Abstract

The present study was designed to estimate the average food and nutrient intake in a sample of Italian students living in the District of Rome. In the school year 1999-2000 all students belonging to the first, second or third year of nine randomly selected secondary public schools were contacted for filling in a food frequency questionnaire (3982 subjects). The next year, 233 of them (125 males and 108 females), randomly extracted, participated in a detailed food survey. Food intake was assessed on the basis of 12 (four consecutive days in three different periods) 24-h dietary records. The average daily intakes of fruit (107±100 g/day), vegetables (186±74 g/day) and legumes (16±29 g/day) were lower than recommended. The percentage of energy intake from fat (39%) and that from saturated fats (12%) were high. On the other hand, the percentage of energy intake from carbohydrates was low (45%) even if that from sugar (14%) was rather high. The students' diet was characterized by low intakes of fibre (16±6 g/day) and calcium (710±247 mg/day) in both males and females. Iron intakes were lower than 12 mg/day in a very high percentage of females (80%), suggesting that iron deficiency may be present in this population group. Results indicate that the diet of these students is both unbalanced in terms of macronutrients and deficient for some micronutrients, suggesting the need for intervention.
