Impact of a Community Lifestyle Intervention Pilot Program (PREPARE) for Adults Diagnosed with Prediabetes in London, Ontario

Abstract

s / Can J Diabetes 37 (2013) S13eS84 S69 Objective: To examine the association between adherence to a Mediterranean-style diet and the cardiometabolic profile of patients with T1D. Methods: These preliminary analyses included 67 patients for whom waist circumference, A1C, blood pressure and lipid profile values weremeasured. Insulin sensitivity was estimated (estimated glucose disposal rate; eGDR). The MedDiet score was based on 3day food records and included 11 components (whole grain products, vegetables, fruits, legumes/nuts, olive oil, dairy products, fish, poultry, eggs, sweets and red/processed meats; possible score ranges from 0 to 44). Results: Patients (50% men) were 43.4 13.3 years old with a mean waist circumference of 87.2 10.9 cm, a mean A1C of 7.9 1.1% and a mean MedDiet score of 20.9 4.7. Adherence to the MedDiet did not differ between men and women. The MedDiet score was negatively correlated with waist circumference (r1⁄4e0.30, p1⁄40.01) and systolic blood pressure (r1⁄4e0.29, p1⁄40.02), and tended toward a significant association with eGDR (r1⁄40.22, p1⁄40.08). Patients with a lower MedDiet score (lowest tertile; score 18) had a higher waist circumference (91.1 12.3 vs. 84.9 9.6 cm, p1⁄40.03) and higher systolic and diastolic blood pressures (119 14 vs. 110 11, p1⁄40.003; 72 7 vs. 68 8, p1⁄40.03). No difference was observed for A1C or lipid profile variables. Conclusion: These results suggest potential benefits of a MedDiet for patients with T1D and support the necessity to test this dietary approach for this population.
