FILE STRUCTURE

Information from the survey was stored electronically in the form of data items. In some cases items were formed directly from individual survey questions, while in others items were derived from answers to several questions (e.g. Body Mass Index derived from measured height and weight). Some items were derived with reference to information from other organisations such as the National Health and Medical Research Council (e.g. in relation to guidelines on fruit and vegetable consumption).

Datasets from the Australian Health Survey are hierarchical in nature. A hierarchical data file is an efficient means of storing and retrieving information which describes one to many, or many to many, relationships (e.g. respondents may have been diagnosed with more than one condition and each condition is given a condition status for whether it's current and long-term, current but not long-term or not current).

The data items and related output categories currently available for the Australian Health Survey, Core Content TableBuilder database and Expanded CURF are available in Excel spreadsheet format from the Downloads page of this product.

The following table shows the levels available in each microdata product and the information contained on those levels:
