It is important for young adults to establish good dietary behavior for healthy life. The prevalence of obesity in college students has increased gradually. The obesity is one of the most prevalent health problems in S. Korea. Moreover, obesity is closely related with the disease such as cardiovascular disease, diabetes mellitus. The purpose of this study was to evaluate health practice, serum components and nutrient intake of the college students according to Body Mass Index (BMI) level. 400 male and female freshmen students in 4 year university located near to Seoul metropolitan area were surveyed respectively through the health check-up procedure for college entrance in February. Survey was carried out for them by questionnaires, including a 24-hour dietary recall and anthropometric measurements. Blood samples were obtained while fasting. Nutrient intake was expressed by DDS(Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). Nutrition level was analyzed by Can-Pro (Korea Nutrition Association). And for the quantity intake, percentage ratio against daily requirement(by KDRIs) and MAR(Mean Adequacy Ratio) were calculated. Underweight group($BMI<18.5kg/m^2$), normal weight group($18.5) and overweight group($BMI<23.0 kg/m^2$) were 18.5%, 61.2% and 19.3% respectively. Nutrient intake levels and food intake status were not significantly different among three groups. The mean nutrient adequacy ratio (MAR) was not significantly different by BMI status. Nutrient intakes of calcium, iron, and riboflavin were especially low for all the students. Overweight group showed high blood pressure(120.9/79.3 mmHg) compared with the underweight group (116.4/ 75.8mmHg) but the difference was not significant. The serum triglyceride level in overweight group (94,0mg%) was higher than that in normal (70.9mg%) or underweight group(70.8mg%)(p<0.05). HDL-cholesterol level in overweight (43.8 mg%) group was not significantly different from that in underweight group (45.9mg%). BMI was positively correlated with blood pressure, hemoglobin, and the intake of total fat and cholesterol. But it was negatively correlated with HDL-cholesterol level. With these results overweight group is closely related with the cardiovascular disease risks, such as high blood pressure and high triglycerides and cholesterol. Thus, a health intervention program including weight control is required for young adults.

Obesity is defined as excessive storage of energy in the form of fat resulting in adverse effect on healthy and longevity. Some data have shown increased incidence of hypertension, diabetes, hypercholesterolemia in overweight individuals and other disorders such as joint disease, cancer have been also associated with obesity. Recently, various commercial diet programs have been introduced for weight reduction without scientific evaluation for clinical effect and safety. The diet program must be based on a sound and scientific rationale and also be safe and nutritionally adequate. Pulmuone $diet^{(R)}$ is a calorie-restricted commercial diet-food, which contains adequate nutritients. The efficacy and safety of Pulmuone diet were evaluated in 28 normal healthy obese females in a prospective study. Each volunteer was placed in 3-week diet program. To observe weight reduction effect, body weight, TSF and AMC were measured every week. To account for safety of this program, blood chemistry test, blood pressure and side effects were monitored every week. Mean body weight was reduced by 3.24kg following diet program, which is statistically significant(P < 0.05) and this weight reduction was related to reduction in fat weight and not muscle weight as shown by the results of TSF and AMC Blood chemistry was not influenced by this program, but blood pressure was significantly reduced following this program. Thought diet program was generally well tolerated in most volunteers, the most frequent side effects are constipation, dizzness and headache. In conclusion, Pulmuone $diet^{(R)}$ program seems to be safe and effective for weight reduction in normal healthy obese females.

For the estimation of prevalence state of major chronic adult disease and their relationships with drinking and smoking habits in the Korean employees, we analyzed a medical check-up data of 155,799 subjects that was accumulated during the year of 2008. In age and sex distribution of the sample, male subjects were 106,229 and female 51,827 showing the ratio of 2:1 and the majorities were 30s and 40s covering 70.7% of the total. The prevalence rates of major chronic diseases were obesity 29.8% (male 38.3%, female 12.3%), hypertension 4.1%, HBV carrier inactive 3.3%, diabetes mellitus 2.9%, hypothyroidism 1.7% (male 1.3%, female 2.4%), hyperlipidemia 1.1%, hyperthyroidism 1.4% (male 1.1%, female 2.1%), osteoporosis 1.4% (male 1.4%, female 1.4%), anemia 0.9% (male 0.3%, female 2.0%) and renal disease 0.9%. The frequency of and volume of drinking in male group were 4.6 times and 7.5 times higher than female group respectively. The 33.8% of the workers were smoking currently. In the serological tests, all the items such as AST, ALT, ${\gamma}-GTP$, LDH for liver function, Cholesterol, TG, uric acid for hyperlipidemia and BP systolic, Fasting blood sugar, BMI for metabolic syndrome were significantly higher in the more drinking and more smoking groups than other groups (p<0.001). The higher prevalence rates in male group in the liver disease seems to be strongly related with the drinking and smoking habits in male employees. We suggest that employees should rather relying on leisure or hobbies than drinking and smoking for the stress relief.

Generally fatty liver is attributed either to chronic alcoholism, diabetes mellitus, or obesity. Based upon this commonly held clinical brief, this study was conducted to investigate the contributing factors of fatty liver and odds ratio (OR) of known contributing factors. A sample of 310 male participants, who visited at Seoul Paik Automated Multiphasic Health Testing System from November 1991 to December 1991, was separated into 112 cases and 198 controls by ultrasonographic fin ding. There were statistically significant difference between fatty liver and normal in triglyceride (TG), body mass index (BMI), alanine aminotransferase (ALT), high density lipoprotein cholesterol (HDL-C), fasting blood sugar (FBS), alcohol consumption, low density lipoprotein cholesterol (LDL-C), total cholesterol, gamma-glutamyl transferase ($\gamma$-GT), duration of alcohol intake and alkaline phosphatase (Alk.P)(P<0.01, P<0.05). The statistically significant elevated odds ratio were noted for TG (4.48, confidence interval (CI) 2.66-7.55, P=0.000), alcohol consumption(3.24, CI 1.56-6.23, P=0.002), BMI(3.05, CI 1.87-4.97, P=0.000), and FBS (2.59, CI 1.53-4.40, P=0,000). In summary, it is suggested that the fatty liver could be preventive by avoiding such deleterious factors as high fat diet, alcohol and obesity.

This study was performed to develop a K_diet-index based on the definitions and characteristics of traditional Korean food. The Korean Food Pattern Index (K_diet-index) for diseases was applied using dietary data from the 2017 National Health and Nutrition Examination Survey (KNHANES) and the association between K_diet-index and metabolic disease was confirmed. The study subjects were 1,971 Korean adults aged >40, and the components were classified according to 14 criteria used to establish the K_diet-index. Main ingredients up to the top 3 were designated using dish names, ingredients, and contents using KNHANES dietary data. K_diet-index was classified using scores of ≤3 points, 4-7 points, and ≥8 points and total K_diet-index were calculated by summing dietary scores. Correlations between K_diet-index and obesity, hypertension, hyperlipidemia, and diabetes were analyzed. The odds ratio (OR) and 95% confidence interval (CI) for obesity were 0.531, 0.385~0.732 and for elevated cholesterol (≥240 mg/dL) indices were 0.471, 0.282~0.788, respectively, which showed a significant decreased in the risk for each disease for K_diet-index of ≥8 points. This study confirms that metabolically related clinical results improved significantly as K_diet-index increased and that higher Korean food pattern indices are associated with lower risks of metabolic disease

Amomum cadamomum Linne (ACL) has long been utilized against the inhibited qi movement related diseases such as dyspepsia, acute gastroenteritis, vomiting and diarrhea in Korean medicine. We speculated that ACL could improve the metabolic disorders such as obesity and type 2 diabetes through removing the phlegm-dampness and promoting the qi movement or stagnation. This study was designed to investigate effects and molecular mechanisms of ACL extract on the improvement of adipocyte dysfunction induced by TNF-α in 3T3-L1 adipocytes. Potential roles of ACL extract in the lipogenesis, inhibition of inflammatory cytokines and insulin resistance, were investigated in this study. Also, we examined the adipose genes and signaling molecules related to insulin resistance and glucose uptake to elucidate its mechanism. Our data demonstrated that TNF-α significantly incresed the release of lipid droplets and the production of MCP-1 and IL-6 from adipocytes. In gene expression, TNF-α reduced the expression of aP2, PPARγ, C/EBPα, GLUT4, and IRS-1 related to lipogenesis and insulin sesitivity, while TNF-α increased the expression of MCP-1 related to inflammation. In addition, TNF-α down-regulated the PPARγ and IRS-1 protein and up-regulated the IRS-1 Ser307 phosphorylation. These alterations induced by TNF-α were prevented by the treatment of ACL extract. Thus, our results indicate that ACL extract can be used to prevent from the TNF-α-induced adipocyte dysfunction through insulin and PPARγ pathways.

This study was performed to investigate the effects oi nutrition education program in physical health, nutritional status and health-related quality of life (HRQoL) of the Elderly in Seoul. Nutrition education program was consisted of healthy eating, prevention and diet therapy of obesity, diabetes, cardiovascular disease, and osteoporosis. Seventy eight free-living elderly people (13 male, 65 female), aged ${\geq}60 $ years participated in this program. Before and after nutrition education program, we surveyed the general characteristics, physical health, general health, nutrition status, and health-related quality of life to the subjects. All the subjects were divided into program completers (N=47) and noncompleters (N=31). All the data were analyzed by student t-test, chi-square test, paired t-test, and marginal homogeneity test using SPSS 9.0 version at p<0.05. After nutrition education program, physical activity and ADL maintained, however IADL improved in program noncompleters. In eating habits, 'slow eating' significantly improved in program completers in program completers. Nutrition knowledge and recognition scores were significantly increased in both groups, and accuracy score was significantly increased in program completers. However, nutrient-intakes of %RDA were not significantly changed in both groups, and it seemed to be more influenced by other factors such as 'family income' or 'family type' than by the nutrition education program. In HRQoL, social functioning was improved after nutrition education program in both groups (p<0.05). The nutrition education program has more effects on the program completers than on the noncompleters, and it is also needed social supports for the Elderly to fulfill their nutrient requirements.

OLETF (Otsuka Long-Evans Tokushima Fatty) rats are characterized by obesity-related insulin resistance, which is a phenotype of type 2 diabetes. Sulfonylurea drugs or benzoic acid derivatives as inhibitors of the ATP-sensitive potassium $(K_{ATP})$ channel are commercially available to treat diabetes. The present study compared sulfonylurea drugs (glimepiride and gliclazide) with one of benzoic acid derivatives (repaglinide) in regard to their long-term effect on ameliorating insulin sensitivity in OLETF rats. Each drug was dissolved and fed with drinking water from 29 weeks of age. On high glucose loading at 45 weeks of age, response of blood glucose recovery was the greatest in the group treated with glimepiride. On immunohistochemistry analysis for the Kir6.2 subunit of $K_{ATP}$ channels, insulin receptor ${\beta}$-subunits, and glucose transporters (GLUT) type 2 and 4 in liver, fat and skeletal muscle tissues, the sulfonylurea drugs (glimepiride and gliclazide) were more effective than repaglinide in recovery from their decreased expressions in OLETF rats. From these results, it seems to be plausible that $K_{ATP}$-channel inhibitors containing sulfonylurea moiety may be much more effective in reducing insulin resistance than those with benzoic acid moiety. In contrast to gliclazide, non-tissue selectivity of glimepiride on $K_{ATP}$ channel inhibition may further strengthen an amelioration of insulin sensitivity unless considering other side effects.

BACKGROUND/OBJECTIVES: Hyperglycemia is a major cause of diabetes and diabetesrelated diseases. Sodium butyrate (NaB) is a short-chain fatty acid derivative that produces dietary fiber by anaerobic bacterial fermentation in the large intestine and occurs in foods, such as Parmesan cheese and butter. Butyrate has been shown to prevent obesity, improve insulin sensitivity, and ameliorate dyslipidemia in diet-induced obese mice. Therefore, this study examined the effects and mechanism of NaB on the secretion of inflammatory cytokines induced by high glucose (HG) in THP-1 cells. MATERIALS/METHODS: THP-1 cells were used as an in vitro model for HG-induced inflammation. The cells were cultured under normal glycemic or hyperglycemic conditions with or without NaB (0-25 μM). Western blotting and quantitative polymerase chain reaction were used to evaluate the protein and mRNA levels of nuclear factor-κB (NF-κB), interleukin-6, tumor necrosis factor-α, acetylated p65, acetyl CREB-binding protein/p300 (CBP/p300), and p300 using THP-1 cells. Histone acetyltransferase (HAT), histone deacetylase (HDAC), and pro-inflammatory cytokine secretion activity were analyzed using an enzyme-linked immunosorbent assay. RESULTS: HG significantly upregulated histone acetylation, acetylation levels of p300, NF-κB activation, and inflammatory cytokine release in THP-1 cells. Conversely, the NaB treatment reduced cytokine release and NF-κB activation in HG-treated cells. It also significantly reduced p65 acetylation, CBP/p300 HAT activity, and CBP/p300 gene expression. In addition, NaB decreased the interaction of p300 in acetylated NF-κB and TNF-α. CONCLUSIONS: These results suggest that NaB suppresses HG-induced inflammatory cytokine production through HAT/HDAC regulation in monocytes. NaB has the potential for preventing and treating diabetes and its related complications.

Object : The purpose of this study was to evaluate the relationship between pattern identification (PI) and stroke risk factors, such as hypertension, diabetes mellitus, dyslipidemia, stroke history, obesity, abdominal obesity and metabolic syndrome. Methods : 46 patients with acute ischemic stroke were recruited from May 2012 to November, 2012. We analyzed the data of 32 patients, and pattern identification was identified by resident and specialist of Korean medicine. We analized patient's PI and risk factor by Fisher's exact test. Results : We found that Dampness-phlegm group was more related with patient's metabolic syndrome than non Dampness-Phlegm group. And Yin deficiency group had less relationship with patient's metabolic syndrome, obesity, abdominal obesity and dyslipidemia than non Yin deficiency group. Conclusions : According to the analysis, these results provide evidence for relationship between the Dampness-phlegm group, Yin deficiency and metabolic syndrome.
