[Measurement of the perceived impact of sleep problems: the Spanish version of the functional outcomes sleep questionnaire and the Epworth sleepiness scale].

BACKGROUND: Excessive daytime sleepiness is a frequent symptom and a public health problem due to its association with automobile and work related accidents. The aim of this study was to develop and carry out a preliminary assessment of the Spanish version of the functional outcomes sleep questionnaire and the Epworth sleepiness scale, two instruments designed to evaluate patients with sleep disorders. MATERIAL AND METHODS: For the adaptation, the forward and back-translation method by bilinguals was used with professional and lay panel. Once tested for feasibility and comprehension, 39 patients with obstructive sleep apnea syndrome completed the Spanish version of the FOSQ and the Epworth sleepiness scale, together with a question on self-rated health status. RESULTS: Difficulty of translation was assessed as low and the naturalness of Spanish expressions as high for all the items of the questionnaires except for the response options of the Epworth sleepiness scale. Both questionnaires showed higher reliability than the standard proposed for individual comparisons (Cronbach's alpha > 0.9). The FOSQ vigilance scale showed a high correlation with the Epworth score (r = -0.79), while for the other scales of the FOSQ correlations were moderate (r ranging from -0.52 to -0.68). Patients who reported "regular" or "poor" health had significantly worse scores for most of the FOSQ scales. CONCLUSION: These results suggest that the Spanish versions of both questionnaires are conceptually equivalent to the originals and that they show similar characteristics of reliability and validity. The FOSQ vigilance scale assess daytime sleepiness similarly to Epworth but the others scales of the FOSQ provide additional information for these patients.

Prevalence of sleep problems and their association with inattention/hyperactivity among children aged 6-15 in Taiwan.

This study investigated the 6-month prevalence rates of sleep-related problems and their association with daytime inadvertent napping, inattention, hyperactivity/impulsivity, and oppositional symptoms in children and adolescents. A representative school-based sample of 2463 first to ninth graders was recruited using a multistage sampling method. The instruments included the Sleep Habits Questionnaire (including dyssomnia, parasomnia, sleep schedules, and sleep-disordered breathing), the Chinese Health Questionnaire, and the Chinese versions of the Conners' Parent and Teacher Rating Scales-Revised: Short forms. The informants were mothers and teachers. The linear and nonlinear mixed models were used for statistical analyses and sex and age were controlled in the model. Results showed that the rates of middle insomnia, disturbed circadian rhythm, mouth breathing, and daytime inadvertent napping increased with age; whereas those of bedwetting, bruxism, sleep terrors decreased with age. Dyssomnia, sleep-disordered breathing problems, daytime inadvertent napping, and sleep schedules were related to attention-deficit/hyperactivity disorder (ADHD)-related symptoms as assessed by mothers' and teachers' ratings. Parasomnia was associated with ADHD-related symptoms as assessed by mothers' ratings. Our findings suggest an age trend of sleep problems similar to those found in the literature and the association of daytime inadvertent napping, inattention, hyperactivity/impulsivity, and oppositional symptoms with sleep-related problems.

[Combined use of zolpidem and enalapril in elderly patients with essential arterial hypertension and sleep problems].

Changes in 24-h profiles of arterial pressure following treatment with zolpidem were studied in 12 patients with essential arterial hypertension and chronic sleep problems on enalapril. One week treatment with zolpidem improved quality of sleep, increased a circadian index of systolic arterial pressure, 3 non-dipper patients recovered circadian rhythm of arterial pressure. The antihypertensive effect at night was higher when enalapril was used in combination with zolpidem than in monotherapy with enalapril.

Subjective sleep problems in later life as predictors of cognitive decline. Report from the Maastricht Ageing Study (MAAS).

BACKGROUND: Although biological sleep criteria seem to be associated with cognitive changes in older people, it is not clear if subjective sleep parameters are related to cognitive decline in later life. OBJECTIVES: The aim of this study was to determine whether subjective sleep complaints in a population-based sample of 838 middle aged and older adults (>or= 50 years) predicted cognitive decline over a period of 3 years. METHODS: Sleep complaints at baseline, assessed with the subscale Sleep Problems of the Symptoms Checklist-90, were used as a predictor variable. Cognitive performance at follow-up, measured with the Mini Mental Status Examination, was employed as a dependent variable. RESULTS: Controlling for the effects of age, gender, length of follow-up interval, systemic diseases, and cognitive function at baseline, subjective sleep complaints were negatively associated with cognitive performance at follow-up. CONCLUSION: Subjective sleep complaints predict cognitive decline in middle aged and older adults. Mechanisms behind the effect of subjective sleep complaints on cognitive performance are discussed.

Sleep problems in toddlers: effects of treatment on their daytime behavior.

OBJECTIVE: This study investigated the effects of a treatment program for severely sleep-disturbed children on their daytime interaction with their mothers. METHOD: Twenty-eight children with serious sleep problems and 30 matched controls, aged 12 to 36 months, were compared on behavior rating scales, on sleep patterns, and during play and feeding interactions with their mothers before and after an intervention program. RESULTS: After treatment the sleep-disturbed children improved in their behavior, in their sleep patterns, and during feeding interactions with their mothers. However, the behavior of the children but not that of their mothers improved. CONCLUSIONS: The findings of this study indicate that a brief behavioral intervention program focused on helping families manage children with sleep disturbances can generalize to daytime mother-child interactions. This suggests that a compromised relationship in early life may be modified by rather simple interventions since changes of one behavioral system may modify the total relationship of young children with those caring for them.

Neuropsychological and psychosocial function in children with a history of snoring or behavioral sleep problems.

OBJECTIVES: To compare neuropsychological and psychosocial function in children with a history of snoring, children with a history of behavioral sleep problems (BSP), children with both a history of snoring and BSP, and a group of control subjects. STUDY DESIGN: Families awaiting consultation for "sick" visits in 5 general practice clinics completed the Sleep Disturbance Scale for Children. A subset of children were categorized into groups: Snorers (n = 11), BSP (n = 13), Snorers+BSP (n = 9), and controls (n = 31). Children underwent psychological (Wechsler Abbreviated Scale of Intelligence, Children's Memory Scale; Test of Everyday Attention and Auditory Continuous Performance Test) and psychosocial assessment (Child Behavior Checklist). RESULTS: With analysis of variance, it was revealed that, compared with children in the BSP and control groups, those in the Snorers+BSP and Snorers groups showed reduced intelligence and attention scores. By contrast, compared with children in the Snorers and control groups, children in the Snorers+BSP and BSP groups reported reduced social competency, increased problematic behavior, and reduced memory scores. Children in the combination of Snorers+BSP group showed more deficits than children in all other groups. CONCLUSION: In children, snoring and BSP, separately and together, are associated with impaired neuropsychological and psychosocial functioning. Furthermore, snoring and BSP are related to performance in disparate ways. Snoring was associated with intelligence and attention deficits, whereas BSP was associated with memory and behavioral deficits.

Treatment of sleep problems in families with small children: is written information enough?

UNLABELLED: The aim of this study was to evaluate a standardized sleep programme, i.e. a two-step variation of graduated extinction, where the child is first taught to fall asleep by him/herself at bedtime (first intervention) and 2 wk later also after night wakings (second intervention). The outcome after consultations with a therapist followed by telephone support during both interventions was compared with the outcome after giving written information only during the first intervention and therapist support during the second. A total of 67 families with infants exhibiting spontaneous awakening and crying episodes during the night were randomly assigned to either programme. There were no significant differences in terms of outcome between the two groups. In both groups the number of registered night wakings decreased immediately following the first intervention. At registration, at 1 mo and 3 mo later, all parents, with the exception of one couple at the 3-mo follow-up, reported that the sleep problem had improved. CONCLUSION: If parents experience their infant's night awakenings as a problem, teaching their infant to fall asleep by him/herself usually solves this problem quickly. Written information is in most cases sufficient to help parents introduce the new evening routines.

The use of clonidine for severe and intractable sleep problems in children with neurodevelopmental disorders--a case series.

This paper reports on the use of clonidine for the treatment of severe sleep problems associated with behavioural difficulties in children with neurodevelopmental disabilities. Data were obtained from reviewing the case notes of a series of six children with neurodevelopmental disorders of different nature and severity, presenting with problematic sleep. All children in this group showed maintained improvements in their sleep pattern following the use of clonidine with only mild side-effects reported.

[The influence of lifestyle and night-shift work on sleep problems among female hospital nurses in Japan].

STUDY OBJECTIVE: In this study, by conducting a questionnaire survey, we aimed to clarify the situation regarding sleep disorders in female hospital nurses and their relation with night-shift work and lifestyle. METHODS: The subjects were female nurses working at 5 hospitals, each with more than 400 beds. The survey was carried out in July 2000. The questionnaire contained six items concerning sleep quality from the Pittsburgh Sleep Quality Index (PSQI), two new items on sleep drafted by ourselves, and some questions on lifestyle and shift-work status. RESULTS: Among all female nurses, statistically significant differences were observed between those working and those not working night shifts for 7 items regarding sleep (P < 0.05). Significant correlations were observed between sleep disorders and the following factors: (1) working night shift, (2) having anxiety or stress, (3) getting less than 6 hours of sleep, (4) working in cities, (5) having children, and (6) bathing more than 1 hour before going to bed. In addition, significant correlations were observed between getting less than 6 hours of sleep and the following factors: (1) being 40 years of age or older, (2) working in cities, and (3) having anxiety or stress. CONCLUSIONS: The results of this study suggest that sleep problems among nurses are associated not only with night-shift work but also with lifestyle. They also suggest that nurses who work night shifts, especially in Tokyo, should try to get sufficient hours of sleep to ensure good quality of sleep.

Associations of sleep problems and recent life events with smoking behaviors among female staff nurses in Japanese hospitals.

For the purpose of examining the relation of sleep problems and other possible correlates with smoking among staff nurses in hospitals, the cross-sectional data of a self-administered questionnaire survey for 522 Japanese female staff nurses were reanalyzed. Registered nurses or licensed practical nurses were 82%, while nursing assistants were 18%. The prevalence of current smoking (PCS) was 29%, being higher than that in the general population of Japanese women. The current smokers exhibited a high tendency toward tobacco dependence. Multivariate analyses revealed that PCS was associated with recent frequent night shifts and a large amount of support from coworkers, while the association of a large amount of job control and a feeling of light overnight sleep with PCS was also suggested. The tobacco-dependent tendency was associated with recent life events and the presence of insomnia. It is possible that smoking is a countermeasure against sleepiness caused by the disadaptation to shift-work, or that tobacco-intake pharmacologically disturbs sleep. For decreasing PCS in staff nurses, further research should focus on the relation of smoking with their sleepiness and shift-working system, and also on the process in which major life events develop smoking behaviors.

Behaviour modification in the treatment of sleep problems occurring in young children: a controlled trial using health visitors as therapists.

A controlled trial of behaviour modification in the treatment of sleep problems is described. The subjects were 51 children aged 4 months to 4 1/2 years (mean 20 months) recruited from the community by health visitors (specialist nurses based in the community). In the experimental procedure health visitors were trained and supported in the use of behaviour modification. At 6 months follow-up both control and experimental groups showed equally marked improvement. Reasons for the failure to demonstrate an effect are discussed.

A longitudinal study of bed sharing and sleep problems among Swiss children in the first 10 years of life.

OBJECTIVE: To study age trends, long-term course and secular changes of bed-sharing practices, and sleep problems among Swiss families. METHODS: A total of 493 children were longitudinally followed between 1974 and 2001 by using structured sleep-related interviews at 1, 3, 6, 9, 12, 18, and 24 months after birth and at annual intervals thereafter until 10 years of age. Parents were queried about bed sharing, night wakings, bedtime resistance, and sleep-onset difficulties during the 3 months before each follow-up interview. RESULTS: Although in the first year of life relatively few children slept with their parents (<10%), bed sharing increased with age and reached a maximum at 4 years (> or =1 times per week: 38%). Bed sharing of at least once per week was noted in 44% of the children between 2 and 7 years old. Nocturnal wakings also increased from 6 months old to a maximum at 4 years, when more than half of all children woke up at least once per week (22% every night at 3 years). Less than 10% of all children demonstrated frequent bedtime resistance and sleep-onset difficulties. Bed sharing and night wakings during early infancy were not predictive for bed sharing or night wakings during childhood, whereas both bed sharing and night wakings during childhood tended to persist over time. In contrast, bedtime resistance and sleep-onset difficulties seemed to be rather transient phenomena across all ages. No consistent cohort trends were found except for bedtime resistance, which decreased significantly between 1974 and 2001. CONCLUSIONS: Bed sharing and nocturnal wakings are common during early childhood. Developmental changes in separation-attachment processes, cognitive capabilities to develop self-recognition and nighttime fears, and motor locomotion may contribute to the particular age trend of night wakings and bed sharing during early childhood.

Preventing sleeping problems in infants who are at risk of developing them.

AIMS: (1) To identify factors at 1 week of age which put infants at risk of failing to sleep through the night at 12 weeks of age. (2) To assess whether a behavioural programme increases the likelihood that these infants will sleep through the night at 12 weeks of age. METHODS: A community sample of 316 newborn infants was employed to identify the risk factors at 1 week of age which increased the likelihood of failing to sleep through the night at 12 weeks of age. Infants who met these risk criteria and were randomly assigned to a behavioural programme were compared with at risk infants in the control group on measures of sleeping, crying, and feeding at 12 weeks of age. RESULTS: Infants who had a high number (>11) of feeds in 24 hours at 1 week were 2.7 times (95% CI 1.5 to 4.8) more likely than other control group infants to fail to sleep through the night at 12 weeks of age. At 12 weeks, 82% of these at risk infants assigned to the behavioural programme, compared to 61% in the control group, slept through the night. The findings were similar in breast and bottle feeders. CONCLUSIONS: Preventing infant sleeping problems should be more cost effective than treating them after they have arisen. This study provides evidence that it is possible to identify infants who are at risk of failing to sleep through the night at an early age, and that a simple, three step, preventive behavioural programme increases the number who sleep through the night by 21%.

Perceived anxiety, depression, and sleeping problems in relation to psychotropic drug use among elderly in assisted-living facilities.

OBJECTIVE: The aim of the present study was to investigate the perceived anxiety, depression, sleeping habits, and participation in social activities in relation to psychotropic drug use among elderly in assisted-living facilities and to identify factors of importance for the use of these drugs. METHOD: The study had a cross-sectional design and included 93 residents living in old-age homes or in nursing homes in a municipality in southern Sweden. Data regarding medication was obtained from medical records and included all psychoactive drugs. The perceived anxiety, depression and sleeping habits of the residents were assessed using a structured interview questionnaire. RESULTS: Many of the residents had sleeping problems and also reported problems concerning anxiety and depression. Of the study population, 65 (70%) used one or more psychoactive drug; 9 were prescribed neuroleptics (10%), 29 anxiolytics (31%), 43 hypnotics (43%) and 31 were prescribed anti-depressants (33%). The most commonly used psychotropic drugs as it related to the residents' problems were: benzodiazepines (oxazepam) against anxiety, benzodiazepine-related agents (zoldipem and zopiclon) against insomnia and serotonin reuptake inhibitors (SSRI; citalopram) against depression. The residents who had been treated with psychotropic drugs at home continued this treatment after moving to assisted-living facilities and approximately 30% of the residents were prescribed new psychotropic drugs. Of those that perceived anxiety, insomnia or felt depressed, between 58% and 69%, respectively, had spoken to neither a nurse nor a physician about these problems. Of those that had talked to a nurse/physician about these problems, a majority had been prescribed psychotropic drugs. Factors of importance for treatment with psychotropic drugs against anxiety, insomnia and depression were: prior treatment with these drugs at home and discussing their problems with a physician. CONCLUSION: The communication between the residents and the nurses/physicians appears to be insufficient as the residents state that they have not discussed their problems with a nurse or a physician and that the prescription of psychotropic drugs does not seem to be in proportion to the residents' perceived problems.

Management of infant sleep problems in a residential unit.

Torrens House provides a short residential programme for families with a baby (8-12 months of age) identified by parents as having a sleep problem such as waking frequently at night and being difficult to settle. The programme involves the promotion of infant self-settling by the use of a controlled crying technique, together with wrapping, cessation of night feeds and establishment of a day-time routine. Twenty families (with 23 babies) were followed through the programme and for 3 months afterwards. There were significant decreases in the number of times the babies woke, the number of night-feeds and the length of time awake at night at 1 month follow-up, with a reduction in depressive symptomatology of the parents and a perceived improvement in their infants' behaviour. Twenty of the 23 babies were sleeping well at 3 month follow-up.

A faded bedtime with response cost protocol for treatment of multiple sleep problems in children.

The sleep-wake cycles of 4 developmentally delayed individuals with longstanding severe sleep disturbances were regulated using a faded bedtime procedure with response cost. Bedtimes were systematically delayed for each individual, thus increasing the probability of short latency to sleep onset. The response cost component, consisting of removing the individual from bed for 1 hour, was implemented when an individual did not experience short latency to sleep onset. A fading procedure was then applied successfully to advance the bedtimes and to gradually increase durations of sleep. Specifically, all 4 individuals had decreased amounts of nighttime sleep that increased following treatment. Two of the 4 individuals showed excessive daytime sleep that decreased following treatment. Three of the 4 individuals experienced decreases in night wakings following treatment. Both environmental and biological manipulations of the sleep-wake cycle are hypothesized as mechanisms of treatment. The relative advantages of this procedure over other procedures for the treatment of pediatric sleep disorders are discussed, as are directions for future research.

Sleep disorders in older adults. A primary care guide to assessing 4 common sleep problems in geriatric patients.

Complaints about sleep are common among older adults, yet are not a normal consequence of old age. Disordered sleep can be due to medical conditions, chronic diseases, psychiatric disorders, and medications. Age-associated, oropharyngeal anatomical changes can result in sleep-disordered breathing (sleep apnea). In addition, the circadian rhythm advances that accompany aging can cause early evening lethargy and early morning awakenings. Discovering and treating the underlying cause(s) of the sleep disorder is the first step in approaching the problem.
