The purpose of this work was to study the relationships between dietary intake and serum lipid profile in 293 adult subjects (mean age: $45.9{\pm}0.7$, men: 163, women: 130) who visited health promotion center. The anthropometric and biochemical blood indices were measured, and nutritional intakes were assessed using a food frequency questionnaire method. The subjects were divided by three groups in accordance with a standard for treating hyperlipidemia; those who had blood cholesterol levels above 240 mL/dL or triglyceride levels above 200 mL/dL were put into the risk group (Risk), while those with blood cholesterol levels below 200 mL/dL and triglyceride levels below 150 mL/dL were put into the control group (Control). Subjects who were between the two groups in terms of blood cholesterol and triglyceride levels were put into the borderline group (Borderline). Risk group showed significantly higher body mass index, body weight, waist circumference, and fat content compared to control group. The levels of calorie, carbohydrate, fat, and protein intake were significantly higher in the risk group than control group. There were significantly positive correlations between dietary calorie, carbohydrate, fat, and protein intake and blood triglyceride concentration. The blood HDL-cholesterol concentration had negative correlation with carbohydrate intake. These results suggested that overeating may be one of important factors affecting hyperlipidemia in Korean adults.

This study was conducted to investigate the effects of green tea or coffee consumption on the serum lipids profiles. This study analyzed data of 1,343 participants (753 males and 590 females) among the people who underwent medical check-up. The subjects were divided by three groups as pattern of green tea or coffee consumption. Anthropometric measurements, biochemical analysis and nutrient intake using a food frequency questionnaire were performed. There were no significant differences among groups in height, % body fat, waist circumference, and body mass index. There was no significant difference among groups in energy intake. Fat intake was significantly higher in green tea and coffee group than the control group in men subjects. The intakes of dietary Fe, vitamin A, $\beta$-carotene, and folate was the lowest in coffee group (p<0.05). The intakes of dietary fat was the highest in coffee group in male subjects (p<0.05). Serum concentrations of total cholesterol and LDL-cholesterol were green tea< control< coffee group in order by multivariate analysis after adjusting for confounding factors. The serum concentrations of total cholesterol and LDL-cholesterol were significantly lower in green tea group than coffee group by multivariate analysis after adjusting for confounding factors (p<0.05). However, there was no significant difference in the serum concentrations of total cholesterol and LDL-cholesterol between green tea and control group. These results suggest that green tea consumption didn't show positive effects in preventing hyperlipidemia but coffee consumption showed negative effects in hyperlipidemia.

This study was carried out in order to investigate the status of food and nutrient intakes depending on the types of chronic disease of the elderly at welfare centers in Seoul. The total number of subjects was 299 elderly over the age of 60 (82 men and 217 women); they were grouped by the disease status: normal, cardiovascular disease (CVD), diabetes mellitus (DM) and arthritis patients groups. The dietary intakes were obtained by a 24-hour recall and analyzed by CAN-Pro 4.0; they were then compared with the dietary reference intakes for the Korean (KDRIs). In the results of anthropometric data according to chronic disease, the waist circumference of the normal group in males and females was lower than the other groups; in particular, the normal female group showed a lower level of waist-hip ratio, body mass index (BMI) and body fat % than those of the other groups. The arthritis group showed a higher intake of milk products than the other groups (p < 0.05); consequently, calcium intake was significantly higher than that of the other groups (p < 0.001). Vitamin A intake in the arthritis group was significantly higher than the intake in the normal and DM groups (p < 0.01). Normal and arthritis groups showed significantly higher intake of zinc and copper than the CVD group (p < 0.01). In general, about 80% of the subjects in this study revealed insufficient intakes of riboflavin, vitamin C, calcium, dietary fiber, vitamin D, biotin and potassium, compared with the estimated average requirement (EAR) or adequate intake (AI). However, sodium intake of all groups was higher than the AI of KDRIs. In conclusion, nutrient intake, according to the chronic disease, showed significant difference in some of the micronutrients, vitamin A, Ca, Zn and Cu. Therefore, we suggest that dietary guidelines, such as reducing the intake of salty foods and sweet drinks and increasing the intake of foods with sufficient calcium, vitamin D and vitamin C, are necessary to the improvement of eating habits for the elderly.

Quantities as well as distributions of adipose tissue (AT) are significantly related to cardiovascular disease (CVD) risk factors and can be altered with caloric restriction. This study investigated which cross-sectional slice location of AT is most strongly correlated with changes in CVD risk factors after caloric restriction in obese Korean women. Thirty-three obese pre-menopausal Korean women ($32.4{\pm}8.5$ yrs, BMI $27.1{\pm}2.3\;kg/m^2$) participated in a 12 weeks caloric restriction program. Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) were measured using computed tomography (CT) scans at the sites of L2-L3, L3-L4, and L4-L5. Fasting serum levels of glucose, insulin, triglyceride, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), leptin and homeostasis model assessment-insulin resistance (HOMA-IR) were observed. Pearson's partial correlation coefficients were used to assess the relationship between AT measurement sites and changes in CVD risk factors after calorie restriction. When calories were reduced by 350 kcal/day for 12 weeks, body weight (-2.7%), body fat mass (-8.2%), and waist circumference (-5.8%) all decreased (P < 0.05). In addition, following caloric restriction, serum levels of glucose (-4.6%), TC (-6.2%), LDL-C (-5.3%), leptin (-17.6%) and HOMA-IR (-18.2%) decreased significantly (P < 0.05) as well. Changes in VAT at the level of L3-L4 were significantly greater than those at other abdominal sites, and these changes were correlated with changes in TC (P < 0.05), LDL-C (P < 0.001), SBP (P < 0.001) and HOMA-IR (P < 0.01). These results show that VAT at L3-L4 had a stronger correlation with CVD risk factors than with other AT measurement sites after caloric restriction.

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.

Purpose : Obesity is, along with metabolic syndrome, closely related with nonalcoholic fatty liver disease. This study tried to evaluate the prevalence of nonalcoholic liver disease in obese children and verify the factors associated with the disease. Methods : Two hundred and seventy nine children who showed a body mass index of 95 percentile over the baseline in health examinations of surrounding schools were evaluated. Questionnaires, body measurements, blood examinations, and ultrasonographic measurements of abdominal fat were examined. Results : Out of 279 children enrolled for the study, 27 children were found to possess nonalcoholic liver disease(9.7%). Among those found to be positive for nonalcoholic liver disease, it's prevalence increased to 15.2%(22 out of 144 children) among children with severe obesity. Factors known to be involved with metabolic syndrome, namely waist/hip circumference ratio and thickness of abdominal fat, were found to be closely related to nonalcoholic fatty liver as well. Conclusion : The prevalence of nonalcoholic fatty liver in obese children was 9.7%, with higher incidence observable in severer obesity. Factors responsible for metabolic syndrome were closely associated with nonalcoholic fatty liver disease, and the level of insulin resistance, which is an useful index in both diseases, can be utilized in evaluation of the effect of treatment and control of risk factors.

The purpose of this study was to compare Obesity Age (OA) and chronological age, to calculate Obesity Age (OA), which gauges the state of obesity, and to analyze presented factors of obesity using expectant factors on middle-aged obese women. The subjects were one hundred twenty seven middle-aged obese women ($49.6\pm7.3$ yr, BMI $29.41\pm2.9$, fat $36.8\pm4.6%$) who participated in different weight loss programs three times. The body composition, physical fitness, blood pressure and blood were measured before the weight loss programs. Informed consent was obtained from all subjects before enrollment in the study. The regression equation is as follows: (1) OAS (Obesity Age Score)=$0.106*X_1+0.035*X_2+0.048*X_3+0.041*X_4+0.003*X_5-0.037*X_6-10.667$ ($X_1$: BMI, $X_2$: weight, $X_3$: %fat, $X_4$: WC, $X_5$: TG, $X_6$: $VO_{2max}$), (2) OA (Obesity Age)=7.3*OAS+49.6*(-1), (3) Z (correction factor)=(CA-49.6)(1-0.03), (4) OAc (corrected Obesity Age)=1.03*CA-7.3*OAS+1.47. The comparison of corrected Obesity Age (OAc) and chronological age did not have any differences, and the average of the OAc was close to chronological age. The correlation coefficient between the OAc and chronological age was r=0.724 (p<0.05). The equation can be utilized for middle-aged obese women, because it could evaluate the obesity-related factors by including BMI, body weight, %fat, waist circumference, triglycerides and $VO_{2max}$.

This study was carried out to investigate the nutrients intakes of hypertensive female farmers in Korea. The number of subjects in this survey was 40(normal 22, hypertensive 18). Body weight, height, circumferences of waist, hip and thigh, and systolic and diastolic blood pressure of them were measured, and lipids and mineral levels of venous blood, mineral contents of 24-hour urine and Na or K levels of some sodium sources were analyzed. The evaluation of nutritional status was performed by recording dietary intake for a day and analyzing it with food composition table. Body weight, waist circumference, waist to thigh ratio, and serum triglyceride were higher in hypertensive. The mean values of calcium, vitamin B2 and niacin intakes of the subjects didn't meet the Korean recommended allowances though there was no significant difference in nutrients intake between two groups. The value of sodium intake presumed from content of sodium excreted to urine, and Na content and Na/K in Korean cabbage Kimchi was higher in hypertensive. These results suggest that reducing of serum triglyceride, decreasing of sodium intake and changing the taste for saltiness can help develop the health status of the rural female hypertensive and control the blood pressure of them.

HbA1c was recently adopted as a reliable indicator for screening diabetes. This study investigated the ability of nutrition consultation to prevent diabetes in overweight women (BMI 23 $kg/m^2$ or more) using HbA1c as an indicator. Twenty overweight and obese women (with $HbA1c{\geq}5.7$%) completed the 12-week nutritional study, with individual and personalized nutrition counseling performed every 2 weeks. The main study guidelines involved the following: 1) reducing the intake of high fat foods and alcohol, 2) consuming a large amount of vegetables, 3) reducing the intake of simple sugars and empty-calorie foods, and 4) increasing physical activity to ${\geq}30$ min/day. Anthropometric (height, weight, BMI, body muscle (kg), body fat (%), waist and hip circumference, blood pressure) and biochemical parameters (fasting blood sugar (FBS), HbA1c, lipid profiles, hs-CRP) were measured before and after the nutrition consultation. After 12 weeks, the HbA1c<5.7% group had significant decreases in BMI, WC, HC, WHR, HbA1c, hs-CRP and also dietary intake of energy (P<0.01), carbohydrates, lipids (P<0.01), proteins (P<0.01) and cholesterol was significantly decreased (P<0.05). In the HbA1c ${\geq}5.7$% group, HbA1c, TC, LDL, NON-HDL, hs-CRP and dietary intake of energy, carbohydrate, lipid, protein, and cholesterol significantly decreased (P<0.05). These results suggest that nutrition consultation effectively helps to prevent diabetes in overweight and obese women after applying HbA1c standards. Overall, the improvement in all markers measured suggest that HbA1c is a good indicator for blood glucose regulation, helping to prevent diabetes.

1. Objectives: The purpose of this study was to analyze the physical and psychological characteristics of each Sasang type groups which were classified by Sasang medicine specialist. 2. Methods: The subjects were 115 (85.2% of male) university students with $26.8\pm5.4$ yrs. of age and $12.9\pm1.7$ yrs. of education. We can get 30 of Soyang type, 39 of Taeeum type, 46 of Soeum type after the Sasang type classification. Their physical characteristics were measured with Bioelectrical Impedance Analysis (Inbody 720, Biospace, Seoul), and psychological characteristics with Temperament and Character Inventory (Maumsarang, Seoul). The general linear model (SPSS 12.0, SPSS Inc, Chicago) were used for the analysis with gender and age as covariance. 3. Results and Conclusions: Taeeum type group ($75.64\pm13.01$, $26.12\pm4.16$, $15.74\pm2.42$, $11.30\pm1.80$, $3.93\pm0.62$, $18.43\pm7.70$) showed significantly bigger weight, intra-cellular water, extra-cellular water, protein, mineral, body fat mass than Soeum type group ($61.32\pm8.56$, $22.54\pm3.87$, $13.70\pm2.15$, $9.74\pm1.68$, $3.35\pm0.51$, $10.79\pm3.97$). In obesity degree such as Body Mass Index and Waist-hip ratio, and circumference measures in chest, waist and hip, we found significant differences in the order of Taeeum>Soyang>Soeum. As a psychological perspectives Soyang type group ($41.90\pm13.32$) has higher NS (Novelty-Seeking) score than Soeum type group ($35.22\pm11.22$) with marginal significance (p=0.052). In sub-scale measurements Soeum type group ($10.61\pm3.69$) has significantly lower value than other two groups in P3 (Ambition). The results of present study showed that Taeeum type by specialist has same physical characteristics as previously reported QSCC II based studies. Temperament profile of each Sasang type group will serve as an important evidence for further study showing that the Sasang typology has biological basis.
