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 Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001) scheduled for release in November 2012.

Adult

A respondent aged 18 years or over.

Age standardisation

Age standardisation is a way of allowing comparisons between two or more populations with different age structures, in order to remove age as a factor when examining relationships between variables. For example, the age structure of the population of Australia is changing over time. As the prevalence of a particular health condition (for example, arthritis) may be related to age, any increase in the proportion of people with that health condition over time may be due to real increases in prevalence or to changes in the age structure of the population over time or to both. Age standardising removes the effect of age in assessing change over time or between different populations.

Note that proportions quoted in commentary in this publication are not age-standardised, however, those presented in datacube Table 1 include age standardised rates for all years and both age standardised and non-age standardised rates for 2011-12. Data in this table is age standardised to the 2001 Australian population.

Alcohol consumption risk level

Alcohol consumption risk levels in this publication have been assessed using the 2001 and 2009 National Health and Medical Research Council (NHMRC) guidelines for the consumption of alcohol.

Risk in the longer term (2001 guidelines) and lifetime risk (2009 guidelines) was assessed using average daily consumption of alcohol for persons aged 15 years and over, derived from the type, brand, number and serving sizes of beverages consumed on the three most recent days of the week prior to interview, in conjunction with the total number of days alcohol was consumed in the week prior to interview.

Risk in the short term (2001 guidelines) and single occasion risk (2009 guidelines) was assessed using questions on the number of times in the last 12 months a person's consumption exceeded specified levels.

Alcohol consumption status information was also collected for persons 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.

For more detailed information on the 2001 NHMRC guidelines, see the Australian Alcohol Guidelines: Health Risks and Benefits and for the 2009 guidelines, see the Australian Guidelines to Reduce Health Risks from Drinking Alcohol and Frequently Asked Questions.

For a detailed explanation of the method used to measure alcohol consumption in ABS health surveys, see Alcohol Consumption in Australia: A Snapshot, 2007-08 (cat. no. 4832.0.55.001).

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.

Back pain/problems, disc disorder

Includes back pain or other back problems, such as sprains, strains or joint pain, as well as disc disorders, such as slipped discs or disc degeneration. Excludes arthritis and osteoporosis (as they are reported in their own separate classification), and also excludes sciatica, curvature of the spine and soft tissue disorders.

Blood pressure

See High blood pressure, Diastolic blood pressure and Systolic blood pressure.

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. Data was collected from respondents aged 18 years and over.

Body Mass Index (BMI)

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight and obesity. It is 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, Adults

CategoryRange

UnderweightLess than 18.50
Normal range18.50 —19.99
20.00 — 24.99
Overweight25.00 — 29.99
Obese30.00 or more


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 the Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001) scheduled for release in November 2012.

Child

A person aged 0-17 years.

Chronic obstructive pulmonary disease (COPD)

Chronic obstructive pulmonary disease (COPD), a serious long-term lung disease, is the occurrence of chronic bronchitis or emphysema, a pair of commonly co-existing diseases of the lungs in which airways become narrowed. It mainly affects older people and is often difficult to distinguish from asthma.

Conditions

See long-term medical condition.

Current daily smoker

A current daily smoker is a respondent who reported at the time of interview that they regularly smoked one or more cigarettes, cigars or pipes per day. See also Smoker status.

Deafness

Includes partial or total loss of hearing.

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.

Diastolic blood pressure

Measures the pressure in the arteries as the heart relaxes before the next beat. It is the lower number of the blood pressure reading.

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 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 (that is, walking, moderate exercise or vigorous exercise) and duration of exercise (for fitness, recreation or sport) in the one week prior to interview. From these, an exercise score was derived using factors to represent the intensity of the exercise.

For more information see the Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001) scheduled for release in November 2012.

High blood pressure

A measured blood pressure reading of 140/90 mmHg (millimetres of mercury) or higher. Data on high blood pressure in this publication refer to measured blood pressure only, and do not take into account whether people who might otherwise have high blood pressure are managing their condition through the use of blood pressure medications.

Household

A household is defined as one or more persons, at least one of whom is at least 15 years of age, usually resident in the same private dwelling. In this survey, only households with at least one adult (aged 18 years and over) were included.

Household structure

High Sugar Levels

High sugar levels in blood or urine.

Hypertensive disease

Also known as hypertension or high blood pressure, hypertensive disease is a chronic medical condition in which the blood pressure in the arteries is elevated, requiring the heart to work harder than normal to circulate blood through the blood vessels. Hypertension is a major risk factor for strokes and myocardial infarction (heart attacks) as well as several other medical conditions.

Index of Relative Socio-Economic Disadvantage

This is one of four Socio-Economic Indexes for Areas (SEIFA) compiled by ABS following each Census of Population and Housing. The indexes are compiled from various characteristics of persons resident in particular areas: the Index of Relative Socio-Economic Disadvantage summarises attributes such as low income, low educational attainment, high unemployment and jobs in relatively unskilled occupations. A lower Index of Relative Socio-Economic Disadvantage quintile (e.g. the first quintile) indicates relatively greater disadvantage and a lack of advantage in general. A higher Index of Relative Socio-Economic Disadvantage (e.g. the fifth quintile) indicates a relative lack of disadvantage and greater advantage in general. For further information about SEIFA see the Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001) scheduled for release in November 2012.

Glasses, contact lenses and laser techniques are used to correct long sightedness.

Long-term medical condition (or Long-term health condition)

A medical condition (illness, injury or disability) which has lasted at least six months, or which the respondent expects to last for six months or more. Some reported conditions were assumed to be long-term, including asthma, arthritis, cancer, osteoporosis, diabetes, sight problems, rheumatic heart disease, heart attack, angina, heart failure and stroke. Rheumatic heart disease, heart attack, angina, heart failure and stroke were also assumed to be current.

  • Are permanently unable to work; or
  • Have never worked and never intend to work.

Osteoporosis

A condition that thins and weakens bone mineral density, generally caused by loss of calcium, which leads to increased risk of fracture. Data was collected from persons aged 15 years and over plus younger respondents who reported having gout, rheumatism or arthritis.

Psychological distress

Derived from the Kessler Psychological Distress Scale (K10). This is a scale of non-specific psychological distress based on 10 questions about negative emotional states in the past 30 days. 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:
  • Low levels of distress (10-15);
  • Moderate levels of distress (16-21);

Short sightedness

Short sightedness (or myopia) is a common condition of the eye where the light that comes into the eye does not directly focus on the retina but in front of it, causing the image of a distant object to be out of focus, but that of a close object to be in focus. Glasses, contact lenses and laser techniques are used to correct short sightedness.

Smoker status

The extent to which a respondent was smoking at the time of interview, and refers to regular smoking of tobacco, including manufactured (packet) cigarettes, roll-your-own cigarettes, cigars and pipes, but excludes chewing tobacco and smoking of non-tobacco products. Categorised as:

Systolic blood pressure

Measures the pressure in the arteries as the heart pumps blood during each beat. It is the higher number of the blood pressure reading.

Type of conditions

All reported long-term medical conditions were coded to a classification developed by the ABS for use in the 2001 National Health Survey, which is based on the tenth revision of the International Classification of Diseases and Health Related Problems (ICD-10).
