Variables with < 0.10 eligible on univariate analysis for entry into model. Backward stepwise elimination used, < 0.05 considered significant. Categorical variables dummy coded using indicated reference groups. Only significant predictors listed were included in the final model
* Risk stratification: low risk = 0.44% prevalence; moderate risk = 4.1% prevalence; high risk = 11.1% prevalence for undiagnosed diabetes
