RESUMEN
AIM: The present study aimed to validate the Finnish Type 2 Diabetes Risk Score (FINDRISC) questionnaire for its ability to predict the presence of any glucose homoeostasis abnormalities and the metabolic syndrome (MetS) in the Greek population. METHODS: Validation was performed on a sample of individuals who had agreed to participate in a screening program for type 2 diabetes (T2D) prevention (the Greek part of the DE-PLAN study), using both FINDRISC and oral glucose tolerance tests (OGTT). Impaired fasting glucose (IFG) was defined as a fasting plasma glucose level of 6.1-6.9 mmol/L, and impaired glucose tolerance (IGT) as a 2-h plasma glucose of 7.8-11.0 mmol/L. The predictive value of the FINDRISC was cross-sectionally evaluated using the area under the receiver operating characteristic (AUROC) curve method. RESULTS: A total of 869 individuals (379 men, aged 56.2 ± 10.8 years) were screened from the general population living in the city and suburbs of Athens. OGTT revealed the presence of unknown diabetes in 94 cases (10.8%), IFG in 85 (9.8%) and IGT in 109 (12.6%). The sensitivity of a FINDRISC score greater or equal to 15 (45% of the population) to predict unknown diabetes was 81.9% and its specificity was 59.7%. The AUROC curve for detecting unknown diabetes was 0.724 (95% CI: 0.677-0.770). For any dysglycaemia, the AUROC curve was 0.716 (0.680-0.752) while, for detection of the MetS, it was 0.733 (0.699-0.767). CONCLUSION: The FINDRISC questionnaire performed well as a screening tool for the cross-sectional detection of unknown diabetes, IFG, IGT and the MetS in the Greek population.

AIMS: To report our experience of implementing the first community-based lifestyle intervention programme to detect high-risk individuals and prevent the development of Type 2 diabetes mellitus (T2DM) in a general population sample in Athens, Greece (the DE-PLAN Study). METHODS: The Finnish Type 2 Diabetes Risk Score (FINDRISC) questionnaire was distributed to 7900 people at workplaces and primary-care centres. High-risk individuals were invited to receive an oral glucose tolerance test (OGTT) and, after excluding persons with diabetes, to participate in a 1-year intervention programme, based on bimonthly sessions with a dietitian. RESULTS: Three thousand, two hundred and forty questionnaires were returned; 620 high-risk individuals were identified and 191 agreed to participate. Recruitment from workplaces was the most successful strategy for identifying high-risk persons, enrolling and maintaining them throughout the study. The 125 participants who fully completed the programme (66 did not return for a second OGTT) lost on average 1.0+/-4.7 kg (P=0.022). Higher adherence to the intervention sessions resulted in more significant weight loss (1.1+/-4.8 vs. 0.6+/-4.6 kg for low adherence). Persons with impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) at baseline lost more weight than those with normal glucose tolerance (1.5+/-4.8 vs. -0.2+/-4.5 kg). The percentage of people with any type of dysglycaemia (IFG/IGT) was lower after the intervention (68.0% at baseline vs. 53.6% 1 year later, P=0.009); 5.6% developed diabetes. CONCLUSIONS: The implementation of a lifestyle intervention programme to prevent T2DM in the community is practical and feasible, accompanied by favourable lifestyle changes. Recruitment from workplaces was the most successful strategy.

BACKGROUND/OBJECTIVES: Earlier studies have shown that the addition of vinegar in a carbohydrate-rich meal lowers glucose and insulin response in healthy individuals. The mechanism of how this is accomplished, however, remains unclear. The aim of this study is to examine the effect of vinegar on glucose and insulin response in patients with type II diabetes (T2D) in relation to the type of carbohydrates consumed in a meal. SUBJECTS/METHODS: Sixteen patients with T2D were divided into two groups, matched for age, gender and HbA(1c). Patients in the first group (group A) were given a high-glycaemic index (GI) meal (mashed potatoes and low-fat milk) on two different days, with and without the addition of vinegar, respectively. In the second group (group B), patients were given an isocaloric meal with the same nutrient composition, but low GI (whole grain bread, lettuce and low-fat cheese). Postprandial plasma glucose and insulin values were measured every 30 min for 2 h. RESULTS: In group A, the incremental area under the curve of glucose (GiAUC(120)) was lower after the addition of vinegar (181+/-78 mmol min/l vs 311+/-124 mmol min/l, P=0.04). The iAUC of insulin (IiAUC(120)) was also reduced, but the difference was of marginal statistical significance (2368+/-1061 microU min/ml vs 3545+/-2586 microU min/ml, P=0.056). In group B, the addition of vinegar did not affect either the GiAUC(120) (229+/-38 mmol min/l vs 238+/-25 mmol min/l, P=0.56) or the IiAUC(120) (2996+/-1302 microU min/ml vs 3007+/-1255 microU min/ml, P=0.98). CONCLUSIONS: We conclude that the addition of vinegar reduces postprandial glycaemia in patients with T2D only when it is added to a high-GI meal.
