INTRODUCCIÓN Las enfermedades cardiovasculares constituyen un problema de salud pública por su alta prevalencia y por ser la principal causa de muerte de la población adulta en la mayoría de los países (1). Según diversos estudios, la población de adultos jóvenes parece encaminarse hacia la adopción de conductas de riesgo y estilos de vida poco saludables. Algunos autores lo atribuyen a las débiles conexiones entre la población universitaria con la redes de apoyo; como la familia y los centros educacionales (2,3). Los estudiantes son sometidos a condiciones particulares al ingresar al sistema universitario. El ambiente académico puede producir cambios en sus estilos de vida, con implicaciones positivas y negativas. Se encuentran en una etapa crítica para el desarrollo de sus hábitos alimentarios, caracterizados por presentar poco tiempo para comer, saltarse comidas frecuentemente, comer entre horas, alto consumo de comida rápida, entre otros (4,5). Sumado a esto, presentan una disminución de la práctica de actividad física por el auge que han tenido
Background: On June 27th 2016 the law that regulates sale and advertising of foods high in critical nutrients was implemented in Chile. This law regulates the processed food packaging labelling of foods high in calories, saturated fats, sugars and sodium. Objective: To determine 8-12 year old school children attitudes, from different socioeconomic levels (SEL) and nutritional status, toward the new food labelling law. Methods: A previously validated survey was applied, adding questions regarding the new logos to be added on the packaging of foods and beverages. A descriptive analysis of the variables being studied was conducted and differences in relation to the SEL and nutritional status were determined using the Chi2 test. Results: Statistically significant differences were not observed for gender or city. Regarding the new logos, 87.3% of the children from a medium to high SEL and 78.5% from low SEL indicated that they liked to be informed about the contents of food (p< 0.01). Fifty-three per cent from medium to high SEL and 48% from low SEL would stop buying the foods with logos. Fourteen per cent to 22% will continue to consume sweet biscuits, sugary drinks, chocolates and chips, without a difference in SEL. Children with a normal nutritional status and medium to high SEL placed more importance on logos high in calories, saturated fats and sodium, and children of low SEL on logos high in sugar. Overweight or obese children from medium to high SEL considered all four logos more important than children of low SEL. Discussion: These results will facilitate educational and social marketing support to improve the understanding, compliance and fulfillment of the law.
