The purpose of this study was to evaluate the effect of web-based diabetic education on plasma glucose and serum lipids in obese people with diabetes.

A random allocation design with control and experimental groups being assessed pre- and post-intervention was used. Eighteen patients were randomly allocated to an intervention group and 16 to a control group. Participants were requested to input their blood glucose levels weekly for 3 months at http://www.biodang.com by cellular phone or wire Internet. The researcher sentoptimal recommendations to each patient weekly for 3 months using a short message service (SMS) of the cellular phone and wire Internet.

Patients in the intervention group had a mean decrease of 1.2% in glycosylated haemoglobin (HbA₁c) levels and those in the control group had no difference in HbA₁c levels. There was a significant mean change in 2-hour post prandial blood glucose (2HPPG) for the intervention group, with a mean change of -120.1 mg/dl. The mean change in the control group, however, was not significant.

These findings indicate that this web-based intervention using SMS of the cellular phone for 3 months improved HbA₁c and 2HPPG, but did not affect total cholesterol, triglyceride, and high density lipoprotein cholesterol in obese type 2 diabetic patient.

This study was to evaluate the effects of a short term comprehensive life style modification program on glycemic metabolism, lipid metabolism and body composition in type 2 diabetes mellitus patients.

A nonequivalent control group with a pre post test was designed. Data collection was done from October 2003 to June, 2004 at a hospital. Glycemic metabolism was measured by a.c., p.c. and HbA1c, and lipid metabolism was measured by cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. Body Composition was measured by body weight, body mass index, waist, measurement waist per hip ratio, body fat, muscle weight and abdominal fat tissue(intra abdominal distance). The Experimental group, which was composed of 29 participants, was educated based on a life style modification protocol at a weekly meeting for 12 weeks and carried out exercise, diet along individual parameters and self monitoring, while 24 participants in the control group received only diet education.

1.The experimental group showed a significant lower a.c.(t=2.11, p=.04) and HbA₁c(t=2.65, p=.01) compared to those of the control group. 2. The experimental group showed a significant lower LDL than the results of the control group(t=2.42, p=.02). 3. The experimental group showed a significant lower weight(t=3.09, p=.00), BMI(t=3.01, p=.00), body fat(t=2.94, p=.01) and abdominal fat tissue(t=3.05, p=.01) than those of the control group.

The results provided evidence for the effectiveness of a short term comprehensive life style modification program composed of exercise, diet, support, self efficacy elevation and self monitoring in type 2 diabetes mellitus.

The purpose of this study was to construct and test a structural equation model for Diabetes self-management (DSM) behavior and Quality of life (QoL) in older adults with diabetes who use Citizen Health Promotion Centers. The theory used this study was a combination of the Information-Motivation-Behavioral Model (IMB) and Self-Determination Theory (SDT) to reflect autonomous characteristics of participants.

Data were collected from April 20 to August 31, 2015 using a self-report questionnaire. The sample was 205 patients with type 2 Diabetes who regularly visited a Citizen Health Promotion Center. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factor affecting the participants’ DSM behavior and QoL.

The supported hypotheses were as follows; 1) The variable that had a direct effect on QoL was health behavior adherence (γ=.55, p=.007). 2) The variables that had a direct effect on DSM behavior were DSM information (γ=.15, p=.023), DSM confidence (γ=.25, p<.001), and autonomous motivation (γ=.13, p=.048). 3) The variable that had a direct effect on DSM confidence was autonomy support (γ=.33, p<.001).

The major findings of this study are that supporting patient's autonomous motivation is an influential predictor for adherence to DSM behavior, and integrative intervention strategies which include knowledge, experience and psychosocial support are essential for older adults with diabetes to continue DSM behavior and improve QoL.

The purpose of the study was to identify factors influencing physical activity among community-dwelling older adults with type 2 diabetes. The study design was based on the Theory of Triadic Influence.

A total of 242 older adults with type 2 diabetes participated in this study. Six variables related to physical activity in older adults, including self-efficacy, social normative belief, attitudes, intention, experience, and level of physical activity, were measured using reliable instruments. Data were analyzed using descriptive statistics, Pearson's correlation analyses, and a path analysis.

The mean physical activity score was 104.2, range from zero to 381.21. The path analysis showed that self-efficacy had the greatest total effect on physical activity. Also, experience had direct and total effects on physical activity as well as mediated the paths of social normative beliefs to attitudes and intention to physical activity. These factors accounted for 10% of the total variance, and the fit indices of the model satisfied the criteria of fitness.

The findings of the study reveal the important role of self-efficacy and past experience in physical activity in older adults with type 2 diabetes.

The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey.

Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2.

Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group.

Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.

The study was conducted to develop and test a hypothetical model which explains self-care behavior in patients with type 2 diabetes was established based on the Self-Determination Theory.

The participants were 218 patients with type 2 diabetes mellitus enrolled in an outpatient clinic of one endocrine center in Korea. The data were collected using questionnaires from April 5 through May 7, 2010. The descriptive and correlation statistics were analyzed using the SPSS/WIN 15.0 and the structural equation modeling procedure was performed using the AMOS 7.0 program.

The results of this study showed that competence and autonomous motivation were the strong factors influencing self-care behavior in patients in this sample. Support from health provider for autonomy was a significant indirect factor on self-care behavior. These factors explained 64.9% of variance in the participants' self care behavior. The proposed model was concise and extensive in predicting self-care behavior of the participants.

Findings may provide useful assistance in developing effective nursing interventions for maintaining and promoting self-care behavior in patients with type 2 diabetes.

The purpose of this study was to test the effects of tailored diabetic education on blood glucose control and self-care for patients with type 2 diabetes on insulin therapy.

The participants were 60 patients (experimental group: 30, control group: 30) with type 2 diabetes on insulin therapy. The patients were being seen at a university hospital in Seoul, Korea. Group diabetic education and tailored diabetic education were given to the experiment group while group diabetic education only was given to the control group. Data were collected before and three months after the education. χ² test, t-test, and ANCOVA were used to analyze the data.

No significant differences in postprandial (PP2hrs) glucose and HbA1c levels were found between the two groups. Participants in the experiment group showed statistically significant differences in the area of self-glucose test, management of insulin injection, and life style change compared to those in the control group.

The results indicate that tailored education for patients with diabetes on insulin therapy improve self-glucose test, management of insulin injection, and life style. Therefore it is suggested that tailored education can be applied in diabetic education to improve self-care.

This study was to evaluate the effects of a comprehensive life style modification program on glycemic control and stress response in type 2 diabetes.

The participants(n=34) with type 2 diabetes were divided into either a usual care(control) or treatment(experimental) group. The experimental group(n=21) received a program that was based on a comprehensive life style modification protocol at a weekly meeting for 16 weeks. They also participated in individually prescribed exercise and diet along with stress management and self monitoring. The participants were followed for 6 months, during which postprandial glucose, HbA_1C, and stress response inventory were measured.

The experimental group showed a significant lower postprandial glucose and stress response compared to those of the control group. However, there was no significant change in the HbA_1C value in either group.

These results suggest that a type 2 diabetes comprehensive lifestyle modification program may lead to clinical improvement in glycemic control and reduce the stress response.
