    Alimentación laboral: ¿un derecho o un privilegio?
    (Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2025-06-27) López-Arana, Sandra
    La malnutrición por exceso se produce debido a una mayor ingesta calórica, caracterizada por un alto consumo de alimentos ricos en azúcares, sodio y grasas saturadas, así como un aumento en el consumo de alimentos procesados y ultra procesados. A esto se suma un menor gasto energético y un estilo de vida sedentario. En el entorno alimentario organizacional, definido como el lugar donde se venden o proporcionan alimentos a los trabajadores, estudiantes u otros miembros que se desempeñan en instituciones y organizaciones, estas conductas resultan preocupantes porque pueden impactar en la salud de los trabajadores, reduciendo su bienestar físico y mental y disminuyendo su rendimiento. Factores como el estrés, la falta de tiempo para una alimentación adecuada y la escasa disponibilidad de opciones saludables en el lugar de trabajo tienen efecto tanto en la productividad como en la calidad de vida de los trabajadores.

    Prevalence and determinants of energy drink consumption among chilean adolescents
    (MDPI, 2025-11-05) López-Arana, Sandra
    Background: Energy drink (ED) consumption has increased significantly among adolescents worldwide, constituting a high-risk behavior with important public health implications. These beverages are associated with cardiovascular disturbances, sleep disorders, anxiety symptoms, and risky behaviors, especially when combined with alcohol. In Chile, monthly per capita ED consumption among individuals aged 14 to 30 increased ninefold between 2010 and 2020. Objectives: To examine the prevalence of ED consumption and its associated determinants among Chilean adolescents enrolled in grade eight through grade twelve. Methods: Data were drawn from the national representative survey 2023 entitled Fifteenth National Study on the School Population of Chile (ENPE). The final sample included 45,042 adolescents. Besides descriptive analyses, both bivariate and multivariate logistic regression models were used to examine associations between sociodemographic characteristics, parental presence, monitoring, and ED consumption outcomes. Results: Lifetime prevalence of ED consumption was 71.0%, with higher rates in females (72.8%) than males (69.4%). Past-month consumption was reported by 46.2%, with a higher prevalence in males (48.3%) than females (43.9%). Lifetime consumption of ED mixed with alcohol (AmED) was 23.2%, being more frequent among females (26.4%) than males (19.9%). Age, grade level, and indigenous identity were consistently associated with higher odds of consumption. Parental monitoring and involvement indicators were inversely associated with both ED and AmED consumption. Conclusions: This study reveals a high prevalence of ED consumption among Chilean adolescents, with notable gender differences. Family protective factors, particularly parental monitoring and cohesion, emerge as key determinants of this risky behavior and warrant prioritization in public health prevention efforts.

    Uso de pantallas en población infantil: ¿amigo o enemigo?
    (Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2024-12-31) López-Arana, Sandra
    Uno de los hallazgos del Tercer Observatorio Nutricional Nestlé por Niños Saludables- Universidad Finis Terrae e IPSOS, reveló que los niños y niñas de 2 a 5 años no cumplen con la recomendación de la Organización Mundial de la Salud (OMS) de utilizar no más de una hora al día pantallas, ni dispositivos electrónicos. Esta situación empeora a medida que aumenta la edad, siendo los adolescentes quienes llegan a utilizar hasta 8,3 horas diarias de pantallas. El excesivo tiempo en pantallas de nuestros niños, niñas y adolescentes (NNA), deriva de la amplia disponibilidad de estos dispositivos electrónicos, ya que en promedio usan hasta casi tres aparatos tecnológicos (celular, tablet o laptop, los que se reportaron con mayor frecuencia). La problemática del uso y abuso de pantallas por parte de NNA no solo se da en momentos libres u ocio, sino que incluso mientras comen, según relatan las madres, padres o cuidadoras/es. Esta situación va en contravía a lo recomendado en el mensaje número nueve de las recientes Guías Alimentarias (GABAS) para la población chilena que apunta: “En la mesa disfruta de tu alimentación, come acompañado cuando puedas y saca las pantallas.
