Total Score Of Sleep Quality Research Articles

Sleep quality and its relationship with quality of life among high-risk pregnant women (gestational diabetes and hypertension)

Background: Sleep is one of the most basic human requirements. This research aims at determining the status of sleep quality and its relationship with quality of life among high-risk pregnant women in Tabriz, Iran, in 2015.Materials and methods: This research was a sectional study done on 364 qualified women in 28–36 weeks of pregnancy suffering from mild preeclampsia and gestational diabetes. The sampling was done as convenience. Personal–social–midwifery questionnaire, Pittsburg sleep quality, and quality of life in pregnancy (QOL-ORAV) were used for gathering data. Multivariate linear regression model was used for determining the relationship between sleep quality and its subsets with quality of life and controlling confounders.Findings: In the current study, the prevalence of sleep disturbance was 96.4%. Mean (SD) of the total score of sleep quality was 10.1 (4.1) and the total score of quality of life was 61.7 (17.3). According to Pearson’s correlation test, there was statistically significant relationship between quality of life and sleep quality and all its subsets except sleep duration and use of sleep medication (p < 0.001). Meanwhile, according to the multivariate linear regression model, sleep latency, day time dysfunction, health status, and home air-conditioning were related with quality of life.Discussion: The findings of current research show that sleep quality is low among high-risk pregnant women and quality of life is medium. So, it is necessary that required training is given by health cares for improving sleep quality and quality of life to mothers.

Sleep quality and related factors among the nurses of the Hospital of Kashan University of Medical Sciences, Iran

Aim: Sleep and rest are the essential physiological needs of human. Nurses are at risk of developing sleep problems than others because of having various shift work. The aim of the present study was to evaluate the sleep quality and related factors in the nurses. Methods: In this cross-sectional study, 200 nurses were selected randomly from Shahid Beheshti Educational Hospital of Kashan University of Medical Sciences, Iran, 2016. Persian version of Pittsburgh Sleep Questionnaire Index and demographic questionnaire were used for the detection of sleep quality. Results: The mean age of cases was 51.31 years, and most of them (73%) were female. The majority of them had rotating shift work and worked over 150 h per month. 95.5% (191 cases) of them had poor sleep quality. The mean total score of sleep quality in females was higher than males (P = 0.04). The nurses with rotating shift work had higher mean total score of sleep quality than nurses with fixed shift work. Nurses with over 150 h per month had more problems in daily function than others (P = 0.04). Conclusion: These results present that the majority of the nurses had poor sleep quality. Poor sleep quality could be affect function, mental and physical health, and secondary effect delivery service to patients. Therefore, attention to this issue and strategies for improved sleep quality is necessary.

The Effect of Relaxation techniques on Quality of Sleep for Patients with End Stage Renal Failure Undergoing Hemodialysis

Many patients on regular hemodialysis have sleep disorders, which not only affect their quality of life but also their immune function. Relaxation techniques are simply designed to teach the patients to relax, and thus improve their ability to sleep. The study aimed to evaluate the effect of relaxation techniques on the quality of sleep of patients with end stage renal failure undergoing hemodialysis. The study was carried out in Hemodialysis Unit at Mubarak Hospital, Tanta University Hospital. A convenient sample of 20 adult patients undergoing hemodialysis was selected, with one group, before and after intervention. Two tools were used for data collection. Tool I includes sciodemographic data assessment. Tool II includes Pittsburgh Sleep Quality Index Scale that measures the sleep quality. The main result showed that the relaxation technique improved the total score of sleep quality and its dimensions in hemodialysis patients. It is recommended that periodic clinical assessment of sleep complaints should become routine for dialysis patients. Also, non-pharmacological methods such as relaxation techniques should be used for the treatment of sleep problems in hemodialysis patients.

Sleep Quality in Medical Students; the Impact of Over-Use of Mobile Cell-Phone and Social Networks.

Poor sleep quality is closely associated with lifestyle habits including use of mobile cell-phones.This study aimed to identify the relationship between sleep quality due to abuse in mobile cell-phones and engagement in social networks. This cross-sectional study was conducted on 380 undergraduate students selected by proportional stratified sampling in Qom, Iran in 2015. Data were collected by two standard questionnaire including Cell-Phone Over-Use Scale (COS) and Pittsburgh sleep quality questionnaire beside the status of usage in cell-phone social networks. T-test, chi-square, Pearson correlation coefficient and multivariate logistic regression were used in data analysis. The mean age of participants was 21.8 ±3.2 yr, 69.1% were female, and 11.7% were married. The mean of COS and sleep quality scores were 48.18 ±17.5 and 5.38 ±2.31, respectively. The prevalence of over-use of cell phone was 10.7% (CI 0.95; 8.8%, 12.6%) and the prevalence of poor sleep quality was 61.7% (CI 0.95; 57.1%, 66.3%). The mean of all aspects and total score of sleep quality showed a direct significant association by cell-phone addiction score except sleep duration score that was inversely. Based on multivariate analysis affected to cell-phone addiction, being male gender and studying in general physician level are the most important predictors of poor sleep quality. Over use of internet and social networks via smart phones is related to poor sleep quality and quantity. Predefined sport programs, educational, cultural, and interesting entertainment are the essential needs for all medical students. These interventions are more important especially for male students who have longer educational.

Impact of pedometer-based walking on menopausal women’s sleep quality: a randomized controlled trial

Objective Sleep disturbances are one of the most common psycho-physiological issues among postmenopausal women. This study was designed to evaluate the impact of walking with a pedometer on the sleep quality of postmenopausal Iranian women.Methods This randomized, controlled trial was conducted on 112 women who were randomly assigned to two groups. The women in the intervention group (n = 56) were asked to walk with a pedometer each day for 12 weeks and to increase their walking distance by 500 steps per week. A sociodemographic instrument and the Pittsburgh Sleep Quality Index were used to collect data. Sleep quality was measured at baseline, 4, 8, and 12 weeks after intervention. The control group (n = 56) did not receive any intervention.Results After 12 weeks, subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction improved to a significantly greater extent in the intervention group than in the control group (p < 0.05). The total sleep quality score was significantly higher in the intervention group than in the control group (0.64 vs. 0.98, p = 0.001).Conclusion This study showed that walking with a pedometer is an easy and cost-effective way to improve the quality of sleep among postmenopausal women. Use of this method in public health centers is recommended.

Cardiac Valve Noise Reduction by Non-Drug Interventions Improves the Sleep Quality of Patients after Mechanical Cardiac Valve Implantation.

To investigate the effects of non-drug interventions on the sleep quality of patients after mechanical cardiac valve implantation. In this prospective, randomized, controlled trial, 64 patients scheduled for mechanical mitral valve replacement were recruited. Patients underwent cognitive behavioral therapy and wore noise cancelling earplugs and eye mask. Sleep quality was evaluated on the 4th after admission and the 5th days after operation. The primary outcome was the total sleep quality score differences between the 4th day after admission and the 5th day after operation. All patients had been suffering from poor sleep quality for a month before admission. There was no difference between both groups on the 4th day after admission. Overall sleep quality in the intervention group was better than in the control group on the 5th day after operation. The subjective sleep quality of the patients in each group was significantly lower on the 5th day after the operation than on the 4th day after admission (P <0.05). Non-drug intervention could improve the sleep quality of patients after mechanical cardiac valve implantation and help the postoperative recovery of the patients.

Assessment of subjective sleep quality in iron deficiency anaemia.

We aimed to assess the effect of anemia on subjective sleep quality in patients with iron deficiency anemia (IDA). One hundred and four patients diagnosed with IDA and 80 healthy individuals, who are gender and age matched, were included in the study. All participants were requested to fill 3 forms: a socio-demographic form (age, gender, marital status, income level and educational status), hospital anxiety and depression (HAD) scale and pittsburgh sleep quality index (PSQI). According to the HAD scale, the average anxiety score was found 9.24±4.37 in patients and 7.58± 4.07 in controls. And, the average depression score was 7.53±4.10 in patients and 6.41±2.74 in controls. The total sleep quality score was 6.71±3.02 in patients and 4.11±1.64 in controls. There was a statistically significant difference in terms of anxiety, depression and sleep quality scores. Linear regression analysis showed no association between anxiety and depression with poor sleeping. IDA affects sleep quality irrespective of psychological symptoms such as depression and anxiety.

Comparing the Effects of Progressive Muscle Relaxation and Guided Imagery on sleep quality in primigravida women referring to Mashhad health care centers-1393

Background & aim: Decreased sleep quality is a common complaint during pregnancy. Relaxation is one of the non-pharmaceutical treatments for sleep disorders. Different techniques could have different impacts on various biological and mental stressors. Therefore, this study aimed to compare the effects of progressive muscle relaxation and guided imagery on the sleep quality of primigravida women. Methods:This three-group clinical trial was conducted on 100 primigravida women, referring to Mashhad health care centers in 2014. All women, who met the inclusion criteria, were randomly assigned to three groups: progressive muscle relaxation, guided imagery, and control groups. The intervention groups performed the exercises twice a day for a period of four weeks at home after two sessions of relaxation training (held during two weeks). Then, the quality of sleep was measured using Pittsburgh Sleep Quality Index. For data analysis, ANOVA, Kruskal-Wallis, paired t-test, and post-hoc test were performed, using SPSS version 11.5. Results: The total score of sleep quality and its components (except use of sleep medication) was significantly lower after the intervention, compared to the pre-intervention period in progressive muscle relaxation and guided imagery groups (P<0.001). Both relaxation techniques were effective in improving sleep quality and its components (P<0.001). However, the effect of guided imagery was more significant than progressive muscle relaxation (P=0.015). Conclusion: Both guided imagery and progressive muscle relaxation positively affected the sleep quality of primigravida women, although the effect of guided imagery was more significant. It is recommended to integrate guided imagery into pregnancy care for primigravida women with sleep disorders.

Effect of extremely low frequency electromagnetic field exposure on sleep quality in high voltage substations

This study aims to investigate the effect of extremely low frequency electromagnetic fields exposure on sleep quality in high voltage substations (132, 230 and 400 KV) in Kerman city and the suburbs. For this purpose, the electric field intensity and magnetic flux density were measured in different parts of substations, and then the occupational exposure was estimated by averaging electric field intensity and magnetic flux density in a shift work. The cases comprised 67 workers who had been exposed to electromagnetic fields in age range of 24–57 and the controls were 110 persons the age ranged 24–50 years. Sleep quality of both groups was evaluated by the Pittsburgh Sleep Quality Index questionnaire (PSQI). Finally, these data were subjected to statistical analysis. The results indicated that 90.5% of cases and 85.3% of controls had the poor quality sleep according to PSQI (P-value=0.615). Total sleep quality score mean for the case and control groups were 10.22 ± 3.4 and 9.74 ± 3.62 (P-value=0.415) ,respectively. Meantime to fall asleep for cases(35.68 ± 26.25 min) was significantly higher than for controls (28.89 ± 20.18 min) (P-value=0.002). Cases had average sleep duration of 5.49 ± 1.31 hours, which was lower ascompared with control subjects (5.90 ± 1.67hours). Although there was a higher percentage for the case group with poor sleep quality than the control group, but no statistically significant difference was observed.

Effect of eye mask on sleep quality in patients with acute coronary syndrome.

Sleep is one of the basic human needs and sleep deprivation causes nu-merous adverse effects on the human body and mind. Due to reduced sleep quality in patients with acute coronary syndrome, this study was carried out to determine the effect of eye mask on sleep quality in patients with acute coronary syndrome. In this two-group controlled clinical trial, sixty patients with acute coronary syndrome in the coronary care units of Baqiyatallah Hospital in Tehran in 2010 were selected by purposeful sampling method and randomly allocated to two groups of case and control. In the case group, in the second night stay, the intervention of eye mask was done per night and by using the Petersburg's sleep quality index; sleep quality was evaluated during and at the end of hospitalization. Then data were analyzed by paired t-test, independent t-test, Spearman and Pearson's correlation coefficient and SPSS software version 19. Total sleep quality score of the case group was significantly decreased after intervention (4.86 ± 1.88) from before intervention (10.46 ± 4.09) (p < 0.000). In addi-tion, total score of sleep quality after intervention in the case group (4.86 ± 1.88) was significant different from the control group (8.43 ± 1.97) (p < 0.005). Using eye mask, as an economical and uncomplicated method, can improve sleep quality in patients with acute coronary syndrome in the coronary care units and can be used as an alternative method of treatment instead of drug therapy.

Sleep Disturbances in Patients With Malignancy and Non-Malignancy

Objective: Aim of the study was to evaluate sleep quality in a small sample of patients with gastro-esophageal reflux disease (GERD) comparing them with the patients under treatment in oncology department. Method: Forty-eight patients were included in the study, 22 of them were recruited from the oncology department (oncology patients: OnPs) and 26 from the gastroenterology department (gastroenterology patients: GEPs) at a university hospital. By senior psychology students, the Hospital Anxiety and Depression Scale and the Pittsburg Sleep Quality Index were administered to the patients. Results: There was no significant difference between the two groups regarding anxiety and depression scores of the patients and their total sleep quality scores. Nevertheless, it has been found that GEPs had higher anxiety scores than OnPs. Conclusion: The regression analysis demonstrated that sleep quality scores are determined only by anxiety scores and that being an oncology or gastroenterology patients, being at a certain age, or gender have no effect on total sleep quality scores.

Health‐related qualıty of lıfe, sleep qualıty, and depressıon in peritoneal dialysis and hemodıalysıs patıents

Health-related quality of life (HRQoL) and sleep quality (SQ) were impaired in patients with end-stage renal disease (ESRD). The impairment of both HRQoL and SQ and being in a depressive mood were found to be associated with increased morbidity and mortality in dialysis patients. We aimed to investigate the association between SQ, HRQoL, and depression, and to define independent predictors of SQ and depression in peritoneal dialysis (PD) and hemodialysis (HD) patients. Ninety HD patients (41 females, 49 males with mean age 50 ± 15.7 years) and 64 PD patients (27 females, 37 males with mean age 52.4 ± 15.3 years) receiving renal replacement therapy for at least 3 months were screened for the assessment of SQ, HRQoL, and depression in this cross-sectional study. A modified postsleep inventory, Short Form of Medical Outcomes Study (SF-36) and Beck depression inventory (BDI) were applied to all patients for evaluating SQ, HRQoL, and depression, respectively. HD and PD patients had similar total SQ scores. Physical and mental component scale of HRQoL were found to be significantly higher in HD patients (p < 0.001). PD patients were found to be much more in depressive mood when compared with HD patients (p < 0.001). Independent predictors of depression in patients were mental component scale of HRQoL, gender (being female), and dialysis modality (being PD patient). Physical component scale was also found to be an independent predictor of SQ. This study showed that despite similar SQ scores between two groups, HD patients had better HRQoL and less depression than PD patients.

Deadlines at work and sleep quality. Cross‐sectional and longitudinal findings among Danish knowledge workers

Exposure to deadlines at work is increasing in several countries and may affect health. We aimed to investigate cross-sectional and longitudinal associations between frequency of difficult deadlines at work and sleep quality. Study participants were knowledge workers, drawn from a representative sample of Danish employees who responded to a baseline questionnaire in 2006 (n = 363) and a follow-up questionnaire in 2007 (n = 302). Frequency of difficult deadlines was measured by self-report and categorized into low, intermediate, and high. Sleep quality was measured with a Total Sleep Quality Score and two indexes (Awakening Index and Disturbed Sleep Index) derived from the Karolinska Sleep Questionnaire. Analyses on the association between frequency of deadlines and sleep quality scores were conducted with multiple linear regression models, adjusted for potential confounders. In addition, we used multiple logistic regression models to analyze whether frequency of deadlines at baseline predicted caseness of sleep problems at follow-up among participants free of sleep problems at baseline. Frequent deadlines were cross-sectionally and longitudinally associated with poorer sleep quality on all three sleep quality measures. Associations in the longitudinal analyses were greatly attenuated when we adjusted for baseline sleep quality. The logistic regression analyses showed that frequent deadlines at baseline were associated with elevated odds ratios for caseness of sleep problems at follow-up, however, confidence intervals were wide in these analyses. Frequent deadlines at work were associated with poorer sleep quality among Danish knowledge workers. We recommend investigating the relation between deadlines and health endpoints in large-scale epidemiologic studies.

Nocturnal Asthma Symptoms and Poor Sleep Quality Among Urban School Children with Asthma

Objective The aim of this study was to describe nocturnal asthma symptoms among urban children with asthma and assess the burden of sleep difficulties between children with varying levels of nocturnal symptoms. Methods We analyzed baseline data from 287 urban children with persistent asthma (aged 4–10 years) enrolled in the School-Based Asthma Therapy trial; Rochester, New York. Caregivers reported on nocturnal asthma symptoms (number of nights/2 weeks with wheezing or coughing), parent quality of life (Juniper’s Pediatric Asthma Caregivers Quality of Life Questionnaire), and sleep quality by using the validated Children’s Sleep Habits Questionnaire. We used bivariate and multivariate statistics to compare nocturnal asthma symptoms with sleep quality/quantity and quality of life. Results Most children (mean age, 7.5 years) were black (62%); 74% had Medicaid. Forty-one percent of children had intermittent nocturnal asthma symptoms, 23% mild persistent, and 36% moderate to severe. Children's average total sleep quality score was 51 (range, 33–99) which is above the clinically significant cutoff of 41, indicating pervasive sleep disturbances among this population. Sleep scores were worse for children with more nocturnal asthma symptoms compared with those with milder symptoms on total score, as well as several subscales, including night wakings, parasomnias, and sleep disordered breathing (all P < .03). Parents of children with more nocturnal asthma symptoms reported their child having fewer nights with enough sleep in the past week ( P = .018) and worse parent quality of life ( P < .001). Conclusions Nocturnal asthma symptoms are prevalent in this population and are associated with poor sleep quality and worse parent quality of life. These findings have potential implications for understanding the disease burden of pediatric asthma.

Sleep quality and job satisfaction of Turkish nurses

This research was conducted as a descriptive study for the purpose of examining nurses' sleep quality, job satisfaction, and the relationship between them. The research population was comprised of nurses who work at Inönü University Turgut Ozal Medical Center (Turkey) and the research was conducted with a total of 418 nurses. A Personal Information Form, developed by the researchers based on information in the literature, and the Pittsburgh Sleep Quality Index (PSQI) and Short Form Minnesota Satisfaction Questionnaire (MSQ), which have been adapted for Turkish and had validity and reliability studies conducted, were used for data collection in the research. For data analysis, frequency distribution, arithmetic mean, variance analysis (One-Way ANOVA), Tukey test, and Independent Samples t test were used. According to the findings obtained from the research it was determined that nurses' total sleep quality score mean was 7.28 +/- 3.56 and job satisfaction score mean was 48.05 +/- 11.77 and a weak negative correlation was found between the 2 tools (r = -0.25) (P < .05). As the nurses' sleep quality increased (that is, as their sleep quality score mean decreased) their job satisfaction increased (their job satisfaction score mean increased). In general, the results obtained from our research show that nurses' sleep quality is low and their job satisfaction is at a moderate level. In parallel with this, as the nurses' sleep quality decreases their job satisfaction also decreases.

Zaleplon Improves Sleep Quality in Maintenance Hemodialysis Patients

Background/Aim: A recent survey has shown that insomnia is still a very common problem in maintenance hemodialysis (MHD) patients. The aim of the present study was to test the effects of zaleplon (ZAL), a new nonbenzodiazepine hypnotic drug, on the sleep quality of MHD patients with insomnia. Methods: The sleep quality was assessed by the Pittsburgh questionnaire in 10 patients (6 males/4 females) with insomnia on MHD; these patients underwent a randomized double-blind crossover study versus placebo (PLA). The main exclusion criterion was the presence of any possible cause of insomnia related to other concurrent diseases. Results: Treatment with ZAL significantly improved the total score of sleep quality (p < 0.03 vs. PLA). The analysis of the single components revealed that treatment with ZAL was associated with a higher subjective sleep quality (p < 0.01 vs. PLA) and a reduced sleep latency (p < 0.01 vs. PLA). The duration of sleep was not modified by ZAL, whereas a significant improvement was detected in habitual sleep efficacy (p < 0.05 vs. PLA). No peculiar side effect was recorded on ZAL. Blood parameters did not change, nor were differences recorded in the dialysis parameters (body weight gain, blood pressure) throughout the study. Conclusions: This study suggests that ZAL has a positive effect on the sleep quality in MHD patients. The absence of side effects and its pharmacodynamic properties make ZAL a useful drug in uremic patients.
