Results in this publication contain information from the full Australian Health Survey Core sample of 32,000 people (a combined data file of both the National Health Survey (NHS) and the National Nutrition and Physical Activity Survey (NNPAS) for persons aged 2 years and over). This compares with a sample of 20,500 people used for Australian Health Survey: First Results, 2011-12 (cat. no. 4364.0.55.001). For more information on the structure of the AHS, see Structure of the Australian Health Survey.
With a larger sample size, the Core provides more accurate estimates and allows for analysis at a finer level of disaggregation. Results in this publication are, for the most part, consistent with those in Australian Health Survey: First Results, 2011-12 (cat. no. 4364.0.55.001), with the key exception of diabetes due to a definitional change. For further information on the comparability between estimates from the two publications see Comparison of First Results and Updated Results).
Results in this publication are from a combined data file of both the NHS and NNPAS (referred to as the Core) and therefore differ from previously published data from the 2011-13 AHS. With a larger sample size (approximately 32,000 people), the Core provides more accurate estimates and allows for analysis at a finer level of disaggregation. However, the Core only contains those data items common to both NHS and NNPAS, and therefore does not provide the full spectrum of data items from the AHS. For more information on the structure of the AHS, see Structure of the Australian Health Survey.
The Updated Results, 2011-12 uses a combined sample from the National Health Survey (NHS) and the National Nutrition and Physical Activity Survey (NNPAS).The 2011-12 NHS was conducted throughout Australia from March 2011 to March 2012. This is the sixth in a series of Australia-wide health surveys conducted by the ABS; previous surveys were conducted in 1989-90, 1995, 2001, 2004-05 and 2007-08. Health surveys conducted by the ABS in 1977-78 and 1983, while not part of the NHS series, also collected similar information. The NNPAS was conducted between May 2011 and June 2012. NNPAS has not been previously collected, however in 1995 there was a National Nutrition Survey which collected similar information on Nutrition.
The 2011-12 Updated Results contains information about:
- three specific long-term health conditions: heart and circulatory conditions, kidney disease and diabetes mellitus;
- health-related aspects of people's lifestyles, such as smoking, Body Mass Index, blood pressure and fruit and vegetable intake; and
- demographic and socioeconomic characteristics.
The statistics presented in this publication are those which were collected as part of the NHS and NNPAS. Further publications from the Australian Health Survey are outlined in the Release Schedule, while the list of data items available from the survey will be available in the Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001).
