This study was designed to evaluate the effects of arthritis and comorbid chronic conditions on the health-related quality of life (HRQoL) in the Korean older population. The study subjects were 2,708 Korean adults aged 65 and older from the $3^{rd}$ Korea National Health and Nutrition Examination Surveys data: 1,357 persons with a single chronic condition, such as arthritis, herniations of the intervertebral disc, osteoporosis, asthma, peptic ulcers, stroke, or cataract; 886 persons with arthritis and a second chronic condition described above; and 465 persons with no chronic condition. An analysis of covariance was performed to compare the EQ-5D index among the groups. The effects of arthritis, second chronic condition and their interactions were analyzed by multiple linear regression analysis. The results are as follows. Compared to men with arthritis only, men with stroke only, stroke and arthritis, or cataract and arthritis had a lower age adjusted EQ-5D index. Women with a stroke only, asthma only, cataract only, osteoporosis and arthritis, peptic ulcer and arthritis, stroke and arthritis, or cataract and arthritis had a lower age adjusted EQ-5D index than women with arthritis only. Arthritis and comorbid conditions had additive effects on the HRQol in both genders except for arthritis and stroke in women. In conclusion, comorbid chronic medical conditions in older people with arthritis may reduce the HRQoL in an additive manner.

Objectives: Health-related quality of life (HRQoL) is an important outcome for middle school students. This study was designed to illustrate the effect of social support and class cohesiveness associated on HRQoL. Methods: The subjects comprised 516 students from three middle schools in Daegu, South Korea that responded to a self-administered questionnaire in February 2014. The purposes of the questionnaire were explained to the subjects. Results: The total mean of HRQoL was $81.1{\pm}15.3$. Social functioning showed the highest score of $87.1{\pm}15.3$ and emotional functioning showed the lowest score of $73.8{\pm}21.5$. Teacher support (B=3.185, p=0.001) had a significant effect on the physical health summary scores. Class cohesiveness (B=2.237, p=0.022), friendships (B=5.102, p<0.001) and teacher support (B=2.498, p=0.006) had a significant effect on the psychosocial health summary scores. Finally, class cohesiveness (B=2.137, p=0.016), friendships (B=4.133, p<0.001) and teacher support (B=2.670, p=0.001) had a significant effect on the overall scores. Conclusion: The results of this study provide a basis for the development of strategies to improve health-related quality of life for middle school students, namely that relevant programs should be based on the improvement of social support and class cohesiveness.

Purpose: This study investigated the differences in physical function, self-efficacy (SE), and health-related quality of life (HRQoL) categorized by disease severity in community-dwelling patients with chronic obstructive pulmonary disease (COPD). Methods: This cross-sectional study included 182 patients with COPD selected from the pulmonology outpatient department of a tertiary hospital. Disease severity was measured using forced expiratory volume in 1 second (FEV1). Physical function, SE, and HRQoL were measured with the six-minute walking distance, Pulmonary Rehabilitation Adapted Index of Self-Efficacy (PRAISE), and St. George's Respiratory Questionnaire (SGRQ). Disease duration, FEV1, and 12-month history of exacerbations were obtained from medical records. Patients were categorized by Global Initiative for Chronic Obstructive Lung Disease (GOLD) category. Data were analyzed using the χ² test, and one-way ANOVA. Results: Most of the participants were male and nonsmokers. The disease duration was 10.76 ± 10.03 years, the mean FEV1% was 62.13 ± 22.80, and 70.3% of the participants were in GOLD category 2 (moderate) or milder. Half of the participants reported modified Medical Research Council scores ≥ 2. Patients in GOLD categories 1 and 3 (mild and severe) exhibited significantly higher PRAISE scores than those in the other groups (F = 8.23, p < .001). The total SGRQ scores were highest in GOLD 4 (very severe), indicating the lowest HRQoL. Significant differences were identified among GOLD 1, GOLD 2 and 3, and GOLD 4 (F = 9.92, p < .001). Conclusion: We identified potentially useful variables to comprehensively assess disease severity and tailor management strategies, including airflow limitation, and to determine the consequences of COPD from patients' perspectives.

Purpose: This study was conducted to identify the effects of education regarding action plans according to a self-monitoring program on self-management adherence, knowledge, symptom control, and health-related quality of life (HRQoL) among adults with asthma. Methods: Thirty-four patients were randomly assigned to the intervention group and thirty-two to the control group in this study. A tailored 50-minute intervention based on the contents of self-monitoring and action plans developed by the National Heart Lung and Blood Institute was provided to the intervention group. Structured and well developed questionnaires were used to measure the dependent variables. Results: There were no differences in all general and clinical characteristics, and the dependent variables between two groups in the pre-test. In the post-test, there were differences in the level of self-management adherence (t=4.41, p<.001), knowledge (t=2.26, p=.027), symptom control (t=-2.56, p=.013), and total HRQoL (t=2.14, p=.036) between the two groups, although there was a difference only in the sub-domain of emotion (t=2.03, p=.047) in HRQoL. Conclusion: This study found that action plans according to self-monitoring that enhance a participatory interaction in the treatment and care could help patients with moderate to severe asthma to engagead equately in self-care, to control their symptoms, and to improve their HRQoL. Further studies are still needed to identify longitudinal effects of this program.

The aim of this study was to evaluate the relationship between prosthetic status and health related quality of elderly by using EuroQol-5 dimension (EQ-5D) which is a standardized instrument used as a measure of health outcome. Data from 1,179 elderly subjects (over 65 years old) from the fifth Korea National Health and Nutrition Examination Survey were used in our analysis. Oral examination were conducted to obtain wearing prosthetic and needed prosthetic. EQ-5D is a widely used health condition measuring instrument. It consists of the five dimensions: Mobility, Self-care, Usual activities, Pain/discomfort and Anxiety/depression. EQ-5D index is a score calculated out of a weighting system. In this study, the mean score of the EQ-5D index among the elderly was 0.86. For EQ-5D index gender, female showed statistically significantly lower quality of life than male. The related factors EQ-5D index, when the lower demand for fixed prosthodontics and full denture. Wearers in partial and complete denture than non-wearers showed higher EQ-5D index. In order to improve EQ-5D index among the elderly who demand prosthetic status, which has lost its function through providing proper dental prostheses.

This study investigated the effects of overtime work on the health-related quality of life (HRQoL) of Korean blue-collar workers. This cross-sectional study collected data on 229 Korean blue-collar workers in six small-sized companies from October to November 2015. The data were analyzed using hierarchical multiple regression analysis to estimate the effect of overtime work while considering convergence variables. In the hierarchical regression model, when overtime work variable was included in the model, $R^2$ change was statistically significant. The significant predictors for HRQoL were overtime work (${\beta}=.152$, p=.025), depression (${\beta}=-.192$, p=.003) and night shift work (${\beta}=-.201$, p=.032). The results of this study provide a basic data for establishing optimal working hours standards for improving the quality of life of Korean blue-collar workers.

Objective: This study was to evaluate the health-related quality of life (HRQoL) among patients with diabetes in Korea and to compare them with the HRQoL of individuals without diabetes history. Methods: The study subjects were 17,655 adults aged over 19 who participated in the 5th Korea National Health and Nutrition Examination Survey (2010-2012). The EuroQoL-5Dimension was used to evaluate HRQoL. Chi-square test, t-test, ANOVA and multiple regression analysis were performed to test the difference of HRQoL in diabetic subjects and controls. Results: The mobility dimension was the highest reported problem: 36.4% for diabetic subjects. The proportion of any reported problem was significantly high among diabetic subjects compared with two controls in terms of mobility [reference group: diabetic subjects, chronic controls: adjusted odds ratio (aOR)=0.77, 95% confidence interval (95% CI)=0.66-0.91, healthy controls: aOR=0.61, 95% CI=0.50-0.75], self-care [reference group: diabetic subjects, chronic controls: aOR=0.68, 95% CI=0.55-0.83, healthy controls: OR=0.69, 95% CI=0.51-0.94]. and usual activities [reference group: diabetic subjects, chronic controls: aOR=0.85, 95% CI=0.72-0.99, healthy controls: OR=0.79, 95% CI=0.62-0.98]. Also, EQ-5D index were significantly low in subjects with diabetes compared to two controls. Conclusions: Subjects with diabetes had a significantly lower HRQoL compared with two controls. To improve the quality of life of diabetics, it is necessary to study various variables related to the quality of life, and develop and manage various health programs or welfare policies reflecting socio-demographic characteristics and health related features that affect the quality of life.

Purpose: The purpose of this study was to develop a resilience enhancement program applying mindfulness meditation (REP-MM) and evaluate the effects of the program on post-traumatic stress (PTS), resilience, and health-related quality of life (HRQoL) in patients with ileostomy. Methods: The REP-MM was developed by combining the resilience enhancement program with mindfulness meditation according to four patterns. The program was developed through identifying patients' needs, reviewing relevant literature, developing a preliminary program, and testing content validity and user evaluation. The participants were 55 patients with ileostomy. We conveniently assigned 27 patients to the experimental group and 28 to the control group. The study was conducted in conducted in a hospital from January 22 to May 30, 2019. The REPMM was provided to the experimental group, and conventional ileostomy care was provided to the control group using a nonequivalent control-group pretest-posttest design. Results: ANCOVA revealed that the levels of PTS (F = 321.64, p < .001), resilience (F = 111.86, p < .001), and HRQoL (F = 31.08, p < .001) in the experimental group were higher than those in the control group when comparing pretest to posttest changes. Conclusion: The REP-MM is effective in PTS, resilience, and HRQoL in patients suffering from post-stoma creation crisis. The REP-MM can induce positive self-recognition changes in patients with ileostomy through dispositional, situational, relational, and philosophical interventions. We suggest nurses reduce PTS and improve resilience and HRQoL in patients with ileostomy.

Background: Patients with chronic liver diseases (CLD) may have compromised health related quality of life (HRQoL). Hepatitis B virus (HBV) infection has long been the leading cause of CLD including liver cancer and cirrhosis. Knowledge on different symptom profiles of CLD should help in development of comprehensive treatment and patient care plans. Objective: To access the facets of HRQoL in chronic liver diseases throughout their spectrum of severity. Materials and Methods: A cross-sectional study was conducted in the First Affiliated Hospital of Kunming Medical University in Yunnan Province of China. Both out- and inpatients undergoing treatment protocols for different HBV related liver disease states were consecutively collected from December 2012 to June 2013. ANOVA was used to compare the mean scores of EQ-5D and chronic liver disease questionnaire (CLDQ) among 5 disease groups. The relationship between demographic variables predicting global CLDQ scores and the domains of CLDQ was analysed. Results: A total of 1040 patients including 520 without complications, 91 with compensated cirrhosis, 198 with decompensated cirrhosis, 131 with HCC and 100 with liver failure were recruited. All domains of CLDQ, the means of EQ-5D value and EQ VAS exhibited significant decline with worsening of disease severity from uncomplicated HBV to liver failure. The multivariate regression demonstrated the reduction of mean scores of CLDQ domain at advanced stage. Patients with liver failure and HCC had more HRQoL impairment than other disease states. No effect of patient gender was found. Patient age was associated with 'fatigue' and 'worry' domains (p=0.006; p=0.004) but not with other domains and global scores of CLDQ and ED-5D. Conclusions: The HRQoL in chronic hepatitis B patients is greatly affected by disease states. Care for HBV-related diseases should consider not only the outcomes of treatment strategies but also improvement in patient wellbeing.

Purpose: This study was performed to assess problems associated with sleep (short and long sleep duration) and to identify risky subgroups with sleep problems among adult cancer survivors. The study is based on the Korea National Health and Nutrition Examination Survey (KNHANES VI and VII) from 2013 to 2016. Methods: The sociodemographic and clinical data of 504 Korean cancer survivors aged 20-64 years was extracted from the KNHANES VI and VII database. Descriptive statistics for complex samples was used, and decision-tree analyses were performed using the SPSS WIN 24.0 program. Results: The mean age for survivors was approximately 51 years. The mean sleep duration was 6.97 hours; 36.2% of participants had short (< 7 hours) and 9.9% had long (> 8 hours) sleep duration. From the decision-trees analyses, the characteristics of the adult cancer survivors related to sleep problems were presented with six different pathways. Sleep problems were analyzed according to the survivors' sociodemographic information (age, education, living status, and occupation), clinical characteristics (body mass index, hypercholesterolemia, and anemia) and health-related quality of life (HRQoL). The HRQoL (${\leq}0.5$ or > 0.5 cutoff point) was a significant predictor of the participants' sleep problems because all six pathways were started from this predictor in the model. Conclusion: Health care professionals could use the decision-tree model for screening adult cancer survivors with sleep problems in clinical or community settings. Nursing interventions considering these specific individual characteristics and HRQoL level should be developed to have adequate sleep duration for Korean adult cancer survivors.
