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 populatio...Continue Reading
