Purpose: This study was done to compare sleep patterns, factors of sleep disturbance and sleep enhancement behaviors between sleep disturbance and non-sleep disturbance elderly patients. Method: The participants were 117 patients over 65 years old who were hospitalized at 5 general hospitals in Seoul. There were 83 patients in the good sleeper group and 34 in the poor sleeper group. The survey questionnaires included questions on general characteristics, sleep patterns, sleep disturbing factors, and sleep enhancement behaviors of the patients. Results: For sleep patterns and environmental factors of sleep disturbance, the poor sleepers was significantly higher than that of the good sleepers. Significant differences between good sleepers and poor sleepers were also found on the following variables: Environmental factors of sleep disturbance -'Sound of other patient's or care-giver's', 'Discomfort of bed, linen, pillow and patient's gown', 'Light in the room', 'Emergency situations', 'Temperature of patients rooms too hot or too cold'. The significant physical factor of sleep disturbance was 'Hard to breath even without moving' and for sleep enhancement behaviors: 'Use of ear plugs or eye covers' Conclusion: Consequently it is necessary to develop positive and differentiated programs for sleep enhancement for the inactive and poor sleeper among the elderly patients.

The World Health Organization(WHO) has recommended population of sleep disturbance as one of the environmental health indicators. But the percentage of respondents who felt highly sleep disturbed, that is, %HSD can???thave application to sleep disturbance from instantaneous noise. Therefore, this study has been carried out to present the technique for assessing sleep disturbance on instantaneous noise quantitatively. The study of sleep disturbance on night time instantaneous railway noise has been undertaken. Noise monitor has been in operation from 22 hours to 7 hours during 6 nights at 12 locations. To assess instantaneous noise induced sleep disturbance, it was decided to measure body movement by actiwatch. %motility was used as indicators of sleep disturbance. %motility is the expected value of probability of motility value during 7 epochs (105s) of any noise event. The measures of instantaneous motility have been related to measures of instantaneous railway noise events. The relationship shows that %motility is a good predictor for assessing sleep disturbance and Korean is more sensitive to noise than European although the railway noise have been considered in this study. This study can be extended to assessing long-term sleep disturbance and give a guideline far policy decision.

Purpose : This study aims to investigate the differences in fatigue, sleepiness, and near-miss according to sleep disturbance among shift nurses in intensive care units (ICUs). Methods : A cross-sectional study in a tertiary hospital was performed. A total of 122 shift nurses working in the six ICUs were recruited. They completed self-reported questionnaires about sleep disturbance, fatigue, sleepiness, and near-miss in the past two weeks. Results : The prevalence of reported sleep disturbance was 30.3% (37 out of 122 subjects). Compared to the non-sleep disturbance group, the sleep disturbance group reported significantly more sleepiness (11.46 vs. 8.86) and higher fatigue (82.62 vs. 69.39). The sleep disturbance group showed higher rates of near-miss (78.4 vs. 57.6%) and a higher frequency of them (4.49 vs. 2.11/2weeks) compared to the non-sleep disturbance group. Medication error was the most common type of near-miss. Conclusions : This study suggests that sleep disturbances could increase fatigue, sleepiness, and near-miss among ICU shift nurses. Personal and organizational programs should be developed to support the sleep of ICU nurses.

Purpose: This study aimed to explore the knowledge and performance of sleep hygiene among nurses with shift work schedules and examine the influence on sleep disturbance. Methods: A total of 199 shift-work nurses from a tertiary hospital were included in the study. To examine the knowledge and performance of sleep hygiene, the participants were asked to respond to a self-reported survey. To assess sleep disturbance, the General Sleep Disturbance Scale was used. Descriptive statistics and multiple linear regression were applied using the SPSS/WIN 21.0 program to analyze the data. Results: Both the knowledge and performance of sleep hygiene among nurses with shift work schedules were measured at a moderate level. Nurses' knowledge and the performance of sleep hygiene was not significantly associated with sleep disturbance, whereas age, experience with shift-working, and perceived health status were significantly associated. Conclusion: Strategies for providing more accurate information and motivating better sleep hygiene would help to enhance sleep hygiene in nurses with shift work schedules. Further studies examining the association of knowledge and the performance of sleep hygiene with sleep disturbances in nurses with shift work schedules are needed.

Purpose: This study was done to investigate clinical characteristics and risk factors for sleep disturbance in patients with prostate cancer. Method: Participants were recruited from P hospital outpatient clinic from March 23 to April 20, 2006, and 101 participants completed a questionnaire assessing general and clinical characteristics, sleep quality, physical symptoms and psychological symptoms such as anxiety and depression. The data was analyzed using the SPSS 12.0 program. Results: In this study, 29.7% of the patients reported sleep disturbance. Cancer diagnosis related factors which affected sleep disturbance were onset (55.3%) and aggravation (83.3%). Habitual sleep efficiency of patients with sleep disturbance was as follows: bedtime was 10 PM, wake-up time was 6AM, sleep duration was six hours and twenty minutes. Risk factors for the presence of sleep disturbance included metastasis, the presence of intestinal symptoms, depression and anxiety. Conclusion: Sleep disturbance is a frequent problem associated with prostate cancer and seems to be influenced by aggravation of illness and the presence of physical and psychological symptoms.

Purpose: This study was conducted to test whether sleep disturbance mediates the effect of pain on fatigue, whether fatigue mediates the effect of pain on depression, and whether fatigue mediates the effect of sleep disturbance on depression. Methods: This study was conducted from September 12th to December 20th, 2011. One hundred eighty-eight breast cancer patients were recruited from D city and S city in Korea. The instruments used in this study were the pain, sleep disturbance, fatigue, and depression scales. Data were analyzed using descriptive statistics, Pearson correlation coefficients, and mediation pathway with the SPSS 12.0 and AMOS 20.0 programs. Results: There was correlation among pain, fatigue, sleep disturbance, and depression. Mediation analyses indicated that pain influences fatigue. sleep disturbance, and depression directly as well as indirectly. Sleep disturbance influences fatigue and depression directly, also fatigue influences depression directly. But sleep disturbance had no direct effect on depression. Conclusion: Significant correlations among the four symptoms supported the existence of the symptom cluster. Effects of pain on fatigue was partially mediated by sleep disturbance, also effects of pain on depression was partially mediated by fatigue. However, the effects of sleep disturbance on depression was fully mediated by fatigue.

Purpose: The purpose of this study was to assess pain, sleep disturbance, fatigue, and the quality of life and to identify the impact of pain, sleep disturbance and fatigue on the quality of life in patients with pancreatic cancer undergoing chemotherapy. Methods: Data were collected from June to July, 2010. Participants were recruited from Y university hospital in Seoul. Research instruments included numeric rating scale for pain, Functional Assessment Chronic Illness Therapy-Functional Well-Being (FACIT-FWB): General Factor 5 (GF5) for sleep disturbance, Functional Assessment of Cancer Therapy-General (FACT-G) for quality of life, and FACT-Fatigue for fatigue. Results: The quality of life for cancer patients had a significant relationship with pain, sleep disturbance, and fatigue. The significant factors influencing quality of life were pain, sleep disturbance, and fatigue that explained 52.6% of the variance. Conclusion: Patients with pancreatic cancer undergoing chemotherapy experienced pain, fatigue, and sleep disturbance which led to a negative effect on quality of life. The results suggest that intervention program to improve quality of life could reduce pain, fatigue, and sleep disturbance of pancreatic cancer patients undergoing chemotherapy.

Purpose: The objective of this study was to investigate the relationship between fatigue, sleep disturbance, and gestational stress in women during late stage of pregnancy. Methods: This study was conducted with 113 healthy pregnant women at gestational age greater than 27 weeks who were registered at community health centers and received prenatal care. A structured questionnaire regarding fatigue, sleep disturbance, and gestational stress was used. The data was analyzed using a t-test, an ANOVA, and Pearson correlation coefficients. Results: The subjects with unplanned pregnancies and irregular exercise patterns showed a higher level of fatigue than those with planned pregnancies and regular exercise patterns. Pregnant women with caffeine intake manifested higher levels of gestational stress and sleep disturbance than those without. The levels of sleep disturbance and gestational stress increased as the fatigue levels increased. The fatigue levels increased with increased levels of sleep disturbance. Conclusion: Planned pregnancy, regular exercise patterns, and caffeine intake were related with fatigue, sleep disturbance, and gestational stress in women during late stages of pregnancy. Fatigue, sleep disturbance, and gestational stress had close associations to each other. In the future, such results should guide development of nursing intervention programs for women in late stages of pregnancy.

Purpose. The purpose of this study was to identify the factors affecting quality of sleep and sleep disturbance among inpatient. Methods. A descriptive correlational study was conducted Participants were 200 inpatient in a hospital located in B city. A structured questionnaire was used for data collection. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and stepwise multiple regression. Result. Hospitalized patient's score of sleeping quality was 38.26 on an overall scale of 60, indicating it to be higher than 'Medium (30 points). Almost hospitalized patient in this study suffer from sleep disturbances. As results of univariate analyses, Educational level, Departments, Why hospitalized, Insomnia / depression, Chronic Disease, Scale of pain, physical symptoms, environmental factors, emotional factors, and sleep promoting behavior, disturbed sleep among hospitalized. However, the result of stepwise multiple regression analysis identified that physical symptoms, environmental factors, emotional factors, sleep promoting behavior, and Why hospitalized disturbed sleep and were significant score of sleeping quality for hospitalized and these sleep disturbance factors accounted 46.8% of variance of sleeping quality among hospitalized. Conclusion. These findings suggest that hospitalized patients with poor sleep quality should have their health carefully screened for physical symptoms, environmental factors, emotional factors, sleep promoting behavior, and why hospitalized. In addition, we recommend the development of a nursing program for improving sleep quality.

Purpose: The purpose of this study was to investigate factors of sleep disturbance and sleep patterns of elderly hospitalized women patients between young-old (65-74 years), old (76-84 years) and old-old (85 years and above). Methods: The questionnaire included the environmental disturbance factors (Paik, 2000), degree of pain (Wang & Kim,1995), disease symptoms (Paik, 2000), depression (Kee, 1996) and sleep patterns (Oh, Song, & Kim, 1998). Data were analyzed using frequencies, means, ${\chi}^2$-test, t-test, ANOVA, Scheffe, Pearson correlation coefficients and multiple regression (SPSS 14.0). Results: The middle, and oldest group's environmental disturbance factors of degree of pain, disease symptoms, depression and sleep patterns were higher than those of the younger group. The younger, middle, and oldest group's sleep pattern had a significant negative correlation with environmental disturbance factors, degree of pain, disease symptoms and depression. The model including variables related to environmental, physical and psychological disturbance factors, explained the following variances in sleep pattern: 26.8% for the youngest group, 27.6% for the middle group and 40.7% for the oldest group. Conclusion: The result of this study offer basic data for the development of nursing intervention programs to improve sleep patterns for hospitalized women patients according to age differences.
