Background: Breakfast is an important meal of the day. The objective of this work is to describe the composition and nutrient supply of breakfast in individuals of the
Autonomous City of Buenos Aires.

Methods: We analyzed data from the First Food and Nutritional Survey of the City of Buenos Aires (EAN-CABA), a cross-sectional study conducted in 2011, in a probabilistic clustered sample of 5,401 individuals of different age groups: children from 0 to 6 months and their mothers, children from 7 to 23 months, preschoolers from 2 to 4 years, school children from 5 to 12 years, adolescents from 13 to 18 years, women of childbearing age (19 to 49 years) and seniors from 60 years. Information on food and beverage consumption was collected through the 24-hour recall method. In order to assess the composition of breakfast, the proportions of consumers of some food from the group of dairy products, fruits and cereals were considered.

Results: A complete breakfast was considered when it included foods from the group of dairy products, fruits cereals. Breakfast is an extended practice among the inhabitants of the Autonomous City of Buenos Aires, more frequent in children and the lower frequency of consumption in adolescents. It contributes between 15.4% and 17.5% of daily calories in all age groups surveyed. With this the eating occasion between a quarter to a third of the calcium and the added sugar intake per day are consumed. It does not represent a moment of commensality for most households, especially in households with adolescents. The percentage of individuals that have a complete breakfast is very low.

Conclusions: In view of the observed results it is necessary to continue working with the population, especially at early ages and adolescents, about the importance not only of making breakfast, but of including foods that ensure the best nutritional quality because of its repercussion in the global quality of the diet as in other aspects of health.

Introducción: El desayuno es una importante ración del día. El objetivo de este trabajo es describir la composición y aporte de nutrientes del desayuno en los individuos de la Ciudad Autónoma de Buenos Aires.

Métodos: Se han analizado datos procedentes de la Primera Encuesta Alimentaria y Nutricional de la Ciudad de Buenos Aires (EAN-CABA), estudio transversal realizado en 2011, en una muestra probabilística por conglomerados de 5.401 individuos de diferentes grupos etarios: niños/as de 0 a 6 meses y sus madres, niños/as de 7 a 23 meses, preescolares de 2 a 4 años, escolares de 5 a 12 años, adolescentes de 13 a 18 años, mujeres en edad fértil (19 a 49 años) y adultos mayores de 60 años. La información de consumo de alimentos y bebidas se recabó a través del método de recordatorio de 24 horas. Para evaluar la composición del desayuno se consideraron las proporciones de que había consumido algún alimento del grupo de lácteos; frutas y cereales. Se consideró desayuno completo cuando incluía alimentos del grupo de lácteos, frutas y cereales.

Resultados: El desayuno constituye una práctica extendida entre los habitantes de la Ciudad Autónoma de Buenos Aires, más frecuente en niños y la menor frecuencia de consumo en adolescentes. Representa un aporte energético de entre el 15,4% y 17,5
