COMPARISON OF FIRST RESULTS AND UPDATED RESULTS

Results in this publication are from a combined data file of both the National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) and the National Aboriginal and Torres Strait Islander Nutrition and Physical Activity Survey (NATSINPAS), and relate to the following topics:

• Self-assessed health status
• Diabetes and high sugar levels
• Heart and circulatory disease(s)
• Kidney disease
• Overweight and obesity
• Tobacco smoking
• Daily intake of fruit and vegetables
• Measured high blood pressure
• Waist circumference and waist-to-hip ratio
• Labour force characteristics
• Highest educational attainment.

For a summary of data updates and additions between the First Results publication and this publication, see Table 22: First Results to Updated Results—comparability of tables in the Downloads section.

Information on most of these topics was first published from the NATSIHS sample only (9,300 Aboriginal and Torres Strait Islander people) in the Australian Aboriginal and Torres Strait Islander Health Survey: First Results (4727.0.55.001). The results in this publication are based on the full AATSIHS sample (NATSIHS and NATSINPAS combined) of approximately 12,900 Aboriginal and Torres Strait Islander people. For more information on the structure of the 2012–13 AATSIHS, see Structure of the Australian Aboriginal and Torres Strait Islander Health Survey.

New information presented in this release includes:

• BMI by Indigenous status for children aged 2–14 years
• Labour force status by Indigenous status for people aged 15–64 years
• Highest educational attainment by Indigenous status for people aged 20 years and over
• Self-reported hypertensive disease and measured blood pressure by Indigenous status for people aged 18 years and over.

The differences between national and other aggregate level estimates from the First Results (published on 27 November, 2013) and the Updated Results are minimal. The following table provides a comparison of key estimates and the associated Margin of Error (MOE) at the 95% confidence level. There is no statistically significant difference between the First Results and Updated Results for all but one of the key indicators presented below. The exception is Hypertensive disease (up from 5.0% to 5.8%). Note that when comparing data on Hypertensive disease on a consistent basis (that is, for persons aged 2 years and over) this difference is not statistically significant.

	First Results (%)	First Results (MOE ±)	Updated Results (%)	Updated Results (MOE ±)
Current daily smoker(a)	41.0	2.0	41.6	1.8
Overweight or obese(a)	65.6	2.2	66.0	1.6
Inadequate daily fruit consumption(a)(b)	57.2	2.2	58.0	1.5
Inadequate daily vegetable consumption(a)(b)	95.1	0.9	95.2	0.7
Diabetes/high sugar levels(c)	8.2	0.7	8.6	0.6
Heart, stroke and vascular disease(c)	3.8	0.6	3.9	0.5
Hypertensive disease(c)	5.0	0.6	5.8	0.5
Kidney disease(c)	1.7	0.4	1.8	0.3
Measured high blood pressure(a)	20.3	1.9	20.4	1.4
Self-assessed health: Excellent/Very Good(a)	39.2	1.9	39.3	1.5
(a) Persons aged 15 years and over. (b) Based on the 2013 NHMRC Guidelines. For more information, see Usual daily intake of fruit and Usual daily intake of vegetables in the Glossary. (c) First Results estimates are for all persons and Updated Results are for persons aged 2 years and over.

The main change between the First Results and the Updated Results is to information on long-term conditions. The Updated Results are for Aboriginal and Torres Strait Islander people aged 2 years and over, while First Results data are for Aboriginal and Torres Strait Islander people of all ages, including those aged less than 2 years. The table below compares data from First Results and Updated Results for the selected long-term health conditions using a consistent population, that is, Aboriginal and Torres Strait Islander people aged 2 years and over. There are no statistically significant differences between the First Results and Updated Results for any of these long-term health conditions.

	First Results (%)	First Results (MOE ±)	Updated Results (%)	Updated Results (MOE ±)
Diabetes/high sugar levels	8.6	0.8	8.6	0.6
Heart, stroke and vascular disease	4.0	0.6	3.9	0.5
Hypertensive disease	5.2	0.6	5.8	0.5
Kidney disease	1.8	0.4	1.8	0.3

Although there are no statistically significant differences between the First Results and Updated Results data for the key indicators, the full AATSIHS sample is approximately 1.4 times the NATSIHS sample and may therefore produce more accurate estimates for topics included in the core content. In addition, this release also includes previously unpublished data on the educational attainment and labour force characteristics of Aboriginal and Torres Strait Islander people using the full AATSIHS sample.
