Objectives The purpose of this study was to investigate the effect of BMI (body mass index), blood parameters and life pattern on KOQOL (Korean version of obesity-related quality-of-life scale) in Health checkup examinees of college students. Methods A group of 2992 test subjects took their medical examination. With their height and weight, we diagnosed obesity according to BMI. KOQOL was measured by survey conducted using self-report questionnaires, after excluding sexual life related question. We analysed relationship between KOQOL and BMI, blood parameters, life pattern using SPSS version 21.0. Results 1. There were significant differences in KOQOL according to BMI, gender, creatinine. 2. Female showed higher KOQOL than male. 3. Normal weight group showed lowest KOQOL in male, but underweight group showed lowest KOQOL in female. 4. Group who had more than 6 breakfast, lunch and dinner each in a week showed significantly lower KOQOL than that who didn't. Conclusions Obesity has significant influence on quality of life, so therefore there is a need for correct weight perception in weight control program, and KOQOL can be used in evaluating patients mental and social health.

PURPOSE: This study was conducted to verify the effects of a functional correction of the pain of patients with chronic low back pain(CLBP), and to examine the effect of dysfunctional factors on health-related quality of life. METHODS: A preliminary survey was first conducted on 90 patients with CLBP after functional orthodontic treatment. Some revised questionnaires were also prepared. The survey was distributed for approximately eight weeks, and 215 copies were used as the final analysis data, except for questionnaires that were inadequate, error or non-response. RESULTS: Path analysis using the structural equation model of CLBP patients showed a positive correlation between all the path coefficients and the potential factors. The multidimensional relationship between pain and dysfunction after orthognathic treatment was confirmed using three subdivisions of the pain variables as independent variables and the dysfunctional variables as the dependent variables. Multiple regression analysis was performed to examine the effects of pain on the dysfunction. To identify the multidimensional relationship between dysfunction and the health-related quality of life, eight sub-factors of dysfunctional variables were set as the independent variables, and multiple regression was analyses were performed with the dependent variables of the health-related quality of life. CONCLUSION: This study examined the structural and influence relationships of the functional correction with pain, dysfunction, and health-related quality of life. The results, suggest that a functional orthodontic treatment can be used as a positive program for the health-related quality of life. In addition, this study is meaningful in that it provieds useful information for intervention such as psychosocial change of patients.

The purpose of this study is to find out primary policies for reducing PM(particulate matter) as well as for improving the quality of life. Serious particulate matters cause to diverse healthcare and economy problems including business transactions. Unfortunately, until recently there are very few researches regarding the decision-making process for particulate matter policies. This study has applied the AHP(Analytic Hierarchy Process) method to develop cooperative policy making processes. The upper layer of this hierarchy analysis consists of four parts, i.e., transportation, production facility, living environment, and urban planning management. And each upper layer parts has their own three policies. 25 experts including policy-makers, academic researchers and industrial specialists have decided the primary policies and directions. The most significant PM policy is the mandatory reduction of air pollution and suspension of factory operation in the production industry. The results of this study can lead to guidelines for making environmental policies.

This study was performed to investigate the effects oi nutrition education program in physical health, nutritional status and health-related quality of life (HRQoL) of the Elderly in Seoul. Nutrition education program was consisted of healthy eating, prevention and diet therapy of obesity, diabetes, cardiovascular disease, and osteoporosis. Seventy eight free-living elderly people (13 male, 65 female), aged ${\geq}60 $ years participated in this program. Before and after nutrition education program, we surveyed the general characteristics, physical health, general health, nutrition status, and health-related quality of life to the subjects. All the subjects were divided into program completers (N=47) and noncompleters (N=31). All the data were analyzed by student t-test, chi-square test, paired t-test, and marginal homogeneity test using SPSS 9.0 version at p<0.05. After nutrition education program, physical activity and ADL maintained, however IADL improved in program noncompleters. In eating habits, 'slow eating' significantly improved in program completers in program completers. Nutrition knowledge and recognition scores were significantly increased in both groups, and accuracy score was significantly increased in program completers. However, nutrient-intakes of %RDA were not significantly changed in both groups, and it seemed to be more influenced by other factors such as 'family income' or 'family type' than by the nutrition education program. In HRQoL, social functioning was improved after nutrition education program in both groups (p<0.05). The nutrition education program has more effects on the program completers than on the noncompleters, and it is also needed social supports for the Elderly to fulfill their nutrient requirements.

Despite well-known benefits of physical activity for older adults, most older adults remain significantly underactive. The purpose of this study was to examine the effects of an inclusive, choice-based physical activity promotion program to increase lifetime physical activity levels of seniors on physical activity & health-related quality of life outcomes in older adults. The physical activity promotion program guided participants to choose activities that took into account their health, preferences, and abilities. It offered information on ways for them to exercise safely, motivate themselves, overcome barriers, and develop a balanced exercise regimen. A six-month comparison-group trial was conducted with older adults in community senior center. Changes in self-reported physical activity & health-related quality of life(SF-36) by group & within group were evaluated using t-test. Of 30 subjects, 22(73%) completed the trial. Subjects were aged 63 to 75 years(mean=$68.36{\pm}4.02$); 86% were female. The intervention group increased estimated caloric expenditure by 1975 calories/week in moderate intensity activities(MET${\geq}3.0$; p=.008), and by 2312 calories/week in physical activities of any intensity(p=.005). Between-group analyses showed that the changes were significantly different in both measures(p=0.17; p=032). The intervention group also significantly better scores on general health perception(p=.031) & vitality(p=.002). Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community settings.

Objectives: The objectives of this study were to investigate female labor workers' occupational stress and musculoskeletal symptoms and to identify the effects of their occupational stress and musculoskeletal symptoms on their health-related quality of life. Methods: A survey was conducted through direct interviews using a musculoskeletal symptoms questionnaire, the Korean Occupational Stress Scale(KOSS), and the Short-Form 36-Item Health Survey(SF-36). Subjects were 112 female labor workers in three factories in D city who were selected by convenience sampling. Results: Factors significantly affecting health-related quality of life were found to be: occupational stress(${\beta}$=-.36); degree of pain, with medium pain(${\beta}$=-.31) and extremely severe pain(${\beta}$=-.24); duration of pain, with more than 1 week-less than 1 month(${\beta}$=-.25) and more than 6 months(${\beta}$=-.16); frequency of pain, with once per 2-3 months(${\beta}$=-.22); responses to pain such as medical leave, use of worker's compensation insurance, task change, etc.(${\beta}$=-.16), and Slightly difficult(${\beta}$=-.16) versus Not hard at all. These variables demonstrated that health-related quality of life is 48%(F=11.72, p<.001) in female workers. Conclusions: To improve female labor workers' health-related quality of life based on the above results, occupational health managers should reduce the workers' occupational stress, develop and apply health interventions regarding musculoskeletal symptoms, prevent the early onset of musculoskeletal symptoms, and protect and promote the workers' health.

Objectives: This study was conducted to measure the decline in the health-related quality of life (HRQoL) associated with some diseases in South Korean adults. Methods: The EQ-5D health states in the 2005 National Health and Nutrition Examination Survey (NHNES) and the Korean EQ-5D valuation set were used to obtain the EQ-5D indexes of the study subjects. Each disease group was defined when the subjects reported to the NHNES that they were diagnosed with the corresponding disease during the previous 1 year by physicians. Since the distributions of the EQ-5D indexes in each subgroup were negatively skewed, median regression analysis was used to estimate the effects of specific diseases on the HRQoL. Median regression analysis produced estimates that approximated the median of the EQ-5D indexes and there are more robust for analyzing data with many outliers. Results: A total of 16,692 subjects (6,667 patients and 10,025 people without any disease) were included in the analysis. As a result of the median regression analysis, stroke had the strongest impact on the HRQoL for both males and females, followed by osteoporosis, osteoarthritis, rheumatic arthritis, and herniation of an intervertebral disc. While asthma had a significant impact on the HRQoL only in men, cataract, temporo-mandibular dysfunction, and peptic ulcer significantly affected the HRQoL only in women. Conclusions: Stroke and musculoskeletal diseases were associated with the largest losses of the HRQoL in Korean adults.

This study was carried out to analyze the relationship between body mass index (BMI) and general characteristics, psychological factors, eating habits, dietary behaviors, and health related quality of life using survey of 335 women aged 20 to 29 years in the Seoul and Kyungin areas. The 335 study subjects were divided into 4 groups by BMI ($kg/m^2$) levels; normal group($18.5{\leq}BMI{\leq}22.9$), overweight group($23.0{\leq}BMI{\leq}24.9$), mild obesity group($25.0{\leq}BMI{\leq}29.9$), and heavy obesity group ($BMI{\geq}30$) by Asian-Pacific obesity index criteria. The family income of the heavy obesity group was significantly (p<0.05) less than that of the normal weight group. Psychological factors, such as stress and depression of the normal weight group tended to be higher than those of overweight and obesity groups. The higher BMI level had the lower self-efficacy(p<0.05) among all subjects. As the BMI level increased, the preference for sweet, salty, and hot taste was significantly high. We found that normal weight women had healthier eating habits and dietary behaviors and a higher level of health-related quality of life than did those who were overweight, mildly obese, and heavily obese women. Overweight and mildly and heavily obese women were strongly associated with decreased physical and mental health related quality of life. Therefore, weight loss is desirable, and is likely to be beneficial for health-related quality of life in obese adult women. In conclusion, this study contains evidence to suggest that obesity management programs including different strategies according to obesity are required to determine the types of programs that are suitable for adult women, prior to their initiation of a program. The findings are helpful to inform researchers and practitioners who are seeking to implement appropriate strategies to create positive changes in the health behaviors of obese adult women.

PURPOSE: The objective of this study was to provide a basis for the need to apply psychological factors-based rehabilitation programs to osteoarthritis patients by understanding how the limitations on the activities of osteoarthritis patients relate to the health-related quality of life and depression. METHODS: This study assessed 1,994 osteoarthritis patients from the 7th Korea National Health and Nutrition Examination Survey (KNHANES, 2016-2018). The subjects were divided into two categories: with activity limitation and without activity limitation. A Chi-square test and logistic regression analysis were conducted. RESULTS: The EQ-5D index of subjects with activity limitation was .84 ± .16, it was .94 ± .12 in those with no activity limitation (p < .05). The diagnosis of depression was 16.8% and; 8.3% in those with and without activity limitation, respectively (p < .05). There was a significant difference in the odds ratio for each item in the EQ-5D. Moreover, the odds ratio for depression with an activity limitation was 2.171 (1.512 - 3.118) compared with no activity limitation. CONCLUSION: The activity limitation of osteoarthritis patients reduces the health-related quality of life significantly and increases the probability of depression. Therefore, the treatment of osteoarthritis patients should be approached considering the psychological conditions. Moreover, early diagnosis of depressive symptoms is needed to prevent symptom deterioration and increase the compliance with rehabilitation therapy.

Objectives : The purposes of this study were to examine the health-related quality of life(HRQoL) and to identify its related factors for a group of rural adults. Methods : The study subjects were 1,901 adults who were aged 40-70 years and who were living in Naju City, Jeollanamdo. The sociodemographic characteristics, health-related behavior, health status and global self-rated health were collected for statistical analysis. The health-related quality of life was measured by the Euroqol EQ-5D instrument. The differences on the EQ-5D index between the groups were assessed with t-test, ANOVA and hierarchical multiple regression analysis. Results : Overall, the mean value of the EQ-5D index was $0.884{\pm}0.140$ and this score was significantly different according to the socioeconomic characteristics, the health-related behavior, the health status and the global self-rated health. According to the results from the hierarchical multiple regression analysis, the HRQoL was significantly reduced for females, older subjects, and other subjects with no spouse and the subjects with osteoporosis, obesity, mental distress or poorer global self-rated health. Conclusions : The HRQoL for rural adults was related to the socioeconomic characteristics, the health status and the global self-rated health, A better understanding of the factors related to the HRQoL would help to improve the rural adults' quality of life.
