This 24 month study evaluated the effect of dietitian coaching combined with minimal endocrinologist follow up on the glycemic control and cardiovascular risks of diabetic participants, compared with conventional endocrinologist follow up. Participants with type 1 or type 2 diabetes were assigned to either the control group with conventional endocrinologist follow up (C; n = 50) or the dietitian-coached group (DC; n = 51) with on-site diabetes self-management education every 3 months combined with annual endocrinologist followup. Over the 24 month intervention, weight (-0.7 vs. +2.1 kg; p = 0.04), BMI (+0.3 vs. +0.7 kg/m(2); p = 0.009), and waist circumference (-1.3 vs. +2.4 cm; p = 0.01) significantly differed between the DC and control groups. HbA(1C) dropped significantly in participants of the DC versus the control group (-0.6% vs.-0.3%; p = 0.04). This was accompanied by improved overall energy intake (-548 vs. -74 kcal/day; p = 0.04). However, no link associated glycemic control to nutrient intake or intensiveness of pharmacotherapy. Coaching by a dietitian improves glycemic control and reduces certain cardiovascular risk factors in diabetic subjects, demonstrating that a joint dietitian-endocrinologist model of care provides a convenient strategy for cardiovascular risk management in the diabetic population.
