- Adolescents snacks: fruit and vegetable consumptionPublication . Alves, Ana Francisca Lemos; Teixeira, Joana Isabel; Barbosa, Rubina; Fernandes, António; Ribeiro, José Carlos; Ferro-Lebres, VeraThe snack meal is defined as the consumption of food ingested in addition to the three main meals, and thereby contributing to additional calories. Increasing the number of snacks may be beneficial, as long as the energy balance is maintained, and are frequently mentioned as an opportunity to increase fruit consumption, however, carbohydrates and added sugars tend to be over-consumed at snacking occasions.The aim of this study was to evaluate the relationship between the prevalence of snack consumption and fruits and vegetables intake in adolescents. A sample of 70 adolescents between 12 and 19 years was studied. The adolescents were assessed for snacks consumption through the three day food diary method and their anthropometric data were objectively measured. Data analysis was performed with the ordinal Spearman correlation test, with a 95% significance, using the SPSS 22.0. Adolescents had a mean of 4.4 meals and 1.5 snacks a day. There was a positive correlation between fruit and vegetables consumption and the prevalence of snacks, the same was observed for the total number of meals and the consumption of vegetables. These results were in agreement to what has been shown by Marques Vidal et al (2006), also regarding Portuguese adolescents. These results suggest that the higher the prevalence of snack consumption, the greater the consumption of fruits and vegetables, signifying a positive relation between snacking and a healthy diet.

- Relação entre refeições intermédias e consumo alimentar em adolescentes portuguesesPublication . Alves, Ana Francisca Lemos; Teixeira, Joana Isabel; Barbosa, Rubina; Fernandes, António; Ferro-Lebres, VeraEste 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.
