BACKGROUND: Diabetes was common problem in older adults. However, there were widespread misconceptions about possible consequences of uncontrolled hyperglycemia. So we studied the frequency of misconceptions and their relationship with knowledge about diabetes. glycemic control, and clinical characteristics of elderly diabetic patients. METHODS: Among 127 medical records of elderly diabetic patients. we investigated age. sex, duration of diabetes. onset age of diabetes, body mass index. We interviewed about history of admission due to diabetes information source of diabetes, level of education, experience of education for diabetes and self care status such as self monitoring of blood glucose and urine glucose. daily foot care and measurement of body weight. For evaluation of misconception and knowledge. we used structured interviews based on validated scales. RESULTS: There was no relationship between frequency of misconception and age, sex, duration of diabetes, information source of diabetes level of education, experience of education for diabetes and self care status such as self monitoring of blood glucose.and urine glucose, daily foot care and measurement of body weight. But the score of knowledge was related with good glycemic control state (Hb Alc < 7.0%) and good self-care status (self monitoring of blood glucose, and measurement of body weight) And linear relationship between the frequency of misconception and score of knowledge was found ( p<0.001) CONCLUSION: Our study suggested that the glycemic control was related with the score of knowledge, but not with frequency of misconception. But further study about other misconceptions will be needed for improving patients quality of life and reducing long-term complication.

The purpose of this study was to investigate the related factors to child overweight through investigation of children aged 6-12. Data on physical examinations, family history and dietary habits were obtained. Children were classified into normal(98 persons) and overweight(118 persons) group using the combination of height for age, weight for age and weight for height standard by the World Health Organization. Children's height, weight and BMI exhibited a significant difference between groups except children aged 8 for height. Unbalanced diet was a risk factors for overweight(Odd ratio : 1.765, 95% CI : 1.022~3.048). Number of brothers showed negative significance especially in two brothers compared to that of one(Odd ratio : 0.456, 95% CI : 0.209~0.995). But Birth weight, feeding practice, overeating, taking nutrition pills, sleeping time, mother's education level and employmental status didn't have any difference. We found out there were different risk factors between obese and overweight group. They should be divided into different groups in studying risk factors. And we should pay much attention to overweight children in order to prevent improving to obesity.

BACKGROUND: The typical Korean diet includes rice, which is usually served in a rice bowl. We investigated the effects of a meal plan using rice bowls of varying sizes on dietary energy intake (EI), body weight (BW), and blood glucose levels. METHODS: Forty-two obese women with type 2 diabetes mellitus were randomly assigned to use either a 200 mL small rice bowl (SB), a 380 mL regular rice bowl (RB), or to a control group (C). Both intervention groups were asked to reduce their EI by 500 kcal/day for 12 weeks and simple instructions for using the assigned bowl were provided. Dietary EI and proportion of macronutrients (PMN) were estimated from 3-day dietary records. RESULTS: Reduction of EI was more prominent in the SB group compared to the RB and C group, although EI decreased significantly from baseline in all groups. Carbohydrate and fat intakes of the SB group were decreased greater than those of the RB and C group. However, changes in PMN were not significant across the 3 groups. Reduction of BW and HbA1c levels in the SB group was more prominent compared to the C group. Although, BW and HbA1c were decreased significantly from baseline in both bowl groups. There was no statistical difference between the two groups. CONCLUSION: The small rice bowl-based meal plan was effective at reducing EI, BW, and blood glucose levels, and the observed reductions in EI, carbohydrate, and fat intake were greater than those of the regular rice bowl-based meal plan.

Purpose: The preemptive use of renin-angiotensin system (RAS) inhibitors may reduce doxorubicin (DOX)-related cardiotoxicity. Using the national insurance claims data of Korea, this study compared cardiovascular (CV) outcomes following the use of four major antihypertensive drug classes in patients with hypertension and breast cancer who underwent DOX-containing chemotherapy. Methods: A total of 4,722 patients with hypertension and breast cancer who underwent DOXcontaining chemotherapy were included. The outcomes were compared between patients who used RAS inhibitors, calcium channel blockers (CCBs), beta-blockers (BBs), and thiazide and thiazide-like diuretics (TDs). The primary outcome was a composite of incident heart failure and serious ventricular arrhythmias, including ventricular tachycardia and fibrillation, ischemic heart disease, and stroke. Results: In the propensity score-matched population, there were no significant differences in the primary outcome between RAS inhibitor and CCB users; however, patients with diabetes who used CCBs had a worse primary outcome than those who used RAS inhibitors (adjusted hazard ratio [aHR], 1.93; 95% confidence interval [CI], 1.06–3.51). BB and TD users had a worse primary outcome compared with RAS inhibitor (aHR, 1.88; 95% CI, 1.30–2.71 in BB users and aHR, 2.55; 95% CI, 1.37–4.75 in TD users) or CCB (aHR, 1.54; 95% CI, 1.09–2.16 in BB users and aHR, 2.08; 95% CI, 1.13–3.82 in TD users) users. Conclusion RAS inhibitors are preferred for the treating hypertension and improving CV outcomes in patients with hypertension and breast cancer undergoing DOX-containing chemotherapy, particularly in patients with comorbid diabetes. However, CCBs are equivalent to RAS inhibitors and are more favorable than BBs and TDs in terms of improving CV outcomes.

BACKGROUND: The regular meal pattern with consistent day-to-day calorie and carbohydrate intake is one of the most important determinants of good glycemic control in diabetes. This study was aimed to investigate the meal pattern and their relationships with total energy intake, nutrients intake and glycemic and lipid profile in type 2 diabetes. METHODS: 1,084 subjects were divided according to glycemic status into three groups: the diabetes (DM), dysglycemia (DG) and normal (N). The meal frequency (MF), meal interval (MI) and daily intake of total energy, macronutrient and micronutrient were estimated with the 24 hours dietary recall from the Korean National Health and Nutrition Examination Survey (KNHANES) in 2001 and Eulji hospital. For analysis of meal pattern and it's relations with the nutrients intake, we regrouped into meal skipper (G1), non-meal skipper with unreasonable MI (G2), and non-meal skipper with reasonable MI (G3). RESULTS: 17.5% of DM, 21.8% of DG, 23.3% of N skipped at least one meal a day without significant difference across the groups. 55.9% of non-meal skipper had unreasonable MI. Meal was more regular in older age, lower educated person, employee, and female. G1 took higher fat, and more calories form snack and less micronutrient density, compared with G3 (P < 0.05). HbA1c, total cholesterol and triglyceride values were higher in G1 compared with other two groups (P < 0.05). CONCLUSION: Many type 2 diabetics had the irregular meal patterns, which was associated with poor glycemic control, lipid profiles and less micronutrient density. This suggested that another treatment strategy might be required for those who had irregular lifestyle.

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.

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.

BACKGROUND: Our goal was to investigate the effects of low intensity resistance training on body fat, muscle mass and strength, cardiovascular fitness, and insulin sensitivity in type 2 diabetes. METHODS: Twenty-eight overweight women with type 2 diabetes were randomly assigned to a resistance training group (RG, n = 13) or a control group (CG, n = 15). RG performed resistance training using elastic bands, of which strength was equal to 40 to 50% of one repetition maximum (1RM), for three days per week. Each exercise consisted of three sets for 60 minutes. We assessed abdominal fat using computed tomography, muscle mass using dual-energy X-ray absorptiometry, and muscle strength using Keiser's chest and leg press. Insulin sensitivity was measured using the insulin tolerance test, and aerobic capacity was expressed as oxygen uptake at the anaerobic threshold (AT-VO2) before and after the 12-week exercise program. RESULTS: The age of participants was 56.4 +/- 7.1 years, duration of diabetes was 5.9 +/- 5.5 years, and BMI was 27.4 +/- 2.5 kg/m2, without significant differences between two groups. During intervention, a greater increase in muscle mass and greater decreases in both total fat mass and abdominal fat were observed in RG compared to those of CG (P = 0.015, P = 0.011, P = 0.010, respectively). Increase in 1RM of upper and lower extremities was observed in the RG (P = 0.004, P = 0.040, respectively), without changes in AT-VO2 and insulin resistance in either group. CONCLUSION: In conclusion, the low intensity resistance training was effective in increasing muscle mass and strength and reducing total fat mass without change of insulin sensitivity in type 2 diabetic patients.

BACKGROUND: The Korean National Health and Nutrition Examination Surveys reported 65% of daily energy intake (EI) as carbohydrate (CHO) in the Korean population and main source of CHO was cooked rice. We used a standardized-small sized rice bowl for diet education and investigated its effectiveness on body weight, glucose and lipid, compared to the conventional food exchange system in type 2 diabetes obese women. METHODS: Type 2 diabetic women with body mass index > or = 23 kg/m2 were randomly assigned to small rice bowl-based meal plan (BM) and food exchange-based meal plan (ExM) group. Both groups were asked to reduce their EI by 500 kcal/day for 12 weeks. The macronutrient composition was instructed: 55 to 60% of EI as CHO, 15 to 20% as protein, and 20 to 25% as fat. BM group received only a simple instruction for application of the rice bowl. Nutrient intake was estimated with the 3-day dietary records. RESULTS: Finally, 44 subjects finished the study. The percent reduction of body weight was significant both BM group (-5.1 +/- 2.6%) and ExM group (-4.8 +/- 2.8%) after 12 weeks (P < 0.001) but there was no difference between the groups. There was no difference in the proportional change of CHO, protein and fat in EI between the groups. Additionally, the change of HbA1c and low density lipoprotein-cholesterol were not significantly different between the two groups. CONCLUSION: The BM group was as effective as ExM for body weight and glucose control in type 2 diabetes obese women.
