The purpose of this study was to examine the effect of social support on compliance to dietary regimen in noninsulin-dependent diabetes mellitus. Two hundred eighty six adult non-insulin dependent diabetics from Seoul, Kyonggido, Kyongsangbukdo participated in the study. Researchers, dieticians, graduate students majoring in nutrition interviewed patients with a pre-structured questionnaire during June in 1998. The questionnaire included items about demographic factors, general characteristics about diabetes. social support, and compliance to dietary regimen. Descriptive statistics, t-test, ANOVA and Pearson's Correlation were used to analyze the data. The mean scores of support from family was 27.0(0∼44). support from relatives, friends, and colleagues was 14.7(0∼32). Mean score of intangible support from family was 19.9(0∼32) and 12.0(0∼24) from relatives, friends, and colleagues. Mean score of tangible support from family was 7.1 (0∼12) and 2.6(0∼8) from relatives, friends, and colleagues. The mean scores for compliance to dietary regimen was 31.6(0∼42). Regardless of type and source, there was significant(p<0.01) correlation between social support and dietary compliance. Therefore, inclusion of family members in nutrition education for diabetics is essential. It is necessary to find ways to increase social support from relatives, friends, and colleagues.

The purpose of this study was to identify dietary factors related to the incidence of diabetes mellitus in Korea. The study consisted of 165 diabetic patients, male and female, aged 30 to 70 years and 198 healthy persons as controls. Diabetic patients who had been diagnosed with diabetes mellitus for less than five years before the study period were recruited from eight different hospitals located in Seoul, Korea. Socioeconomic status, state of illness, physical activity, food habits and food intake were assessed. Food intake was assessed by food frequency questionnaire method using a 105-food frequency questionnaire developed for diabetic patients. The stress and activity indices of diabetic patients were not significantly different from control, but alcohol consumption and smoking levels were higher in diabetics than controls. Other diseases of male diabetic patients included liver diseases, digestive system diseases, and hypertension, while those of female diabetics were hypertension, neuralgia, arthritis and digestive system diseases. These disease patterns are different from Western countries whose most common complications are hypertension and hyperlipidemia. More irregular and less varied meals were found in the diabetic group compared to the control group, suggesting that diabetic patients have generally undesirable food habits. Otherwise, food and nutrient intake of diabetics did not differ greatly from the control group. It was found that diabetic patients consumed more cereals and less fruit than the control group, and also that male diabetics consumed more alcohol. The carbohydrate : protein : fat energy distribution ratio was 61.7 : 15.8 : 22.5 in male patients and 65.1 : 14.9 : 19.7 in female patients. Discriminant analysis showed that diabetes risk factors differed with sex. In male patients, the important factors were body mass index(BMI), vitamin C intake, family diabetic history and vegetable intake, while in female patients they were BMI, cereals intake, carbohydrate intake, vitamin C intake, stress, food habits and Ca intake. These results show that excessive intake of energy and fat are not the major causal factors in Korean NIDDM. Therefore, the diabetes risk factors of Western countries may not directly apply to Koreans. Mors study is needed to clarify the risk factors of Korean NIDDM.

Metfotrmin is a biguanide antihyperglycemic agent often used for the treatment of non-insulin dependent diabetics(NIDDM). Metformin lowers both fasting and postprandial plasma glucose concentrations by improving insulin sensitivity at hepatic and peripheral tissues. The pharmacokinetics and pharmacodynamics of metformin were studied in Korean healthy volunteers at fasting state over 10 hours. (omitted)

The purpose of the study was to find the sociopsychological factors predicting the intention of compliance with the dietary regimen in diabetes with a questionnaire. Data were collected from 282 adult noninsulin-dependent diabetics in Seoul, Kyoggida, and Kyongsangbukdo in Korea. Stepwise multiple regression analysis was conducted with predictor variables from theories of the Health Belief Model, Social Cognitive Model, The Theory of Reasoned Action , and Social Support. The behavioral intention of compliance with the prescribed diet was the independent variable. Subjects norm self-efficacy knowledge about diet therapy, outcome expectation, relationship with medical team, threat of deterioration of disease, and social support were the independent variables, The mean score of behavior intention was high ie 35.3 out to 42. Subjective norm and self-efficacy were the significant variables to predict the intention of dietary compliance. These variables comprised 39% of the common variance. To increase dietary compliance by influence of the referents and improve self-efficacy significant referents must be included and concrete and practical methods to follow the dietary regimen must be provided in nutrition education.

To determine factors affecting self-care behavior of diabetics, the relationships of hardiness, family support, demographic and medical variables to self-care behavior were investigated in 180 samples with non-insulin dependent diabetes mellitus. In stepwise multiple regression analysis, 26.76% of the variance in self-care behavior was accounted for by family support(15.52%), age(7.76%), and clinical history (2.07%). To compare the magnitude of predictor's significance by gender, stepwise multiple regression was conducted seperatively by gender group. In the male sample 25.22% of the variance in self-care behavior was accounted for by family support, age, and challenge. In the female sample family support, age, and committment were significant predictors in self-care behavior with 28.82% of the variance. The results highlight the value of family support in self-care behavior in diabetics regardless of gender difference. According to the finding of this study, family support is the most significant predictor of self-care behavior in NIDDM. This implicates that in future diabetic care, a family member should be encouraged to participate in the patient education process. Also as hardiness is not supported by a unidimensional construct, more empirical studies are recommended to differentiate the conceptual traits for the three subconcepts of hardiness.

This study was an attempt to investigate various factions, such as the calorie, nutrient intake, physical activity, blood lipids, obesity prevalence and body fat distribution on NIDDM male diabetics. General characteristics, physical activity and exercise levels of subjects were invesigated by interviewing, daily calorie and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participats : weight, height. Also waist and hip circumference were measured on 174 male diabetics to get waist-to-hip circumference ratio as index of the body fat distribution. For measurement of plasma lipids, 12-hour fasting blood samples were drawn The results of this study were summarized as follows : 1. At the onset of diabetes, the major self-diagnosed symptoms were polydipsia, fatigue, and body weight redution 2. The average of daily energy intake of male diabetics was 2106 Kcal which is 96% of the RDA Percentage of energy is that carbohydrate:protein : pat=70:14:16. 3. Among the NIDDM male subjects, 59% was exercise regularly. 4. Obese subjects above in the ideal body weight of 120% are presently 17%, but 39% of subjects were reported to be obese in the past. The mean BMI of the male NIDDM diabetics is 23.3${\pm}$2.6 and the past mean BMI was 25.2${\pm}$2.7 The mean WHR was 0.93${\pm}$0.10. 5. When diabetics were divided into obese and nonobese group according to RBW, energy intake, blood pressure, blood glucose and total cholesterol were not significantly different between the two groups, but LDL and VLDL-cholesterol were significantly higher in the obese group. 6. RBW did not correlate with cholesterol and triglyceride, but WHR correlated significantly with cholesterol and triglyceride. In conclusion, these results from a present study support previous findings indicating that not only the degree of obesity but also the localization of fat is a risk factor for diabetes.

The present study was conducted to evaluate the dietary fiber intake of 130 subjects, that included 49 subjects(29 form Wonju, 20 from Kangnung) with diabetes mellitus, 23 hyperlipidemia patients, and 58 normal subjects. After the type and amount of foods that a subject took for one day were investigated using the 24-h recall method, the intake of various nutrients and dietary fiber were calculated using a program that already contained the information on dietary fiber contents. The results showed that diabetics from Kangnung who did not undergo dietary therapy had more fat intake that those from Wonju, hyperlipidemia patients, and normal subjects thus, had more energy intake. Also, the crude fiber intake in male and female diabetics from Kangnung were 8.43${\pm}$3.47g and 3.35${\pm}$3.29g, respectively, showing significantly high amounts compared to those of male and female diabetics from Wonju, hyperlipidemia patients, and normal subjects; however, the intake of crude fiber per 1,000 kcal in males and females was not significantly different among the four groups. Also, the dietary fiber intake(14.8-19.8g/day) and the dietary fiber intake per energy unit(7.7-10.9g/1,000kcal) were not significantly different between the four groups. The dietary fiber intakes of diabetics and hyperlipidemia patients were not significantly different from those in normal subjects, and these amounts were significantly lower than recommended levels. Thus, the methods of increasing dietary fiber intake, such as developing low-calorie, high-dietary fiber foods or additives, needs to be researched.

As people's income and intake of animal fat rapidly increase, so does choresterol concentration in blood. Thus diseases such as non-insulin-dependent diabetes mellitus(NIDDM)myocardial infraction, high blood pressure, cerebral stroke resulting from atherosclerosis rapidly increase recently. It is very difficult to diagnose atherosclerosis early since its progress is so slow and there is no sypmtoms in the beginning of the disease. In this study a mechanical characteristic, compliance, of the lower leg arteries was measured noninvasively. Changes of blood volume and pressure were measured using impedance plethysmgraphy and mercury sphygmomanometer, respectively. The compliance was calculated by dividing the change of blood volume by the change of pulse pressure ( systolic-diastolic pressure ) . Subjects were 24 asymptomatic persons ranging (rom 30 Ic 58yeras and 14 diabetics from 41 to 59years. The compliances, mean, and systolic pressures were statistically analyzed using a t-test be- tween the healthy and diabetic groups. The average compliance of the healthy and diabetic group was measured 2.79 and 1.82U1/mmHg/cm, respectively and these were significantly different(p<0.01). It was also found that the compliance is a better parameter in differentiating the vascular disease than mean or systolic blood pressure.

This study estimated the re!ation between psychological stress and stress hormones, nu­t tritional status of patients with non-insulin dependent diabetes mellitus(NIDDM). Psycho­l logical stress such as depr'ession and anxiety in 34 diabetics was analyzedin relation to nutrient intake, blood components such as fasting blood sugar(FBS), hemoglobin AIC, stress hormones a and amino acids. The IeveIs of depression and anxiety were measured by The center for ep­i idemiological studies-depc$pm$111.49pg/ml for total catecholamine ( (norepmephrine and epinephrine) and 233.95 $pm$73.99pg/ml for norepinephrine, 94.03$pm$75. 9 97pg/ml for epinephrine, 13.lS$pm$5.55pl/dl for cortisol and 171.50$pm$62.50pg/ml for gul c cagon respectlveIy. The leveIs of stress hormones in diabetics such as total catecholamine, norep­i mephrine cortisol and glucagon were significantly higher than those in normal control. The lev­el of epmephrine was higher in diabetics but the diffierenee was not significant. The calorie m t take in diabetics was 1762$pm$292keal which is S1.4% lower than Korean recommended dietary a allowances(RDA). Calcium intake was slightly low but other nutrients intakeswere higher than R RDA. The value of fasting blood sugar(FBS), usual fasting blood sugar(usual FBS) which refteet a average FBS during 3 months and hemoglobin Al C in diabetics was 1S4.1S$pm$74.22mg/dl, 177.76$pm$42.77mg/dl and S.S4$pm$2.S2% respec디VeIy. The distribution of plasma amino acids in d diabetics was generally in the normal range. The leveI of anxiety in diabetics was positively cor­related with norepinephrine, concentration and usual FBS. The levels of glucagon, usual FBS a and hemoglobin Aj C were pOSI디veIy correlated with the branched chaimamino acid(BCM : leucme, isoleucme and valine)

High dietary fiber(DF) diets lower blood glucose and insulin requirements in diabetics. In this study we evaluated the effects of high dietary fiber(DF) food supplements on glucose metabolism in thirty-four subjects with non-insulin-dependent diabetes mellitus(NIDDM). The subjects were divided into three test groups. Each group's prescribed hospital diets were augmented by one of the three following DF supplements for two weeks: Soybean biscuits containing 5g of total DF-the control group(n=15); Biji biscuits containing 20g of total DF-the high insoluble DF group(n=9); and sea tangle biscuits containing 25g of total DF-the high soluble DF group(n=10). The mean daily DF intake of the subjects during the period were: $19.1\pm4.3g$ for the soybean control group; $32.5\pm4.1g$ for the Bijl group; and $38.1\pm5.5g$ for the sea tangle group. The supplementation of the Biji or sea tangle biscuits singnificantly lowered fasting serum glucose levels(p < 0.05) and resulted in the improvement of glucose tolerance. However, the secretions of insulin, C-peptide, and glucagon and Hb $A_{lc}$ concentration were not affected by the high fiber supplementary feeding for two weeks. The urinary excretion of glucose decreased remarkably after the addition of the DF supplements in all three groups(p<0.05). The results indicate that the supplementation of Biji or sea tangle bascuits possesses a beneficial effect on the improvement of glucose metabolism in subjects with NIDDM.
