It should be noted that risk level as defined by the NHMRC is based on regular consumption levels of alcohol, however the NHS does not determine whether consumption in the reference week was more, less or the same as usual consumption.
Drinking status information was also collected for those who did not consume any alcohol in the week prior to interview, categorised as:

ASGC Remoteness Structure
The Australian Standard Geographical Classification (ASGC) Remoteness Structure has 5 categories based on an aggregation of geographical areas which share common characteristics of remoteness, determined in the context of Australia as a whole. These categories are: Major cities of Australia, Inner regional Australia, Outer regional Australia, Remote Australia and Very remote Australia. The five categories are generally aggregated in some way for use in output.
The criteria for these categories are based on the Accessibility/Remoteness Index of Australia (ARIA) developed by the Commonwealth Department of Health and Ageing (DoHA) and the National Key Centre for Social Applications of GIS (GISCA). ARIA measures the remoteness of a point based on the physical road distance to the nearest Urban Centre in each of five size classes. For more information on how ARIA is defined see Information Paper: ABS Views on Remoteness, 2001 (cat. no. 1244.0) and Information Paper: Outcomes of ABS Views on Remoteness Consultation, Australia, Jun 2001 (cat. no. 1244.0.00.001). Also refer to Census Geography Paper 03/01 - ASGC Remoteness Classification - Purpose and Use, available from the ABS web site.

Body Mass Index (BMI)
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity. It is defined as the weight in kilograms divided by the square of the height in metres (kg/m2). The NHS uses the World Health Organisation International Classification of adult underweight, overweight and obesity. Separate cut-off points by sex and age for each grouping are used for children aged 5 to 17 years, based on the corresponding scores for adults 18 years and over for each grouping. For more information, see Chapter 4: Health Risk Behaviours and Appendix 5: Classification of BMI for children.
BMI scores are derived for self-reported and measured height and weight for NHS 2007-08.

For the purposes of condition status items in this survey, also includes high cholesterol. See also Heart, stroke and vascular diseases.
In this survey, co-morbid conditions refers to two or more medical conditions which a respondent has reported as current long-term conditions they have.
See long-term medical condition.
Condition status brings together information about whether or not a person has ever been told by a doctor or nurse they have a condition, whether a condition was current at the time of the survey, and if current whether the condition was long-term (i.e. had lasted or was expected to last for 6 months or more).

A disability or restrictive long-term health condition exists if a limitation, restriction, impairment, disease or disorder, which restricts everyday activities, has lasted, or is expected to last for six months or more.
It is classified by whether or not a person has a specific limitation or restriction. Specific limitation or restriction is further classified by whether the limitation or restriction is a limitation in core activities or a schooling/employment restriction only.
There are four levels of core activity limitation (profound, severe, moderate and mild) which are based on whether a person needs help or has difficulty with, or uses aids or equipment for, self care, mobility or communication. A person's overall level of core activity limitation is determined by their highest level of limitation in these activities.

Exercise level is also available for the week prior to the interview. From these components, an exercise score was derived using factors to represent the intensity of the exercise:
Scores were grouped into the following four categories:
For exercise levels in the last week, scores and time periods are halved.
Inadequate exercise levels are sedentary and low exercise levels. Sedentary refers to sitting in one place for extended periods of time. See also Physical Activity guidelines, and Chapter 4: Health Risk Behaviours for more detail.

Metabolic Equivalent of Task (MET) or intensity values are a measure of the energy expenditure required to carry out exercise, expressed as a multiple of the resting metabolic rate (RMR). MET is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference rate of metabolic rate at rest. MET or intensity values operate as a factor when determining level of exercise. The 2007-08 NHS used the following intensity factors - 3.5 for walking, 5.0 for moderate exercise and 7.5 for vigorous exercise. MET values of physical activities range from 0.9 (sleeping) to 18 (running at 17.5 km/h).

This is a scale of non-specific psychological distress based on 10 questions about negative emotional states in the four weeks prior to interview. The K10 is scored from 10 to 50, with higher scores indicating a higher level of distress. For the NHS, scores are grouped as follows:

This is a combination of Moderate (or 'Risky') and High alcohol risk consumption levels in the long term. See Alcohol risk level.
Four Indexes compiled by the ABS following each population Census. Each index summarises different aspects of the socio-economic condition of areas. The Index of Disadvantage is the SEIFA index most frequently used in health analysis.
The Indexes available for use with 2007-08 NHS data are those compiled from the 2001 and 2006 Census of Population and Housing. The Index scores have been mapped to the NHS sample at both the CD and SLA levels. For further information about the indexes, see Information Paper: Census of Population and Housing - Socio-Economic Indexes for Areas, Australia (ABS Cat no 2039.0).
Self-assessed body mass
Respondents reported assessment of themselves as being of acceptable weight, underweight or overweight.
Self-assessed health status
A person's general assessment of their own health against a five point scale from excellent through to poor.
To determine whether a difference between two survey estimates is a real difference in the populations to which the estimates relate, or merely the product of different sampling variability, the statistical significance of the difference can be tested. This is particularly useful for interpreting apparent changes in estimates over time. The test is done by calculating the standard error of the difference between two estimates and then dividing the actual difference by the standard error of the difference. If the result is greater than 1.96, there are 19 chances in 20 that there is a real difference in the populations to which the estimates relate. For further information see Chapter 7: Data Quality and Interpretation of Results.
