Resumo

Este estudo pretendeu avaliar o efeito de duas metodologias de educação alimentar (software interactivo e sessões alimentares) no consumo e no conhecimento das recomendações de fruta e vegetais (F&V) em adolescentes. Foram avaliados 161 estudantes (idade mediana =14 anos), pertencentes a 3 grupos seleccionados aleatoriamente: no primeiro grupo aplicou-se uma sessão com software interactivo, o segundo recebeu cinco sessões de educação alimentar e o terceiro grupo não foi sujeito a qualquer intervenção. Usou-se um questionário auto-aplicado para avaliação da ingestão de F&V e dos conhecimentos sobre as recomendações, em dois momentos separados de dois meses. Foi observado um aumento médio de 0,74 e 0,55 porções na ingestão total de F&V no grupo 1 e 2, respectivamente. Contudo, estes aumentos não foram significativamente diferentes dos encontrados no grupo controlo (0,20) nem suficientes para alterar significativamente a proporção de indivíduos com um consumo superior a 5 porções F&V/dia. A proporção de alunos com conhecimentos sobre a ingestão recomendada de F&V aumentou significativamente nos grupos sujeitos a intervenção, quando comparados com o grupo controlo. As intervenções tiveram maior impacto no aumento dos conhecimentos do que no consumo de F&V.

Abstract

Effect of Two Nutrition Education Methodologies in Adolescents’ Intake and Knowledge About Recommendations of Fruit and Vegetables

This study aimed to evaluate the effect of two nutrition education methodologies (interactive software and nutrition education sessions) in adolescents’ fruit and vegetables (F&V) intake and knowledge about recommendations on the intake of F&V.One hundred and sixty one students (median age=14 years) were evaluated and divided into three groups: the first group received one session with the interactive software, the second received 5 nutrition education sessions and the third was not submitted to any intervention. F&V intake and knowledge about recommendations were evaluated using a self-administered questionnaire, at baseline and two months after intervention. An increase of 0.74 and 0.55 servings on total F&V intake was found in group 1 and 2, respectively. However, these increases were not significantly different from the control group (0.20) and did not significantly change the proportion of students with total F&V intake of 5 or more servings per day. Knowledge about F&V intake recommendations increased significantly in the intervention groups, compared with the control group. The interventions were less successful in increasing F&V intake rather than knowledge about recommendations on the intake of F&V.
