The purpose of this study was to examine the effects of the Mindfulness Meditation program on sleep, depression and quality of life in the institutionalized elderly women. The study was a nonequivalent control group pretest-posttest design. The data was collected from March 7 to April 25 of 2014. Participants in the study were 56 elderly women, 30 institutionalized elderly for the experimental group and 26 institutionalized elderly for the control group. The experimental group received the Mindfulness Meditation program for 90 minutes/session/week for 8 weeks. Data were analyzed using x2-test and t-test for subject homogeneity verification, and paired t-test to examine the hypotheses. Mindfulness Meditation program experimental group showed significant differences in sleep score(t=-4.406, p=<.001), quality of life score(t=-8.799, p=<.001). However no significant differences were found between 2 groups for the scores on depression. According to the results the Mindfulness Meditation program was useful for improving on sleep and quality of life in the institutionalized elderly women.

Objectives: This study aimed to investigate the effects of auricular acupressure on anxiety and sleep among patients undergoing chemotherapy for breast cancer. Methods: A nonequivalent control group nonsynchronized design was employed. The experimental group received auricular acupressure on specific acupoints (shenmen, heart, kidney, subcortex), and the control group received auricular acupressure on helix 1, helix 2, helix 3, and helix 4 three times a day for three weeks. A total of 60 women were divided into an experimental (n=30) and control (n=30) group. Patient recruitment occurred between May and August 2019. The collected data were analyzed by a chi-square test, paired t-test, and independent t-tests using the SPSS 21.0 program. Results: There was a significant decrease in anxiety(t=4.61, p=<.001) and increase in sleep(t=3.81, p=<.001) in the experimental group compared to the control group. Conclusions: The findings confirm that auricular acupressure is an effective nursing intervention to decrease anxiety felt by patients undergoing chemotherapy and to increase the quality of their sleep.

Purpose: The purpose of this study was to identify sleep patterns, alertness, and fatigue of shift nurses according to circadian types. Methods: The researchers' enrolled 17 nurses doing shift work in a tertiary hospital. To evaluate circadian types, a morningness-eveningness questionnaire (MEQ) was administered. Sleep patterns were examined using an actigraph for 14 days. To assess alertness and fatigue, Visual Analogue Scale (VAS) was used. The data were analyzed using ANOVA and Kruskal-Wallis test with a SPSS 21.0 program. Results: The researchers found that 17.6% of participants reported morning type, 47.1% neither type, and 35.3% evening type. Mean total sleep time (TST) was 6.8 h, mean sleep efficacy was 82%, level of alertness was 6.54, and level of fatigue was 5.49, regardless of the type of shift work. Evening type nurses had higher variation in TST and alertness, according to the shift patterns than other circadian type nurses. Evening type nurses also had higher fatigue levels than other circadian type nurses. Conclusion: Sleep, alertness, and fatigue were related with circadian types. These results suggest that circadian rhythm management in shift work nurses, particularly in evening type nurses is urgently needed to improve sleep patterns, alertness, and to decrease the level of fatigue.

Purpose: This study investigated the prevalence of hypertension, explored sleep duration, and examined the related factors to hypertension in Korean middle-aged adults. Methods: Using raw data from the Korean National Health and Nutritional Examination Survey (KNHANES) conducted from 2008 to 2010, a secondary analysis was performed with data from 13,230 adults aged 30~64 years. ${\chi}^2$-test and multiple logistic regressions was used for the data analysis. Results: The prevalence of hypertension among Korean middle-aged adults was 21.8% and 40.3% among participants reported that their average sleep duration was below six hours a night. Risk factors for hypertension include: female (the odds ratio (OR) 1.66 for male), 50~64 years age group (OR 3.66 for 30~49 years age group), education level of elementary school (OR 1.84 for university level), low household income (OR 1.27 for upper), obesity (OR 2.41), high risk drinking (OR 1.64), and sleep duration${\leq}6$ hrs (OR 1.16 for 8 hrs of sleep). Conclusion: High risk population of hypertension could be male, aged, low education, and low income. Obesity, high risk drinking, and short sleep duration should be considered as risk factors for hypertension. Interventions for obesity management, adequate alcohol drinking and sleep duration could be considered for preventing hypertension.

The prevalence of insomnia and the degree of impairment due to insomnia is greater than in the of young. The cause for insomnia in the elderly are various factors among the elderly is known to be high including medical, psychiatric, drug issues, circadian rhythm changes, sleep disorders, and psychosocial. So the careful evaluation to find the cause of insomnia is needed for the eldery. Treatment options for insomnia include behavior modification and pharmacotherapy. Outcome data from previous studies indicate that behavioral approaches produce reliable and durable therapeutic benefits, as evidenced by improved sleep efficiency and continuity and enhanced satisfaction with sleep patterns. Treatment methods such as stimulus control and sleep restriction, which target maladaptive sleep habits, are especially beneficial for older insomniacs, whereas relaxation-based interventions aimed at decreasing arousal, produce more limited effects. Cognitive and educational interventions are instrumental in altering age-related dysfunctional beliefs and attitudes about sleep. The choice of hypnotics is based on matching the nature of the insomnia to the hypnotic agent. The ideal agent has rapid onset, duration of action that lasts through the night but no residual daytime effects, and no adverse effects. The key for the healthcare professional is finding the appropriate treatment or treatment combination, including behavioral modification and pharmacotherapy. When hypnotics are indicated, the most appropriate short-acting agent should be considered.

The cyclic alternating pattern (CAP) is a periodic EEG activity in NREM sleep, characterized by sequences of transient electrocortical events that are distinct from background EEG activities. A CAP cycle consists of two periodic EEG features, phase A and subsequent phase B whose durations are 2-60 s. At least two consecutive CAP cycles are required to define a CAP sequence. The CAP phase A is a phasic EEG event, such as delta bursts, vertex sharp transients, K-complex sequences, polyphasic bursts, K-alpha, intermittent alpha, and arousals. Phase B is repetitive periods of background EEG activity. The absence of CAP more than 60 seconds or an isolated phase A is classified as non-CAP. Phase A activities can be classified into three subtypes (A1, A2, and A3), based on the amounts of high-voltage slow waves (EEG synchrony) and low-amplitude fast rhythms (EEG desynchrony). CAP rate, the percentage of CAP durations in NREM sleep is considered to be a physiologic marker of the NREM sleep instability. In insomnia, the frequent discrepancy between self-reports and polysomnographic findings could be attributed to subtle abnormalities in the sleep tracing, which are overlooked by the conventional scoring methods. The conventional scoring scheme has superiority in analysis of macrostructure of sleep but shows limited power in finding arousals and transient EEG events that are major component of microstructure of sleep. But, it has recently been found that a significant correlation exists between CAP rate and the subjective estimates of the sleep quality in insomniacs and sleep-improving treatments often reduce the amount of CAP. Thus, the extension of conventional sleep measures with the new CAP variables, which appear to be the more sensitive to sleep disturbance, may improve our knowledge on the diagnosis and management of insomnia.

Purpose: The study aimed to examine quality of sleep in hemodialysis patients and explore physical, physiological, and psychological factors determining sleep quality. Methods: The survey was conducted among 165 patients on maintenance hemodialysis at a university hospital. Data were collected from July to October in 2015. The sleep quality and its related factors were assessed by standardized questionnaires, anthropometric measures, and lab tests after obtaining a written consent from the participant. Results: The mean age of the participants was 62.58 years old, and 67.9% of the participants experienced sleep disorders such as 'not falling asleep within 30 minutes' or 'frequently waking up at night'. Pain (t=-3.29, p=.007) and depression (t=-6.028, p<.001) were significantly different between the group with sleep disorder and the other without. The demographic factors (age, shared room, sleep during the day), physical factors (pain and symptom), and psychological factors (depression and trait and status anxiety) together explained 20.0% of variance in sleep quality. Conclusion: Sleep disorder was frequently experienced among the patients on maintenance hemodialysis. The effective nursing strategies should focus on sleep environment, pain and depression management. Further study is warranted to explore the effect of physiological factors related to the disease on sleep disorder in this population.

Purpose : This study aimed to examine the relationship between sleep quality and its influencing factors in patients with coronary artery disease (CAD). Methods : This descriptive correlational study included 130 patients with CAD admitted to the cardiology department of a general hospital in B City between September 2019 and February 2020. Data were collected using structured questionnaires and research instruments to measure sleep quality, anxiety, depression, chronotype, and daytime sleepiness. Results : The mean scores for sleep quality, daytime sleepiness, anxiety, and depression were 7.59±3.45, 6.45±3.46, 6.58±3.88, and 7.74±4.05, respectively. In terms of chronotypes, 10.8%, 48.5%, and 40.7% of the participants had evening-, intermediate-, and morning-type patterns, respectively. Sleep quality was significantly correlated with anxiety (r=0.38, p<.001), depression (r=.37, p<.001), and daytime sleepiness (r=.26, p =.002). Factors associated with sleep quality in patients with CAD included anxiety (β=.29), heart failure (β=.22), daytime sleepiness(β=.21), and sleeping alone (β=.19). Collectively, these factors had an explanatory power of 23.1% for sleep quality variance. Conclusion: Patients with CAD often experience poor sleep quality owing to various factors such as anxiety, daytime sleepiness, heart failure, and sleeping alone. It is recommended that healthcare providers objectively evaluate sleep and identify factors that influence sleep quality. This will enable the development of effective methods for sleep management as part of nursing care.

Objectives: This study aims to identify the effect between high school students' recognition of mental health on sleep quality to present basic data for better health. Methods: The study used data obtained through the 2007 online research on adolescents' health behaviors, targeting a total of 35,228 high school students (18,628 of male students and 16,600 of female students). Results: Seventy six point ninety six percent of the male respondents and 79.67% of female respondents answered their sleep quality was not satisfactory. The subjects who had stress showed significantly lower quality of sleep than those who answered they had no stress. For female students, those who answered they had intention to suicide had significantly lower quality of sleep than those who answered they did not have, but for male students, there was no significant relations between them. There were no significant relations between sense of dispair and sleep quality both for male and female subjects. Conclusion: Factors of mental health related with sleep quality were stress and intention of suicide. The more they had stress and intention of suicide, the significantly lower sleep quality was. Therefore, in order to improve sleep quality of high school students, it is suggested that management programs based on education and counselling with experts should be provided and further studies on other mental health factors and sleep quality should be conducted.
