<jats:p>Background/Objectives: Adolescents in Latin America are experiencing rising rates of overweight/obesity and non-communicable diseases, while public health nutrition efforts targeting this group remain limited. This study explores adherence to the EAT-Lancet diet and its relationship with micronutrient adequacy and ultra-processed food (UPF) consumption. Methods: Cross-sectional data from national nutrition surveys of 19,601 adolescents across six Latin American countries were analyzed. Data on sociodemographics, anthropometrics, and dietary habits were collected using standardized questionnaires and 24 h dietary recalls or food records. Nutrient intake was estimated via statistical modeling, and nutrient adequacy ratios were based on age- and sex-specific requirements. UPF intake was classified using the NOVA system, and adherence to the EAT-Lancet diet was assessed with the Planetary Health Diet Index. Results: Overall adherence to the EAT-Lancet diet was low (mean score: 28.3%). Rural adolescents had higher adherence than urban adolescents, and those aged 10–13 and 17–19 showed better adherence compared to adolescents aged 14–16. Adolescents from lower socioeconomic backgrounds adhered more than those from higher socioeconomic backgrounds. Adherence varied from 20.2% in Argentina to 30.2% in Brazil and Chile. Higher adherence was associated with lower UPF intake. Among urban adolescents, greater adherence was linked to a higher risk of inadequate riboflavin, niacin, and cobalamin intake, a trend not observed in rural adolescents. Conclusions: Adherence to the EAT-Lancet diet is low among Latin American adolescents, particularly in urban areas. Public health efforts should prioritize reducing UPF consumption, improving access to nutrient-dense, culturally appropriate foods, and supporting fortified staple foods.</jats:p>

<sec> <title>Objetivo.</title> Identificar e compilar os achados de estudos observacionais que analisaram a relação de fatores do ambiente alimentar escolar e individuais de consumo na escola com excesso de peso em escolares da América do Sul no período de 2011 a 2021. </sec> <sec> <title>Métodos.</title> A pesquisa foi realizada em cinco bases de dados (PubMed, Web of Science, SciELO, Scopus e LILACS) e no Google Scholar, além de consulta a especialistas. Foram selecionados estudos observacionais com escolares de 5 a 19 anos, realizados na América do Sul, que usaram medidas objetivas para avaliar excesso de peso, como o índice de massa corporal (Organização Mundial da Saúde e/ou International Obesity Task Force), em associação a fatores do ambiente alimentar escolar e individuais de consumo na escola. O protocolo foi registrado na plataforma PROSPERO (CRD42020212383). </sec> <sec> <title>Resultados.</title> Dos 906 registros identificados, 13 estudos transversais (um da Argentina, um do Equador e 11 do Brasil) foram incluídos na revisão. As prevalências variaram de 7,5% a 32,5% para sobrepeso e 1,7% a 28,0% para obesidade. Fatores do ambiente alimentar escolar, dos domínios político e físico (como educação alimentar e nutricional insatisfatória e indisponibilidade de refeições preparadas na escola) se associaram com maiores prevalências de excesso de peso. Fatores individuais relacionados à adesão ao programa de alimentação escolar (como consumo da alimentação oferecida pela escola ao invés de lanche trazido de casa) se associaram a menores prevalências de excesso de peso. </sec> <sec> <title>Conclusões.</title> São escassos os estudos sul-americanos enfocando a associação entre fatores do ambiente alimentar escolar e/ou individuais e excesso de peso em escolares. As evidências restritas a contextos locais ou regionais incentivam novos estudos de abrangência nacional. </sec>

<jats:p>This study aims to identify the determinants associated to food insecurity in a group of households composed of schoolchildren and their mothers/caregivers, who lived in a low-to-medium community development index area of the city of Santiago, Chile with a high presence of migrant population. The non-probabilistic and convenience sample was made up of 646 people, who answered a series of surveys with the aim of characterizing this group in sociodemographic terms (sex, age, number of inhabitants in the household, place of food purchase, conditional or non-conditional state transfer program beneficiary status, persons in charge of purchasing food for the household, mothers/caregivers education level and basic knowledge of food and nutrition). To assess moderate-to-severe food insecurity and severe food insecurity, the Food Insecurity Experience Scale-FIES was applied between September and October 2021. Logistic regression analysis were used to carry out multivariate analyses, with the use of stepwise back-and-forward strategies for the selected variables and defining <jats:italic>p</jats:italic> &lt; 0.05. These models were adjusted per number of inhabitants in the household. The results indicate that 25.4% of households presented moderate-to-severe food insecurity, and 6.4% severe food insecurity experience. The variables that presented significant odds of risk to food insecurity were being a migrant, low maternal education level, low performance on basic knowledge in nutrition and when the father was responsible for food purchases. Several public policies have been implemented in Chile during the most recent decades aimed at increasing access to healthier foods and the implementation of healthier food environments. Despite this, there are still social and economic health determinants that contribute to the risk of odds insecurity for the most vulnerable groups in the country, thus putting at risk the fulfillment of the human right to adequate food at risk.</jats:p>

<jats:p>Background: There is worldwide interest in measuring local food environments (FEs). The aim of this study was to develop and validate a set of instruments to evaluate FEs in Chile. Methods: Based on the development and validation of four instruments to measure FEs, a literature review, an evaluation by experts, and the implementation of a pilot tool in the FEs of schoolchildren from nine public schools in the commune of Chillán, Chile, were used. Results: A tool to evaluate FEs was provided, based on three dimensions: availability, variety, and advertising of healthy foods. A total of 1928 foods points of purchase were evaluated. The reliability was evaluated by Cronbach’s alpha. Some 74% of the foods’ points of purchase were store locations. The reliability of the four instruments was high to acceptable (store: 0.90; institution: 0.77; street food: 0.74; restaurant: 0.68). Unhealthy foods were highlighted by the scores obtained: store (6.08 ± 4.07; range: 0–13), restaurant (3.95 ± 1.75; range: 0–10), street food (1.18 ± 1.56; range: 0–7), and institution FEs (3.38 ± 2.78; range: 0–9). Conclusions: The results of this tool can provide information to governments for incorporating structural measures to ensure adequate availability, variety, and advertising of healthy foods in different FEs.</jats:p>
