This study examined the effects of nutrition counseling by the nutrition care process (NCP) on diet therapy practice and glycemic control in patients with type 2 diabetes mellitus.
The survey was conducted on 49 patients whose hemoglobin A1c (HbA1c) level ranged from 6.5% to below 10% among patients aged 30∼60s with type 2 diabetes mellitus. Nutrition counseling by the NCP process was carried out twice: first nutrition counseling and follow up counseling. The questionnaires were composed of 54 questions in five fields (general characteristics, health-related behaviors, diet therapyrelated items, dietary life, diet therapy-related knowledge, diet therapy-related barriers). Nutrition intervention in nutrition counseling was performed based on the individualized diagnosis of NCP.
All the subjects practiced self-monitoring of their blood glucose levels, regular exercise, and diet therapy after NCP-based nutrition counseling. Diet therapy-related knowledge and practice by the subjects were improved after nutrition counseling. While the intake of boiled white rice decreased, the intake of boiled brown rice and barley rice in the subjects increased significantly. After nutrition counseling, the weight and HbA1c of the subjects decreased.
These results suggest that personalized nutrition counseling by NCP process is effective for diet therapy compliance and glycemic control of type 2 diabetic patients.
