BACKGROUND
Weight loss through low-calorie diets (LCDs) decreases visceral fat (VF). However, the effects on muscle mass, changes of dietary quality, and insulin sensitivity are unknown for Korean obese type 2 diabetic subjects. Therefore, this study examined such effects of LCDs. METHODS: A total of 30 obese type 2 diabetic subjects (body mass index, 27.0 +/- 2.2 kg/m2) were randomly assigned to an LCD or control group. Subjects on LCDs took 500~1,000 kcal fewer energy than their usual dietary intake (1,000~1,500 kcal/day) over the course of 12 weeks. The abdominal VF and femoral muscle mass were evaluated by computed tomography, and insulin sensitivity was assessed using an insulin tolerance test (Kitt; rate constant for plasma glucose disappearance, %/min). Dietary nutrient intake consumed by subjects was assessed by 3-day food records. RESULTS: The percent VF reduction was -23.4 +/- 17.2% in the LCD group and -9.8 +/- 11.8% in the control group after 12 weeks (P < 0.001, P = 0.002). However, significant decrease in femoral mass or proportional change of marcronutrient intake and mean adequacy ratio were not found in the LCD group, as compared to the control group. Insulin sensitivity improved in the LCD group, as compared to the control group (P = 0.040). CONCLUSION: LCD effectively improved insulin sensitivity and reduced abdominal VF without reduction of femoral muscle and dietary quality in obese type 2 diabetic subjects.

AbstractAbstract PDF
BACKGROUND
Combination fitness regimens (including aerobic and resistance exercises) are effective for improving cardio-respiratory fitness, reducing visceral fat and increasing insulin sensitivity in diabetic patients. The combination exercise intensity that a patient is capable of is limited by his or her aerobic capacity and one repetition maximum (1RM). We investigated the relationships between 1RM, aerobic exercise capacity and body mass index in patients with type 2 diabetes. METHODS: A total of 177 (men: 85, women: 92) diabetic subjects with HbA1c < or = 10% were enrolled. Muscle strength and 1RM were assessed bychest press (upper body) and leg press (lower body). We assessed aerobic capacity by VO2max and muscle mass by bioimpedance analysis. RESULTS: There was no correlation between 1RM and VO2max in type 2 diabetic patients (upper: P = 0.122, lower: P = 0.138 for men, and upper: P = 0.952, lower: P = 0.570 for women). However, 1RM was significantly correlated with muscle mass both in men and women (upper: r = 0.493, P < 0.001, r = 0.315, P = 0.002 lower: r = 0.437 P < 0.001, r = 0.307, P =0.003, respectively). There was also a significant correlation between 1RM and BMI. In obese male subjects with BMI > or = 25 kg/m2, we observed a significant correlation between muscle mass and BMI (r = 0.374, P = 0.032), but this correlation was not observed in women. CONCLUSION: Clinicians treating Korean type 2 diabetic subjects should recommend resistance exercise to their patients. In particular, obese women with diabetes may receive greater benefits by increasing muscle mass through resistance exercises.

AbstractAbstract PDF
BACKGROUND
It is difficult to improve muscle strength with only aerobic exercise training in type 2 diabetes patients. Resistance training is effective for improving muscle mass, muscle strength and insulin sensitivity. One repetition maxima (1RM), or the maximum amount of weight a subject can lift in a single repetition, may be a useful unit for evaluating the results of resistance training in type 2 diabetic patients. This study was aimed to assess baseline values for 1RM in a sample of Korean type 2 diabetes mellitus patients that are scaled for intensity and load of exercise, and to assess the relationship of 1RM to age. METHODS: A total of 266 (male: 95, female: 171) Korean patients with type 2 diabetes mellitus were included in the study sample. Maximal muscle strength was assessed by measuring 1RM for each subject (KEISER, Fresno, CA, USA). Two different exercises were used to measure 1RM: the chest press for the upper extremities, and the leg press for the lower extremities. RESULTS: Both upper and lower values of 1RM decreased with age in men and women; upper 1RM: r = -0.454, P<0.001 in men, r = -0.480, P< 0.001 in women, lower 1RM: r = -0.569, P<0.001 in men, and r = -0.452, P<0.001 in women. Values of 1RM significantly decreased in men only after the age of 70. In women, values of 1RM continuously decreased after the age of 60. CONCLUSION: The maximal muscle strength of individuals with type 2 diabetes decreases with age. We believe that resistance training is especially beneficial for type 2 diabetes mellitus patients after the sixth decade of life.

AbstractAbstract PDF
BACKGROUND
Exercise offers protection against atherosclerosis and insulin resistance. We evaluated the benefits of exercise at different levels of intensity for ameliorating inflammation, endothelial dysfunction, and insulin resistance in a sample of type 2 diabetic subjects. METHODS: Fifty-nine overweight women with type 2 diabetes were randomly assigned to control (CG, N = 18), moderate-intensity exercise (MEG, N = 17), and vigorous-intensity exercise (VEG, N = 14) groups. Patients in the two experimental groups completed a 12-week exercise program, with their exercise activities monitored by accelerometers. We assessed the patients' body weights, total abdominal fat (TF), subcutaneous fat (SF) and visceral fat (VF) via computed tomography, measurements of plasma levels of hs-C-reactive protein (hs-CRP) and interleukin-6 (IL-6), assessment of endothelial function by brachial artery flow-mediated dilation (FMD), and evaluation of insulin sensitivity by insulin tolerance tests, at baseline, at the end of the 12-week interventions, and one year after initiation of the study. RESULTS: At baseline, the average age of all subjects was 54 +/- 7 years, and average body mass index (BMI) was 26.9 +/- 2.5 kg/m2. During the intervention, patients in the MEG and VEG groups expended comparable amounts of activity-related calories (488.6 +/- 111.9 kcal/day, 518.8 +/- 104.1 kcal/day, respectively). Although BMI, TF, and SF decreased similarly in the MEG and VEG groups (deltaBMI: -1.1 +/- 0.7, -0.8 +/- 0.5, deltaTF: -4,647 +/- 3,613 mm2, -2,577 +/- 2,872 mm2, deltaSF: -2,057 +/- 2,021 mm2, -1,141 +/- 1,825 mm2, respectively), compared to control (P<0.01), hs-CRP, IL-6, and FMD remained constant in both exercise groups even after completion of the 12-week exercise intervention. Insulin sensitivity improved only in patients subjected to vigorous exercise (VEG). Visceral fat loss was observed only in patients subjected to moderate exercise (MEG). At one-year follow up, these values had all returned to baseline. CONCLUSION: Exercise vigorous enough to result in significant weight and fat reduction did not ameliorate inflammation and endothelial dysfunction as measured at the end of a 12-week exercise intervention, nor did it result in sustained improvements in insulin sensitivity in type 2 diabetic subjects.

AbstractAbstract PDF
BACKGROUND
The results of previous studies suggest that portion size is a major factor dictating dietary energy intake. We investigated the relationship between frequencies of rice meals, bowl volumes, and dietary energy intake in a sample of patients with type 2 diabetes. METHODS: A total of 203 type 2 diabetes patients were enrolled in the study. A one-week food diary was collected from each patient and used to assess the types of meal consumed as well as the context of consumption. The volumes of the eating vessels (rice, soup and side dish bowls) used by each patient were obtained by comparisons to measuring cylinders, and dietary energy and macronutrient intake were estimated for each patient by consulting three-day dietary records. RESULTS: The mean age of the 203 subjects (male: 76, female: 127) was 53.9 +/- 9.1 years and the average body mass index (BMI) was 25.6 +/- 4.2 kg/m2. Among the subjects who ate three times per day, 96.4% consumed rice more than twice out of three meals. The median volume of rice bowls used by patients was 350 cc, of soup bowls was 530 cc and of side dish bowls was 260 cc. Portion size, as estimated by rice bowl volume, was not associated with BMI. Male subjects tended to eat out of larger rice and soup bowls (P < 0.001). Portion size was correlated with energy intake from rice (P = 0.021), but not with total energy intake (kcal/kg/day), especially in male subjects. CONCLUSION: Portion size of rice bowl was correlated with energy intake from rice, but not with total energy intake in male subjects with type 2 diabetes. To design effective meal planning methods for patients with type 2 diabetes, further prospective studies are warranted to investigate causative relationships between portion size andmetabolic conditions as well as variation by gender.

BACKGROUND
The relative effect of diabetes on the risk of cardiovascular disease in Asian population is much the same as that in Western populations. Although multiple atherosclerotic risk factors have been documented in Asia, precise estimates of vascular reactivity might provide more critical informations for the prevention and the control of diabetes-related cardiovascular mortality and morbidity. The aims of this study were to estimate the vascular reactivity directly and evaluate its relationship with other cardiovascular risk factors and carotid intimal-media thickness (IMT) in newly-diagnosed Korean type 2 diabetic patients. METHODS: We measured flow-mediated vasodilation (FMD) and endothelial-independent vasodilation (EID) of the brachial artery using high-resolution ultrasonography in total of 121 (M; N = 68, F; N = 53) diabetic patients. We assessed conventional cardiovascular risk factors such as age, smoking, obesity, hypertension, hyperlipidemia or family history of cardiovascular disease and analyzed the association among FMD/EID with cardiovascular risk factors, carotid IMT or the total number of risk factors. RESULTS: The mean values of age, smoking, BMI, waist, systolic blood pressure and diastolic blood pressure were 51.2 +/- 12.3 years, 11.0 +/- 15.8 pack years, 25.0 +/- 3.2 kg/m2, 86 +/- 9 cm, 123 +/- 16 mmHg and 79 +/- 12 mmHg. The mean values of HbA1c, fasting blood glucose, total cholesterol, triglyceride, LDL-cholesterol and HDL-cholesterol were 8.4 +/- 2.0%, 166 +/- 51 mg/dL, 187 +/- 37 mg/dL, 166 +/- 143 mg/dL, 114 +/- 30 mg/dL and 46 +/- 12 mg/dL. FMD and EID were estimated by 6.1 +/- 2.8% and 16.6 +/- 5.6% respectively. The mean/maximal carotid IMT were 0.63 +/- 0.12/0.76 +/- 0.16 mm and the number of risk factors besides diabetes mellitus were 2.3 +/- 1.3. After adjusting age, FMD was associated only with smoking, but EID was associated with smoking, systolic/diastolic blood pressure, mean/maximal carotid IMT and number of risk factors by partial correlations. Age, smoking and EID were independent risk variables for carotid IMT, analyzed by multiple regression test. CONCLUSION: These findings suggest that impaired vascular reactivity detected by EID is closely related to carotid IMT, an useful surrogate marker for atherosclerosis, in newly-diagnosed Korean type 2 diabetic patients.

AbstractAbstract PDF
BACKGROUND
Once daily injection and 24 hour lasting glucose lowering effect of insulin glargine had recently changed a perception about the early insulin treatment of type 2 diabetic patients. This study was performed to investigate therapeutic efficacy of combined therapy with insulin glargine and glimepiride in Korean type 2 diabetic patients, who had received oral hypoglycemic agents (OHA) or conventional insulin therapy. METHODS: Total of 192 patients who needed to change the previous therapy because of uncontrolled diabetes or hypoglycemia were included and followed for about 6 months. Two groups of prior treatment modality were analyzed; OHA group (n = 54, 28.1%), conventional insulin therapy group in combination with or without OHA group (n = 138, 71.9%). The primary end point was changes in HbA1c according to baseline characteristics such as prior treatment modality, HbA1C, c-peptide, duration of diabetes mellitus, body mass index and prior used conventional insulin doses. Secondary end point was the dose conversion ratio of insulin glargine to prior used insulin in patients who had one or two insulin therapy. We also evaluated the level of the patients' satisfaction on the glucose lowering effects and the convenience for use of device. RESULTS: The differences of HbA1c according to prior treatment groups were -0.78 +/- 1.76 % in OHA group and 0.07 +/- 1.44 % in conventional insulin group with or without OHA group. The HbA1c improved better when baseline HbA1c was higher than 9%, c-peptide was higher than 0.6 ng/mL, duration of diabetes was shorter than 15 years, BMI was lower than 30 kg/m2 and prior conventional insulin dose was less than 30 IU. However, those effects were attenuated in subjects having duration of diabetes longer than 16 years, BMI higher than 30 kg/m2 and prior insulin dose more than 40 IU. Dose conversion ratio of the insulin glargine to prior insulin was 0.78 +/- 0.30 and showed a tendency to increase in patients who have prior insulin dose more than 40 IU. The scores of the patients' subjective satisfaction on insulin glargine were all high, irrespective of the changes of HbA1c. CONCLUSIONS: Once daily injection of insulin glargine and oral ingestion of glimepiride can be recommended as one of starting insulin regimen for patients who are not adequately controlled by OHA alone or as once daily regimen for whom treated with one or two conventional insulin therapy.
