This study was intended to provide basic data of nutrition education to a prevention of obesity and living patterns of elementary school students. Through the measurment of the actual obesity rate of children for students who were in the fifth and sixth grades of elementary school as well as their mothers, and by analyzing obesity-related factors. Children have started to have the characteristics obesity and obesity problems. 1. There were total 234 children including 133 boys (56.8％) and 101 girls (43.2％) for the study. There were 80 children in the fifth grade (34.2％) and 154 children in the sixth grade (65.8％). 2. Among the subjects 20.1％ were obese. By gender, the obesity rate of boys (27.1％) was higher than that of girls (l0.9％)(p＜0.01). By grade, children in the fifth grade (26.3％) had higher obesity rate than children in the sixth grade (l6.9％)(p＜0.05). 3. In terms of the educational level of parents, the obesity rate of children of parents who received university and／or higher education was 27.5％ (p＜0.05). 44.1％ of parents answered ‘I almost never give snack’s’(p＜0.01). 4. There was 32.8％ for an irregular quantity of meal. There was no obese child who under-ate (p＜0.05). In terms of impulse eating, ‘I eat.’ and ‘I don't eat.’ were 24.4％ and 25.9％ respectively. The obesity rate of the case of ‘I eat only food I like.’ was 10.6％ (p＜0.05). In terms of the obesity rate based on the daily average meal frequency, there was the highest rate of 26.1％ for I average meal frequency per day, 13.0％ for 2 daily average meal frequency, and 7.4％ for over 3 average meal frequency per day (p＜0.05). For a degree of a physical activity, the group of active physical activity (p＜0.05) and the group which liked the physical exercise showed a lower obesity rate (p＜0.001). The obesity rate of children who had regular exercise was 11.8％. It was lower than the obesity rate (24.8％) of children who didn't exercise (p＜0.01). The higher exercise frequency per week was, the lower the obesity rate was(p＜0.01). In terms of the exercise time, there was 8.3％ for over 60 minutes and 28.9％ for less 15 minutes. The group which had the long exercise time showed a lower obesity rate(p＜0.05). As the result, the education for obesity must enable students to recognize the warning signs for obesity and control their own weight with proper living patterns, by modifying behaviors considering the degree of obesity. Obesity must be controlled by the prevention and education connected with the family for all students as one of the school health programs. There must be also the development of a program through individual consultation considering the degree of obesity.

A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8kg of average weight loss was accomplished using a following program ; low calorie diet(1200kcal/day with all essential nutrients), low impact aerobic exercise(50~60% of $VO_{2max}$, 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional conseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and comparied with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

Purpose: This study is aimed at testing the effect of health promotion program on health promoting behavior and cardiovascular risk factors of middle-aged women. Method: The research design was the nonequivalent control group pre-post test. Twelve middle-aged women were the experimental group and ten were the control group. The 8-week health promotion program was given to the experimental group. There were health promotion theories, flexibility and muscle strength exercise, cardiopulmonary endurance exercise, nutrition, stress management, cancer prevention and early detection, management of menopause and wrap-up in health promotion program for middle-aged women. The measurement tool was Health Promoting Behavior developed by researcher using serum cholesterol, obesity rate, systolic blood pressure, and diastolic blood pressure as cardiovascular risk factors. Result: The experimental group showed a higher score of health promoting behavior than the control group. There were no differences on cardiovascular risk factors(cholesterol, obesity rate, diastolic blood pressure) between the experimental and control groups except systolic blood pressure. Conclusion: Conclusively, this health promotion program for middle-aged women was effective in increasing health promotion behaviors, but wasn't effective in decreasing cardiovascular risk factors except the systolic blood pressure. It seems it's necessary to re-study this using more samples and a longer duration of the program, and smaller mortality rate.

Purpose: The purpose of this study was to identify the effects of an overweight control exercise program on body composition and blood lipids. Method: This comparative study was conducted at an elementary school in Seoul, Korea. Pre and post body weight, BMI, PBF, and obesity degree as body composition and TC, HDL-C, LDL-C, and TG as blood lipids were tested. The aerobic exercise lasted 12 weeks from April to July, 2006. A total of 168 overweight 3rd grade to 5th grade school children attended and were divided into a walking exercise group (n=68) and a rope jumping exercise group (n=38). Data were analysed using SAS 8.12. Result: At the end of the program, the participation rate was higher in the rope jumping exercise group than in the walking exercise group. Body weight, BMI, PBF, obesity degree, TC, and LDL-C were lower than those before the program, and HDL-C was higher than before the program. Conclusion: The school-based overweight control exercise program was effective. Because of the participation rate was higher in the rope jumping exercise group than in the walking exercise group, rope jumping exercise is recommended for low grade children.

Purpose: This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue and pregnancy stress, blood pressure, and neonatal birth weight, using Cox's interaction model of client health behavior for overweight and obese women. Methods: This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52 patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study; they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women's hospital in J province. The lifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, and professional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017. Results: This study showed differences in the appropriate weight gain rate (χ²=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, p=.012), and an increase in pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birth weight (p>.05) were found. Conclusion: The study findings indicate that this program could be an effective intervention for the control of appropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox's interaction model of client health behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.

The purpose of this study was to investigate anti-obesity and anti-hyperlipidemic effects of extracts from Geranium thunbergii (GT) in high-fat-diet-induced obese rats. Animals were randomly divided into four groups [normal diet, high fat diet, MeOH extract of GT (GTM), and BuOH fraction of GT (GTB)] and GT samples were treated with dose of 100 mg/kg for 8 weeks. It was observed that GTB-treated group significantly reduced body weight gain, food intake, epididymal fat weight, and triglyceride level in serum and liver compared to control group. The rats fed GTB also decreased contents of thiobarbituric acid-reactive substances (TBARS), hydroxyl radical, and xanthin oxidase (XO) increased by high fat diet. Furthermore, the anti-oxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase were increased by GTB treatment. The experimental results indicate that GTB has anti-obesity and anti-hyperlipidemic effects, as well as radical scavenging activity.

Objectives: The objective of this study was to assess the safety of 'Gamitaeeumjowee-tang' by analyzing adverse events in weight loss program in combination with 'Gamitaeeumjowee-tang' and low-calorie diet. Methods: A retrospective review of adverse events in weight loss program in combination with 'Gamitaeeumjowee-tang' and low-calorie diet from the electronic medical chart (n=124) between June 2015 and December 2016 was conducted. Three Korean Medicine Doctors (KMDs) reviewed adverse events for two times, during week 2 to 4 and at week 10, after starting weight loss program. Adverse events were evaluated in terms of causality, severity and system-organ classes. Also, agreement among the three KMDs was made through further discussion in case of disagreement after independent review. Results: The overall rate of adverse events was 37.1% during week 2 to 4 and 16.9% at week 10. For causality of adverse events using the World Health Organization-Uppsala Monitoring Centre causality categories, 52.2% were evaluated 'possible' at week 2-4 and 57.1% were evaluated 'unlikely' at week 10. All symptoms were evaluated as 'mild' by LDS scale. Nausea (15, 12.1%) was the most frequent adverse event at week 2-4 and dizziness (6, 4.8%) was the most common at week 10. Conclusions: Adverse events decreased over time. There were no serious adverse events and none of the subjects were dropped due to adverse events. Continuous study is needed to prove the safety of 'Gamitaeeumjowee-tang' for treating obesity.

Purpose: The purpose of this study was to develop a system dynamics model for adolescent obesity in Korea that could be used for obesity policy analysis. Methods: On the basis of the casual loop diagram, a model was developed by converting to stock and flow diagram. The Vensim DSS 5.0 program was used in the model development. We simulated method of moments to the calibration of this model with data from The Korea Youth Risk Behavior Web-based Survey 2005 to 2013. We ran the scenario simulation. Results: This model can be used to understand the current adolescent obesity rate, predict the future obesity rate, and be utilized as a tool for controlling the risk factors. The results of the model simulation match well with the data. It was identified that a proper model, able to predict obesity probability, was established. Conclusion: These results of stock and flow diagram modeling in adolescent obesity can be helpful in development of obesity by policy planners and other stakeholders to better anticipate the multiple effects of interventions in both the short and the long term. In the future we suggest the development of an expanded model based on this adolescent obesity model.

Objectives: Obesity is regarded as one of the most prominent health threats worldwide and a serious risk factor for non-communicable diseases, such as diabetes mellitus type 2, high blood pressure, cardiovascular diseases, and some types of cancer. Given the role that societal development-as reflected by the Human Development Index (HDI)-may play in the prevalence of obesity and overweight, this study aimed to investigate the degree to which the prevalence of obesity and overweight is affected by HDI and its components. Methods: In this ecological study, the required data on HDI and its components were gathered from the latest report of the United Nations Development Program, and data on obesity and overweight were acquired from the latest reports published on the World Health Organization website. Statistical analyses were conducted using SPSS version 24.0. Results: The prevalence of obesity was determined to be significantly higher among females than males, and the gross national index per capita was found to be significantly higher for males than females (p<0.05). Significant positive correlations were found between HDI and its components and sex, as well as indices of obesity and overweight. Conclusions: A significant positive correlation exists between HDI and obesity. As policy-makers attempt to improve the general welfare of the people, they should be aware of potential unwanted effects of development on the risk of obesity and overweight among the population.

Heart rate recovery (HRR) is simply an indicator of autonomic balance and is a useful physiological indicator to predict cardiovascular morbidity and mortality. The purpose of this study was to compare the differences in HRR between metabolically healthy obesity group and metabolically unhealthy obesity and to ascertain whether heart rate recovery is a predictor of metabolic syndrome. Metabolic syndrome was defined according to the standards of the National Cholesterol Education Program Adult Care Panel III. Obesity was assessed according to WHO Asian criteria. It was classified into three groups of metabolically healthy non-obesity group (MHNO, n=113), metabolically healthy obesity group (MHO, n=66), metabolically unhealthy obesity (MUO, n=18). Exercise test was performed with Bruce protocol using a treadmill instrument. There was no difference in HRR between MHO and MUO ($32.71{\pm}12.25$ vs $25.53{\pm}8.13$), but there was late HRR in MUO than MHNO ($25.53{\pm}8.13$ vs $34.51{\pm}11.80$). HRR in obese was significantly correlated with BMI (r=-0.342, P=0.004), waist circumference (r=-0.246, P=0.043), triglyceride (r=-0.350, P=0.003), HbA1c (r=-0.315, P=0.009), insulin (r=-0.290, P=0.017) and uric acid (r=-0.303, P=0.012). HRR showed a lower prevalence of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterol in the third tertile than in the first tertile. In conclusion, MHO had no difference in vagal activity compared with MHNO, but MUO had low vagal activity. HRR is associated with metabolic parameters and is a useful predictor of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterolemia.
