Publication Effects of school closure on lifestyle behaviours and health outcomes in children during the COVID-19 pandemic in Chile: A time-matched analysis(2024) SuĆ”rez, MĆ³nica; FernĆ”ndez, Rodrigo; Quintiliano Scarpelli Dourado, Daiana; Pinheiro Fernandes, Anna Christina; Pizarro, TitoBackground: The COVID-19 pandemic led to school closures, potentially impairing children's behaviours and health. We aimed to explore the effects of school closure on lifestyle behaviours (dietary habits, physical activity) and health outcomes (adiposity, fitness, self-esteem, self-concept) in children. Methods: We measured 247 children before school closure (October-November 2019) and after school reopening (October-November 2021) (COVID-19 group). To distinguish the changes due to school closure from changes due to growth, we included 655 age-matched children with cross-sectional measurements in October-November 2019 (control group). The response of this group (i.e., differences between children with 2 years of difference) was considered the expected response to growth. Two-way ANOVA was used to test age-by-group interactions, indicating an effect of school closure. Results: In 7-to-9-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.4 points), resulting in higher physical inactivity prevalence (by 19 percent points) at 9 years. This was accompanied by larger-than-expected increases in fat percentage (by 6.1 percent point). In 8-to-10-year-old children, the COVID-19 group had higher physical inactivity prevalence at 10 years (by 20 percent points). This was accompanied by larger-than-expected increases in fat percentage (by 8.3 percent points), z-score BMI (by 0.90 units), and waist circumference (by 6.1 cm). In 9-to-11-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.3 points) and increases in self-concept (by 0.2 points). The response in dietary habits, fitness, or self-esteem was not different between groups. Conclusion: Overall, school closure negatively impacted physical activity and adiposity, particularly in the youngest children.Publication Diet quality of Chilean schoolchildren: How is it linked to adherence to dietary guidelines?(2025) Pinheiro Fernandes, Anna Christina; Araneda Flores, Jacqueline; Quintiliano Scarpelli Dourado, Daiana; Pizarro Quevedo, Tito; Marques de Oliveira, MarĆa RitaIntroduction In Chile, the prevalence of overweight among schoolchildren over the age of 5 is approximately 50%, one of the highest in the Americas region. This is largely influenced by the presence of inadequate food environments, characterized by limited access to healthy foods and a high availability of highly processed foods (HPF). This study analyzes food consumption in Chilean schoolchildren and the association of this with the Chilean Dietary Guidelines Based on Foods (DGBF) and the HPF consumption. Material and methods The sample (1,094 schoolchildren) was obtained from the baseline of the FONDEF IT18I0016 project, in Santiago-Chile. Anthropometry and socioeconomic data were measured. Dietary intake was assessed using a validated semi-quantitative frequency survey featuring images of food groups aligned with DGBF, as well as HPF. All data were collected by trained professional nutritionists. Associations between dependent and independent variables, and potential confounding factors were calculated using logistic regression models with stepwise backward/forward. A p < 0.05 was accepted as significant, using Stata 16.0. Results Most of the students (54.1%) were with malnutrition by excess and 20.0% exhibited abdominal obesity. Twenty percent of the students met the recommended intake for DGBF (fruits, vegetables, fish, milk and dairy products, legumes, water) and less than 5% did not consume any HPF. Consuming some sub-groups of HPF in moderate quantities (either no consumption or occasional consumption) increases the likelihood of meeting DGBF: candies and sweets (OR: 0.72; p = 0.04), pies with or without filling (OR: 0.63; p = 0.01), and salted snacks (OR: 0.67; p = 0.02).Publication Effects of school closure on lifestyle behaviours and health outcomes in children during the COVID-19 pandemic in Chile: A time-matched analysis(2024) SuĆ”rez, MĆ³nica; FernĆ”ndez-Verdejo, Rodrigo; Quintiliano Scarpelli Dourado, Daiana; Pinheiro Fernandes, Anna Christina; Pizarro Quevedo, TitoBackground :The COVID-19 pandemic led to school closures, potentially impairing children's behaviours and health.

Objetivo: Determinar el tipo del ambiente alimentario que rodea establecimientos educacionales municipalizados de la ciudad de ChillĆ”n. Materiales y mĆ©todo: Se realizĆ³ un estudio descriptivo de corte transversal con una muestra de cuatro establecimientos educacionales municipali-zados y 139 puntos de venta de alimentos. Se utilizaron pautas de observaciĆ³n para medir ambientes alimentarios a 400 metros a partir del punto central de cada escuela. Las pautas evaluaron los puntos de venta de alimentos, segĆŗn disponibilidad, variedad y publicidad de alimentos. Resultados:El 50% de los puntos de venta de alimentos que rodean a los establecimientos educacionales son categorizados como no saludables. Solo un 9% es considerado un punto de venta saludable. Conclusiones: Se observĆ³ una alta densidad de puntos de venta de alimentos no saludables alrededor de las escuelas estudiadas, propiciando un ambiente obesogĆ©nico. Es imperativo establecer polĆticas pĆŗblicas para mejorar el ambiente alimentario escolar. Food environments outside educational establishments influence childrenās diet and nutritional status. Objective: To determine the type of food environment that surrounds the municipal educational establishments of the city of ChillĆ”n. Material and method: A cross-sectional descriptive study was conducted involving a sample of four municipal educational establishments and 139 food establishments. Observation guidelines were used to measure food environments 400 meters from the center point of each school, evaluating food outlets based on food avai-lability, variety, and advertising. Results: 50% of food outlets surrounding educational establishments were categorized as unhealthy. Only 9% were considered a healthy selling point. Conclusions: A high density of unhealthy food outlets was observed around the schools studied, fostering an obesogenic environment. It is imperative to establish public policies to improve the school food environment.Publication Diet quality of Chilean schoolchildren: How is it linked to adherence to dietary guidelines?(2025) Pinheiro Fernandes, Anna Christina; Araneda, Jacqueline; Quintiliano Scarpelli Dourado, Daiana; Pizarro, Tito; Marques, MariaIntroduction: In Chile, the prevalence of overweight among schoolchildren over the age of 5 is approximately 50%, one of the highest in the Americas region.

Conclusion: Our results contribute to reaffirm the need to enhance healthy food consumption among schoolchildren and to discourage the intake of HPF, particularly focusing on specific sub-groups of HPF that may increase the risk of displacing the consumption of food groups recommended by the DGBF.
