This study aimed to assess the health status based on the anthropometric and biochemical measurements of middle-aged and elderly people living in Andong area. The subjects were 1,384 people (532 males, 852 females) aged 50 years and over (average 62.7 years). The mean anthropometric values for males and females were heights of 163.7 and 151.5 cm; weights 63.6 and 57.3 kg; body mass index (BMI) 23.6 and $24.9kg/m^2$; body fat 21.8 and 31.8%, respectively. Height and weight were lower, however, waist circumference (in female) and BMI were higher than those of the 2001 National Health and Nutrition Survey (NHNS). Obesity incidences of male and female subjects were 28.7% and 47.3% by BMI; 25.8% and 50.8% by % body fat; and 15.6% and 80.9% by waist circumference, respectively. Also, abdominal adiposity was very severe in female subjects of 50s. The mean biochemical measurements of male and female were as follows: systolic and diastolic blood pressure 136.9, 83.8 mmHg and 133.6, 82.5 mmHg; hemoglobin (Hb) 14.3 and 13.0 g/dL; hematocrit (Ht) 44.7 and 39.8%; blood albumin 4.15 and 4.04 g/dL; total-cholesterol 170.0 and 183.1 mg/dL; HDL-cholesterol 43.6 and 42.7 mg/dL; fasting blood glucose 96.7 and 93.0 mg/dL, respectively. Also, the prevalence of biochemically abnormal subjects according to each cut-off point of biochemical measurements were analyzed. The results for male and female were; hypertension 58.0% and 47.2%; iron deficient anemia 19.3% and 20.6% by Hb, 7.2% and 11.9% by Ht; hypoalbuminemia 9.8% and 11.7%; diabetes 12.0% and 10.2%; hypercholesterolemia 19.5% and 30.5%, respectively. From those results we found that hypoalbuminemia, hypertension and hypercholesterolemia were prevalent, and obesity in females of 50s, iron-deficient anemia and diabetes in males of 70 years and over were significant health problems in this area. Therefore, it seems to be necessary to examine their health status periodically and provide the appropriate health and nutrition education program, which includes low sodium intake, balanced diet, exercise and weight control, to prevent the occurrence of chronic diseases.

This study was performed to document the association between obesity, a major risk factor for chronic diseases, and dietary pattern in Korean elderly. The subjects were 595 men and women aged 60-89 years. The subjects were classified into 4 groups based on BMI: under weight, BMI < 18.5, normal weight, 18.5 $\leq$ BMI 22.9; overweight, 23.0 BMI 24.9; and obese BMI $\geq$ 25.0. Dietary intakes by 24-hr recall, blood pressure, anthropometric parameters and health eating index (HEI) were measured. Underweight group was excluded for data analysis doe to small number of subjects, and age-adjusted measurements were compared among normal, overweight and obese groups. The mean anthropometric values for males and females were 23.7 and 24.8 kg/$m^2$ for BMI, 0.90 and 0.86 for WHR and 140.7 and 138.8 mmHg for SBP, respectively. The mean intakes of energy, Ca, vitamin A, vitamin B$_2$, and vitamin E did not meet Korean RDA for elderly. Intakes of fat and cholesterol were low: the percent energy from fat for male and female subjects were 19.1% and 18.1% and mean cholesterol intakes were 208 mg and 152 mg, respectively. Judging by HEI score, dietary quality was better in females than in male subjects. The mean BMI of normal, over and obese groups were 21.4, 23.9, 26.7 kg/$m^2$ in male subjects and 21.6, 23.9, 27.1 kg/$m^2$ in female subjects. WHR, SBP and TSF were increased with increasing BMI No association was found between BMI and nutrient intakes and/or food consumption pattern. However, a tendency was shown that the overweight group reported higher intakes in most nutrients compared to normal and obese groups. This study implies that with increasing BMI, anthropometric risk factors, such as WHR, TSF, and blood pressure were Increased, however, no significant differences were found in nutrient intakes and food patterns. Energy and fat intakes do not seem to be a cause for obesity in Korean elderly.

In this research, we have analyzed the impact factors on the bone mineral density thru the examination of bone density difference in the entire femur, femoral neck and lumbar of adult women before the menopause in accordance with the general features, lifestyle, eating habits, health and body composition. The survey was conducted among adult women before the menopause and older than 30 years based on the data of the National Health and Nutrition Examination Survey carried out in the 4th term (2008-2009) and 5th term (2010-2011) and we would like to provide the research results for the establishment of recommendations or guidelines for the treatment of adult women before the menopause with regard to the impact factors on the bone mineral density and for the development of health education materials for the accurate measurement of bone mineral density of young women in order to prevent the postmenopausal osteoporosis. With respect to the general features of adult women before the menopause, the bone mineral density was higher in the entire femur at age 40-44, femoral neck at 35-39, in high-school education level, in the earlier menarche group, without smoking experiences, with regular walking time and exercise frequency and with the habits of eating no hamburger or pizza. With regard to the body composition, the bone mineral density was higher in obesity and lower in underweight cases, higher among people with abdominal obesity and weight control experiences. In terms of total body fat ratio, total amount of fat and muscle, the bone mineral density got gradually increased from the 1st quarter (Q1) to the 4th quarter(Q4). The obesity, disease, total amount of fat and muscle were shown to be significantly related with the bone mineral density in this research and it is required for young women to keep the adequate weight and the normal BMI in order to increase the bone mineral density. For the prevention of osteoporosis, it is advised to keep the right habits including regular exercise and no smoking discipline from the growing period and achieve the maximum bone mass thru the control of proper weight from a young age.

The current study examined the effects of catechin on lipid composition of serum and liver and adipocyte of epididymal fat pads in obese rats fed high fat diet. Sprague-Dawley male rats weighing $100{\pm}10g$ were randomly divided into eight groups, four normal diet groups and four high fat diet groups according to the level of dietary catechin supplement. The rats were fed ad libitum experimental diets for 4 weeks and then they were sacrificed. Body weight in HF group was heavier than that of NC group, but HFCM and HFCH groups were significantly reduced compared to HF group. Relative body weight to abdominal weight and relative body weight to epididymal weight in HF group were increased to 103% and 106%, respectively, compared to NC group, but HFCM and HFCH groups were significantly reduced as compared to HF group. The levels of serum triglyceride, total cholesterol, LDL-cholesterol and atherogenic index in HFCH groups were significantly lower than those of HF group, whereas HDL-cholesterol levels were increased. Total lipid contents of liver in HF group was significantly higher than that of NC group, but HFCH group maintained the NC level. There were no significant difference in hepatic triglyceride contents of high fat diet groups. Contents of hepatic cholesterol in HF group was 29% higher than that of NC group, but HFCM and HFCH groups were significantly reduced as compared to HF group. Cell number and cell size of epididymal fat pads in HFCM and HFCH groups were significantly reduced, respectively, compared to HF group. Improved lipid metabolism observed in rats fed catechin may be caused by an alteration of number and size in epididymal fat pad and lipid composition.

This study was conducted to analyze the effect of isoflavone intake on prevention of chronic disease in middle and old aged man. In this study we used FFQ (Food frequency questionnaire) and the isoflavone intake level of the subjects was 25.10 mg per day. We divided the subjects into three group -high, medium, low isoflavone intake level- and investigated the relation among isoflavone intake level and clinical/anthropometric characteristics. The intake of isoflavone was inversely related with the body fat in male subjects. And we also divided the subjects into 2 groups with normal and abnormal clinical/anthropometric risk factor. The isoflavone intake level of the abnormal group with high TG, high WHR and high body fat was lower than the normal group. The main food source of isoflavone was soybean curd, bean sprout, soybean paste, soybean and soy milk, and we also investigated the relation between frequency of soybean food and anthropometric and clinical variables. The frequencies of soybean curd, soybean paste, soybean broth, soy milk, bean sprouts, peanuts, soybean and dambuk as well as intake of isoflavone were inversely correlated with some anthropometric and clinical variables such as blood pressure, TG, BMI, % body fat, and waist-hip ratio, whereas positively correlated with HDL cholesterol, muscle mass and bone density. We suggest that high consumption of soy products and isoflavone is associated with decreased blood lipid and body fat in middle and old aged man and might be useful for prevention cardiovascular diseases. From this study, we obtained valuable basic information on recommended isoflavone intake level and guidelines for the prevention of some chronic diseases/health problems.

The objective of this study was to investigate the effects of nutrition education based on ubiquitous healthcare (u-health) service on changes in dietary habits, nutrition intake, and risk factors for metabolic syndrome in male workers. In total, 72 male office workers with at least three risk factors of the National Cholesterol Education Program-Adult Treatment Panel III were recruited as subjects. Anthropometric measurements and biochemical analyses were conducted on all subjects. Dietary habits and nutrient intake were determined by a questionnaire using the 24-hour dietary recall method before and after nutrition education. Subjects measured their body composition, blood pressure, and physical activity more than once per week during the 12 weeks using the u-health care equipment and sent these data to a central database system using a personal computer. Individual nutrition counseling was provided four times on the first, fourth, eight, and twelfth weeks. The results showed significant decreases in abdominal circumference, body fat (%), diastolic blood pressure, serum triglycerides, and serum total cholesterol during the 12 weeks. Subjects with more than 12 measurements showed significant reductions in abdominal circumference, body fat (%), serum triglyceride, and serum total cholesterol. Mean intake of dietary fiber, animal calcium, potassium, vitamin C, and folic acid after nutrition education were higher than those before nutrition education. Participants showed significant increases in the frequencies of consuming protein foods (meat, fish, eggs, beans, tofu, etc.) and vegetables. In conclusion, nutrition education through the u-health service resulted in positive effects on the risk factors for metabolic syndrome, nutrient intake, and dietary habits.

Purpose: This study was conducted to identify the prevalence and related factors of metabolic syndrome in Korean adolescents. Method: Based on data from the Korea National Health and Nutrition Examination Survey of 2015, 404 adolescents aged 12-18 years were enrolled. We used the adolescent Ford method as the diagnostic criteria for adolescent metabolic syndrome. The data were analyzed using descriptive statistics, t-test, $x^2$-test, and logistic regression with SPSS WINDOW 23.0 program. Results: The prevalence of metabolic syndrome in Korean adolescents was 6.5% (6.5% for boys and 6.4% for girls). Among metabolic syndrome components, the prevalence of elevated blood pressure (28.8%) was the highest, followed by elevated triglycerides (21.3%), increased waist circumference (14.1%), decreased high density lipoprotein-cholesterol (11.5%), and elevated fasting blood sugar (7.8%). The only factor associated with metabolic syndrome in both boys and girls was the Body Mass Index (BMI), and the likelihood of a metabolic syndrome increased by 1.6 to 2.3 times (Adjusted OR=1.552 to 2.313, p=0.001) as the BMI increased. Conclusion: Based on the results of this study, an intervention program should be developed and provided to maintain the BMI in the normal range for the prevention and management of metabolic syndrome in Korean adolescents.

The effects of pectin on obesity was studied using 3T3-L1 pre-adipocytes and rats fed 20% high fat diets. The concentration of leptin released from 3T3-L1 adipocytes in the presence of pectin was significantly decreased by 85% compared to that of the control (p<0.05), however, glycerol concentration was not changed. These data indicate that pectin seems to inhibit lipids accumulation in the adipocytes rather than enhance the lipolytic activity. Forty Sprague Dawley rats were fed 20% high fat diet for 8 weeks to induce obesity and then divided equally into four groups. Experimental groups were normal diet group (ND), high fat diet group (HFD), HDF with 10% pectin group (HFP10), and HDF with 20% pectin group (HFP20). Diet for the each group was prepared to be iso-caloric following AIN-76 guideline. After obesity was induced, rats were placed on an restricted diet for 9 weeks. The body weight of HFD increased 50% (p<0.05) compared to the ND, while it was decreased by 12% and 16% for HFP10 and HFP20, respectively (p<0.05). The relative amount of visceral fats for HFDl0 and HFD20 were decreased by 45% and 59% compared to that of HDF (130%), respectively (p<0.05). Pectin seems to have a greater effect on reducing visceral fats accumulation than weight reduction. Significantly increased level of triglyceride, total cholesterol or LDL-cholesterol in the plasma of HFD was returned to the normal or even below the normal by pectin diet, while the level of HDL-cholesterol increased. Lipid lowering effect was also observed in the liver and heart. These effects of pectin were dosedependent. In conclusion, the beneficial effect of pectin on the obesity was observed from cell culture experiment and animal study in terms of inhibiting the accumulation of lipids in the adipocytes.

This study evaluated the effects of Rubus coreanus Miq. oil on the plasma lipid profile of high fat diet (HFD)-induced obese mice. Animals were randomly divided into 4 groups (n=10). After completion of the 5-week experimental period, we measured bodyweight gain, food intake, adipose tissue mass, and plasma lipid profile. We also analyzed the activities of carnitine and superoxide dismutase (SOD) involved in ${\beta}$-oxidation and antioxidation, respectively. Our results show that HFD-induced weight gain in animals in the R. coreanus Miq. oil diet group (RCO) and corn oil diet group (CO) was significantly lower compared to animals in the HFD group; RCO supplementation had a more noticeable effect than CO. Visceral and back fat weights were lower in the RCO and CO groups while plasma HDL cholesterol (HDL-C) and HDL-C per total cholesterol [HDL-C/TC (%)] ratio were significantly higher in the RCO group. The contents of acid-soluble acylcarnitine and total carnitine as well as SOD activation were significantly higher in the RCO group, but no significant difference was observed between the RCO and CO groups. In conclusion, RCO effectively averted elevation of total body weight and fat weight in HFD-induced obese mice and promoted increased HDL-C. Therefore, R. coreanus Miq. oil might play an anti-obesity role in obese people and could be used as an effective oil supplement.
