This study is on the etiological factors of the obesity, symptoms of a disease caused by the etiological factors and the method of medical treatment resulted from symptoms of a disease, it is based on Dong-Yi Bo Gam. The conclusion of this study is as follows. 1. The final metabolic of fat is depend on the defensive energy. The shape of fatty layer is changed by the point where the defensive energy is replenish or not. So 'Goin(暠人)' 'Bein(肥人)' and 'Yuckin(肉人)' is made a discriminated and there is defferent between 'Besudaeso(肥瘦大小)' and 'Herlqidaso(血氣多少)'. 2. Etiological factors of obesity is ; essential substance from cereals overcome the primodial energy, spleen and stomach are strong at once, spleen and stomach are weak at once, spleen is disturbed by evil energy, retention of phlegm and fluid, muscle is weak, blood is excess but energy (qi)is weak, hua-sid(華食) eating the sweat food very often, a rich fatty diet. 3. To investigate each syndrome as etiological factons, essential substance from cereals overcome primodial energy is divided into two case: one is the food increase itself because of the weakness of stomach energy (qi), the other is not to digest the food because liver overact spleen by seven emotion. The obesity because of strengthen of the spleen and stomach at once do not feel hungry very well and spleen and stomach do not damaged easily by overacting. The obesity because of weakness of spleen and stomach at once, and disturbace in spleen cause by evil energy, gain the weight even if they eat food a little. Also it is hard to move four limbs. Weakness of muscle is weakness of spleen and stomach. Weakness of muscle is caused by weakness of spleen and stomach. That is the case of faining the weight because of eating food with an empty stomach. The obsity caused by retention of fluid has intestine rumbling and gain the weight suddenly. 4. The method of medical treatment fallowing to the etiological factors: The food is inclined to increase itself caused by weakness of stomach energy, In case of the obseity caused by this phenomenon. We can use Decoction for Reinforcing Middle wanner and Replenishing Qi(補中益氣湯), five tastes il-going-san(左味異功散) and so on. The method of medical treatment on obsity caused by strengthen of spleen and stomach is not referred yet. But we must investigate about using peptic powder(平胃散), ji-chul-huan(枳朮丸) for strengthen of stomach qi (胃氣). If the obesity appear caused by weakness of spleen and stomach and disturbance in spleen as to evil energy, and in the same time stomach qi is weak, we can use li-gong san(異功散). If not only obesity but also indigestion, we can use Decoction for naurishing the stomach and promotion eating(養胃進食湯). If not only obesity but also weakness of spleen and stomach, we can use Decoction for Reinforcing Middle warmer and replenishing Qi(補中益氣湯). The energy being weak, we can use Decoction for six noble drugs(六君子湯). If the obesity appear because of retention of fluid, we can use sin-chul-huan(神朮丸). On the obesit, caused by excess of blood and weakness of qi(血管氣虛), there is not method of mectical treatment yet, but the method of medical treatment that we count of first important maybe to invigorate the spleen and the lung qi and to disperse and recitify the depressed liver energy(疏肝利氣). The method of medical treament about the obesity caused by a rich fatty diet is not mentioned yet, but it is important to improve the lifestyle of food and we think that invigorate the spleen, and the lung-qi(補疏肝氣) and disperse and recitify the depressed liver-energy (??肝利機) amy count of first important. 5.There is useful medicine for weight down for example Herb tea(茶), red bean, wax gourd, etc. 6.The etiological factors of the obesity that revive frequently is weakness of qi(氣虛), from 形成氣衰, deficiency of yang, hasty of qi, damp and so on. The symptoms and sign of a disease that revive frequently to the obesity is appoplexia(中風), leucorrhea, reddish and whitish turbid, feeling of fullness in the upper abdomen, diabetes and so on.

Purpose: This study aimed to identify the general characteristics, chronic diseases, health behavior, mental health, and nutritional status of young-old women based on their vitality. Methods: This study used data from the 2019 and 2021 Korea National Health and Nutrition Examination Survey (KNHANES). The subjects were 1,113 young-old women aged 65 to 74 years old. The health-related quality of life concept with an 8-item questionnaire was used to measure the quality of life. Subjects were categorized into 4 groups (always, often, sometimes, never) based on their vitality. General characteristics, chronic diseases, health behavior, dietary behavior, food intake, and nutrient intake were compared among the groups. Results: Age, education level, household income, employment, fruit intake, dietary supplements, abundance of food, and nutrition labeling recognition were associated with the vitality of the subjects. Young-old women with arthritis, diabetes, and osteoporosis displayed lower vitality. Moreover, subjective health status, exercise, activity restrictions, and average daily sitting hours were related to vitality, while no significant difference was found in vitality between smoking and drinking. In terms of mental health factors, higher vitality was associated with 6-8 hours of sleep, lower stress levels, and reduced depression. The high-vitality group exhibited a higher intake of potatoes, starch, mushrooms, fruits, meat, milk, animal oils, and beverages than the low-vitality group. Additionally, the group with higher levels of vitality showed a higher intake of protein, fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, n-6 fatty acids, dietary fiber, sugars, phosphorous, potassium, magnesium, iron, zinc, and riboflavin. Conclusion: This study suggests that the vitality of young-old women is related to socioeconomic factors, health behavior, mental health, and food intake. To maintain a vibrant lifestyle in elderly women, it is necessary to have social and economic stability, prevent arthritis, diabetes, and osteoporosis, exercise regularly, get sufficient sleep, maintain mental health, and have a balanced diet.

Purpose : The prevalence of obesity in children and adolescents has been rising rapidly in Korea because of changes of diet and lifestyle. As with adults, obesity in children and adolescents can cause diabetes mellitus, hyperlipidemia, cardiovascular diseases and renal diseases. The aim of the present study is to examine the relation of obesity, glomerular filtration rate(GFR) and serum cystatin C concentration in children and adolescents. Methods : Data of 115 children and adolescents aged between 6 years and 20 years without clinical evidence of renal diseases were included in the study. From May 2004 to December 2004, blood samples were collected from children and adolescents who were seen at the Department of Pediatrics at Chungang University Yongsan Hospital. Obesity degrees and body mass indices(BMI) were measured, and GFRs were estimated from Schwartz's formula. Serum cystatin C was measured by particle enhanced nephelometric immunoassay using Behring Nephelometer II. Results : GFRs were significantly different between the obese group(BMI >95 percentile, $145.79{\pm}23.10mL/min$) and the non-obese group(BMI <95 percentile, $134.61{\pm}26.19mL/min$) divided by BMI (P=0.031). GFRs were not significantly different between the obese group(obesity degree >120 percent, $144.29{\pm}23.08mL/min$) and the non-obese group(obesity degree <120 percent, $134.54{\pm}26.57mL/min$) divided by obesity degree(P=0.051), but were significantly different between severe obese group (obesity degree >150 percent, $155.55{\pm}20.40mL/min$) and the non-obese group(P=0.004). GFRs were correlated positively with BMI($r^2=0.037$, P=0.039), but were not correlated significantly with obesity degree($r^2=0.030$, P=0.066). Serum cystatin C concentrations were not significantly different between the obese group and the non-obese group, divided by BMI as well as by obesity degree(P>0.05). Conclusion : Obesity may lead to an alteration of renal hemodynamics such as hyperfiltration, appropriate control and management for obesity is necessary.

This study was conducted to investigate factors affecting the bone density of university students in the Seoul area. Data for food habits, and dietary and health-related behavior was obtained by self-administered questionnaires. BQI (bone quality index) of the subjects was measured by a Quantitative Ultrasound (QUS). The results are summarized as follows. The average height, weight, BMI and osteopenia percentage were 175.4cm, 69.3kg, 22.5 and 15.6% for male students, and 161.5cm, 55.9kg, 21.7 and 34.1%, for female students, respectively. The mean BQI of the subjects was 110.25 (range 60.7 ～ 176.8) in male students and 90.64 (range 52.9 ～ 137.5) in female students. Height and weight were significantly related with BQI in the female group but the relationship with BMI was not significantly related with bone density in either group. BQI was positively affected by nutrition supplement in the male student group. One-side eating, diet, and intake of milk and instant food were not significantly related with BQI in males or females. The results of this study revealed that desirable food habits, dietary behavior and health-related lifestyle may have a beneficial effect on bone density. There should be established a practically and systematically organized nutritional education on optimum body weight, good eating habits, weight bearing exercise and intakes of good quality nutrient for higher bone density level.

This study looked into the obesity status, recognition of obesity, attitude towards obesity, eating and exercise habits, and lifestyles of Korean (n=101) and Japanese (n=123) female college students. All students were 21-years-of age, with an average height of 161 cm and the average weight of 54 kg. Korean female students responded that obesity complicated friendships, and hindered study and exercise. Japanese students did not express these opinions. Both Korean and Japanese students tended to over-consume their favorite food. Korean students ate breakfast about 24.8% everyday, while 48% of Japanese students did; both regularly ate dinner. Snack preference was mainly biscuits. The factor most influencing eating habits were TV advertisement for Korean students (57.4%) and parents for Japanese students (47.2%). Once-weekly exercise was done regularly by 34.7% of Korean students but only 20.3% of Japanese students. The main reason for Korean students to exercise was weight reduction (53.5%), while 78.2% did not exercise because it was tiring. Korean and Japanese students had similar life styles, although stress relief in Korean students was sought through conversations with friends and by reading books or listening to music for Japanese students.

Purpose: Adult Korean men belonging to the main economically active population are known to have long sedentary hours. This study was undertaken to determine the difference and relevance of sedentary hours on the nutrition, diet, and health status of adult men, and to suggest how to prevent health risk factors. Methods: Subjects (n = 1,068) were classified into 4 groups based on their sedentary hours, ranging from the first quartile (Q1) having the least hours spent sitting, to the fourth quartile (Q4) spending the longest hours. Results: Subjects belonging to Q4 had the lowest average age, the largest waist circumference, and the highest level of education. Among those engaged in economic activities, the ratio of white-collar workers was significantly higher in Q4. Accordingly, the rate of not doing high-intensity or moderate-intensity physical activity while working was also the highest in Q4. A significant difference was obtained in the drinking frequency between groups, but this was found to be associated with the average working hours rather than sedentary hours. The proportion of not doing aerobic exercise was higher with longer sitting hours. The highest diagnosis of diabetes (8.8%) was obtained in the Q4 group. Among the factors related to cardiovascular disease, only low density lipoprotein-cholesterol showed a significant difference, with Q4 being significantly higher than Q1. Considering energy and nutrient intake, vitamin B₁ and calcium intake were the lowest in the group with the longest sitting hours, as well as the least consumption of vitamin C than the recommended estimated average requirement. Conclusion: The results of this study suggest that the health and nutritional status of Korean adult men are affected by sedentary hours. This should be recognized as a health risk factor and guidelines need to be developed for sedentary lifestyle management.

There are 3 different hypotheses on how statins may affect bones, through promoting bone formation, inhibiting bone resorption or through anti-inflammatory effect. In the 3 cross-sectional studies above, one showed increase BMD at hip and spine, one showed increase BMD only at mid-forearm and one showed that the risk reduction in fractures is not explained by the changes in BMD however, all 3 studies showed a decrease in risk of fracture associated with statins. In the 2 prospective cohort studies, one showed the use of statins was not associated with BMD at any skeletal site or decreasing the risk of fracture, and the other showed statins except pravastatin decreased in risk of vertebrate fracture but not affecting lumbar spine BMD. All of case-control studies indicated reduction in fracture risk but did not provide any data regarding BMD. 2 of the randomized, controlled studies showed no significant reduction in fracture risk as well as statins' effects on BMD. Finally, one longitudinal study showed statin use reduced fracture risk and increased BMD. Among the conflicting results shown above, even when statin use was shown to increase BMD, it does not seem to account for the reduction in fracture risk. There may be different ways that statins affect bone other than those hypotheses proposed above. Many studies seem to agree that pravastatin does not have any effect on bone. Some studies suggested that the reason statins did not achieve clinically significant increases in BMD in some studies, is due to the low affinity of statins on bone; statins are designed to act in the liver therefore their effective concentration in extrahepatic tissue is low. The limitations to those studies discussed above. Many studies did not account for the change of lifestyle while subjects' were on statins. Increases in weight bearing exercise and changes in diet might affect BMD and thus reduce risk of fractures. Mental alertness and vision acuity might prevent falls from occurring; many statin-users in the studies were young so the risk of fractures from falls would be decreased. Almost all of the studies failed exclude patients with neurological problems. During study periods, many subjects may have been started on drugs for diseases that usually occur with aging which could cause drowsiness and lead to falls. The sample sizes used in some of the trials were small and the duration of treatment and follow up might not have been long enough to see clinically relevant results.
