The purpose of this study was to evaluate the usefulness of variables which were known to be related to blood pressure for discriminating between hypertensive and normotensive groups. Variables were obesity, serum lipids, life style-related variables such as smoking, alcohol, exercise, and stress, and demographic variables such as age, economical status, and education. The data were collected from 400 male clients who visited one university hospital located in Incheon, Republic of Korea, from May 1996 to December 1996 for a regular physical examination. Variables which showed significance for discriminating systolic blood pressure in this study were age, serum lipids, education, HDL, exercise, total cholesterol, body fat percent, alcohol, stress, and smoking(in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-systolic pressure group was 2%, predicting a normal-systolic pressure group was 70.3%, and total Hit Ratio was 70%. Variables which showed significance for discriminating diastolic blood pressure were exercise, triglyceride, alcohol, smoking, economical status, age, and BMI (in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-diastolic pressure group was 71.2%, predicting a normal-diastolic pressure group was 71.3%, and total Hit Ratio was 71.3%. Multiple regression analysis was performed to examine the association of systolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the systolic blood pressure was statistically significant (p=.000) and adjusted $R^2$was 0.09. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.11 (p=.000) : therefore, the contribution rate of obesity on the systolic blood pressure was 2.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising adjusted R2 to 0.12(P=.000) : therefore, the contribution rate of serum lipid on the systolic pressure was 1.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$to 0.18(p=.000) ; therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 6.0%. Multiple regression analysis was also performed to examine the association of diastolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the diastolic blood pressure was statistically significant (p=.01) and adjusted $R^2$was 0.03. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.06 (p=.000) ; therefore, the contribution rate of obesity on the diastolic blood pressure was 3.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising the adjusted $R^2$ to 0.09(p=.000) ; therefore, the contribution rate of serum lipid on the diastolic pressure was 3.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$ to 0.12 (p=.000) : therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 3.0%.

Purpose: The aims of this study were to identify prevalence and identify factors related to sarcopenic obesity among community-dwelling elderly women. Methods: This is a secondary analysis of the prospective cohort study. Our analysis included 338 elderly women (${\geq}65$ years old) in South Korea as a part of the Community-dwelling Older Adult Health Cohort (COHC) Study (2014-2015). Sarcopenic obesity was defined as the Asian Working Group of Sarcopenia recommendations and upper two quintiles for percentage body fat. Logistic regression analysis was used to determine the factors related to sarcopenic obesity including chronic diseases, medications, stress, fatigue, depression, exercise, level of proteins on body compositions, smoking, and alcohol use. Results: The prevalence of sarcopenic obesity was 6.2%. A lower protein on body compositions (OR 0.017, 95% CI 0.003-0.081, p< .001), a larger number of medications (OR 2.104, 95% CI 1.404-3.152, p< .001), and a higher level of fatigue (OR 1.255, 95% CI 1.023-1.541, p= .030) were related factors of sarcopenic obesity. Conclusion: The findings suggest that nutritional interventions focusing on protein intakes should be needed to prevent sarcopenic obesity among the elderly women. Polypharmacy issue for preventing adverse outcomes and level of fatigue as indicator for early identification are also considered to develop community prevention programs.

The objective of this study is to improve the health related quality of life through the efficient weight reduction by analyzing the ecological factors related to completion of weight reduction program in the obese premenopausal women aged 20-29 years. The factors influencing completion of obesity management programs in the obese women were the preferences of sweet and salt taste, health related quality of life (general health, role emotional), eating attitude scores, and regularity of mealtime scores. The finding that the completion of obese management programme were improved if the health-related quality of life was high and the physiological status related symptoms of stress, depress, and eating disorder were good has implications for the treatment of obesity. The questionnaire used this study can be available to develop the obesity assessment sheets which is required the exploration of the characteristics of obese women and the tailored multi-disciplinary obesity management program. Moreover, the obesity assessment sheets will make a contribution to determine types of the programs that is suitable for obesity women before starting an obesity management program.

Objectives: The purpose of this study was to discuss the overall and oral health conditions that affect obesity in middle-aged women in Jeju and to help them operate the effective obesity program in the future. Methods: Participants of this study were 171 middle-aged women living in Seogwipo City, Jeju Special Self - Governing Province. Data were collected through the convenience sampling method. Body mass index and waist circumference of each participant were measured, and a self-report questionnaire was applied. Results: The overall health status of obesity comprised depression, stress, diabetes, and menopause. The oral health conditions affecting obesity were bad breath and chewing. Hypertension was the main factor affecting body mass index and depression was the main factor influencing waist circumference. Obesity was more influenced by overall health status factors than by oral health status factors. Conclusions: The results of this study are expected to be useful as basic data for efficient health care services in the prevention of obesity.

The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

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.

Purpose: The purpose of this study was to identify the effects of a school-based obesity control program based on behavior modification and self-efficacy for obese elementary school children. The program was composed of strategies to modify diet and exercise habits and to increase self-efficacy. Method: The subjects were 57 obese children (experimental group = 28, control group = 29) whose Rohler index was 150 and over. The program was implemented once a week for 12 weeks from September 16 to December 12, 2003. The data was analyzed by Fisher's exact probability, $x^2$-test, t-test, and Wilcoxon Rank Sum test. Result: The Rohler index, fat mass and lean body mass of the experimental group positively changed after the intervention more than those of the control group, but there was a significant difference in the Rohler index only (t=2.06, p=.045). In addition, obesity stress significantly decreased (z=-2.86, p=.047) and dietary self-efficacy significantly increased (t=2.35, p=.023) in the experimental group than those of the control group. Conclusion: This study supports that a school-based obesity control program based on behavior modification and self-efficacy can be effective in decreasing obesity stress and increasing dietary self-efficacy. Parents, school nurses and the other support groups should be encouraged to participate from the planning stage of the program to be effective in weight control of obese elementary school children. Also school-based program should be implemented as an essential course in the curriculum, not as an elective.

The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y$\alpha$-tocopherol, $\beta$-carotene and ascorbic acid did not show their significant correlations with TAS. These results showed that the hypertensive elderly are prone to be obese and to have increased TAS. Due to unknown factors affecting TAS values, measurement of plasma TAS as a sole indicator of total antioxidant capacity is limited to fully understanding changes in the body's free radical trapping power. However, the results from the current study may suggest that hypertension and/or obesity might increase oxidative stress, followed by increased the body's total antioxidant defense system.

Purpose: The purpose of this study is to find out the relations between the index of obesity by body composition analysis (EMI. %BF and WHR) and results of other oriental health examinations (QSCC II, HRV and APG) on some women. Methods: 114 women who were tested by oriental health examination between May 2006 and August 2008 were studied. Results: As a result of the study on the relations between the index of obesity by body composition analysis and sasang constitution, it was found that each of them had significant differences among themselves and Taeumin had the highest significance than other sasang constitution. As a result of the study on the relations between the index of obesity by body composition analysis and HRV, it was discovered that there was no significant relationship between BMI and WHR and HRV. However, %BF had negative correlations with autonomic activity, stress resistance and stress index. As a result of the study on the relations between the index of obesity by body composition analysis and APG, it was found that they had positive correlations with each other. Conclusion: In conclusion, there are significant relations between the index of obesity by body composition analysis and results of other oriental health examinations.

Objectives: The objective of this study was to identify factors associated with adolescent obesity, as well as any new factors that correlated with a change in the rate of obesity over time. Methods: The study used 5-yearly data collected by the Korea Youth Risk Behavior Survey starting from the year 2006 up until 2021 (data from 2nd, 7th, 11th, and 17th surveys were analyzed). Factors such as demographics, dietary factors, health behavioral factors, and mental health factors were studied. All data were analyzed using IBM SPSS 27.0, employing chi-square tests and multiple logistic regression analysis. Results: This study included data from a total of 255,200 participants. Factors contributing to obesity varied with time. Over the survey duration of 15 years, low academic achievement, parents with low levels of education, low frequency of fruit consumption, low frequency of fast food intake, long periods of being seated, and high levels of stress were significantly associated with a high rate of obesity. Factors that showed a new correlation with an increase in obesity rates included living with single parents, low frequency of muscle strengthening exercises, and experiencing intense sadness and despair in the past year. Factors that were correlated with a change in obesity rates over time included household economic status, frequency of carbonated beverage consumption, frequency of intense physical activity, and frequency of alcohol consumption. Breakfast intake and smoking were not significantly associated with obesity rates in the 15-year period. Conclusions: While several factors associated with obesity remained consistent over time, several new factors have emerged in response to social, economic, and environmental changes contributed to a change in obesity rate over time. Therefore, to prevent and manage adolescent obesity, continuous research into the new emergent factors contributing to obesity is needed.
