The purpose of this study was to investigate the effects of a nutrition education and exercise on nutritional status in hemodialysis patients, with regard to quality of life (QoL), and fatigue. The subjects were divided into two groups : an educated (E) group (11 men and 9 women) and a non-educated (NE) group (7 men and 22 women). The educated group received a nutrition education and a regular exercise program for 3 months. Data on anthropometric indices and biochemical parameters were obtained from medical records. Dietary habits and nutrient intake were assessed through questionnaires and three-day food records. QoL (through the SF-36 questionnaire) and fatigue (measured by a visual analogue scale questionnaire) were assessed before and after the interventions. Dietary habit scores regarding food variety and fluid intake control significantly increased (P<0.05) after the nutrition education. Furthermore, the intake of total energy, carbohydrates, Fe, and vitamin A significantly increased (P<0.05). Vitamin C intake also significantly increased (P<0.01). Hb levels decreased whereas TG levels increased in the NE group. BUN levels decreased in the E group. After the nutrition education, QoL aspects, such as feelings of pain and general health, and the total score significantly increased (P<0.05) and the level of fatigue score decreased (P<0.01). The results of this study indicate that nutrition education and exercise for hemodialysis patients provides changes in dietary habit, daily nutrient intake, biochemical parameters, QoL, and the level of fatigue. Therefore, nutrition education and exercise help improve nutritional status and QoL.

The purpose of this study was to investigate the effect of nutritional education on the knowledge and the practice & Perception of diet therapy, and on the level of FBG and HBAlc. The subjects were selected among the patients treated in the Inha University Hospital from June of 1996 until April of 1998. Educated group consisted of 20 patients who visited the diet-counseling department as a part of diabetic treatment. Non-educated group consisted of 20 patients who visited the diet-counseling department ignoring doctors prescription purpose. The knowledge and the practice & perception of diet therapy drinking & smoking habits, regular exercise, and general characteristics including family history were analyzed by questionnaires. FBG and HbAlc were measured before and 4 months after the treatment. The results were as follows : Both groups were composed of 12(60%) male and 8(40%) female respectively. The mean age of subjects was 51.4 years in educated group and 51.9 tears in non-educated group. The duration and %IBW were 5.9 years and 109.8 % in educated group and 5.5 years and 111% non-educated group respectively. There were no significant differences in drinking & smoking habits and regular exercise between groups. The diet therapy knowledge score was significantly higher in educated group(p<0.001, 5.8$\pm$2.3/10.0 vs 3.4$\pm$2.0/10.0). The diet therapy practice & perception score was also significantly higher in educated group(p<0.001, 5.6$\pm$2.3/10.0 vs 2.8$\pm$2.2/10.0). Levels of FBG and HbAlc in both group were reduced at 4 month after the treatment(-74.2 mg/dl and -1.4% in educated group vs -58.7 mg/dl and -2.0% in non-educated group). However, the reduced amounts of them were not significantly different. Therefore, nutritional education seems to be very important in improving the knowledge and the practice & perception of the diet therapy. However, it appears no direct influence in reducing FBG and HbAlc levels. Further studies on diabetic management by using more efficient, consecutive and intensive nutritional education methods are needed. (Korean J Nutrition 34(1):69-78, 2001)

Antioxidants such as vitamin C and E may play a preventive role in the development of cancer and coronary heart disease. The status of vitamins C and E may be affected by lifestyle habits such as smoking , drinking, and exercise. These habits can modify the dietary requirements of vitamin C and vitamin E. the purpose of this study was to determine whether Korean young healthy men and women consume vitamins C and E in sufficient quantities relative to their lifestyle habits. Among the participants in this study, 52% of the men and none of the women were smokers. ; 84% of all subjects drank alcohol more than once a week ; and the men exercised more often than the women. The concentrations of serum total , HDL-, and LDL- cholesterol were higher in the women than in the men, but the serum triglyceride concentrations were higher in the men than in the women. The men consumed less satuated fat than the women (p<0.05) . The daily intakes of vitamin C for the men and the women were 47.1mg and 65.6mg, respectively. On the other hand , the daily vitamin E intake was higher in the men (11.8mg) than women(6.9mg). The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and in no subjects were they below the minimum value of ranges. However, about 19% of male subjects and 10% of female subjects showed deficient status, although the mean serum vitamin C levels were normal . Lifestyle habits fo the sort mentioned above have little influence on the serum vitamin C and $\alpha$-tocopherol concentrations. The serum $\alpha$-tocopherol concentration had a positive correlation with total fat and alcohol consumption. The serum vitamin C concentration was positively associated with regular exercise, but it was negatively correlated with the number of cigarettes smoked. Meanwhile, the serum lipid persoxide concentration , the indirect index of oxidative stress, was influenced by certain variable such as body mass index , the number of cigarettes smoked , alcohol consumption, energy expenditure, vitamin C intake, and serum ${\gamma}$-tocopherol concentration. Serum lipid peroxide concentration was positively associated with body mass index, the number of cigarette smoked , serum triglyceride , and HDL-cholesterol concentration. In conclusion , the vitamin E requirements of the subjects were met by the Recommended Daily Allowance (RDA) regardless of lifestyle habits. However, serum vitamin C concentrations showed individual variation and was below the normal ranges. Smoking and exercise influenced serum vitamin C concentration. Therefore, a reevaluation of the requirements of vitamin C relative to lifestyle habits is necessary.

This study was performed to assess the relationship between diet quality and general characteristics, stress, exercise habits, and nutritional knowledge score in the postmenopausal women. The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. Diet quality was assessed by INQ(index of nutritional quality), MAR(mean adequacy ratio), DDS(dietary diversity score), DVS(dietrary variety score), DQI(diet quality index). The results are summarized as follows. The mean age of the subjects was 59.9 years old. The means of height, weight, and BMI were 154.7cm, 57.2kg and 23.9 respectively. The subjects who did not exercise regularly were 70.9% and those who excercised at least once a week were 29.1%. The subjects who had regular meal time were 69.5% and those who ate breakfast regularly were 72.6%. More than 2/3 of subjects had regular eating behavior. Overall dict quality was significantly(p < 0.05) associated with INQ, MAR, DDS, DQI. However, there was no significant association between income level and diet quality. In conclusion, it would be beneficial to provide nutritional education included dietary diversity, dietary variety, dietary guideline, and adequate flood amount, to prevent chronic degenerative disease and maintain healthful life in the postmenopausal women.

Objective The purpose of this review was to investigate exercise therapy by sasang constitution and to offer information for further research. Method The literature was investigated from KMBASE, KISS, ScienceON, JSCM, DBpia, Pubmed. The searching term were sasang, sasang constituion, sasang type, taeyangin, taeeumin, soyangin, soeumin, exercise, physical therapy, physical activity, and so on. Studies were extracted and analyzed exercise by sasang constitution, in addition, were also collected physiological differences related to sasang constitution, exercise ability, exercise response and effects, and exercise contraindications. Result & Conclusion It is helpful for Taeyangin to lower the energy through exercises that train the lower body and deep breathing, and there is no need to exercise excessively. Taeeumin tend to be obese compared to other constitutions. In order to be physically healthy, it is good to sweat a lot through regular exercise. It is good to do aerobic exercise that burns a lot of calories every day. Soyangin has a weak lower body, so it is good to exercise to reinforce the lower body. Soyangin has weak stamina, and since static exercise easily loses interest, it is helpful to do exciting exercise, and it can be performed at normal intensity. Soeumin are statistically less physically active. So soeumin need to improve exercise habits, but because physical strength is on the weak side, it is more appropriate to do an exercise that activates the body parts evenly rather than a strong one.

The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI) : underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

The principal objective of this study was to assess the effects of eating habits and health-related lifestyle on blood pressure, $\gamma$-Glutamic acid Peptide Transferase ($\gamma$-GPT), glucose and HDL-Cholesterol (HDL-C). All subjects (261 male, 252 female) were from the Iksan area of Korea, and were at least 50 years of age. The mean systolic blood pressure (SBP), diastolic blood pressure (DBP) and HDL-C for all the subjects was 131.3 mmHg, 78.5 mmHg, and 43.1 mg/dl, respectively. The HDL-C of the $50{\sim}64$ year-old group was higher than that of the over-75-year-old group. The "regular breakfast" group evidenced a lower SBP, $\gamma$-GPT, and higher HDL-C than the "seldom breakfast" group (p<0.001, p<0.001, p<0.01). SBP in the "snacking everyday" group was higher than that of the "seldom snacking" group (p<0.001). As for the frequency of using alcohol, SBP and $\gamma$-GPT for the group using alcohol everyday were higher than those of the non-drinking group (p<0.001, p<0.001), SBP and DBP were higher and $\gamma$-GPT was lower in the group that regularly drank more than 4 glasses of Soju than in the non-drinking group (p<0.001, p<0.05, p<0.001). SBP, DBP, and $\gamma$-GPT for the "heavy smoker" group were higher than those of the non-smoker group (p<0.01, p<0.01, p<0.05). The HDL-C was lower in the "heavy smoker" group than in the "non-smoker" group (p<0.05). The SBP with exercise was as follows: Group 1 ($0.022{\sim}0.073\;kcal/min/kg$) was lower than that of Group 3 ($0.144{\sim}0.161\;kcal/min/kg$) and Group 4 (0.161 kcal/min/kg) (p<0.001). To conclude: advancing age, snacking, and frequent alcohol consumption increased blood pressure; the lowest blood pressure was detected in the group that ate breakfast everyday and in the group that engaged in more frequent exercise; Moreover, $\gamma$-GPT was higher and HDL-C was lower in the smokers' group than in the non-smokers' group. Considering the results of this study, there appears to be an urgent need to instruct aging adults about eating breakfast everyday, reducing smoking, using less or no alcohol, and getting proper and regular exercise.

This cross-sectional study was conducted to describe the changes of plasma cardiovascular disease(CVD) risk factors in Korea. Overnight fasting plasma levels of total cholesterol, high density lipoprotein(HDL)-cholesterol, triacylglycerol and glucose were analyzed. Blood pressure and anthropometric data were also measured. Health practice factors such as smoking status, alcohol consumption and frequency fo exercise were evaluated by a self-administered questionnaire. Questions regarding dietary habits and food preferences were also asked. Seventy eight percent of the subjects had more than one CVD risk factor. Plasma total cholesterol, triacylglycerol, and fasting blood glucose were significantly increased according to the subjects body mass index$(kg/m^2$, BMI), whereas HDL-cholesterol, low density lipoprotein(LDL)-cholesterol and blood pressure showed no significant differences with BMI. Current smokers had significantly high plasma total cholesterol, LDL-cholesterol and triacylglycerol levels. Alcohol consumption significantly increased plasma total cholesterol and fasting blood sugar, but regular exercise had no effects on the plasma CVD risk factors. Overeating and frequency of fast food consumption were positively correlated with the CVD risk score, whereas intake of grains, meats and vegetables were negatively correlated with that score. A stepwise multiple regression analysis was performed to examine the effects of specific dietary factors on plasma lipid levels. For plasma total cholesterol level, the frequency of fast food intake explained 8% of the variance, followed by habitual overeating, frequency of grain intake and high cholesterol food intake(Model $R^2$=22.4%). For plasma triacylglycerol level, preference of oily foods accounted for 7.5% of the variance, followed by eating breakfast, preference of fruit and frequency of grain intake(Model $R^2$=22.0%). The findings suggest that intervention programs to reduce the risk of CVD should focus on health practice through reducing BMI, smoking cessation and moderate or no alcohol drinking. Moreover, desirable dietary habits such as eating breakfast, not overeating and reduced intake of fast food may improve CVD risk.

We compared the dietary behaviors and living habits of Han Children living in both China and Korea to find any influences from the different living environments. Three hundred $5^{th}$ and $6^{th}$ -grade children in China and two hundred thirty three $5^{th}$ and $6^{th}$ -grade children in a Chinese school in Korea were surveyed via questionnaire. Mean BMI was higher and sleeping hours were lower in the children living in Korea compared to the children living in China. Mean age and education level of the parents were higher in the children living in Korea. Most of the dietary behaviors discovered via the questionnaire showed similar tendencies in the two groups. However, in terms of skipping breakfast, deviating in food habits, snacking before sleeping, and snacking right after eating a meal, the children living in Korea showed significantly higher frequencies. Also, children living in Korea showed significantly lower frequencies of overeating, snacking while watching TV or using the computer, and eating food when stressed, than children living in China. In living habits, children living in Korea do less regular exercise and use buses or cars more frequently for short distance transportation and spend more time to watch TV or computer than the children living in China. Therefore, it seems that different living environments may somewhat influence the dietary behaviors and living habits of children even if they have the same ethnic background.
