Web update: Health risk factors in 2014–15

Indicator specification

High blood pressure

Percentage of adults who have high blood pressure

Percentage of adults who have uncontrolled high blood pressure

Indicator description and calculation
Type of measurement Percentage, reported at one decimal place.
Calculation 100 x (numerator ÷ denominator)
Numerator

Total high blood pressure:

Number of adults who had measured high blood pressure and/or are taking medication for high blood pressure.

Uncontrolled high blood pressure:

Number of adults who had measured high blood pressure, irrespective of whether they were taking medication for high blood pressure.

Notes:

  • Participants were included in the analysis if they were aged 18 years and over.
  • Participants in the ABS NHS 2014–15 had their blood pressure measured. Participants were also asked if they took medication for high blood pressure.
  • numerator was calculated as the sum of calibrated sample weights for adults who responded that they had the characteristics of interest and who were enumerated within the particular PHN area.
Denominator

Total population of adults in-scope of NHS 2014–15.

Note:

  • The denominator was calculated as the sum of calibrated sample weights for adults who were enumerated within the PHN area.
Disaggregation

PHN areas, including:

  • Metropolitan PHN areas
  • Regional PHN areas.

Refer to the ‘Presentation of results’ section for more detail.

Confidence intervals As an indication of the accuracy of estimates, 95% confidence intervals were produced. These were calculated by the ABS using standard error estimates of the proportion.

Insufficient physical activity

Percentage of adults who perform insufficient weekly physical activity

Indicator description and calculation
Type of measurement Percentage, reported at one decimal place.
Calculation 100 x (numerator ÷ denominator)
Numerator

Number of adults who did not meet the physical activity guidelines:

Adults aged 18–64:

150 minutes or more of moderate or 75 minutes or more of vigorous physical activity on 5 or more sessions in a week.

Australians aged 65 or over:

30 minutes or more of physical activity per day on 5 or more days in a week.

Notes:

  • Participants were included in the analysis if they were aged 18 years and over.
  • Participants in the ABS NHS 2014–15 were asked about duration, sessions (18–64 years) and days (65+ years)
  • The numerator was calculated as the sum of calibrated sample weights for adults who responded that they had the characteristics of interest and who were enumerated within the particular PHN area.
Denominator

Total population of adults in-scope of NHS 2014–15.

Note:

  • The denominator was calculated as the sum of calibrated sample weights for adults who were enumerated within the PHN area.
Disaggregation

PHN areas, including:

  • Metropolitan PHN areas
  • Regional PHN areas.

Confidence intervals As an indication of the accuracy of estimates, 95% confidence intervals were produced. These were calculated by the ABS using standard error estimates of the proportion.

Lifetime risky alcohol consumption

Percentage of adults who consume more than two standard drinks per day on average

Indicator description and calculation
Type of measurement Percentage, reported at one decimal place.
Calculation 100 x (numerator ÷ denominator)
Numerator

Number of adults who consumed 2 or more standard drinks per day, on average over the three most recent days that they had consumed alcohol.

Notes:

  • Participants were included in the analysis if they were aged 18 years and over.
  • Participants in the ABS NHS 2014–15 were asked about alcohol consumption on the three most recent days that they had consumed alcohol in the last week.
  • The numerator was calculated as the sum of calibrated sample weights for adults who responded that they had the characteristics of interest and who were enumerated within the particular PHN area.
Denominator

Total population of adults in-scope of NHS 2014–15.

Note:

  • The denominator was calculated as the sum of calibrated sample weights for adults who were enumerated within the PHN area.
Disaggregation

PHN areas, including:

  • Metropolitan PHN areas
  • Regional PHN areas.
