“…Estos resultados concuerdan con Cerdeño, quien encontró también que el atún es una de las especies de mayor consumo para el contexto español 20 ; para el caso argentino, el atún se ubica en segundo lugar, después de la merluza 21 . 23 . Lo anterior implica la importancia de implementar estrategias para mejorar la ingesta de pescado en población universitaria, por cuanto otros autores como Castro-González et al 24 .…”

“…Por otra parte, en cuanto a las preferencias por el tipo de preparación de los pescados y mariscos se encontró diferencia significativa entre sexos, lo cual indica que ésta ajustada por preferencias de hombres y mujeres, puede ser una estrategia para incrementar el consumo, por cuanto otros autores han encontrado que las principales razones para no hacerlo, son el sabor y la dificultad en su preparación 23 ; por esta última razón otros autores explican el caso de estudiantes que a pesar de tener preferencia por el pescado, no son quienes lo adquieren mayor frecuencia 22 . Rodríguez por su parte, destaca el precio como una de las limitantes para ello, planteando la necesidad de mejorar los sistemas de producción para desarrollar variedades económicas al alcance toda la población, como la trucha, tilapia y cachama 27 .…”

Salud. 2016; 18(2):257-265. DOI: http://dx.doi.org/10.22267/rus.161802.36 Resumen Introducción: El conocimiento relacionado con el consumo de pescado es de vital importancia para establecer estrategias que permitan mejorar su consumo en esquemas de alimentación saludable. Objetivo: Identificar preferencias y frecuencia de consumo de pescados y mariscos en estudiantes universitarios de la ciudad de Medellín, Colombia. Materiales y métodos: Se utilizó un tamaño de muestra de 400 estudiantes, con base en un nivel de confiabilidad del 95% y un error máximo permisible del 4,9%. Los estudiantes fueron seleccionados aleatoriamente de acuerdo con los factores de ponderación: sexo, nivel socioeconómico y tipo de universidad y fueron entrevistados personalmente. Se realizó análisis factorial de correspondencia múltiple con clasificación jerárquica indexada y análisis multivariado de la varianza MANOVA con contraste canónico de tipo ortogonal. Resultados y conclusión: Se encontró que las especies de mayor preferencia entre los universitarios son atún, bagre, tilapia, trucha, róbalo y camarón; los de menor preferencia son: lenguado, perla, arenque y corvina. Se encontró diferencia estadística (p<0,05) entre sexos en el consumo regular de pescado; los hombres manifiestan un consumo semanal de calamar y sardina, mientras las mujeres consumen semanalmente atún, bocachico, langostino, ostras y pargo.Palabras clave: Consumo de alimentos; hábitos saludables; nutrición, alimentación y dieta en adolescentes.

“…The Bartlett test of sphericity is based on the statistical distribution of chi‐square and tests the null hypothesis (no correlation between the variables). Levels of significance lower than 0.100 indicate that the data are suitable for the treatment with FA, and, therefore, there are correlations between the variables (Maciel et al, ; Yong & Pearce, ). The Cronbach's Alpha Coefficients are related to the level at which the measurement is error‐free and, therefore, presents consistent results.…”

The bottled mineral water sector is strategic to countries like Brazil and understanding the factors that guides the purchase and consumption by men and women becomes vital to the product's commercial success. In this context, projective techniques are important tools to comprehend the consumers' perception and to the development of target strategies of marketing. Therefore, the objective of this study was to investigate the gender differences about the bottled mineral water's perception through using Word Association (WA) alongside with the Partial Least Squares—Discriminant Analysis (PLS‐DA). The results demonstrated that from the 12 listed categories for the product, the most common were: “necessity,” “well‐being,” “quality,” and “appearance,” and it was possible to identify through PLS‐DA the main differences (p < .05) between genders. The bottled mineral water consumption by the female public is possibly directed to necessity and well‐being, despite practicality, while the male public made the purchase and consumption of the product associated to brand and informal places. Yet, it was realized that the product's presentation and quality parameter were highly impactful in the consumers' attitudes from both sexes. It is highlighted that the WA and PLS‐DA tools, used together in an innovative way, contribute to the deep acknowledgment about the bottled mineral water's consumption, and their application can be expanded and adopted routinely in marketing research and in the new marketing strategies. Practical applications This study brings relevant information about the factors which should be considered by consumers at the moment of purchase and consumption of bottled water, emphasizing the differences by gender, with the advantage of the results being obtained using simple sensory methodologies, as the Word association task which taken in account the consumers' perception and evaluated for multivariate approaches, as Partial Least Squares—Discrimination Analysis. These findings should be considered to bottled water industry to elaborate marketing messages to increase their sales in an effective way.

“…Each region grows and consumes different types of vegetables because of ecological and geographical differences, the impact of national consumption culture, and social dimensions associated with the habits the society gained over time. Assessing food consumption is complex due to the various factors involved (Maciel et al, 2013). A healthy and balanced diet is one of the main factors for a peaceful and happy life.…”

Many factors impact on food consumption behaviours. The aim of the study is to determine the impact of socio-demographic and ecological factors on vegetable consumption. A 14-question questionnaire was applied on a voluntary basis to 200 individuals who accepted to participate in the study. Their socio-demographic attributes and the vegetable consumption habits of their families were determined. Their average monthly budget for vegetables is € 31.82±12.72. The two attributes of purchased vegetables with most demand are cleanliness (61.5%) and freshness (22%). The maximum price per 1 kg of vegetables, which individuals with an income of € 301-450 can afford, is € 0.96, but for individuals with an income of > € 450, it is € 1.25. It was observed that the amount of purchased vegetables increased with the increase in the budget allocated for vegetables.
