Purpose: This study was designed to construct a structural model for explaining model health-related quality of life in acquired people with physical disabilities. Method: The hypothetical model of this study was consisted of 6 latent variables and 14 observed variables. Exogenous variables included in this model were physical status and economical level. Endogenous variables were social attitudes, family function, self-esteem, and health-related quality of life. Data were collected from 226 acquired people with physical disabilities residing in Seoul and Kyunggi-do from January to February, 2005. The collected data were analyzed using SAS 8.2 version and LISREL 8.32 version program. Results: The results of the fitness test of the modified model were follow as; ${\chi}^2=67.479$ (df=50, p=.05), GFI=.959, AGFI=.914, SRMR=.049, NFI=.961, NNFI=.979, CN=249.244. Health-related quality of life was influenced directly by physical status, economic level, and social attitudes and accounted for 88.8% of the variance by these factors. Conclusion: These results suggest that physical status is the most significant effect on health-related quality of life, and social attitudes and economic level are important factors having influences on health- related quality of life. Therefore improving physical status and economic level, and modifying negative attitudes are necessary to increase health-related quality of life of acquired people with acquired physical disabilities.

Purpose : This study examined the relationship between oral health management behavior and subjective health perception by using a tool that measures health-related quality of life named EQ-5D. The findings are expected to provide fundamental data for developing diverse programs, including health- and oral-health-related educational media, to ultimately enhance people's health-related quality of life. Methods : Adults over the age of 20 were extracted from the raw materials of the 8th national health and nutrition examination survey conducted in 2019. Among them, 4034 were finally chosen as the study subjects after checking the response distribution of relevant questions and excluding inadequate samples. Variables included general characteristics, health management behavior, oral health management behavior, subjective health perception, and EQ-5D level. Cross-tabulation test, independent t-test, one-way analysis of variance, and linear regression analysis were conducted using SPSS 25.0. Results : EQ-5D, which measures the level of health-related quality of life, was high when the subjects had a medical check-up experience, no experience of unsatisfactory medical service, and did not get an influenza vaccination (p<.001). The quality of life was higher when the subjects received dental inspections, did not require treatment, and used oral care goods (p<.005). Health-related quality of life was also higher when the subjective health level and subjective oral health level were high. Conclusion : Results indicate that subjective health, oral health perception level, and quality of life together were high when people had a regular check-up, did not neglect treatment, and used oral care goods. Considering the findings of this study, check-up programs that are customized for each age group are necessary. Health-related quality of life could be enhanced through the provision of diverse medical services and active efforts to prevent any medical blind spot.

Purpose: This cross-sectional study was carried out to identify factors influencing the health-related quality of life according to socioeconomic level during early adolescence. Methods: Participants were 617 middle school students in $1^{st}$ and $2^{nd}$ grade. All measures were self-administered. Data were analyzed using SPSS 21.0 program and factors affecting the health-related quality of life were analyzed by t-test, ANOVA, Duncan test, Pearson's correlation coefficient, and multiple regression analysis. Results: According to the level of Family Affluence Scale (FAS), 19.1% of the participants were in the high class, 66.5% in the middle class, and 14.4% in the low class. We have found statistically significant differences among the high, middle, and low classes regarding the health-related quality of life, health perception, resourcefulness, family function, and social capital. The most influential factors of the health-related quality of life were found to be resourcefulness, family function, and social capital in the high and the middle class. Conclusion: The implication of this study is that it is important for the Education Ministry and middle school teachers to help adolescents develop internal coping resources as well as to develop school-curriculums considering social values and norms related to social capital in order to improving their health-related quality of life.

Purpose : Rapid population aging in South Korea is emerging as serious social problems, and interest in the health-related quality of life of the elderly is also increasing. Therefore, this study attempted to provide basic data to develop measures to improve the health-related quality of life of the elderly by identifying the impact of the elderly's dietary lifestyle on the health-related quality of life. Methods : Utilizing raw data from the Korea national health and nutrition examination survey spanning from 2011 to 2020, this study focused on individuals aged 65 and above. After excluding cases with missing data, 12,731 individuals were included in the final analysis. Various statistical methods including frequency analysis, t-tests, ANOVA, Scheffé test and hierarchical regression analysis were performed using SPSS 25.0 for windows. The statistical significance level (α) was set at .05. Results : The main results of this study were as follows. Firstly, dietary lifestyle exhibited variations depending on gender, age, education level, individual income, basic livelihood type, household type, self-rated health status, and chewing difficulty (p<.001). Secondly, there were disparities in health-related quality of life (as measured by the EQ-5D index) based on gender, age, education level, residence, individual income, basic livelihood security, self-rated health status, and chewing difficulty (p<.001). Thirdly, the EQ-5D index showed that elderly individuals' dietary lifestyle adversely impacted their health-related quality of life (F=353.74, p<.001). Conclusion : Therefore, it is necessary to prepare policies to improve the health-related quality of life by maintaining a proper diet for the elderly, and customized support and management is required taking into account the elderly's gender, age, education level, individual income, basic livelihood security, household type, self-rated health status, chewing difficulty etc.

This study aimed to determine the effect of depression between the health-related quality of life and pain in elderly persons with physical disabilities. A total of 111 patients who were treated at hospital B (Seoul, Daejeon, Daegu, Gwangju, and Busan) participated in the Survey. The SF-36 Health Assessment was used to determine the quality of life of subjects, the Korean version of the Geriatric Depression Scale-Short form to assess the level of depression, and Numeric Rating Scale to determine the level of pain. To determine the moderating effect of depression on the relationship between quality of life and pain, simple regression analysis, and the Sobel test were performed. There was a significant negative correlation between health-related quality of life and pain (r<-.3, p<.05), and a significant positive correlation between depression and pain (r=.251, p<.05). Thus, health-related quality of life had a simple regression relationship with depression and pain. Depression also showed a mediating effect between health-related quality of life and pain. The results of this study suggest that depression mediates between pain and quality of life.

This study was to identify the relationship between health promoting behaviors and health related quality of life at acculturation environment of Chinese international students in Korea. From November 2010 to December 2011, 395 Chinese international students in undergraduate, masters or doctorate courses from 10 universities and graduate schools in Seoul and vicinity participated in self-report survey of the acculturation level, the health promoting behaviors and SF-12, the health related quality of life. The data of 395 students were classified to 3 groups based on the acculturation level. The low level group showed the health promoting behaviors strongly influence the physical component score of quality of life. As the acculturation level increased, the health promoting behaviors closely affected to the mental health-related quality of life. The results indicated that the acculturation level may be control variable to define the relationship between the health promoting behaviors and the health-related quality of life.

Purpose: This study was to identify health behavior, health service use, and health related quality of life of adult women in one-person and multi-person households. Methods: It was used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-2017). Subjects were 2,522 women with age of 19 to 64 years in 2017. Complex sampling design and data analysis were performed using SPSS 20.1. Results: Women in one-person households had higher rates of alcohol drinking (${\chi}^2=13.77$, p=.003), smoking (${\chi}^2=16.07$, p=.001), unmet medical care (${\chi}^2=8.77$, p=.004) and non-practice of cancer screening (${\chi}^2=13.77$, p=.003) compared to women in multi-person households. Health-related quality of life was also lower for women in one-person households (t=-2.46, p=.015). Factors affecting health-related quality of life in one-person households were household income, job status, and unmet dental care, having 32.4% explanatory power. One-person household women with low incomes, no jobs, and unmet dental care showed low health-related quality of life. In comparison, factors affecting health-related quality of life of women in multi-person household women were age, education level, unmet medical care, and unmet dental care, having 10.4% explaining power. Women in multi-person households with age of 60-64, low education level, unmet medical care, and unmet dental care showed low health-related quality of life. Conclusion: Health promotion strategies should be developed based on unique understanding of social, economic, and health of adult women in one-person and multi-person households.

Objective: Patients with COPD have a lower overall quality of life than normal people. If patients with COPD do not regularly perform physical activities, their exercise capacity is reduced. It could lead to muscle loss, and negatively affect their general physical, social, and psycho-social status. The purpose of this study was to examine association with physical activity, sedentary life time and health-related quality of life in patients with COPD. Method: Of the total of 22,948 participants surveyed in Korean National Health and Nutrition Examination Survey (KNHANES 2013-2015), 8,626 participants were used for this study. Of these, under 40 years, over 80 years, missing values and abnormal values were excluded. Study variables included physical activity level, sedentary time and health-related quality of life variables. The physical activity level assessment tool was measured using International Physical Activity Questionnaire (IPAQ). Sedentary time referred to the amount of sitting time without moving the body. EQ-5D (Euro Quality of Life-5 Dimensions) was used as an index of health-related quality of life. Control variables were age, gender, income level, education level, marital status, comorbidity, smoking, BMI, cough, sputum, COPD severity. For this study, descriptive analysis, T-test, ANOVA and multivariate regression analysis were performed. Results: Of the 1,092 patients with COPD, 76.1% (n=831) were male and 23.9% (n=261) were female, while 39.0% (n=2,939) were male and 61.0% (n=4,595) were female in the comparison group without COPD. The COPD group with high level of physical activity showed a high level of EQ-5D scores ($0.9349{\pm}0.11$, p <0.001). Among patients with COPD, after adjusting for control variables, physical activity and sedentary time (physical activity level, Β=0.047, p <.001), (sedentary time, Β=-0.017, p <.05) were associated with health-related quality of life. Conclusion: Patients with COPD have a higher quality of life as their physical activity increases and the quality of life decreases as the time spent sitting increases. This study suggests that public health experts should consider improving COPD patient physical activity.

Background: This study was aimed at obtaining basic data necessary to develop alternatives to improve the oral health-related quality of life of the elderly by investigating dry mouth and oral health-related quality of life of patients visiting the N Dental Clinic in Jeollanam-do. Methods: From November 2021 to September 2022, data were collected using a self-report survey of adults aged 50 years or older. Of the 300 questionnaires collected, 280 had insufficient data because of missing entries. Results: Analyzing the satisfaction level of oral health-related quality of life according to the participants' medical use and subjective oral health recognition, "what do you think your oral health is like" showed significant differences (p< 0.001). Dry mouth and satisfaction were positively correlated with the oral health-related quality of life (β=0.42, p= 0.00). Factors affecting the quality of life related to oral health were "total score of oral dryness" (β= 0.395) and "what do you think your oral health is like" (β=0.224). Conclusion: The results of this study suggested that systematic intervention, such as oral health programs, suitable for age may improve the oral health-related quality of life.

The purpose of this study was to understand the ability of the elderly to activity of daily living, assess their quality of sleep and level of depression at home and analyze how such relate health related quality of life. The subject was 223 senior over 65 years old who lived in B Metropolitan City. Descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation and stepwise multiple regression were performed using SPSS WIN 14.0. The major findings of this study are as follow: 1) 34.1% of the respondents experienced a degree of sleep disorder and 57.8% were vulnerable to depression. 2) Activity of daily living, quality of sleep and depression were related to health related quality of life to a statistically significant degree. quality of sleep, activity of daily living positively related to health related quality of life. level of depression related to health related quality of life. Stepwise multiple regression analysis revealed the most powerful predictor of health related quality of life was depression. While age, level of education and quality of sleep were also found as significant predictor variables. Based on these results, it is necessary to perform more studies on health related quality of life and related factors according to that in various settings. Especially, to develop a program intended to improve the health related quality of life of the elderly at home, we need to consider not only physical factors but also psychological factors.
