- Abstract
Objective: To describe two low-burden diet quality scores and evaluate their performance in reflecting the dietary share of the least and most processed foods defined within the Nova food system classification., Methods: This cross-sectional study included data from the NutriNet-Brasil cohort. Participants answered the Nova24hScreener, a 3-minute self-administered questionnaire measuring the consumption of a set of foods on the day before. Food items included in this tool belong to two main groups of the Nova classification: unprocessed or minimally processed whole plant foods (WPF, 33 items) and ultra-processed foods (UPF, 23 items). Two scores were obtained by summing the number of items checked: the Nova-WPF and the Nova-UPF. We compared the scores, respectively, with the dietary intake (% of total energy) of all unprocessed or minimally processed whole plant foods and all ultra-processed foods obtained from a full self-administered web-based 24-hour recall performed on the same day., Results: The approximate quintiles of each score had a direct and linear relationship with the corresponding % of energy intake (p-value for linear trend < 0.001). We found a substantial agreement between the intervals of each score and the corresponding % of energy intake (Nova-WPF score: Prevalence-Adjusted and Bias-Adjusted Kappa (PABAK) 0.72, 95%CI 0.64-0.81; Nova-UPF score: PABAK 0.79, 95%CI 0.69-0.88)., Conclusions: These two scores performed well against the dietary share of unprocessed or minimally processed whole plant foods and ultra-processed foods in Brazil and can be used to evaluate and monitor diet quality. more...

- Abstract
The objective of this commentary is to describe the characteristics, development and functionalities of the food intake data collection platform QuestNova. The platform was developed by two information technology specialists, with the support of a team from Nupens/USP. The development process took place in stages, with all the functionalities of each step being thoroughly tested by multiple team members before moving on to the next. QuestNova is a free online platform that offers three self-administered instruments for assessing food intake, based on the Nova classification: Screener-Nova, QFA-Nova and R24h-Nova. On the platform, the researcher can select the instrument of interest and send it via a link to the participants in their study, who will answer it autonomously, without the presence of an interviewer. Databases containing relevant indicators for evaluating food according to the level of processing are automatically generated from the responses. A crucial aspect of QuestNova is its commitment to the confidentiality and safety of participant data. No information is stored internally on the platform; on the contrary, data is transmitted directly to a Google Drive account provided by the researcher themselves. QuestNova democratizes access to innovative research tools, boosting studies on the impact of food processing on Brazilian health. Future updates may extend its usefulness. more...

- Abstract
Objective: To assess the prospective association of two diet quality scores based on the Nova food classification with BMI gain., Design: The NutriNet-Brasil cohort is an ongoing web-based prospective study with continuous recruitment of participants aged ≥ 18 years since January 2020. A short 24-h dietary recall screener including 'yes/no' questions about the consumption of whole plant foods (WPF) and ultra-processed foods (UPF) was completed by participants at baseline. The Nova-WPF and the Nova-UPF scores were computed by adding up positive responses regarding the consumption of thirty-three varieties of WPF and twenty-three varieties of UPF, respectively. Participants reported their height at baseline and their weight at both baseline and after approximately 15 months of follow-up. A 15-month BMI (kg/m
2 ) increase of ≥5 % was coded as BMI gain., Setting: Brazil., Participants: 9551 participants from the NutriNet-Brasil cohort., Results: Increasing quintiles of the Nova-UPF score were linearly associated with higher risk of BMI gain (relative risk Q5/Q1 = 1·34; 95 % CI 1·15, 1·56), whereas increasing quintiles of the Nova-WPF score were linearly associated with lower risk (relative risk Q5/Q1 = 0·80; 95 % CI 0·69, 0·94). We identified a moderate inverse correlation between the two scores (-0·33) and a partial mediating effect of the alternative score: 15 % for the total effect of the Nova-UPF score and 25 % for the total effect of the Nova-WPF score., Conclusions: The Nova-UPF and Nova-WPF scores are independently associated with mid-term BMI gain further justifying their use in diet quality monitoring systems. more...- Published

- Abstract
Purpose: The Brazilian Food Guide (BFG)'s messages are mostly qualitative and focused on food practices, such as meal planning, cooking, and eating modes. This study sough to investigate whether the adherence to these food practices is aligned with diet quality., Methods: A quota-based subsample of the NutriNet-Brasil Cohort (n = 2052) completed the Food Practices Brazil Scale (FPBr), a 24-item scale assessing the adherence to healthy eating practices recommended by the BFG. Four possible frequency-based answers are given and a score ranging from 0 to 72 is calculated by summing them (FPBr-score). Data from web-based 24-h recalls were used for calculating the usual percentage of energy intake (%energy) of ten food groups based on the level of food processing: plant-based unprocessed or minimally processed foods; processed foods; ultra-processed foods; fruits; vegetables; whole grains; beans and other legumes; nuts; red meat; and table sugar. The association between quartiles of the FPBr-score and food groups' %energy was analysed through crude and adjusted linear regression models., Results: Except for red meat, all the other food groups were linearly associated with the FPBr-score in the expected direction. For example, adjusted means for the %energy of plant-based unprocessed or minimally processed foods were 26.7% (CI95% 25.9-27.5) and 36.8% (CI95% 36.0-37.6) among those classified in the first and fourth quartiles of the FPBr-score, respectively. For ultra-processed foods, these percentages were 27.0 (CI95% 26.3-27.8) against 17.5 (CI95% 16.7-18.3)., Conclusions: These results support the use of messages based on practices and behaviors in Food-Based Dietary Guidelines. At the same time, they call attention to the importance of policies that enable people to adopt healthier food practices., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Objective: This paper describes the first web-based self-completed 24-h recall designed to categorise food intake according to Nova groups - Nova24h - and its agreement with a reference tool in estimating the dietary relative contribution of the four Nova food groups (% of total energy intake)., Design: Comparisons of estimates of dietary relative contributions of Nova groups obtained by Nova24h and one standard interviewer-led 24-h recall., Setting: Nationwide adult cohort study in Brazil., Participants: The subjects were 186 participants of the NutriNet Brasil Cohort Study ( n 186)., Results: No statistically significant differences were observed between the Nova24h and the reference tool mean contributions of unprocessed or minimally processed foods (52·3 % v . 52·6 %), processed culinary ingredients (11·6 % v . 11·9 %), processed foods (17·1 % v . 14·7 %) and ultra-processed foods (19·0 % v . 20·9 %). Intraclass correlation coefficients between individual estimates obtained for each Nova group showed moderate to good agreement (0·54-0·78). Substantial or almost perfect agreement between the tools was seen regarding the ability to rank participants according to quintiles of contribution of each Nova group (PABAK 0·69-0·81)., Conclusions: Nova24h is a suitable tool for estimating the dietary relative energy contribution of Nova food groups in the NutriNet Brasil cohort. New studies are necessary to verify its adequacy in other populations. more...

- Abstract
This study objective was to describe the distribution of food consumption markers in Brazil per sociodemographic characteristics and its evolution from 2013 to 2019. Healthy food consumption markers (regular consumption of beans, fruits, vegetables, and fish, recommended consumption of red meat, and never replacing meals with snacks) and unhealthy food consumption markers (regular consumption of sweetened beverages and confectionery and excessive salt intake) were studied for adult participants of the Brazilian National Health Survey. The prevalence of food consumption markers was estimated according to sociodemographic characteristics and compared to data of 2013 and 2019. Most of the population regularly consumes beans, fruits, and vegetables, they also follows the recommendation to limit red meat consumption, and never replaces meals with snacks. The percentage of people who regularly consume sweetened beverages and perceive their salt intake as excessive is relatively low. The distribution of food consumption markers was associated with sex, age, income, race/skin color, area of dwelling, and schooling level. From 2013 to 2019, the prevalence of most food consumption markers declined, except for the regular consumption of fruits and recommended consumption of red meat, that increased 8.5% and 18.5%, respectively, and the regular consumption of vegetables, which did not vary. Healthy and unhealthy food consumption markers should be monitored to evaluate the effect of healthy eating policies implemented in the country. more...

- Abstract
Objective: To analyze the convergent validity and invariance of a scale to measure adherence to eating practices recommended by the Dietary Guidelines for the Brazilian Population., Methods: A subsample (n=1309) of the NutriNet-Brasil cohort (self-filled web-based study) answered the 24-items scale based on the Guide, as well as socioeconomic and dietary questionnaires. The score in the scale (eGuia) was compared by Spearman's correlation with scores of fresh and minimally processed foods (eG1) and ultra-processed foods (eG4) consumption, both composed of the average number of food items consumed in three random days. Correlations' direction and strength were observed to infer convergent validity. A multi-group confirmatory factor analysis was used to assess scale invariance at the configural, factorial and metric levels, between subgroups of sex (men/women), age (≤37/>37, being 37 the median) and years of schooling (≤11/>11). The model was invariant when the goodness-of-fit indices varied within acceptable ranges compared to the previous level., Results: Participants were on average 39 years old (sd=13.7), 53% were women and 69% had more than 11 years of education. Correlations between eGuia and eG1, and between eGuia and eG4 were 0.56 and -0.51 (p<0.001), respectively. In all sociodemographic groups, the goodness-of-fit indices varied within acceptable ranges., Conclusion: The correlations show that the eating practices measured by the scale are aligned with a healthy food consumption, showing its convergent validity. In this sample, the scale measured the same dimensions, showed equivalence of items' factor loadings, and generated comparable scores between subgroups of sex, age, and education. more...

- Abstract
This study aimed to develop and validate an instrument to assess Brazilian adults' knowledge, perceptions, and behaviors (KPB) toward salt and sodium. Based on a PAHO/WHO questionnaire, a new instrument was developed and evaluated by 11 experts, generating item and scale-level content validity indexes (I-CVI and S-CVI, respectively). Face validity was verified through a focus group with eight participants, followed by an operational test with 36 interviewees. Exploratory factor analysis (EFA) was used to determine the construct validity, and Cronbach's α coefficient was calculated to analyze instrument's reliability, using data collected via telephone from a probabilistic sample of 422 adults. The generated solutions were analyzed from theoretical and statistical significance perspectives, which supported the determination of the best model. Remaining items were scored, with higher scores related to healthier practices. A descriptive analysis was performed considering the data from the 422-adult sample. I-CVIs (0.73-1), S-CVIs (0.93; 0.97) and the interviewees' analysis indicated that items are representative and clear, in addition to being suitable for application to the target audience. Tests confirmed sample adequacy to perform the EFA (KMO = 0.82; Bartlett's sphericity test, p < .001). The final validated model, with 16 items, sufficiently explained the variance and presented good reliability (Cronbach's α = 0.81; 95% CI 0.79 - 0.84). Women, older individuals, and with higher education had significantly higher scores, regardless of chronic diseases diagnosis (p < .001). This instrument is ready to be applied and easily reproduced, contributing to the assessment of KPB toward salt and sodium in Brazil., (© 2022 The Authors.

- Abstract
This study aims to explore potential barriers and facilitators for healthy eating in the consumer food environment, and to analyze the association with different types of food retailers, having as theoretical reference the Dietary Guidelines for the Brazilian Population. This is a cross-sectional study carried out in the municipality of Jundiaí, São Paulo State, Brazil, with audits of the consumer food environment carried out in 650 retail stores. We identified barriers and facilitators of healthy food choices in the internal environment of the retail. Factor analysis estimated factors that characterized the environment according to barriers and facilitators. Linear regression evaluated the association between the factors and the different categories of establishments. Most establishments had priority sales of ultra-processed products. Out of the total food retailers studied, 75.9% offered sugary drinks; 37% rice, beans and 30% fruits and vegetables. We characterized the first factor by the presence of both barriers and facilitators (mixed factor), the second factor by more facilitators and the third by greater presence of barriers in the consumer environment. Supermarkets were positively associated with the three factors (p-value < 0.001). The fruit and vegetable stores and the neighborhood markets had a positive association with the most facilitating factor (p-value < 0.001). Markets and bakeries were positively associated with the more barriers factor (p-value < 0.001). The patterns that characterize barriers and facilitators for healthy eating differ significantly according to types of food retailers. more...

- Abstract
Objective: This study aimed to develop a conceptual framework of the process of food-based dietary guidelines (FBDG) implementation and analyse Brazil's employed measures to implement dietary guidelines for the Brazilian population (2014)., Design: Qualitative research., Setting: Aiming to develop the conceptual framework, a literature review on FBDG implementation was carried out. Both documents scoped within the macropolitical sphere and scientific articles were reviewed. In the case study, measures took in Brazil were identified through a search on institutional websites and technical management reports of government sectors were responsible for FBDG implementation in the country., Participants: This study does not involve humans., Results: The new conceptual framework frames FBDG implementation as a part of a larger set of intersectoral public policies to promote healthy eating and highlights two main implementation ways: educational materials and public policies. Brazil has a range of policies to promote healthy eating guided by the perspective of food as a right. Most of the implemented measures focussed on the concept of 'FBDG as educational materials,' although the recommendations have also been implemented in public policies., Conclusion: The FBDG implementation should be carried out in an integrated manner with multi-sector involvement. The Brazilian's case analysis can be helpful to decision makers in food policy across the globe be inspired by the Brazilian efforts, considering that the Brazilian FBDG was one of the firsts to have adopted a multidimensional paradigm of healthy eating, including diet sustainability. more...

- Abstract
Objective: To describe the Nova score for the consumption of ultra-processed foods (UPF) and evaluate its potential in reflecting the dietary share of UPF in Brazil., Methods: This study was conducted in São Paulo with a convenience sample of 300 adults. Using a tablet, participants answered a 3-minute electronic self-report questionnaire on the consumption of 23 subgroups of UPF commonly consumed in Brazil, regarding the day prior the survey. Each participant score corresponded to the number of subgroups reported. The dietary share of UPF on the day prior to the survey, expressed as a percentage of total energy intake, was calculated based on data collected on a 30-minute complete 24-hour dietary recall administered by trained nutritionists. The association between the score and the dietary share of UPF was evaluated using linear regression models. The Pabak index was used to assess the agreement in participants' classification according to the fifths of Nova score and the fifths of dietary share of UPF., Results: The average dietary share of UPF increased linearly and significantly with the increase of the Nova score for the consumption of ultra-processed foods. We found a substantial agreement in participants' classification according to the fifths of the distribution of scores and the fifths of the dietary share of UPF (Pabak index = 0.67). Age was inversely associated with a relatively high frequency of UPF consumption (upper fifth of the distribution) for both score and dietary share of UPF., Conclusion: The Nova score for the consumption of ultra-processed foods, obtained in a quick and practical manner, shows a good potential in reflecting the dietary share of UPF in Brazil. more...

- Abstract
The aim of this study was to develop and validate a scoring system, based on AUDITNOVA, to assess the healthiness of the consumer food environment, considering food availability, price, advertising, and placement strategies. Audited data of 650 food retailers were used to develop, validate, and test the consumer food environment healthiness score. To compose the score, the reference was the Dietary Guidelines for the Brazilian Population. The total and subscores were standardized for a scale from 0 to 100. Construct validity was assessed using the Kruskal-Wallis Dunn tests. Cronbach's alpha coefficients were calculated to determine the consistency of the scores. The median score was 33.7 (p25 = 26.9; p75 = 42.1). The public and private specialized indoor fresh food markets showed the highest medians; otherwise, bakeries and food retailers with the predominant sale of ultra-processed foods showed the lowest. The score was able to satisfactorily classify the extreme food retailer groups by the predominant sale of fresh or minimally processed foods and the predominant sale of ultra-processed foods. The results of Cronbach's alpha showed excellent internal consistency (α = 0.91). The score helped to provide an overall assessment of consumer food environment healthiness and was able to classify food retailer groups as healthy and unhealthy according to the degree of processing of the available foods. more...

- Abstract
Objective: To describe the dietary characteristics of participants in the NutriNet Brasil cohort immediately before and during the covid-19 pandemic., Methods: Our data stem from an adult cohort created to prospectively investigate the relationship between diet and morbidity and mortality from chronic non-communicable diseases in Brazil. For this study, we selected the first participants (n = 10,116) who answered twice to a simplified questionnaire on their diet the day before, the first time when entering the study, between January 26 and February 15, 2020, and the second between May 10 and 19, 2020. The questionnaire inquiries about the consumption of healthy (vegetables, fruits and legumes) and unhealthy (ultra-processed foods) eating markers. Comparisons of indicators based on the consumption of these markers before and during the pandemic are presented for the study population and according to gender, age group, macro-region of residence and schooling. Chi-square tests and t-tests were used to compare proportions and means, respectively, adopting p < 0.05 to identify significant differences., Results: For all participants, we found a modest but statistically significant increase in the consumption of healthy eating markers and stability in the consumption of unhealthy food markers. This favorable pattern of dietary changes during the pandemic occurred in most sociodemographic strata. We observed a less favorable changing pattern, with a tendency to increasing consumption of healthy and unhealthy food markers, in the Northeast and North macro-regions and among people with less schooling, suggesting social inequalities in the response to the pandemic., Conclusions: If confirmed, the trend of increased consumption of ultra-processed foods in underdeveloped regions and by people with less schooling is concerning, as eating these foods increases the risk of obesity, hypertension and diabetes, whose presence increases the severity and lethality of covid-19. more...

- Abstract
Objective: To develop and test a scale for healthy eating practices measurement according to the Dietary Guidelines for the Brazilian Population recommendations., Design: Methodological study. The current Brazilian food-based dietary guideline highlights the importance of choosing foods, combining foods to create meals and modes of eating. These recommendations formed the main domains of the scale and served as a basis for the development of ninety-six items, each with a 4-point Likert response option. Content and face validity were tested. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to determine construct validity. Internal consistency was determined using α and ω coefficients, and reproducibility was tested using test-retest., Setting: Brazil.ParticipantsA ten-member expert panel was used to assess content validity. Adults aged 18-60 years were included in the face validity (n 20), EFA (n 352), CFA and reliability tests (n 900)., Results: Of the ninety-six initial items, twenty-four were excluded and fifty-five were reworded following the content and face validations. EFA detected a four-domain structure (Food choices, Modes of eating, Planning and Domestic organization), which explained 41 % of the variance. CFA led to a final twenty-four-item model with acceptable goodness-of-fit indices and good reliability measures (α=0·77; ω=0·83). Intraclass correlation coefficient for the total score (0·82) and analysis of the Bland-Altman plot suggested good reproducibility of the scale., Conclusions: The scale presents good evidence of validity and reliability. This innovative study created a useful tool for evaluation of the impact of the Dietary Guidelines for the Brazilian Population. more...
