[Body image dissatisfaction and low adherence to the Western dietary standard among schoolchildren: a cross-sectional study]. / Insatisfação com a imagem corporal e baixa aderência ao padrão alimentar ocidental em escolares: um estudo transversal.

This study aimed to identify dietary patterns and to evaluate the association between body image perception and these patterns among schoolchildren. A cross-sectional study was conducted on 385 schoolchildren (both sexes, 10-17 years old) from four public schools in Salvador, Brazil. Two non-consecutive 24-hour dietary recalls were applied, and the dietary pattern was determined by Exploratory Factor Analysis after adjustment of dietary data using the Multiple Source Method. To evaluate body image perception, the Brazilian body shape silhouette was used. The associations between body image perception and dietary patterns using the polytomous logistic regression model adjusted for covariables was assessed. Three dietary patterns were obtained: "Western standard," unhealthy, "healthy pattern" and "typical dishes/ junk food." After adjustment, adolescents who wished for a slimmer silhouette (2.48 [95%CI: 1.04-6.11], 3.49 [95%CI: 1.35-9.05] and 2.87 [95%CI: 1.13-7.26]) were more likely to adhere to the quintiles with the lowest consumption of the Western standard, compared to those satisfied with their body image. No associations were identified in the other two dietary patterns. Adolescents dissatisfied with their bodies tend to adhere less to unhealthy dietary patterns.

Um estudo transversal foi conduzido em 385 escolares (ambos os sexos, 10-17 anos de idade) de 4 escolas públicas de Salvador, Brasil. Dois recordatórios alimentares de 24h não consecutivos foram aplicados e o padrão alimentar foi determinado por Análise Fatorial Exploratória, após ajuste dos dados dietéticos pelo Multiple Source Method. Para avaliar percepção da imagem corporal, nós usamos uma escala brasileira de silhuetas. Avaliamos as associações entre percepção da imagem corporal e padrões alimentares usando o modelo de regressão logística politômica ajustado para covariáveis. Três padrões alimentares foram obtidos: "padrão ocidental", "padrão saudável" e "comidas típicas/junk food". Após ajuste, adolescentes que desejavam uma silhueta menor (2,48 [IC95%: 1,04-6,11], 3,49 [IC95%: 1,35-9,05] e 2,87 [IC95%: 1,13-7,26]) tinham mais chances de aderir aos quintis de menor consumo do padrão ocidental, comparados àqueles satisfeitos com sua imagem corporal. Nenhuma associação foi identificada nos outros dois padrões alimentares. Adolescentes insatisfeitos com seus corpos tendem a aderir menos a padrões alimentares não saudáveis.

Habits and Persistent Food Restriction in Patients with Anorexia Nervosa: A Scoping Review.

The aetiology of anorexia nervosa (AN) presents a puzzle for researchers. Recent research has sought to understand the behavioural and neural mechanisms of these patients' persistent choice of calorie restriction. This scoping review aims to map the literature on the contribution of habit-based learning to food restriction in AN. PRISMA-ScR guidelines were adopted. The search strategy was applied to seven databases and to grey literature. A total of 35 studies were included in this review. The results indicate that the habit-based learning model has gained substantial attention in current research, employing neuroimaging methods, scales, and behavioural techniques. Food choices were strongly associated with dorsal striatum activity, and habitual food restriction based on the self-report restriction index was associated with clinical impairment in people chronically ill with restricting AN. High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) and Regulating Emotions and Changing Habits (REaCH) have emerged as potential treatments. Future research should employ longitudinal studies to investigate the time required for habit-based learning and analyse how developmental status, such as adolescence, influences the role of habits in the progression and severity of diet-related illnesses. Ultimately, seeking effective strategies to modify persistent dietary restrictions controlled by habits remains essential.

Association between Socioeconomic Factors, Food Insecurity, and Dietary Patterns of Adolescents: A Latent Class Analysis.

Socioeconomic factors and food insecurity play a fundamental role in the food choices of adolescents, and in addition to influencing access to food, they also have significant effects on dietary patterns. The objectives of this study were to identify the dietary patterns of adolescents through the application of latent class analysis and to evaluate their association with socioeconomic variables and food insecurity. This cross-sectional study was conducted with adolescents aged between 11 and 17 years from public schools. Latent class analysis was used to identify the dietary patterns. Associations between socioeconomic factors, food insecurity and dietary patterns were assessed using multinomial logistic regression (odds ratio (OR); 95% confidence interval (CI)). Among the 1215 participants in the study, four dietary patterns were identified: "Mixed", "Low consumption", "Prudent" and "Diverse". A "Diverse" dietary pattern was associated with a lower economic stratum (OR:2.02; CI:1.26-3.24). There was no association between food insecurity and identified dietary patterns. These results highlight the importance of promoting healthy eating in this age group at all socioeconomic levels, especially the lowest level.

Weight stigma and disordered eating behaviors during the COVID-19 pandemic: the mediating role of weight gain concern and psychological distress.

OBJECTIVES: The purpose of this study is to investigate whether the relationship between weight stigma experiences and disordered eating behaviors during the COVID-19 pandemic is mediated by weight gain concern and psychological distress among university students with and without overweight. METHODS: A cross-sectional study was conducted with university students from five regions of Brazil who participated in the baseline assessment of the Online Cohort on Eating Behavior and Health (July/August 2020). Information on the frequency of binge eating episodes, food restriction, and purging, as well as experienced weight stigma, weight gain concern, and psychological distress, were recorded in an online questionnaire. Stratified structural equation modeling (SEM) analyses were performed to address the research questions of interest. RESULTS: Out of the total sample (n = 2511), 33.5% of participants reported experiencing weight stigma. The prevalence of binge eating episodes, food restriction, and purging was 43.7%, 24.1%, and 5.4%, respectively. These behaviors were more prevalent in individuals with overweight than in those without this condition. Furthermore, it was observed that weight gain concern and psychological distress mediated the relationship between weight stigma and disordered eating behaviors regardless of body weight status. CONCLUSIONS: Experiences of weight stigma and disordered eating behaviors were prevalent among Brazilian university students, especially among those with overweight. Weight gain concern and psychological distress appear to be important factors underlying the relationship between these constructs during the pandemic, and they can contribute to the development of targeted strategies for the prevention and management of disordered eating. LEVEL OF EVIDENCE: Level V, cross-sectional study.

Factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil: a hierarchical approach.

The objective of this article is to identify the prevalence and evaluate the factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil. Cross-sectional study with 2,439 adolescents from Sample 2 (2015) of the National School-based Health Survey. Extreme weight loss behaviors, such as self-induced vomiting, laxative use and use of medicines or formulas (outcome) and independent variables were evaluated using a self-administered electronic questionnaire. The statistical analysis was performed following a hierarchical conceptual model. The prevalence of extreme weight loss behaviors in the sample was 12.1%. Among the factors that showed significant association with the outcome, we emphasize the administration model of the private school (PR = 0.62; CI = 0.46-0.84), bullying related to body appearance and for other reasons (PR = 1.62; CI = 1.19-2.20), forced sexual intercourse (PR = 2.65; CI = 1.90-3.69), insomnia (PR = 1.84; CI = 1.43-2.37), and be perceived as fat or very fat (PR = 1.90; CI = 1.50-2.42). Moderate prevalence of extreme weight loss behaviors was identified among adolescents. Socioeconomic factors, exposure to violence, mental health, and body image were associated with the adoption of these behaviors.

Estudo transversal com 2.439 adolescentes da Amostra 2 (2015) da Pesquisa Nacional de Saúde do Escolar. Os comportamentos extremos para perda de peso (desfecho) e as variáveis independentes foram avaliadas por meio de um questionário eletrônico autoaplicável. A análise estatística foi realizada seguindo um modelo conceitual hierárquico. A prevalência de comportamentos extremos para perda de peso na amostra foi de 12,1%. Entre os fatores que mostraram associação significativa com o desfecho, destacam-se a situação administrativa da escola privada (RP = 0,62; IC = 0,46-0,84), ser vítima bullying relacionado à aparência corporal e pelos demais motivos (RP = 1,62; IC = 1,19-2,20), ser forçado a ter relação sexual (RP = 2,65; IC = 1,90-3,69), ter insônia (RP = 1,84; IC = 1,43-2,37) e se autoperceber como gordo ou muito gordo (RP = 1,90; IC = 1,50-2,42). Prevalência moderada de comportamentos extremos para perda de peso foi identificada entre os adolescentes. Os fatores socioeconômicos, de exposição à violência, de saúde mental e da imagem corporal se associaram à adoção de tais comportamentos.

Global, regional and national prevalence of copper, selenium and zinc deficiencies in women of childbearing age: protocol for systematic review and meta-analysis.

INTRODUCTION: Micronutrient deficiencies are common in low-income and middle-income countries and are usually related to inadequate food intake, poor diet quality and low bioavailability. Copper, selenium and zinc are essential minerals in several enzymatic reactions and their deficiencies are associated with worse prognosis in pregnancy, compromising maternal health as well as her offspring. Thus, the objective of the present systematic review will be to describe the prevalence of copper, selenium and zinc deficiencies in women of childbearing age. METHODS AND ANALYSIS: The search will be performed by independent reviewers. The bases used will be PubMed/MEDLINE, Science direct, Lilacs, Adolec, Scopus, EMBASE, CINAHL, Web of Science, CENTRAL, IMSEAR, PAHOS, WPRIM, IMEMR, AIM for grey literature OpenGrey and OVID. National data will be searched in BDTD. A first search will be performed and a second search will be performed just before submission. Risk of bias assessment will be performed using the Joanna Briggs group prevalence study checklist. Combinable studies will be performed meta-analysis. Heterogeneity will be tested using Cochran's Q test and quantified by the inconsistency test (I²). In the presence of high heterogeneity, meta-analysis will be performed using the random effects model with Stata metaprop. Summary prevalence will be generated for each outcome, presented in Forest plot figures. ETHICS AND DISSEMINATION: This systematic review will be solely based on published and retrievable literature, no ethics approval will be obtained. Our dissemination strategy will involve the presentation in scientific meetings, as well as the publication of article(s), posters and presentations in congresses.

[Body image is associated with anthropometric status in adolescents, but not with lifestyle]. / Imagem corporal está associada com estado antropométrico em adolescentes, mas não com estilo de vida.

Body image is a construct of the multifaceted representation of body identity that involves self-perception, beliefs, attitudes about the body itself, which can be influenced by several factors. This study evaluated the association of body image with anthropometric and lifestyle indicators among adolescents. The sample comprised 465 adolescents aged 10 to 17 years from public schools in the city of Salvador-Bahia. The Silhouettes Scale assessed the body image. The anthropometric data (body mass index and waist circumference), the lifestyle (Physical Activity Questionnaire for Adolescents and television time), economic and demographic data were evaluated. Polytomous logistic regression assessed associations of interest by STATA, version 16.0. Overweight (OR:9,7; CI95%:5,4-17,5) and abdominal obesity (OR:14,0; CI95%: 5,0-39,3) were positively associated with body dissatisfaction. However, there was no association with lifestyle variables (physical activity: OR: 1,7, CI: 0,9-2,9, and TV time: OR:1,2; CI:0,8-1,9). The conclusion reached is that anthropometric status is an essential indicator of adverse body image outcomes in adolescents.

A imagem corporal é um constructo da representação multifacetada da identidade corporal, envolve autopercepção, crenças e atitudes sobre o próprio corpo, podendo ser influenciada por diversos fatores. Este estudo avaliou a associação da imagem corporal com indicadores antropométricos e do estilo de vida em adolescentes. Constituíram a amostra 465 adolescentes de 10 a 17 anos de escolas públicas da cidade de Salvador, na Bahia. A imagem corporal foi avaliada pela Escala de Silhuetas. Os dados antropométricos (índice de massa corporal e a circunferência da cintura), de estilo de vida (Physical Activity Questionnaire for Adolescents e o tempo de televisão), econômicos e demográficos foram avaliados. Regressão logística politômica avaliou as associações de interesse. Os dados foram analisados pelo software STATA, versão 16.0. O sobrepeso/obesidade (OR: 9,7; IC95%: 5,4-17,5) e a obesidade abdominal (OR: 14,0; IC95%: 5,0-39,3) se mostraram positivamente associados à insatisfação corporal, mas não foi observada associação com as variáveis de estilo de vida (atividade física: OR: 1,7; IC95%: 0,9-2,9; e tempo de TV: OR: 1,2; IC95%: 0,8-1,9). Conclui-se que o estado antropométrico é um importante indicador dos desfechos negativos da imagem corporal em adolescentes.

Uma análise das representações sociais da obesidade por profissionais de saúde na atenção primária à saúde / An analysis of social representations of obesity by health professionals in primary health care

Introdução: A compreensão do que seja obesidade vai influenciar a maneira como estruturamos as políticas públicas, o processo formativo dos profissionais de saúde e, principalmente, as práticas de cuidado. Objetivo: Analisar as representações sociais sobre obesidade para profissionais de saúde da Atenção Primária do estado da Bahia, Brasil. Método: Esta comunicação breve refere-se a uma pesquisa qualitativa, ancorada na Teoria das Representações Sociais, desenvolvida no contexto de um curso sobre a qualificação do cuidado às pessoas com sobrepeso e obesidade. Para a produção dos dados, utilizaram-se um questionário semiestruturado on-line e a Técnica de Associação Livre de Palavras, a partir do estímulo "Escreva as três primeiras palavras que vêm a sua mente quando você pensa em obesidade". A análise prototípica foi realizada com a ajuda do software OpenEvoc. Resultados: Os resultados indicam que o núcleo central das representações sociais sobre obesidade foi formado pelos elementos doença, alimentação, sobrepeso e gordura, enquanto os vocábulos saúde mental, qualidade de vida, atividade física, estigma, saúde e multifatorialidade compõem o sistema periférico. Revelaram que há predominância da perspectiva patológica e individualizada, em que pesem a ampliação do conhecimento científico moderno e das orientações institucionais sobre a obesidade; a assunção dos fatores psicoemocionais no desenvolvimento da obesidade; assim como a incipiência da abordagem multifatorial, ecológica e/ou sindêmica da obesidade. Conclusão: Este estudo sugere que pesquisas aprofundem o estudo de tais representações sociais, suas motivações no campo formativo, laboral e social, bem como a análise do que consolida e provoca as novas narrativas anunciadas.

Introduction: The understanding of whatobesity is will influence the way we structure public policies, the training process of health professionals, and, mainly, care practices. Objective: To analyze the social representations of obesity among Primary Health Care professionals in the state of Bahia, Brazil. Method: This brief communication refers to qualitative research, anchored in the Theory of Social Representations, developed in the context of a course on the qualification of care for people with overweight and obesity. For data production, we used an online semi-structured questionnaire and the Free Word Association Technique, based on the stimulus "Write the first three words that come to your mind when you think about obesity". The prototypical analysis was carried out with the assistance of the OpenEvoc software. Results: The results indicate that the central core of social representations about obesity was formed by the elements disease, food, overweight and fat, while the words mental health, quality of life, physical activity, stigma, health, and multifactorial constitute the peripheral system. They revealed that the pathological and individualized perspective is predominant, despite the enhancement of modern scientific knowledge and institutional guidelines on obesity; the assumption of psycho-emotional factors in the development of obesity; as well as the incipience of the multifactorial, ecological, and/or syndemic approach to obesity. Conclusion: This study suggests that research deepens the study of such social representations, and their motivations in the educational, labor, and social field, like the analysis of what consolidates and provokes the newly announced narratives.

Permanent health education in the context of obesity: a scoping review

ABSTRACT OBJETIVE To map the international literature on Permanent Health Education initiatives to care for people with obesity. METHODS In total, six databases were searched without any language or publication period restriction according to the Joana Briggs Institute manual for evidence synthesis and the Prisma extension for scoping reviews (Prisma-ScR). Articles were independently analyzed by four reviewers and data, by two authors, which were then analyzed and discussed with our research team. RESULTS After screening 8,780 titles/abstracts and 26 full texts, 10studies met our eligibility criteria. We extracted data on methodologies, themes, definitions of obesity, outcomes, and gaps. Most initiatives came from North American countries without free or universal health systems and lasted a short period of time (70%), had multidisciplinary teams (70%), and addressed sub-themes on obesity approaches (90%). Results included changes in participants' understanding, attitude, and procedures (80%) and gaps which pointed to the sustainability of these changes (80%). CONCLUSION This review shows the scarce research in the area and a general design of poorly effective initiatives, with traditional teaching methodologies based on information transmission techniques, the understanding of obesity as a disease and a public health problem, punctual actions, disciplinary fragmentation alien to the daily work centrality, and failure to recognize problems and territory as knowledge triggers and to focus on health care networks, line of care, the integrality of care, and food and body cultures.

Imagem corporal e autoestima em adolescentes da rede pública estadual de Salvador-Bahia / Imagen corporal y autoestima en adolescentes de la red pública estatal de Salvador-Bahía / Body image and self-esteem in adolescents from the state public network of Salvador-Bahia

RESUMO. Objetivo: Analisar a associação entre insatisfação com a imagem corporal e autoestima de adolescentes matriculados na rede pública estadual de ensino fundamental em Salvador-Bahia. Método: Participaram deste estudo de corte transversal 860 adolescentes de 10 a 19 anos de idade, de ambos os sexos, matriculados do 7º sétimo ao 9º nono ano em 12 escolas de médio porte da rede pública estadual do ensino fundamental em turno integral, do município de Salvador, Bahia. A autoestima foi avaliada por meio da Escala de Autoestima de Rosenberg e a insatisfação com a imagem corporal pelo Body Shape Questionnaire. Dados demográficos e socioeconômicos, maturação sexual, estado antropométrico, nível de atividade física e sedentarismo foram também avaliados. A associação entre insatisfação com a imagem corporal e autoestima foi analisada pela regressão multinominal para variáveis politômicas utilizando o programa estatístico SPSS, versão 23.0. Resultados: Entre os adolescentes, 24,8% tinham moderada autoestima e 27,3% apresentaram os menores escores desse constructo. A insatisfação com a imagem corporal foi identificada em 25,2% dos adolescentes. A análise de associação revelou que adolescentes com insatisfação com a imagem corporal possuem 5,61 (IC 95% 3,08-10,24) vezes maior chance em manifestar baixa autoestima para o sexo feminino e 3,83 (IC 95% 2,03-7,25) vezes para o sexo masculino. Ainda entre as meninas, a insatisfação com a imagem corporal permaneceu associada positivamente à moderada autoestima após ajuste do modelo (OR: 2,31; IC 95% 1,21-4,41). Conclusão: Foi observada alta prevalência de níveis baixos e moderados de autoestima e que a insatisfação com a imagem corporal influenciou a baixa autoestima em ambos os sexos e a moderada entre as meninas.

ABSTRACT. Objective: To analyze an association between dissatisfaction with body image and self - esteem of adolescents enrolled in the public elementary school system in Salvador - Bahia. Methods: Participated in this cross-sectional study 860 adolescents aged 10 to 19, of both sexes from the 7th to the 9th year, enrolled in twelve medium-sized schools of the public elementary school system in full shift, in the city of Salvador, Bahia. Self-esteem was assessed through the Rosenberg Self-esteem Scale and body image dissatisfaction by the Body Shape Questionnaire. Demographic and socioeconomic data, sexual maturation, anthropometric status, physical activity level and sedentary lifestyle were evaluated.

Results: Among the adolescents, 24.8% had moderate self-esteem and 27.3% had the lowest scores of this construct. Body image dissatisfaction was identified in 25.2% of the adolescents. The association analysis revealed that adolescents with body image dissatisfaction have 5.61 (95%ci 3.08-10.24) times greater chance of manifesting low self-esteem for females and 3.83 (95%ci 2.03-7.25) times for males. Still among girls, dissatisfaction with body image remained positively associated with moderate self-esteem after adjusting the model (OR: 2.31; 95%ci 1.21-4.41). Conclusion: It was concluded that the prevalence of low and moderate self-esteem was high, and dissatisfaction with body image influenced low self-esteem in both sexes and a moderate among girls.

Effects of computer-based interventions on food consumption and anthropometric parameters of adolescents: A systematic review and metanalysis.

This review aimed to systematically assess the effects of computer-based interventions for the promotion of healthy eating on anthropometric indicators and food consumption of adolescents at school. Relevant scientific articles were searched in MEDLINE/PubMed, Embase, Scopus, Lilacs, PsycINFO and Cochrane Library/CENTRAL following the recommendations by PRISMA guide in August 2021. The quality and risk of bias in the studies were assessed by two reviewers independently. The search strategy retained 13 studies for qualitative analysis. In total 9.603 adolescents of both sexes, were recruited in a school environment. According to studies with information for the meta-analysis, a reduction in the average consumption of fats in favor of computer-based intervention was identified (SMD: -0.14; 95% CI -0.24;-0.05). Considering the changes in the consumption of fruits and vegetables (SMD: 0.09; 95% CI -0.08; 0.26) and in the BMI (WMD: -0.02; 95% CI -0.18; 0.14), the analyses did not identify the effect of computer-based interventions on these parameters after follow-up. The results of this review demonstrate that there is evidence of the positive effect of using digital technology (website and CD-ROM) in educational programs with a focus on promoting a healthy lifestyle, with evidence on reducing fat consumption.

Variação temporal da ocorrência do excesso de peso e da obesidade abdominal em adolescentes da cidade de Salvador, Bahia, Brasil / Temporal variation in the incidence of overweight and abdominal obesity among adolescents in the city of Salvador, Bahia, Brazil

Resumo O objetivo do estudo foi analisar a variação temporal da ocorrência do excesso de peso e da obesidade abdominal em adolescentes de escolas públicas de uma capital do nordeste brasileiro. Trata-se de um estudo incluindo informações de três levantamentos transversais realizados nos anos de 2001, 2009 e 2017, com 2.496 escolares de 10 a 18 anos de ambos os sexos, residentes na cidade de Salvador, Bahia. O excesso de peso foi avaliado por meio do Índice de Massa Corpórea para idade (IMC/I) e obesidade abdominal foi avaliada pela circunferência da cintura e razão cintura-estatura. A regressão Pooled OLS (Ordinary Least Squares), de efeito constante foi utilizada para avaliar a variação dos indicadores antropométricos ao longo do período. Os resultados deste estudo indicam que a prevalência de excesso de peso cresceu 103% e os indicadores da obesidade abdominal cresceram 153% e 142%, respectivamente no período analisado. Aumento na média do Índice de Massa Corpórea e da Razão cintura estatura foi maior entre as adolescentes e da média do IMC e da circunferência da cintura entre aqueles de 14 a 18 anos de idade. Conclui-se que houve expressivo crescimento nas prevalências do excesso de peso e da obesidade abdominal no período de 2001 a 2017 entre os adolescentes da cidade de Salvador.

Abstract The scope of this study was to analyze the temporal variation in the incidence of overweight and abdominal obesity among adolescents from public schools in a capital in northeastern Brazil. It is a study including information from three cross-sectional surveys carried out in 2001, 2009 and 2017, with 2,496 students aged 10 to 18 years of both sexes living in the city of Salvador, Bahia. Overweight was assessed using the Body Mass Index for Age (BMI/A) and abdominal obesity was assessed using waist circumference and waist-to-height ratio. Pooled OLS (Ordinary Least Squares) regression, with constant effect, was used to assess the variation of anthropometric indicators over the period. The results of this study indicate that the prevalence of overweight increased by 103% and the indicators of abdominal obesity increased by 153% and 142%, respectively, in the period under analysis. The increase in the mean body mass index and waist-to-height ratio was greater among adolescents and in the mean BMI and waist circumference among those aged 14 to 18 years old. The conclusion reached was that there was a significant increase in the prevalence of overweight and abdominal obesity in the period 2001 to 2017 among adolescents in the city of Salvador.

Degree of food processing and association with overweight and abdominal obesity in adolescents.

OBJECTIVE: To evaluate the association between the degree of food processing, overweight, and abdominal obesity in adolescents. METHODS: This is a cross-sectional study, with 576 adolescents aged 10 to 17 years, of both sexes. Food consumption was collected using the Food Frequency Questionnaire and foods classified as in natura or minimally processed, processed foods associated with culinary ingredients, and ultraprocessed foods. Sociodemographic data, body mass index, waist circumference and waist-to-height ratio were collected. The analysis was evaluated by the Mann-Whitney test and prevalence ratio with 95% confidence interval, considering p<0.05. RESULTS: An intake above the third quartile of processed foods associated with culinary ingredients (prevalence ratio of 1.64; 95%CI: 1.12-2.42) and ultraprocessed (prevalence ratio of 1.58; 95%CI: 1.07-2.34) was associated with a higher prevalence of overweight. Consumption above the third quartile of ultraprocessed foods was associated with a higher prevalence of abdominal obesity, assessed by waist circumference (prevalence ratio of 2.48; 95%CI: 1.41-4.36), and waist-height ratio (prevalence ratio of 2.09; 95%CI: 1.11-3.92). CONCLUSION: A higher consumption of processed foods associated with culinary ingredients was related to being overweight, and ultraprocessed foods with overweight and abdominal obesity.
