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. 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). 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.Publication Geospatial Distribution of Food Environments and Their Association with Sociodemographic Factors in Two Mid-Sized Chilean Cities(2026) Pinheiro Fernandes, Anna Christina; Ayala, Salvador; Quintiliano Scarpelli Dourado, Daiana; Marques, María; Araneda, JacquelineBackground/objectives: The spatial interaction between obesity, diet-related chronic diseases, premature mortality, food environments, and social determinants of health is a global concern. This study aimed to analyze the spatial distribution of healthy and unhealthy food outlets in two medium-sized cities in southern Chile. Methods: A cross-sectional observational study was conducted to characterize the food environment in two medium-sized cities in Chile. Food outlets were geolocated and classified as healthy, regular, or unhealthy, and into four food environment categories (institutional outlets, informal markets, formal markets, and restauration) using validated instruments. Results: Of 1972 identified sites, 1949 were geolocated. Among these, 246 (12.6%) were classified as healthy, 461 (23.7%) as unhealthy, and 1242 (63.7%) as regular. Food environments comprised 1441 stores (73.9%), 366 restauration (18.8%), 136 street food outlets (7.0%), and six institutional food outlets (0.3%). The two lowest socioeconomic quintiles (Q1-Q2) exhibited a lower proportion of healthy food outlets (39.4%). Significant positive spatial autocorrelation was observed for stores, restaurants, and street food outlets (p < 0.005). Conclusions: Food environments were unequally distributed, with a higher density of healthy food outlets in areas characterized by greater population density and higher socioeconomic status. The observed spatial autocorrelation highlights the need for targeted public health interventions to reduce inequalities in access to healthy foods. These findings provide evidence to support policies aimed at promoting more equitable and healthier food environments in medium-sized cities.
