This document was added 11/06/2015.
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 Department of Health (e.g. in relation to guidelines on time undertaking physical activity per week).
The data items and related output categories currently available for the National Nutrition and Physical Activity Survey TableBuilder database, Basic CURF and Expanded CURF are available in Excel spreadsheet format from the Downloads page of this product.

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. For information on the structure of individual microdata products, see the Using the TableBuilder, Using the Basic CURF and Using the Expanded CURF pages within this product.
