Relação entre conhecimentos alimentares e os níveis de atividade física em jovens adolescentes portugueses

Abstract

Background: The purpose of this dissertation is to verify if there is a relation/connection between the practiced physical activity and the nutritional knowledge of the adolescents. Methods: In this study, an accelerometer was used by each of the 202 students and nutritional knowledge questionnaire known as QCNA was applied. Results: The results obtained through the recovered data, show that the initial hypothesis was countered, which means, that there is no significant association between the physical activity practiced by the students and their nutritional knowledge. However, there are a number of secondary results encountered throughout the analysis of the data, including, for instance, the larger nutritional knowledge and lower levels of physical activity of students with a higher degree. Conclusion: No significant associations were observed between physical activity and nutritional knowledge. After analyzing the data, it can be concluded that a longitudinal study is required, in order to understand if these results have any impact in a larger period of time or if this was just the case for the period of time we evaluated. This study can serve as a guide to other investigators, so they will know where to look for possible answers.
