Preliminary Results of a Nutritional Survey in a Sample of 35 000 Italian Schoolchildren

An investigation of the nutrient intake of a large-scale sample (n = 35 072), drawn from the Italian school-age population (7- 10 years) was carried out in a nationwide survey of nutritional patterns. Friuli, the Piedmont, Latium and Sicily regions were selected as representative of the nation's north-south and east-west socio-economic divisions. A food frequency questionnaire was used to assess nutritional intake. Traditional methods of 24-h dietary recall and a weighted food diary were used in sub-samples to assess thd ' validity of the food frequency questionnaire. Our data suggest that the average diet of Italian schoolchildren is rich in protein (especially animal proteins) and lipids (prevalently saturated fatty acids), but that carbohydrate and fibre intakes remain generally low. The relatively low calcium intake among girls and a widespread, more than adequate iron intake are also noteworthy. The food and nutrient intakes assessed suggest a dietary pattern with several positive points, but also reveal potential hazards for a wider population spectrum. The type of large-scale nutritional monitoring with a multi-method approach can be used in Italy and elsewhere to describe the dietary trends of a school-age population
