Temporal trend in the nutritional status of children in a Brazilian metropolis in light of food and nutrition policies / Tendencia temporal en el estado nutricional de los niños en una metrópolis brasileña a la luz de las políticas de alimentación y nutrición

Introduction. Brazil's health system offers insights into addressing the double burden of malnutrition by proper population monitoring, coupled with local policies and national guidelines. Objective. To investigate the recent temporal trends in nutritional status indicators and its coverage of children aged two to five years from Campinas, a metropolis in the state of São Paulo, Brazil. Material and methods. The analysis of time series from 2018 to 2022 were conducted by accessing data from the Brazilian Food and Nutrition Surveillance System (SISVAN) due to regression analysis. Results. The number of children aged two to five in the SISVAN registry rose from 7,300 in 2018 to 11,171 in 2022, forming the study sample. In 2018, 700 were chronically undernourished, 306 underweight, and 977 overweight; by 2022, 530 showed stunting, 457 were underweight, and 1,084 overweight. Stunting prevalence declined from 9.6% (2018) to 4.7% (2022). Underweight dropped slightly from 4.2% to 4.1% over the years and overweight, consistently the highest indicator, ranged from 13.4% (2018) to 9.7% (2022). SISVAN's coverage varied between 16.6% (2018) and 26.1% (2022), the lowest at 12.3% in 2020. The trend for stunting decreased significantly (APV: -15.01; CI95% -22.64; -6.62). Adding SISVAN's coverage variable the model slightly reduced the declining stunting trend (APV: -12.12; CI95% -13.19; -11.04). Conclusions. Coordinated efforts to address nutritional challenges, from adequate population monitoring to the interaction between local policies and national guidelines, have shown positive health outcomes(AU)

Introducción. El sistema de salud de Brasil ofrece conocimientos valiosos para abordar la doble carga de malnutrición mediante el seguimiento adecuado de la población y políticas locales y nacionales. Objetivo. Investigar las tendencias temporales recientes en indicadores nutricionales y cobertura en niños de dos a cinco años en Campinas, São Paulo, Brasil. Materiales y métodos. Se analizaron datos del SISVAN de 2018 a 2022 con regresión temporal. Resultados. Niños de dos a cinco años en el SISVAN pasaron de 7,300 en 2018 a 11,171 en 2022. En 2018, 700 estaban crónicamente desnutridos, 306 con bajo peso y 977 con sobrepeso; en 2022, 530 con retraso en el crecimiento, 457 con bajo peso y 1,084 con sobrepeso. La prevalencia del retraso en el crecimiento bajó de 9,6% a 4,7%. El bajo peso disminuyó levemente del 4,2% al 4,1% y el sobrepeso osciló del 13,4% al 9,7%. La cobertura de SISVAN varió de 16.6% a 26.1%, con un mínimo de 12.3% en 2020. La tendencia del retraso en el crecimiento disminuyó significativamente (APV: -15.01; CI95% -22.64; -6.62). La inclusión de la cobertura de SISVAN redujo levemente esta tendencia (APV: -12.12; CI95% -13.19; -11.04). Conclusiones. Coordinar esfuerzos para abordar los desafíos nutricionales, desde el seguimiento de la población hasta políticas locales y nacionales, ha tenido resultados positivos para la salud(AU)

Relationship between food environment, social isolation and diet quality in Brazil / Relación entre el entorno alimentario, el aislamiento social y calidad de la dieta en Brasil. Introducción

Introduction. The COVID-19 pandemic has impacted diet quality in differentways. In this context, community, organizational and consumer nutrition environments can influence the eating pattern. Objective. The purpose of this study was to identify how quarantine during the COVID-19 pandemic changed the diet in Brazil. Materials and methods. A natural experiment organized into experimental (social-isolated group - SIG) and control groups (non-isolated group - CG) was conducted with data collection from an online survey at the beginning of the pandemic (T0) and in the less restrictive period of 2020 (T1). Pre-post improvements in diet quality (IDQ) were determined for the SIG and CG. Intro-intergroup changes were tested using the Mann­Whitney and Wilcoxon signed rank tests. The intervention effect was estimated using crude and adjusted difference- indifference in multilevel regression analysis accounting for repeated measures. Results. A sample of 565 Brazilian adults answered the questionnaire at T0 and T1. IDQ was favored twice or more by attitudes such as buying food directly from farmers/street markets, reducing requests for food delivery, and increasing time spent on eating activities and the frequency of cooking. The isolated group had no IDQ at T1, whereas the no isolated group, who worsened diet quality (6.1%) at T0, improved it at T1 (4.8%). Conclusions. The restrictive quarantine forced the non-isolated population to have an experience comparable to a food desert, negatively affecting their diet(AU)

COVID-19 ha impactado la calidad de la dieta de diferentes maneras. Los entornos comunitarios, organizacionales y nutricionales de los consumidores pueden influir en los patrones dietéticos. Objetivo. el objetivo de este estudio fue identificar cómo la cuarentena durante la pandemia de COVID-19 cambió la dieta en Brasil. Materiales y métodos. Se realizó un experimento natural organizado en grupos experimental (grupo socialmente aislado - SIG) y control (grupo no aislado - GC) con datos recolectados en una encuesta en línea al inicio de la pandemia (T0) y en el momento menos restrictivo de 2020 (T1). Se determinaron mejoras pre-post en la calidad de la dieta (IDQ) para SIG y GC. Los cambios intra-intergrupo se probaron utilizando las pruebas de rangos con signos de Mann-Whitney y Wilcoxon. El efecto de la intervención se estimó utilizando diferencias crudas y ajustadas en el análisis de regresión multinivel, teniendo en cuenta medidas repetidas. Resultados. Una muestra de 565 adultos brasileños respondió el cuestionario en T0 y T1. IDQ se vio favorecido dos o más veces por actitudes como comprar alimentos directamente de los agricultores/mercados callejeros, reducir los pedidos de entrega de alimentos y aumentar el tiempo dedicado a las actividades alimentarias y la frecuencia de cocinar. El grupo aislado no mostró IDQ en T1, mientras que el grupo no aislado, que tenía peor calidad de la dieta (6,1%) en T0, mejoró en T1 (4,8%). Conclusiones. La cuarentena restrictiva obligó a la población no aislada a tener una experiencia comparable a un desierto alimentario, afectando negativamente su dieta(AU)

Identifying and Estimating Ultraprocessed Food Intake in the US NHANES According to the Nova Classification System of Food Processing.

BACKGROUND: The degree of food processing may be an important dimension of diet in how it relates to health outcomes. A major challenge is standardizing food processing classification systems for commonly used datasets. OBJECTIVES: To standardize and increase transparency in its application, we describe the approach used to classify foods and beverages according to the Nova food processing classification in the 24-h dietary recalls from the 2001-2018 cycles of What We Eat in America (WWEIA), NHANES, and investigate variability and potential for Nova misclassification within WWEIA, NHANES 2017-2018 data via various sensitivity analyses. METHODS: First, we described how the Nova classification system was applied to the 2001-2018 WWEIA, NHANES data using the reference approach. Second, we calculated the percentage energy from Nova groups [1: unprocessed or minimally processed foods, 2: processed culinary ingredients, 3: processed foods, and 4: ultraprocessed foods (UPFs)] for the reference approach using day 1 dietary recall data from non-breastfed participants aged ≥1 y from the 2017-2018 WWEIA, NHANES. We then conducted 4 sensitivity analyses comparing potential alternative approaches (e.g., opting for more vs. less degree of processing for ambiguous items) to the reference approach, to assess how estimates differed. RESULTS: The energy contribution of UPFs using the reference approach was 58.2% ± 0.9% of the total energy; unprocessed or minimally processed foods contributed 27.6% ± 0.7%, processed culinary ingredients contributed 5.2% ± 0.1%, and processed foods contributed 9.0% ± 0.3%. In sensitivity analyses, the dietary energy contribution of UPFs ranged from 53.4% ± 0.8% to 60.1% ± 0.8% across alternative approaches. CONCLUSIONS: We present a reference approach for applying the Nova classification system to WWEIA, NHANES 2001-2018 data to promote standardization and comparability of future research. Alternative approaches are also described, with total energy from UPFs differing by ∼6% between approaches for 2017-2018 WWEIA, NHANES.
