This study compared the nutrient intake of obese versus non-obese non-insulin dependent diabetes mellitus (NIDDM)patients for Diabetes Medical Nutrition Therapy. The study was conducted at medical hospitals in Gyeonggi and Seoul fromApril 2009 to November 2009. Fifty-six adult male NIDDM patients were enrolled and divided into two groups: 36 into anobese group (BMI ≥25) and 20 into a non-obese group (BMI<25). To conduct this study, anthropometric measurements,and daily nutrient intake of obese and non-obese NIDDM patients were measured. Daily nutrient intake was estimated by24hr-recall and analyzed by the CAN program. In the results, anthropometric measurements of the two groups showedsignificant differences in weight and BMI (p<0.001). Daily nutrient intake of the two groups showed no significantdifferences, except for vitamin E intake (p<0.05). The total energy intake of the non-obese and obese groups were2,669.9±964 kcal and 2,555.4±803 kcal, respectively, which were both above 113% of the recommended DietaryReference Intakes for Korean (KDRIs). Cholesterol and sodium intake were 378.1±215.6 mg and 6,478.9±2755.1 mg,respectively for the non-obese group. Cholesterol and sodium intake were 308.1±155.6 mg and 6,306.8±2788.9 mg,respectively, for the obese group. Both groups were above 150% of the recommended levels set by the Korean DiabetesAssociation (KDA). However, their antioxidant nutrient intake was appropriate. Meanwhile, their fiber intake was 10.7±5.1g and 9.8±5.2 g, respectively, which was lower than 40% of the recommended intake set by the KDA. The results show thatthe nutritional education for obese and non-obese NIDDM male patients must aim to reduce total energy, cholesterol, andsodium intake, while increasing fiber intake. In addition, the factors related to a patient’s glycosylated hemoglobin, serumlipids, blood pressure, and weight change must be calibrated for the appropriate energy, fat, cholesterol, sodium, and dietaryfiber intake.
