Notes: a Less than 1% missing values for age, marital status, remoteness, SEIFA, and ever being a smoker. b Less than 4% missing values for born in Australia, work status, fruit intake, vegetable intake, alcohol consumption, and BMI. c Annual household income has 25% missing values, including “did not disclose”. Duration of diabetes has 25% missing values, whereas the missing value for psychological stress is 17.5%. + Remoteness of residence is derived from the Accessibility-Remoteness Index of Australia scores from 2006 (Australian Government Department of Health). These scores were calculated based upon distance by road to the nearest population centre where services can be obtained. The Australian Bureau of Statistics uses this score to classify different regions into major cities, inner regional, outer regional, remote, and very remote. ^ Socioeconomic status was assessed by index of relative socioeconomic disadvantage (IRSD), which is one of indices of the Socioeconomic Indexes for Areas (SEIFA) (Australian Bureau of Statistics). ^^ “Other” category in work status included individuals who were sick, disabled, students, or unemployed. ^^^ DVA denotes Department of Veterans’ Affairs. DVA or concession card holders may receive higher discounted health services and medication. Participants were asked, “In the last month have you been treated for high blood cholesterol?” § Psychological distress is categorised according to the Australian Bureau of Statistics classification. The Kessler-10 (K10) scale was used to categorise psychological distress into three groups: “low (10–15)”, “moderate (16–21)”, and “high/very high (22–50)”.
