Is it possible to obtain food consumption information through children's drawings? Comparison with the Free Listing

The aims of this research were 1) to study the children's drawings to obtain scientific information about food consumption; 2) to compare this method with an existing one (Free Listing); and 3) to compare fruits- and vegetables-consumed by children of different cultural groups within a same country. Children (n = 105) from two Argentinian cities (Salta in the northwest and 9 de Julio in the Pampean region), reported the fruits and vegetables they consumed, with the Free Listing and the new Free Drawing methods. Contingency tables were built and cognitive saliency indexes (CSI) were calculated. Children evoked 57 fruits and 54 vegetables by both methods, which were then grouped into 31 fruit and 27 vegetable categories. The advantages and limitations of the methods are discussed. Throughout Free Drawing, each food was defined by its name, shape and colour, which allowed better discrimination between varieties. Children from Salta reported consuming more fruits (63.7%) and vegetables (68.6%) than those from 9 de Julio (p < 0.05). Differences between cultural groups were found in 10 fruits and 7 vegetables, mentioned more frequently in Salta, where regional crops arose principally by Free Listing. The CSI did not depend on the method used but, for vegetables, they were affected by the cultural group. The fruits with the greatest CSI were banana and apples followed by orange (CSI≥0.19). Tomatoes, carrot and pumpkins showed the highest CSI in 9 de Julio; while carrot, tomatoes, varieties of lettuce and potatoes had the highest CSI in Salta (0.17 ≤ CSI≤0.33). Free Drawing is a qualitative alternative to study food consumption in children populations through a fun activity without the need for assistants.
