Background: Muscle undergoes change continuously with aging. Sarcopenia, in which muscle mass decrease with aging, is associated with various diseases, the risk of falling, and the deterioration of quality of life. Obesity and sarcopenia also have a synergy effect on the disease of the older adults. Objects: This study examined the risk factors for sarcopenia, sarcopenic obesity, and sarcopenia without obesity and developed prediction models. Methods: This machine-learning study used the 2008-2011 Korea National Health and Nutrition Examination Surveys in the analysis. After data curation, 5,563 older participants were selected, of whom 1,169 had sarcopenia, 538 had sarcopenic obesity, and 631 had sarcopenia without obesity; the remaining 4,394 were normal. Decision tree and random forest models were used to identify risk factors. Results: The risk factors for sarcopenia chosen by both methods were body mass index (BMI) and duration of moderate physical activity; those for sarcopenic obesity were sex, BMI, and duration of moderate physical activity; and those for sarcopenia without obesity were BMI and sex. The areas under the receiver operating characteristic curves of all prediction models exceeded 0.75. BMI could predict sarcopenia-related disease. Conclusion: Risk factors for sarcopenia-related diseases should be identified and programs for sarcopenia-related disease prevention should be developed. Data-mining research using population data should be conducted to enhance the effectiveness of early treatment for people with sarcopenia-related diseases through predictive models.

Purpose: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. Methods: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. Results: Right body image perception according to obesity was apparent between 70.6-81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69-2.57), but body mass index was not observed to be associated with weight control. Conclusions: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.

Background： Recently, adolescent obesity was increased and tended to become obese adults, facing increased risk for diabetes, cardiovascular disease. Even before reaching adulthood, adolescent obesity already was experiencing hypertension, dyslipidemia, and diabetes mellitus. The purpose of this study was to find prevalence of obesity of high school students in Jeju island and association between obesity and cardiovascular risk factors and association between childhood obesity and adolescent obesity. Method： The study subjects were 6,064 students of twenty-two high school in Jeju island and health survey data was gathered from high school health examination data and hospital health examination data from Aug. 1999 to Dec. 1999. Adolescent obesity was evaluated by ideal body weight method in 1998 and body mass index. Cardiovascular risk factors were checked total cholesterol, systolic and diastolic blood pressure, fasting blood sugar. In 1,534 students, obesity at primary school is checked by primary and middle school health record. Results： Prevalence of obesity in Jeju island high school students is 12.6% in male students, 13.3% in female students by ideal body weight method and 8.7% in male students, 8.5% in female students by body mass index. Prevalence of obesity of male students in city area and district area of Jeju island were each 12.9%, 10.3% and that of male students in city area was significantly higher. Prevalence of obesity of female students in city area and district area of Jeju island were each 12.9%, 14.2% and not significantly different. Prevalence of obesity of male students in general and commercial school group were each 13.9%, 10.1% and that of general school group was significantly higher. In female students, Prevalence of obesity general and commercial school group was not significantly different. Total cholesterol, systolic and diastolic blood pressure were significantly associated with degree of obesity in male and female students(p＜0.05) and fasting blood sugar was only significantly associated with degree of obesity in male students(p＜0.05). In 1,514 students checked by health record, Odds ratio of obesity at primary and middle school that at high school were 12.96∼22.77 and was significantly associated. Conclusion： Prevalence of obesity of high school students in Jeju island is very high and adolescent obesity was significantly associated with cardiovascular risk factors. Mostly childhood obesity tended to become adolescent obesity and program of control of obesity at childhood and adolescence is required.

This study attempts to develop a program for obesity prevention and management for students in primary, middle, and high school and was carried based on the program development process as suggested by Ewles and Simnett. Data were collected from September 1st to September 30th, 2000. The study method is as follows: 1) Reviewing the present obesity control programs practiced in primary, middle, and high school (196 schools total) in metropolitan, medium-sized, and small cities, 2) Surveying obesity students'(682 students total) perception of the obesity management in their school. 3) Reviewing the annual plan for obesity in primary, middle, and high schools 4) Analyzing the educational data (CD, VIDEO) for obesity The results are as below: I. The media researched related to obesity were mainly CD and video, aimed primarily primary school students and are biased in nature. 2. The results of how to manage obesity in students: the difficulty of obesity education in the primary school, is the arousal of a sense of shame among obese students and the lack of various educational data are the most. In the middle and high schools, a lack of various educational data, and no time or lack of time were prevailing concerns. Paramount in managing obesity is weight control, as answered by majority of primary, middle, and high school students. The major problem of obesity management is the non-cooperation of children. 3. Asked whether the weight controlling aspect of health care class was helpful or not, 51.4% of primary school students, and 71.6% of middle and high school students answered not. The most popular educational method used in health care class is the computer, with a 56.4% approval rating. Most 43.5% of respondents answered that they wanted the content of obesity management program to focus on how to lose weight. Therefore, based on the results, the obesity management program is constructed to the steps of assessment, planning, implementation, and evaluation. Assessment includes administering surveys on health needs among students and their parents and physique tests. Planning includes the set-up of long term and short term educational goal and the establishment of an operation system. Implementation includes education, exercise, behavior modification, and health service programs. Evaluation includes step-by-step evaluations for obesity reduction. After this study is conducted, the following should be further researched: More practical and systematic obesity management programs should be developed for the evaluation results. In addition, it is important to develop an appropriate media for obesity management the primary, middle and high school students.

Purpose: The purpose of this study is to analyze the correlation between obesity stress, self-esteem, and adaptation to school life according to body mass index of elementary school students in higher grades and to provide basic data for the development of health education programs. Methods: A convenience sampling method was used to select four elementary schools. Self-reporting questionnaires were distributed to the subjects to collect data, which were then analyzed using the SPSS 18.0 program. Results: The higher the obesity index, the more obesity stress the students experienced. Second, the lower the level of obesity, the higher both self-esteem and the level of adjustment to school life were. There was a meaningful correlation between obesity stress, self-esteem, and adjustment to school life. Conclusion: The study results are expected to be useful in serving as a basic material for the development of programs that can improve students' adjustment to school life and self-esteem while reducing their stress caused by obesity.

BACKGROUND/OBJECTIVES: The prevalence of morbid obesity in Korean women has consistently been increasing, while the overall prevalence rate of obesity in Korean women seems to be stable. In addition to bariatric surgery, intragastric balloons (IGBs), as a nonsurgical therapy, have been reported to be effective in weight loss. However, the beneficial effects of IGB in Korean women with obesity have not been fully investigated. The aim of this study was to evaluate the changes in fat mass in Korean women with obesity who had undergone IGB treatment for 6 mon. SUBJECTS/METHODS: Seventy-four women with obesity (body mass index [BMI] ≥ 25.0 kg/m²) were recruited. Clinical data, including general information, comorbidities with obesity, anthropometric data, and changes in the body fat composition before and after IGB treatment, were obtained from the subjects. RESULTS: Most subjects had one or more comorbidities, such as osteoarthropathy and woman's disease, and had poor eating behaviors, including irregular mealtimes, eating quickly, and frequent overeating. Body composition measurements showed that weight, fat mass, and waist-hip circumference ratio decreased significantly at 6 mon after IGB treatment. In particular, women with morbid obesity (BMI ≥ 30 kg/m²) showed 33% excess weight loss. There was no significant difference in skeletal muscle mass and mineral contents after IGB treatment. CONCLUSIONS: This study suggested that 6 mon of IGB treatment can be a beneficial treatment for obesity without muscle mass and bone mineral loss.

Objectives: In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. Methods: We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. Results: This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (β=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (β=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. Conclusions: Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

This study was a secondary analysis research using data from the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-2), 2017 to identify the relationships between obesity and physical activities and prevalence of osteoarthritis in menopause women. The subjects were 1,516 menopause women aged over 19 years who participated in the KNHANES VII-2, 2017. Data were downloaded from the KNHANES website and analysed through complex sampling design data analysis using IBM SPSS 21.0 program. Prevalence of osteoarthritis is 1.88 times higher in women with body mass index (BMI) above pre-obesity and non-abdominal obesity and 1.98 times higher in women with BMI above pre-obesity and abdominal obesity than in women with BMI normal or low weight and non-abdominal obesity. These results indicate that obesity prevention and management should be provided to prevention of osteoarthritis for menopause women and obesity should be considered body mass index and abdominal obesity.

objectives: This study was conducted to estimate medical expenditure attributable to overweight and obesity in adults with ischemic heart disease and stroke using Korea National Health and Nutrition Examination survey data and Korea National Health Corporation data. methods : The medical expenditure of ischemic heart disease and stroke related to overweight and obesity were composed of inpatient care costs, outpatient care costs and medication costs. The population attributable risk (PAR) of overweight and obesity was calculated from national representative data of Korea such as the National Health Insurance Corporation cohort data and 2005 Korea National Health and Nutrition Examination survey data. results: The medical expenditure attributable to overweight and obesity of ischemic heart disease were 97.4 billion won(74.1-122 billion won). and stroke were 64.6 billion won(33.1-98.1 billion won). Consequently, these costs corresponded to 11.4% of total medical expenditure due to ischemic heart disease and stroke. conclusion: We conclude that overweight and obesity have increased medical expenditure from ischemic heart disease and stroke in Korea. These findings provide important support for implementing overweight and obesity management strategies in Korea.
