Objectives:The objective of this study was to examine the relationship between Sleep quality and Quality of life in medical college students. Methods:The participants of this study was 89 medical college students. They completed the Pittsburgh Sleep Quality Index, Epworth sleepiness scale, Stanford Sleepiness Scale, Quality of life scale. Results:Among respondents, 65.2% was male, 10 persons were smoker, total sleep time was 6 hour 30 minutes. There was statistically significant difference in daytime dysfunction between men and women in Pittsburgh Sleep quality index, and in factor Subjective Sleep Quality and factor Sleep Disturbance between normal BMI and obese BMI. Competence, psychological well-being, and stability factor in quality of life is significantly correlated with sleep disturbance factor in sleep quality, and physical well-being in quality of life is correlated with subjective sleep quality and sleep latency. School achievement was not significantly correlated with sleep quality. Conclusion:Poor sleeper experience poor quality of life than the other, especially psychological well-being, physical well-being, activity in quality of life. Therefore the authority must initiate the program that makes the medical college students take good nights.

김덕주 국제문화기술진흥원 2022 International Journal of Advanced Culture Technolo Vol.10 No.3

The purpose of this study is investigate the effects of quality of life and occupational performance on quality of sleep in college students. Data had been collected from Sep. 1 to Sep. 30, 2021. The subjects of this study were students majoring in occupational therapy at C College situated in C region. For analysis, 103 copies of questionnaire were used. As study instruments, a structured questionnaire incorporating questions about general characteristics, and measurement scales for quality of life, quality of sleep, and occupational performance evaluation were applied. Subjective sleep quality and sleep latency of study participants had lower scores than other components. According to the analysis on different quality of sleep depending on general characteristics, women had more sleep disturbances as they didn’t have any part-time job. In terms of the correlation between quality of sleep and quality of life, physical health and total score (quality of life) had correlations with daytime dysfunction. With regard to influential factors on quality of sleep, rest & sleep as a domain of occupational performance and work affected quality of sleep. Students’ quality of sleep will be improved if they keep regular habits of living, have rest appropriately for alleviating their stress, and do their jobs with interest and successfully according to a procedure. It is expected that the results of this study will be helpful to care for the health of would-be experts in charge of national health care.

Purpose/objective Understanding and determinants of health-related quality of life (HRQoL) and sleep hygiene among individuals with type 2 diabetes mellitus (T2DM) would be important to adapt and target health care resources to improve the health outcomes for the T2DM. To date, the relationship between HRQoL and sleep quality has not been reported in the Indian T2DM population. This study measured the relationship between sleep quality and HRQOL, in Indian population with T2DM. Methods A cross-sectional study, included a total of 300 patients with T2DM [Fig 1.]. All participants were responding to the Pittsburgh Sleep Quality Index (PSQI) and European Quality of Life-5 Dimensions Questionnaire (EQ-5D). A PSQI global score ≥5 was defined as poor sleep quality. EQ-5D visual analogue scale (VAS), determining the overall health status. Logistic regression analysis was used to examine the association between PSQI and EQ-5D. All data were analysed using the SPSS software version 20.0. Values of p <0.05 were considered statistically significant. Results The mean age of participants was 57.56. Majority of the participants (55.3%) were identified as “poor sleepers” and female (31.3%) contributing higher proportion. Positive correlation was found between, poor sleep quality and dimensions for EQ-5D [Table 1]. Poor sleepers had significantly lower the HRQoL (p < 0.001). After adjustment, poor sleep quality was significantly associated with a lower HRQoL; EQ-5D index (OR= 1.080, 95%, CI: 1.015 - 1.148, p < 0.05), and EQ-5D VAS (OR= 1.092, 95%, CI: 1.021 - 1.176, p < 0.01) [Table 2]. Overall the EQ-5D index and EQ-5D VAS were found to be an independent predictors of sleep quality. Conclusions Poor sleep quality is prevalent in Indian T2DM population, and it imparts negative impact on several dimensions of EQ-5D. Further real-world studies are needed to determine the causal relationship between T2DM patients and measure of objective sleep.

Objectives: Sleep quality is directly related to the health, quality of life and working capacity and is affected by age, gender, exercise, life habits. Gender dissimilarities in sleep quality are acknowledged. However, the gender difference in the quality of sleep in shift workers was not well known. Our aim was to study the less known gender differences in the quality of sleep of shift workers. Methods: 1,008 study subjects aged between 21 and 57 years among these, 637(525 male and 112 female workers) were daytime workers and 371(253 males and 118 female workers) were shift workers. Sleep quality was measured by self-report through the Pittsburg Sleep Quality Index(PSQI) and fatigue was measured by using the Chalder Fatigue Scale(CFS). All data was analyzed using SPSS version 19.0 program. The study was approved by the Institutional Review Board of the Occupational Safety and Health Research Institute. Results: Overall, sleep quality was found to be worse in shift workers than in daytime workers and in female than in male. Fatigue in shift female workers was significantly higher than in daytime female workers and shift male workers. In Spearman correlation analysis results, fatigue were significantly associated with gender, drink habit, regular exercise, working hours and sleep quality. With group male workers as the reference, the odds ratio(OR) for having a CFS was 2.115(β value=0.749, p<0.01), and subjective sleep quality, sleep latency, daytime dysfunction and PSQI were 1.541(β value=0.432, p<0.05), 2.297(β value=0.831, p<0.001), 1.798(β value=0.587, p<0.01) and 2.224(β value=0.799, p<0.01), respectively. Conclusions: Shift work played an important role in lowering the quality of sleep, and the effect was more pronounced in female workers than in male workers. Sleep quality was related to fatigue, especially sleep quality, sleep duration, sleep disturbances and daytime dysfunction were significantly related. Therefore, to improve fatigue and sleep quality of shift worker, it is necessary to improve healthy habits such as regular exercise, smoking cessation, and limited drinking. In particular, it is urgent to develop and implement a regular exercise program to reduce fatigue and improve the quality of sleep in workplace.

Objectives: Sleep disturbance in the elderly is associated with cognitive decline. Sleep quality is known to deteriorate with age, and prospective studies seldom have examined the relationship between sleep quality and cognitive function. This study investigates the relationship between early sleep quality and cognitive function based on six-year follow-up data of communi- ty individuals older than 60 years. Methods: The participants included 622 community elderly people older than 60 years from Jinju-Si. The final analysis com- prised 322 elderly people. Pittsburgh sleep quality index (PSQI) and the Korean version of Consortium to Establish a Registry for Alzheimer’s Disease (CERAD-K) were used to assess early sleep quality and cognitive function after six years. Multiple lin- ear regression analysis was performed to investigate the association between early sleep quality and cognitive function in the elderly. Results: Early sleep quality (PSQI) was significantly associated with the results of the digit span test, clock drawing test (clox 1), and word recall test after six years. Sleep quality (PSQI) decreased significantly after six years, and lower quality of sleep (PSQI) score was associated with higher digit span test score (β = -0.167, p = 0.026) and higher clock drawing test score (β = -0.157, p = 0.031). Lower quality of sleep (PSQI) score was associated with higher word recall test (β = -0.140, p = 0.039). Conclusion: The digit span test, word recall test, and clock drawing task (CLOX 1) shown to be significantly associated to sleep quality can be performed fast and easily in clinical practice. It is important to assess early cognitive function in the el- derly with poor sleep quality, and further studies could suggest that these tests may be useful screening tests for early de- mentia in elderly with poor sleep quality. 목 적:나이가 들수록 수면의 질은 나빠진다고 알려져 있으며 수면의 질과 인지기능 사이의 관계를 조사한 전향 적 연구는 현재까지 거의 없었다. 본 연구에서는 60세 이상 의 지역사회 노인을 대상으로 6년 동안 추적 조사한 자료를 바탕으로 초기 수면의 질과 인지기능 사이의 관련성을 알 아보고자 하였다. 방 법:본 연구에서는 60세 이상의 지역사회 노인 622명 을 대상으로 하였고 최종 분석에는 322명의 노인이 포함되 었다. 다음과 같은 임상척도가 사용되었다. 피츠버그 수면 질 척도(Pittsburgh sleep quality index, PSQI)와 한국판 신 경심리 평가집(Korean version of Consortium to Establish a Registry for Alzheimer’s Disease, CERAD-K). 초기 수 면의 질과 6년 이후의 인지기능의 관련성을 평가하기 위해 다중 선형 회귀분석을 시행하였다. 결 과:초기 수면의 질(PSQI)은 6년 이후의 숫자 외우기 검사(digit span test), 시계그리기 검사(CLOX 1), 단어 목 록 회상 검사(word recall test)의 결과와 유의한 관련성이 있었다. 수면의 질이 좋을수록(β = -0.167, p = 0.026) 숫자 외우기 검사 점수가 증가했으며 수면의 질이 좋을수록(β = -0.157, p = 0.031) 시계 그리기 점수(CLOX 1)가 증가했다. 또한 수면의 질이 좋을수록(β = -0.140, p = 0.039) 단어 목 록 회상 검사 점수(word recall test)가 증가했다. 결 론:본 연구에서 수면의 질과 유의한 관련성이 있는 나온 숫자외우기 검사(digit span test), 단어목록 회상 검사 (word list recall), 시계 그리기 검사 (CLOX 1)는 임상에서 비교적단시간내에간편하게수행할수있는검사이다.수 면의 질이 낮은 노인을 대상으로 이른 시기에 인지기능을 평가하는것은중요하며추후위의3가지검사가수면의질 이 낮은 노인에게 조기 치매 진단의 유용한 선별검사가 될 수 있음을 밝히는 연구가 더 진행되어야 할 것이다.

Objective: The sleep quality is worse in rheumatoid arthritis (RA) patients than in healthy controls and it is more difficult to achieve a satisfactory quality of life after treatment with age. Our aim is to assess the quality of life and sleep in elderly onset RA patients and to analyze the effect of disease-modifying agents on sleep and quality of life. Methods: Thirty-four older patients with RA patients and 30 healthy controls are included in the study. Sleep quality was evaluated with the Pittsburg sleep quality index and quality of life with Short Form-36. Parametric/non-parametric tests and Spearman/ Pearson correlation analysis were applied for the data according to the distribution. Results: While the rate of poor sleep quality before treatment was 67.6%, the rate was 26.5% after treatment. There was a statistically significant difference before and after treatment in terms of subjective sleep quality, sleep latency, sleep duration, sleep efficiency, and scores for sleep disturbance. The mean steroid dose and Disease Activity Score-28 were higher in patients with poor sleep quality than in patients with good sleep quality. Patients with poor sleep quality had lower mean physical function, pain, general health, social function, emotional role difficulties, and energy/vitality values than patients with good sleep quality. Conclusion: Both sleep and quality of life improved after treatment in older patients with RA patients. In older patients, it should be regularly evaluated in terms of sleep and quality of life and appropriate treatment should be provided.

The purpose of this study was to investigate the relationship between sleep quality and sleep duration according to individual characteristics, and the relationship between sleep quality and cold type. A total of 1998 participants aged 30-55 who participated in a community cohort study at KIOM's Oriental Medicine Data Center (KDC) was analyzed. Cold type was diagnosed with a common the Questionnaire of Cold Pattern Identification (8 items). Sleep quality was assessed by the Pittsburgh Sleep Quality Index. The participants in this study were classified into 1193 with cold type and 805 with non-cold type. The poor sleep quality was found in more women than men, and the Body Mass Index (BMI) was higher in the non-cold type. In the cold type group, average sleep quality was poor and sleep duration was short. There was a statistically significant correlation between cold score, sleep quality, and sleep duration. Cold type was related to the sleep quality. The risk of poor sleep quality increased 1.46 with increased cold type (95% CI = 1.16-1.84, p <.001). In particular, it was found that various programs to improve the quality of sleep, focusing on the cold type among personal characteristics, are needed to maintain adequate sleep to improve the sleep quality. In the future, when analyzing the relationship between cold type and sleep quality, it is thought that an attempt to derive other objective quantitative indicators is needed.

경북대학교 의학전문대학원 신경과학교실, 경북대학교 뇌과학연구소 , 경북대학교 의학전문대학원 신경과학교실초록 요약 Objectives: Sleep disorder is common in patients with neurodegenerative diseases. Several studies showed that sleep quality impacts on cognitive function, psychiatric symptoms, and quality of life. The purpose of this study is to evaluate the interrelations of quality of sleep, depressive symptoms, and quality of life in idiopathic Parkinson's disease (IPD). Methods: We enrolled 69 patients with IPD who had visited our clinic. IPD was diagnosed by UK Parkinson's Disease Society brain bank clinical diagnostic criteria. We assessed by Pittsburgh Sleep Quality Index (PSQI), Korean Mini-Mental State Examination (K-MMSE), Clinical Dementia Rating (CDR), Geriatric Depression Scale (GDS), and Short Form-36 (SF-36). Results: Poor sleep quality was defined by PSQI score 6 or above. Therefore, 36 patients (52.2%) of subjects had poor sleep quality. There were no significant differences in the demographics. The patients with poor sleep quality showed more cognitive dysfunction and depressive symptoms than those with good sleep quality. The PSQI scores significantly correlated with GDS and SF-36 scores. Also, quality of sleep exerted negative effect on quality of life and quality of life exerted negative effect on depressive symptoms. Conclusions: This study showed that there were significant interrelations among quality of sleep, depressive symptoms, and quality of life. Therefore, it is needed for evaluation and management of sleep disorders to improve quality of life in patients with IPD.

Background: Shift work and/or sleep quality may affect health. We investigated whether shift work and sleep quality, separately and jointly, were associated with abnormal levels of triglycerides, total cholesterol (TC), and low-and high-density lipoprotein cholesterol in 360 police officers (27.5% women). Methods: Triglycerides, TC, and high-density lipoprotein were analyzed on the Abbott Architect; lowdensity lipoprotein was calculated. Shift work was assessed using City of Buffalo payroll work history records. Sleep quality (good, < 5; intermediate, 6e8; poor, > 9) was assessed using the Pittsburgh Sleep Quality Index questionnaire. A shift work þ sleep quality variable was created: day plus good sleep; day plus poor sleep; afternoon/night plus good; and poor sleep quality. Mean values of lipid biomarkers were compared across categories of the exposures using analysis of variance/analysis of covariance. Results: Shift work was not significantly associated with lipids. However, as sleep quality worsened, mean levels of triglycerides and TC gradually increased but only among female officers (age- and raceadjusted p = 0.013 and 0.030, respectively). Age significantly modified the association between sleep quality and TC. Among officers > 40 years old, those reporting poor sleep quality had a significantly higher mean level of TC (202.9 ± 3.7 mg/dL) compared with those reporting good sleep quality (190.6 ± 4.0 mg/dL) (gender- and race-adjusted p = 0.010). Female officers who worked the day shift and also reported good sleep quality had the lowest mean level of TC compared with women in the other three categories (p = 0.014). Conclusion: Sleep quality and its combined influence with shift work may play a role in the alteration of some lipid measures.

We investigated whether shift work and sleep quality, separately and jointly, were associated with abnormal levels of triglycerides, total cholesterol (TC), and low-and high-density lipoprotein cholesterol in 360 police officers (27.5% women). Methods: Triglycerides, TC, and high-density lipoprotein were analyzed on the Abbott Architect; low-density lipoprotein was calculated. Shift work was assessed using City of Buffalo payroll work history records. Sleep quality (good, ${\leq}5$; intermediate, 6-8; poor, ${\geq}9$) was assessed using the Pittsburgh Sleep Quality Index questionnaire. A shift work + sleep quality variable was created: day plus good sleep; day plus poor sleep; afternoon/night plus good; and poor sleep quality. Mean values of lipid biomarkers were compared across categories of the exposures using analysis of variance/analysis of covariance. Results: Shift work was not significantly associated with lipids. However, as sleep quality worsened, mean levels of triglycerides and TC gradually increased but only among female officers (age- and race-adjusted p = 0.013 and 0.030, respectively). Age significantly modified the association between sleep quality and TC. Among officers ${\geq}40$ years old, those reporting poor sleep quality had a significantly higher mean level of TC ($202.9{\pm}3.7mg/dL$) compared with those reporting good sleep quality ($190.6{\pm}4.0mg/dL$) (gender- and race-adjusted p = 0.010). Female officers who worked the day shift and also reported good sleep quality had the lowest mean level of TC compared with women in the other three categories (p = 0.014).
