This study aimed to determine sleep disorders and associated risk factors in leukemia patients undergoing chemotherapy in Imam Khomeini Hospital of Sari, Iran. This cross-sectional study was conducted in 2015 with 100 patients selected. Inclusion criteria included complete mental and psychological health and being over 18 years old, and exclusion criteria included suffering other cancers, other chronic diseases, concurrent radiotherapy, and chemotherapy. The Pittsburgh Sleep Quality standard questionnaire was used to collect data. The questionnaire consisted of mental sleep quality, sleep latency, sleep duration, sleep quality, sleep disturbances, use of sleeping drugs, and impaired daily functioning. Data were analyzed by software SPSS 18 and by using descriptive and inferential tests (Pearson, Spearman, T-test and chi-square). Totals of 47 men (47%) and 53 women (53%) with a mean age of $44.1{\pm}1.7$, participated in the study. The mean overall score of sleep quality was $9.3{\pm}3.9$, which represents the average sleep quality in most participants. T-test shows that males have better sleep quality than females (t=2.1; 95%CI:0.004-0.25; P<0.01). Also the sleep quality increased with age (r=0.22, P=0.03). Results show that the amount of sleep quality was only moderate in most patients, so it is necessary to take coping strategies to improve their quality of sleep.

Purpose: Burning mouth syndrome (BMS) is ambiguous and enigmatic oral condition. Sleep disturbance is one of the most prevalent complaints of patients with chronic pain. The aim of this study was to estimate general sleep characteristics and propensity in patients with BMS. Methods: A total of thirty BMS patients and thirty healthy control subjects were investigated. Self-reported measures of sleep quality were conducted using two widely used methods; the Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). Data were analyzed with one-way ANOVA, chi-square, Fisher's exact test, Kruskal-Wallis test, Holm method with 95% confidence interval and p<0.05 significant level. Results: BMS patients showed more poor sleepers than those in control subjects in both ESS and PSQI test. BMS patients also showed statistically significant poorer sleep quality compared with control subjects in both test. When BMS group were divided into three groups on the basis of numeric rating scale, the higher score subjects had, the more mean rank they had in the PSQI. Conclusions: BMS patients showed up poor sleep characteristics and propensity than control group, and they also showed the more severe the pain was, the worse the sleep quality was.

Purpose: The purposes of this study were to (a) explore the prevalence of sleep patterns of middle-aged women; (b) identify the relationship between subjective sleep quality and its related variables; and (c) predict the possible explanations of how the related factors affect subjective sleep quality of middle-aged women. Methods: A total of 256 women aged 40-60 years were purposely sampled and given self-administered questionnaires in a cross-sectional, correlation coefficient design. The data was analysed using t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Results: The results were as follows; (a) a total of 40% of the women were poor sleepers as defined by a global PSQI score >5; (b) there were significant differences in quality of sleep related to type of family, number of present illnesses, and use of medication; (c) health promoting behaviors, family functioning, depression, and climacteric symptoms were significantly related to subjective sleep quality; and (d) 34% of variance in subjective sleep quality can be explained by climacteric symptoms, depression, type of family, and spouse. Conclusions: Our findings suggested a high proportion of poor sleeping in middle-aged women. Poor sleeping appeared to have poor health promoting behaviors, lower family functioning, worse depression, and higher climacteric symptoms. Climacteric symptoms, depression, type of family, and spouse were independent risk factors for poor sleeping. Nurse professionals should screen for sleep problems in middle-aged women with a biopsychosocial and behavioral aspect.

Objectives: We investigated whether sleep behaviors, severity of insomnia and circadian typology are associated with quality of life among Gyeongsang National University (GNU) medical students. Methods: Questionnaires were distributed to 46 fourth-year students of GNU Medical School. The hospital anxiety-depression scale, insomnia severity index (ISI), morningness-eveningness questionnaire (MEQ) and WHO Quality of Life-BREF (WHOQOL-BREF) were used. Results: Quality of life in terms of physical health was associated with age, weekday total sleep time (TST), weekend TST, catch up sleep, depression, ISI score, and MEQ score. Quality of life in terms of psychological health was correlated to weekday and weekend TST, anxiety, ISI score and MEQ score. Sex, weekday TST, depression, and ISI score were revealed to influence the social aspect of quality of life, and weekday and weekend TST, and ISI score were associated with quality of life in terms of environment. Multiple regression analysis showed that better sleep quality predicted to a higher quality of life in terms of physical, psychological and environmental health, and eveningness was associated with a better quality of life in terms of physical and psychological health. Conclusion: It is concluded that physical, psychological, and environmental aspects of quality of life were associated with quality of sleep and that physical and psychological aspects of quality of life were related to eveningness in GNU medical students. Therefore, it is equally important to treat emotional problem as well as improve sleep quality.

Purpose: The purpose of this study was to investigate the relationship among sleep quality, heart rate variability (HRV), fatigue, depression, and anxiety reported by Korean adults. Methods: A cross-sectional study of 208 adults aged 20~60 years was conducted using a short-term HRV analysis and self-reported questionnaires of Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale, Beck Depression Inventory, and State Trait Anxiety Inventory. Results: Subjects with good sleep quality (PSQI $score{\leq}5$) had higher HRV total power (t=2.03, p=.043) and high-frequency (t=2.04, p=.043) with lower fatigue (t=-4.08, p<.001), depressive mood (t=-3.66, p<.001), and trait anxiety (t=-3.84, p<.001) than subjects with poor sleep quality. Poor sleep quality was negatively correlated with HRV total power (r=-.17, p=.016), high-frequency (r=-.14, p=.049), and positively fatigue (r=.39, p<.001), depression (r=.44, p<.001), state anxiety (r=.23, p=.001) and trait anxiety (r=.34, p<.001). Conclusion: The results indicated that sleep quality is correlated with HRV which reflects the activities of the autonomic nerve system, fatigue, depression, and anxiety in adults.

Objective To determine the socio-demographic, psychologic, hematologic, or other relevant factors associated with hand grip strength in Korean farmers. Methods A total of 528 healthy Korean farmers were enrolled. Hand grip strength was measured in both hands using a hydraulic dynamometer. Socio-demographic characteristics were assessed and anthropometric measurements were obtained. Psycho-cognitive measurements such as sleep quality (Pittsburgh Sleep Quality Index) and Go/No-Go test response time were conducted. In addition to physical measurements, serologic parameters including insulin-like growth factor 1 were measured. The factors associated with hand grip strength were analyzed using multiple linear regression analysis after adjusting for age, height, and weight. Results The mean hand grip strength was associated with the Pittsburgh Sleep Quality Index total score (${\beta}=-0.12$, p=0.01), the Go/No-Go test response time (${\beta}=-0.18$, p=0.001), vitamin D (${\beta}=0.12$, p=0.02), and insulin-like growth factor 1 levels (${\beta}=0.1$, p=0.045). In female farmers, hand grip strength was only associated with the Pittsburgh Sleep Quality Index total score (${\beta}=-0.32$, p<0.001). Conclusion The results of this study demonstrate that hand grip strength was associated with sleep quality and attention in Korean farmers.

The purposes of this study were to identify the prevalence of fatigue. and factors influencing fatigue in women with rheumatoid arthritis. The subjects were 124 patients with rheumatoid arthritis. Most of all patients felt fatigue and mean score measured by Multidimensional Assessment of Fatigue was relatirely high. Fatigue was positively correlated with pain intensity, the number of pain sites, functional disability, depression. and sleep quality. A hierachical regression model was used to determine the variance which accounts for fatigue. Pain intensity, depression. sleep quality accounted for fatigue significantly. This finding indicates that pain influences fatigue through depression and sleep quality ; depression through sleep quality. The causative factors could be identified by further study of structural eqation model.
