Nutritional status and dietary behaviours of Northern Algeria university students

Abstract The present study tries to assess the nutritional status and dietary behaviours in a group of undergraduate students in order to characterize their food habits and assess the quality of their diet. A cross-sectional study was conducted with 220 undergraduate university students (110 male and 110 female) aged between 19 and 24 years from the Food Department of Saad Dahlab Blida 1 University (Algeria). The data collection and nutritional evaluation were carried out using DIAL nutritional software. Male participants had significantly (P < 0.005) higher body mass index (BMI) when compared to females. Significantly higher percentages of female students (P < 0.005) had tried a low-fat diet (P = 0.0075) and a low-carbohydrate diet (P < 0.005). The prevalence of overweight was higher among males compared to females. In contrast, a greater percentage of underweight students were observed in the group of female subjects. Related to micronutrient intake, a significant difference by sex was observed for vitamin A, C, folic acid, iron, calcium, and sodium intakes. However, females consumed more food containing vitamins C and A, whereas males’ intake of calcium, sodium, folic acid, and iron was higher than the corresponding values observed in females. To conclude, these students reported a diet characterized by a high variety of cereal products and a moderate amount of vegetables, milk and dairy products, meat, fish and eggs, dietary fats and beverages, whereas the consumption of fruits was highly infrequent.
