Stages of change in the purchase of ultra-processed snacks among university students after the implementation of the chilean food law; a multi-center study

The Objective is to determine the stages of change in the behavior of university students regarding the purchase of ultra-processed snacks consumed. Multi-center study (14 Chilean universities). The participants (4,807 students)evaluated were applied a survey to determine the stage of change of behavior regarding the purchase of foods with warning signs. The students were evaluated and classified as (a) Nutrition Students, (b) Healthcare-related Students and (c) Other degree Students. More than 90% of the students were aware of the food regulation and knew the warning signs. More than 60% of Healthcare-related and Other degree students are in the stage of pre-contemplation or contemplation regarding purchase intent of sugary drinks, juices, cookies, sweet snacks and potato chips; this value is twice the percentage of Nutrition students in this stages ( Chi2, p<0.001). In conclusion there is a high proportion of pre-contemplation and contemplation with respect to purchase intent among the students(AU)

Determinar las etapas de cambio en el comportamiento de los estudiantes universitarios con respecto a la compra de colaciones ultraprocesadas. Estudio Multicéntrico (14 universidades chilenas). A los participantes (4.807 estudiantes) se les aplicó una encuesta para determinar el cambio en el comportamiento con respecto a la compra de alimentos con sellos de advertencia. Los estudiantes se clasificaron como (a) estudiantes de nutrición, (b) estudiantes del área de la salud y (c) estudiantes de otras carreras. Se evaluaron. Más del 90% de los estudiantes conocían la regulación alimentaria y conocían las señales de advertencia. Más del 60% de los estudiantes de la salud y de otras carreras se encuentran en la etapa de pre-contemplación o contemplación con respecto a la intención de compra de bebidas azucaradas, jugos, galletas, bocadillos dulces y papas fritas; Este valor es el doble del porcentaje de estudiantes de nutrición en estas etapas ( Chi2, p <0,001). Se concluye que existe una alta proporción de pre-contemplación y contemplación con respecto a la intención de compra entre los estudiantes universitarios(AU)

Asociación entre sedentarismo y malos hábitos alimentarios en estudiantes de nutrición / Association between sedentarism and bad dietary habits among nutrition students

El sedentarismo se relaciona con disminución a la sensibilidad de insulina y acumulación de tejido adiposo visceral. Lo que sumado a malos hábitos alimentarios, explican en parte el aumento global de sobrepeso y obesidad. En Chile el exceso de peso afecta a 64,4% y el sedentarismo al 88,6% de la población.El objetivo es determinar los niveles de sedentarismo en los estudiantes de la carrera de Nutrición y Dietética y evaluar si existe asociación con sus hábitos alimentarios. Se evaluaron 607 estudiantes de la carrera de Nutrición y Dietética aplicándoles una evaluación antropométrica de peso y talla, una encuesta de evaluación alimentaria y una encuesta de actividad física. Resultados: El porcentaje de mujeres sedentarias fue significativamente mayor que en los hombres (74,3% v/s 40,5%). Además,las mujeres que nunca cenabancasi duplicaron el porcentaje observado en los hombres. Finalmente,al comparar 2 grupos de estudiantes, unocompuesto por los que nunca desayunaban, ni cenaban y otro por los que desayunaban y cenaban todos los días,se determinó que existe asociación entre actividad física y la conducta alimentaria (♩2= 10,56; p=0.001) En este estudio se determinó que los individuos jóvenes sedentarios presentaban un mal comportamiento alimentario que quienes realizaban algún tipo de actividad física. Nuestros resultados sugieren que realizar algún tipo de actividad física se asocia a un mejor patrón de alimentación(AU)

A sedentary lifestyle is associated with decreased insulin sensitivity and accumulation of visceral adipose tissue. Which combined with poor eating habits, explain the overall increase in overweight and obesity. In Chile overweight it affects 64.4% and 88.6% sedentary population. The objective was to determine the levels of sedentarism in Nutrition and Dietetics students's and evaluate whether there is an association with eating habits. 607 students from Nutrition and Dietetics were evaluated by applying an anthropometric weight and height assessment, a food assessment survey and a physical activity survey. Results: The percentage of sedentary women was significantly higher than in men (74.3% v / s 40.5%), also women who never eat dinner nearly twice the percentage observed in men. Finally, students who performed some type of physical activity had a significantly higher percentage in the frequency of consumption of breakfast and dinner, with respect to sedentary students. Determining an association between physical activity and eating behaviour (♩2= 10,56; p=0.001). This study determined that young sedentary individuals had a worse eating habits than those who performed some type of physical activity. Our results suggest that perform some type of physical activity is associated with better eating pattern(AU)

Evolución clínica de pacientes chilenos con tirosinemia tipo I tratados con 2-(2-nitro-4-trifluorometilbenzoil)-1,3-ciclohexanediona (NTBC) / Clinical follow up of Chilean patients with tyrosinemia type 1 treated with 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-ciclohexanedione (NTBC)

Background: Tyrosinemia type I is an inborn error of metabolism due to deficiency of fumarilacetoacetase. Acute presentation is with liver failure, hypophosphatemic rickets and peripheral neuropathy. Chronic presentation is with visceromegaly and subclinical rickets. The most severe complications are hepatic cancer and acute neurological crises. Without treatment, tyrosinemia type 1 is fatal. In 1992 treatment for tyrosinemia type 1 with 2-(2-nitro-4-trifluoromethybenzoyl)-1,3-ciclohexanedione (NTBC) was proposed. A clinical response was reported in 90% of patients. In cases that did not respond, a successful liver transplantation was performed, reducing mortality to 5%. Aim: To report the follow up of 12 patients treated with NTBC. Patients and Methods: Review of clinical records of 12 Chilean cases treated with NTBC at the Instituto de Nutrición y Tecnología de los Alimentos (INTA) from January 2004 until June 2010. Results: In all patients, a rapid metabolic control was achieved. Two patients developed hepatocarcinoma. One of these patients died and one was successfully treated with liver transplantation. One patient died after receiving a liver transplantation. Nine patients have at present good liver function, but 2 had peripheral neuropathy due to late diagnosis and discontinuing NTBC treatment. Conclusions: Treatment with NTBC allows metabolic normalization in tyrosinemia type 1, prevents liver cirrhosis and hepatic cancer, improving survival rates and quality of life in the patients. Neonatal screening is essential for the early diagnosis of this treatable disease, that otherwise may be lethal.
