Evaluation of the effectiveness of a nutrition education intervention performed by primary school teachers[article in italian]

This study values the effectiveness of nutrition education interventions carried out by teachers with active didactic methodologies. The research was carried out by administering a frequency of food intake questionnaire, before and after the intervention. To compare the answers given before and after the educational intervention the Wilcoxon-test was applied to dependent data. Our research confirmed that a substantial percentage of children do not show a correct nutrition and therefore nutrition education interventions are opportune and necessary. In the group with « insufficient execution » particular variations are not taken place. In the group with « sufficient execution » increase the number of subjects having breakfast, particularly with milk and biscuits, and decrease the snakes intake. Moreover there is a general decrease of intake food as meat, fish, vegetables, salami and legumes. So this educational intervention seems to have only partial effectiveness.
