Este estudo tem por objetivo estudar a relação entre o número de refeições intermédias e o consumo
alimentar em adolescentes portugueses. Para o efeito, foi conduzido um estudo quantitativo,
observacional, transversal e analítico numa Escola do 3.º ciclo e secundário da Região Norte de
Portugal (NUTS II), baseado numa amostra de 70 adolescentes com idades compreendidas entre os 12
e 19 anos. O consumo de refeições intermédias foi avaliado através do método do diário alimentar de
três dias e os dados antropométricos dos adolescentes foram objetivamente medidos. A análise dos
dados foi realizada por meio do programa SPSS 22.0 (Statistical Package for Social Sciences). Para estudar a
correlação entre as variáveis utilizou-se o teste de correlação ordinal de Spearman ao nível de
significância de 5%. Verificou-se que os adolescentes faziam, em média, 4,4 refeições totais por dia,
sendo que destas 1,5 eram relativas às refeições intermédias. A aplicação do teste da Correlação de
Spearman revelou a existência de correlação positiva entre o consumo de hortícolas, fruta e lacticínios e
o número de refeições intermédias. Estes resultados vêm contrariar resultados de estudos anteriores
também referentes a adolescentes portugueses. Os resultados sugerem que, quanto maior o número de
refeições intermédias, maior o consumo de frutas, legumes e lacticínios, significando uma relação
positiva entre refeições intermédias e uma dieta saudável.
The aim of this study was to evaluate the relationship between the frequency of snacks and food intake in Portuguese adolescents. Therefore, a quantitative, observational, cross-sectional and analytical study was carried out in a third cycle and secondary School in the Northern Region of Portugal (NUTS II) based on a sample of 70 adolescents aged between 12 and 19 years. Intermediate meals were assessed using the food diary method of three days and adolescents’ anthropometric data was measured objectively. Data analysis was performed using the SPSS 22.0 software, and the ordinal Spearman correlation test, using a 5% significance level. On average, adolescents had 4.4 meals a day, of which 1.5 were intermediate meals. There was a positive correlation between the consumption of vegetables, fruit and dairy products and the number of intermediate meals. These results contradict previous studies regarding Portuguese adolescents. These results also suggest that the higher the number of intermediate meals, the greater the consumption of fruit, vegetables and dairy products, signifying a positive correlation between intermediate meals and a healthy diet.
