    <jats:p>This study investigated Chilean employees expectations, perceptions of acceptability, and beliefs about the potential effectiveness of non-monetary incentives in workplace weight loss programs. Eighty-six employees with overweight and sedentary occupations from six Chilean companies participated in 16 focus groups as part of a descriptive qualitative study. The content analysis, grounded in Self-Determination Theory, revealed eight categories grouped into three overarching themes: 1) Beliefs and challenges regarding healthy habits and body weight. 2) Workplace structure, environment, and culture. 3) The use of non-monetary incentives to promote healthy behaviors at work. While participants appreciated the non-monetary incentives, these were not enough to overcome the psychological, emotional, and structural barriers to adopting healthier lifestyles. Non-monetary incentives that provided additional spare time, particularly for family, were the most appreciated by participants; nevertheless, organizational constraints restrict the use of these incentives in workplace weight loss initiatives. In conclusion, although non-monetary incentives were identified as a strategy to promote healthier lifestyles, their success is dependent on implementing structural and cultural modifications in the work environment. A comprehensive strategy that considers both individual and organizational factors is needed to promote sustainable healthy habits.</jats:p>

    <jats:p>Introducción: La compra y venta de alimentos en línea ha experimentado un aumento significativo en todo el mundo, propiciado por un mayor acceso a las tecnologías y dispositivos electrónicos. Objetivo: evaluar la asociación entre la exposición a servicios de compra y venta de alimentos en línea y el estado nutricional de los universitarios. Material y métodos: Participaron 587 estudiantes de Universidad del Bío- Bío, Chile. Se aplicó un cuestionario online que incluía preguntas sobre el uso de aplicaciones de delivery y las influencias del entorno en la compra de alimentos. Se realizó un estudio de clúster y se desarrollaron modelos de regresión logística. Resultados: Se obtuvieron 3 clústers de exposición a plataformas de entrega de comida a domicilio, mediante un análisis de conglomerados (MCA K-means): expuestos a estímulos tradicionales (n=198), poco expuestos (n=196) y altamente expuestos (n=193). Quienes están altamente expuestos a plataformas digitales de comida a domicilio, tienen mayor probabilidad de tener malnutrición por exceso (OR=1,53; p = 0,048). Comprar comida vegetariana, vegana o sin gluten es un factor protector de la malnutrición por exceso (OR= 0,65; p = 0,049). Conclusión: Existe relación significativa entre la utilización de servicios de compra y venta de alimentos en línea y el estado nutricional de estudiantes universitarios. Los resultados sugieren que el acceso y uso de estas plataformas podría influir en los patrones alimentarios y, en consecuencia, en el estado nutricional de esta población.</jats:p>

    <jats:p>The analysis of the food environment is used to identify areas with gaps in the availability of healthy foods and can be used as a public policy assessment tool. In recent decades, Chile has implemented several strategies and regulations to improve food environments, with encouraging results. Little is known about the scope of these measures in socially vulnerable environments. This study is part of a project that seeks to build an integrated intervention model for healthy school environments in a vulnerable area of Santiago, Chile. The objective of this study was to evaluate the availability of healthy and unhealthy foods around schools and the relationship between it and socioeconomic determinants of the school community in the Chilean context. A cross-sectional study to measure the food environment of informal markets (street food), formal markets (stores), and institutions (schools) was conducted in and around 12 schools (100 m surrounding schools) in a vulnerable urban area of Santiago, Chile. A lack of healthy foods was observed, which was related to some socio-economic determinants and the multidimensional poverty was the most relevant. The diagnosis of food environments around schools can represent an important target for governments to implement policies focused at improving the availability of healthy foods.</jats:p>

    Diet quality of Chilean schoolchildren: How is it linked to adherence to dietary guidelines?

    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.</jats:p> </jats:sec> <jats:sec id="sec002"> <jats:title>Material and methods</jats:title> <jats:p>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 &lt; 0.05 was accepted as significant, using Stata 16.0. <jats:p>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).</jats:p> 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.</jats:p>
