본 연구에서는 MU-C와 MU-CA에 대해 3T3-L1 세포를 이용하여 지방분화 억제 효과와 고지방식이를 통해 비만을 유도한 마우스에서 항비만 효과를 조사하였다. 3T3-L1 세포를 adipocyte로 분화 시키면서 무청 추출액을 세포에 처리한 후 Oil red O 염색법을 통하여 지방축적을 비교해 본 결과 Control 대비 MU-C와 MU-CA 처리군에서 세포 지방 축적이 현저히 감소 되었으며, MU-C 처리군이 MU-CA 처리군에 비해 유의적으로 억제되었음을 확인하였다. 6주간의 동물실험을 통한 무청 추출액 투여 후 체중 측정 결과 MU-C군과 MU-CA군 순으로 HFD군에 비해 체중 증가를 감소시키는 효과는 보였으며, 시료 투여 4주차부터 HFD군에 비해 시료 투여군에서 유의적으로 체중이 감소함을 확인하였다. 또한, MU-C군과 MU-CA군 순으로 HFD군에 비해 지방량이 적음을 확인할 수 있었다. 실험 종료 후 간 무게와 지방무게를 측정한 결과 절대 장기 무게와 상대 장기 무게 모두 MUC군과 MU-CA군 순으로 HFD군에 비해 유의적으로 무게가 감소하였다. 혈중 TG, TC 함량 측정 및 동맥경화지수와 심장위험도 지수 계산 결과 MU-C군과 MU-CA군 순으로 HFD군에 비해 유의적으로 감소 하였으며, 혈청 내 간 기능 효소(ALT, AST) 측정 결과 또한 MU-C군과 MU-CA군 순으로 HFD군에 비해 유의적으로 감소하였다. 병리조직학적 분석 결과 HFD군의 경우 지방축적 정도 심하였고, 일부에서 염증과 풍선도를 볼 수 있었다. MU-C군과 MU-CA군에서는 일부 간세포에 염증과 지방이 침착된 것을 확인하였으며, HFD군에 비해 간세포가 균일하게 배열되어 있고 지방 축적 정도는 감소된 모습을 관찰하였다. 지방세포의 경우도 대체적으로 균일한 크기에 지방세포를 가지고 있음이 관찰되었다. HFD군 비해 MU-C군과 MU-CA군 순으로 지방세포의 크기가 유의적으로 감소를 나타내었다. 이러한 실험 결과를 보았을 때 체중 변화, 지방무게, 혈중지질, ALT, AST 수치에서 열수 추출한 MU-C군이 MU-CA군에 비해 유의적으로 감소하여 MU-C군이 항비만 효과에 더 효과적인 물질로 확인된다. 이는 유기산 첨가 시 수용성 식이섬유와 불용성 식이섬유가 분리되어 수용성 식이섬유 보다 불용성 식이섬유의 함유량이 증가에 따른 성분 차이로 판단되며(Kim, 2011), 가수분해를 통한 생리활성 물질의 추출 수율 증가로 인해 MU-C군이 비만 예방 효과에 따른 건강기능식품 소재로 적극 활용될 수 있을 것으로 판단된다.

Purpose: This study identified effects of dietary and physical activity interventions including dietary interventions or physical activity interventions alone or combined dietary-physical activity interventions to improve symptoms in metabolic syndrome including abdominal obesity, high triglycerides, low high density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose through meta-analysis. Methods: Articles on metabolic syndrome X published from 1988 to 2013 were searched through electronic databases, Google Scholar, and reference reviews. Methodological quality was assessed by the checklist, SIGN (Scottish Intercollegiate Guidelines Network). Results: In the meta-analysis, there were 9 articles reporting 13 interventions with 736 participants. Using random effect models, the dietary and/or physical activity interventions showed a lower mean difference in waist circumference ( - 1.30 cm, 95% CI: - 2.44~ - 0.15, p=.027). The combined dietary-physical activity interventions showed a lower mean difference in waist circumference ( - 2.77 cm, 95% CI: - 4.77~ - 0.76, p=.007) and systolic blood pressure ( - 5.44 mmHg, 95% CI: - 10.76~ - 0.12, p=.044). Additionally, interventions of over 24 weeks yielded a lower mean difference in waist circumference ( - 2.78 cm, 95% CI: - 4.69~ - 0.87, p=.004) and diastolic blood pressure ( - 1.93 mmHg, 95% CI: - 3.63~ - 0.22, p=.026). Conclusion: The findings indicate that dietary and/or physical activity interventions for metabolic syndrome reduce central obesity with no adverse effects. This finding provides objective evidences for dietary and physical activity management on metabolic syndrome as an efficient intervention.

There are limited data on healthy dietary patterns protective against metabolic syndrome (MetSyn) development. We identified dietary patterns among middle-aged and older adults and investigated the associations with the incidence of MetSyn. A population-based prospective cohort study included 5,251 male and female Koreans aged 40-69 years. At baseline, all individuals were free of MetSyn, other major metabolic diseases, and known cardiovascular disease or cancer. Cases of MetSyn were ascertained over a 6-year of follow-up. Dietary patterns and their factor scores were generated by factor analysis using the data of a food frequency questionnaire. We performed pooled logistic regression analysis to estimate multivariable-adjusted relative risk (RR) and 95% confidence interval (CI) for associations between factor scores and MetSyn risk. Two dietary patterns were identified; (1) a healthy dietary pattern, which included a variety of foods such as fish, seafood, vegetables, seaweed, protein foods, fruits, dairy products, and grains; and (2) an unhealthy dietary pattern, which included a limited number of food items. After controlling for confounding factors, factor scores for the healthy dietary pattern were inversely associated with MetSyn risk (P-value for trend < 0.05) while those for the unhealthy dietary pattern had no association. Individuals in the top quintile of the healthy diet scores showed a multivariable-adjusted RR [95% CI] of 0.76 [0.60-0.97] for MetSyn risk compared with those in the bottom quintile. The beneficial effects were derived from inverse associations with abdominal obesity, low HDL-cholesterol levels, and high fasting glucose levels. Our findings suggest that a variety of healthy food choices is recommended to prevent MetSyn.

BACKGROUND/OBJECTIVES: Urbanization and lifestyle changes have resulted in nutrition transition. Over-nutrition causes obesity increase, although malnutrition still exists. This phenomenon is called a double burden of malnutrition (DBM). This study was conducted to confirm the existence of DBM and to investigate the dietary factors related to DBM in Indonesian adults. SUBJECTS/METHODS: Data for the subjects (51 men and 89 women) who are the adults resided in Malang, Indonesia were collected between July 17 and August 14, 2017, by using questionnaire. Height, weight, waist and hip circumference, blood pressure, blood glucose, total cholesterol, and hemoglobin were also measured for the subjects. RESULTS: The average age of the subjects was 47.2 years. The average height, weight, and body mass index for men were 160.08 cm, 62.6 kg and $25.45kg/m^2$, respectively, and those for women were 148.74 cm, 58.09 kg, and $26.21kg/m^2$, respectively. Of the subjects, 3.6% were underweight, 24.3% were normal or healthy weight, while 72.2% were overweight and obese. Analysis of the dietary intakes revealed high for cereal (7.73 points), but very low for milk (0.25 points) and fruits (0.51 points). Dietary diversity was very few overall (< 5). The occurrence of both anemia (23.6%) and chronic diseases such as hypertension (57.1%), diabetes (12.1%), and hypercholesterolemia (3.6%) was considerably high. The existence of DBM was confirmed by 16.4% of the subjects. DBM was observed significantly higher in women than in men. Dietary diversity and DBM occurrence were inversely correlated. On average, the number of chronic diseases was 1.08 in men and 1.79 in women. Dietary diversity inversely affected systolic blood pressure. CONCLUSIONS: DBM existed in adults in Malang, Indonesia due to inadequate dietary intakes, and a high rate of chronic diseases.

The purpose of this study was to investigate the nutritional status of antioxidant vitamins in relation to serum malondialdehye(MDA) level in postmenopausal women with common occurance of cardiovascular disease(CVD). Data about general characteristics including smoking, drinking and exercise status, dietary intake and serum level of antioxidant vitamins, and serum MDA level were collected from eighty-five postmenopausal women. Mean serum MDA level was 1.62$\pm$0.03nmol/ml, and general characteristics and serum lipid profiles were not significantly different among the three group: low MDA(<1.45nmol/ml), midium MDA(1.45-1.74nmol/ml) and high MDA($\geq$1.74nmol/ml). Total mean vitamin A intake was 472.8$\pm$37.7RE, 68% of RDA, vitamin C intake was 134.3$\pm$8.7mg, 192% of RDA and vitamin E intake was 8.6$\pm$0.5mg, 86% of RDA for Korean. In takes of antioxidant vitamins from the diet were not significantly different among the three groups. However significant negative correlation(r=-0.242, p<0.05) was observed between vitamin E intake and serum MDA level in total subjects. Total mean serum vitamin A, $\beta$-carotene and vitamin C level were 0.59$\pm$0.01$\mu\textrm{g}$/ml, 0.25$\pm$0.01$\mu\textrm{g}$/ml and 9.02$\pm$0.28$\mu\textrm{g}$/ml, respectively. Total mean serum vitamin E and vitamin E/total cholesterol level were 9.15$\pm$0.42$\mu\textrm{g}$/ml and 4.09$\pm$0.17$\mu\textrm{g}$/mg, respectively. Serum antioxidant vitamins levels were not significantly different among the three groups. However serum vitamin C and E level were negatively correlated to serum MDA level. We can conclude that it will be helpful for postmenopausal women with common occurance of CVD to improve nutritional status of antioxidant vitamins by increasing intakes of antioxidant vitamins, especially vitamin C and E.

The purpose of this study was to clarify the dynamic relationships among risk factors of arteriosclerosis and to develop and examine a model which could explain this relationship clearly. Data were collected from medical records of 400 male clients who visited a university hospital located in Inchon for physical examinations, from May 1996 to December 1996. Data were analyzed using the LISREL (Linear Structural Relationship) 8 program. To test the fitness of the hypothesized model, chi-square, RMSR (root mean square residual), GFI (goodness of fit index), CN (critical number) and Q-plot were used. Most of the fitness measurements, except the chi-square showed that the hypothesized model complimented the real data. According to the results, there were trends that obesity and hyperlipidemia were prevalent in heavier smokers, higher alcohol intakers, and groups who excercised less. Also, hypertension was more prevalent in older age, higher alcohol intaker, and higher serum lipid level groups. In contrast to the hypothesis, alcohol intake did not significantly affect serum lipid levels. This might be due to the serum lipid measurements (total cholesterol and trigryceride) used in this study to estimate hyperlipidemia. The direct effect of smoking on hypertension was not significant. However, the total effect of smoking on the hypertension was significant since indirect effects of smoking on hypertension, such as obesity and hyperlipidemia, were significant. The total effect of obesity on hypertension was significant since the indirect effect of obesity on hypertension via hyperlipidemia was significant, although the direct effect of smoking on hypertension was not significant. The degree of explaining hyperlipidemia with smoking, exercise, and obesity was high (60%), however, the degree of explaining obesity with age, smoking, alcohol intake, and exercise was very low (7%). On the basis of these results, high risk factors of arteriosclerosis such as hypertension, hyperlipidemia, or obesity are either directly or indirectly correlated each other. Therefore, it is difficult to predict outcomes for increasing or decreasing the risk factors by simply modulating a factor. Smoking, alcohol, and exercise both directly and indirectly affected major risk factors of arteriosclerosis. Therefore, correcting these variables is required to decrease risk factors. Finally, the relationship among other risk factors which have been known to be related with arteriosclerosis (diet, stress or hereditary) should be clarified in further studies.

The present study was undertaken to investigate the metabolic problems of high carbohydrate and cellulose diets of Korean. Forty males and same number of females of Albino rats, aged $45{\pm}5$days were divided into 95% high carbohydrate (H. CHO)group, 83.8% medium carbohydrate (M. CHO)group, 50% low carbohydrate (L. CHO) group and standard (Stand). group containing 72.2% sugar. Each group was divided into two again-1.55% cellulose group and non-cellulose group, 10 rats each of eight groups in both sexes. Cellulose was added to each of non-cellulose diets in the forms of spinach powder and rice bran. After 14 weeks the rats were sacrificed for chemical analysis and the results were elucidated as follows. (1) H. CHO+Cell. group showed the lowest value in body weight gained and shrinkage of almost all organs, in contrast with this group the L.CHO group showed higher body weight gained than Stand. group. M. CHO+Cell, group showed much the same body weight gained curve as Stand. group. (2) It was observed that cellulose group showed lower F.E.R and P.E.R value than non-cellulose group comparatively. (3) Total nitrogen retention and retention rate were decreaced in H. CHP groups compared with M. CHO or L. CHO groups. (4) The amount of feces was increased due to addition of cellulose to experimental diets and in accordance with the increasing total fecal excretion of nitrogen and glucose was also increased, especially noticeable in fecal glucose excretion. (5) It was noteworthy that serum cholesterol level was decreased due to addition of cellulose in H. CHO group and L. CHO group. (6) M. CHO+Cell. group was designed to reflect the average survey data of Korean diets and there was no significant differences on body weight gained, F.E.R, P.E.R, total nitrogen retention and hematology between M. CHO+Cell. and Stand. group. Total glucose excretion was increased due to dietary cellulose in M. CHO+Cell. group, but it seemed to be no metabolic problems in this group.
