“…A strength of this study is the use of actigraphy to provide a more objective estimate of sleep/wake patterns. Despite the known limitations of actigraphy, 36 the current results are more likely to accurately reflect true sleep patterns.…”

Study Objectives:To compare sleep/wake patterns in children born preterm in Australia vs Canada and determine cultural differences in the relationship between parental perception of sleep and actual sleep behaviors. Methods: Australian and Canadian children born preterm were recruited from the Caffeine for Apnea of Prematurity trial (n = 188, 5-12 y) and underwent 14 days actigraphy monitoring. Parents completed the National Sleep Foundation 2004 Sleep in America questionnaire. Cross-cultural differences in sleep characteristics assessed by actigraphy and parent-reported questionnaire were examined. Correlational analyses determined the associations between parental perceptions of child sleep need and sleep behavior. Results: Actigraphy showed preterm children obtained, on average, 8 h sleep/night, one hour less than population recommendations for their age. There was no difference in total sleep time (TST) between Australian and Canadian cohorts; however, bed and wake times were earlier in Australian children. Bedtimes and TST varied by 60 minutes from night to night in both cohorts. Parent-reported child TST on the National Sleep Foundation questionnaire was 90 minutes longer than recorded by actigraphy. Both bedtime and TST on weekdays and weekends were related to parental perception of child sleep need in the Australian cohort. Only TST on weekdays was related to parental perception of child sleep need in the Canadian cohort. Conclusions: This study suggests that short sleep duration and irregular sleep schedules are common in children born preterm. Cultural differences in the association between parental perception of child sleep need and actual sleep behaviors provide important targets for future sleep health education.

“…The different sleeping environments and the attachment of numerous leads and equipment to the patient in the PSG setting could also cause irritation of the skin or other discomfort for the patient with AD, and thus their home sleeping conditions might not be truly reflected. In contrast, actigraphy, a small, wrist-worn device that estimates sleep-wake patterns by using activity-based monitoring, has increasingly been used in recent years for delineating sleep patterns 26,27 because of its ease of use, especially for the pediatric population, 25,28,29 but its validation with PSG measurements in children with AD had not been established. Our study is the first to demonstrate a good correlation of results by actigraphy and PSG in this patient group, and we suggest that actigraphy is a good alternative for further sleep studies in children with AD.…”

Atopic Dermatitis, Melatonin, and Sleep Disturbance

WHAT'S KNOWN ON THIS SUBJECT: Sleep disturbance affects 47% to 60% of children with atopic dermatitis and is a leading cause of impaired quality of life for the patients and their family. WHAT THIS STUDY ADDS:Sleep disturbance in children with atopic dermatitis can be predicted by a Scoring Atopic Dermatitis index of $48.7, and lower nocturnal melatonin secretion might play a role in the pathophysiology. abstract BACKGROUND AND OBJECTIVES: Sleep disturbance is common in patients with atopic dermatitis (AD). However, studies have largely been questionnaire-based, and the pathophysiology remains unclear. The aims of this study were to determine objective characteristics of sleep disturbance in children with AD and explore contributing factors and clinical predictors.METHODS: Sleep parameters were measured by actigraphy and polysomnography in 72 patients with AD and 32 controls ages 1 to 18 years. Urinary 6-sulfatoxymelatonin levels, serum cytokines, and total and allergen-specific immunoglobulin E (IgE) levels were also measured. RESULTS:The patients with AD had significantly reduced sleep efficiency, longer sleep onset latency, more sleep fragmentation, and less nonrapid eye movement sleep. Results from actigraphy correlated well with those from polysomnography. The AD disease severity was associated with sleep disturbance (r = 0.5520.7), and a Scoring Atopic Dermatitis index of $48.7 predicted poor sleep efficiency with a sensitivity of 83.3% and a specificity of 75% (area under the curve = 0.81, P = .001). Lower nocturnal melatonin secretion was significantly associated with sleep disturbance in the patients with AD. Other correlates of sleep disturbance included pruritus, scratching movements, higher total serum IgE levels, and allergic sensitization to dust mite and staphylococcal enterotoxins. CONCLUSIONS:Poor sleep efficiency is common in children with AD and can be predicted by the Scoring Atopic Dermatitis index. Melatonin and IgE might play a role in the sleep disturbance. Further studies are required to explore the mechanisms and clinical implications, and actigraphy could serve as a useful evaluating tool. Atopic dermatitis (AD) is a common chronically relapsing pruritic inflammatory skin disease. 1 Disturbed sleep is frequently reported by the patients and their family and is a major factor leading to an impaired quality of life. [2][3][4] Sleep disturbance can have many negative consequences, including impaired neurocognitive function, higher rates of behavioral problems, and changes in mood. 5,6 Therefore, the recognition and proper management of sleep disturbance should be an important issue in AD.The sleep disturbance in AD might be due to the pruritus and scratching movements during sleep, 7-10 but it is likely that other factors are involved. 11 Melatonin is a hormone secreted by the pineal gland that is essential for regulating the circadian rhythm. 12 Dysfunction in the diurnal secretion of melatonin in patients with AD has been reported, 13 but its association with their sleep disturbance has...

“…Due to the restless nature of children's sleep, however, the variables are not as reliable in the pediatric field as in adult studies 6,7 ; however, the accuracy can be enhanced by using an appropriate algorithm. 8 The GeneActiv actigraph has been proven to be reliable in examining sleep in adults 9 and its validity for studying movement in children has also been documented.…”
