Prevalence (univariate/bivariate) estimations were performed using separate logistic regression models. Ref. denotes reference categories for statistical comparisons. For age and educational level variables, design-adjusted Wald tests were used for testing if the linear combination of coefficients was different from zero.
IFG, impaired fasting glucose.
