The following paragraphs may be used to describe the AES FFQs in publications and reports
The AES FFQ is a 120-item FFQ with 15 supplementary questions. The FFQ is designed to collect information about dietary intake over the participants previous 6 months. It is a semi-quantitative FFQ with a standard portion size provided for each food item and determined using ‘natural’ serving size (eg. slice of bread) where possible. In the absence of a natural serving size, portion sizes were derived from the Australian Bureau of Statistics (ABS) unpublished data from the 1995 National Nutrition Survey (NNS) for children, adolescents and adults, with the data for toddlers derived from the 2007 National Children’s Nutrition and Physical Activity Survey, purchased from the Australian Social Science Data Archive at the Australian National University. An individual response for each food, or food type, is required, with frequency options ranging from ‘Never’ to ‘4 or more times per day’, but varied depending on the food, with some drinks items up to ‘7 or more glasses per day’. Nineteen questions relate directly to intake of different vegetables and 1 to consumption at the evening meal and 11 relate to fruit, with the availability of some seasonal fruits adjusted for in the nutrient calculations. The availability of seasonal fruit was determined by data obtained from fresh food markets in Sydney, New South Wales, in addition to referring to supermarket literature that indicated the number of months each year that seasonal fruit was available.
The AES FFQs has been thoroughly evaluated for reliability and validity in Australian toddlers, children and adults and has demonstrated acceptable accuracy for ranking nutrient intakes. The AES FFQs has been validated against biomarkers and food records (see references below). In addition, a diet quality index for children and adolescents, the Australian Child and Adolescent Recommended Food Score (ACARFS) has been developed (Marshall 2012). Additional validation studies related to the AES FFQs in toddlers, children and adults have been completed (see references below).
Nutrient intakes from the FFQ were computed using the Australian food composition database, [select the relevant database used either AusNut 1999 (All Foods) Revision 17 or AusNut 2011-2013 depending on food composition database chosen upon set up],
primarily and AusFoods (Brands) Revision 5 (Australian Government Publishing Service, Canberra) to generate individual mean daily macro- and micronutrient intakes.
The AES includes additional questions about daily consumption of fruit, vegetables, dairy products, sweetened beverages and snack foods, as well as the type of bread and dairy products used. Six questions address health-related behaviours such as frequency of consumption of breakfast, takeaway food and vitamin supplements, with further questions about sedentary activities, specifically time spent watching television or playing computer games.
