Bold values are statistically significant (p < 0.05).
Model 1: unadjusted model; model 2: models adjusted for age and sex; model 3: model 2+adjusted for chronic diseases; model 4: model 3+adjusted for health behaviours.
*Odds of prediabetes (ie, HbA1c 5.7–6.4%), compared to normal HbA1c levels (ie, HbA1c≤5.6%).
†Odds of suboptimal HDL levels, that is, HDL<1.0 mmol/L (men) or <1.3 mmol/L (women), compared to optimal HDL levels, that is, HDL≥1.0 mmol/L (men) or ≥1.3 mmol/L (women).
HbA1c, glycated haemoglobin; HDL, high-density lipoprotein.
