Abstract

Introduction: The Nestlé–Universidad Finis Terrae Nutritional Observatory was created in response to the limited information available on the diet, nutrition, and lifestyles of Chilean children and adolescents. Objective: To describe the characteristics of the Nestlé–Finis Terrae Nutritional Observatory and the main findings from the 2022–2024 period. Subjects and methods: Since 2022, structured telephone surveys have been conducted with adults who identify as parents of children and adolescents aged 2 to 15 years, residing in Chile. These surveys monitor the eating behaviors and lifestyle habits of parents, caregivers, and their children. Results: One of the main findings was a high perception of balanced family nutrition, with relatively stable values across the years: 57% (95% confidence interval, CI 95%: 52.9–61.0) in 2022, 51% (CI 95%: 46.9–55.1) in 2023, and 56% (CI 95%: 51.9–60.0) in 2024. A steady increase in improvised eating was observed, rising from 51% in 2022 to 60% in 2024. Concern about food prices also grew, from 17% in 2023 to 25% in 2024. In 2023, the highest level of perceived undiagnosed allergies and intolerances was recorded (33%, CI 95%: 29.2–36.9). Additionally, there was evidence of underestimation of children’s actual nutritional status and low adherence to recommendations regarding physical activity and screen time. Conclusion: The observatory is distinguished by its standardized methodology and annual data collection, providing consistent information on perceptions related to child health and nutrition. Although the use of self-reported data is a limitation, the findings offer valuable input for the development of public policies and educational strategies aimed at promoting healthier lifestyles among Chilean children and adolescents. © 2025 Los autores.
