HEART AND CIRCULATORY CONDITIONS
The scope of this topic differs according to the particular data aspect being considered.
For data collection purposes, and for data output relating to heart and circulatory conditions as a group of conditions, heart and circulatory conditions were defined broadly to include a range of heart, vascular and related conditions.
Information was obtained for all persons in the NHS (with certain questions only asked of specific groups, as identified below) and persons aged 2 years and over in the NNPAS.
Information about heart and circulatory conditions was collected in both the NHS and the NNPAS surveys. Information on heart and circulatory conditions was first published in the First Results publication based on the NHS only sample of approximately 20,500 people of all ages. Updated results on heart and circulatory conditions for the larger combined, core sample of approximately 32,000 people aged 2 years and over were published in the Updated Results publication. For comparison of heart and circulatory conditions with NHS only items or the 0-1 year old population, the NHS file should be used and similarly for comparison with NNPAS only items, the NNPAS file should be used. However, for the most accurate information for heart and circulatory conditions alone or comparison with other items collected in the core, the core file should be used. For more information on the structure of the AHS, see the Structure of the Australian Health Survey page of this Users' Guide.
Respondents were asked if they had ever been told by a doctor or nurse that they had a heart or circulatory condition. A prompt card showing examples of conditions was provided to respondents. The following predefined condition categories were included on the questionnaire, with provision for interviewers to record three additional conditions if required:
More than one response was allowed.
Please note, while high cholesterol is collected as part of the 'heart and circulatory' module and have data for additional NHS heart and circulatory items, it is classified as being an endocrine condition in the ICD-10.
The use of the prompt card in the questionnaires effectively established this as the most detailed level of information on heart and circulatory conditions available from the survey. Very limited further detail may be available for those conditions recorded in the 'other specify' category.
Respondents were then asked if they currently had any heart or circulatory conditions, including conditions currently controlled by medications, and whether any/which of these conditions had lasted or were expected to last for six months or more. The list of predefined conditions was again used for these questions, and any 'other' responses identified in the initial question.
All NHS respondents aged 45 years or over, and respondents aged 18 to 44 years who specified that they had a current heart or circulatory condition, were asked whether their cholesterol level had been checked in the last 5 years, and if so, whether their cholesterol level had been checked in the last 12 months.
NHS respondents aged 18 years or over were asked whether their blood pressure had been checked in the last two years, and if so, whether it had been checked in the last 12 months, and who usually performs the check (GP, specialist, other health professional, somebody else (e.g. family member), and then whether they had tested their own blood pressure in the last 12 months.
NHS respondents, aged 18 years or over with a current heart or circulatory condition, were also asked whether they took aspirin on a daily basis, and whether this had been on the advice of a doctor.
NHS respondents who reported having a current and long-term heart or circulatory condition were sequenced to the Actions module where they were asked questions about the number of times they had seen a GP, specialist, etc.
NHS respondents were asked in a later module about all medications and health supplements that they were taking, but not in relation to any specific condition. This differs from the 2007-08 survey where questions about medication were asked within the heart and circulatory conditions module.

Points to be considered in interpreting data for this topic include the following:
Comparability with 2007-08
Data for most common items are considered directly comparable between the 2011-12 and 2007-08 surveys.
