The definitions used in this survey are not necessarily identical to those used for similar items in other collections. Additional information about the items and their definitions are contained in the 2001 National Health Survey; Users' Guide, available from December 2002.
Age standardisation is used in this publication to allow the comparison of populations with different age structures. A standard age composition is used, in this case the age composition of the 2001 NHS benchmark population of Australia as at 30 June 2001. The age standardised estimate or proportion is that which would have prevailed at another point in time or other geographic area should the actual population have the standard age composition.
Alcohol risk level
The adult was divided into risk levels determined by their estimated average daily alcohol consumption in the 7 days prior to interview. Average daily consumption in the previous 7 days was estimated using two components:
Risk levels are based on the NHMRC1 risk levels for harm in the long term, and assumes the level of alcohol consumption is typical. The average daily consumption of alcohol associated with the risk levels is as follows:
1 National Health and Medical Research Council (NHMRC), 2001, Australian Alcohol Guidelines: Health Risks and Benefits (www.nhmrc.gov.au).
Drinking status information was also collected for those who did not consume any alcohol in the 7 days prior to interview:
Any cover provided by private insurance organisations for health-related services other than medical or hospital cover (e.g. physiotherapy, dental, optical, chiropractic and ambulance).
Body Mass Index (BMI)
Calculated from self-reported height and weight information, using the formula weight (kg) divided by the square of height(m). To produce a measure of the prevalence of overweight or obesity in adults, BMI values are grouped according to the table below which allows categories to be reported against both WHO and NHMRC guidelines.
Based on the reported period that a baby was breastfed, and the ages at which other foods were introduced into the regular diet, breastfeeding status refers to the level of breastfeeding at a given age:
Days out of role
Days away from work or school/study, and other days of reduced activity due to own illness or injury.
Refers to days on which the respondent was away from work, school or other educational institution (as appropriate) for at least half the day. Absences included days away due to a respondent's own illness or injury, or to care for another person with an illness or injury. Employed persons away from both work and school/study have been included under days away from work only.
Includes dentist, orthodontist, dental nurse, dental technician and dental mechanic.
People who reported that they had worked in a job, business or farm during the reference week (the full week prior to the date of interview); or that they had a job in the reference week but were not at work.
Based on frequency, intensity (i.e. walking, moderate exercise and vigorous exercise) and duration of exercise (for recreation, sport or fitness) in the 2 weeks prior to interview. From these components, an exercise score was derived using factors to represent the intensity of the exercise. Scores were grouped for output as follows:
Includes Health Care Card, Pensioner Concession Card, Commonwealth Seniors Health Card and treatment entitlement cards issued by the Department of Veterans' Affairs.
Self assessed change in overall health relative to 12 months prior to interview.
Highest educational qualification
The level of the highest educational qualification obtained since leaving school.
Health insurance provided by private insurance organisations to cover all or part of the costs of private accommodation in a public hospital, charges for private hospital treatment and care in a public hospital by a doctor of the patient's choice.
Based on usual residents of households, as reported at the time of the survey.
Immunisation status is defined as the degree to which the recommended course of vaccinations for a particular disease has been received (as appropriate to the age of the child). The NHMRC Standard Childhood Vaccination Schedules were used to derive immunisation status of children. Immunisation status is categorised as:
Incidence refers to the number of new cases of a particular characteristic, such as cancer, which occur within a certain period. This differs from prevalence, which refers to the number of cases of a particular characteristic that are present in a population at one point in time. Incidence and prevalence can also be presented as proportions of the population of interest.
Income of income unit
An income unit may comprise one person or group of related persons (de facto or registered marriage or parent/dependent child relationship) within a household whose command over income is assumed to be shared. An income unit may therefore include the partner (for couples), all children aged less than 15 years, and children aged 15-24 years provided they are unmarried, full-time students and do not have dependents of their own. In this survey, income unit income is the sum of the respondent's cash income and the cash income of their spouse/partner (where applicable). The income of any children within the units is not included.
Index of relative socioeconomic disadvantage
One of 5 of the Socio-Economic Indexes for Areas (SEIFAs) compiled by the ABS following each population Census. Each of the indexes summarise different aspects of the socioeconomic condition of areas; the index of relative socioeconomic disadvantage includes attributes such as low income, low educational attainment, high unemployment and jobs in relatively unskilled occupations. The index refers to the area (the Census Collector's District) in which a person lives, not to the socioeconomic situation of the particular individual. The index used in this publication were those compiled following the 1996 Census. For further information about the SEIFAs see Information Paper; 1996 Census of Population and Housing: SocioEconomic Indexes for Areas (cat. no. 2039.0).
In the labour force
People who, during the reference week, were employed or unemployed, as defined (See also Labour force status).
See Psychological distress.
Labour force status

Long term condition
A condition which in the respondent's opinion has lasted for 6 months or more, or which he or she expects will last for 6 months or more. Some conditions reported were assumed to be long term conditions. These included asthma, cancer, diabetes insipidus, diabetes mellitus types 1 and 2, rheumatic heart disease, heart attack and stroke.

Other health professional (OHP)
Any medication used in the 2 weeks prior to interview for asthma, cancer, heart and circulatory conditions or diabetes/high sugar levels, other than medications identified by respondents as vitamins or minerals, or natural or herbal medications. See also type of medication below.
The number of cases of a particular characteristic (e.g. a specific long term condition such as cancer) that are present in a population at one point in time. This differs from incidence, which refers to the number of new cases of a particular characteristic, such as cancer, which occur within a certain period. Prevalence and incidence can also be presented as proportions of the population of interest.
Derived from the Kessler Psychological Distress Scale-10 items (K-10). This is a scale of non-specific psychological distress based on 10 questions about negative emotional states in the 4 weeks prior to interview. The K10 is scored from 10 to 50, with higher scores indicating a higher level of distress; low scores indicate a low level of distress. In this publication scores are grouped as follows:
Self assessed body mass

Type 2 - Non-insulin dependent diabetes. This is a condition where the body's cells do not respond to insulin in the normal way. Type 2 diabetes can appear at any age. It is the most common form of diabetes mellitus. People with Type 2 may go on to need regular insulin injections.
