Abstract

Objective: To compare the effectiveness of different approaches to nutrition education in diabetes self-management education and support (DSME/S). Methods: We randomized 150 adults with type 2 diabetes to either certified diabetes educator (CDE)-delivered DSME/S with carbohydrate gram counting or the modified plate method versus general health education. The primary outcome was change in HbA1C over 6 months. Results: At 6 months, HbA1C improved within the plate method [-0.83% (-1.29, -0.33), P 1C from baseline between the control and intervention groups was not significant at 6 months (carbohydrate counting, P =0.36; modified plate method, P =0.08). In a pre-specified subgroup analysis of patients with a baseline HbA1C 7-10%, change in HbA1C from baseline improved in the carbohydrate counting [-0.86% (-1.47, -0.26), P =0.006] and plate method groups [-0.76% (-1.33, -0.19), P =0.01] compared to controls. Conclusion: CDE-delivered DSME/S focused on carbohydrate counting or the modified plate method improved glycemic control in patients with an initial HbA1C between 7 and 10%. Practice implications: Both carbohydrate counting and the modified plate method improve glycemic control as part of DSME/S.
