level of DEAS-s were described. The analyses were performed on R software and Microsoft Excel version 2013. As results, six items were excluded because of the low communalities and factor loadings, and one more was excluded because of an overlapping on the ICC. The remaining 17 items explained 0.53 of the total variance and had an adequate goodness-of-fit (RMSEA = 0.05; SRMSR = 0.05; CFI = 0.98; TLI = 0.98). The information test is more accurate between the scores 0 and +3. Scores higher or equal to 1.5 identified individuals with disordered eating attitudes. Women, older individuals, and those with a higher body mass index presented more disordered eating; thus, the one-dimensional and short version of DEAS showed a suitable adjustment and may contribute to properly evaluate disordered eating in diverse populations.
