ABOUT THE SURVEY
The 1995 National Nutrition Survey (NNS) is a comprehensive survey of Australians' diets. Detailed information was collected from people aged two years and over on food and beverage intake, physical measures, food-related habits and attitudes, and usual frequency of consumption of selected foods. Nutrient intake was later derived from reported food and beverage intake. The survey was a joint project between the Australian Bureau of Statistics (ABS) and the Commonwealth Department of Health and Family Services.
SCOPE AND COVERAGE
The survey was conducted from February 1995 to March 1996 in all States and Territories across urban and rural areas. A sample of participants from the 1995 National Health Survey (NHS) were invited to participate in the NNS, with the NNS interview taking place several weeks after the NHS interview.
The survey was conducted under the authority of the Census and Statistics Act 1905, on a voluntary basis.
The NHS sampled approximately 23,800 private dwellings (houses, flats, etc.) and non-private dwellings (including hotels, boarding houses and institutions). Households were selected at random using a stratified multistage area sample which ensured that persons within each State and Territory had a known and, in the main, equal chance of selection in the NHS.
Certain groups of persons were excluded from the scope of the NHS. These were non-Australian diplomatic personnel and non-Australian members of their households, persons from overseas holidaying in Australia, members of non-Australian defence forces and their dependants stationed in Australia, and persons in special dwellings (including hotels, boarding houses and institutions).
The NNS sample was systematically selected from the base NHS sample of private dwellings only. Approximately 13,800 persons aged two years and over agreed to participate in the NNS.
The NNS was conducted on a maximum of two in-scope people per household in urban areas and three in-scope people in rural households. To increase the sample in Queensland, three people were invited to participate in both urban and rural households. These people were randomly selected from those living in the household. In addition, all people aged 65 years and over, who lived in households selected for the NHS, were invited to participate in the NNS.
A sub-sample of approximately 1,500 NNS participants provided Day 2 food intake data. This was for a second 24-hour period on a different day of the week and usually within 10 days of the first interview.
