Sleep disorders are extremely common in children and young people, and even more so in those with developmental disabilities. This client subgroup may prove refractory to standard behavioural and other psychosocial interventions that usually help and it is frequent for clinicians to resort to medication approaches given the high levels of personal and family distress that result. There is a need not only for further well structured research in this field but also for efforts to tackle the frequent relative neglect by clinicians of more researched and considered approaches. This review examines these issues selectively, focusing on important clinical issues and predicaments, and attempts a start at an evidence‐based background for practical and rational prescribing in this area of common childhood psychopathology.

Posttraumatic stress disorder (PTSD), an anxiety disorder with lifetime prevalence of 7.8%, is characterized by symptoms that develop following exposure to traumatic life events and that cause an immediate experience of intense fear, helplessness or horror. PTSD is marked by recurrent nightmares typified by the recall of intrusive experiences and by extended disturbance throughout sleep. Individuals with PTSD respond poorly to drug treatments for insomnia. The disadvantages of drug treatment for insomnia underline the importance of non-pharmacological alternatives. Thus, the present study had three aims: first, to compare the efficiency of two relaxation techniques (muscular relaxation and progressive music relaxation) in alleviating insomnia among individuals with PTSD using both objective and subjective measures of sleep quality; second, to examine whether these two techniques have different effects on psychological indicators of PTSD, such as depression and anxiety; and finally, to examine how initial PTSD symptom severity and baseline emotional measures are related to the efficiency of these two relaxation methods. Thirteen PTSD patients with no other major psychiatric or neurological disorders participated in the study. The study comprised one seven-day running-in, no-treatment period, followed by two seven-day experimental periods. The treatments constituted either music relaxation or muscle relaxation techniques at desired bedtime. These treatments were randomly assigned. During each of these three experimental periods, subjects' sleep was continuously monitored with a wrist actigraph (Ambulatory Monitoring, Inc.), and subjects were asked to fill out several questionnaires concerned with a wide spectrum of issues, such as sleep, depression, and anxiety. Analyses revealed a significant increase in objective and subjective sleep efficiency and a significant reduction in depression level following music relaxation. Moreover, following music relaxation, a highly significant negative correlation was found between improvement in objective sleep efficiency and reduction in depression scale. The study‘s findings provide evidence that music relaxation at bedtime can be used as treatment for insomnia among individuals with PTSD.

The purpose of this study is to evaluate the relationship between sleep disturbances, gastrointestinal (GI) problems and eating behaviors in children who are diagnosed with autistic disorder (AD) and pervasive developmental disorder not otherwise specified (PDD-NOS).

This study was conducted with 102 children who were diagnosed with autism spectrum disorder (ASD). Sleeping and GI (abdominal pain, constipation, diarrhea, vomiting, difficulty swallowing) problems in children were obtained by asking their parents using a questionnaire. The feeding assessment survey (FAS), brief autism mealtime behavior inventory (BAMBI) and food consumption frequency were used to obtain information about the children’s eating habits.

The BAMBI total score, food refusal and features of autism subscale scores of those with AD were higher than those in the PDD-NOS group (p < 0.05). Sleeping, GI and eating problems are seen in those with AD more commonly than in those diagnosed with PDD-NOS.

To the knowledge, this is the first study that compares GI, sleeping and eating problems in children with AD and PDD-NOS. Sleeping, GI and eating problems may be more frequent in children with AD than in those with PDD-NOS. The GI problem rate is higher in children with autism with sleeping problems than without sleeping problems.

Firefighting can pose a number of psychological health risks due to the nature of the job. Previous studies have examined the relationship between distress symptoms in firefighters and factors such as age, experience in the service, workload, sleep and alcohol use. However, the relationship between risk factors and mental health problems in firefighters remains unclear. In the present study, the authors aim to assess mental distress among Muscat firefighters using the Brief Symptom Inventory-18. The authors expected that this research will allow researchers to determine the prevalence of mental distress among Muscat firefighters and assess the role of the above risk factors on the ratio.

The assessment includes the prevalence of anxiety, somatization and depression symptoms among firefighters. The impact of sociodemographic factors, sleep problems and smoking on symptomatic cases was also evaluated. Data was collected from 110 firefighters then processed as per instructions in the BSI-18 manual to identify clinical cases in each of the three scales of the assessment.

Results show that all factors influence the number of cases to different extents. Young, single firefighters with high school level education were found to have the highest number of extreme cases followed by those who are non-smokers and satisfied with their job. This study did not find a relationship between sleep disorder and job dissatisfaction with regard to the number of critical cases. The prevalence of anxiety, somatic and depression cases among firefighters was found to be 11.8%, 10.9% and 10%, respectively. These findings have implications for fire service work-organization policies and for the development and monitoring of treatment programs for firefighters.

This work presents a comprehensive assessment on common factors that may impact prevalence of mental distress among an underrepresented firefighter community. These findings have implications for fire service work-organization policies and for updating current monitoring programs or updating new programs for firefighters.

Although ageing itself does not lead to insomnia, changes in sleep architecture (the ‘typical’ physiological progression from wakefulness to deep sleep) and health status create a vulnerability to the development of insomnia, which can be precipitated by a trigger event. This review highlights some of the problems associated with insomnia in older people and offers insights into the possible approaches to stop insomnia from becoming a ‘rite of passage’. The main conclusion from this review however, is that sleep research focusing specifically on the ageing population is badly needed, alongside a unified diagnostic system and research structure (Leger, 2000). These findings are also discussed in relation to both healthcare policy and practice.

This paper aims to investigate if a sensory intervention of moderate pressure touch of children with sensory processing disorder (SPD) affects sleep behaviours and sensory processing behaviours.

A total of 50 children, aged 5–11 years with both SPD and sleep difficulties in Israel, were randomly divided into an experimental and a control group, nonblinded. Participants in the experimental group received three weeks of nightly massage by their parents, with a baseline week on both ends. Parents filled out questionnaires reporting on sensory and sleep behaviours and filled out a nightly sleep log. Parents determined outcome goals using goal attainment scoring. The assessment tools used were the short sensory profile and the child sleep habits questionnaire (Dunn, 1999; Owens et al., 2000).

Significant improvement was found in the total and subgroup scores of sleep participation measures including sleep onset, sleep anxiety, parasomnias, sleep duration, daytime sleepiness, as well as the total sleep score (F (1,48) = 24.71, p < 0.001).

Results of this study suggest that consistent application of moderate pressure touch as advised or trained by an occupational therapist may be used in clinical practice to improve sleep participation in children with SPD.

Sleep arousal detection is an important factor to monitor the sleep disorder.

Thus, a unique nth layer one-dimensional (1D) convolutional neural network-based U-Net model for automatic sleep arousal identification has been proposed.

The proposed method has achieved area under the precision–recall curve performance score of 0.498 and area under the receiver operating characteristics performance score of 0.946.

No other researchers have suggested U-Net-based detection of sleep arousal.

From the experimental results, it has been found that U-Net performs better accuracy as compared to the state-of-the-art methods.

Sleep arousal detection is an important factor to monitor the sleep disorder. Objective of the work is to detect the sleep arousal using different physiological channels of human body.

It will help in improving mental health by monitoring a person's sleep.

Insomnia is highly prevalent in prisoners. The purpose of this paper is a review of research evidence on interventions with sleep as an outcome (2000 to 2020) and rates of insomnia prevalence and associated factors in prisons (2015 to 2020).

An internet-based search used Medline, PubMed, PsycINFO (EBSCOhost), Embase, Web of Science and Scopus. Seven interventions and eight sleep prevalence or sleep-associated factor papers were identified.

Intervention research was very limited and the quality of the research design was generally poor. Interventions such as cognitive behavioural therapy for insomnia (CBT-I), yoga and mindfulness can be beneficial in a prison setting. This review identified a high prevalence of insomnia in prisons across the world, which was supported by recent evidence. Factors associated with insomnia include anxiety, depression, post-traumatic stress disorder, personality disorder and pain.

There is a need for appropriately powered randomised control trials of CBT-I in prisons and a need to use objective measures of sleep quality.

Due to a lack of an up-to-date review, this paper fulfils the need for a review of the evidence on interventions in prison settings with sleep as an outcome, rates of insomnia prevalence and associated factors in prisons.

Sleep disturbances, present in more than 90% of major depressive disorder (MDD) patients, are moderated by sex in adult MDD. In particular, slow-wave electroencephalographic activity (SWA; 0.5-4 Hz) accumulation is low and dissipation impaired. This SWA abnormality in depressed adult males does not change with age, suggesting that SWA abnormality appears at early ages. The present study evaluated sex differences in SWA in adolescents with MDD compared to healthy controls. We evaluated regularized sleep-wake schedules at home for 5-7 days, followed by two consecutive nights of sleep EEG recording. The study included 104 participants, 52 symptomatic and depressed subjects (MDD: 20 males and 32 females) and 52 healthy controls (HC: 20 males and 32 females), aged 13-18 years. SWA power and dissipation, and duration and latencies to each Non-Rapid Eye Movement (NREM) sleep period were calculated for each group. Results showed that SWA accumulation in the first NREM period was lower and its dissipation across the night more irregular in MDD males compared to HC males (P<0.009). By contrast, SWA was equivalent in MDD and HC females. In conclusion, as reported in adult MDD, the accumulation and dissipation of SWA was abnormal in depressed adolescents, but only in males. SWA abnormalities in adolescent MDD may relate to different depressive symptoms in females and males. These results underscore the need to develop sex-specific therapies to enhance and restore SWA in depressed adolescents.

This study aims to look at the prevalence of obesity and its association with sleep problems among police officers.

The authors conducted a cross‐sectional study of the relationship between obesity and sleep disorders among 110 randomly selected police officers from the Buffalo, New York, Police Department in 1999. Participants, who ranged in age from 26 to 61 years (mean±SD=39.5±7.5), responded to sleep related questions and had anthropometric measurements taken.

Results show that several measures of obesity were significantly associated with sleep‐disordered breathing in police officers, but not with other sleep problems.

A major strength of the study was that it was conducted in a cooperative and motivated study population. It was possible to assess a wide range of anthropometric measurements, including many that are important but are rarely used to measure obesity in epidemiologic studies such as abdominal height, neck circumference, and neck‐to‐height ratio. In addition, the assessment of the anthropometric indices was performed by trained clinic staff using standardized procedures.
