PAI-1 (plasminogen activator inhibitor-1), leptin, and resistin are synthesized and secreted by Int cells of rodents and have recently been postulated to be an important link to obesity. This study was conducted to identify the nutritional regulation of PAI-1, leptin, and resistin gene expression in 0b/ob mice. The mice were divided into four groups according to nutritional status: control, 48 hour fasting, 48 hour-fasting/12 hour-refeeding, and 48 hour-fasting/24 hour-refeeding. The mRNA levels of each peptide were measured by semi-quantitative RT-PCR. In visceral fat tissue, the level of PAI-1 mRNA increased markedly when 48h-fasted animals were refed with a high carbohydrate-low fat diet. However, lasting/refeeding did not appreciably change PAI-1 mRNA levels in subcutaneous fat tissue. Similar results were obtained for resistin mRNA levels in both types of fat tissues. These findings suggest that visceral adipose tissue might be more sensitively involved in the nutritional regulation of PAI-1 and resistin gene expression compared to subcutaneous fat tissue. The level of leptin mRNA decreased markedly in the 48h-fasted animals, and increased markedly when 48h-fasted animals were refed with a high carbohydrate-low fat diet. The nutritional regulation of leptin mRNA showed similar patterns in both types of fat tissues. In conclusion, the nutritional regulation of gene expression encoding PAI-1, resistin, and leptin from adipocytes may vary according to the type of adipose tissue.

Background and purpose : Stroke is a leading cause of death in Korea. Early measures to prevent stroke are extremely important since it has no cure. Korean might have different risk factors since their dietary habits and socio-economical status differ from most western countries. However, the risk factors for stroke in Korea have not yet been identified. Moreover, the lifestyle of healthy Korean adults has not been investigated. In this study we investigate the lifestyle of healthy adults living in Seoul and rural areas and compare the lifestyles of the two. Methods : One hundred seventy one subjects were studied. Among the subjects studied, 128 were from Seoul, the other 43 were from the country area. The age of the subjects was limited to over 40 years. Blood pressure, fast blood sugar, and cholesterol were measured. The subjects' height, weight, body mass index, total body fat, skinfolds thickness of triceps, subscapular and abdomen were measured to determine obesity. Using a structured interview, we assessed : sodium intake, physical activity and exercise, consumption of vegetables, fat, fish and fruits. The results of the two groups were compared. Results : There were no statistical differences in age and education between the two groups of subjects. The mean age of the subjects were 66 years old. The subjects residing in rural areas had a higher intake of sodium(p<0.05), lower physical activity(P<0.05), and higher BMI and body fat (p<0.05) as compared to the subjects in Seoul. Subjects with hypertension were between 24% and 33% and the prevalence of hypertension was the highest when compared to the prevalence of DM or hypercholesterolemia. However, the prevalence of hypertension, DM, hypercholesterolemia, were not significantly different in these areas. Conclusion : Our results show that subjects living in rural areas eat more salty food, exercise less, and tend to be obese. The finding of this study lead to speculation that Korean living in rural areas have less information about the effects of diet on health than city dwellers do. General health and nutrition education programs aimed at the prevention of stroke and other such conditions for rural area Koreans may close the risk factor gap between rural and urban dwellers.

Background/Aims: Dong-Moo Lee Jae-Ma(1837-1900) confirmed the sasangchaejil theory based on the sasang-medicine. This theory has been the main-stem of oriental medicine during 100 years in Korea. But rarely anyone has tried to prove this theory systemicaly. So we have a trial to clarify any relationship between the sasangchaejil and the laboratory and clinical results of mass screening tests. Methods: We evaluated the laboratory values of 280 people who had taken many clinical and laboratory tests. The laboratory examinations were complete blood count, liver and kidney function test, ultrasonogram of the abdomen and breasts, gastrofiberscope, many tumor markers body mass index, blood pressure, glucose, and electrocardiogram, etc. Results: 1) Among the 280 subjects, 187/66.8% were sowumin, 58/20.7% were taewumin and 35/12.5% were soyangin. 2) Those who reacted positive to HBsAb were 22 subjects(62.8%) in soyangin, 57.2% in sowumin and 55.1% in raewumin. But there were no significant correlations. 3) 45 subjects(72.4%) in taewumin had obesity, fatty liver and hyperlipidemia.(P<0.05) 4) 20.6% in taewumin had abnormal LFT suggesting hepatic disease. It was statistically sigificant.(P<0.05) 5) An anemic state was present in women of soyangin and sowumin mostly. Since an iron deficiency anemia is common in women, there were no significant corelations among sasangchaejil. Also urinary tract infectons were common in women. 6) 6 subjects in taewumin(10.3%) had cardiac problems, while only one case(2.8%) occured in soyangin and 7 cases(3.7%) in sowumin. Taewumin was significantly high.(P<0.05) 7) In the case of gastric disease, there was no distinguishable difference among sasangchaejil.(taewumin 37.9%, soyangin 31.4% and sowumin 35.2% rrespectively) 8) There was no significant difference beteen subjects with different blood types using sasangchaejil. Conclusions: There were some significant relationship between sasangchaejil and diseases prevalent to them by the theory of sasang-medicine. But Lee didn't considered the differences of gender, the change of body status according to the development of culture, and circumstances of their lives. Also he didn't consider the existence of infectious agents. Now more systemic study with larger populations are requied.

Objectives : Prevalence of night eating habit associated with substance use and obesity is increasing rapidly in children and adolescents. Further, staying up late and eating snacks late at night were known as leading health risk behaviors for children, suggesting the potential adverse effect of night-eating habit on children. However, only few reports had been issued on the effect of night-eating habit on gastrointestinal symptom and SUI-TAI(水滯) symptom of children. Therefore, we aimed to investigate clinical characteristics of children by night-eating symptom status. Methods : Parents were asked to give a detailed answer to a systemized medical history questionnaire concerning night-eating habit, gastrointestinal symptom and SUI-TAI symptom of their children. Medical records of 28 children treated in the Department of Pediatrics, Hospital of Oriental Medicine, were the subject of this study. Clinical characteristics of two groups of children who with no night-eating habit and frequent night-eating group(eating at night more than 3 times per week) were analysed. In addition, the correlation analysis between clinical characteristics were performed. Results : Children with frequent night-eating habit(n=7, more than 3 days of night-eating a week) were observed to have more aggravated gastrointestinal symptom and SUI-TAI symptom compared with those without night-eating habit(n=13). In parallel, the association of gastrointestinal symptom and SUI-TAI symptom was demonstrated(n=28). Conclusions : It is notable that deranged gastrointestinal function and aggravated SUI-TAI symptom were observed among children generally regarded as healthy. Therefore, endeavors to correct night-eating habit as well as to treat aggravated gastrointestinal and SUI-TAI symptoms are needed for the promotion of health of children.

This study examines the dietary, exercise, and other daily habits of Daegu residents and how these relate to the residents' perception of their own health status, and comparatively analyzes the lifestyles and daily habits of those who perceive themselves to be healthy and those who do not. This research study used Inbody 230(Body composition analysis, Biospace, Korea) to make body and health measurements such as body composition and obesity index. Also, included in this study was a survey on the lifestyle patterns of the residents. The data from this survey was analyzed with SPSS. The results show that among the residents of Daegu, those who perceive themselves to be healthy have lower body fat and are less obese on average. With respect to dietary habits, those who believe themselves to be healthy have more regular dietary habits such as rarely skipping a meal than those who do not believe themselves to be healthy. In addition those who say they are healthy exercise more frequently and for a longer duration than those who say they are not healthy. As for daily habits, those who report they are healthy show greater satisfaction with life and suffer less from stress than those who report themselves to be unhealthy. This study demonstrates that in order to improve people's health in Korea, good dietary, exercise and daily habits need to be emphasized. Additionally, health education and health awareness programs need to be established in each region. Follow-up studies should be conducted afterwards.

Objective : Recently, there is an increasing trend of attachment to physical appearance of individuals in many persons with spread of social concern through mass communication. Domestically, several studies has been performed, but they were limited to obesity mainly for juveniles or female college students. Therefore, purpose of this study were to standardize Body image dysmorphic disorder examination self report with male and female college students in Cheonnan area. Methods : This study were total 825 college students in Cheonan area. Subject group are consist of 393 males (47.6%) and 427 females (51.8%), and the mean age was $22.28{\pm}3.24$ years old. Results : The BDDE-SR had adequate internal consistency (Cronbach's alpha=.93) and test-retest (r=.82) and interator reliability. Four factors were extracted by factor analysis with the Varimax rotation. They were 'the camouflage and comparison factor', 'the self-consciousness and negative self-evaluation factor', 'the avoidance factor', and 'the distressing and embarassment factor'. The total score of BDDE-SR was $50.8{\pm}27.1$, female's score ($59.2{\pm}25.5$) was statistically higher than male's score ($41.85{\pm}25.84$). Conclusion : It is considered that BDDE-SR is reliable instrument for body image dissatisfaction, provided correct information in predicting clinical status of Body dysmorphic disorder that is most largely influenced by individual psychologic factor and family system.

BACKGROUND/OBJECTIVES: Emerging evidence shows that eating breakfast and breakfast types may be associated with health outcomes and dietary intakes in various populations. The aim of this study was to investigate the association between breakfast types in Korean adults with their daily nutrient intakes and health outcomes. SUBJECTS/METHODS: A total of 11,801 20- to 64-year-old adults (age $42.9{\pm}11.8$ yrs [$mean{\pm}standard$ error of the mean]; male 41.1%, female 58.9%) in 2007-2009 Korean National Health and Nutrition Survey data were divided into 5 groups based on breakfast types in a 24-hr dietary recall: rice with 3 or more side dishes (Rice3+, 35.3%), rice with 0-2 side dishes (Rice0-2, 34.73%), noodles (1.56%), bread and cereal (6.56%), and breakfast skipping (21.63%). Daily nutrient intakes and the risk of metabolic syndrome were compared among five groups. RESULTS: Compared with Korean Recommended Nutrient Intake levels, the breakfast-skipping group showed the lowest intake level in most nutrients, whereas the Rice3+ group showed the highest. Fat intake was higher in the bread and noodle groups than in the other groups. When compared with the Rice3+ group, the odds ratios for the risk of obesity and metabolic syndrome were increased in the breakfast skipping, Rice0-2, and noodle groups after controlling for confounding variables. CONCLUSIONS: The rice-based breakfast group showed better nutritional status and health outcomes when eating with 3 or more side dishes. Nutrition education is needed to emphasize both the potential advantage of the rice-based, traditional Korean diet in terms of nutritional content and the importance of food diversity.

Underreporting patterns by the level of obesity have not been fully assessed yet. The purpose of this study was to examine the differential underreporting patterns on cardiovascular risk factor, macronutrient, and food group intakes by the level of Body Mass Index (BMI). We analyzed cross-sectional baseline nutritional survey data from the population-based longitudinal study, the Healthy Women Study (HWS) cohort. Study subjects included 538 healthy premenopausal women participating in the HWS. Nutrient and food group intakes were assessed by the one-day 24-hour dietary recall and a semi-quantitative food frequency questionnaire, respectively. The ratio of reported energy intake (EI) to estimated basal metabolic rate (BMR) was used as a measure of relative energy reporting status and categorized into tertiles. Overweight group ($BMI{\geq}25kg/m^2$) had a higher ratio of EI to BMR (EI/BMR) than normal weight group ($BMI<25kg/m^2$). Normal weight and overweight groups showed similar patterns in cardiovascular risk factors, nutrient intake, and food group intake by the EI/BMR. Fat and saturated fat intakes as a nutrient density were positively associated with the EI/BMR. Proportion of women who reported higher consumption (${\geq}4\;times/wk$) of sugar/candy, cream and red meat groups was greater in higher tertiles of the EI/BMR in both BMI groups. Our findings suggest similar patterns of underreporting of cardiovascular risk factors, and macronutrient and food group intakes in both normal and overweight women.

Objectives: The purpose of this study is to identify the extent of the health behaviors of juveniles with experience in drug and the extent of their oral health behaviors. Then the impact of such factors on the oral health was analyzed. Methods: The analysis in this study used the raw data from 'The Fifth Korea Youth Risk Behavior Web-based Survey' after getting approval for use from the Center for Disease Control. The research subjects of this study were juveniles with experience in drug. Analysis was done by using 8 socio-demographic variables, 6 health behaviors related variables, 4 oral-health behaviors related variables and 1 oral health related variable. All survey data were analyzed by SPSS WIN 17.0 program. as frequency analysis and logistic regression. Results: The factors that give impact on the oral health of juveniles with drug experience were found as: gender, academic year, study grade, school type, school class, city scale, economic status, residential type, experience in alcohol, experience in smoking, obesity, frequency of medium-level physical exercise, eating breakfast frequency, hours of sleeping, number of tooth-brushing in one day, brushing teeth after lunch frequency, experience in dental treatment and experience in oral health training. Conclusions: In order to improve the oral health of juveniles with drug experience, health behaviors such as stop-smoking, stop-drinking and regular physical exercise are recommended. In addition, they should stop using drugs that threats their oral health. The development of nursing intervention to maintain the continuous enhancement of their oral health is also required.

This study was conducted to investigate the evaluation of nutrition and exercise education program on weight control for obese children. The subjects of this study were 28 obese children and their parents living in Geyongnam area. The weight control program consisted of exercises for children and nutrition education for both children and their parents. The BMI values of the children were significantly reduced from $27.96\;kg/m^2$ to $27.22\;kg/m^2$ after 11 weeks (p < 0.001) and to $27.65\;kg/m^2$ after one year. Dietary habits and exercise patterns were also changed positively. For the children, while the frequency of eating breakfast and appropriate chewing habits were increased, the percentages of eating in inappropriate position and the frequency of buying snacks were decreased (p < 0.001). In terms of exercise, the proportion of doing exercise more than 30 minutes, participating in physical activity classes actively, and walking rather than taking a car were significantly increased. Nutrition knowledge of both the student and parent respondents were significantly increased when measured immediately after the education and even a year after compared to their knowledge status measured before the program (p < 0.001). Both the students (82.1%) and parents (96.4%) were satisfied with the overall weight control program. Exercise therapy was chosen as the most beneficial content. Reparticipation intention was comparable between the students (28.6%) and their parents (67.9%). A year after survey results revealed that 71.4% of students controlled their weight by doing regular exercises (55.0%) and controlling overeating (45%). Parents often applied healthy cooking methods (89.3%) and low calorie menus (64.3%), which they learned from nutrition education. Most parents perceived that the weight control program was helpful for their children (89.3%) and themselves (92.9%) as well.
