Special Considerations

This tool is unavailable. The tool is based on that used in the US Nurses Health Study (Willett et al., 1985, 1998) and was adapted for the EPIC project in the UK after discussions with the tools project team. The tool was also used as a model for the EPIC baseline survey. There are only some very minor differences e.g. colour versus black and white photos for portion size estimation, between this tool and the ones used in the EPIC studies.
