“…Parental overestimation of sleep duration reflected the occurrence of unnoticed night-wakings and consistent reports of earlier bedtimes and later wake-up times compared with actigraphy (20,23). Actigraphy results on WASO were significantly higher than parental reports, which is in line with other studies (26,27,33,52), even for children in their 1st year (29). This discrepancy may be due either to a tendency for actigraphy to mistakenly overestimate night-wakings when the child's sleep is restless (9) or to a parental inability to report them, as the child's growing self-regulation tools allow him to resume sleep without requesting parental intervention.…”

Comparison Between Actigraphy Records and Parental Reports of Child's Sleep

Given the impact of sleep in several domains of a child's development, the comparison between actigraphy and parental questionnaires is of great importance in preschool-aged children, an understudied group. While parental reports tend to overestimate sleep duration, actigraphy boosts the frequency of night-waking's. Our primary goal was to compare actigraphy data and parental reports (Children's Sleep Habits Questionnaire, CSHQ), regarding bedtime, wake-up time, sleep duration, and wake after sleep onset (WASO), using the Bland-Altman technique. Forty-six children, age 3-6 years, and their parents participated. Results suggest that, despite existing associations between sleep schedule variables measured by both methods (from r = 0.57 regarding bedtime at weekends to r = 0.86 regarding wake-up time during the week, ps), differences between them were significant and agreements were weak, with parents overestimating bedtimes and wake-up times in relation to actigraphy. Differences between actigraphy and CSHQ were ± 52 min for weekly bedtime, ± 38 min for weekly wake-up time, ±159 min for total sleep time, and ± 62 min for WASO, indicating unsatisfactory agreement between methods. Correlations between actigraphy data and CSHQ dimensions are also explored. Our study contributes to the knowledge of the characteristics of each instrument, along with their tendency to overestimate and underestimate certain sleep parameters. We conclude that a complementary use of both instruments would better inform clinical practice and research on a child's sleep.

“…We recommend future observational and interventional studies to incorporate other sleep measurements than sleep duration alone in their study design and to measure sleep at different ages (starting between age 1 or 6 months) with a combination of objective and subjective measures. 45,46,51 Objective measures are accelerometry or video recording 46 and subjective measures are 24-hour activity/sleep diaries and validated questionnaires, in which parents report sleep duration and regularity of bedtime as well as sleep quality, and sleep problems. 52 We assessed the methodological quality of each study with an adapted tool.…”

“…We recommend future researchers to qualify accelerometry in combination with parental report more accurate than parental report alone when nighttime or 24-hour sleep duration is measured after infant age of 6 months. 45 For the measurement of infant sleep problems, we recommend standardized questionnaires (e.a. Brief Infant Sleep Questionnaire).…”

“…They additionally conclude that parents report infant sleep more accurately by diary than by the Brief Infants Sleep Questionnaire. 45 Accelerometry can provide an objective estimate of movement, but does not detect the difference between sleep and wakefully lying still in small infants. It is considered a valid method to estimate sleep duration in older children, 46,47 but under the age of 2 years, it is so far only valid for nighttime sleep duration.…”

Sleep during Infancy and Associations with Childhood Body Composition: A Systematic Review and Narrative Synthesis

et al. 2020

View full text Add to dashboard Cite

Introduction: Prevention of childhood overweight should start as early as possible preferably in ''the first 1000 days of life.'' Sleep is one of the modifiable health behaviors during this age period, besides dietary intake and physical activity. The aim of this systematic review is to summarize the existing literature regarding the association between sleep during infancy (age £24 months) and body composition measures during childhood (age £12 years). Methods: We registered the protocol of this systematic review (PROSPERO registration no. CRD42018087088) and conducted the review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We searched for articles published until July 31, 2019 reporting on longitudinal associations with a minimal follow-up of 6 months. Methodological Quality was assessed and a narrative synthesis was performed. Results: We included 19 studies. Sleep was reported as sleep duration (n = 18) or sleep problems (n = 2). Sleep was assessed at least once before the age of 12 months in 14 out of the 19 studies. Methodological quality was rated as strong for five studies, moderate for five studies, and weak for nine studies. Conclusion: This narrative synthesis found inconsistent evidence that longer infant sleep duration during the first 2 years of life is associated with a healthier body composition during childhood.

Behavioral insomnia in infants and young children

In infants and young children, bedtime problems and night waking are common and the main presentations of insomnia. Poor sleep may critically impact the daytime functioning and mood of the child and their caregivers. A comprehensive sleep history, a sleep diary/log, and the BEARS sleep screen are useful for diagnosing sleep problems in young children. Behavioral therapies for this type of insomnia include extinction, bedtime fading with positive routines, and scheduled awakening. Previous studies of behavioral interventions for young children showed significant improvements in sleep-onset latency, night waking frequency, and night waking duration. Parent education about their child's sleep, bedtime routines, and sleep hygiene is essential for treatment.
