Purpose: The purpose of this study was to investigate the knowledge and learning needs on coronary artery disease in diabetic patients by glycemic control. Methods: The subjects consisted of 188 patients at the hospital who had diabetes mellitus. Data was obtained using a knowledge and learning needs questionnaire from January to April 2006. Results: Treatment method, the levels of fasting blood glucose(FBG), and 2-hour postprandial blood glucose(PP2hr) showed meaningful differences between normo-glycemic group(HbA1c < 7%) and hyper-glycemic group($HbA1c{\geq}7%$). The levels of knowledge on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. Etiology and prevention of coronary artery disease were significantly higher in normo-glycemic group than in hyper-glycemic group. The levels of learning needs on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. The learning needs on items of diet control were higher in normo-glycemic group than in hyper-glycemic group. Conclusion: On the base of these results, we should focus on the coronary artery disease education for hyper-glycemic group. Also individual coronary artery disease educational program should be developed for the patients with different level of knowledge and learning needs.

Purpose: The purpose of this study was to review behavior change theories in terms of important variables, concept definitions, and applicability to diabetes self-management behavior. Methods: Six behavior change theories (the Transtheoretical Model, the Health Belief Model, the Theory of Reasoned Action, the Theory of Planned Behavior, Social cognitive theory, and Information-Motivation-Behavioral skills Model) were reviewed which were applied in diabetes self-management interventions. Results: The five key concepts from the five non-stage behavior change theories were delineated. Based on the key concepts, a theoretical framework was formulated as the explanatory model of diabetes self-management behaviors. The four major concepts in Information-Motivation- Behavioral skills Model were included. The cognitive arm of the proposed theoretical framework included constructs related to diabetes knowledge, motivation (beliefs, attitude, social norm), self-efficacy, and intention. Conclusion: The theoretical framework described here includes the key factors of successful diabetes self- management intervention. However, the concept of motivation needs further exploration and clarification for operationalization.

In order to determine the effect of individual patient teaching through home visiting on compliance with sick role behavior and the blood sugar level in diabetic patients, to determine if the effectiveness of the education was still present four year later and to inquire as to the effective time for a repeat education program this study was done through two quasi-experimental researches. The subjects consisted of 52 diabetic patients. The results of the study may be summarized as follows ; 1. Hypothesis I, in which the compliance with sick role behavior, the knowledge on diabetes and the health belief of the experimental group who received a diabetic education program will be higher than those of the control group who didn't receive the diabetic education, was supported by both studies in 1984 and 1988, confirming the effect on diabetic patients of the individualized education through home visiting ; In the 1984 study : Compliance(t＝-11.7, p＜.001) Knowledge(t＝-5.41, p＜.001) Health belief(t＝-4.74, p＜.001) In the 1988 study : Compliance(t＝-4.85, p＜.001) Knowledge(t＝-2.85, p＜.01) Health Belief(t＝-2.99, p＜.005) 2. The Hypothesis II, the blood sugar level of the experimental group will be lower than that of the control, was rejected in both studies, 1984 and 1988. 3. The Hypothesis III, the compliance, knowledge and health belief of the expermental group who received the education program in 1984 will not last till 1988, was supported in part, in compliance and health belief, but not in knowledge. In conclusion those who received the education program twice with an interval of 2 weeks, 4 years ago still had knowledge of diabetes but compliance and health belief had disappeared.

Coronavirus disease 2019 (COVID-19), a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now at pandemic levels leading to considerable morbidity and mortality throughout the globe. Patients with obesity, diabetes, and metabolic syndrome (MetS) are mainly susceptible and more probably to get severe side effects when affected by this virus. The pathophysiologic mechanisms for these notions have not been completely known. The pro-inflammatory milieu observed in patients with metabolic disruption could lead to COVID-19-mediated host immune dysregulation, such as immune dysfunction, severe inflammation, microvascular dysfunction, and thrombosis. The present review expresses the current knowledge regarding the influence of obesity, diabetes mellitus, and MetS on COVID-19 infection and severity, and their pathophysiological mechanisms.

This study was intended to assess the effects of low glycemic index (LGI) nutrition education on dietary management and glycemic control of patients with type 2 diabetes mellitus. The subjects were 48 sex-matched patients with type 2 diabetes mellitus, aged $66.5\;{\pm}\;6.2$ years, visiting a public health center. They were divided into two groups: the control group (males 10, females 14) and the educated group (males 10, females 14). The educated group was provided with a LGI nutrition education program for 7 weeks. The control group was educated only one time for general diabetic education. Anthropometric indices, knowledge and perception of efficacy of low glycemic index carbohydrates, dietary glycemic index (DGI) and glycemic load (DGL), fasting blood glucose, and HbA1c were assessed. In the educated group body weight, body mass index and systolic blood pressure (from $138.0\;{\pm}\;18.9\;mmHg$ to $130.6\;{\pm}\;15.0\;mmHg$) were significantly reduced after the nutrition education (p < 0.05). The scores of knowledge and perception of efficacy of low glycemic index carbohydrates increased significantly in the educated group. Dietary glycemic index and glycemic load of the educated group decreased significantly from $103.4\;{\pm}\;67.6$ to $45.4\;{\pm}\;27.1$ (p < 0.001), and from $173.3\;{\pm}\;135.9$ to $66.8\;{\pm}\;50.4$ (p < 0.001), respectively. Also fasting blood glucose and HbA1c levels of the educated group significantly decreased from $124.5\;{\pm}\;28.8\;mg/dL$ to $96.7\;{\pm}\;21.6\;mg/dL$ (p < 0.001) and from $7.1\;{\pm}\;1.3%$ to $6.4\;{\pm}\;1.2%$ (p < 0.05), respectively. The score of knowledge and perception of efficacy of low glycemic index significantly correlated with fasting blood glucose and HbA1c levels negatively. DGI, DGL and duration of diabetes significantly correlated with HbA1c level positively. From stepwise multiple linear regression analysis, DGI, DGL and the duration of diabetes were extracted as factors influencing HbA1c level of the subjects. The results of this study suggest that low glycemic index nutrition education programs is an effective intervention measure for the glycemic control in type 2 diabetic patients.

The purpose of this study was to develop the customized diet education game (Roly-Poly 160) for type II diabetes and to test its effectiveness. The diet education game for type II diabetic is composed of three kinds of modules as Meal self-management, Card Game, and Quiz Game. Meal self-management was developed to manage the dietary information of each day and to observe changes in the 12-month period. Card game is to find a changed card based on the recommended meal menu during a limited time and Quiz game is to learn knowledge while solving the quizzes about diet. Data was collected from September 28th to October 28th, 2016 at C hospital and G hospital in G district, and 5 times for 1 hour for every 30 people with type II diabetes who applied for diabetic diet education. Knowledge of diabetes and 2 hour postprandial blood glucose were measured repeatedly before and after the experiment. After the Roly-Poly 160 experiment, the knowledge of type II diabetes was statistically significantly increased (p = 0.04), and the fasting blood glucose and the 2 hour postprandial blood glucose decreased statistically decreased (p <.05) and Roly-Poly 160 game clinical efficacy was verified.

Background: We first launched the case management program for diabetic patients who were registered in NHIC (National Health Insurance Corporation) in Korea and conducted this study to assess the effectiveness of the program. Methods: During the period from October in 2002 to March in 2003, 30 case managers performed the program for 71 diabetic patients. We evaluated the effectiveness of the program based on the results of fasting blood sugar level, two hour post-prandial blood sugar level, knowledge for diabetes, difficulty index in diabetes management, and the health risk factor changes of them. We analyzed results related to these factors through $x^2$ test and paired t-test. Results: The ave rage age of the subjects was 58.9. and the numbers of women and men were 43 and 28 respectively. The fasting blood sugar level and two hour post-prandial blood sugar level decreased from 164.3mg/dl to 146.5mg/dl and from 224.0mg/dl to 203.0mg/dl respectively. The knowledge for diabetes and difficulty index in diabetes management changed from 8.13 to 9.10 and from 3.52 to 2.91 respectively, and these changes were the positive. We observed improvement in self-test of sugar level, foot management, oral hygiene and proper medication but not in self-test of nutritional management. Conclusions: This study revealed that the case management program for diabetic patients who were registered in NHIC is significantly effective. However, the program need to study further to understand its long-term effects.

The purpose of this study was to investigate the dietary behavior of people with type 2 diabetes mellitus and to improve their quality of life through medical nutrition therapy. The subjects were 38 persons with type 2 diabetes mellitus visiting a public health center to participate in a dietary education program from Jun, 2003 to Nov. 2003 in Daegu, Korea. The interviews were tape-recorded and analyzed attitude, knowledge, and awareness of patients by focus group interview. Most of the patients were mainly dependent on drug therapy and had little experience of diet education. Barriers to dietary practice adherences were limitations in food selection, lack of will and feel of burden. Barriers to follow guidelines were lack of self-control, confliction with food habits of their family, accessibility, economical problems, fear for the change after dietary practice, food difficulties in meal distribution and difficulties for eating out. After 4 weeks of intensive nutrition education, fasting blood sugar levels were decreased and postprandial and waist circumference were significantly decreased in all patients and 26.9% of patients were under decreased oral hypoglycemic agent dosage due to improved blood sugar level. dietary knowledge of subjects were greatly improved in such items as dietary intake, saturated fat, HbA1C, ideal body weight, and waist circumference.

Purpose: The purpose of this study was to define the concept for psychological insulin resistance in the Korean population with diabetes. Methods: The Hybrid model was used to perform the concept analysis of psychological insulin resistance. Results from both the theoretical review with 26 studies and a field study including 19 participants with diabetes were included in final process. Results: The preceding factors of psychological insulin resistance were uncontrolled blood glucose and change in daily life. The concept of psychological insulin resistance was found to have three categories with 8 attributes such as emotional factors (negative feeling), cognitive factors (low awareness and knowledge, low confidence for self-injection) and supportive factors (economic burden, dependency life, embarrassing, feeling about supporters, feeling of trust in, vs mistrust of health care providers). The 8 attributes included 30 indicators. Conclusion: The psychological insulin resistance of population with diabetes in Korea was defined as a complex phenomenon associated with insulin therapy that can be affected by emotional factors, cognitive factors, and supportive relational factors. Based on the results, a tool for measuring psychological insulin resistance of Koreans with diabetes and effective programs for enhancing insulin adherence should be developed in future studies.

Purpose: This paper studies the influence of the case-management program on the change of blood sugar, lifestyle, and knowledge level of diabetes mellitus (DM) for medium-sized-enterprise employees suffering from DM. Method: Subjects, divided into experimental and control groups, are 59 workers with FBS higher than 126mg/$d{\ell}$ or under DM medication treatment in the medium-sized enterprises, being managed by two distinct university hospital group occupational health management service teams. The case management program for DM patients consists of 6 different processes in which each subject is treated. Result: FBS decreased in the experimental group after the program, while that of the control group increased significantly. In the experimental group, the amount of smoking, the frequency of drinking and the amount of drinking per week decreased. Also, the knowledge level for DM and the change of nutrition management showed significant increase. In the control group, the amount of smoking increased and the frequency of drinking, the amount of drinking and nutrition level did not change significantly. And the knowledge level for DM decreased. Conclusion: We expect that taking this case management program for DM management may significantly improve diabetic patients' overall health.
