Special Considerations

The publication which describes the development of the FFQ by Lanham & Bolton-Smith,1993 could not be accessed. The structure of the questionnaire was based on the Caerphilly FFQ (Yarnell et al., 1983) used in the Scottish Heart (Bolton-Smith & Milne, 1991).Changes were made to the order of questions and foods commonly consumed in north-east Scotland were added. An update to the food composition table is required.
