Purpose : This descriptive research study aimed to investigate the relationship among academic self-efficacy, sleep quality, and quality of life(QoL) and to identify the factors that affect quality of life(QoL) in nursing students during the COVID-19 pandemic. Method : A total of 214 nursing students from three South Korean colleges were included in the study. Collected data were analyzed using the SPSS/WIN 21.0 program. Independent t-test and one-way analysis of variance were used to analyze the differences in academic self-efficacy, sleep quality, and quality of life(QoL) according to general characteristics. In addition, post-hoc Scheffè test and Pearson's correlation coefficient were used to examine the relationship among the three parameters. Stepwise multiple regression analysis was conducted to identify influential factors on the nursing students' quality of life(QoL). Results : The average academic self-efficacy, sleep quality, and quality of life(QoL) scores were 3.15±0.27, 32.28±7.54, and 81.12±13.11, respectively. Quality of life(QoL) positively correlated with academic self-efficacy but negatively correlated with sleep quality. Academic self-efficacy negatively correlated with sleep quality. Sleep quality, satisfaction with major, sex, average income, and academic self-efficacy influenced quality of life(QoL), whose explanatory power was 34.9 %. Conclusion : Sleep quality was the most influential factor of quality of life(QoL). However, further studies to validate our findings and studies focusing on developing intervention programs to improve nursing students' sleep quality and quality of life(QoL) are warranted.

Objectives: The purpose of this study was to systematically analyze and examine the relationship between the number of lost teeth and quality of life (QoL) among elderly. Methods: Papers published in Korean and English between 2000 and 2020 were searched. Relevant papers were selected by two independent readers according to predefined exclusion criteria. Quality assessment and consistency tests were conducted using ROBIS. Results: Twelve of the 854 studies were targeted, and the analysis confirmed that tooth loss was related to a decrease in the QoL in 11 studies. Tooth loss negatively affected the QoL among the elderly. However, one study indicated that the QoL and number of teeth were not related. Rather, dry mouth affected the QoL, and cavities caused by oral dryness led to tooth loss. Most of the selected studies indicated that the QoL of elderly individuals with a single tooth was higher than that of those with no teeth. Conclusions: This study provides strong evidence that tooth loss in the elderly is associated with impairment of QoL.

This study examines how economic and psychological characteristics affect the quality of life (QoL) of elderly individuals age 60 and older, who live in the Seoul-metropolitan area. Relationships among socio-demographic status, economic conditions, psychological characteristics, family life, health status, and QoL are examined by t-test and ANOVA(Duncan's test as post hoc multiple comparisons), and the multiple regression analysis is used to estimate QoL determinants in the elderly. The major findings of the study are as follows. First, younger age, higher education levels, better health status, harmonious family relations, higher levels of household income, lower levels of loneliness, and higher self-esteems are related to higher QoL levels. Second, the impacts of factors on QoL are differentiated according to tercile groups that divide monthly allowance of respondents into three categories: below normal (threshold amount below 21MW), near normal (threshold amount between 21MW and 35MW), and above normal (threshold amount above 35MW). For each tercile group, poor health status or higher loneliness have negative effects on QoL, while harmonious family relationship has a positive effect. For the below-normal group, years of education or self-esteem have positive effects, while age or retirement status have negative effects when controlling for other factors. For the near-normal group, being married, or perceived financial insecurity create lower QoL levels, while higher self-esteem increases QoL levels. For the above-normal group, being widowed, employed, or retired have positive effects on QoL, when controlling for other variables. Third, even among elderly with high allowances, the effects of health status and family relationship are significant determinants that explain QoL levels. This result suggests that, for te elderly, poor health status and poor family relationships severely decrease QoL in later life, regardless of economic condition.

Quality of life in addition to various medical problems in children with end-stage renal disease (ESRD) should be objectively assessed to accomplish normal growth and development during childhood. However, unfortunately, studies of quality of life (QoL) in children with ESRD have been not popular yet and there are only fewer suitable assessment tools compared with adults. Recently, disease-specific modules to evaluate QoL in children with chronic disease such as ESRD have been developed. This review was made to introduce these QoL instruments for children and help the clinical application of them.

Introduction: Quality of life (QoL) issues are of importance in relatives of women with breast cancer (BC)as caregivers in neglecting their own needs due to care of a patient and also as women regarding the potential risk of themselves developing BC. The objectives in the present study were to compare the QoL of female relatives of women in treatment for breast cancer. To date, no study had examined multi-dimensional QoL in accompanying people as compared them into two groups of female relatives whose first degree and second degree. Methods: QoL of female relatives was assessed using the Quality of Life-Family Version (QOL-FV) scale. Relationships between socio-demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and Crosstabs tests. Results: The mean age of the female relatives was 37.6 years, and nearly 48% had a university education. It was found that first degree relatives had worse QoL in all domains except physical wellbeing than second degree relatives. Conclusion: This study showed that being female relatives of BC, especially first-degree, affect QoL negatively. Health care providers are of an important role in the stage of information related to genetic influence of BC.

Purpose: This study evaluated the changes in nutritional status based on quality of life (QoL) item-level analysis to determine whether individual QoL responses might facilitate personal clinical impact. Materials and Methods: This study retrospectively evaluated QoL data obtained by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) and Quality of Life Questionnaire-Stomach (QLQ-STO22) as well as metabolic-nutritional data obtained by bioelectrical impedance analysis and blood tests. Patients were assessed preoperatively and at the 5-year follow-up. QoL was analyzed at the level of the constituent items. The patients were categorized into vulnerable and non-vulnerable QoL groups for each scale based on their responses to the QoL items and changes in the metabolic-nutritional indices were compared. Results: Multiple shortcomings in the metabolic-nutritional indices were observed in the vulnerable groups for nausea/vomiting (waist-hip ratio, degree of obesity), dyspnea (hemoglobin, iron), constipation (body fat mass, percent body fat), dysphagia (body fat mass, percent body fat), reflux (body weight, hemoglobin), dry mouth (percent body fat, waist-hip ratio), and taste (body weight, total body water, soft lean mass, body fat mass). The shortcomings in a single index were observed in the vulnerable groups for emotional functioning and pain (EORTC QLQ-C30) and for eating restrictions (EORTC QLQ-STO22). Conclusions: Long-term postoperative QoL deterioration in emotional functioning, nausea/vomiting, pain, dyspnea, constipation, dysphagia, reflux, eating restrictions, dry mouth, and taste were associated with nutritional shortcomings. QoL item-level analysis, instead of scale-level analysis, may help to facilitate personalized treatment for individual QoL respondents.

Purpose: The aims of this study were to make serial comparisons of the quality of life (QoL) between patients who underwent total gastrectomy and those who underwent distal subtotal gastrectomy for gastric cancer and to identify the affected scales with consistency. Materials and Methods: QoL data of 275 patients who were admitted for surgery between September 2008 and June 2011 and who underwent subtotal gastrectomy or total gastrectomy were obtained preoperatively and postoperatively at 3, 6, 9, 12, 18, and 24 months. The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and the gastric cancer specific module, the EORTC QLQ-STO22, were used to assess QoL. Results: QoL, as assessed by the global health status/QoL and physical functioning, revealed a brief divergence with worse QoL in the total gastrectomy group 3 months postoperatively, followed by rapid convergence. QoL related to restrictive symptoms (nausea/vomiting, dysphagia, reflux, and eating restrictions) and dry mouth was consistently worse in the total gastrectomy group during the first 2 postoperative years. Conclusions: The general QoL of patients after gastrectomy is highly congruent with subjective physical functioning, and the differences between patients who undergo total gastrectomy and subtotal gastrectomy are no longer valid several months after surgery. In order to further reduce the differences in QoL between patients who underwent total gastrectomy and subtotal gastrectomy, definitive preoperative informing, followed by postoperative symptomatic management, of restrictive symptoms in total gastrectomy patients is the most rational approach.

This paper proposes a method of modelling the informative dropouts with QoL(quality of life) in survival analysis. QoL is the index to measure the health related quality of life of a patient who got some treatments for a disease. Dropouts are prevalent occurrences on longitudinal study They are commonly dependent to the QoL of patients, that is, severe disease or death and called informative dropouts. Modelling the mechanism of dropouts could achieve the more accurate inference for survival analysis. A likelihood method is proposed to estimate the survival parameter and test the patterns of dropouts.

Purpose: This study aimed to investigate the mediating effects of health promotion behavior (HPB) in the relationship between anxiety and quality of life (QoL) in young adults living in the post-pandemic era. Methods: A cross-sectional descriptive online survey design was utilized. Data on anxiety, QoL, HPB, and demographic characteristics were collected from 213 adults aged 19-35 years in Korea via an online survey in January 2024. The collected data were analyzed using SPSS 27.0 and PROCESS MACRO 4.2 software. Results: Strong correlations were observed among anxiety, QoL, and post-pandemic HPB (PP-HPB) in young adults, and anxiety and PP-HPB were identified as significant predictors of QoL. The total effect of anxiety on QoL was significant (B = -1.40, bootstrapped SE = 0.10), with both the direct effect (B = -0.70, bootstrapped SE = 0.09) and the indirect effect (B = -0.70, bootstrapped SE = 0.11) being significant. This suggests that PP-HPB partially mediated the relationship between anxiety and QoL. Conclusion: This study highlights the importance of strengthening HPB with consideration of life changes since the coronavirus disease 2019 pandemic to improve QoL among young adults with anxiety.
