As overweight and obese people have increased, obesity management programs have generated much concern in Korea. Many types of obesity management programs were operated, aimed at reducing weight, BMI, body fat percentage and so on. This study was conducted to review the features of studies in obesity management programs and systematically assess the effects which were published from 1995 to 2006 in Korea. Databases were systematically searched for published data in Korea. It were KISS (Korean studies information services system) and KERIS (Korean Education research information system), which were major literature search systems for all academic fields in Korea. Total 114 studies were initially identified, of which 21 satisfied our inclusion data. The effects of obesity management programs were assessed on the results in weight, BMI (body mass index), HDL (high density lipids), body fat percentage, self-efficacy. Effect size estimated on the equation of M1 - M2 / Sp, where M1 was mean of the experimental group, M2 was the mean of control group, and Sp was the pooled standard deviation. Magnitude of effect size was interpreted by using Cohen's definition. Cohen described small, medium, and large effect sizes as 0.2, 0.5, and 0.8 respectively. The studies about obesity management programs were the most published in 2005(26.1%). Obesity management programs were popularly operated as the type of 12 weeks intervention, exercise intervention(52.4%), quasi-experimental study(85.7%). Ten studies reported significant effects on weight, and nine studies reported significant effects on BMI and HDL. Only five and three studies reported significant effects on body fat percentage and self-efficacy respectively. The effects of each outcome were generally significant when the studies included these elements, intervention over 10 weeks, evaluation over 3 times, a comprehensive program (exercise, nutrition education, behavior modification) and reinforcing factors (self-monitoring, group discussion, one's goal setting, and etc.). Effective obesity management programs should contain these essential elements and objectives of obesity management programs must be set out evident at the beginning. The participants should be registered, educated and evaluated by continuous obesity management programs.
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.

BACKGROUND/OBJECTIVES: Childhood obesity has become a global epidemic. Development of effective and sustainable programs to promote healthy behaviors from a young age is important. This study developed and tested an intervention program designed to promote healthy eating and physical activity among young children in South Korea by adaptation of the US National Aeronautics and Space Administration (NASA) Mission X (MX) Program. SUBJECTS/METHODS: The intervention program consisted of 4 weeks of fitness and 2 weeks of nutrition education. A sample of 104 subjects completed pre- and post- surveys on the Children's Nutrition Acknowledgement Test (NAT). Parents were asked for their children's characteristics and two 24-hour dietary records, the Nutrition Quotient (NQ) at baseline and a 6-week follow-up. Child weight status was assessed using Korean body mass index (BMI) percentiles. RESULTS: At baseline, 16.4% (boy: 15.4%; girl: 19.2%) of subjects were overweight or obese (based on $BMI{\geq}85%tile$). Fat consumption significantly decreased in normal BMI children ($48.6{\pm}16.8g$ at baseline to $41.9{\pm}18.1g$ after intervention, P < 0.05); total NQ score significantly increased from 66.4 to 67.9 (P < 0.05); total NAT score significantly improved in normal BMI children (74.3 at baseline to 81.9 after the program), children being underweight (from 71.0 to 77.0), and overweight children (77.1 at baseline vs. 88.2 after intervention, P < 0.001). CONCLUSIONS: The 6-week South Korean NASA MX project is feasible and shows favorable changes in eating behaviors and nutritional knowledge among young children.
Purpose: The purpose of this study was to develop an obesity management program for obese children and examine its effects on body composition, self-efficacy, and health promotion. The obesity management program was based on a KAP & HBM mixed model and consisted of health education and group playing exercises. Method: This study was implemented at one elementary school in K city for a total of 12 weeks. The study subjects were a single group, and their body composition, self-efficacy, and health promotion were assessed at both pre-treatment and post-treatment. Data were analyzed by Wilcoxon Signed Rank Test using SPSS WIN 20.0. Result: After the program, the average height of subjects increased by 0.9cm (p=.001), whereas BMI decreased by $0.64kg/m^2$ (p=.003), obesity index decreased by 3.79% (p=.003), and body fat decreased by 1.34% (p=.002). There were significant effects on diet self-efficacy (p=.027), exercise self-efficacy (p<.001), and health promotion (p=.001). Conclusion: This obesity management program reduced the degree of obesity and improved self-efficacy and health promotion. Therefore, the obesity management program is an effective intervention method for elementary-aged obese children.

Purpose: This research was conducted to compare the effect of a wellness program on knowledge of obesity and weight loss in women schizophrenia inpatients. Methods: A nonequivalent control group pretest-posttest design was used for this study. A total of 44 patients with schizophrenia were randomly divided into an experimental group (22) and a control group (22) in a 12-week multimodal weight control program. For 6 weeks, the experimental group received approximately an hour of teaching on obesity interventions and for another 6 weeks one hour of teaching on exercise and weight control interventions while the control group received the usual care. The outcome variables were measured before and after the program. Data was analyzed with the ${\chi}^2$-test and t-test using PASW Statistics 18. Results: For those who completed the weight control program, there was a mean weight loss of 1.37kg by the end of the intervention. The experimental group showed significant improvement in knowledge of obesity and weight loss. Conclusion: The wellness program was effective in reducing the weight of women schizophrenia patients as well as being effective in increasing knowledge of obesity. Therefore, nurses must consistently educate women schizophrenia inpatients about health care and knowledge of obesity.
Purpose: The aim of the study was to determine the effects of a community based participatory program in obese middle-aged women. Methods: One-group pretest-posttest design was used. The subjects were 35 middle-aged women. Data were collected at public health centers in Chungcheongnam-Do from March to May, 2013. To evaluate the effect of the program, physiological indexes(body mass index, skeletal muscle mass, body fat mass, visceral fat area) and health behavior indexes(dietary practice guidelines score, moderate physical activity, drinking frequency) were measured. Analysis was performed using a Wilcoxon Signed Rank Test. Results: After the program, physiological indexes (BMI, BFM, SMM, VFA) and health behavior indexes (dietary guidelines scores, frequency of physical activity, drinking frequency) were significantly improved. Conclusion: The community based participatory obesity program by public health centers is considered to be effective. Therefore, greater effort is needed for better participatory program development of several health promoting fields, and more research is needed in order to examine a continuous effect.

BACKGROUND/OBJECTIVES: Abdominal obesity is associated with metabolic disorders, and, in recent years, its prevalence in Korea has continuously increased. The change of lifestyle, particularly diet, is critical for the reduction of abdominal obesity. This study evaluated the effectiveness of an intervention focused on dietary self-efficacy and behaviors on the improvement of abdominal obesity. SUBJECTS/METHODS: Abdominally obese adults with additional cardiovascular risk factors were recruited through 16 medical facilities in South Korea from the year 2013 to 2014. The participants were randomly divided into 2 groups: an intensive intervention group (IG) that received a multi-component intervention to reduce abdominal obesity, by mainly focusing on dietary attitude and dietary behavior change, and a minimal information intervention group (MG) that received a brief explanation of health status and a simple recommendation for a lifestyle change. The interventions were provided for 6 mon, and health examinations were conducted at baseline, 3-, 6-, and 12-mon follow-ups. A path analysis was conducted to identify the process governing the changes in abdominal obesity. RESULTS: The IG showed an improvement in self-efficacy for eating control and diet quality at 6-mon follow-up. Abdominal obesity improved in both groups. Waist circumference was observed to be decreased through the path of "improved self-efficacy for eating control in food availability-eating restriction-improved dietary quality" in IG. Most changes in follow-ups were not significantly different between two groups. CONCLUSIONS: The intensive program targeting the modification of dietary behavior influenced management of abdominal obesity, and the effect occurred through a step-by-step process of change in attitude and behavior. Generally, improvements were also seen in the MG, which supports the necessity of regular health check-ups and brief consultation. The results can be used for further development and implementation of more successful interventions.
Purpose: The purpose of this study was to examine the effects of a Combined Exercise Program on Obesity and Metabolic Syndrome Factors for Chronic Psychiatric Inpatients. Methods: Thirty two subjects participated in this program who were admitted into a national mental hospital of C city. All measurements were done at baseline, 4 week, 8 week, and 12 week during the program. The effectiveness of the program was evaluated according to the change of body mass index, body fat, waist circumference, total cholesterol, high density lipoprotein cholesterol, triglyceride, and fasting blood sugar. Collected data was analyzed by frequency, percentage, and repeated measures ANOVA with SPSS WIN 19.0. Results: There were statistically significant differences in the body mass index (p=.002), body fat (p<.001), waist circumference (p<.001), triglyceride (p=.020), and fasting blood sugar (p=.008). However, there were no statistically significant differences in the total cholesterol, or high density lipoprotein cholesterol. Conclusion: The results of this study showed that a combined exercise program has positive effect on obesity and metabolic syndrome factor. Thus, a Combined Exercise program is recommended as an intervention to improve obesity and metabolic syndrome factors for chronic psychiatric inpatients.
Purpose: The purpose of this study was to develop and apply a motivation-strengthening obesity management program for obese subjects with visual impairment and evaluate its effects. Methods: The program development and evaluation periods were from March to August 2018. The study design was an experimental study of non-equality, control repeat design. 25 subjects in the experimental group participated in the 12-week obesity management program and the 26 people in the control group did not. Results: The motivation-strengthening obesity management program included stretching exercises for 30 minutes in the morning five times a week. In addition, counseling, education, and group discussions were continued once a week for motivational strengthening. Special custom exercises for blind patients were also completed once a week simultaneously. Both of these activities were continued for 50 minutes a week for a total of 12 weeks. Measurements were recorded periodically to identify the sustained effects of the program. The obese subjects with visual impairment improved their knowledge of obesity, perceived disability, self-efficacy of exercise, and quality of life related to obesity through the motivational obesity management program. Waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood sugar were also improved in obese subjects. Conclusion: The study findings indicate that this program could be an active intervention for the control of weight gain in participants with visual impairment. Therefore, the motivation-strengthening program based on the ADDIE (Analysis, Design, Development, Implementation& Evaluation) model could be an effective strategy for better health outcomes of obese subjects with visual impairment.
