Model excludes subjects with diagnosed T2DM. Final model covariates entered in order: dyslipidaemia, BMI
category, physical activity, health insurance, on Rx for cholesterol, family history of T2DM, gender and age.

Model excludes subjects with undiagnosed T2DM. Final model covariates entered in order: family history of T2DM,
on Rx for hypertension, BMI category, on Rx for cholesterol, CVD, dyslipidaemia, alcohol use, gender and age.

Dyslipidaemia: TAG≥1.7 and HDL-C: <1.03 (MALES) <1.29 (FEMALES).
