Cardiometabolic profile of people screened for high risk of type 2 diabetes in a national diabetes prevention programme (FIN-D2D).

AIMS: To study screening of high-risk individuals as part of a national diabetes prevention programme in primary health care settings in Finland between 2003 and 2007, and evaluate the cardiometabolic risk profile of persons identified for intervention.
METHODS: High-risk individuals were identified by the Finnish Diabetes Risk Score (FINDRISC), history of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), cardiovascular disease (CVD), or gestational diabetes. Participants subsequently underwent an oral glucose tolerance test. CVD morbidity risk was estimated by the Framingham Study Risk Equation and CVD mortality risk by the Systematic Coronary Risk Evaluation Formula (SCORE).
RESULTS: A high-risk cohort of 10,149 (of whom 30.3% men) was identified (mean age 54.7 for men, 53.0 for women). Altogether 18.8% of men and 11.5% of women had screen-detected diabetes. In total 68.1% of men and 49.4% of women had abnormal glucose tolerance (IFG, IGT or screen-detected diabetes). Furthermore, 43.2% and 41.5% of men, and 13.3% and 11.3% of women, respectively, had a high predicted risk of CVD morbidity or mortality.
CONCLUSION: Prevalence of dysglycemia including undiagnosed diabetes and the predicted risk for CVD was alarmly high in the identified high-risk cohort, particularly in men.
