The relationship between sleeping problems and aggression, anger, and impulsivity in a population of juvenile and young offenders.

PURPOSE: The current study examines both the quantity and quality of sleep reported by male adolescents detained in prison, with a focus on exploring the association between the quantity and quality of sleep with aggression, impulsivity, or anger. This represents a novel area of study not yet explored among incarcerated male adolescents. METHOD: One hundred eighty-four offenders took part; 104 young (average age 19 years) and 80 juvenile (average age 16 years). All completed a questionnaire exploring sleeping problems, and measures assessing aggression, anger, and impulsivity. RESULTS: Aggression was found to relate both to the quantity and quality of sleep reported, with reduced quantity and quality predicted by increased overall aggression. Across aggression subscales, only increased hostility was predictive of reduced current hours of sleep and increased problems in sleep quality. Apnea risk scores were not predicted by aggression, anger, or impulsivity. Differences in sleep behavior before and during prison were demonstrated, with evidence for increased poor sleeping habits within detention. No differences were observed between young and juvenile offenders. CONCLUSIONS: This study suggests a potential relationship between aggression and sleep among an incarcerated adolescent male sample, highlighting in particular a role for hostility. The findings are discussed in relationship to implications for treatment and directions for future research.

Symptoms of anxiety and depression in Estonian medical students with sleep problems.

High emotional stress in medical students has been observed in many studies. Our aim in this article was to assess the prevalence of symptoms of anxiety and depression among Estonian medical students and to find relationships between sleep complaints and emotional symptoms. The study group consisted of 413 medical students, ages 19-33 years, at the University of Tartu. Each was asked to complete two questionnaires: the Emotional State Questionnaire (EST-Q), containing 28 questions, and the Questionnaire on Sleep and Daytime Habits, with 25 questions. The anxiety and depression subscales from the EST-Q were applied. From the study group, 21.9% students had symptoms of anxiety, and 30.6% had symptoms of depression. The frequency of anxiety and depressive symptoms was higher in females. In regression and multiple regression analysis, we determined which sleep problems were related to emotional symptoms. The associations were different for men and women. In women, anxiety remained significantly related to waking up because of nightmares and feeling tired in the morning; depressive symptoms were related to difficulties in getting to sleep at night, waking up because of nightmares and nocturnal eating habits, daytime sleepiness, and sleepiness during school lessons. In men, significant relations were clear only for depression: difficulties in falling asleep at night before an exam and subjective sleep quality. The study demonstrated that a high percentage of medical students had emotional symptoms. We found that some sleep problems indicated underlying symptoms of anxiety and depression.

Review of strategies for treating sleep problems in persons with severe or profound mental retardation or multiple handicaps.

During the last 15 years, researchers have shown that a large percentage of persons with severe or profound mental retardation or multiple handicaps have serious sleep problems. These problems can cause emotional and physical burdens for caretakers, interfere with the persons' daily learning and occupational performance, and/or exacerbate deviant behaviors. Several studies have been conducted to assess behavioral and pharmacological strategies (e.g., bedtime fading and response cost, extinction, chronotherapy, and the use of melatonin) for reducing sleep problems. Those studies are reviewed here and the effectiveness, suitability, practicality, and acceptability of the strategies are discussed. Relevant issues for future research are also examined.

Bed sharing, sleep habits, and sleep problems among Chinese school-aged children.

STUDY OBJECTIVES: This study examined the association between bed sharing, sleep habits, and sleep problems among Chinese school-aged children. DESIGN AND SETTING: A questionnaire survey of school-aged children was undertaken in Jinan city, People's Republic of China, in 2001. PARTICIPANTS: A total of 517 elementary-school children (mean age, 10.5 years; 47.4% boys) participated in the survey. MEASUREMENTS: The parents completed the Chinese version of the Children's Sleep Habits Questionnaire and a number of questions that asked about bed sharing and characteristics of the family and child. RESULTS: The prevalence of regular bed sharing in Chinese school-aged children was as high as 18.2%. The rate of bed sharing did not differ between boys and girls but significantly decreased with age from 55.8% in 7-year-olds to 7.2% in 11- to 13-year-olds. Multivariate logistic regression analysis showed that younger age, poor physical health of the child, and crowded housing were associated with an increased likelihood for the child's bed sharing with parents. Bedtime and total sleep duration did not significantly differ between children who shared beds and those who slept alone. Children who shared beds with their parents were reported to have more sleep anxiety and daytime sleepiness than children who slept alone. Bed sharing was not associated with parasomnias and breathing problems during sleep. CONCLUSIONS: Regular bed sharing in Chinese school-aged children was very common and significantly decreased with age. Crowded housing and poor physical health of the child increased the likelihood for children and parents to share beds. Bed sharing may exert influences on sleep quality rather than sleep quantity.

Elementary students' sleep habits and teacher observations of sleep-related problems.

Sleep affects the health and well-being of children and plays a key role in preventing disease and injury, stability of mood, and ability to learn. Unfortunately, children often do not get adequate sleep on a regular basis. This study surveyed 199 fifth-grade students regarding their sleep habits using the Sleep Self-Report (SSR) instrument (child's form), the Morningness/Eveningness (M/E) Scale, and additional demographic questions. Students' teachers also were asked to evaluate their students' behavior using the Teacher's Daytime Sleepiness Questionnaire (TDSQ). Results indicated many students experienced problems with sleep-related behavior. However, correlating the TDSQ scale with the SSR Daytime Sleepiness Subscale produced a weak correlation coefficient, indicating teachers may not be able to accurately identify students with sleep problems. Overall findings indicated these students displayed sleep behavior similar to other US children. However, research involving children's sleep behavior is limited, and more research is needed. Parents should monitor their children's sleep times, and teachers need to be aware how sleep deprivation can affect children's mood, reaction time, and concentration. Health education curricula need to include sleep-related instruction at all grade levels to address this concern.

The prevention of sleep problems and colic.

The pediatrician can prevent or improve most sleep problems. Colicky babies need holding and cuddling. All babies should be placed in their cribs when sleepy but awake. Trained night feeding can be prevented by stretching out the daytime feeding intervals and making middle-of-the-night feedings "brief and boring." Trained night crying can be prevented by not providing any entertainment or lifting the infant out of the crib during the night. Fearful night crying can be prevented by eliminating the source of fears when possible and providing extra holding and reassurance during the day for fears.

Children's sleep: problems and solutions.

It is now believed that up to 43% of children can experience a sleep problem at some stage during their development. Reduced quality of sleep can have important implications for the developing child as it can impair growth, learning and emotional development. It is important for health professionals to understand the significance of sleep and the ways to alleviate problems so that these can be tackled at an early age. By educating people in how to get a good night's sleep we shall hopefully move towards a more happy, healthy and capable child population.

Specific eating and sleeping problems in Prader-Willi and Williams-Beuren syndrome.

Eating and sleeping problems have a high prevalence in mental retardation in general, but are also discussed as characteristic in some genetically determined disorders. A comparative analysis of eating and sleeping behaviours in 28 Prader-Willi- and 32 Williams-Beuren syndrome children by psychometric instruments confirms excessive food-seeking behaviours in PWS and selective food refusal in WBS as specific problems. In both syndromes, however, there is considerable individual variability in these symptoms.

Sleep problems and self-care in very old rural women: nursing implications.

Sleep problems are prevalent among very old rural women. In a effort to manage them, they may resort to the indiscriminate use of OTC medications and alcohol. As part of the comprehensive nursing care needed to address these issues, rural nurses should carefully assess their clients sleep patterns and self-care activities and encourage the use of nonpharmacologic interventions to improve sleep. A knowledge of rural values is essential to this process.

Behavioural treatment to reduce sleep problems in children with autism or fragile X syndrome.

There are few well-controlled, published evaluations of sleep interventions for children with developmental disabilities. This paper evaluates a parent training programme using behavioural principles to reduce sleep problems in children with autism or fragile X syndrome (FXS). Training included bedtime routines, reinforcement, effective instructions, partner support, and extinction (removing reinforcement to reduce a behaviour). Programme efficacy was demonstrated by using a multiple baseline across-participant design. Social validity was also assessed. Five children with autism and one with Asperger syndrome (four males, two females; mean age 5y 6mo; age range 3y 5mo to 7y 4mo) and their parents; and seven children with FXS (six males, one female; mean age 4y 9mo; age range ly 11mo to 9y 1mo) and their parents participated. Ten families completed intervention within the multiple baseline design. Most parents' goals were achieved and visual analysis of the sleep data indicated improvement. Settling problems, night waking, and co-sleeping were effectively reduced. The programme had high social validity and outcomes were clinically significant and maintained at follow-up.

A controlled study of Tourette syndrome. VI. Early development, sleep problems, allergies, and handedness.

Developmental milestones, problems with bladder and bowel control, sleep disturbances, allergies, and handedness were compared in 247 consecutive Tourette syndrome (TS) patients, 17 patients with attention-deficit disorder (ADD), 15 patients with ADD secondary to TS (ADD 2(0) TS), and 47 random controls. There were no significant differences in age of first talking or walking. By contrast, there were significant differences in problems with bladder and bowel control between TS patients and controls, as measured by age of first toilet training, age of last bed-wetting, frequency of enuresis, and age that bowel control was achieved. Sleep problems were pervasive in TS patients, with a significantly increased frequency of sleepwalking, night terrors, trouble getting to sleep, early awakening, and inability to take afternoon naps as a young child. In all diagnostic categories, including mild (grade 1) TS patients, a total sleep-problem score was significantly greater than that in controls. The sleep disorders and other TS symptoms are consistent with TS as a disorder of disinhibition of the limbic system. Allergies and left-handedness have been evoked as contributing to or being associated with ADD and learning disorders. There were no significant differences in the frequency of allergies or left-handedness in TS patients compared with that in controls. We conclude that when there is a clearly defined genetic cause of ADD and learning disorders, it is not associated with an increased frequency of allergies or left-handedness.

Management of sleep problems in Parkinson's disease.

Patients with Parkinson's disease (PD) frequently complain of sleep problems. These can be due to several factors, and the approach to their management depends on careful consideration of the various possible factors in each case. 1. Older people, in general, require less sleep. After retirement, people may also engage in less physical activity, and this factor is of course even more pronounced in patients with PD because of their illness. 2. Daytime naps, either spontaneous or due to drugs, reduce the need for nocturnal sleep. Explanation of these physiological and circumstantial changes may help those PD patients who manifest these consequences. 3. The existence of a severe progressive disease as well as social isolation have psychologic consequences, such as anxiety and depression, that may manifest as insomnia. Furthermore, depression is part of the disease, frequently antedating the motor manifestations, and may manifest as insomnia. 4. In advanced disease, patients may be immobile and have difficulty in getting up or even turning in bed. This causes great inconvenience, and may impair sleep. Long acting anti-Parkinson drugs such as cabergoline or rotigotine patch may help. 5. In some cases, unpleasant hallucinations may appear which prevent the patient from falling asleep. These may respond to atypical neuroleptics. Clozapine and quetiapine are particularly useful, but require attention to possible adverse effects.

Cosleeping and early childhood sleep problems: effects of ethnicity and socioeconomic status.

This study examined ethnic differences in the relationship between cosleeping and sleep problems in the United States, taking socioeconomic status (SES) into consideration. The sample consisted of 186 urban families with a healthy 6- to- 48-month-old child and was grouped as follows: white lower SES (n = 40), white higher SES (n = 54), black lower SES (n = 43), and black higher SES (n = 47). Regular cosleeping was associated with increased night waking and/or bedtime protests among lower SES white children and higher SES black children. Among families who coslept, white parents were more likely than black parents to consider their child's sleep behavior to be a problem, i.e., stressful, conflictual, or upsetting as well as regularly occurring. One explanation is that differing childrearing attitudes and expectations influenced how parents interpreted their children's sleep behavior.

Changes in infant sleep problems after a family-centered intervention.

PURPOSE: To describe a family-centered intervention for sleep disturbed infants and its effect on the infants' sleep pattern. METHODS: The sample consisted of 33 infants (6-23 month of age) hospitalized because of sleep problems in The City Hospital in Reykjavik, Iceland, and 33 mothers and 30 fathers. Infants' sleep patterns were assessed by a 1-week diary and by interviews with parents before hospital admission, 1 week and 2 months after discharge. The intervention was based on correction of day-sleep rhythm, support of self-comforting capabilities of the infant, and education of parents in regard to the infants' characteristics and developmental status. Changes in day naps and infant irritability over daytime also improved significantly. FINDINGS: Night sleep improved significantly 1 week after discharge and even more so 2 months later. CONCLUSIONS: Offering a family-centered intervention improves infants' sleep patterns up to 2 months after discharge.

The relative efficacy of two brief treatments for sleep problems in young learning disabled (mentally retarded) children: a randomised controlled trial.

BACKGROUND: Settling and night waking problems are particularly prevalent, persistent, and generally considered difficult to treat in children with a learning disability, although intervention trials are few. Scarce resources, however, limit access to proven behavioural treatments. AIMS: To investigate the efficacy of a media based brief behavioural treatment of sleep problems in such children by comparing (1) face-to-face delivered treatment versus control and (2) booklet delivered treatment versus controls. METHODS: The parents of 66 severely learning disabled children aged 2-8 years with settling and/or night waking problems took part in a randomised controlled trial with a wait-list control group. Behavioural treatments were presented either conventionally face-to-face or by means of a 14 page easy to read illustrated booklet. A composite sleep disturbance score was derived from sleep diaries kept by parents. RESULTS: Both forms of treatment were almost equally effective compared with controls. Two thirds of children who were taking over 30 minutes to settle five or more times per week and waking at night for over 30 minutes four or more times per week improved on average to having such settling or night waking problems for only a few minutes or only once or twice per week (H = 34.174, df = 2, p<0.001). These improvements were maintained after six months. CONCLUSIONS: Booklet delivered behavioural treatments for sleep problems were as effective as face-to-face treatment for most children in this population.

Prevalence of sleep problems in Hong Kong primary school children: a community-based telephone survey.

STUDY OBJECTIVES: To estimate the prevalence of snoring, witnessed sleep apnea, teeth grinding, primary and secondary nocturnal enuresis, and sleep duration in Hong Kong primary school children. DESIGN: Cross-sectional telephone questionnaire survey in a community. PARTICIPANTS: A total of 3,047 6- to 12-year-old apparently healthy children. INTERVENTION: Those who agreed to the study were contacted by telephone. Survey questions were asked about the symptoms of the different sleep disorders, and the frequency of each positive symptom was noted for the preceding 1 week. OUTCOME MEASURES: Prevalence and risk factors of sleep disorders in Hong Kong primary school children. RESULTS: The prevalence of the following sleep symptoms was listed as follows: habitual snoring (10.9%), witnessed sleep apnea (1.5%), nocturnal enuresis (5.1%), and sleep teeth grinding (20.5%). Significant risk factors for habitual snoring included witnessed sleep apnea, mouth breathing during sleep, snoring in first-degree relatives, headache on rising, male gender, allergic rhinitis, and sleep teeth grinding. Significant risk factors for witnessed sleep apnea included habitual snoring, allergic rhinitis, tiredness on rising, and excessive daytime sleepiness. Poor academic results were associated with present of witnessed sleep apnea and absence of sleep teeth grinding. None of the sleep problem was associated with poor conduct results. The mean sleep duration was 8.79 h (SD 0.96). CONCLUSIONS: This study provides epidemiologic data of sleep-disordered breathing, enuresis, sleep teeth grinding, and duration of sleep in Chinese primary school children in Hong Kong.

Personality and coping: predictors of depression and sleep problems among caregivers of individuals who have cancer.

This cross-sectional study described personality and coping and examined their relationships with depression and sleep in 51 adult caregivers of individuals who have cancer. Findings are compared with dementia caregiver literature. Fifty-two percent of caregivers reported Center for Epidemiological Studies-Depression (CES-D) scores greater than 16, and 95% reported Pittsburgh Sleep Quality Index (PSQI) scores greater than 5, indicating risk for clinical depression and severe sleep problems. Less functional coping, optimism, mastery, neuroticism, and sleep predicted 66.4% of the variance in depression. Less functional coping, mastery, neuroticism, and depression predicted 41% of the variance in sleep. Neuroticism and mastery predicted 45.3% of the variance in less functional coping strategies. Caregiver optimism and mastery levels were consistent with levels found in dementia studies. Neuroticism scores were higher than in studies of caregivers of individuals with dementia. Mastery and neuroticism were related to depression, as in other caregiver studies. Findings suggest there are far more similarities than differences between caregivers of individuals who have cancer and caregivers of those who have dementia. Caregiver personality and coping strategies appear to be related to caregiver outcomes similarly in the cancer and dementia populations.
