Full textAbstract:
Sleep disorders are one of the most common medical complaints today. There is a growing interest in sleep medicine, attitude of doctors and society is changing and knowledge about sleep and its disorders is increasing. One of the most tedious and understudied sleep problems is non-restorative sleep.
Researchers are still debating about what determines persons rest sense after the sleep. A lot of attention recently is paid for sleep integrity and a role of sleep fragmentation for the rest sense. It is thought that sleep fragmentation with short arousals could have effect on the sleeps restorative function.
The aim of our study was to analyze sleep structure and sleep quality through sleep cycles, phases and stages and to evaluate structure’s relationship with subjective sense of rest after the sleep without paying attention to the type of insomnia. We have analysed three types of arousals (behavioural, vegetative and microarousals) and their dynamics during the night, in different sleep cycles and stages. Subjective sleep quality was evaluated using the Pittsburgh sleep quality index.
Work results showed that for the subjective sense of rest after the sleep it is more important the stability of sleep in the initial than in the last sleep cycles. Sleep stage and arousal type regardless of sleep cycle are significant factors for the arousal index values and that increase of all arousal indices in NREM 2 stage (especially increase of microarousal index) has strongest impact for...

Paskutiniu metu miego medicina domimasi vis labiau, keičiasi gydytojų ir visuomenės supratimas apie miegą, jo sutrikimus, ligas ir negalavimus, susijusius su miegu. Vienas iš svarbesnių ir labai varginančių sutrikimų yra miegas be poilsio jausmo. Mokslininkai iki šiol diskutuoja, kas lemia poilsio jausmą po miego. Pastaruoju metu nemažai dėmesio skiriama miego vientisumo ir suskaldymo reikšmės poilsio jausmui tyrimams. Manoma, kad miego fragmentacija – miego suskaidymas dažnais trumpais nubudimais – mažina jo atstatomąją vertę, ypač smegenims. Pagrindinis darbo tikslas buvo išnagrinėti miego struktūrą ir kokybę per miego ciklus, fazes ir stadijas bei įvertinti miego struktūros ryšį su poilsio jausmu po miego nepriklausomai nuo nemigos tipo. Buvo nagrinėjami trijų tipų – elgesiniai, vegetaciniai ir žieviniai mikro – nubudimai ir jų dinamika nakties metu, skirtinguose miego cikluose ir stadijose. Subjektyviai vertinama miego kokybė buvo analizuojama pasitelkus Pitsburgo miego kokybės indeksą. Darbo rezultatai parodė, kad miego stabilumas nakties pradžioje turi didesnę įtaką subjektyviam miego kokybės jausmui negu miegas nakties pabaigoje. Nubudimų indekso dydžiui reikšmingos įtakos turi miego stadija ir nubudimo tipas, nepriklausomai nuo miego ciklo, o didžiausią įtaką poilsio jausmui turi visų tipų nubudimų, ypač žievinių mikronubudimų, indeksų padidėjimas antroje lėtojo miego stadijoje.

Kucharczyk, Erica. "The occupational impact of sleep quality." Thesis, Loughborough University, 2013. https://dspace.lboro.ac.uk/2134/11336.
Full textAbstract:
While the importance of assessing the occupational consequences of insomnia and other sleep disorders is emphasised in clinical nosologies and research guidelines, there is little consensus on which aspects of occupational performance should be assessed, how such impairment should be measured, and how outcomes should be reported. The research programme described in this thesis aimed to address this issue. Chapter 1 presents a systematic review and methodical critique of studies reporting those aspects of occupational performance most impacted by (or most frequently associated with) insomnia symptoms and degraded sleep quality. Equivocal results, wide variations in reporting conventions, and the overall lack of comparability among studies, strongly indicated the need to develop a standardised metric able to quantify sleep related occupational performance and serve as an assessment and outcome instrument suitable for use in research and clinical settings. Informed by the literature review, Chapters 2-4 describe the development and validation of the Loughborough Occupational Impact of Sleep Scale ( LOISS ), a unidimensional 19 item questionnaire that captures sleep-related occupational impairment across a number of workplace domains over a 4-week reference period. Chapters 5-7 describe LOISS outcomes from: i) surveys in a random population sample; ii) a representative sample of the UK workforce; and iii) a clinical sample of patients with obstructive sleep apnoea (before and after treatment with CPAP). Overall, the scale showed strong internal consistency (Cronbach s alpha range=0.84-0.94) and test-retest reliability (r=0.77, r2=0.59, p<0.001), high levels of criterion validity (significantly discriminating between good and poor sleepers), and proved an effective outcome measure in OSA. From the survey data reported in Chapters 2-7, LOISS score distributions showed no consistent gender difference but did show a significant ageing gradient, with sleep-related occupational impairment declining with increasing age. In conclusion, the work presented here supports the usability, validity and reliability of the LOISS as an assessment and outcome instrument, and also demonstrates the utility of this instrument in exploring the dynamics of sleep-related occupational performance

Full textAbstract:
Self-report retrospective estimates of sleep behaviors are not as accurate as prospective estimates from sleep diaries, but are more practical for epidemiological studies. Therefore, it is important to evaluate the validity of retrospective measures and improve upon them. The current study compared sleep diaries to two self-report retrospective measures of sleep, the commonly used Pittsburgh Sleep Quality Index (PSQI) and a newly developed sleep questionnaire (SQ), which assessed weekday and weekend sleep separately. It was hypothesized that the new measure would be more accurate than the PSQI because it accounts for variability in sleep throughout the week. The relative accuracy of the PSQI and SQ in obtaining estimates of total sleep time (TST), sleep efficiency (SE), and sleep onset latency (SOL) was examined by comparing their mean differences from, and correlations with, estimates obtained by the sleep diaries. Correlations of the PSQI and SQ with the sleep diaries were moderate, with the SQ having significantly stronger correlations on the parameters of TST, SE, and sleep quality ratings. The SQ also had significantly smaller mean differences from sleep diaries on SOL and SE. The overall pattern of results indicated that the SQ performs better than the PSQI when compared to sleep diaries.

Dopp, Austin. "Relative Effects of Sleep Hygiene Behavior and Physical Exercise on Sleep Quality." DigitalCommons@USU, 2017. http://digitalcommons.usu.edu/etd/6837.
Full textAbstract:
Numerous studies have shown the relationship between sleep and overall health. A common measure of sleep is sleep quality which has been shown to be influenced by a variety of factors such as physical activity, diet, stress, social engagement, cognitive stimulating, and sleep hygiene behaviors. Data was analyzed from a previous study to determine whether trying to change one’s sleep would improve sleep quality and if this was more effective than physical exercise. A group of 104 individuals, randomized to the treatment group, were asked to log their daily activities, via smartphone app, within these six behavioral domains for six months. Behavioral change scores were computed as the difference between six-month behavioral level and baseline behavioral level, for each of the six domains. Factor analysis that revealed that two latent factors explained the majority of the variance in behavioral change, with a "Physical Body Related behavior change” factor ("Physical") and a "Mental/Emotional" behavior change factor ("Mental"). In linear regression models, Physical significantly predicted sleep quality improvement over the six months (p=.029), but Mental did not (p=.606). In the middle aged adults in this study, the behavioral change pattern of increasing diet quality and physical activity, significantly predicted improvements in sleep quality. While efforts to improve one's cognitive and emotional well-being were not found to predict to sleep improvement, they still may be important for cognitive health overall. This information can prove useful as different interventions and programs are implemented to improve sleep in the population.

Kushkituah, Yudyahn. "Subjective Sleep Quality of Isolated Sleep Paralysis: Fear Parameters and Psychosocial Correlates." ScholarWorks, 2019. https://scholarworks.waldenu.edu/dissertations/6449.
Full textAbstract:
The bidirectional link between insufficient sleep and the distress related to a parasomnia known as isolated sleep paralysis (ISP) might lead to chronic health effects. The impact of fear-ridden hallucinations related to this REM sleep disorder can be both distressful and embarrassing for individuals often resulting in a reticence to seek help. This quantitative study was guided by a biopsychosocial approach with an integrated theoretical framework. One aim of the study was to determine if fear parameters of ISP (low and high) differ when considering psychosocial factors and sleep quality, based on the Dysfunctional Beliefs and Attitudes About Sleep Scale, the Social Phobia Inventory, the Locus of Control (LOC) subscales, and the Pittsburg Sleep Quality Inventory. Predictive associations between psychosocial factors and subjective sleep quality (SSQ) were also investigated. Retrospective online data from a sample of 159 participants ages 18 and over were analyzed via MANOVA, multiple regression, and independent samples t-tests. Findings from the MANOVA were significant and showed that participants who experience ISP with more fear scored higher on two measures, external other LOC and social phobia. The MANOVA regarding differences in SSQ in relation to psychosocial variables were not significant, and independent sample t-tests did not differentiate fear parameters for DBAS and SSQ (poor sleep was found for both parameters). Providers of therapeutic treatments should take factors of social phobia and external other LOC into account with regards to poor sleep quality for those distressed by ISP. Sleep quality assessments might benefit those who are afraid to disclose about ISP sleep distress, as long term poor sleep can place some at risk for negative health outcomes.

Full textAbstract:
Sleep has been shown to be associated with the sympathetic and parasympathetic branches of the autonomic nervous system at rest and during stress. However, sleep has not been examined in the context of sympathovagal balance (the coupled relationship between the sympathetic and parasympathetic nervous systems) during stress. The current study investigated whether sleep quality was associated with sympathovagal activity and reactivity to stress. Female participants (N=59) underwent a psychosocial stress task and completed the Pittsburgh Sleep Quality Index while EKG and ICG data were collected. Sleep quality was associated with pre-ejection period at rest and during stress, ps<.05, but was not associated with high-frequency heart rate variability or with sympathovagal reactivity, ps>.05. These findings suggest that sympathetic activity and reactivity account for a significant amount of variance in the relationship between sleep and the autonomic nervous system.

Full textAbstract:
Introduction: Type 2 Diabetes (T2DM) and sleep-related disorders share common risk factors such as obesity; but the interrelationships between T2DM and sleep disorders are not well examined. Aims: In this thesis I aimed to assess: 1. The longitudinal impact of obstructive sleep apnoea (OSA) on micro vascular complications in patient with T2DM. 2. The relationship between sleep quality, sleep duration and adiposity in patients with T2DM Methods: To examine the first aim, I utilized the data collected from a previous project that examined the cross-sectional associations between OSA and micro vascular complications in patients with T2DM and followed up the study participants longitudinally using 1-2-1 interviews and electronic health records. For aim 2, I conducted a crosssectional study in patients with young-onset T2DM who were recruited from Heart of England NHS Foundation Trust and primary care. Result: For Aim 1: Depending on the micro vascular outcome examined, we had approximately 200 patients in the analysis. Patients were followed up for 2.5 years for renal outcomes, and 4-4.5 years for retinopathy and neuropathy outcomes. The prevalence of OSA was 63%. I found that baseline OSA was significantly associated with greater decline of eGFR and greater progression to pre-proliferative and proliferative retinopathy. I also found that OSA was associated with progression to a combined outcome of foot insensitivity or diabetic foot ulceration but this was a non-significant trend (p=0.06). In addition, I found that patients who received and were compliant with continuous positive airway pressure (CPAP) treatment (delivered during routine care) had improvements in heart rate variability parameters by study end. For Aim 2: Poor sleep quality and shorter sleep duration were associated with increased total body fat% after adjustment for potential confounders. Conclusion: I found that OSA plays an important role in the progression of micro vascular complications in patients with T2DM. Whether treatment with CPAP has a favourable impact on micro vascular complications is currently being examined in a randomized controlled trial. I also found that sleep duration and quality are associated with increased adiposity. The direction of this relationship need to be examined in longitudinal studies and interventional trials.

Magee, Christopher. "The relationship between chronic sleep restriction, poor sleep quality and obesity in adults." School of Psychology, 2008. http://ro.uow.edu.au/theses/99.
Full textAbstract:
This thesis consists of two literature reviews followed by three empirical chapters that examined the relationship between chronic sleep restriction and obesity. Chapter 2 reviewed available research data and presented a theoretical model linking chronic sleep restriction to obesity. This model hypothesises that chronic sleep restriction contributes to obesity by altering energy regulatory hormones such as ghrelin and leptin. It was also argued that factors such as poor mental health, medication use and long work hours contribute to chronic sleep restriction at a population level, and could have implications for improving sleep. This model provides a sound theoretical framework, which was used to guide the subsequent empirical chapters. In chapter 3, the key methodological limitations of previous studies examining the relationship between chronic sleep restriction and obesity were outlined. Methodological recommendations for future research were then provided to facilitate a more complete understanding of how chronic sleep restriction and obesity are linked in the general population. Chapter 4 tested a path model linking chronic sleep restriction to obesity in 325 adults aged 18 to 87 years, based on the theoretical framework provided in chapter 2 and the methodological recommendations listed in chapter 3. The results indicated that short sleep durations and age were associated with obesity, whilst age, uncomfortable sleep environments, irregular sleep/wake cycles and poor mental health were associated with short sleep durations. However, the results also identified potential environmental, behavioural and psychological determinants of chronic sleep restriction that could be targeted in the future treatment and prevention of obesity. Chapter 5 examined the relationship between three dimensions of sleep quality as assessed by the Pittsburgh Sleep Quality Index and obesity in 262 adults aged 18 to 35 years. Short sleep durations and increased levels of daytime dysfunction (e.g., sleepiness) were associated with obesity, whilst irregular bedtimes, noisy environments, discomfort and depression were the major factors associated with poor sleep quality. These factors could play a role in obesity interventions that target sleeping patterns and need to be further investigated. Finally, chapter 6 examined the effects of two nights of seep restriction on energy expenditure and neuroendocrine hormones involved in energy balance regulation in ten healthy male adults. The results indicated that sleep restriction led to an increase in ghrelin and a reduction in PYY, which corresponded with increased hunger and reduced satiety. The results also suggested that energy expenditure declined with sleep restriction. These results suggest that sleep restriction could contribute to obesity by altering energy expenditure and the hormonal regulation of food intake. The findings from this thesis therefore suggest that chronic sleep restriction contributes to the development of obesity by altering key pathways identified in chapter 2. The identification of possible determinants of chronic sleep restriction has potential applications for the treatment and prevention of obesity. For example, the factors identified in chapters 4 and 5 could be targeted as a way to promote healthy sleep durations, and could be effective in improving the efficacy of existing interventions for obesity.

Full textAbstract:
Whereas sleep is often thought of as a common health issue among college students, few, if any, researchers have comprehensively evaluated correlates and predictors of sleep quality and quantity within this population. Most often, studies of this type are used by researchers to assess particular categories of correlates and predictors (e.g., emotional and mental health, student employment, substance abuse, etc.). The present study was conducted to determine correlates and predictors of sleep quantity and quality using among randomly selected college students at a Midwestern four-year research university with high research activity. A classroom survey comprised of the Pittsburgh Sleep Quality Index, the Medical Outcomes Study - Short Form 36, a sleep journal, and demographic questions was administered to students enrolled in 18 University Core Curriculum classes during the spring 2011 semester. Four hundred and sixty student surveys were used for data analysis. Average weekday sleep length was found to be statistically significantly correlated only with mental wellbeing. No statistically significant correlations were found between any of the potential predictor variables and the dependent variables of average weekend day sleep length. Overall sleep quality was found to be statistically significantly correlated with mental and physical wellbeing. Using path analysis, three reduced models, one for each of the three dependent variables (weekday sleep length, weekend day sleep length, and overall sleep quality, were produced. Through ×2 testing, reduced models for all three models fit the full model's data; deleted paths did not contribute to the model. As a whole, students are getting adequate sleep length, but possess poor sleep quality. Sleep quality and sleep quantity, are influenced by different factors, creating challenges for those wishing to provide education, prevention and intervention services.

Full textAbstract:
Type 2 diabetes has reached epidemic proportions globally, and accumulating evidence suggests extremes of sleep duration increase risk. Diet may be an important mechanism, yet few studies examine prospective relationships of sleep duration and diet quality or whether diet explains associations of sleep duration with childhood obesity or diabetes in adults. In Chapter One, we report a moderate correlation between self-reported sleep duration and actigraphy in Sueño, the sleep ancillary study to the Hispanic Community Health Study/Study of Latinos. Chapter Two identifies associations of chronic insufficient sleep duration since infancy with lower diet quality in mid-childhood in Project Viva: children with the least favorable diet and sleep have the highest body mass index z-scores in mid-childhood, but diet does not explain associations with adiposity. In Chapter Three, adherence to healthful dietary patterns reduces risk of diabetes in the Women’s Health Initiative; high quality diets are protective in all groups, but race/ethnicity modifies associations. In Chapter Four, we find that changes in sleep duration, increases in particular , are associated with diabetes and concomitant changes in diet quality, physical activity and weight in the Nurses’ Health Study. Each of these studies contributes new knowledge: Sueño represents the largest sleep validation to date, the only validation among Hispanic/Latinos and allows researchers to better understand the information contained in (and the limitations of) self-reported measures of sleep duration within subgroups. In the Women’s Health Initiative, we address limitations of the current literature on dietary patterns by calculating four dietary indices within the same cohort, standardizing the scores for comparison and examining associations across racial/ethnic groups. Project Viva is the first study to examine the influence of chronic insufficient sleep on diet quality in childhood when health behaviors and dietary preferences are being formed. Finally, examining changes in sleep duration and changes in diet quality, physical activity and weight in the Nurses’ Health Study represents a novel way to leverage repeated assessments. Results of this dissertation may help build the case for policy and intervention efforts to prevent and treat obesity and diabetes, particularly those that seek to improve both sleep and diet.<br>Nutrition

Full textAbstract:
The purpose of this study was to evaluate the use of earplugs to improve perceived sleep quality in hospitalized patients. Sleep disruption is a common problem for hospitalized patients and has been shown to lead to physical and emotional complications. A variety of factors such as pain, illness, stress, worry, noise, lights and patient care activities contribute to disturbed sleep. Studies on sound in hospitals have shown that levels exceed recommendations by the Environmental Protection Agency. Limited research has shown that earplugs are a cost-effective, nonpharmacologic intervention with clinical usefulness to improve sleep quality. The study design was a quasi-experimental pilot study using a pre-test and post-test with the participants serving as their own control. Participants were recruited from a telemetry unit at St. Vincent Healthcare in Billings, Montana. The Verran and Snyder-Halpern Sleep Scales were selected to measure sleep quality. Ten participants were able to complete the two nights of study. The proposed hypothesis was supported for the sleep characteristic, soundness of sleep, with an improvement greater than 15 mm on the night with the ear plugs. Subjective findings identified positive comments with only one participant unable to tolerate the earplugs. The improvement in sleep was clinically significant for these participants. Hospitals should consider creating a sleep promotion policy and re-evaluating their night care practices. Earplugs could be included as an option for patients, and patients experiencing sleep difficulties should be encouraged to try earplugs. Further research is needed with a variety of populations and a large sample size. Research should also be done on nurses\' knowledge and beliefs regarding sleep and sleep interventions. This information could provide useful information on areas where additional education is needed.

Full textAbstract:
This study explored the cognitive performance of poor and good sleepers in college students and older adults including inhibition, sustained attention, processing speed, spatial ability, attention set shifting, short term and working memory. Demographic measures, health measures, the Pittsburgh Sleep Quality Index, the Sleep Self-Efficacy scale, WAIS III Block Design and Digit Span, Trail Making Test Part A and B, psychomotor Vigilance Task, and the Multisource Interference task were given to participants. Sleep group accounted for the variance in cognitive performance even after controlling for education, depression, health, and age in the older adults. Age differences were not observed in sleep self-efficacy but were observed for self-reported sleep quality and cognitive performance. Sleep onset latency was a significant predictor of cognitive performance in older adults and sleep duration was significant for college students. Implications of the study include accidents, academic performance, and mental well-being as a result of cognitive deficit due to sleep loss.

Full textAbstract:
<p> The effect of workplace stressors on physical health has been well documented (Ganster & Rosen, 2013; Nixon, Mazzola, Bauer, Krueger, & Spector, 2011). However, gaps in the research led to two main goals of the study: (1) understanding in a fuller range of reactions through the study of justice adherence and rule infraction and (2) exploring an explanation for the justice-health effects. This multilevel, daily diary study was designed to measure participants’ perceptions of organizational fairness and physical health. After that participants responded to daily surveys on the perceived supervisor interactions, emotions, rumination, and sleep quality over the course of five days. A total of 157 participants were included, which provided 618 daily surveys. Results provide evidence for a relationship between person-level perceptions of distributive justice and procedural justice and injustice with daily sleep quality. Further, person-level distributive and procedural justice predicted daily fluctuations of happiness. Finally, indicators of rumination, measured daily, also predicted daily sleep quality. These findings suggest a need to continue exploring the full spectrum of fairness as the relationships across dimensions were different across health outcomes. Results from this study also point to a need for better measures of emotions that are more closely directed at agents of organizational experiences.</p>

Full textAbstract:
A link between poor sleep and abnormal health outcomes has been established.The majority of this research is conducted in Western, high-income country (HIC) settings which warrants the question of how relevant the findings and the derived consensus statements are to low-middle income countries (LMICs). Sleep duration and quality are known to be affected by cultural, social, environmental and geographical influences which vary significantly between LMIC and their HIC counterparts. This thesis provides a thorough examination of objective and subjective measurements of sleep in a LMIC setting. Objective and subjective measures of sleep were obtained as part of an actigraphic sub-study nested within the Colombo twin and singleton study, a cohort study of twins and singletons randomly selected from Colombo, Sri Lanka. Results comparing actigraphic and self-reported sleep duration indicated that Sri Lankans have short sleep duration; averaging 6.4h (SD 1.5) self-reported and 6.0h (SD 0.9) actigraphically. Poor sleep quality was prevalent with an average WASO of 49 min, and sleep efficiency <85%. Bias was observed, with self-report consistently over-reporting sleep on average by 27.6 min (95% CI: -0.68, -0.24) compared to objective measures, but wide individual variation in disagreement, ranging from overreporting by 3.34h to under-reporting by 2.42h. Agreement between subjective and objective measurements of sleep quality was also assessed. Objective indices of sleep efficiency, sleep onset latency and wake after sleep onset did not agree with each other and were unable to be combined into more useful composite indices as a ‘global’ measure of an individual’s satisfaction with their sleep. Given the high cardiometabolic morbidity in Sri Lanka and poor measurement agreement observed, this warrants further investigation and supports the need for culturally appropriate, reliable, and valid assessment for analytic epidemiology in non-Western settings.

Full textAbstract:
The purpose of this quantitative cross-sectional study was to examine the association between African Americans' (AA) self-reported sleep quality and health problems in a community sample of adult AAs. This study was grounded in McEwen's theory that brief and long-term sleep deprivation triggers a stress response that increases allostatic load, which leads to ill health and poor sleep quality. The sample of volunteer participants for this study (N =121) was drawn from a community base of AA adults, aged 20 -70, who resided in the suburbs of Atlanta, Georgia and attended 1 of 3 local churches. Participants completed a self-administered survey consisting of structured standardized scales that covered the perception of stress, racism, sleep quality, social support, and perceived burden from physical and psychological symptoms. Multiple regression and correlation analyses were used to test hypothesized relationships among study variables and poor sleep quality. The results of this study found that health problems were positively correlated with poor sleep quality. The mediating and moderating role of social support, psychological stress, and racism on health and sleep quality were assessed. Psychological stress and perceived racism were found to mediate the relationship between poor sleep quality and health problems; however, social support did not. Psychological stress, perceived racism, and social support were not found to moderate the relationship between health problems and sleep quality. The results of this study contribute to knowledge and can inform health practice about the relationship of health problems and sleep quality among African Americans, as well as the role of stress and racism in exacerbating both health problems and sleep quality in this population.

Full textAbstract:
Rest-activity circadian rhythm (RAR) analysis is a valuable tool to evaluate daily physical activity levels and sleep quality in breast cancer (BC) women, including BC survivors, a population less considered in the scientific literature. Indeed, the role of physical activity is recognised even in tertiary cancer prevention due to its action either on physical or psychological human spheres. In managing the quality of life in BC women, sleep assessment and its relationship with physical activity also raise attention. Several studies reported that an increase in physical activity practice might lead to better sleep quality. All these aspects have been less investigated in BRCA1/2 carrier women. BRCA1/2 are deleterious and high-invasive gene mutations, predisposing to a very aggressive breast and/or ovarian cancer also at a young age.
The present PhD thesis evaluates RAR, sleep, and their relationship in two populations: a cohort of 5-year BC survivors and a sample of BRCA1/2 women.
For the first study, 28 women (15 5-year BC survivors and 13 healthy controls) were 7-day long actigraph monitored and RAR analysis was performed with both parametric and non-parametric approaches. BC survivors showed a statistically lower MESOR (Midline Estimating Statistic of Rhythm), amplitude, L5 (nocturnal activity), and M10 (daily activity), while IV (Intradaily Variability) was higher than the control group. These results are the first experimental evidence that RAR alterations persist after 5 years since the primary diagnosis. Furthermore, BC survivors are less active than healthy controls and need practical intervention to increase their activity levels.
For the second study, 27 women with BRCA1/2 mutations were 7-day long actigraph monitored, while 63 filled in the PSQI (Pittsburgh Sleep Quality Index) and the GSL-TPAQ (Godin Shepard Leisure-Time Physical Activity Questionnaire) questionnaires to assess sleep and physical activity, respectively. The 27 actigraph-monitored women were stratified, based on the development of cancer diagnosis, in affected and unaffected. RAR and actigraphic sleep analysis showed no statistically significant differences between the two groups, even though the affected women seemed to sleep worse than the unaffected. Based on the PSQI score, the women were stratified into good and bad sleepers: good sleepers were significantly more active than bad sleepers. Based on the GSL-TPAQ score, women were stratified into active and inactive: active women showed a better body composition and significantly lower insulin level and better sleep than inactive women. Finally, the regression analyses disclosed the positive effect of physical activity on sleep. More specifically, the prevalence ratio of being a good sleeper significantly increased with the increase in amount, intensity, and frequency of physical activity. This cross-sectional analysis of 63 women sheds light on a possible association between physical activity and sleep in BRCA1/2 mutation carriers. Considering the large attention that the BRCA1/2 carriers’ quality of life is receiving, a physical activity intervention could potentially improve the sleep quality in these women, also reflecting in an enhanced quality of life.

Full textAbstract:
Sleep is not a solitary activity for the majority of adults, this impacts sleep quality, health, and well-being. Couples experience sleep concordance, or a synchronization of sleep-wake times, which can improve and diminish sleep quality (Gunn et al., 2015). This study explores the association between sleep concordance and sleep quality by examining attachment style as a moderator. Daily sleep diaries were completed by 179 heterosexual couples. Sleep concordance was calculated by dividing total time partners were in bed together by total time at least one partner was in bed each day. Data were analyzed using a multilevel model described by Bolger and Laurenceau (2013). There was a positive association between daily sleep concordance and sleep quality for men. Women with higher secure attachment style scores reported greater sleep quality, and women with higher insecure attachment style scores reported lower sleep quality. Among women with higher secure attachment style scores and lower avoidant attachment style scores there was a negative association between mean sleep concordance and sleep quality. There was no association between sleep concordance and sleep quality for higher anxious attachment scores. Future research is needed to address causal relationships. Findings indicate men and women may experience sleep concordance differently.

Sleep is an essential behavior for life and obeys to a complex biological, psychological, social and cultural process with multiple implications in the quality of life of individuals. Sleep quality has been investigated dramatically in the past 20 years because of its role in the physical and mental health of clinical populations, as well as, in the search of more normative values in non-clinical populations. Still, although there has been an increasing interest on the implications of sleep on health, the empirical evidences with non-clinical populations are almost nonexistent.
These investigation´s main objectives were to analyze the impact of sleep quality on the depression, anxiety and stress (mental health indicators) of a non-clinical population, and to evaluate if the relationship between these variables is moderated by gender, age and country of origin. A total of 1552 participants from three different countries (Portugal, Spain and Brazil) answered to a questionnaire with two different validated instruments which measure sleep quality and mental health indicators.
The obtained results confirmed the initially proposed hypothesis. We attested that sleep quality has a significant impact on the mental health indicators. As well, we verified that the relationship between sleep quality and the mental health indicators in study (depression, anxiety and stress) is only moderated by the country of origin. In accordance with our main results and conclusions we outlined some strategies to promote awareness and early interventions on quality of sleep, targeting the specificity of each population/individual.<br>O sono é um comportamento essencial à vida e obedece a um complexo processo biológico, psicológico, social e cultural com múltiplas implicações na qualidade de vida dos indivíduos. A qualidade do sono tem vindo a ser investigada de forma exponencial nos últimos 20 anos, quer pela sua importância na saúde física e mental de populações clínicas, quer pela procura de valores normativos em populações não-clínicas. Contudo, apesar do interesse crescente pelas implicações do sono na saúde, as evidências empíricas com populações não-clínicas são quase inexistentes.
A presente investigação teve como objetivos principais analisar o impacto da qualidade do sono na depressão, na ansiedade e no stresse (indicadores de saúde mental) numa amostra não-clínica e, averiguar se a relação entre estas variáveis é moderada pelo género, pela idade e pelo país de origem. Participaram neste estudo um total de 1552 indivíduos de três países distintos (Portugal, Espanha e Brasil). Os participantes responderam a um protocolo de medidas de autorrelato constituído por instrumentos validados que avaliam a qualidade do sono e os indicadores de saúde mental.
Os resultados alcançados confirmaram maioritariamente as hipóteses inicialmente propostas. Constatou-se que a qualidade do sono tem um impacto significativo nos indicadores de saúde mental. Verificou-se ainda que a relação entre a qualidade do sono e os indicadores de saúde mental em estudo (depressão, ansiedade e stresse) é apenas moderada pelo país de origem. De acordo com os principais resultados e conclusões, foram apontadas algumas estratégias de promoção de sensibilização e intervenção precoces na qualidade do sono, desenvolvidas segundo as especificidades da população e/ou indivíduo.

The main purpose of this study was to investigate whether drink (58% Kinmen Kaoliang) before sleep will improve sleep quality or not.
20 healthy subjects, including 5 normal sleep men and women, 5 disorder men and disorder women were enrolled in this study. There are three steps in this measure, no drinking before sleep for 5 days, drinking before sleep for 5 days, and stop drinking for 5 days. Subjects consumed 0.3g per kilogram of body weight (g/kg) (58 percent alcohol), respectively, before 1 hour going to bed. Based on measurement methods-Cardiopulmonary coupling (CPC) was recorded sleep quality everyday. And the Pittsburgh Sleep Quality Index (PSQI) was recorded after no drinking, drinking, and stop drinking. Every stage was done for five days.
The results of this study are as follows: (1)The scores of sleep quality, drinking before sleep are better than no drinking, stop drinking are better than no drinking. (2)The improvement of sleep quality scores, men are better than women, disorder subjects are better than normal subjects. (3)All subjects had shortest sleep latency when they drank before sleep, stop drinking was the second, no drinking was the longest. (4)Compared with no drinking, all subjects had longer total sleep time when they drank before sleep. The effect persisted 5 days for normal sleep subjects, but no effect on disorders. (5) Compared with no drinking, all subjects had longer deep sleep time when they drank before sleep. The effect persisted 5 days for normal and disorder sleep subjects. (6)Compared with no drinking, all subjects had less sleep apnea times when they drank before sleep. The effect persisted 5 days for normal and disorder sleep subjects. (7)Compared with no drinking, all subjects had higher sleep quality when they drank before sleep on PSQI questionnaire. The effect persisted 5 days for normal and disorder sleep subjects. (8)Compared with no drinking, all subjects had lower sleep intency when they drank before sleep on PSQI questionnaire. The effect persisted 5 days for normal sleep subjects, but no effect on disorders.

Full textAbstract:
碩士<br>輔仁大學<br>臨床心理學系碩士班<br>100<br>Introduction: Research about repetitive thought and mental disorders has been extended form depressive and anxiety disorders to insomnia, and many studies focus on the relationship between rumination, worry and sleep quality. According to the neurocognitive model of insomnia proposed by Perlis et al.(1997), the effect of repetitive thought on sleep may be mediated by increased pre-sleep arousal. The participants of this study are young adults. The purpose of this study is to investigate the relationships between rumination, worry, pre-sleep arousal and sleep quality. The measurements of subjective pre-sleep arousal and subjective sleep quality in study 1 are self-report questionnaires. The measurements of objective pre-sleep arousal are polysomnography in study 2, and measurements of objective sleep quality are actiwatch and polysomnography. This study explored both subjective and objective measurements to examine: 1)the relationships between rumination, worry and sleep quality, 2) the relationships between rumination, worry and pre-sleep arousal, and 3) the relationships between pre-sleep arousal and sleep quality, then we examined the mediator effect of pre-sleep arousal between the prediction from rumination and worry to sleep quality.
Method Study 1:The participants were 202 college students (130 women, age between 18-30). They finished the following self-report questionnaires: Ruminative response style questionnaire (RRS), Penn state worry questionnaire (PSWQ), Pre-sleep arousal scale (PSAS) and Pittsburgh sleep quality index (PSQI).
Study 2: The participants were 30 college students (21 women, age between 18-22) randomly selected form study 1 after ruling out moderate to severe depression or anxiety by Beck depression inventory-second edition (BDI-II) and Beck anxiety inventory (BAI). And they finished consecutive 7 days of actiwatch record and one night polysomnography record.
Results Study 1: After factor analysis of RRS and PSWQ, three factors retained: dwelling on the negative, worry engagement and active cognitive appraisal. The following correlations with pre-sleep cognitive arousal were significant: dwelling on the negative, worry engagement and active cognitive appraisal. The following correlations with pre-sleep somatic arousal were significant: dwelling on the negative and worry engagement. The following correlations with PSQI global score were significant: dwelling on the negative, worry engagement and active cognitive appraisal. The following correlations with PSQI global remained significant after ruling out moderate to severe depression and anxiety: dwelling on the negative and worry engagement. The results suggest that people with higher score of dwelling on the negative or worry engagement would experience higher level of pre-sleep arousal and poorer subjective sleep quality. The results of regression analysis and structure equation model (SEM) analysis support pre-sleep arousal is a mediator between the prediction from repetitive thought to sleep quality.
Study 2: For actiwatch, dwelling on the negative was marginally correlated with increased wake after sleep onset and with decreased sleep efficiency. Worry engagement was correlated with increased sleep latency measured. Pre-sleep cognitive arousal was correlated with increased sleep latency. Pre-sleep somatic arousal was correlated with increased sleep latency and decreased sleep efficiency. For polysomnography, worry engagement was correlated with increased sleep latency. In sleep onset period, pre-sleep somatic arousal was correlated with increased EEG beta-1 activity.
Conclusion: This study examined the relationships between rumination, worry and sleep quality. The results suggest dwelling on the negative and worry engagement can predict higher pre-sleep arousal, pre-sleep arousal can predict poor subjective quality, and pre-sleep arousal is the mediator between the effect of repetitive thought on sleep quality. The results of actiwatch suggest that dwelling on the negative and worry engagement are correlated more severe sleep initiate or maintenance difficulity. We can postulate that the psychophysiological effect of rumination and worry would be extended by increased pre-sleep arousal, and further impact on sleep quality.

碩士<br>國防醫學院<br>護理研究所<br>97<br>Aim: The study’s aims were to understand the current condition of sleep quality、severity of depression and quality of life of nursing staff to investigate the relationship among sleep quality severity of depression and quality of life, and the predictability of sleep quality and severity of depression with respect to quality of life.
Methods: A cross-sectional design study was conducted with a convenient sample of 652 female nurses from five regional hospitals in Taiwan during April 2008. The Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI-Ⅱ version) and the World Health
Organization Quality of Life Instrument-BREF(WHOQoL-BREF)
were used to collect data. Data analysis included descriptive statistics, independent t tests, analysis of variance (ANOVA), Pearson correlations and multiple regressions.
Findings: The mean PSQI scale was 3.94, indicating good sleep quality, while the mean BDI score was 9.79, indicating most nurses had no depressive symptoms, Regarding WHOQol four domains. The
mean general quality of life scale was 2.82, The mean physical domain scale was 13.49, the psychological domain scale was 12.15, the social relationship domain scale was 13.01 and the environmental domain scale was 12.16. All scores are lower than scores of normal females in Taiwan. Moderate or more significant negative correlations are noted among sleep quality, severity of depression and four domains of quality of life. The self-evaluation of health condition can predict the physiological domain up to 27.8%. Severity of depression can predict the psychological domain and social domain up to 43.1% and 20.9% respectively. Compared to cases of the same ages, level of happiness can predict the environmental domain up to 24.5%. Self-evaluation of health condition and severity of depression can predict the all four domains of quality of life.
Conclusions: Most nursing staff had good sleep quality, severity of depression within normal range but inadequate quality of life. Hence, to improve the general quality of life, monitoring the severity of depression and promotion of health behaviors should be prioritized.

A qualidade do sono foi determinada, subjetivamente, através do índice de qualidade do sono de Pittsburgh, questionário de sonolência em adolescentes de Cleveland e do questionário sobre sono para adolescente. O questionário PedMidas (“Paediatric Migraine Disability Assessment”) foi aplicado, nos adolescentes com enxaqueca, no sentido de determinar a incapacidade provocada pela mesma.Resultados: foram incluídos, neste estudo, 52 controlos (idade média 15,67 anos; 51,9% do sexo feminino) e 30 doentes (idade média 15,23 anos; 56,7% do sexo feminino). Os adolescentes com enxaqueca reportaram mais dificuldades no sono, com pior eficiência (p=0.007) e mais distúrbios do sono (p=0,045). A incapacidade provocada pela cefaleia não se correlacionou com as dificuldades do sono ou com a sonolência diurna. A amostra de doentes também apresentou maior rácio de privação do sono (24,0% vs 11,6%, OR=2,40) e maior prevalência de hábitos de sesta (16,67% vs 3,85% em dias de escola, OR=5,00 e 23,33% vs 13,46% nos outros dias, OR=1,96). Quarenta porcento dos doentes vs 44,2% dos controlos sentiram que não estavam a ter horas de sono suficientes e, 18,5% vs 25,0% queixaram-se de sonolência diurna durante muitos ou todos os dias da semana.Conclusão: os adolescentes com enxaqueca reportaram pior qualidade de sono que os controlos saudáveis, no entanto, a generalidade dos adolescentes parece ter uma fraca qualidade de sono. Medidas de higiene do sono devem ser promovidas nesta faixa etária no sentido de, prevenir os efeitos prejudiciais de uma fraca qualidade de sono nesta fase do desenvolvimento.<br>Objective: to assess sleep quality in adolescents diagnosed with migraine headache.Methods: a prospective, cross-sectional study was conducted in patients with migraine headache and healthy controls ranging in age from 13 to 18 years old. Sleep quality was determined, subjectively, using Pittsburgh sleep quality index, Cleveland scale and sleep questionnaire for adolescents. The Paediatric Migraine Disability Assessment was used to determine headache-related disability in adolescents with headache.Results: 52 healthy controls (mean age 15.67 years; 51.9% females) and 30 patients (mean age 15.23 years; 56.7% females) were included in this study. Migraineurs reported more sleep difficulties with worse habitual sleep-efficiency (p=0.007) and more sleep disturbances (p=0.045). No correlation was found between headache-related disability and sleep difficulties or daytime sleepiness. Migraine sufferers also had a higher ratio of sleep deprivation (24.0% vs 11.6%, OR=2.40) and a higher prevalence of napping habits (16.67% vs 3.85% on school days, OR=5.00 and 23.33% vs 13.46% on other days, OR=1.96). Forty percent of patients vs 44.2% of controls felt that they were not getting enough sleep and 18.5% vs 25.0% felt sleepy during the day from a lot of times to everyday.Conclusion: Migraineurs reported worse sleep quality than healthy controls, however, adolescents in general appear to have poor sleep quality. Sleep-hygiene measures should be promoted in this age group, in order to prevent the detrimental effects of a poor sleep quality at this phase of development.

碩士<br>輔仁大學<br>資訊工程學系<br>100<br>With the vigorous development of personal health records and the rising of Sleep Medicine, the demand for sleep management services has grown significantly. These services proposed sleep quality assessments to help users better understand their sleep, and attract users to establish complete personal sleep record. However, most sleep-related services use only total sleep time to assess the quality of sleep. These services ignore the impact of sleep physiology, and the credibility of assessment result is low. In this thesis, we propose an assessment mechanism based on the analysis of sleep pattern to enhance the credibility of evaluation result.
Our personalized assessment mechanism considered evaluation sleep data sources on the physiological impact of each sleep stage. Besides integrating multiple data sources of sleep monitoring, our research defined the sleep data storage formats and exchange formats. Based on the sleep experiment from four subjects for total five weeks, our mechanism is capable to provide a more intuitive and credible sleep quality assessment.

Inadequate time for sleeping or bad sleep quality can cause lethargy during daily routines, and even may result in diabetes, cardiovascular, hypertension and higher cholesterin. Listening to music is a way to help people falling asleep, further the system can be used to evaluate what specific music type can help in sleep quality implement. The main objective of the study is to develop a system that can assess the sleep quality based on total sleep time, sleep efficiency and sleep latency.
This study implemented a portable sleep quality assessment system, and which is consisting of a wearable physiological signal collection device, a data analysis software, and data storage subsystem. During sleep, user can use the wearable device to collect EEG, PPG and body movement status. For the sleep quality improvement by music research, the system generates music, and calculate the sleep assessment features. Also all the data will be stored in a database for later play back and checking.
Performance on the system shows it can wireless, and losslessly transmit all the data to remote pc. These data can be real time processed for delta wave detection, and head movement sensing. With these information, the total sleep time, sleep efficiency and sleep latency can be derived. Also the sleep depth can be measured. When the sleep depth to a certain degree, the music generated by the system will be ceased. The results valid the system in sleep quality assessment and its application for evaluating sleep improvement by music.

The purposes of that study were to (1) examine the consistency of sleep parameters measured by wrist actigraphy, sleep diary, and Pittsburgh Sleep Quality Index (PSQI); and (2) evaluate the related factors. Based on 7 day’s data from 24 patients with lung cancer under chemotherapy, this study found that there was a good agreement between actigraphy and sleep diary in determining sleep latency and total sleep time (ICC = .478 - .605). However, poor agreement were found in sleep efficiency, wake after sleep onset (WASO) time, WASO bouts, nap time and nap bouts (ICC = .003 - .274). For consistency between actigraphy and PSQI, good agreement was found in bed time, total sleep time and sleep latency (ICC = .492 - .724), but poor agreement in sleep latency (ICC = .064). The Bland & Altman plot showed worse agreement between different assessment methods was associated with the longer of sleep latency, WASO time, WASO bouts, nap time and nap bouts. Actigraphy type, sleeping location, sleeping alone, sleep disturbances, anxiety or depression were factors that influenced the agreement between the methods. The findings of this study suggest that using actigraphy to assess the sleep parameters may need to control for the related factors, and use of build-in event marker of actigraphy may help reducing inconsistency.

Full textAbstract:
碩士<br>中國醫藥大學<br>臨床醫學研究所<br>96<br>Background: According to the International Study of Asthma and Allergies in Childhood study phase Ⅲ, there has been an increasing trend of asthma prevalence in Taiwan during the last 30 years. Recently, a national survey in Taiwan demonstrated the general hospitalization rate of asthma in the children group (<18 yr old) increased significantly from 1996 to 2002.Asthmatic children have been reported to complain about poor sleep quality. Recent research has demonstrated the relationship between sleep and circulating cytokines. There are few studies delineating the relationship between immune mediators and sleep quality in asthmatic children. This cross-sectional study aims to assess the relationship of serum cytokine level and sleep quality in asthmatic children.
Methods and materials: After an initial screening phase at allergic clinic visits, 90 asthmatic children aged 6 through 12 years were enrolled to complete one Chinese version of the (Childhood) Asthma Control Test. A specially-design questionnaire concerning sleep quality of asthmatic children was administered to all subjects and parents. We assessed the serum level of certain immunological parameters, including interleukin (IL)-4, IL-6, IL-10, IL-12, total immunoglobulin (Ig) E, and prolactin at enrollment.
Results: Subjects with an ACT score of 20 or more were assigned as the well-controlled group (N = 68) and those with a score of 19 or less were assigned as the inadequately-controlled group (N = 22). Mean scores for level of sleep disturbance did not have a significant difference between the well-controlled group and inadequately-controlled group (8.14 ± 7.193 vs. 4.91 ± 4.203, respectively; p = 0.063). Mean scores for the subjective sleep perception showed a significant difference between the well-controlled group and inadequately-controlled group (4.59 ± 1.149 vs. 3.95 ± 1.090, respectively; p = 0.028). Mean levels of assessed cytokines IL-6, IL-10, IL-12 and total IgE did not show a significant difference in relation to the level of asthma control. In the well-controlled group, the good sleepers had a significantly lower mean level of IL-10 (1.78 ± 1.05 pg/mL vs. 3.92 ± 3.81 pg/mL, respectively, p = 0.026) and higher mean ratio of IL-12/IL-10 (0.93 ± 1.17 vs. 0.41 ± 0.26, respectively, p = 0.03) compared to the poor sleepers. Additionally, there was a significantly enhanced serum prolactin level in the good sleeper subgroup, in comparison with the poor sleeper subgroup (10.03 ± 7.15 ng/mL vs. 7.73 ± 4.63 ng/mL, respectively, p = 0.037). Of both subgroups, the concentrations of IL-6, IL-12 and total IgE did not reach a significant difference.
Conclusion: These results suggested an improvement in asthma control would promote better sleep quality. Good sleep is associated with a lower IL-10 level, a higher prolactin concentration, and a higher TH1/TH2 ratio. Prolactin may have a potential role in this immunity shift. Furthermore, this pattern of immune profile may have therapeutic benefits on asthma management. Thus, it can be anticipated that further insight into the functional role of cytokines on sleep quality of asthmatic sufferers will result in novel therapeutic perspectives. Nonetheless, more research is warranted to see whether the reduced IL-10 level and elevated IL-12/IL-10 ratio in the good sleepers is of therapeutic benefit. Clinicians should make an effort and do more to shift the spiral to a positive direction by helping asthmatic children to gain well-control of their asthma and get the sleep they need.

Full textAbstract:
碩士<br>長庚大學<br>資訊工程研究所<br>96<br>The sleeping status has major relationship with physiological and psychological health. When the sleep is disturbed, not only the sleepiness, depression and anxiety will be occurred, but also the attention and working efficiency will be reduced at daytime. In addition, the person with sleep disorder is apt to suffer from various chronic diseases, such as cardiovascular disease, diabetes etc. It will greatly influence personal health physically and mentally.
This research attempts to establish a set of self evaluation system for sleep quality with service orientation architecture. The personal sleep problem will be found through complete sleep evaluation, efficient management, visual reporting form and group database. The system is consisted of five service modules: (1) Account service: It is used for the management of User account data and authorization. (2) Questionnaires service: It is used for editing various questionnaires and generating platform programs. (3) Record service: It is used for establishing personal health for inspecting the long-term variation tendency. (4) Report service: It is used for the feedback of assessment result. (5) Reminding service: It can provide personalized setting to remind the important affairs..
In order to verify the correlation between the subjective scale (Pittsburg) and the objective scale (Polysomnography), 8 students are used to carry on PSG experiment and the questionnaire is filled. The correlation analysis is conducted for deep sleep percentage and questionnaire score in PSG report, and the negative correlation is revealed (r=-0.514, p=0.01; Pearson). It shows when the subjective sleep quality is better, the deep sleep time will be relatively longer. And when the correlation analysis is conducted for sleep latency and questionnaires score, and the positive correlation is revealed (r=0.54, p =0.006). It shows when the subjective sleep quality is worse, the sleep latency will be longer.
If e-questionnaires is used simply, 36% of subjects consider the filling willingness can be increased. But if the system can provide immediate feedback of result, 66% of subjects consider the filling willingness can be increased. So, the offer of feedback will be the key factor which influences the filling willingness of user. As for the reminding mechanism of user, it is unable to receive the reminding effect after notifying four times averagely. The excessive push will cause user to be repugnant. The experimental data show that the suitable reminding frequency is once per seven days.
The assessment result is slightly different among groups. As for the teachers and staff (n=11), the 63% of faculties's sleep quality are bad, the major cause is stress factor (54%), and the influence caused is fatigue (45%). As for the graduate students (n=40), 42% students's sleep quality are bad, the major cause is stress factor (52%) too, but the abnormal ratio of anxiety (15%) and depression (10%) is the highest in three groups, and the influence caused is fatigue (71%), which is also the highest in three groups. As for the undergraduate students (n=160), the subjective feeling of insomnia is 51%, but the stress ratio is 36%, which is lower than other two groups, and the influence caused is fatigue (59%).

碩士<br>國立雲林科技大學<br>工業設計系<br>103<br>Sleep is one of the most essential factors for human healthy. Lacking of good sleep quality may be a burden to healthy. Exercise can enhance sleep quality. This study aims to explore whether exercise can enhance sleep quality, and to investigate the trend of sleep quality.
Twenty voluntary subjects (10 male and 10 female) aged 20-30 which including 9 students and 11 non-student were recruited in this study. Experiment lasts 15 days, 5 days for a stage. A TXEK3 in-house Sleep Quality Examiner and the Sleep Quality Index were used to measure the sleep quality of the subjects. The dependent variable contains a total of 12 indicators of subjective and objective sleep quality and sleep and other situations. Independent variable contains: sex (male and female), job (student and non-student), situation (non-exercise, ergometer exercise, stop exercising).
The results demonstrated that doing ergometer exercise can improve the sleep quality effectively. Doing ergometer exercise early 4-5 hours of bedtime can improve 20.9% of Sleep quality, shortened 6.2 minutes of Sleep latency, increase 15.8% of Stable sleep time and release the situation of Sleep apnea up to 64.4%.Furthermore, it affects males and females the same, but it affect students more effectively than non-students in Sleep quality, Sleep latency and Stable sleep time, its percentage of difference is 7.9%, 17%, 5.5% respectively. Result supports that doing ergometer exercise can improve the Sleep quality of students more effectively than non-student.

碩士<br>美和科技大學<br>健康照護研究所<br>99<br>Depression, as a disability, not only harms the individuals, but also causes negative impact on the family and the society. While a high proportion of depression haunts the homeless, little has been discussed about the health of the vagrants. This paper aims to explore the sleep quality and depression of the homeless. As a cross-sectional study with purposive sampling, this paper collects data such as demography of homelessness, health status, living conditions, sleep quality, and depression symptoms, etc, by the structured questionnaires. 358 participants are engaged in 13 spots of Zenan Homeless Social Welfare Foundation in Taiwan.
The study results showed that 21.51% prevalence of depression in the homeless than the general population had a higher depression symptoms; age of risk of each additional year-old 0.96(times) increased risk of depression, 1.432 as they suffer from one more disease, sleep Quality score for each point increase in the probability of suffering depression increases 1.385, more than three years of the homeless suffer from depression, increased risk of 3.110 , 4.678 more for those who become homeless involuntarily than voluntarily.
The sleep quality of the homeless is poor. The probability of poor sleep quality increases by 1.128 (times) on every rising 1 point of TDQ, 1.516 as they suffer from one more disease, 1.454 as they become ensnared in their ever-increasing worry about starving, 0.37 more for those who become homeless involuntarily than voluntarily.
Sleep quality (PQSI), as the most important predictor of depression, accounts for 36.8% in depression.
This paper shows that the health of the homeless, sleep quality, and depression are closely related. Due to the fact that poor living environment of the homeless affect their mental and physical health, it is important to offer them living essentials and safe shelter in order to reduce depression among the homeless.

碩士<br>高雄醫學院<br>護理學研究所<br>82<br>This is a study of survey. The main purpose is to explore the elderly women's sleep pattern and the related factors. The subjects are two hundred elderly women over 65 years of age. The mean of their age is 74.44 ± 6.11. On completion of questionnairs face-to-face interviews were conducted in the subjects' home. The research instruments inculding the Demographic Inventory, Quality of Sleep, Sleep Condition, Sleep and Bedtime Routine, The Environment of Sleep, Life Event and Common Beliefs about Sleep. The instruments were evaluated by experts to measure the content validity. Test-retest reliability and inter-rater reliability were used. The inter-rater relibility was 98%. Data was collected by one trained senior nursing student and one graduate student. The collected data was analyzed by Statistical Analysis System (SAS).
The results were found that the majority of self- preceived diseases among the elderly women were muscle disease, eyes disorder and bone disease. The most using drugs were eye drops. The most of leisure activities and exercises were chat, walk and moveing their limbs. The most of time to go to bed was 8:30 PM, the most of morning awakening time was 5:30 AM, the mean of totol sleep time was 5.65 hours. The most for number of nocturnal awakening were 1 ～ 2 times for the elderly women. The most causes of nocturnal awakening were toilet and natural awakening. Over 65% of the elderly women have a bedtime routine, 85.5% of the elderly women went to toilet, brushed their teeth, watched TV and listened to radio and taked snack before going to bed. They think the execution of bedtime routines would help them have a good night sleep. The elderly women's sleep quality in the investigating week, including bedtime, time of awake, were the same as last week.
Majority of ours subjects were awakened in the midnight, but nobody were slept at once. 74.5% of the elderly women felt rested when they awakened in the morning and 76% of the women felt good all day. 38.5% of the subjects think their soundness of sleep was light sleep, 13% women wasn't received total sleep hours enough , 12.5% women felt unsatisfactory sleep. The resluts was found that the age, education, self-preceived disease (demographic variables), medication taking , leisure activities, exercise (personal habit), total sleep time, the number of nocturnal awakings (sleep condition), the environment of sleep, life event influenced the quality of sleep in the conceptual framework of this study. Stepwise multiple regressions were computed. The age, self-preceived disease, exercise, the environment of sleep, life event, the number of nocturnal awakings and total sleep time were the most powerful predictors. Together they explained 50.8% of the variance for the quality of sleep. However,the results suggest would be useful to nurse in practice, education and research as they find the causes of sleep problems and paln the nursing interventions and promote the quality of sleep in the elderly women.

碩士<br>國立雲林科技大學<br>設計學研究所<br>107<br>Sleep is a basic requirement of human beings and a necessary condition for promoting physical and mental health.Exercise is a way to improve the quality of sleep.The parasympathetic nerve is one of the factors that affect sleep.Exercise can improve the regulation of cardiac arrhythmia and enhance the parasympathetic nerve.The single action of squat can enhance the muscles and bones of the lower extremities while enhancing the parasympathetic activity.The effect of squat on sleep quality was investigated in this study.
This study collected 32 volunteers and divided them into two groups: youth group and elderly group.The youth group consisted of 16 people (8 men and women) with average age of 24 years (SD= + 4.2 years). The elderly group consisted of 16 people (8 men and 8 women), with an average age of 63 years (SD= + 4.2 years).The subjects performed the three phase of the experiment for 13 days.The first stage was no squat movement (three days).In the second stage, squat exercise 3-4 hours before bed (5 days), 150 times a day.In the third stage, the squat movement was stopped (5 days).Squat squatting to the thigh and parallel to the ground.The squat standard action is performed at the frequency of metronome 1/10 HZ.According to the variable items, the sleep quality of the subjects in the absence of exercise, training and after stopping exercise were measured by Fitbit charge 2, and 11 indicators of sleep quality were measured.Including: actual sleep time, REM time / proportion, shallow sleep time / proportion, sleeping time / proportion, NREM time / proportion, total sleep time and sleep efficiency. The self variation term was 2 levels of sex: male and female; 2 levels of the group: young people and old people; exercise status 3 levels: no exercise, squat exercise, and stop squatting.
The study results showed that:(1) Squatting exercise before bedtime can increase sleep efficiency, increase REM time, increase deep sleep time / proportion, reduce light sleep ratio, and stop the movement after 5 days.(2) REM sleep time / ratio, sleeping time / ratio and total sleep time were higher in young people than in elderly people.(3)The actual sleeping time of young women is higher than that of older women.There is no difference in the actual sleeping time between men and young men.(4)Young women at NREM time were older than older women, and men at NREM time were younger than men aged

Full textAbstract:
The complaint of insomnia in older adults is associated with the use of hypnotics. This study was aimed at exploring possible differences between self-categorised good sleepers and poor sleepers on a range of variables, and the factors associated with the use of hypnotic medication amongst the elderly. Participants in the current study were aged 60 to 98 years old. A total of 74 (28 males, 46 females) older adult hostel residents participated in the current study. Twenty-two participants were self-reported good sleepers, and 52 participants were self reported poor sleepers, with 21 using benzodiazepine hypnotic medication regularly and 31 not using hypnotics. The measures used included the Pittsburgh Sleep Quality Index (PSQI), Geriatric Depression Scale (GDS), The Beck Anxiety Inventory (BAI), Sleep Beliefs Questionnaire (SBQ), and World Health Organisation Quality of Life-Brief (WHOQoL). The findings demonstrated that self-categorised good sleepers had significantly better sleep quality and habitual sleep efficiency, and significantly shorter sleep latency, regardless of hypnotic use. It was also found that good sleepers and poor sleepers taking benzodiazepines had significantly longer sleep duration than poor sleepers not taking benzodiazepine hypnotics. The prediction that self-classified good sleepers would have lower depressed mood than their self-classified poor sleeping counterparts, whether they were taking benzodiazepine hypnotics or not, was supported. The findings suggested that while self-classified good sleepers had lower anxiety levels than poor sleepers using hypnotic agents, these poor sleepers had significantly lower anxiety levels when compared to their counterparts not using benzodiazepines. Further variables of difference between good and poor sleepers included the psychological and social relationships domains of quality of life. Interestingly, the results indicated that the main role benzodiazepine hypnotic agents have for poor sleepers appears to be longer sleep duration. Benzodiazepine use did not have a significant ameliorative effect on any of the other sleep variables measured in the current sample of hostel dwelling, older adults. The findings indicated that sleep duration and habitual sleep efficiency demonstrated good predictive validity for whether subjective poor sleepers take benzodiazepine hypnotics. It was concluded that an alternative to managing poor sleep needs to be education programs, such as education delivered by nurses or evidence based self-help programs (eg. Morawetz, 2003)

Full textAbstract:
碩士<br>國立交通大學<br>生物資訊及系統生物研究所<br>103<br>Past studies have proven that aromatherapy before sleep can help people relax, and thus effectively improving the sleep quality. However, subjects might claim to have experienced an improved quality of sleep, if they are aware of the aromatherapy taking place. Previous studies revealed that the olfactory system still works during sleep, and is the only human sense that bypasses the thalamus, which controls the function between sleep and wake. Hence, presenting aroma stimulus during sleep is an effective way to eliminate the self-psychological biases, and does not make the sleep arousal. In order to understand and evaluate the benefits of the essential oil with the quality of sleep, this study organizes the experiments, with and without discharging the lavender aroma essential oil during sleep, and several physiological signals are recording simultaneously. The sleep questionnaires are given before and after experimental night to assess the self-reported sleep quality.
The self-reported sleep quality at the experimental night has a significant improvement in the terms of less sleep disturbance and sleep well. The ratio and length of slow wave sleep (SWS) at the experimental night also has the significant increase. The results from the EEG power spectrum activities show the large delta power (0-4 Hz) in non-rapid eye movement stage 3, in contract, the less alpha power (8-13 Hz) and beta power (15-30 Hz) in wake stage at experimental night. In conclusion, this study suggests that exposing the lavender aroma essential oil during sleep not only effectively improve the sleep quality in self-report, but enhance the deep sleep related EEG power activity during sleep, and thus increase both degree and duration of deep sleep and less the length of awake.

Full textAbstract:
碩士<br>國立成功大學<br>工業設計學系<br>103<br>With human development and advance of science and technology, bedding design has been attached much more importance. The thermal discomfort caused by the environmental temperature always disrupts human sleep. Considering the sleep thermal comfort, blanket design has the potential to alter the bedding microclimate to provide a comfortable sleeping environment. Hence, the purpose of this study was to propose an innovative blanket design to improve sleep thermal comfort and sleep quality through understanding the impact of thermoregulation, sleeping postures between humans and blanket and the changes of body temperature in each body segments on sleep.
An innovative blanket has been proposed in this study. To begin with, the design criterion were set up by the discussion of the initial stage focus group. By discussion, the general problems caused sleep thermal discomfort were found and the ways people deal with the problems were discussed. Design principles for the blanket design proposed by this study were: (1) Avoid great differences in skin temperatures between the extremities and the torso; (2) Decrease the blanket movement. Preliminary design concepts were obtained by the second stage focus group and two main features were extracted. Based on the two design features and consideration of the thermal characteristics of different body segments, the final design was developed.
An experimental evaluation was conducted to assess the efficacy of the designed blanket. Result showed that the proposed blanket had more capable of improving sleep thermal comfort and sleep quality. The results of this study clearly support the notion that sleep thermal comfort can be improved by the combination of different materials based on the thermal characteristics of each body segment.
