Abstract
STUDY OBJECTIVES Although associations between sleep quality and environmental factors and nutrient intake have been reported, interactions between these factors have not been elucidated in detail. Therefore, this cross-sectional study examined the effects of regular exercise and nutrient intake on sleep quality using the Pittsburgh Sleep Quality Index (PSQI), which is the most frequently used index for sleep evaluation. METHODS The participants included 378 individuals aged 40 years or older living in Shika Town, Ishikawa Prefecture. Of these individuals, 185 met the inclusion criteria. The participants completed a self-administered questionnaire assessing lifestyle habits and frequency and duration of exercise, the PSQI, and the brief-type self-administered diet history questionnaire (BDHQ) on nutrient intake. RESULTS A two-way analysis of covariance on regular exercise and PSQI scores indicated that protein intake (17.13% of energy) was significantly higher in the regular exercise and PSQI ≤10 groups than in the non-regular exercise or PSQI ≥11 groups (p = 0.002). In a multiple logistic regression analysis with PSQI scores (≤10 and ≥11), protein intake was a significant independent variable in any of the models adjusted for confounding factors such as age, sex, body mass index, current smoker, and current drinker (OR: 1.357, 95% CI: 1.081, 1.704, p = 0.009) in the regular exercise group but not in the non-regular exercise group.Conclusions We identified a positive relationship between sleep quality and protein intake in the regular exercise group. These findings suggest that regular exercise at least twice a week for 30 minutes or longer combined with high protein intake contributes to good sleep quality.

Effects of Cognitive Behavioral Therapy for Insomnia on Subjective-Objective Sleep Discrepancy in Patients with Primary Insomnia: a Small-Scale Cohort Pilot Study. Int J Behav Med 2021; 28:715-726. [PMID: 33629218 DOI: 10.1007/s12529-021-09969-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/11/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Cognitive behavioral therapy for insomnia (CBT-I) is a first-line therapy for insomnia disorders. We assessed changes in discrepancies between subjective and objective sleep measures and correlations between discrepancy changes and clinical insomnia severity for CBT-I in patients with primary insomnia METHODS: Fifty-two outpatients (mean age, 60.3 years; 26 women) with primary insomnia were treated by individual CBT-I (50 min, maximum six sessions, once every 1-2 weeks). One week before and after CBT-I, patients recorded a sleep log and wore an actigraphy device. Subjective and objective time in bed (TIB), total sleep time (TST), sleep-onset latency (SOL), wake time after sleep onset (WASO), and sleep efficiency (SE) were evaluated by averaging 1-week records. Relative values of sleep discrepancy in TIB, TST, SOL, WASO, and SE were calculated for estimating effects of CBT-I. The therapeutic effects were also evaluated using psychological scales before and after CBT-I. RESULTS Subjective and objective discrepancies in sleep measures decreased by 36, 25, and 37 min in TST, SOL, and WASO, respectively, and 7% in SE (all P < 0.001) after CBT-I. Seven patients transitioned from underestimating SE before CBT-I to overestimating SE after CBT-I. Although CBT-I improved relative values of discrepancy in WASO and SE, alongside ISI, the improvement in insomnia severity only correlated with SOL discrepancy. CONCLUSIONS CBT-I may reduce the discrepancy between subjective and objective sleep measures in patients with primary insomnia. However, a greater therapeutic effect of CBT-I was observed in reducing the ISI, which was slightly influenced by improvements in sleep discrepancies.

Impact of improvement of sleep disturbance on symptoms and quality of life in patients with functional dyspepsia. BMC Gastroenterol 2021; 21:78. [PMID: 33602148 PMCID: PMC7890897 DOI: 10.1186/s12876-021-01659-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 02/04/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND/AIMS Functional dyspepsia (FD) is often comorbid with sleep disturbance. However, it is not fully understood how sleep disturbance affects the pathophysiology of FD. We aimed to investigate the relationship between FD and sleep disturbance. METHODS We prospectively enrolled 20 FD patients with sleep disturbance between December 2018 and July 2019. Patients took sleep aids for 4 weeks and filled out questionnaires before and after taking sleep aids. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Athens Insomnia Scale (AIS) were used to evaluate the severity of their sleep disturbance. Modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (mFSSG), Gastrointestinal Symptom Rating Scale (GSRS), and the Japanese version of Patient Assessment of Constipation Quality of Life (JPAC-QOL) were used to evaluate the severity of GI symptoms. Short-Form 36-Item Health Survey (SF-36) was used to evaluate QOL. Pre- and post-sleep medication values of questionnaires were compared. RESULTS Among 20 enrolled patients, 16 completed the study protocol. Zolpidem, eszopiclone, and suvorexant were administered to six, nine, and one patient, respectively. Each median total score of questionnaires (pre-/post-sleep medication, respectively) was as follows: PSQI, 10.0/8.5; ESS, 12.5/5.0; AIS, 10.0/4.0; mFSSG, 21.0/16.0; GSRS, 44.0/31.0 (Pain in GSRS, 11.0/5.0); JPAC-QOL, 26.0/15.5; SF-36, 63.9/71.9. All of these results showed statistically significant differences between pre- and post-sleep medication (p < 0.05). CONCLUSIONS Improvement of sleep disturbance by administration of sleep aids resulted in improvement of GI symptoms and QOL in patients with FD. This effect may be related to pain modification.

Abstract
BACKGROUND Psychosocial factors significantly influence patient care in many fields of medicine, among these in the field of endocrinology. Easily applicable validated assessment tools for such psychosocial factors are lacking. Visual instruments may facilitate doctor-patient communication. This study describes the development and validation of a multidimensional visual tool for the self-assessment of health. METHODS An expert panel performed the multistep development of the psychosomatic assessment health disc (PAHD). Assessment of face validity was performed by means of a focus group of medical doctors (n = 6) and patient interviews (n = 24). For determining test-retest reliability, internal consistency and construct validity, patients of an endocrine outpatient clinic in Graz, Austria, completed the PAHD and the following questionnaires: short-form 36 health survey, work ability index, Pittsburgh sleep quality index and the social life scales of the life satisfaction questionnaire. RESULTS A numeric six-item analogue scale was developed in the form of a disc. It addresses the following aspects of health: physical well-being, social life, sexuality, mental well-being, sleep, working ability/performance. For the validation process, 177 patients (57.1% females) participated in the study. Correlation coefficients of the six items with other questionnaires ranged between r = 0.51 (social life) and r = 0.72 (sleep). Test-retest reliability was assessed among 98 patients and was ≥ 0.74 for all 6 items, while Cronbach's alpha was 0.78. CONCLUSION The psychometric properties of the PAHD support its use in clinical encounters with patients suffering from endocrine disorders. Further validation studies may be required to extend its application to other fields of medicine.

Abstract
OBJECTIVE This study sought to validate the Japanese version of the Sleep Hygiene Practices Scale (SHPS-J). PATIENTS/METHODS A cross-sectional questionnaire-based study was conducted via the internet. In total, 854 participants (435 men, 419 women; mean age, 42.91 ± 11.54 years) were asked to complete all scales, and 283 of them were asked to complete the same scales two weeks later. The survey consisted of the SHPS-J, the Japanese version of the Insomnia Severity Index (ISI-J), and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). The SHPS-J was developed according to the International Society for Pharmacoeconomics and Outcomes Research Task Force for Translation and Cultural Adaption. For the analysis, participants were divided into three groups: insomnia syndrome, insomnia symptoms, and good sleep groups. RESULTS The SHPS-J had good test-retest reliability (ICC: 0.55-0.76) and adequate internal consistency (α = 0.54-0.74), except with regard to eating/drinking behaviors. The factorial validity of the four-factor structure was confirmed through a confirmatory factor analysis; however, one item related to eating/drinking behaviors had no significant factor loading. The construct validity was confirmed through a correlation analysis between each domain of the SHPS-J and ISI-J (r = 0.19-0.60, p < 0.01). The results of clinical validation confirmed that all domains of the SHPS-J were significantly higher for individuals with insomnia than for good sleepers. CONCLUSIONS This study confirmed both the reliability and validity of the SHPS-J.

Abstract
BACKGROUND & AIMS Improving sleep quality is important for an aging society. However, no study has been conducted on the association between dietary variety and sleep efficiency among older Japanese adults using longitudinal data. The current study is a longitudinal study that aimed to elucidate the association between dietary variety and sleep efficiency in older Japanese adults. METHODS This study was conducted among older adults (≥70 years old in 2016) in the metropolitan area of Tokyo, Japan, between 2016 and 2018. Dietary variety score (DVS) and sleep efficiency were determined for all participants and were used to assess dietary habits and sleep quality, respectively. A cross-lagged panel analysis was used to consider the prospective associations between DVS and sleep efficiency, and this analysis was performed before and after adjusting for possible covariates in the 2016 data. RESULTS After adjusting for age, sex, body mass index, current drinking status, current smoking status, exercise habits, living (alone or with others) style, the Japanese version of the Geriatric Depression Scale (Short Form), sleep duration and retiring time the DVS in 2016 predicted the sleep efficiency in 2018 (β = 0.130, p < 0.05). CONCLUSION The possibility that DVS can predict sleep efficiency 2 years later was demonstrated.

Abstract
OBJECTIVES Although exercise improves sleep parameters in older people, most studies have been designed for people with insomnia or sleep complaints. Little is known of the effects of exercise among older people without sleep problems. We investigated the effects of 3-month light-to-moderate intensity aerobic exercise intervention on objectively measured sleep quantity and quality among community-dwelling older people. METHODS Fifty-eight community-dwelling older people were assigned into an exercise (EX) or control (CON) groups, and 49 participants (65.7 ± 5.7 years. BMI 24.4 ± 3.9 kg/m2) were enrolled in the analysis. EX group members attended 60 min/week group-based exercise program and performed ≥140 min of home-based exercise, at ≥50% of maximum heart rate to exceed 200 min of total exercise per week. Sleep was assessed by an accelerometer and the Pittsburgh Sleep Quality Index (PSQI) before and after intervention. RESULTS In the EX group, total sleep time, hours in waking after sleep onset, sleep efficiency and consecutive wake episodes ≥10 min (WE≥10 min) significantly improved (p<0.05). EX group showed a significantly greater reduction in WE≥10 min than the CON group (p<0.05). The subgroup analyses in the EX group according to baseline PSQI cutoff value showed no differences in changes between subgroups. CONCLUSIONS Three-month aerobic exercise improved objectively measured sleep quality in community-dwelling older people. Baseline sleep conditions did not significantly influence the magnitude of changes in sleep quality and quantity. These results suggest that light aerobic exercise can improve sleep among community-dwelling older people, regardless of baseline sleep status, but the effect may be small.

Abstract
BACKGROUND Depression and anxiety are common mental health problems that are strongly associated with sleep disturbances, according to community-based researches. However, this association has not been investigated among patients admitted for cardiovascular diseases (CVDs). We examined the prevalence of depression and anxiety in inpatients with various CVDs and their association with sleep disturbances. MATERIALS AND METHODS This cross-sectional study included 1294 patients hospitalized for CVDs in a Japanese university hospital were evaluated for their mental status using the Hospital Anxiety and Depression Scale (HADS), for sleep-disordered breathing (SDB) using pulse oximetry, and for sleep quality using the Pittsburgh Sleep Quality Index (PSQI). RESULTS Patient characteristics were as below: mean age, 63.9±14.7 years; 25.7% female. Overall, 18.9% had depression (HADS-depression≥8) and 17.1% had anxiety (HADS-anxiety≥8). The presence of depression was associated with female sex, older age, higher plasma brain natriuretic peptide level, lower estimated glomerular filtration rate, and the prevalence of heart failure. Overall, 46.5% patients were categorized as having a poor sleep quality (PSQI>5), and 28.5% patients had SDB (3% oxygen desaturation index>15). Although depression and anxiety were not associated with SDB, they were independently associated with poor sleep quality (OR = 3.09, 95% CI 2.19-4.36; OR = 3.93, 95% CI 2.71-5.69, respectively). CONCLUSIONS Depression and anxiety were not uncommon in patients with CVDs. Poor sleep quality could be an important risk factor linked to psychological disturbances.

Functional capacity was assessed using the social role subscale, included in the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC). Multiple regression analyses were performed using social roles as dependent variables and age, body mass index, HbA1c, glycoalbumin/HbA1c, hypertension, dyslipidemia, diabetic microangiopathy, cardiovascular disease, depression, sleep disturbance, living alone, frailty, diabetic drug as explanatory variables. RESULTS In total, 367 patients (208 males and 159 females) were included. In men, diabetic nephropathy (coefficient, -0.496; 95% confidence interval (CI), -0.900 to -0.091; P = 0.017), depression (coefficient, -0.497; 95% CI, -0.942 to -0.051; P = 0.029), and frailty (coefficient, -0.595; 95% CI, -1.048 to -0.142; P = 0.010) were associated with a decline in social roles. In women, frailty (coefficient, -0.826; 95% CI, -1.306 to -0.346; P = 0.001) was associated with a decline in social roles. CONCLUSIONS Social roles may decline in elderly male diabetic patients with nephropathy, depression, and frailty and in elderly female diabetic patients with frailty.

Magnetic Resonance Spectroscopy in the Ventral Tegmental Area Distinguishes Responders to Suvorexant Prior to Treatment: A 4-Week Prospective Cohort Study. Front Psychiatry 2021; 12:714376. [PMID: 34497544 PMCID: PMC8419448 DOI: 10.3389/fpsyt.2021.714376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Accepted: 07/31/2021] [Indexed: 11/13/2022] Open
Abstract
Background: The ventral tegmental area (VTA; a dopaminergic nucleus) plays an important role in the sleep-wake regulation system including orexin system. In addition to neuronal activity, there is increasing evidence for an important role of glial cells (i.e., astrocytes and microglia) in these systems. The present study examined the utility of magnetic resonance spectroscopy (MRS) for detecting neural and/or glial changes in the VTA to distinguish responders from non-responders before treatment with the orexin receptor antagonist suvorexant. Methods: A total of 50 patients were screened and 9 patients were excluded. The remaining 41 patients with insomnia who have or not a psychiatric disease who were expected to receive suvorexant treatment were included in this study. We compared MRS signals in the VTA between responders to suvorexant and non-responders before suvorexant use. Based on previous reports, suvorexant responders were defined as patients who improved ≥3 points on the Pittsburgh Sleep Quality Index after 4 weeks of suvorexant use. MRS data included choline (reflects non-specific cell membrane breakdown, including of glial cells) and N-acetylaspartate (a decrease reflects neuronal degeneration). Results: Among 41 examined patients, 20 patients responded to suvorexant and 21 patients did not. By MRS, the choline/creatine and phosphorylcreatine ratio in the VTA was significantly high in non-responders compared with responders (p = 0.039) before suvorexant treatment. There was no difference in the N-acetylaspartate/creatine and phosphorylcreatine ratio (p = 0.297) between the two groups. Conclusions: Changes in glial viability in the VTA might be used to distinguish responders to suvorexant from non-responders before starting treatment. These findings may help with more appropriate selection of patients for suvorexant treatment in clinical practice. Further, we provide novel possible evidence for a relationship between glial changes in the VTA and the orexin system, which may aid in the development of new hypnotics focusing on the VTA and/or glial cells.

FAAH and CNR1 Polymorphisms in the Endocannabinoid System and Alcohol-Related Sleep Quality. Front Psychiatry 2021; 12:712178. [PMID: 34566715 PMCID: PMC8458733 DOI: 10.3389/fpsyt.2021.712178] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Accepted: 08/09/2021] [Indexed: 12/02/2022] Open
Abstract
Sleep disturbances are common among individuals with alcohol use disorder (AUD) and may not resolve completely with short-term abstinence from alcohol, potentially contributing to relapse to drinking. The endocannabinoid system (ECS) is associated with both sleep and alcohol consumption, and genetic variation in the ECS may underlie sleep-related phenotypes among individuals with AUD. In this study, we explored the influence of genetic variants in the ECS (Cannabinoid receptor 1/CNR1: rs806368, rs1049353, rs6454674, rs2180619, and Fatty Acid Amide Hydrolase/FAAH rs324420) on sleep quality in individuals with AUD (N = 497) and controls without AUD (N = 389). We assessed subjective sleep quality (from the Pittsburgh Sleep Quality Index/PSQI) for both groups at baseline and objective sleep efficiency and duration (using actigraphy) in a subset of individuals with AUD at baseline and after 4 weeks of inpatient treatment. We observed a dose-dependent relationship between alcohol consumption and sleep quality in both AUD and control groups. Sleep disturbance, a subscale measure in PSQI, differed significantly among CNR1 rs6454674 genotypes in both AUD (p = 0.015) and controls (p = 0.016). Only among controls, neuroticism personality scores mediated the relationship between genotype and sleep disturbance. Objective sleep measures (sleep efficiency, wake bouts and wake after sleep onset), differed significantly by CNR1 rs806368 genotype, both at baseline (p = 0.023, 0.029, 0.015, respectively) and at follow-up (p = 0.004, p = 0.006, p = 0.007, respectively), and by FAAH genotype for actigraphy recorded sleep duration at follow-up (p = 0.018). These relationships suggest a significant role of the ECS in alcohol-related sleep phenotypes.

Abstract
BACKGROUND Presenteeism is the loss of work productivity of workers owing to physical and mental problems, and its socioeconomic effects are greater than those of absenteeism. Presenteeism is caused by psychological and physical dysfunctions. On the other hand, the regularity of mealtimes is an important factor associated with physical and mental health conditions. We hence assessed the association among the irregularity of mealtimes, presenteeism, psychological and physical stress responses, and sleep disturbance in office workers in companies. METHODS From May to December 2017, the data of 2905 participants who had given their consent to use their information for academic purposes, and answered a questionnaire about the survey and their lifestyle were collected. Path analysis was performed to analyze the association between the irregularity of mealtimes, psychosomatic symptoms (Brief Job Stress Questionnaire), sleep disturbance (Pittsburgh Sleep Questionnaire), and presenteeism (Work Limitations Questionnaire). RESULTS The direct effect of the irregularity of mealtimes on presenteeism was significant but weak. However, the irregularity of mealtimes had a strong effect on presenteeism indirectly through psychological and physical stress responses and sleep disturbance. CONCLUSION Psychological and physical stress responses and sleep disturbance were identified as mediating factors of the effects of irregularity of mealtimes on presenteeism.

Abstract
BACKGROUND Patients with obstructive sleep apnea syndrome (OSAS) experience excessive daytime sleepiness and insomnia and they are at risk of developing cardiovascular disease and stroke. Continuous positive airway pressure therapy could improve symptoms and decrease these risks; however, adherence is problematic. Although the oral appliance is another therapeutic option, patient satisfaction is limited and the effect of the nasal airway stent - a new device - remains unclear. OBJECTIVES The aim of this study was to evaluate the effect of NAS therapy in patients with mild-to-moderate OSAS in a prospective, single-arm, interventional pilot study. METHOD Patients with mild/moderate sleep apnea (n = 71; Apnea-Hypopnea Index [AHI], 5-20 events/h on polysomnography) were recruited. Sleep-associated events were measured using a portable device (WatchPAT200) pre- and immediately post-treatment and at 1 month follow-up. AHI (including supine and non-supine AHI), Oxygen Desaturation Index (ODI), Respiratory Disturbance Index (RDI), percutaneous oxygen saturation, heart rate, and snore volume were evaluated. Symptoms were assessed using the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and Hospital Anxiety and Depression Scale. RESULTS NAS use significantly improved AHI, supine AHI, RD, ODI, and snore volume compared to pre-intervention (r = 0.44, 0.48, 0.3, 0.42, and 0.34; p < 0.001, p < 0.001, p = 0.011, p < 0.001, and p = 0.048, respectively). Additionally, 25 and 10% of patients showed complete and partial response for AHI, respectively; these improvements remained significant 1 month later. Pittsburgh Sleep Quality Index scores improved from 6.0 to 5.3 (r = 0.46, p = 0.022). CONCLUSIONS NAS therapy reduced severity and snoring in patients with mild-to-moderate OSAS. Approximately 30% of patients did not tolerate NAS due to side effects.

Abstract
The objective of this randomized, double-blind, placebo-controlled, crossover study was to examine the effects of onion extract containing concentrated cysteine sulfoxides on improving sleep quality. In total, 30 healthy men and women who were dissatisfied with their sleep consumed the test food sample (onion extract tablets) for 5 days. The delta power during non-rapid eye movement sleep and the delta power per minute in the first sleep cycle increased significantly with the intake of onion extract containing concentrated cysteine sulfoxides compared with the intake of placebo. A significant decline in sleep latency was also observed. Salivary α-amylase level, a stress indicator, decreased significantly with the intake of onion extract containing concentrated cysteine sulfoxides compared with the intake of placebo. These findings indicate that onion extract containing concentrated cysteine sulfoxides alleviates stress, improves the quality of sleep and promotes smooth transition into sleep.

Abstract
This study aimed to assess the efficacy and safety of self-designed Ningxin Anshen (NXAS) Formula for post-ischemic stroke insomnia of blood-deficient and liver-heat syndrome. Ninety patients were randomized into NXAS group, Placebo group and Zopiclone group. Patients in the NXAS group, Placebo group and Zopiclone group were treated with Ningxin Anshen Formula, placebo and zopiclone for 4 weeks, respectively. The scores of the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI) and traditional Chinese Medicine (TCM) Syndromes of self-designed scale and the number of adverse events (AEs) were determined. Results showed that the overall effective rate in the NXAS group and Placebo group was 76.67 and 30.00%, respectively, showing significant difference (P < 0.01). There was no marked difference between Zopiclone group (80.00%) and NXAS group. In both NXAS group and Zopiclone group, the scores of PSQI, ISI, and TCM Syndromes of self-designed scale after 4-week treatment were significantly different from those before treatment (P < 0.01). After 4-week treatment, the scores of PSQI, ISI, and TCM Syndromes of self-designed score were comparable between NXAS group and Zopiclone group (P > 0.05). Only one patient in the NXAS group developed gastrointestinal discomfort, which resolved without treatment discontinuation. In conclusion, self-designed NXAS Formula is effective and safe and has little adverse effect in treating post-stroke insomnia of blood-deficient and liver-heat syndrome.

Distinct effects of low-intensity physical activity in the evening on sleep quality in older women: A comparison of exercise and housework. Exp Gerontol 2020; 143:111165. [PMID: 33232794 DOI: 10.1016/j.exger.2020.111165] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 11/03/2020] [Accepted: 11/18/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND The effects of intensity, type, and time of day of physical activity on sleep are not well understood. An appropriate increase in core body temperature, due to physical activity during daytime, aids sleep in older adults. Our previous study showed that evening exercise has more positive effects on sleep quality in older adults when compared with morning exercise. However, older adults who do not exercise form a large part of the population. This study aimed to examine the distinct effects of low-intensity exercise and housework during the evening on sleep quality in older women. METHODS This randomized crossover study included 10 healthy older women aged 65-79 years. The participants engaged in low-intensity physical activity for 30 min, either aerobic exercise (70 steps per minute), housework (at the same intensity), or remained sedentary (control) 3 h before bedtime. Sleep was recorded polysomnographically, and self-reported sleep quality was assessed the next morning using the Oguri-Shirakawa-Azumi sleep inventory, Middle-Aged and Aged version (OSA-MA) questionnaire. RESULTS Compared with the control trial, core body temperature was significantly elevated in participants after each activity trial (0.5 ± 0.4 and 0.4 ± 0.4 °C for housework and aerobic exercise, respectively). There was a significant difference in sleep latency (14.2 ± 19.1, 9.9 ± 15.6, and 4.2 ± 3.5 min for control, housework, and aerobic exercise, respectively; ANOVA P = 0.011) among the trials. The delta power density after aerobic exercise was significantly higher than that after the control trial. We observed an increase of 53% and 15% in delta power during the 1st hour of sleep as a result of aerobic exercise and housework, respectively. The total score on OSA-MA was significantly higher after aerobic exercise (91.0 ± 5.4, 88.1 ± 6.9, and 108.6 ± 5.9 points for control, housework, and exercise, respectively). CONCLUSIONS Engaging in low-intensity aerobic exercise in the evening improved polysomnographic and self-reported sleep quality. Although housework increased core body temperature to the same level as that observed after aerobic exercise, self-reported sleep quality after housework was lower than that after aerobic exercise.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Persian Medicine (TPM) has been established as a valuable source of medicinal plants for the treatment of insomnia for thousands of years. Accordingly, oil extracts from plants' parts have been widely used to alleviate central nervous system (CNS) ailments including sleep disorders. A number of preparations have been recommended by TPM for the treatment of insomnia. Among them, an intranasal formulation containing oily macerates of Viola odorata L., Crocus sativus L. and Lactuca sativa L. stands out. AIM OF THE STUDY In the present double-dummy, double-blind placebo controlled clinical trial, we aim to evaluate the effectiveness of a combination of violet oil, saffron oil, and lettuce seeds oil nasal drop compared with the placebo (sesame oil). MATERIALS AND METHODS Fifty patients with primary chronic insomnia were randomly assigned in TPM-treatment or placebo groups, received either two drops of the herbal oil or placebo into each nostril every noon and evening for 8 weeks. Before the study commencement and after 1, 4 and 8 weeks of treatment, Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) questionnaires were completed by all patients. The primary outcome measure was considered as any changes in ISI scores between the first visit and after 8 weeks. Changes in PSQI scores during the study and possible side effects were also assessed. The multicompound herbal oil was standardized using HPLC analysis and contained 0.02 mg/mL crocin and 4 μg/mL isoquercitrin. RESULTS Our study revealed a significant reduction in the ISI and PSQI scores from baseline by the study endpoint (P ≤ 0.01). The mean ISI scores in week 8 decreased significantly for the intervention group (P = 0.001) and also the placebo group (P < 0.01) when compared with baseline. Moreover, the use of hypnotic drugs in the intervention group was significantly reduced (P < 0.001), while in the control group was maintained at baseline level. CONCLUSIONS It seems that intranasal use of the multi-herbal preparation can be used to improve chronic insomnia and to reduce the dose of conventional hypnotic medications in insomniac patients.

Abstract
OBJECTIVE The present study clarified the prevalence and risk factors of sleep disorders in visually impaired athletes. METHODS A cross-sectional questionnaire survey was conducted with 99 visually impaired athletes engaged in the following Paralympic sport events: track and field (marathon), goalball, swimming, blind soccer, and judo. Eighty-one respondents (male: 72.8%; average age: 32.5 ± 12.0 years) who completed the survey were chosen for analyses. Survey items were attributes [age, gender, body mass index, and condition of visual impairment (athletic classification and causing time of disability)], lifestyle habits (bedtime, wake-up time, drinking alcohol, meals, and use of electronics after lights out), competition activities (sports time per week, morning and evening practices, and competition stressors), psychological distress, and sleep disorders [recorded using the Pittsburgh Sleep Quality Index (PSQI)]. First, the prevalence of the respondents having sleep disorders (scored 5.5 points or more in the PSQI) was investigated. Then, the relations between attributes, lifestyle habits, competition activities, psychological distress, and sleep disorders were explored using logistic regression analysis. RESULTS Twenty-six respondents (32.1%) had sleep disorders. Results of multivariate logistic regression analysis showed that "interpersonal relationship stressors" and "wake-up time" were independently related to sleep disorders. CONCLUSIONS Approximately one-third of visually impaired athletes were shown to have sleep disorders. High interpersonal relationship stressors and late wake-up time may be risk factors of their sleep disorders.

Abstract
Background Sleeping pills are widely used for sleep disorders and insomnia. This population-based study aimed to evaluate the association between the use of sleeping pills and metabolic syndrome (MetS) and metabolic components in an apparently healthy Japanese cohort. Methods We examined baseline cross-sectional data from the JMS-II Cohort Study. The criteria for MetS and its components were based on The National Cholesterol Education Program Adult Treatment Panel III. Sleep habits including the sleep duration of the subjects and the frequency of sleeping pill use were obtained using The Pittsburgh Sleep Quality Index questionnaire. For different sleep durations, the association between sleeping pill use and MetS was assessed. Odds ratios (ORs) and their 95% confidence intervals (CIs) were estimated using multiple logistic regression models to quantify this association. Results Our study included 6,153 individuals (mean age, 63.8 [standard deviation 11.2] years), and 3,348 (54.4%) among them were women. The association between sleep duration and MetS was an inverted J-shaped curve among sleeping pill users and a J-shaped curve among non-users. After adjustment for various confounders, less than 6 h of sleep among sleeping pill users was associated with increased rates of MetS (<6 h, OR 3.08; 95% CI, 1.29–7.34]). The frequency of sleeping pill use in individuals with short sleep duration showed a positive association with the prevalence of MetS and its components. Conclusions Sleeping pill users with a short sleep duration had a 3-fold higher chance of having MetS than non-users with a short sleep duration.

A detection method for latent circadian rhythm sleep-wake disorder. EBioMedicine 2020; 62:103080.

Abstract
BACKGROUND Individuals with typical circadian rhythm sleep-wake disorders (CRSWDs) have a habitual sleep timing that is desynchronized from social time schedules. However, it is possible to willfully force synchronisation against circadian-driven sleepiness, which causes other sleep problems. This pathology is distinguishable from typical CRSWDs and is referred to here as latent CRSWD (LCRSWD). Conventional diagnostic methods for typical CRSWDs are insufficient for detecting LCRSWD because sufferers have an apparently normal habitual sleep timing. METHODS We first evaluated the reliability of circadian phase estimation based on clock gene expression using hair follicles collected at three time points without sleep interruption. Next, to identify detection criteria for LCRSWD, we compared circadian and sleep parameters according to estimated circadian phases, at the group and individual level, between subjects with low and high Pittsburgh Sleep Quality Index (PSQI) scores. To validate the reliability of identified detection criteria, we investigated whether the same subjects could be reproducibly identified at a later date and whether circadian amelioration resulted in sleep improvement. FINDINGS We successfully validated the reliability of circadian phase estimation at three time points and identified potential detection criteria for individuals with LCRSWD attributed to delayed circadian-driven sleepiness. In particular, a criterion based on the interval between the times of the estimated circadian phase of clock gene expression and getting out of bed on work or school days was promising. We also successfully confirmed the reproducibility of candidate screening and sleep improvement by circadian amelioration, supporting the reliability of the detection criteria. INTERPRETATION Although several limitations remain, our present study demonstrates a promising prototype of a detection method for LCRSWD attributed to delayed circadian-driven sleepiness. More extensive trials are needed to further validate this method. FUNDING This study was supported mainly by JSPS, Japan.

Abstract
OBJECTIVE We aimed at investigating factors associated with social isolation and being homebound in older patients with diabetes. DESIGN Cross-sectional study. SETTINGS Those undergoing outpatient treatments at Ise Red Cross Hospital, Mie Prefecture. PARTICIPANTS Patients with diabetes aged ≥65 years. PRIMARY AND SECONDARY OUTCOME MEASURES Social isolation was defined as indulging in less than one interaction per week with individuals other than cohabiting family members. We defined homebound as going outside home less than once a day. To identify factors associated with social isolation and being homebound, we performed logistic regression analysis. The dependent variable was social isolation or homebound and independent variables were basic attributes, glycaemic parameters, complications and treatment details. RESULTS We analysed 558 cases (320 men and 238 women). Among these, 174 (31.2%) were socially isolated; meanwhile, 87 (15.6%) were homebound. The glycoalbumin/haemoglobin A1c ratio (OR 4.52; 95% CI 1.07 to 19.1; p=0.040) and the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) scores (OR 0.72; 95% CI 0.57 to 0.90; p=0.006) had significant associations with social isolation. TMIG-IC scores (OR 0.78; 95% CI 0.66 to 0.92; p=0.003) and insulin use (OR 4.29; 95% CI 1.14 to 16.1; p=0.031) were associated with being homebound. CONCLUSION In older patients with diabetes, glycaemic fluctuations and insulin use are associated with social isolation and being homebound, respectively. In addition, a decline in higher level functional capacity is a common factor associated with social isolation and being homebound. Thus, it is important to pay attention to social isolation and being homebound when a decline in higher level functional capacity, increased glycaemic fluctuations and insulin use in older patients with diabetes are observed.

Abstract
OBJECTIVE Nasal obstruction is considered to be one of the risk factors for obstructive sleep apnea, together with a high arched narrow palate, elongated uvula, malocclusion, and tongue and tonsil size. The impact of nasal obstruction on sleep apnea is controversial, however, and its relation to sleep quality is rarely discussed. The purpose of this study was to investigate the independent effect of nasal obstruction on sleep quality. METHODS Sixty-nine patients with nasal obstructive symptoms and without sleep apnea episodes were enrolled from September 2018 to August 2019, and compared before and after surgery with thirty-four patients who had benign diseases of the thyroid or parathyroid as a control group, to investigate effects of surgery. Sleep quality was evaluated using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). All cases were reassessed at three months after surgery. RESULTS The postoperative PSQI scores in the nasal surgery group were significantly lower than the preoperative scores (p < 0.001). In contrast, there was no statistically significance difference between the pre- and postoperative PSQI scores in the neck surgery group. Difference of PSQI scores before and after surgery in the nasal surgery group was significantly higher than the neck surgery group. CONCLUSIONS This double-arm study suggests that reduction of nasal disfunction with nasal surgery contributes significantly to sleep quality, in patients who may not have noticed their impaired quality of sleep previously because of their long-term nasal symptoms.

Abstract
INTRODUCTION Neither the pathophysiology nor an effective treatment for heart failure with preserved ejection fraction (HFpEF) has been elucidated to date. The purpose of this ongoing study is to elucidate the pathophysiology and prognostic factors for patients with HFpEF admitted to participating institutes. We also aim to obtain insights into the development of new diagnostic and treatment methods by analysing patient background factors, clinical data and follow-up information. METHODS AND ANALYSIS This study is a prospective, multicentre, observational study of patients aged ≥20 years admitted due to acute decompensated heart failure with preserved left ventricular ejection fraction (≥50%) and elevated N-terminal-pro brain natriuretic peptide (NT-proBNP) (≥400 pg/mL). The study began in June 2016, with the participation of Osaka University Hospital and 31 affiliated facilities. We will collect data on history in detail, accompanying diseases, quality of life, frailty score, medication history, and laboratory and echocardiographic data. We will follow-up each patient for 5 years, and collect outcome data on mortality, cause of death, and the number and cause of hospitalisation. The target number of registered cases is 1500 cases in 5 years. ETHICS AND DISSEMINATION The protocol was approved by the Institutional Review Board (IRB) of Osaka University Hospital on 24 February 2016 (ID: 15471), and by the IRBs of the all participating facilities. The findings will be disseminated through peer-reviewed publications and conference presentations.

The effect of short or long sleep duration on quality of life and depression: an internet-based survey in Japan. Sleep Med 2020; 76:80-85. [PMID: 33120132 DOI: 10.1016/j.sleep.2020.10.012] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 09/17/2020] [Accepted: 10/13/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND To date, no previous studies have evaluated the relationship between sleep duration and quality of life (QOL) or depression in the general population after controlling for daytime sleepiness and sleep disturbances. METHODS A web-based cross-sectional survey was conducted with 8698 subjects aged 20-69 years. We examined the relationships between weekday sleep duration and daytime sleepiness, sleep disturbance, QOL and depression, using the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index (without the item for sleep duration), 8-item Short Form and Center for Epidemiological Studies Depression Scale (CES-D). RESULTS Daytime sleepiness tended to increase in proportion to shorter weekday sleep durations. Sleep disturbances, physical and mental QOL, and CES-D scores were worse in both the shorter and longer sleep groups compared with the group with 7-8 h of sleep. Hierarchical logistic regression analyses revealed that short sleep duration but not long sleep duration was significantly associated with reduction of both physical and mental QOL, even after controlling for the presence of daytime sleepiness and sleep disturbance. Both short and long sleep duration were independently and significantly correlated with depression after controlling for daytime sleepiness; however, there was no statistically significant association after adjusting for the effects of sleep disturbance. CONCLUSIONS The results suggested adverse effects of short sleep but not long sleep on both physical and mental QOL. In addition, the negative impact of specific types of sleep disturbance on depression may be greater than the impact of shortening of sleep duration.

Abstract
The purpose of this study was to investigate the changes in patient subjective happiness and satisfaction with cataract surgery and evaluate the association between satisfaction and types of cataract. This study surveyed 247 participants (mean age, 67.9 years) and they completed questionnaires on their satisfaction with the surgery, the subjective happiness scale (SHS) and the Pittsburgh Sleep Quality Index (PSQI) before and after surgery. The SHS increased postoperatively from 4.6 ± 0.7 to 4.8 ± 0.7 (P = 0.007) and 83.4% of patients were satisfied with the surgical results and the average satisfaction score was 4.2 out of a possible 5.0. Multiple regression analysis showed that patient satisfaction was significantly associated with the postoperative SHS (β = 0.380; P < 0.001), the postoperative PSQI (β = −0.041; P = 0.035) and the presence of a posterior subcapsular cataract (PSC) (β = 0.277; P = 0.026). This study clarified that cataract surgery may improve both visual function and patient happiness and that patient satisfaction was affected by postoperative sleep quality and the disappearance of a PSC.

Abstract
Euglena gracilis EOD-1, a kind of microalgae, is known to contain a high proportion of paramylon, a type of β-1,3-glucan. Paramylon derived from E. gracilis EOD-1 is presumed to suppress cellular oxidative injury and expected to reduce fatigue and fatigue sensation. Therefore, we aimed to examine whether food containing paramylon derived from E. gracilis EOD-1 (EOD-1PM) ingestion reduced fatigue and fatigue sensation in healthy adults. We conducted a randomized, double-blind, placebo-controlled, parallel-group comparison study in 66 healthy men and women who ingested a placebo or EOD-1PM daily for 4 weeks (daily life fatigue). Furthermore, at the examination days of 0 and 4 weeks, tolerance to fatigue load was evaluated using mental tasks (task-induced fatigue). We evaluated fatigue sensation using the Visual Analogue Scale, the work efficiency of the advanced trail making test and measured serum antioxidant markers. The EOD-1PM group showed significantly lower levels of physical and mental fatigue sensations and higher levels of work efficiency as well as serum biological antioxidant potential levels than the placebo group. These results indicate that EOD-1PM ingestion reduced fatigue and fatigue sensation, which may be due to an increase in antioxidant potential and maintenance of selective attention during work.

Abstract
Premenstrual symptoms are common problems among female high-school and college athletes. This prospective study investigated associations between sleep habits and interference of premenstrual symptoms in athletic performance among Japanese adolescent athletes. A school-based survey on menstruation and school life was conducted among 623 female high-school students in 2015 and 2016, and data from the two surveys were connected. In total, 262 students completed the questionnaire in both years. We recruited 108 of those students who were athletes with regular menstrual cycles. Participants completed a questionnaire about their premenstrual symptoms and lifestyle habits. The prevalence of short sleep duration (<8 h) was high (95.4%). The difference in premenstrual symptom severity in individual students between the first and second years was not significant (p > .05). Premenstrual symptoms were less associated with disturbance in 'athletic performance in training or competition' in the second year than the first. 'Longer sleeping time' in the first year was associated with lower risk of increased interference of premenstrual symptoms in athletic performance in the second year (odds ratio 0.982, 95% confidence interval: 0.970-0.994). Shorter sleep duration may therefore have an effect on premenstrual symptoms' interference with athletic performance among Japanese adolescents.

Abstract
OBJECTIVES Prior literature has documented the global burden of serious mental illnesses. The present study aimed to compare the sleep quality in caregivers of older patients with schizophrenia spectrum and bipolar disorders with control participants who did not serve as caregivers. METHODS We performed a case-controlled, cross-sectional study among family caregivers of older patients with psychotic disorders in Razi Hospital, Tunisia. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index Scale (PSQI). RESULTS Fifty caregivers of older patients (≥ 60 years) with schizophrenia spectrum and bipolar disorders, and 50 matched controls were enrolled. The three sub-dimensions of the PSQI, namely subjective sleep quality, sleep duration, and sleep efficiency, as well as overall PSQI scores, were worse for caregiver participants. Hierarchical multiple regression analyses predicting PSQI scores revealed that caregivers' age and marital status were the only significant predictors in the final model. CONCLUSIONS Older adults with severe mental disorders constitute a vulnerable population which generates a significant burden of care, and impacts their caregivers' subjective sleep quality. CLINICAL IMPLICATIONS Family interventions, including sleep interventions, should be considered as an integral component of treatment for serious mental illnesses. When promoting sleep quality, older and single caregivers should be targeted.

Abstract
Background Mental health disorders can disrupt a person’s sleep, resulting in lower quality of life. Early identification and referral to mental health services are critical for active duty service members returning from forward-deployed missions. Although technologies like wearable computing devices have the potential to help address this problem, research on the role of technologies like Fitbit in mental health services is in its infancy. Objective If Fitbit proves to be an appropriate clinical tool in a military setting, it could provide potential cost savings, improve clinician access to patient data, and create real-time treatment options for the greater active duty service member population. The purpose of this study was to determine if the Fitbit device can be used to identify indicators of mental health disorders by measuring the relationship between Fitbit sleep data, self-reported mood, and environmental contextual factors that may disrupt sleep. Methods This observational cohort study was conducted at the Madigan Army Medical Center. The study included 17 healthy adults who wore a Fitbit Flex for 2 weeks and completed a daily self-reported mood and sleep log. Daily Fitbit data were obtained for each participant. Contextual factors were collected with interim and postintervention surveys. This study had 3 specific aims: (1) Determine the correlation between daily Fitbit sleep data and daily self-reported sleep, (2) Determine the correlation between number of waking events and self-reported mood, and (3) Explore the qualitative relationships between Fitbit waking events and self-reported contextual factors for sleep. Results There was no significant difference in the scores for the pre-intevention Pittsburg Sleep Quality Index (PSQI; mean 5.88 points, SD 3.71 points) and postintervention PSQI (mean 5.33 points, SD 2.83 points). The Wilcoxon signed-ranks test showed that the difference between the pre-intervention PSQI and postintervention PSQI survey data was not statistically significant (Z=0.751, P=.05). The Spearman correlation between Fitbit sleep time and self-reported sleep time was moderate (r=0.643, P=.005). The Spearman correlation between number of waking events and self-reported mood was weak (r=0.354, P=.163). Top contextual factors disrupting sleep were “pain,” “noises,” and “worries.” A subanalysis of participants reporting “worries” found evidence of potential stress resilience and outliers in waking events. Conclusions Findings contribute valuable evidence on the strength of the Fitbit Flex device as a proxy that is consistent with self-reported sleep data. Mood data alone do not predict number of waking events. Mood and Fitbit data combined with further screening tools may be able to identify markers of underlying mental health disease.

Psychometric Testing of the Premenstrual Symptoms Questionnaire and the Association Between Perceived Injustice and Premenstrual Symptoms: A Cross-Sectional Study Among Japanese High School Students. Int J Womens Health 2020; 12:755-763. [PMID: 33061664 PMCID: PMC7524195 DOI: 10.2147/ijwh.s269392] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 08/28/2020] [Indexed: 01/05/2023] Open
Abstract
Purpose Premenstrual symptoms comprise a wide range of mood, behavioral, and physical symptoms occurring during the luteal phase. Perceived injustice is a belief linked to unfairness (ie, unnecessary suffering caused by illness). This study aimed to assess the validity and reliability of the Premenstrual Symptoms Questionnaire (PSQ), a patient-reported outcome measurement tool, and to examine the association between perceived injustice/perception of menstruation and premenstrual symptoms, as measured by the PSQ. Materials and Methods Of 1388 female students, we analyzed 879 students with regular menstrual cycles who completed the PSQ, the premenstrual dysphoric disorder (PMDD) scale, the Somatic Symptom Scale-8 (SSS-8), and the Injustice Experience Questionnaire-chronic (IEQ-chr). First, the PSQ was examined for evidence of reliability and validity. Next, we used multiple regression and multivariate logistic regression to investigate the association between perceived injustice and premenstrual symptoms, using PSQ score as both a continuous variable and a dichotomous variable (premenstrual disorders or not). Moreover, the association between PSQ score and perceived menstruation was tested using student's t-test and analysis of variance. Results In terms of reliability, Cronbach's α for PSQ score was 0.93. To assess structural validity, we used confirmatory factor analysis, which showed that the one-factor model and the two-factor model were a good fit. The PSQ showed good agreement with the PMDD scale. In terms of concurrent validity, PSQ total score correlated strongly with PMDD scale score, SSS-8 score, and IEQ-chr score (r = 0.88, 0.69, 0.57, respectively). IEQ-chr score predicted PSQ score (standardized regression coefficient = 0.53; P < 0.0001) and higher prevalence of premenstrual disorders (odds ratio: 1.15; 95% confidence interval: 1.12-1.19). Negative perception of menstruation was associated with premenstrual symptoms. Conclusion The PSQ showed sound psychometric properties among the adolescents in our sample. Perceived injustice and negative perception of menstruation were associated with premenstrual symptoms.

Abstract
Previously, we found that a Japanese diet was associated with psychological status, and a combination of rice and miso was related to mental and physical health. We hypothesized that the intake of a rice-based diet affected mental and physical health and aimed to investigate the consequences of a dietary intervention with rice. We conducted a randomized, open-label, parallel-group clinical trial that included 60 participants, who were randomly assigned to receive either rice-based meals or meals with other cereals for three daily meals over 2 months. The participants were surveyed for psychological status and biochemical changes. Sleep quality index scores showed significant improvement after the rice-based intervention. Additionally, blood oxidative stress levels were reduced in the rice-diet group compared with the no-rice-diet group. Although the molecular mechanisms should be investigated in detail, our findings suggest that controlling oxidative stress through the intake of a rice-centered diet may be key to improving sleep quality.

Abstract
OBJECTIVES Early palliative care reportedly contributes to the quality of life by improving coping skills in patients with cancer. The aims of the study are to (1) Build a self-coping system that makes it possible to perform a session of home-based heart rate variability biofeedback (HRV-BF) with resonant breathing in patients with sleep disturbance and to acquire its techniques early on, and (2) Examine its short-term efficacy and feasibility. METHODS A randomised, open-label, comparative study was conducted in the presence or absence of home-based HRV-BF with resonant breathing using a portable HRV-BF device prior to bedtime. The participants were 50 patients with incurable cancer with sleep disturbance who underwent a hospital practice of HRV-BF with resonant breathing. The primary end point was the rate of change in sleep efficiency for 10-14 days. The Japanese version of the Pittsburgh Sleep Quality Index (subjective indicator) and actigraphy sleep parameters (objective indicators) were used for sleep assessments. RESULTS The completion rate and implementation rate in the home-based HRV-BF group (n=25) were 96.0% and 91.4%, respectively. This group showed a significant improvement in sleep efficiency, sleep duration and the low-frequency component of HRV. Sleep latency worsened in this group, but a significant difference was not observed. CONCLUSIONS A home practice of HRV-BF with resonant breathing made it possible to acquire its techniques early on and improve sleep and autonomic function; therefore, our study showed high short-term efficacy and feasibility required for a self-coping system.

Abstract
Objective It is well known that poor sleep increases the risk of heart failure (HF). However, the underlying mechanisms remain unclear. In this study, we investigated the association of poor sleep with hemodynamic stress on the left ventricle, which was a key factor for the development of HF in elderly individuals. Methods A total of 2,301 participants (≥65 years old) without cardiac disease were enrolled in this cross-sectional analysis. We evaluated the subjective sleep quality, sleeping difficulty, subjective sleep duration, use of sleeping pills, and daytime dysfunction using the Pittsburgh Sleep Quality Index, a 19-item self-reported questionnaire. We assessed serum N-terminal pro-brain natriuretic peptide (NT-proBNP) as a marker of hemodynamic stress on the left ventricle, and we defined high NT-proBNP as a serum NT-proBNP level ≥ 125 pg/mL. Results Sleeping difficulty was significantly associated with high NT-proBNP levels [odds ratio (OR), 1.46; 95% confidence interval (CI), 1.16-1.85; p<0.005]. A subjective short sleep duration was also significantly associated with high NT-proBNP levels (OR, 1.69; 95% CI, 1.03-2.75; p<0.05). A subjective poor sleep quality, the use of sleeping pills, and daytime dysfunction were not associated with serum NT-proBNP levels. All data were adjusted for the age, sex, body mass index, serum hemoglobin concentration, serum creatinine level, systolic blood pressure, diastolic blood pressure, and use of antihypertensive medications. Conclusion Poor sleep was associated with high hemodynamic stress to the left ventricle in elderly population.

Abstract
BACKGROUND The increase in the number of Internet users has increased Internet dependence worldwide. In adolescents, this dependence may interfere with sleep, which is important for the development of psychophysiological capabilities. However, few large-scale surveys have described the relationship between Internet addiction (IA) and sleep disturbance using standardized questionnaires. We conducted a survey in one prefecture in Japan to determine the relationship between sleep disturbance and IA in adolescents based on the categories of the Young Diagnostic Questionnaire (YDQ). METHODS In 2016, high school students (N = 10,405, age range: 15-16 years) in all 54 daytime high schools in the selected prefecture were surveyed using a self-administered questionnaire. Participants with scores > 5.5 points on the Japanese version of the Pittsburgh Sleep Quality Index were defined as having a sleep disturbance. IA was evaluated using the YDQ: Participants with five to eight YDQ items present were classified as having IA; those with three or four items present were classified as "at risk of IA"; and those with two or less YDQ items were classified as "non-IA". Multiple logistic regression analysis was performed with sleep disturbance as the dependent variable, IA as the explanatory variable, and adjustments for eight other variables. RESULTS High YDQ scores were associated with a high prevalence of sleep disturbance in boys and girls. These findings persisted after controlling for other factors in the multiple regression model. CONCLUSIONS Among Japanese adolescents, there was a significant independent relationship between IA and sleep disturbance.

Abstract
We aimed to investigate the association in frailty and sleep disorder as assessed by the Japanese version of Pittsburgh Sleep Quality Index (PSQI-J) in patients with chronic liver diseases (CLDs, n = 317, 141 males). Frailty was determined using the following five phenotypes: unintentional body weight loss, self-reported exhaustion, muscle weakness, slow walking speed, and low physical activity. Sleep disorder was defined as patients with PSQI-J score 6 or greater. Robust (phenotype, 0), prefrail (1 or 2 phenotypes) and frailty (3 phenotypes or greater) were observed in 101 (31.9%), 174 (54.9%) and 42 (13.2%), respectively. The median (interquartile range (IQR)) PSQI-J score was 4 (3, 7). Sleep disorder was found in 115 patients (36.3%). The median (IQR) PSQI-J scores in patients of the robust, prefrail, and frail groups were 3 (2, 5), 5 (3, 7), and 8 (4.75, 10.25), respectively (p < 0.0001 between any two groups and overall p < 0.0001). The ratios of sleep disorder in patients with robust, prefrail and frailty were 15.8% (16/101), 39.1% (68/174), and 73.8% (31/42), respectively (overall p < 0.0001). In conclusion, CLD patients with frailty can involve poorer sleep quality. As sleep disorder in CLDs is potentially remediable, future frailty-preventive strategies must take sleep complaints into account.

Abstract
Methods In this cross-sectional study, 315 medical students chosen by stratified random sampling participated in the academic year 2018-2019. The Pittsburgh Instrument and DASS-21 questionnaire were used to evaluate sleep quality and anxiety, depression, and stress, respectively. Also, demographic, educational, and socioeconomic information was collected. SPSS 16 software was used for data analysis. Results Out of 300 students who completed the questionnaires, 165 (55%) were male, with a mean age of 21.94 ± 2.28 years old. The prevalence of poor sleep quality was 51.3%. We did not find significant associations among age, sex, and poor sleep quality. Concurrent psychological symptoms such as stress, depression, and anxiety were significantly associated with sleep disorders. After adjusting variables in the multivariable regression model, depression (OR = 2.81, 95% CI: 1.35-5.87; p = 0.006) and the number of hours spent on using smartphones in 24 hours (OR = 1.13, 95% CI: 1.02-1.25; p = 0.01) were significantly associated with poor sleep quality among medical students. Conclusion The prevalence of poor sleep quality among medical students was high, and we found that increased use of smartphones during the day and depression were associated with sleep disorders.

Abstract
Literature reports suggest that subjective sleep quality is associated with nutrient intake in elderly people and workers. However, few studies have suggested an association between objective sleep quality and dietary intake in adolescents and young women. We hypothesized that objective sleep quality is associated with dietary intake in adolescents and young women. We evaluated the association between energy and nutrient intake and objective sleep quality in adolescents and young Japanese women. In a cross-sectional study of 80 women aged 18-27 years, dietary intake was assessed using the self-administered diet history questionnaire. Objective sleep quality was assessed by actigraphy. Lifestyle characteristics, dietary habits, and mental health were assessed using specific questionnaires. Subjects were classified into 3 groups according to sleep efficiency (SE <80%, 80%-85%, and ≥85%), and the relationships between dietary intake and objective sleep quality were statistically evaluated. No significant differences occurred in lifestyle characteristics, physical activity levels, eating behavior, and mental health status among the 3 SE groups. Energy intake was significantly lower in the low-SE group than in the middle- (P = .004) and high- (P = .015) SE groups. Protein intake was significantly lower in the low-SE group than in the high-SE group (P = .034). The mean energy-adjusted intakes of vitamin K, vitamin B2, potassium, magnesium, iron, zinc, copper, and tryptophan were significantly lower in the low-SE group than in the high-SE group. Adequate energy intake and a high-quality diet including vitamins, minerals, and tryptophan may result in high sleep quality and help prevent sleep problems.

Abstract
STUDY OBJECTIVES Social jetlag, a mismatch between biological and social timing, has been reported to be associated with depressive symptoms among general population. However, evidence on this association is lacking among non-shift workers, who are under pressure to adapt themselves to a work schedule. We investigated the cross-sectional association of social jetlag with depressive symptoms among Japanese non-shift workers. METHODS This study included 1,404 employees, aged 18-78 years, who completed a study questionnaire at a periodic health checkup. Social jetlag was calculated as the absolute value of the difference in the midpoint of sleep times between weekdays and weekends. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Multivariable logistic regression was used to estimate the odds ratio (OR) with adjustments for potential confounders including diet and chronotype. RESULTS Of the study participants, 63.5%, 28.4%, and 8.1% had less than 1 hour, 1 to less than 2 hours, and at least 2 hours of social jetlag, respectively. Greater social jetlag was significantly associated with an increased likelihood of having depressive symptoms. The multivariable-adjusted OR (95% confidence interval) were 1.30 (0.95 to 1.78) and 2.14 (1.26-3.62) for 1 to less than 2 hour and at least 2 hours compared to less than 1 hour of social jetlag. The association between social jetlag and depressive symptoms appeared to be linear, according to restricted cubic spline regression. CONCLUSION Results suggest that greater social jetlag is associated with an increased likelihood of having depressive symptoms among non-shift workers.

Setyowati A, Chung MH. Validity and reliability of the Indonesian version of the Pittsburgh Sleep Quality Index in adolescents. Int J Nurs Pract 2020; 27:e12856. [PMID: 32632973 DOI: 10.1111/ijn.12856] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 08/01/2019] [Accepted: 05/02/2020] [Indexed: 12/01/2022]
Abstract
AIM The study aims to examine the psychometric properties of the Pittsburgh Sleep Quality Index-Indonesian version. BACKGROUND The Pittsburgh Sleep Quality Index has never been translated into Bahasa. DESIGN This study employs a cross-sectional and correlational study. METHODS Data were collected from 528 adolescents of junior high school age (13-16 years) during August to September 2014. All participants agreed on the Indonesian version of Pittsburgh Sleep Quality Index and Beck Depression Inventory-II. Psychometric properties were examined including internal consistency, construct validity and known group validity, and the receiver operating characteristic curve was used to measure the cut-off point. RESULTS The Cronbach's alpha for the Pittsburgh Sleep Quality Index-Indonesian version was adequate. There were positive correlations between the total score and seven component scores. Construct validity revealed that the total score of the Pittsburgh Sleep Quality Index-Indonesian version was correlated with the total score of the Indonesian version of the Beck Depression Inventory-II. Known group validity indicated that adolescents without depression risk had better sleep quality. According to receiver operating characteristic curve analysis, the cut-off point at a score of 6.5 indicated the best possible relationship of sensitivity and specificity. CONCLUSION The Pittsburgh Sleep Quality Index-Indonesian version has high reliability and validity for screening sleep quality among adolescents.

The evaluation of recumbent reflux by multichannel intraluminal impedance pH testing for patients with gastroesophageal reflux disease and sleep disturbance. Esophagus 2020; 17:348-354. [PMID: 31970574 DOI: 10.1007/s10388-020-00717-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 01/12/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIM The relationship between gastroesophageal reflux disease (GERD) and sleep disturbance has recently been pointed out and is garnering substantial attention. Although there are reports that point out the effectiveness of medical treatment for sleep disturbance associated with GERD, examinations of the pathological condition, including reflux during sleep, are inadequate. In the present study, we evaluated the recumbent reflux in patients with GERD and sleep disturbance using multichannel intraluminal impedance pH (MII-pH), and attempted to suppress recumbent reflux by surgical treatment to examine the pathophysiology of patients with GERD and sleep disturbance. MATERIALS AND METHODS Of the 47 patients with GERD-related diseases in whom laparoscopic fundoplication was performed at The Jikei University Hospital from January 2016 to June 2017, 31 patients (average age: 55.9 ± 13.8 years, male in 25), excluding 9 with surgical indications only for esophageal hiatal hernia and 7 without postoperative evaluation, were the subjects of this study. All surgical procedures were performed by the Toupet method. We used the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep disturbance, setting 5.5 as the cut-off value, based on the report by Doi et al., with any conditions beyond this value deemed sleep disturbance. The evaluation of gastroesophageal reflux was carried based on the MII-pH using the Sleuth, manufactured by Sandhill Corporation, with an automatic analysis carried out by computer. Furthermore, recumbent abnormal reflux was defined as recumbent all reflux (times) > 7. All evaluations were performed preoperatively and at 3 months after the operation. The data were expressed in medians and interquartile ranges, with p < 0.05 defined as statistically significant by the Mann-Whitney, Wilcoxon, or Chi-squared test. RESULTS Although sleep disturbance was found in 19 cases (61%), 8 (42%) of which were actually confirmed as nighttime abnormal reflux, of whom 5 cases (63%) showed significant improvement in their sleep disturbance following the operation, with a PSQI score of lower than 5.5. Among these 5 cases, postoperative recumbent abnormal reflux was also significantly reduced as compared with the preoperative condition (17 vs. 2 times/day, p = 0.042). Furthermore, sleep disturbance improved and recumbent abnormal reflux also decreased in two cases, with sleep disturbance improved by controlling the nighttime reflux via surgery in a total of 7 cases (87.5%). Although the PSQI score was as high as 14 points before and after the operation in one case, the rate of recumbent abnormal reflux was remarkably reduced, with sleep disturbance and recumbent reflux considered irrelevant. Furthermore, regarding the frequency of recumbent acid/non-acid reflux, while non-acid reflux was significantly more frequent in the patients with recumbent reflux complications (9 vs. 1 time/day, p < 0.001), there was no marked difference in the frequency of acid reflux. CONCLUSIONS Among cases with GERD and sleep disturbance, approximately one-third of them showed findings suggestive of the involvement of recumbent reflux in sleep disturbance, with reflux characterized by non-acid reflux.

Abstract
PURPOSE The benefits of respite care in reducing the burden of caregivers of children with disabilities are well known; however, few studies have effectively quantified such benefits. The aim of the present study was to develop and validate a measure for evaluating the benefit of respite care provided to family caregivers of children with disabilities. DESIGN AND METHODS This was a cross-sectional study. We distributed a survey questionnaire to 465 family caregivers between March and April 2017. Participants were asked to respond to items regarding benefits of respite care for themselves and their children. RESULTS Data in relation to four domains (Child Development, Sense of Peace and Life Fulfillment among Caregivers, Mental Health Support for the Caregiver, and Expansion of Perspectives and Future Vision) were extracted to assess the benefits of using respite care. The full-scale Cronbach's α coefficient was 0.89 and ranged between 0.73 and 0.88 for each individual domain. CONCLUSIONS The newly developed measure for assessing the benefits of respite care for family caregivers of children with disabilities was highly reliable and valid. PRACTICE IMPLICATIONS This objective tool would allow healthcare practitioners to review the quality of respite care they provide and subsequently help them identify ways to improve.

Abstract
AIM Several studies have reported a negative correlation between depressive symptoms and family caregivers' (FCs) subjective sleep status. However, there is a paucity of information on the association between objective/subjective sleep status, care burden, and related factors. METHODS Participants were 23 pairs of care receivers (CRs; Mage = 82.7 ± 8.5 years; 69.6% women) receiving long-term care at home and their FCs (Mage = 66.9 ± 11.0 years; 69.6% women). At baseline, demographic data, subjective sleep status (Pittsburgh Sleep Quality Index; PSQI), WHO-5 well-being, depressive mood, and frequency of going outdoors were collected. FCs wore a small, wrist-worn device with an accelerometer to assess objective sleep status for a consecutive 24-h 2-week period, and they answered the Zarit Burden Interview short version (ZBI) every night before sleep. After 3 months, CR status was collected and analysed retrospectively. RESULTS The mean total sleep time over 2 weeks was 349.5 ± 69.6 min. The mean ZBI score over 2 weeks was 8.8 ± 6.8, which was significantly correlated with total sleep time (r = -0.42; P < 0.05), total time in bed (r = -0.44; P < 0.05), PSQI (r = 0.62; P < 0.01), frequency of going outdoors by CRs (r = -0.42; P < 0.05), and WHO-5 well-being among CRs (r = -0.50; P < 0.05). Multiple regression analyses revealed that total sleep time (β = -0.51; P < 0.05) was significantly associated with care burden (adjusted R2 = 0.45). At the 3-month follow-up, four CRs had been hospitalised or died, and their FCs displayed significantly severe care burden and slept less than at baseline. CONCLUSIONS Reduced objective total sleep time is significantly associated with the severity of care burden among FCs. Home-based care is critical in Japan; therefore, it is meaningful to determine how to reduce care burden.

Sleep Quality, Anxiety, and Depression Are Associated with Fall Risk Factors in Older Women. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4043.

Abstract
Gait, dynamic balance, and functional mobility problems are well-known fall risk factors. Furthermore, sleep disturbances, anxiety, and depression are prevalent among older women. This study aimed to analyze the associations of sleep quality, anxiety, and depression with functional mobility, gait speed, and dynamic balance in community-dwelling postmenopausal women aged ≥ 60 years. A total of 271 women (69.18 ± 5.69 years) participated in this study. Functional mobility (Timed Up-and-Go Test), dynamic balance (3-meter tandem walk test), gait speed (OptoGait® optical detection system), sleep quality (Pittsburgh Sleep Quality Index), and anxiety and depression (Hospital Anxiety and Depression Scale) were assessed. Our results showed that poor sleep efficiency and the use of sleeping medication were related to decreased gait speed (R2 = 0.072). Poor functional mobility was linked to depression and the use of sleeping medication (R2 = 0.159). Additionally, increased symptoms of anxiety and depression were associated with worsened dynamic balance (R2 = 0.127). In conclusion, poorer sleep quality is associated with slower gait speed and reduced functional mobility, which is also related, along with impaired dynamic balance, to higher levels of anxiety and depression.

Ubiquinol-10 Intake Is Effective in Relieving Mild Fatigue in Healthy Individuals. Nutrients 2020; 12:nu12061640. [PMID: 32498248 PMCID: PMC7352232 DOI: 10.3390/nu12061640] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 05/20/2020] [Accepted: 05/28/2020] [Indexed: 12/13/2022] Open
Abstract
Our double-blind, placebo-controlled study evaluated effects of ubiquinol, the reduced form of coenzyme Q10, on mild fatigue in healthy individuals experiencing fatigue in daily life that had continued for more than 1 and less than 6 months. The participants received 100-mg/day (Ubq100; age 44.0 ± 9.8 years; 14 females and 6 males) or 150-mg/day ubiquinol (Ubq150; age 40.4 ± 11.8 years; 14 females and 8 males) or placebo (Plc; age 41.3 ± 13.4 years; 13 females and 7 males) daily for 12 weeks. Measurements of subjective and objective fatigue were conducted by using questionnaires-based fatigue scales/visual analogue scales and autonomic nerve function/biological oxidation index, respectively, prior to the first dosing and every 4 weeks thereafter. Serum ubiquinol level increased three- to four-fold after 4 weeks and remained significantly higher than that after Plc administration throughout the intake period. Although a higher blood level of ubiquinol was observed with Ubq150 than with Ubq100, the difference was not statistically significant. In both Ubq100 and Ubq150 groups, subjective levels of fatigue sensation and sleepiness after cognitive tasks, which consisted of the modified Advanced Trail Making Test, the modified Stroop Color-Word Test, and the Digit Symbol Substitution Test, improved significantly compared with those in the placebo group, suggesting an anti-fatigue effect. The Ubq150 group demonstrated significant improvement compared with the Plc group regarding subjective level of relaxation after task, sleepiness before and after task, motivation for task, and serum level of oxidative stress. Correlation analysis between blood level of ubiquinol and each evaluated effect suggested a positive relationship with relaxation after task, motivation for cognitive task, and parasympathetic activity. The results of the study suggest that ubiquinol intake relieves mild fatigue in healthy individuals.

Abstract
Background Little is known about cognitive and behavioral predictors of sleep quality and relapse among individuals with alcohol use disorder (AUD). Using the social cognitive theory (SCT), we assessed sleep-related behaviors and cognitions, sleep quality, and relapse to drinking among individuals with AUD transitioning from inpatient to outpatient settings. Method Individuals (n = 149) seeking treatment for AUD were recruited during their inpatient stay. Self-efficacy for sleep, dysfunctional beliefs about sleep, sleep-related behaviors, sleep quality, and relapse were assessed. Objective (actigraphy) assessment of sleep efficiency and duration was measured using actigraphy. Multiple logistic regression models tested whether self-reported sleep quality or sleep-related beliefs/behavior predicted relapse. Repeated measures linear mixed modeling tested whether there was a change over time in sleep quality as well as the relationships between self-efficacy, sleep-related beliefs, sleep behaviors, sleep quality, and relapse. Results In our sample, self-efficacy for sleep, dysfunctional beliefs about sleep, and sleep-related behavior were all significantly associated with both sleep quality and relapse. Controlling for pre-discharge sleep-related behaviors (SRBQ) and actigraphy-recorded average sleep time during the first week post-discharge, married participants had lower odds of relapse compared with non-married patients (p = 0.048, OR = 0.119, 95% CI 0.015–0.983). Patients with lower self-efficacy for sleep (SES) scores (p < 0.001) and higher CPRS anxiety scores (p < 0.001) had higher PSQI scores. Conclusion Our results highlight the importance of self-efficacy and dysfunctional beliefs about sleep as predictors of sleep quality and relapse among individuals with AUD and the utility of the SCT as a sleep research framework.

Abstract
PURPOSE Poor quality of sleep is a common feature in patients with various lung diseases and affects their health-related quality of life (HRQL). We evaluated sleep quality and HRQL in patients on the waitlist for lung transplantation in Japan. METHODS In this prospective study, patient-reported and physiological data were collected from patients newly registered on the waitlist for lung transplantation in Japan. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) and HRQL using the St. George's Respiratory Questionnaire (SGRQ). The frequency of poor sleep quality, correlations between sleep quality and various clinical parameters, and predictive factors of sleep quality were examined. RESULTS Of 193 patients, the three most-frequent indications for lung transplantation were interstitial pneumonia (n = 96), pulmonary complications of hematopoietic stem cell transplantation (n = 25), and pulmonary hypertension (n = 17). Poor sleep quality (PSQI > 5) was observed in 102 patients (53%) and was significantly associated with worse Hospital Anxiety and Depression Score (HADS), worse SGRQ score, worse modified Medical Research Council Dyspnea score, and shorter 6-min walk distance. However, it was not associated with sex, pulmonary function, interstitial pneumonia, or arterial blood gas. Stepwise multiple regression analysis indicated that poor sleep quality was explained significantly by HADS anxiety (23%) and SGRQ Symptoms (10%). CONCLUSION Poor sleep quality was found to be common among patients on the lung transplantation waitlist in Japan. The two most significant factors responsible for impaired sleep quality were anxiety and respiratory symptoms. Additional care should be taken to ensuring a better quality of sleep for such patients.

Abstract
PURPOSE Poor sleep quality has been reported to be a risk factor for cardiovascular disease, diabetes, and metabolic syndrome, as well as mental disorders including depression and anxiety. However, few studies have investigated the association between sleep quality and diet in young males. We aimed to assess this association, adjusting for psychological factors. METHODS In this study, a total of 124 male Japanese students were analyzed. Sleep quality, diet, and psychological symptoms were assessed using self-reported questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), brief-type self-administered diet history questionnaire (BDHQ), 12-item General Health Questionnaire (GHQ12), and State-Trait Anxiety Inventory (STAI) A-Trait scale. RESULTS Among participants, 40% exhibited a PSQI total score ≥ 6, indicating poor sleep quality. Poor sleep quality was associated with poor mental health status and higher levels of anxiety. After adjusting for covariates including these psychological factors, poor sleep quality was significantly associated with low intakes of fat, beta-carotene, retinol, alpha-tocopherol, vitamin K, vitamin B1, daidzein, genistein, and iron. Poor sleep quality was also associated with low intake of pulses, fat and oil, as well as high intakes of sugar-sweetened beverages. CONCLUSIONS Our findings demonstrated that sleep quality among young Japanese males was associated with specific dietary features, independently of psychological status, which may help to elucidate the mechanisms underlying the link between sleep and sleep-related diseases.
