Abstract
The aim of this study was to develop and test the reliability and relative validity of a food frequency questionnaire (FFQ) specifically developed for individuals living in Sicily, southern Italy. This study was conducted on a convenient sample of 178 adult volunteers aged 18-80 years recruited in the urban population of Catania. Dietary intake estimated by 2 FFQs was compared with six 24-h recalls covering a period of 10 months. A total of 110 food items were included in the FFQ. Person's coefficients between the first FFQ and mean of the six 24-h recalls showed high correlations for coffee, tea, pasta and dairy products, alcohol, total fats and carbohydrates (in women). The test-retest analysis showed high reproducibility of the FFQ. We showed that our FFQ provided a useful estimate of both food and nutrient intake in a healthy adult population.Entities:
