Objectives: The purpose of this study was to explore coordination strategy through reviewing policies, action plans and acts related to diet, nutrition and obesity from many sectors in Korea, and to develop a possible multi-sectoral approach. Methods: Literature reviews and empirical findings for ongoing international and domestic policies/programs on diet, nutrition and obesity in Korea. Results: Central and local governments have various policies/programs and related acts to improve nutrition and to reduce obesity. Meanwhile, those governments' activities are frequently criticized to be more coordinated in order to achieve their aims. Activities on nutrition and obesity prevention have interdepartmental characteristics but are scattered through six Ministries (including the Ministry of Health and Welfare, Ministry of Education, Ministry of Agriculture, Ministry of Employment and Labor, Ministry of Culture and Sports, and Ministry of Food/Drug Safety) and 27 Acts such as 'Nutrition Management Act', 'Health Promotion Act', 'Diet Education Support Act'. As a result, a number of areas, especially dietary guidance, nationwide surveys, education programs seem to overlap. Conclusions: Inter-ministerial coordination mechanism should be established to enforce multi-sectoral engagement and cooperation in implementing policies/programs on nutrition and obesity prevention. Furthermore, functions of the Ministries should be reorganized and coordinated in reference to other countries' experiences.

Objectives : Obesity is currently an epidemic in Korea, and sleep duration is thought to be one of the risk factors for obesity. The objective of this study was to test the hypothesis that short sleep duration is associated with obesity in Korean adults. Methods : The data from the 2001 Korean National Health and Nutrition Survey were used, and 6,174 subjects aged $18{\sim}80$ years were included in the analysis. Sleep duration was measured using information obtained from self-reported questionnaires. Obesity, the main outcome variable, was measured according to body mass index. Multiple regression modeling was used to adjust for potential confounding variables. Results : The study results revealed a negative association between sleep duration and body mass index among Korean adults. These associations persisted after controlling for the potential confounding variables. Conclusions : These findings support the hypothesis that sleep duration is associated with obesity in Korean adults. In addition, these observations support earlier experimental sleep studies and provide a basis for future studies on weight control intervention by increasing the amount of sleep.

This study was to investigate antiallergic contact hypersensitivity of the polyphenol fractons isolated from persimmon leaves (Diospyros kaki folum). The result of the allergic contact dermatitis is a common skin disease resulting from specific immunologic sensitization due to topically applied allergens. Here the contact hypersensitivity was assayed and obdominal skin morphological changes including mast cells were examined. At contact hypersensitivity assay, less right ear swelling occured in the polyphenol fraction I, II and III groups compared to the control group. The number of mast cells was significantly decreased in the sample groups than the control group.

Objectives : A hospital-based case-control study was conducted to evaluate the role of obesity in the development of colorectal cancer. Methods : Three hundred and twenty four histologically confirmed female colorectal cancer cases and 26,998 non-cancer controls were selected from patients invited to the Aichi Cancer Center, Nagoya, Japan between 1989 and 1995. Information concerning demographic factors, medical history, family medical history, reproductive factors and dietary factors were obtained from self-administered questionnaires and medical records. The effects of weight and body mass index to colorectal cancer were examined using multiple logistic regression to control for other risk factors. Results : There was no significant association between female colorectal cancer and obesity. Heavier weight adjusted for height or body mass index did not increase the risk of colorectal cancer. Conclusions : These results suggest that there is no association between colorectal cancer risk and obesity in women.

Objectives: This study was performed to identify the socioeconomic factors, the psychosocial factors and the heath behavior factors that have an influence on abdominal obesity, as measured by using the waist circumference. Methods: Data was obtained from individuals aged above 20 years who had their waist circumference measured on the Korean National Health and Nutrition Examination Survey 2001, which was a cross-sectional health survey. Results: Regression analysis of the factors that affect abdominal obesity showed that the education level, income, smoking, duration of smoking, drinking consumption, frequency of exercises and sleeping were the associated factors for abdominal obesity. For men, the duration of smoking, education level, income and drinking consumption were the associated factors for abdominal obesity. For woman, the education level, income, duration of smoking, drinking consumption and frequency of exercise were the associated factors for abdominal obesity. Conclusions: Abdominal obesity is a risk factor for morbidity and mortality, and it is associated with chronic diseases, including cardiovascular disease and diabetes. Based on the findings, it is essential to modify heath behaviors for preventing abdominal obesity, which is a condition associated with the incidence of chronic disease.

제2형 당뇨병은 인슐린 저항성과 인슐린 분비능의 장애에 의해서 복합적으로 나타나는 대사성 증후군 중 하나이다. 인슐린 저항성은 용어에서도 알 수 있듯이 인슐린 신호전달의 저하로 인한 인슐린 작용 감소가 나타나고 이는 인슐린 분비가 증가하더라도 포도당 이용은 감소된 상태이다. 인슐린 분비능은 직접적으로 인슐린 작용과는 무관한 것처럼 보이지만 자세히 살펴보면 인슐린 분비능의 중요한 역할을 하는 췌장 베타세포의 성장과 생존은 인슐린/IGF-1 신호 전달과 밀접한 관계가 있으므로 인슐린 분비능도 인슐린/IGF-1 신호전달과 관련이 있다. 그러므로 인슐린/IGF기 신호전달의 장애는 제2형 당뇨병의 병인에 매우 중요한 요인이다. 그러므로 제2형 당뇨병을 효과적으로 예방 또는 치료하기 위해서는 근육, 지방세포와 간등에서 인슐린 신호전달을 향상시켜 포도당 이용을 증가시키고, 시상하부에서 인슐린 신호전달을 향상시켜 식욕을 적절하게 조절할 수 있도록 하여 과체중이나 비만의 발생을 방지하고 췌장의 베타세포에서 인슐린/IGF-1 신호전달을 향상시켜 베타세포의 성장과 생존을 향상시켜 포도당에 대한 인슐린 분비 능을 촉진시키는 것이다. 최근에 FDA에서 승인받은 Exenatide는 glucagons like peptide-1 receptor agonist로 시상하부에 작용하여 식욕조절도 하고 췌장의 베타세포에서 IRS2의 발현을 증가시켜 인슐린/IGF-1 신호전달을 향상시켜 insulinotropic 작용을 가지는 것으로 알려졌다. 이 Exenatide는 도마뱀의 독침에서 분리한 peptide로 천연물로부터 유래된 약물이므로 천연물로부터 제2형 당뇨병을 치료할 수 있는 약물을 발견할 가능성은 매우 높으므로 이에 대한 연구는 체계적으로 이루어져야 하겠다.

This study was performed using animals to confirm the effect of tourmaline-ionized water (TIW) the properties of which were changed by tourmaline energy and electric discharge. In the ICR mice fed high-fat diet, body weight increasing rate of the TIW-treated group (Exp) was generally decreased and moreover exhibited significance at 11th week (P<0.05) compared with the control (Con) group fed distilled water, although water intake of the Exp group was lower than that of the Con group. In the ICR mice with $CCl_4$-induced hepatotoxicity, AST and ALT activities of the Exp group were not significant but showed some decreasing trend, and histological damage of liver was less compared with thatof the Con group. On the study of ethanol-induced hangovers in Sprague-Dawley rat, blood alcohol concentration was significantly decreased (P<0.01), activity of GST, antioxidant enzyme related to the alcohol metabolism, was increased in liver tissue (P<0.05), and AST and ALT show a tendency to be decreasedin the Exp group. These results suggest that drinking TIWhas not only some obesity preventing effect but also an alcohol detoxification effect and liver protecting effect in vivo. It is supposed due to a structural change of water cluster and a property which maintains the changed structure through tourmaline energy and electric discharge. Therefore, TIW has a potentiality to be developed as functional water with several beneficial effects as well as for daily drinking, but further study on the mechanism related with efficacy will be necessary.

We investigated the anti-obesity effects of small colored potato extracts by high pressure water extraction process on body weight, plasma lipid levels in high-fat diet-induced obese mice. Experimental groups were divided into basal diet only (Normal), high fat diet control (HFD), small colored potato water extracts (CP), and high-fat diet and small colored potato water high pressure extracts (HCP) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the HFD group's serum total cholesterol level of $86.01{\pm}1.16mg/dL$, the levels of the CP and HCP groups were significantly lowered to $80.29{\pm}1.28$ and $77.21{\pm}4.21mg/dL$, respectively. Compared with the HFD group's LDL-cholesterol level of $18.92{\pm}2.44mg/dL$, the LDL-cholesterol levels of the CP and HCP groups were significantly lowered to $13.52{\pm}1.26$ and $12.93{\pm}1.26mg/dL$, respectively. Also, compared to the HFD group's serum triglyceride level of $82.71{\pm}3.94mg/dL$, the level of the HCP group was significantly lowered to $63.24{\pm}6.32mg/dL$. These results suggested that dietary supplementation of small colored potato extracts using high pressure water extraction does not have any adverse effects on the hematological variables, while improving the lipid content and reducing hepatic damage of the high-fat fed rats.

This study was done to investigate the effect of stress on appetite and eating habits, and other health-related behaviors. The subjects of this study consisted of 188 males and 224 females in Ulsan area. The results were as follows: When stressed, 56% (n = 231) of the subjects experienced a change in appetite and of these, 32% (n = 132) experienced an increased appetite. Stress-induced eating may be one factor contributing to the development of obesity. There was a gender-specific response to stress in which women are more likely to use food to deal with stress, whereas men are more likely to use alcohol consumption or smoking. It was found that types of stressors were individual (52.9%), social (50.7%), family relations (34.5%), work demands (34.2%) and physical environment (32.3%). Stress-induced symptoms of the subjects were anxiety (38.3%), headache (36.7%) and neck or shoulder aches (36.2%), and females experienced those symptoms more than males. Those older than 50 years had a higher eating habit score and lower stress score compared with younger subjects. There were significant differences between sex, age, occupation, family type, BMI, exercise, sleeping hours and eating habits or stress level. This study may be helpful in advancing findings in this area to better provide health professionals with appropriate counseling tools to improve the health of all individuals.
