O objetivo deste trabalho de investigação é avaliar os hábitos alimentares de alunos de duas escolas
públicas do norte de Portugal e, em particular, as diferenças entre os consumos durante a semana e o
fim de semana. Para isso, desenvolveu-se um estudo observacional, quantitativo, analítico e transversal.
Os dados foram recolhidos com recurso a um diário alimentar de três dias, dois dias da semana e um
do fim de semana aplicado a uma amostra por conveniência de 319 alunos. A comparação dos hábitos
alimentares entre a semana e o fim de semana recorreu a uma análise estatística com aplicação de testes
de localização, nomeadamente, Teste T-Student, Teste de Wilcoxon e Teste do Sinal, utilizando o software
estatístico Statistical Package for the Social Sciences, versão 20. Constatou-se um consumo
significativamente superior de fruta (p-value = 0,002), hortícolas (p-value = 0,000), leguminosas (p-value =
0,000), lacticínios (p-value = 0,000) e gorduras monoinsaturadas (p-value = 0,020) durante a semana,
enquanto no fim de semana se observou um consumo significativamente superior de bebidas
açucaradas (p-value = 0,000). Verificou-se que o consumo de energia, fibra dietética, cálcio e ferro,
assim como de todas as porções de alimentos era significativamente inferior relativamente às
recomendações, e o consumo de carne, peixe e ovos era significativamente superior às recomendações,
tanto durante a semana como durante o fim de semana. O padrão de alimentação dos alunos era mais
saudável durante a semana do que no fim de semana.
The objective of this research was to evaluate the eating habits of students from two public schools in the north of Portugal and, in particular, the differences between weekdays and weekend consumption. For this, an observational, quantitative, analytical and cross-sectional study was developed. The data were collected using a food diary of three days, covering two days of the week and one of the weekend that was applied to a convenience sample of 319 students. Comparison of dietary habits between weekdays and weekend was based on a statistical analysis with the application of localization tests, namely, Student's T-Test, Wilcoxon Test and Signal Test, using the statistical software Statistical Package for the Social Sciences. The results showed a significantly higher consumption of fruit (p-value = 0.002), vegetables (p-value = 0,000), pulses (p-value = 0,000), dairy products (p-value = 0,000) and monounsaturated fats value = 0.020) during the week, while at the weekend a significantly higher consumption of sugary drinks (p-value = 0.000) was observed. It was verified that the consumption of energy, dietary fiber, calcium and iron, as well as all type of food portions was significantly lower than the recommendations, and the consumption of meat, fish and eggs was significantly higher than the recommendations both during the week and during the weekend. The students' eating pattern was healthier during the week than at the weekend.
