심혈관계질환의 예방과 영양교육의 기초자료를 제공하기 위하여 성인 남녀를 대상으로 규칙적인 운동 습관과 음주, 흡연, 폐경, 비만 여부에 따라 신체계측치와 콜레스테롤, 중성지방, LDL-cholesterol, LDL-cholesterol 등의 혈청지질 및 영양소 섭취량을 비교 조사한 결과는 다음과 같다. 1)체중이나 신장, 비만 정도 및 WHR 등 신체계측지수는 음주나 흡연 여부에 따른 차이가 없었으나, 혈청 중성지방 농도를 유의적으로 상승시켰다. 2)음주군은 비음주군에 비하여 단백질의 열량비율(% RDA)이 유의적으로 높았으며(p<0.05), 흡연군은 비타민 A와 나이아신, 비타민 B6, 엽산, 비타민 C, 비타민 E의 섭취량에 있어서 비흡연자들보다 낮은 경향을 보였다. 3)운동에 의한 혈청지질 농도에는 뚜렷한 차이가 없었으나, 남성들의 경우 현재의 체중과 PIBW, Quetlet index, 엉덩이둘레가 비운동자들보다 많은 것으로 나타났다. 영양소 섭취량에 있어서 남성의 경우 운동군이 비운동군에 비해 콜레스테롤과 나이아신 및 인을 더 섭취하고 있었으며, 당질의 섭취비율은 유의적으로 더 낮았다(p<0.05). 여성의 경우에는 불포화지방에 유의적 차이를 보여 비운동군의 불포화지방 섭취량이 더 많았다(p<0.05). 4)폐경한 여성의 경우 폐경 전 여성에 비하여 신장은 더 작고 WHR은 더 높았다. 폐경 이후 estrogen 분비의 변화로 인하여 혈중 지질 성분 중에서는 cholesterol이 198.4$\pm$36.3mg/dl, LDL이 119.5$\pm$34.9mg/dl로 폐경 전의 수치보다 유의적으로 높았다(p<0.01). 5)비만 여부는 남자의 경우 콜레스테롤 농도에(p<0.01)), 여자의 경우 중성지방 농도(p<0.01)에 대해 의미있는 설명력을 보이는 변수로 작용하고 있었다. 그러나 식이 섭취상태와의 관련성은 나타나지 않았다. 이상에서 생활습관이 신체계측치 및 혈중 지질 농도와 일부 상관을 보이는 것을 알 수 있었으며, 건강위험 요인도 관찰할 수 있었다. 고지혈증은 심혈관계질환의 주요한 위험 인자로 알려져 있으며, 그 유발 요인에는 여러 환경적인 요인과 식이 요인이 있다. 또한 생활습관은 영양소의 섭취량에도 영향을준다. 이처럼 식이 요인과 생활습관은 단독 혹은 상호 영향을 주게 되므로 고지혈증 및 심혈관계질환을 개선하려면 식사요법과 생활습관 교정을 병행하여야 한다. 고지혈증의 원인 중의 하나로 지적되고 있는 음주와 흡연은 상호 유도작용이 있으므로 금연이나 절주를 하고자 할 경우 두가지를 동시에 자제해야 효과적일 것으로 생각된다. 폐경후 여성들에게 발생 빈도가 높은 심혈관질환의 위험요인인 고지혈증을 예방하고자 하는 노력은 폐경후 여성들의 삶의 질적 향상을 위해서도 매우 중요하다. 또한 균형식 섭취와 운동을 통해 혈중 지질 수준을 건강하게 유지하고, 비만으로의 이행을 방지함으로써 심혈관계질환을 예방하도록 하여야겠다.

Objective: This study evaluated the effects of a non-face-to-face obesity management program, implemented during the pandemic. Methods: The non-face-to-face obesity management program used the Intervention mapping protocol (IMP). The program was put into effect over the course of eight weeks, from September 14 to November 13, 2020 in 48 overweight and obese adults, who applied to participate through the Daegu Citizen Health Support Center. Results: IMP was first a needs assessment was conducted; second, goal setting for behavior change was established; third, evidence-based selection of arbitration method and performance strategy was performed; fourth, program design and validation; fifth, the program was run; and sixth, the results were evaluated. The average weight after participation in the program was reduced by 1.2kg, average WC decreased by 3cm, and average BMI decreased by 0.8kg/m² (p<0.05). The results of the health behavior survey showed a positive improvement in lifestyle factors, including average daily intake calories, fruit intake, and time spent in walking exercise before and after participation in the program. A statistically significant difference was seen (p<0.05). The satisfaction level for program process evaluation was high, at 4.57±0.63 point. Conclusion: The non-face-to-face obesity management program was useful for obesity management for adults in communities, as it enables individual counseling by experts and active participation through self-body measurement and recording without restriction by time and place. However, the program had some restrictions on participation that may relate to the age of the subject, such as skill and comfort in using a mobile app.

Purpose: The purpose of our study is to provide useful information for me-asurement methods of childhood obesity and to provide clinical significance of bioelectrical impedance analysis. Methods: We measured height, weight, waist to hip ratio, skinfold thickness and bioelectrical impedance from 206 elementary students in Kwangju from May to July 1997. Results: In males; 1) There were statistically high correlations between tri-ceps skinfold thickness and body mass index (BMI), percentage of body fat (%BF), weight, Rohler index (RI), total fat weight (TFW), waist to hip (W/H) ratio, height, lean body mass (LBM) (all, p<0.001). 2) There were statistically high correlations between subscapular skinfold thickness and BMI, RI, weig-ht, %BF, TBW (all, p<0.001). 3) There were statistically high correlations between %BF and BMI, triceps skinfold thickness, RI, TFW, subscapular skinfold thickness, weight (all, p<0.001). In females; 4) There were statistically high correlations between triceps skinfold thickness and BMI, weight, LBM, height, %BF (all, p<0.001). 5) There were statistically significant correlations between subscapular skinfold thickness and BMI, weight, LBM, RI, height. 6) There were statistically high correlations between percentage of body fat and BMI, RI, triceps skinfold thickness. The percentage of body fat according to the bioelectrical impedance analysis highly correlated with that calculated by skinfold thickness in males (r＝0.57, p<0.01) and in females (r＝0.30, p<0.01). Conclusion: The results of our study suggests that bioelectrical impedance analysis is a useful method of estimating body fat in the childhood obesity.

This study was conducted to evaluate the effects of an abdominal obesity management program on dietary intake, stress index, and waist to hip ratio (WHR) in abdominally obese women. The subjects were 195 adult abdominally obese women (WHR ${\geq}$ 0.80) who had been participating in a nutrition education (total of nine times) and dietary habits and life style modification programs (total of six times) for 12 weeks. The abdominal obesity management program focused on the nutrition provided by breakfast, lunch, and dinner, proper dietary habits, and practices to improve life style. The subjects were divided into a WHR decrease group and a WHR increase group according to changes in the WHR. Daily nutrient intake was assessed with a 3-day food record, body measurements and blood vessel age, stress index, and a health index that were measured at baseline and after 12 weeks. After the intervention, weight, waist circumference, hip circumference, WHR, and body mass index (BMI) decreased significantly in the WHR decrease group. Energy intake increased from 1486.2 kcal to 1541.4 kcal with a significant improvement in nutrient density for animal protein, total fat, animal fat, fiber, calcium, phosphorus, zinc, vitamin $B_6$, vitamin C, vitamin E, and saturated fatty acids in the WHR decrease group. Additionally, dietary diversity increased significantly in the WHR decrease group compared to that in the WHR increase group. The WHR decrease group showed a significant improvement in the stress and health indices. Changes in WHR were correlated with changes in nutrient intake (animal protein, total fat, animal fat, plant fat, fiber, calcium, iron, potassium, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, and folate) and medical index profiles (stress and indices) adjusted for age, birth status, baseline BMI, and baseline WHR. These results show that an abdominal obesity management program was effective not only for reducing the WHR but also to improve dietary intake and the stress index in abdominally obese women.

To figure out the causes of obesity against middle-aged women, this study aimed to provide basic data for setting an obesity-related policy through analysis on diverse related factors. Against the healthy middle-aged women who visited 'N' Hospital Health Center in Incheon from April to November 2014, anthropometric assessment, body composition test and abdominal fat distribution test were conducted using Fat-CT. They were carried out against 159 women who agreed with the purpose of the study, using BMD, Q-CT. According to Fat-CT, subcutaneous and visceral types accounted for 39% (76 women) and 61% (119 respondents) respectively. In terms of BMI, 'underweight ($18.5kg/m^2$)' and 'overweight ($25kg/m^2$ or above)' were 13 women (6.7%) and 60 women (30.8%) each with the average of $23.5{\pm}4.11kg/m^2$. Mean while, waist circumference, diastolic blood pressure, systolic blood pressure and neutral fat were statistically significant at the 5% significance level. As getting older, muscle weakness offsets increase in body weight with abdominal obesity. A group with low BMI should also be considered due to increase in waist circumference.

Purpose : Chronic kidney disease (CKD) and obesity are the worldwide public health problem. Obesity is an already well-established risk factor for CKD. The objective of this study is to evaluate the relationship between high BMI and increased risk for nephropathy by clinical data. Methods : Study group were 26 patients who had $BMI{\geq}25\;kg/m^2$ and control group were 49 patients with BMI<$25\;kg/m^2$. Both groups received renal biopsy in Kyung Hee Medical Center between 2003. Jan.-2007. Dec. BMI was calculated from measured weight and height when they were admitted to the hospital. We collected laboratory data such as CBC and blood chemistry. Results : Our hypothesis was that overweight and obesity are associated with incidence and progression of CKD. From kidney biopsy, we found IgAN 17, MesPGN 5, HSPN 2, Intestitial nephritis 1, IgMN 1 (total 26) in the study group whereas IgAN 22, MesPGN 17, HSPN 3, MGN 3, benign hematuria 2, MPGN 1, Intestitial nephritis 1, (total 49) were found in the control group. There was no significant difference between the two groups. Overweight patients demonstrated significantly higher platelet, TG, ALT, and uric acid level compared to control group. Conclusion : We identified a significant relationship between overweight and development of CKD. These results suggest that overweight children have an increased risk for CKD than those who are not obese. So, we should pay attention to children with overweight who have CKD and earlier weight management is crucial to prevent aggravation of CKD.

This study was about the relation of 129 differently stressed male college students's on or off-line contact behavior to out-eating places. We researched the subjects's obesity degree such as body fat percentage, body mass index, stress condition, and contact behavior to out-eating places. Subjects's average age was 20, height 174.9cm. More stress they felt, heavier their body weight was and more obese. 37.1% of Strongly stressed group, 28.8% of medium and 25% of normal stressed group felt severe depression. As the result of pearson correlation, stress condition was positively related with body weight, obese degree, body mass index(BMI) and exercise time. Body weight was positively related with obeses degree, BMI, and the amount of smoking and drinks. Strongly stressed group used more internet to search the information about out-eating places, they had more experience to search the homepage of out-eating places than other groups significantly. Strongly stressed group cared more about the sanity of out-eating places where they ate. and they were interested in various experiences than other groups. Strongly stressed group felt the tasty was the most important satisfying factor significantly and visited the out-eating place that satisfied them again than other groups.

Purpose : Body composition is important to define and manage obesity and undernutrition. Obesity is a significant health problem with medical and psychological consequences for children and adolescents. Body composition analysis (BIA) is a simple, rapid, noninvasive, and reproducible technique. However, comparative analysis of body composition has not been done in young children below 7 years old. The aim of this study is to estimate antropometric data and body composition by BIA, and to investigate the correlation between anthropometric data and fat mass or fat percent in young children. Methods : We measured height, weight, body mass index (BMI), fat mass, and fat percent by BIA in 1,376 children aged 3-6 years of whom 688 were males and 688 were females. Results : Fat mass, fat percent, intracellular fluid, extracellular fluid, protein, and minerals were significantly higher in the obese group. A significant positive correlation exists between fat mass and BMI or weight. A significant positive linear correlation was also noted between fat percent and BMI. Protein, weight, fat mass, and fat percent were significantly different among groups. Conclusion : BIA is an objective, accurate method to estimate body fat in childhood obesity cases. Fat mass and fat percent data acquired by using BIA highly correlated with BMI. However, a large-scale study is needed to diagnose obesity in young children.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.

Obesity is the risk factor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.
