Previous research has found that elite athletes have insufficient sleep, yet the specific kinds of sleep disturbances occurring as compared to a control group are limited. Here we compare the subjective sleep quality and chronotype of elite athletes to a control group of non-athlete good sleepers. Sixty-three winter Canadian National Team athletes (mean age 26.0 ± 0.0; 32% females) completed the Pittsburgh Sleep Quality Index (PSQI) and the Athlete Morningness Eveningness Scale. They were compared to 83 healthy, non-athlete, good-sleeper controls (aged 27.3 ± 3.7; 51% females) who completed the PSQI and the Composite Scale of Morningness. The elite athletes reported poorer sleep quality (PSQI global score 5.0 ± 2.6) relative to the controls (PSQI global score 2.6 ± 1.3), despite there being no group difference in self-reported sleep duration (athletes 8.1 ± 1.0 h; controls 8.0 ± 0.7 h). Further, athletes’ chronotype distribution showed a greater skew toward morningness, despite there being no group differences in self-reported usual bedtime and wake time. These results suggest that a misalignment of sleep times with circadian preference could contribute to poorer sleep quality in elite athletes.

Background: Some accident victims report poorer sleep during the months after the trauma, which may double the risk for and is a mediator of the development of a PTSD. Furthermore, subjective and objective sleep measures are often discrepant in PTSD-patients, which is why a ‘sleep state misperception’ of PTSD patients is often hypothesized. Objective: The goal of this study is to assess differences in sleep quality in victims of a traffic accident compared to healthy participants without an accident history as well as differences between objective and subjective sleep quality measures. Methods: We recruited 25 hospitalized accident victims within ten days of an accident and 31 age and sex-matched controls without an accident history. Three months later, participants were given a structured clinical interview (SCID), they completed the Pittsburg Sleep Quality Index (PSQI) for the previous two weeks, wore a wrist actigraph, and kept a sleep log for two consecutive nights. Results: At the three-month follow-up, none of the victims met the criteria for any kind of mental disorder, but scored higher on the Posttraumatic Diagnostic Scale. On the PSQI they reported slightly worse sleep than controls for the previous two weeks, although sleep log and actigraphy measures on the two recording nights showed no group differences. Actigraphy measures showed shorter sleep onset latencies compared to log measures. Conclusions: The accident victims suffered only minimal sleep disturbances three months later. The assumption of a ‘sleep state misperception’ in traffic accident victims is questioned by these results.

Background: Sleep disturbances are very common among elderly population and mostly remain incurable. Practical, brief, and effective interventions are needed to promote sleep quality in older adults with moderate sleep disturbances. This study aimed to investigate the effectiveness of a brief behavioral training program in ameliorating sleep quality in older adults suffering from moderate sleep disturbances. Materials and Methods: This study was conducted on 64 older adults with moderate sleep disturbances, as defined by Pittsburgh Sleep Quality Index (PSQI) score ≥5. Participants were randomly allocated to either intervention (n=32) or control (n=32) group. Older adults in the intervention group received a brief behavioral-based sleep training program which was delivered in a single in-person session followed by four telephone sessions during 4 weeks. While their peers in the control group did not receive any intervention. The main outcome of the study was scores on the PSQI which was compared at pre- and post-intervention between both groups. Data were analyzed using the SPSS software version 19.0. Results: At 4 weeks, PSQI scores decreased in older adults receiving intervention, as compared with the scores of participants to the control group (P<0.001). Subjects in the intervention group also showed significant improvements in sleep latency, subjective sleep quality, sleep duration, and sleep efficiency (P<0.05). Conclusion: Brief behavioral interventions may be promising and useful for older adult population with moderate problems, and can be considered an efficacious and non-invasive intervention approach to improve elderly’s sleep quality.

Background: Time restricted feeding (TRF) involves deliberately restricting the times during which energy is ingested. Preliminary findings suggest that 8–10-h TRF improves sleep. However, the effects of shorter TRF windows (4–6 h) on sleep, remain unknown. Aims: This study compared the effects of 4-h versus 6-h TRF on sleep quality, duration, insomnia severity and the risk of obstructive sleep apnea. Methods: Adults with obesity ( n = 49) were randomized into one of three groups: 4-h TRF (eating only between 3 and 7 p.m.), 6-h TRF (eating only between 1 and 7 p.m.), or a control group (no meal timing restrictions) for 8 weeks. Results: After 8 weeks, body weight decreased ( p < 0.001) similarly by 4-h TRF (–3.9 ± 0.4 kg) and 6-h TRF (–3.4 ± 0.4 kg), versus controls. Sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI), did not change by 4-h TRF (baseline: 5.9 ± 0.7; week 8: 4.8 ± 0.6) or 6-h TRF (baseline: 6.4 ± 0.8; week 8: 5.3 ± 0.9), versus controls. Wake time, bedtime, sleep duration and sleep onset latency also remained unchanged. Insomnia severity did not change by 4-h TRF (baseline: 4.4 ± 1.0; week 8: 4.7 ± 0.9) or 6-h TRF (baseline: 8.3 ± 1.2; week 8: 5.5 ± 1.1), versus controls. Percent of participants reporting obstructive sleep apnea symptoms did not change by 4-h TRF (baseline: 44%; week 8: 25%) or 6-h TRF (baseline: 47%; week 8: 20%), versus controls. Conclusion: These findings suggest that 4- and 6-h TRF have no effect on sleep quality, duration, insomnia severity, or the risk of obstructive sleep apnea.

Abstract Background Currently, there is no consistent understanding of the relationship between depression and sleep quality in patients with systemic lupus erythematosus (SLE). This study aimed to explore the correlation between depression and sleep quality in SLE patients. Methods Five English (PubMed, Web of Science, EMBASE, Cochrane Library, and CINAHL) databases were systematically searched from inception to January 12, 2021. Two authors independently screened publications and extracted data according to set inclusion and exclusion criteria. Statistical analyses were performed with STATA 16.0. Data were pooled using a random-effects model. Results A total of 9 identified studies matched the inclusion criteria, reporting on 514 patients with SLE in the analysis. A moderate correlation of depression with sleep quality was found (pooled r = 0.580 [0.473, 0.670]). Compared to good sleepers, patients with SLE and poor sleep quality had higher levels of depression (standardized mean difference =  − 1.28 [− 1.87, − 0.69]). Depression was associated with subjective sleep quality (r = 0.332 [0.009, 0.592]), sleep latency (r = 0.412 [0.101, 0.649]), sleep disturbances (r = 0.405 [0.094, 0.645]), daytime dysfunction (r = 0.503 [0.214, 0.711]), the four dimensions of Pittsburgh Sleep Quality Index (PSQI), while no significant correlation was found in the other three PSQI dimensions. Conclusion Depression had a moderate correlation with sleep quality in patients with SLE. Patients with poor sleep quality tended to have higher level of depression than that of good sleepers. Awareness of the correlation may help rheumatology physicians and nurses to assess and prevent depression and improve sleep quality in patients with SLE.

ABSTRACT Background: Psychiatric problems and sleep disturbances are comorbidities that are frequently encountered among people with epilepsy. However, their presence among the spouses of peoples with epilepsy remains to be elucidated. Objective: The objective of this study was to evaluate the spouses of people with epilepsy (PWE), with and without a history of seizures during sleep, in terms of depression, anxiety and sleep quality. Methods: This prospective, cross-sectional study was conducted in three groups of 18 to 65-year-olds. Group 1 consisted of healthy spouses of 127 healthy volunteers without any known neurological disease; group 2 comprised spouses of 63 PWE who had no history of seizure during sleep; and group 3 consisted of spouses of 63 PWE who had a history of at least one seizure during sleep in the course of the previous year. Questionnaires seeking demographic data and the Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory and Beck Anxiety Inventory were applied to all participants. Results: The depression scores of the group of spouses of PWE were higher than those of the control group and were higher in group 3 than in group 2 (p = 0.017). The anxiety scores of the group of spouses of PWE were significantly higher than those of the control group, but no difference in anxiety scores was found between group 2 and group 3 (p = 0.170). The mean PSQI score of group 3 was higher than that of group 2 (p = 0.029). However, regression analyses did not show any difference between these groups. Conclusion: We found that the PSQI scores, which reflected sleep quality, were higher among the spouses of PWE who had seizures during sleep and who had more severe epilepsy.

Sleep is defined as an easily reversible periodic state marked by the absence of wakefulness. Studies have shown that university students tend to have a diminished amount of sleep. This would lead to the loss of concentration, daytime sleepiness, and reduced academic performances. The aim of this study was to investigate the effects of yoga on overall sleep quality, depression, anxiety, stress, and blood glucose levels. A total of 88 participants with 44 students in each group, control and experimental, were recruited from Universiti Tunku Abdul Rahman based on the outcome of the Godin Shephard questionnaire. A total score of less than 14 was considered mild hence falling into the control group while above 14 and had practiced yoga for a minimum of 6 weeks were placed in the experimental group. The participants were required to self-administer a set of questionnaires consisting of socio-demographic information, the Pittsburgh Sleep Quality Index (PSQI) questionnaire and Depression, Anxiety, Stress Scores. Three components of sleep, namely the habitual sleep efficiency, sleep disturbances, and daytime dysfunctions, were better in the experimental group compared to the control one. Depression, anxiety, stress, and blood glucose levels also appeared to be more desirable in the experimental group with yoga students. It was found that blood glucose levels were positively correlated to the Global PSQI score, depression, anxiety, and stress measures in this study. In conclusion, yoga-practicing students have healthier sleep patterns, negative emotional states, and blood glucose levels. In order to obtain more conclusive findings, similar studies should be carried out in different universities with larger sample size and for longer periods.

Subjective Sleep

Although sleep problems at young ages are well investigated, the prevalence of bad sleepers and the determinants of sleep quality perception remain unexplored in these populations. For this purpose, we addressed these issues in a sample of children (n = 307), preadolescents (n = 717), and adolescents (n = 406) who completed the School Sleep Habits Survey, addressing sleep quality perception, sleep habits, sleep features, daytime behavior and sleep disturbances, circadian preference, and dreaming. The sample was split in “good sleepers” and “bad sleepers”, based on the answer to the question item assessing overall subjective sleep quality. Being a bad sleeper was reported by 11.7% of the sample, with significant between-groups differences (children: 8.3%; preadolescents: 11.3%; adolescents: 15.3%; p = 0.01). At all ages, relative to good sleepers, bad sleepers showed higher eveningness, sleepiness, and depression, longer sleep latency, more frequent insufficient sleep, nocturnal awakenings, sleep–wake behavioral problems, and unpleasant dreams (all p’s ≤ 0.01). Sleep quality perception was predicted: in children, by depressed mood, eveningness, and unpleasant dreams (all p’s ≤ 0.01); in preadolescents, by sleep latency, awakening frequency, depressed mood, sufficiency of sleep, and unpleasant dreams (all p’s < 0.01); in adolescents, by awakening frequency, depressed mood, and sufficiency of sleep (all p’s < 0.001). In children, bad subjective sleep quality appears to be mainly determined by daytime psychological features, for example, depressed mood, whereas at later ages, sleep characteristics, such as frequent awakenings, add to the former determinants. This could depend on (a) the appearance, with increasing age, of objective sleep modifications and (b) a greater attention paid by adolescents to their sleep characteristics.

Objectives Sleep disturbances are frequently observed in rheumatic diseases including systemic lupus erythematosus (SLE). This study aimed at evaluating the prevalence of insomnia, poor sleep quality and their determinants in a cohort of SLE patients. Methods Eighty-one consecutive SLE female patients were evaluated in a cross-sectional study. The Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), the Beck Depression Inventory (BDI) and the Self-rating Anxiety Scale (SAS) were administered. Patients with previous diagnosis of obstructive sleep apnea or restless legs syndrome were excluded. Fifty-three women with hypertension (without SLE) were enrolled as control group (H). Results In the SLE cohort poor sleep quality (65.4% vs 39.6%, p < 0.01) and difficulty in maintaining sleep and/or early morning awakening (65.4% vs 22.6%, p < 0.001), but not insomnia (33.3% vs 22.6%, p = ns), were more prevalent than in H. Depressive symptoms were present in 34.6% of SLE vs 13.2% H patients ( p < 0.001) while state anxiety was more common in H patients (H 35.8% vs SLE 17.3%, p < 0.005). SLE was associated with a 2.5-times higher probability of presenting poor sleep quality in comparison to H (OR 2.5 [CI 1.21–5.16]). After adjusting for confounders, both depressive symptoms (OR 4.4, [1.4–14.3]) and use of immunosuppressive drugs (OR 4.3 [CI 1.3–14.8]) were significantly associated with poor sleep quality in SLE patients. Furthermore, poor sleep quality was not associated either with disease duration or activity. Conclusions In a cohort of SLE women, insomnia and poor sleep quality, especially difficulties in maintaining sleep, were common. Depressive symptoms might be responsible for the higher prevalence of poor sleep quality in SLE.

ABSTRACT Objective: To evaluate and compare subjective sleep quality in medical students across the various phases of the medical course. Methods: This was a cross-sectional study involving medical undergraduates at one medical school in the city of Botucatu, Brazil. All first- to sixth-year students were invited to complete the Pittsburgh Sleep Quality Index, which has been validated for use in Brazil. Participants were divided into three groups according to the phase of the medical course: group A (first- and second-years); group B (third- and fourth-years); and group C (fifth- and sixth-years). The results obtained for the instrument components were analyzed for the total sample and for the groups. Results: Of the 540 students invited to participate, 372 completed the instrument fully. Of those, 147 (39.5%) reported their sleep quality to be either very or fairly bad; 110 (29.5%) reported taking more than 30 min to fall asleep; 253 (68.0%) reported sleeping 6-7 h per night; 327 (87.9%) reported adequate sleep efficiency; 315 (84.6%) reported no sleep disturbances; 32 (8.6%) reported using sleeping medication; and 137 (36.9%) reported difficulty staying awake during the day at least once a week. Group comparison revealed that students in group A had worse subjective sleep quality and greater daytime dysfunction than did those in groups B and C. Conclusions: Medical students seem to be more exposed to sleep disturbance than other university students, and first- and second-years are more affected than those in other class years because they have worse subjective sleep quality. Active interventions should be implemented to improve sleep hygiene in medical students.

AbstractThe aims of this study were (i) to compare the chronotype distribution of elite athletes to a young adult population and (ii) to determine if there was a tendency for athletes to select and/or participate in sports which suited their chronotype. A total of 114 elite athletes from five sports (cricket, cycling, hockey, soccer and triathlon) participated in this study. The participants’ chronotype, sleepiness, sleep satisfaction and sleep quality were determined using the Horne and Östberg Morningness and Eveningness questionnaire, the Epworth Sleepiness Scale and questions concerning their sleep satisfaction and quality. All questionnaires were administered during a typical training phase that was not in the lead up to competition and/or post competition. No differences between chronotype group for sleepiness, sleep satisfaction or sleep quality were found. There was a significantly higher proportion of triathletes that were morning and intermediate types compared to the control group χ2 (2) = 7.5, p = 0.02. A significant relationship between sport and chronotype group (χ2(4)=15.9, p = 0.04) was observed, with a higher frequency of morning types involved in sports that required morning training. There was a clear indication that athletes tended to select and pursue sports that suited their chronotype. This was evident by the amount of morning types involved in morning sports. Given that athletes are more likely to pursue and excel in sports which suit their chronotype, it is recommended that coaches consider the athlete’s chronotype during selection processes or if possible design and implement changes to training schedules to either suit the athletes’ chronotype or the timing of an upcoming competition.
