GLOSSARY

The definitions used in this survey are not necessarily identical to those used for similar items in other collections. Additional information about the items is contained in the 2007-08 National Health Survey (NHS); Users' Guide, which will be available on the ABS web site <https://www.abs.gov.au> from September 2009.

Alcohol consumption risk level

Alcohol consumption risk levels in the long term were derived from the average daily consumption of alcohol by persons aged 15 years and over for 3 days of the week prior to interview and are grouped into relative risk levels as defined by the National Health and Medical Research Council (NHMRC) in 2001 as follows:

ALCOHOL RISK LEVEL(a)

Consumption per day
Risk level Males Females

Low risk 50 mLs or less 25 mLs or less
Risky More than 50 mLs, up to 75 mLs More than 25 mLs, up to 50 mLs
High risk More than 75 mLs More than 50 mLs

(a) One standard drink contains 12.5 mLs of alcohol.


It should be noted that risk level as defined by the NHMRC is based on regular consumption levels of alcohol where as estimates of risk from the NHS do not take into account whether consumption in the reference week was more, less or the same as usual.

The level of long term risk is associated with regular daily patterns of drinking. Drinking status information was also collected for those who did not consume any alcohol in the 7 days prior to interview. Categorised as:
  • Last consumed more than one week to less than 12 months ago;
  • Last consumed 12 months or more ago; and
  • Never consumed.

Ancillary cover

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).

Arthritis

Arthritis is characterised by an inflammation of the joints often resulting in pain, stiffness, disability and deformity.

Asthma

A chronic disease marked by episodes of wheezing, chest tightness and shortness of breath associated with widespread narrowing of the airways within the lungs and obstruction of airflow. To be current, symptoms of asthma or treatment for asthma must have occurred in the last 12 months.

Bodily pain

Indication of the severity of any bodily pain that the respondent had experienced (from any and all causes) during the last 4 weeks. This is a self-assessment from the SF36 international instrument.

Body Mass Index (BMI)

Calculated from height and weight information, using the formula weight (kg) divided by the square of height (m). To produce a measure of the prevalence of underweight, normal weight, overweight or obesity in adults, BMI values are grouped according to the table below which allows categories to be reported against both the World Health Organization (WHO) and National Health and Medical Research Council (NHMRC) guidelines.

BODY MASS INDEX, ADULT


Underweight Less than 18.5
Normal range 18.5 to less than 20.0
20.0 to less than 25.0
Overweight 25.0 to less than 30.0
Obese 30.0 and greater



Separate BMI classifications were produced for children. BMI scores were created in the same manner described above but also took into account the age and sex of the child. There are different cutoffs for BMI categories (underweight/normal combined, overweight or obese) for male and female children. These categories differ to the categories used in the adult BMI classification and follow the scale provided in Cole TJ, Bellizzi MC, Flegal KM and Dietz WH, Establishing a standard definition for child overweight and obesity worldwide: international survey, BMJ 2000; 320. For a detailed list of the cutoffs used to calculate BMI for children see 2007-08 National Health Survey Users' Guide cat. no. (4363.0.55.001).

Cause of condition

Asked in respect of all the current long term conditions which the respondent had previously reported. This refers to the respondent's perception of whether the condition was the result of an injury.

Conditions

See long term medical condition.

Current daily smoker

A current daily smoker is an adult who reported that they regularly smoked one or more cigarettes, cigars or pipes per day. See also Smoker status.

Days away from work or study

Refers to days on which the respondent was away from work, school or other educational institution for at least half the day. Absences included days away due to a respondent’s own illness or injury.

Diabetes mellitus

A chronic condition in which blood glucose levels become too high due to the body producing little or no insulin, or not using insulin properly.

Dietary guidelines

As specified by the National Health and Medical Research Council (NHMRC) for fruit and vegetable consumption. See Usual intake of fruit and Usual intake of vegetables.

Disability status

A disability or restrictive long term health condition exists if a limitation, restriction, impairment, disease or disorder, has lasted, or is expected to last for six months or more, and which restricts everyday activities.

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, has difficulty, or uses aids or equipment with any of the core activities (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.

Employed

Persons aged 15 years and over who had a job or business, or who undertook work without pay in a family business for a minimum of one hour per week. Includes persons who were absent from a job or business. See also Unemployed and Not in the labour force.

Exercise level

Based on frequency, intensity (i.e. walking, moderate exercise and vigorous exercise) and duration of exercise (for fitness, recreation or sport) in the two weeks prior to the interview. From these components, an exercise score was derived using factors to represent the intensity of the exercise:
  • 3.5 for walking
  • 5.0 for moderate exercise
  • 7.5 for vigorous exercise

Scores were grouped into the following four categories:

LEVEL OF EXERCISE

Category

Very low(a) Score less than 100
Low Score of 100 to less than 1,600
Moderate Score of 1,600 to 3,200, or score of more than 3,200 but with less than 2 hours of vigorous exercise.
High Score of more than 3,200 plus 2 hours or more of vigorous exercise

(a) Includes no exercise.


Inadequate exercise levels are sedentary and low exercise levels. Sedentary refers to sitting in one place for extended periods of time.
