Intervention with delivery of diabetic meals improves glycemic control in patients with type 2 diabetes mellitus

The aim of this study was to investigate the effects of a diabetic meal delivery system on glycemic control over a 12 month period in patients with type 2 diabetes. A total of 77 patients with type 2 diabetes were assigned randomly into three dietary intervention groups: group M, diabetic meal delivery; group D, individual dietary counseling; and group C, conventional dietary education. In group M, HbA(1c) levels decreased significantly from 8.2 +/- 1.2% to 7.4 +/- 0.8% after 12 months (p<0.05), while in group D, HbA(1c) levels decreased significantly throughout the entire 12 month period, from 8.5 +/- 1.7% at baseline to 7.4 +/- 1.1% at the endpoint. Similarly, fasting blood glucose (FBG) levels decreased significantly between 1 and 12 months in group M (p<0.05), and decreased significantly during the entire 12 month period in group D (p<0.01). There were no significant changes in either HbA(1c) or FBG levels in group C. This study provides evidence that intervention with delivery of diabetic meals to patients with type 2 diabetes can be equally effective for achieving glycemic control as individual dietary counselling by a dietitian. Diabetic meal delivery can therefore be used successfully to provide diabetes education to outpatients.
