a Defined as having two or more individual health risk behaviours.
b Estimates for 2007 are not reported because the survey split questionnaire design used in this year was not consistent with other years.
c Estimates adjusted for age and sex structure of NSW population and probability of selection for inclusion in the survey; estimates standardised to age and sex structure of NSW population for 2012; estimates exclude persons with responses “Don’t know”, “Refused” or “Not asked”.
d Reference group is the least disadvantaged group.
e For education, includes persons with at most a school certificate; for IRSD, includes persons who belonged to the 5th quintile.
f For education, includes persons who completed a university degree or higher; for IRSD, includes persons who belonged to the 1st quintile.
