| Popis: | The calcium intakes of 35 072 Italian schoolchildren aged 7 – 10 years were investigated as part of a nation-wide survey of nutritional patterns. The Friuli, Piedmont, Latium and Sicily regions of Italy were selected as representative of the nation's north–south and east–west socio-economic divisions. A food-frequency questionnaire was used to assess the nutritional intakes of the whole sample. The validity of the food-frequency questionnaire method was assessed in a sub-sample of children by traditional methods: 24-h dietary recall and a weighted food diary. The data indicate that the mean calcium intakes of girls were below the recommended daily intake of 800 mg in all of the regions except Sicily, and that the calcium intakes of boys were above the recommended daily intake in all of the regions except Friuli. These results suggest that there may be deficiencies in the calcium intakes of this age-group in the wider population, particularly in girls. Food-frequency questionnaires are potentially valuable as part of a multi-method approach in large-scale nutritional monitoring. |
